| Scheduled Release 8.2208.0 (aka 2022.08) 2022-08-?? | |
| - 2022-08-09: ksi bugfix: request cache size and send timeout issue fixed. | |
| Async service send timeout is not configurable and request cache size is too | |
| small to handle large amount of signing requests with small amount of permitted | |
| requests per aggregation round. For example user with max_requests = 4 results | |
| cache size 5 * max_requests or at least 256. When signing 300 log files cache | |
| will be too small resulting several unsigned blocks. When signing 200 log file | |
| cache will be adequate, but with rate of 4 signatures per second, it is only | |
| possible to sign 4 * 10 blocks before all requests that are not sent out will | |
| timeout. | |
| Fix for the issue is to make send timeout configurable and make the size of the | |
| cache depend on the value of send timeout. New configuration value | |
| sig.block.signtimeout="time, s" introduced that defines the time window wherein | |
| the block has to be signed. The size of the request cache is increased to | |
| 3 * max_requests * sign_timeout or at least 256. | |
| Thanks to Taavi Valjaots for the patch. | |
| - 2022-08-09: imjournal bugfix: segmentation fault in close journal | |
| Thanks to github user t-feng for the patch. | |
| - 2022-08-09: net subsystem: support sha256 for StreamDriverAuthMode="x509/fingerprint" | |
| Thanks to github user codemaker219 for the patch. | |
| - 2022-08-05: imfile bugfix: message loss/duplication when monitored file is rotated | |
| When a to-be-monitored file is being rotated, some messages may be lost or | |
| duplicated. In case of duplication, many file lines may be duplicated | |
| depending on actual timing. The whole bug was primarily timing depenedent | |
| in general. It most often was visible in practice when the monitored | |
| file was very frequently rotated (we had some report with every few | |
| seconds). | |
| Note that while we try hard to not lose any messages, input file | |
| rotation always has some loss potential. This is inevitable if | |
| the monitored file is being truncated. | |
| Also note that this bugfix affects imfile, only. It has nothing to do | |
| and no relation to rsyslog output files being rotated on HUP. | |

| - 2022-08-05: ksi bugfix: optimize processing of signer queue to fix delays. | |
| There is a worker queue where rsyslog KSI module collects events and signing | |
| requests. When queue is processed thread is periodically put to sleep. Previous | |
| implementation handles signature requests well but sleeps every time after | |
| handling new file open / close event. When several log files are opened or | |
| closed simultaneously process is significantly slowed down. Another issue is | |
| that thread always sleeps 1000ms that may be 2x longer than aggregation round. | |
| This slows down overall signing process. | |
| Fix for the issue is to simply not sleep after file open / close event if there | |
| are next items to be processed. To speed up the signing process, rsyslog uses | |
| KSI aggregator conf. to obtain the aggregation period that is used for the sleep | |
| time configuration. | |
| Thanks to Taavi Valjaots for the patch. | |
| - 2022-08-04: ksi bugfix: possible crash fixed when several log files are opened. | |
| KSI module in async mode used to request aggregator conf. every time a log | |
| file was opened. When several log files were opened simultaneously | |
| corresponding amount of pointless concurrent conf. requests were posted. | |
| Concurrent conf. requests lead to a bug in libksi, where internal count of | |
| pending requests was not decremented correctly causing system to crash. | |
| Fix for the issue is to optimize the frequency of conf. requests so that only | |
| one conf. requests is handled at once. Instead of checking conf. every time | |
| log file is opened, conf is requested periodically after conf timeout. This will | |
| affect both sync and async mode. | |
| New option for KSI module introduced - sig.confinterval="time, s". | |
| Thanks to Taavi Valjaots for the patch. | |
| - 2022-08-04: openssl: add support to split tls commands by semicolon | |

| - 2022-08-04: openssl subsystem bugfix: build issue on Solaris | |
| Needed header file was added. Platforms other than Solaris did not actually need it, | |
| so this bug was discovered late. | |
| Thanks to Jakub Kulík for the patch. | |
| Import <strings.h> when index() is used. | |
| - 2022-08-04: openssl: add more details to error messages | |
| - Avoid LogMsg outputs osslEndSess on successfull terminated | |
| connection. Only LogMsg if the connection was terminated | |
| unsuccessfully. | |
| - Handle SSL_ERROR_SYSCALL in both Send / osslRecordRecv, | |
| do not log as error if underlaying socket was terminated | |
| (ECONNRESET). Log as information instead. | |

| - 2022-08-04: mmanon bugfix: Simplified and fixed IPv4 digit detection. | |
| - Fixed an issue with numbers above int64 in syntax_ipv4. | |
| Numbers that were up to 256 above the max of an int64 | |
| could incorrectly be detected as valid ipv4 digit. | |
| - Simplified the IPv4 digit detection function and renamed | |
| to isPosByte. | |
| - added testcasse for malformed IPvc4 addresses | |

| - 2022-07-19: core bugfix: memory leak when free action worker data table | |
| During free action worker data table when action destruct, worker instance in worker | |
| data table were not null. It resulted in memory leak. | |
| Thanks to github user seuzw930 for the patch. | |
| - 2022-07-13: omfile: support for zstd compression | |
| The zstd library provides better and faster compression than zlib. | |
| This patch integrates zstd as a dynamically-loadable functionality. | |
| As such, no further dependencies need to be added to the rsyslog | |
| base package. | |
| Due to the increased performance, usage of zstd is highly recommended | |
| for high-volume use cases. | |
| This patch also refactor zlib compression in order to unify handling | |
| in both compression cases. | |
| - 2022-07-07: stream cleanup: move error message to debug log, only | |
| This error message is most probably rooted in a kernel problem. At | |
| least knowbody knows how it can happen. It's definitely not a | |
| rsyslog issue. We also can recover from it for a long time now | |
| so there is no reason to irritate users by emitteing this | |
| "error" message. | |
| - 2022-07-04: mmdblookup bugfix: Don't crash Rsyslog on mmdb file errors | |

| Scheduled Release 8.2206.0 (aka 2022.06) 2022-06-14 | |
| - 2022-05-25: omelastisearch: allow omitting _type field | |
| Allow omitting the _type field by setting it to an empty string. | |
| Setting this field has been deprecated since 6.0, and support will | |
| be removed in 8.0 | |
| Also add testbench test for empty searchType with ES 7.0 | |
| This checks for messages in the deprecation log and also provides | |
| avoids deprecation messages from usage of transport.tcp.port in the | |
| test configuration | |
| Thanks to Jarkko Oranen for the patch. | |
| - 2022-05-18: tcpsrv/imtcp: slight performance improvements | |
| This change slightly improves performance for tcpsrv-based servers. | |
| This affects imtcp and imgssapi as well as some helpers. | |
| No other functional change is included in this change. | |
| - 2022-05-12: imptcp bugfix: worker thread starvation on extreme traffic | |
| When connectes were totally busy, without any pause, the assigened worker | |
| did never terminate its reading loop. As such, it could not service any | |
| other conenctions. If this happened multiple time and to all configured | |
| workers, all other connections could not be processed at all. This extreme | |
| scenario is very unlikely, as the whole issue is relatively unlikely. | |
| In practice, the issue could lead to somewhat degraded performance and | |
| resolved itself after some time (in practice no connection is 100% busy | |
| for an extended period of time). | |
| Note that this patch sets a fixed limit of 16 iterations for very busy | |
| connections. This sounds like a good compromise between non-starvation | |
| and performance. The exact number may be made configurable if there | |
| is really need to. | |
| - 2022-05-11: omelasticsearch: several support option for ElasticSearch 8 | |
| - config params searchIndex and documentType can be empty | |
| - support for Data Stream API | |
| Thanks to github user EHerzog76 for these changes. | |
| - new config param esVersion.major | |
| - 2022-05-09: tcp receiver bugfix: delay/potential hang on some error conditions | |
| Error were not correctly handled in some cases for imtcp and imgssapi. This could | |
| lead to a temporary stall of some connections. For ultry-low traffic systems, this | |
| stall could stay for a long period of time. In most cases, it was resolved very quickly. | |
| Note that imptcp was not affected. | |
| Thanks to Iwan Timmer for the fix. | |
| - 2022-05-05: net bugfix: potential buffer overrun | |
| there is heap buffer overflow vulnerability in rsyslog tcp reception components. | |
| This can only happen in octet-counted mode, which is enabled by default. | |
| Affected components: imtcp, imptcp, imhttp, imgssapi, imdiag when octet-counted | |
| framing was enabled. | |
| If the receiver ports are exposed to the public Internet AND are used | |
| without authentication, this can lead to remote DoS and potentially to | |
| remote code execution. It is unclear if remote code execution is | |
| actually possible. If so, it needs a very sophisticated attack. | |
| When syslog best practices with proper firewalling and authentication | |
| is used, thean attack can only be carried out from within the Intranet | |
| and authorized systems. This limits the severity of the vulnerability | |
| considerably (it would obviously require an attacker already to be | |
| present inside the internal network). | |
| Credits to Peter Agten for initially reporting the issue and working | |
| with us on the resolution. | |
| fixes CVE-2022-24903 | |
| Advisory: | |
| https://github.com/rsyslog/rsyslog/security/advisories/GHSA-ggw7-xr6h-mmr8#advisory-comment-72243 | |
| - 2022-05-05: imptcp: set OS worker thread name | |
| We now set the worker thread names to "imptcp/<thrd nbr>" where | |
| <thrd nbr> is the numerical index (0, 1, ...) of the worker thread. | |
| This enables to distinguish individual worker threads in OS tools like | |
| htop. That is useful for performance testing and system monitoring. | |
| The choosen name format is consistant with other similar thread | |
| names inside rsyslog. For imptcp, worker threads were not yet | |
| given individual names. | |
| Note: "in:imptcp" is imptcp's "main" thread, which also is used | |
| as a worker in some scenarios. This name was not modified. | |
| - 2022-04-26: mmanon bugfix: shortened IPv6 form not always anonymized | |
| If the IPv6 is in non-recommended form followed by a 5 digit port number, it | |
| is not anonymized. | |
| A reproducer for this is: 1a00:c820:1180:c84c::ad3f:d991:ec2e:49255 | |

| failed to return specific field from data. | |

| - 2022-04-18: gnutls bugfix: possibility of infinite loop | |
| There was a rare possibility that the E_AGAIN/E_INTERRUPT handling | |
| could cause an infinite loop (100% CPU Usage), for example when a TLS | |
| handshake is interrupted at a certain stage. | |
| * After gnutls_record_recv is called, and E_AGAIN/E_INTERRUPT error | |
| occurs, we need to do additional read/write direction handling | |
| with gnutls_record_get_direction. | |
| * After the second call of gnutls_record_recv (Expand buffer) | |
| we needed to also check the eror codes for E_AGAIN/E_INTERRUPT | |
| to do propper errorhandling. | |
| * Add extra debug output based on ossl driver. | |
| * Potential fix for 100% CPU Loop Receiveloop after gtlsRecordRecv | |
| in doRetry call. | |

| - 2022-04-17: core/bugfix: errorfile could grow over max configures size | |
| When action.errorfile.maxsize configuration option is enabled and error file | |
| already has a certain size smaller than max size configured, it is increasing | |
| higher than configured max size as the error file is considered to be zero in code. | |
| This fix reads current error file size and limits the size to the maximum | |
| size configured. | |

| - 2022-04-17: omkafka bugfix: potential misadressing | |
| The `failedmsg_entry` expects a null-terminated string in `key`, but | |
| here we allocate with malloc and copy a string-with-length-n into only | |
| the first n bytes. If the final byte is null, this is by coincidence | |
| only. | |
| This was observed by means of seeing random binary data appended to | |
| keys submitted to kafka apparently at random. This could also result | |
| in more severe problems, inclusing a segfault. | |
| Thanks to David Buckley for the patch. | |
| - 2022-04-06: added new "FullJSONFmt" standard template (with addtl fields) | |
| This comes handy for a number of use cases, especially with ElasticSearch. | |
| Thanks to Art O Cathain for the patch. | |
| - 2022-04-04: imfile: potential processing delay | |
| This was mentioned by Mikko Kortelainen without exact details on what exactly | |
| this could cause in practice. But we were confident enough that it is worth | |
| merging (though it does not look like something that brought real problems in | |
| practice, as we do not know any related reports). | |
| see also: https://github.com/rsyslog/rsyslog/pull/4445 | |
| Thanks to Mikko Kortelainen for the patch. | |
| - 2022-04-04: bugfix: cosmetic data races | |
| there was a more or less cosmetic data race which could happen when children | |
| processes died in quick sequence. Even then, no real harm happened, as all | |
| children were reaped eventually. | |
| A similar data race exists for HUP processing. | |
| However, these races polluted TSAN test runs, and so we fixed them | |
| - 2022-04-01: add property options to support ISO week/year number | |
| Thanks to Mattia Barbon for the patch. | |
| - 2022-04-01: core bugfix: "action suspended" message was emitted even when turned off | |
| Most messages were diasabled, but there was one part of the code that ignored the | |
| user configuration. | |
| Thanks to Deyneko Aleksey for the patch. | |
| - 2022-03-31: testbench: add more tests for rscript comparison operations | |
| - 2022-03-31: core bugfix: make internal logs emitted during HUP procesing appear quicker | |
| After call doHUP(), probably there is a internal log in the list. However, it | |
| will not be wrote out immediately, because the mainloop will be blocked at | |
| pselect in wait_timeout() until a long timeout or next message occur. | |
| More deadly, the log may be lost if the deamon exits unexpectedly. | |
| We might as well put processImInternal() after doHUP(), so that the message | |
| will be flushed out immediately. | |
| Fixes: 723f6fdfa6(rsyslogd: Fix race between signals and main loop timeout) | |
| Thanks to Yun Zhou for the patch. | |
| - 2022-03-20: refactor: Move the parser directive to the main config | |
| Thanks to Attila Lakatos for the patch. | |
| - 2022-03-16: refactor: ake the main message queue part of the config | |
| The intent of this patch is to make the main message queue part of the main config. | |
| It will help us to proceed towards dynamic configuration reload. | |
| - regression bugfix: rsyslog may segfault during startup | |
| glblGetMaxLine() might be called even before the main configuration file exists | |
| resulting unexpected behavior, most probably segmentation fault. This is addressed | |
| by re-introducing the old default of 8KiB. The problem was introduced earlier in | |
| 2022. | |
| - regression fix: script string comparison did not work correctly | |
| In rscript, comparison operations on strings did not work correctly | |
| and returned false results. This is cause by a regression in commit | |
| 5cec5dd634e0. While it fixed number comparisons, it introduced new | |
| problems in string comparisons, which were not present before. Note | |
| that most items in rsyslog are strings, so this can actually cause | |
| some problems. | |

| Scheduled Release 8.2202.0 (aka 2022.02) 2022-02-15 | |
| - 2022-02-14: imfile bugfix: remove cause for "internal error message" (not causing harm) | |
| When any message is output into a renamed input file, rsyslogd output the following: | |
| message. | |
| imfile: internal error? inotify provided watch descriptor 7 which we could not find | |
| in our tables - ignored | |
| When rsyslogd detects the inode change, it deletes the entry from wdmap[]. But, | |
| the watch descriptor is not removed. Some application like sssd outputs some messages | |
| (like "HUP signal was received!!") after HUP signal is received and before switching | |
| into the new log file. And, the above messages can be output every log rotation. | |
| This situation is now resolved. | |
| Thanks to Masahiro Matsuya for the patch. | |
| - 2022-02-04: rscript bugfix: literal numbers were not compared correctly | |
| This problem occurred when numbers were used in rsyslog.conf in | |
| the set statement, e.g. | |
| set $nbr = 1234; | |
| In this case, during comparisons, the number was actually interpreted | |
| as a string with digits. Thus numerical comparisons lead to unexpected | |
| results. Even more so, as in other places of the code they were | |
| treated as native numbers. | |
| This is now fixed. We cannot outrule that this causes, in border cases, | |
| change of behavior to existing configs. But it is unlikely and the | |
| previous behaviour was a clear bug and very unintuitive. This in our | |
| opinion it is justified to risk a breaking change for an expected | |
| very minor subset of installations, if any such exists at all. | |

| Note that recovering is possible and was intended. | |
| Thanks to Kailash Sethuraman for the patch. | |
| - 2022-01-17: imtcp bugfix: worker threads were not properly terminated | |
| Graceful shutdown of Rsyslog could lead to segmentation faults when | |
| multiple imtcp inputs were being used. That is because the rest of the | |
| tcpsrv threads are left behind running, while their underlying objects | |
| are being disposed by the main thread as part of the module | |
| de-initialization. | |

| - 2021-11-18: mmanon: relax IPv6 detection - improve anonymization | |
| We so far tried to ensure a value is really an IPv6 address, in order | |
| to avoid to mangle with just similar-looking information elements. | |
| However, this lead to misdetection for unusual formats, e.g. when a | |
| port is appended to a numerical IPv6 adress given without braces []. | |
| This has been changed now. In a sense, we now prefer to err on the | |
| side of privacy. | |
| BEHAVIOR CHANGE: | |
| Previously, a suspect value was not anonymized, and thus some other | |
| elements (like some MAC addresses) preserved. Now the opposite is | |
| true, and we anonymize anything that looks close enough to be an | |
| IPv6 address. This improves anonymization. | |

| - 2021-11-10: ruleset bugfix: ruleset queue was incorrectly named | |

| - 2021-11-10: omsnmp: update module to current IP best practices | |
| The omsnmp module uses the inet_addr() function to convert the Internet host address | |
| from IPv4 numbers-and-dots notation into binary data in network byte order. If the input | |
| is invalid, INADDR_NONE (usually -1) is returned. Use of this function is problematic | |
| because -1 is a valid address (255.255.255.255). We should avoid its use in favor of | |
| inet_aton(), inet_pton(3), or getaddrinfo(3), which provide a cleaner way to indicate | |
| error return [1]. | |
| This is just a request to satisfy covscan, so no error is reported at all. | |
| Thanks to Attila Lakatos for the patch. | |
| - 2021-10-27: ommysql: fix threading bug | |
| When the MariaDB connection was (re)established, old or NULL handle | |
| could be used. This is fixed now. | |
| We need to synchronize access to the mysql handle, because multiple threads | |
| use it and we may need to (re)init it during processing. This could lead to | |
| races with potentially wrong addresses or NULL accesses. If this really | |
| matters mostly depends on the MariaDB/MySQL client library. It looks like | |
| they guard against fatal failuers. Anyhow, logging errors inside rsyslog | |
| could happen in any case. | |
| - 2021-10-25: testbench: false positive when impstats was not built | |
| Test omfwd_fast_imuxsock failed when impstats was not built. This | |
| has been corrected, test is now only executed when impstats is | |
| present. | |
| - 2021-10-25: imtcp: add support for permittedPeers setting at input() level | |
| The permittedPeers settig was actually forgotten during the refactoring | |
| of TLS input() level settings. This functionality is now added. | |

| Scheduled Release 8.2110.0 (aka 2021.10) 2021-10-19 | |
| - 2021-10-13: config bugfix: global(security.abortonidresolutionfail=) did not work | |
| when used with rscript based configuration, it was not checked. | |
| - 2021-10-13: config bugfix: global param $privDropToUser did not work correctly | |
| The parameter was not implemented for rscript based configuration and | |
| did not properly apply to legacy configuration. In essence, it almost always | |
| did not work as expected. | |

| - 2021-10-12: rscript bugfix: ruleset called async when ruleset had queue.type="direct" | |
| The call rscript statement is able to call a rule set either synchronously or | |
| asynchronously. We did this, because practice showed that both modes | |
| are needed. For various reasons we decided to make async | |
| calls if the ruleset has a queue assigned and sync if not. | |
| To know if a "queue is assigned" we just checked if queue parameters were | |
| given. It was overlookeded the case of someone explicitly specifying a | |
| "direct queue", aka "no queue". As such, queue="direct" triggered async | |
| calls. That in turn meant that when a write operation to a variable was | |
| made inside that rule set, other rulesets could or could not see the | |
| write. While if was often not seen, this was a data race where the | |
| change could also be seen by the outside. | |
| This is now fixed. No matter if queue.type="direct" is specified or | |
| left out, the call will always by synchronous. Any values written to | |
| variables will also be seen by the "outside world" in later processing | |
| stages. | |
| Note that this has some potential to BREAK EXISTING CONFIGURATIONS. | |
| We deem this acceptable because: | |
| 1. this was racy at all, so unexpected behaviour could alwas occur | |
| 2. it is actually unlikely that someone used the triggering conditions | |
| in practice. But we can not outrule this, especially when the | |
| configuration was auto-generated. | |
| Potential compatibility issues can be solved by defining a small | |
| array-memory queue on the ruleset in question instead of specifying | |
| direct type. | |
| Again, we expect that almost all users will never experience any | |
| problems. If you do, however, please let us know: we may add an | |
| option to re-enable the bug. | |

| tcpsrv.c:992:1: error: label at end of compound statement | |
| finalize_it: | |

| Quoting from pthread.h: | |
| pthread_cleanup_push and pthread_cleanup_pop are macros and must always | |
| be used in matching pairs at the same nesting level of braces. | |
| Amends commit bcdd220142ec9eb106550195ba331fd114adb0bd. | |
| Thanks to Orgad Shaneh for the patch. | |
| - 2021-10-11: mkubernetes bugfix: no connection retry to kubernetes APP | |
| When connection to the kubernates API was not possible, mmkubernetes | |
| did not retry. This does now happen via regular rsyslog retry | |
| mechanism. | |

| - 2021-10-11: openssl bugfix: Correct gnutlsPriorityString (custom ciphers) behaviour | |
| - Only apply default anon ciphers if gnutlsPriorityString is NULL and | |
| Authentication Mode is set to anon. Otherwise we do not set them | |
| as they overwrite custom Ciphers. | |
| - Added two tests for custom cipher configuration (anon/certvalid mode). | |
| - Add call for applyGnutlsPriorityString if gnutlsPriorityString changes. | |
| - Merged openssl init code from Connect into osslInitSession | |
| closes: https://github.com/rsyslog/rsyslog/issues/4686 | |
| - 2021-10-11: build issue: handle undefined MAXPATHLEN, PATH_MAX | |
| While we handled missing PATH_MAX, we did not handle missing MAXPATHLEN. | |
| This happens under GNU/Hurd, because there is no official limit. However, | |
| extremely long pathes are extremely uncommon, so we do not want to | |
| use slow dynamic alloc each time we need to build pathes. So we | |
| impose a limit of 4KiB, which should be fairly enough. Note that | |
| this obviously increases stack requirements in GNU/Hurd. | |
| As suggested by Michael Biebl, we have now implemented a generic | |
| approach to handle this via autoconf. | |
| - 2021-09-12: openssl: extended output information on connection failure | |
| Now includes the remote client/server IP address in the log output. | |
| - 2021-09-12: imhttp enhancements - query parameter ingestion & basic auth support | |
| - Basic Authentication support & tests | |
| * configured via imhttp option "basicAuthFile". This option should be configured | |
| to point to your htpasswd file generated via a standard htpasswd tool. | |
| tests: | |
| * imhttp-post-payload-basic-auth.sh | |
| * imhttp-post-payload-basic-auth-vg.sh | |
| - Query parameter ingestion capability & tests | |
| use t `addmetadata` option to inject query parameters into | |
| metadata for imhttp input. | |

| Thanks to Nelson Yen for the patch. | |
| - 2021-09-07: testbench bugfix: privdrop tests under root user did not work | |
| When running under root, the privdrop tests did not properly work. This | |
| patch fixes the issue and skips test where necessary. | |
| This also includes some modernization of the related tests. | |
| closes https://github.com/rsyslog/rsyslog/issues/4619 | |
| - 2021-09-07: core/ratelimiting: fix rate limiting for already parsed messages | |
| Rate limiting may not have worked if the considered message had already | |
| been parsed (not having NEEDS_PARSING in msgFlags). | |
| This affects also imuxsock in its default configuration | |
| (useSpecialParser="true" and ratelimit.severity="1") | |
| - 2021-09-07: core bugfix: use of property $wday terminates string | |
| When $wday is used inside a template, all template parts after it | |
| are ignored. For exmaple: | |
| template(name="json_filename" type="string" string="/var/log/%$wday%.log") | |
| would generate something like "/var/log/0" - the ".log" part would be | |
| missing. For the same reason, $wday can not reliably checked in script | |
| filters. | |
| Thanks to Alain Thivillon for reporting the bug and providing an | |
| excellent analysis, which essentiellay was exactly this fix here. | |
| closes https://github.com/rsyslog/rsyslog/issues/4670 | |
| - 2021-09-07: core/queue bugfix: potential misadressing when queue discarded messages | |
| When a discard mark was set, the queue was very busy and discarded messages, a | |
| NULL pointer access could happen. Depending on circumstances, several problems | |
| could occur, including a SEGFAULT. This is now fixed. | |
| closes: https://github.com/rsyslog/rsyslog/issues/4437 | |
| - 2021-09-07: imdiga bugfix: iOverallQueueSize calculation could be incorrect | |
| This issue only affects testbench and rsyslog development debugging. The active | |
| messages counter, used for synchronizing test steps, went wrong when the queue | |
| discarded messages on it's consumer thread. Now fixed. | |
| - 2021-09-06: gnutls driver: SAN priority did not work correctly on server side | |
| PrioritizeSAN was not propagated when accepting a new connection, this is now fixed. | |
| Thanks to Attila Lakatos for the patch. | |

| - 2021-08-16: openssl tls: Improved error message output on tls failures. | |
| closes: https://github.com/rsyslog/rsyslog/issues/4645 | |
| - 2021-08-16: impstats: add percentile metrics tracking functionality | |
| Brief overview: | |
| TO configure tracking percentile metrics in rainerscript: | |
| User would need to define: | |
| - which percentile to track, such as [p50, p99, etc.] | |
| - window size - note, this correlates directly with memory usage to | |
| track the percentiles. | |
| To track a value, user would call built-in function `percentile_observe()` in their configurations to | |
| record an integer value, and percentile metrics would be emitted every | |
| impstats interval. | |
| Thanks to Nelson Yen for the patch. | |
| - 2021-08-12: imfile: add parameter "ignoreolderthanoption" | |
| instructs imfile not to ingest a file that has not been modified in the | |
| specified number of seconds. | |
| Thanks to github user yanjunli76 for the patch (submitted from Nelson Yen) | |
| - 2021-08-10: imklog bugfix: invalid memory adressing, could cause abort | |
| This is a regeression from commit 94c4a87. It introduced a free() call | |
| using an object that was no longer valid (the main pointer to the | |
| to-be-freed object) was already freed at time of use. This could | |
| cause various issues, including a segfault. | |
| Note: this bug was triggerred only during late phase of rsyslog | |
| shutdown, so it did not affect regular operation. | |
| Special thanks to github user wxiaoguang for analyzing the issue | |
| and providing a draft fix proposal, on which this patch builds. | |
| see also https://github.com/rsyslog/rsyslog/pull/4629 | |
| closes https://github.com/rsyslog/rsyslog/issues/4625 | |
| - 2021-08-09: imfile bugfix: deleteStateOnFileDelete missed some state files | |
| When the log file is deleted, imfile would attempt to delete the statefile but it | |
| was missing the file_id part of the statefile name. This means the statefiles were | |
| only removed in the log file was less than 512 characters, because for very small | |
| files the file ID hash is not created. This lead to some state files not being | |
| deleted. | |
| Thanks to pearseimperva for the patch. | |
| - 2021-08-09: imfile bugfix: hash char invalidly added in readmode != 0 | |
| If imfile is ingesting log files with readMode set to 2 or 1, the resulting | |
| messages all have a '#' character at the end. This patch corrects the behaviour. | |
| Note: if some external script "supported" the bug of extra hash character at | |
| the end of line, it may be necessary to update them. | |
| closes https://github.com/rsyslog/rsyslog/issues/4491 | |
| - 2021-08-09: omelasticsearch bugfix: errorFile mutex was not consistently locked | |
| Lock the file during SIGHUPs to avoid issues with concurrent accesses by | |
| writeDataError(). | |
| Thanks to François Poirotte for the patch. | |
| - 2021-08-09: imudp: add socket type (IPv4 vs. 6) to input name | |
| Most importantly, the input name is used for stats counter names as | |
| well. Previously, the same name was used for IPv4 and IPv6, so we had | |
| two counters with an equal name. That left users puzzled. | |
| Unfortunately, this change can potentially require changes to existing | |
| analysis scripts, as the name is now slightly different. | |
| closes https://github.com/rsyslog/rsyslog/issues/4364 | |
| - 2021-08-06: omfwd: add capability for action-specific TLS certificate settings | |
| This permits to override the global definitions for TLS certificates | |
| at the action() level. | |
| - 2021-08-06: imfile bugfix: file handle leak if "freshStartTail" was turned on | |
| - 2021-08-05: imtcp: permit to use different certificate files per input/action | |
| This completes the ability to override global/default TLS settings at the imtcp | |
| input() level. Support for using multiple CAs/Certs per Connection is now provided. | |
| - 2021-08-04: imptcp bugfix: keep alive interval was incorrectly set | |
| The interval was accidentally set to keep alive interval. This has been | |
| corrected. | |
| closes https://github.com/rsyslog/rsyslog/issues/4609 | |
| - 2021-07-08: openssl network driver bugfix: small memory leak | |
| Fixes a static, non-growing memory leak which existed when parameter | |
| "GnutTLSPriorityString" was used. This was primarily a cosmetic issue, | |
| but caused some grief during development in regard to memory leak | |
| detectors. | |
| Note: yes, this is for openssl -- the parameter name is historical. | |
| - 2021-07-07: psrv bugfix: abort if no listener could be started | |
| Modules (like imtcp and imdiag) which use tcpsrv could abort or | |
| otherwise malfunction if no listener for a specific input could | |
| be started. | |
| Found during implementing a new feature, no report from practice. | |
| But could very well happen. | |
| - 2021-07-07: mmkubernetes bugfix: apiserver error handling | |
| - Added graceful handling of apiserver errors with unexpected responses, | |
| i.e., anything other than 200, 404, or 429. Idea is that apiserver | |
| transient error state will recover. We don't want mmkubernetes to miss | |
| metadata resolution for containers that don't have cached metadata. | |
| During these transient error states, mmkubernetes will provide basic | |
| container file path based resolution of namespace and pod metadata for | |
| new pods whose metadata is not yet cached. After this error state | |
| recovers, mmkubernetes is expected to resume its metadata resolution as | |
| expected. | |
| - Added a unit test case for apiserver return 500 with changes to mock server | |
| - Fixed existing unit test that was failing due to missing expected results file | |
| - Added mmkubernetes unit tests to testbench | |
| Thanks to Abdul Waheed for the patch (submitted from Nelson Yen). | |
| - 2021-07-07: ommongodb bugfixes | |
| - Fix Segmentation fault when server is down | |
| - Add server connexion check while resuming | |
| Thanks to Kevin Guillemot for the patch. | |
| - 2021-06-28: omkafka improvements | |
| - drain librdkafka queues and retry later during rsyslog restart or hup. This | |
| re-injects messages into rsyslog's native queues. | |
| - add statsname on per kafka instance for better visibility | |
| - omkafka - count errors related ssl as "errors_ssl" | |
| Thanks to Nelson Yen for the patch. | |
| - 2021-06-23: some CI/QA improvements, Travis-CI disabled | |
| For the time being, Travis CI is disabled because it was outdated and Travis also | |
| changed their system. We will re-evaluate if we re-enable it. Since quite a while | |
| the Travits tests were redundant with the rest of CI, so this does not reduce | |
| coverage. | |
| - 2021-06-23: omhttp bugfix: dynrestpath param in batch mode invalid | |
| When batchmode was used, the templates could not be used to | |
| expand dynrestpath. We are now storing the restpath param | |
| within the batch data if we are in batch mode. | |
| When we are in batch mode, and the restpath value changes, the | |
| batch is submitted and reinitialized | |
| closes: https://github.com/rsyslog/rsyslog/issues/4567 | |
| - 2021-06-17: add predefined template RSYSLOG_SyslogRFC5424Format | |
| This is essentially the same as RSYSLOG_SyslogProtocol23Format with | |
| a better name and a fix to remove the unnecessary LF at the end of | |
| the message. | |
| The different name also enables us to fix the LF issue without | |
| any concern about backwards compatibility. | |
| closes https://github.com/rsyslog/rsyslog/issues/4384 | |
| - 2021-06-17: impstats/bugfix: _sender_stats reports integer counter as string | |
| Note that this introduces a small backwards incompatibility: in previous output | |
| the field was of string type, now it is integer (as intended). We discussed this | |
| on the mailing list and the overwhelming thought was that this is not a problem | |
| because almost all analysis backends are able to cover that format change. This made | |
| the bugfix essentially costmetic. | |
| HOWEVER, if you still experience issues, please let us know. We can add an option | |
| to provide the previous format, and just spared to do so because there was no | |
| evidence it was needed. | |
| ---------------------------------------------------------------------------------------- | |
| Scheduled Release 8.2106.0 (aka 2021.06) 2021-06-15 | |
| NOTE: the prime new feature is support for TLS and non-TLS connections | |
| via imtcp in parallel. Furthermore, most TLS parameters can now be overriden | |
| at the input() level. The notable exceptions are certificate files, something | |
| that is due to be implemented as next step. | |
| - 2021-06-14: new global option "parser.supportCompressionExtension" | |
| This permits to turn off rsyslog's single-message compression extension | |
| when it interferes with non-syslog message processing (the parser | |
| subsystem expects syslog messages, not generic text) | |
| closes https://github.com/rsyslog/rsyslog/issues/4598 | |
| - 2021-05-12: imtcp: add more override config params to input() | |
| It is now possible to override all module parameters at the input() level. Module | |
| parameters serve as defaults. Existing configs need no modification. | |
| - 2021-05-06: imtcp: add stream driver parameter to input() configuration | |
| This permits to have different inputs use different stream drivers | |
| and stream driver parameters. | |
| closes https://github.com/rsyslog/rsyslog/issues/3727 | |
| - 2021-04-29: imtcp: permit to run multiple inputs in parallel | |
| Previously, a single server was used to run all imtcp inputs. This | |
| had a couple of drawsbacks. First and foremost, we could not use | |
| different stream drivers in the varios inputs. This patch now | |
| provides a baseline to do that, but does still not implement the | |
| capability (in this sense it is a staging patch). | |
| Secondly, we now ensure that each input has at least one exclusive | |
| thread for processing, untangling the performance of multiple | |
| inputs from each other. | |
| see also: https://github.com/rsyslog/rsyslog/issues/3727 | |
| - 2021-04-27: tcpsrv bugfix: potential sluggishnes and hang on shutdown | |
| tcpsrv is used by multiple other modules (imtcp, imdiag, imgssapi, and, | |
| in theory, also others - even ones we do not know about). However, the | |
| internal synchornization did not properly take multiple tcpsrv users | |
| in consideration. | |
| As such, a single user could hang under some circumstances. This was | |
| caused by improperly awaking all users from a pthread condition wait. | |
| That in turn could lead to some sluggish behaviour and, in rare cases, | |
| a hang at shutdown. | |
| Note: it was highly unlikely to experience real problems with the | |
| officially provided modules. | |
| - 2021-04-22: refactoring of syslog/tcp driver parameter passing | |
| This has now been generalized to a parameter block, which makes it much cleaner and | |
| also easier to add new parameters in the future. | |
| - 2021-04-22: config script: add re_match_i() and re_extract_i() functions | |
| This provides case-insensitive regex functionality. | |
| closes https://github.com/rsyslog/rsyslog/issues/4429 | |

| Scheduled Release 8.2104.0 (aka 2021.04) 2021-04-20 | |
| - 2021-04-19: new contributed module imhiredis | |
| Thanks to Théo Bertin (frikilax) for the patch. | |
| - 2021-04-19: new built-in function get_property() to access property vars | |
| Provides ability to evaluate a rsyslog variable using dynamically | |
| evaluated parameters. | |
| 1st param is the rsyslog param, 2nd param is a key, can be an array | |
| index or key string. | |
| Useful for accessing json sub-objects, where a key | |
| needs to be evaluated at runtime. Can be used to access arrays as well. | |
| Thanks to Nelson Yen for contributing this module. | |
| - 2021-04-19: mmdblookup: add support for mmdb DB reload on HUP | |
| Thanks to Théo Bertin (frikilax) for the patch. | |
| - 2021-04-19: script bugfix: empty array in foreach() improperly handled | |
| When running a foreach() loop inside a ruleset, if the json array/object iterated | |
| over is empty but valid, the foreach will make the message processing in the | |
| ruleset abort operation, no following operation (such as actions) will be | |
| executed after this. | |
| Thanks to Théo Bertin (frikilax) for the patch. | |
| - 2021-04-19: imjournal bugfixes (handle leak, empty file) | |
| Flush the FILE* buffer before rename & fsync in order | |
| to not end up syncing an empty file. | |
| Also, close WorkDir on fsync in order to prevent | |
| file descriptor leakage. | |
| Thanks to github user gerd-rausch for the fix. | |
| - 2021-04-06: new contributed function module fmunflatten | |
| This commit adds a new rainerscript function to unflatten keys in a JSON tree. It | |
| provides a way to expand dot separated fields. | |
| <result> = unflatten(<source-tree>, <key-separator-character>); | |
| It allows for instance to produce this: { "source": { "ip": "1.2.3.4", "port": 443 } } | |
| from this source data: { "source.ip": "1.2.3.4", "source.port": 443 } | |
| Thanks to Julien Thomas for the contribution. | |
| - 2021-02-22: test bugfix: some tests did not work with newer TLS library versions | |
| Newer versions provide TLS versions that cannot be disabled in older versions as they | |
| are unknown there. This is solved by setting restrictions in multiple steps. For | |
| older library versions, the final step will error out, but the other one be applied. | |
| This permits to achieve proper test results. | |

| Scheduled Release 8.2102.0 (aka 2021.02) 2021-02-16 | |
| - 2021-02-15: omfwd: add stats counter for sent bytes | |
| Thanks to John Chivian for suggesting this feature. | |
| - 2021-02-15: omfwd: add error reporting configuration option | |
| RSyslog on a plain TCP cannot guarantee the message delivery | |
| without using RELP protocol. Besides that the logs may be | |
| flooded with connection errors making the rest of messages | |
| difficult to find. To alleviate the problem (see issue 3910), | |
| this patch adds a configuration option that enables to reduce | |
| the number of network errors logged and reported. | |
| For example, if each 10th network error message should be logged, | |
| the rsyslog configuration has to be updated as follows. | |
| action(type="omfwd" Target="<IP_ADDR>" Port="<PORT>" Protocol="tcp" ConErrSkip="10") | |
| Thanks to Libor Bukata for the patch. | |
| - 2021-02-15: action stats counter bugfix: failure count was not properly incremented | |
| In some cases the counter was not incremented, most notably with transaction-enabled | |
| actions. | |
| Thanks to github user thinkst-marco for the patch. | |
| - 2021-02-15: action stats counter bugfix: resume count was not incremented | |
| And so it always stayed at zero. | |
| Thanks to github user thinkst-marco for the patch. | |
| - 2021-02-15: omfwd bugfix: segfault or error if port not given | |
| If omfwd is configured via RainerScript config format and the "port" | |
| parameter is not given, a segfault will most likely happen on | |
| connection establishment for TCP connections. For UDP, this is | |
| usually not the case. | |
| Alternatively, in any case, errors may happen. | |
| Note that the segfault will usually happen right on restart so this | |
| was easy to detect. | |
| We did not receive reports from practice. Instead, we found the bug | |
| while conducting other work. | |
| - 2021-01-29: lookup table bugfix: data race on lookup table reload | |
| A data race could happen when a lookup table was reloaded. We found | |
| this while moving to newer version of TSAN, but have no matching | |
| report from practice. However, there is a potential for this to cause | |
| a segfault under "bad circumstances". | |
| - 2021-01-18: testbench modernization | |
| Bump dependency versions, use newer distro versions for some tests. | |
| Make kafka distcheck separate to help diagnose flaky kafka tests. | |
| - 2021-01-16: testbench: fix invalid sequence of kafka tests runs | |
| kafka tests can not run well in parallel (mostly due to ressource | |
| constraints on CI machines). Accidentally, this was not enforced for | |
| one of the tests. That could lead to random failures and false positives. | |
| - 2021-01-14: testbench: fix kafkacat issues | |
| The kafkacat tool has an upper limit of how many messages it can send | |
| at once. Going over that limit causes messages loss. The exact limit | |
| seems to depend on the environment. This causes testbench false positives. | |
| This commit fixes two related issues: | |
| - errors during kafkacat run were not detected - this has been added | |
| - we now have a "max messages at once" setting, after which kafkacat | |
| is restarted for the next batch of messages. It currently is set | |
| to 25,000 msgs per incarnation. All tests loop now to send the | |
| required number of messages. This has been fixed at the testbench | |
| framework level, so no need to adjust individual tests. | |
| - 2021-01-14: testbench: fix year-dependendt clickhouse test | |
| A test had the year value hardcoded and as such failed whenever the | |
| year changed. This patch corrects that. | |

| error messages emited in rsyslog status. This was not the case. That in turn could | |

| If the tls handshake does not immediatelly finish, gnutls_handShake is called in | |
| doRetry handler again. However the error handling was not | |
| complete in the doRetry handler. A failed gnutls_handShake call | |

| There is a missing call to json_object_put(json) if the call to | |

| Performing a condition (eg: check for an empty string) on a subtree key that do not | |
| exists (depth > 1 from the root container), creates an empty "parent" object. | |
| Depending on your context, you may end up with (kind of...) annoying garbage when | |

| - 2020-09-28: gnutls subsysem bugfix: potential hang on session closure | |
| Some TLS servers don't reply to graceful shutdown requests "for | |
| optimization". This results in rsyslog's omfwd+gtls client to wait | |
| forever for a reply of the TLS server which never comes, due to shutting | |
| down the connection with gnutls_bye(GNUTLS_SHUT_RDWR). | |
| On systemd systems, commands such as "systemctl restart rsyslog" just | |
| hang for 1m30 and rsyslogd gets killed upon timeout by systemd. | |
| This is fixed by replacing the call to gnutls_bye(GNUTLS_SHUT_RDWR) by calls to | |
| gnutls_bye(GNUTLS_SHUT_WR) which is sufficient and doesn't wait for a | |
| server reply. | |
| As an example, Kiwi Syslog server is known to cause this issue. | |
| Thanks to Renaud Métrich for the patch. | |
| - 2020-09-23: core/network bugfix: obey net.enableDNS=off when querying local hostname | |

| non -1 while the buffer has not yet properly set up. | |

| - 2020-08-26: cosmetic: fix dummy module name in debug output | |
| When we have optional components (like imjournal) a dummy module | |
| is used. It's sole purpose is to emit "this module is not available". | |
| During init, the module emitted an invalid module name into the debug | |
| log. This has now been replaced by the generic term "dummy". | |
| Note: it is highly unlikely that someone will ever see that message | |
| at all, as it is unlikely for the dummy modules to be build. | |

| - 2020-08-26: config bugfix: intended warning emitted as error | |
| When there are actions configured after a STOP, a warning should be | |
| emitted. In fact, an error message is generated. This prevents the | |
| construct, which may have some legit uses in exotic settings. It | |
| may also break older configs, but as the message is an error | |
| for so long now, this should be no longer of concern. | |

| The issue happens when more than one server is defined on the | |
| action. On that condition a health check is made through | |
| checkConn() before sending the POST. The replyLen should be | |
| set back to 0 after the health check, otherwise the response | |

| - 2020-08-14: omfile: do no longer limit dynafile cache size in legacy format | |
| When using obsolete legacy config format, omfile had a hard limit of | |
| 1,000 dynafile cache entries. This does not play well with very | |
| large installation. This limit is now removed and converted into | |
| a warning if cache size > 25,000 is specified. | |

| - 2020-08-13: imudp: fix very small, static memory leak | |
| When ruleset support was used, the ruleset name was not freed upon rsyslog | |

| - 2020-04-29: omudpspoof bugfix: issues with oversized messages | |
| First issue was an incorrect packet length in UDP Header. It has to be the FULL UDP Packet | |
| regardless of the MTU Setting. As a result regardless of IP fragmentation, the MTU setting | |
| also limited the siizmax size of the UDP message. | |
| The second issue was incorrect calculation of the UDP Checksum with libnet if | |
| IP fragmentation was used (Based on MTU Setting). As a result, the network packets were | |
| dropped by the tcp stack before they even could reach there target. The workarround for this | |
| problem is, that we set the UDP Checksum to 0x0000 which allows skipping of the checksum | |
| test. Fixing the problem by calculating the correct UDP Checksum would require some | |
| code changes in the libnet. | |
| Also fixed the omudpspoof bigmsg test and increased the testing size to 16KB. | |
| - 2020-04-29: omprog: fix assert failed on HUP with output flag | |
| If the 'output' setting of omprog was used and rsyslog received a HUP | |
| signal just after starting (and before the omprog action received the | |
| first log to process), an internal assertion could fail, causing | |
| rsyslog to terminate. The failure message was "rsyslogd: omprog.c:660: | |
| closeOutputFile: Assertion `pCtx->bIsRunning' failed." | |
| The failure could also occur if rsyslog received a HUP signal during | |
| the shutdown sequence. | |
| This bug was introduced in v8.2004 by PR https://github.com/rsyslog/rsyslog/pull/4255 | |
| Although a test already existed that checked the interaction of HUPs | |
| with the 'output' setting, it didn't always fail in this particular case | |
| due to timing conditions. The test has been improved to cover this case | |
| more reliably. | |

| - 2020-04-28: omprog: fix bad fd errors in daemon mode | |
| When omprog was used with the 'forceSingleInstance=on' option, and/or | |
| the 'output' setting, "bad file descriptor" errors occurred, which | |
| prevented the external program to be executed and/or the program output | |
| to be correctly captured. The bug could also manifest as "resource | |
| temporarily unavailable" errors, or other errors related to the use of | |
| invalid/reassigned file descriptors. These errors only happened when | |
| rsyslog ran in daemon mode (i.e. they didn't happen if rsyslogd was | |
| run with the '-n' option). | |
| The cause of the bug was that omprog opened the pipe fds needed by | |
| these flags during the configuration load phase (in the 'newActInst' | |
| module entrypoint). This is a bad place since the fork of the daemon | |
| occurs after this phase, and all fds are closed when the daemon process | |
| is started (see 'initAll' in rsyslogd.c), hence invalidating the | |
| previously opened fds. | |
| To correct this, the single child process and the output capture thread | |
| are now started later, when the first log message is received by the | |
| first worker thread. (Note: the 'activateCnf' module entrypoint, despite | |
| being invoked after the fork, cannot be used for this purpose, since it | |
| is invoked per module, not per action instance.) | |
| Currently no automated test exists for this use case since the testbench | |
| always runs rsyslog in non-daemon mode. | |

| - 2020-02-24: core: add global parameter "security.abortOnIDResolutionFail" | |
| This parameter controls whether or not rsyslog aborts when a name ID | |
| lookup fails (for user and group names). This is necessary as a security | |
| measure, as otherwise the wrong permissions can be assigned or privileges | |
| are not dropped. | |
| CHANGE OF BEHAVIOR | |
| The default for this parameter is "on". In previous versions, the default | |
| was "off" (by virtue of this parameter not existing). As such, existing | |
| configurations may now error out. | |
| We have decided to accept this change of behavior because of the potential | |
| security implications. | |

| This was supported since always inside GnuTLS driver, but was missing for openssl one. | |
| - 2020-02-24: core bugfix: too early parsing of incoming messages | |
| In theory, rsyslog should call parsers on the queue worker threads whenever | |
| possible. This enables the parsers to be executed in parallel. There are | |
| some cases where parsers needs to be called earlier, namely when parsed | |
| data is needed for rate-limiting. | |
| The logic to do this previously did not work correctly and was fixed six | |
| years ago (!) by b51dd22. Unfortunately, b51dd22 was overly agressive: | |
| it actually makes the early parser call now mandatory, effectively moving | |
| parsing to the input side where there is no to little concurrency. | |
| We still do not need to call the parser when all messages, regardless of | |
| severity, need to be rate-limited. This is the default and very frequent | |
| case. This patch introduces support for this and as such makes parsers | |
| able to run in parallel in the frequent case again. | |

| - 2020-02-09: imfile bugfix: timeout did not work on very busy system | |
| The timeout feature was soley based on timeouts of the poll() | |
| system call. On a very busy system, this would probably happen | |
| very seldomly. Moreover, the timeout could occur later than | |
| expected on any system with high load. | |
| The issue was not reported from practice but discovered during | |
| CI system improvements. | |
| - 2020-01-30: build system: change --enable-imfile-tests default to "yes" | |

| Since the upgrade of the package libmaxminddb on FreeBSD (1.3.2_2 -> 1.4.2), | |
| the module mmdblookup returns the first entry of the mmdb database even if the entry | |
| is not found. After some debug, I found the solution in the official maxminddb | |
| repository : to check if the entry is in database, we must check the found_entry | |
| attribute, otherwise the function MMDB_get_entry_data_list will return the first | |
| entry of the database if the entry is not found in it. | |
| Thanks to Kevin Guillemot for the patch. | |
| - 2020-01-23: oversize message log bugfix: do not close fd -1 | |
| The oversize message log fd is always closed on HUP, even if it never | |
| was opened (and thus has -1 value). This patch corrects the issue. | |
| The bug had no know-bad effect in practice other than getting an | |
| (ignored) error status from close(). However, it introduced warnings | |
| in test runs (e.g. when running under valgrind). | |
| - 2020-01-22: imfile bugfix: saving of old file_id for statefiles | |

| - 2020-01-22: imfile bugfix: misadressing and potential segfault | |

| could lead to segfaults or other hard to find problems. | |
| The issue was detected by our upgraded CI system. We did not receive | |
| any problem reports in practice. Nevertheless, the problem is real and | |
| people should update affected versions to patched ones. | |
| The bug was present in scheduled stable release 8.1911.0 and 8.2001.0. | |

| The problem occurred with commit 3d9b8df in December 2018 and went into | |

| until a year later. This commit re-enables the previous default ("off"), which is | |
| also the only sensible default from a security PoV. Unfortunately, new 2019 | |
| deployments may begin to see connection rejection when usin expired certs. As | |
| expired certs should not be used, this hopefully will not cause problems in | |
| practice. | |

| - 2019-12-27: core bugfix: reopen /dev/urandom file descriptor after fork on Linux | |
| This patch updates prepareBackground() in tools/rsyslogd.c to reopen any file | |
| descriptors used for random number generation in the child process. This fixes | |
| an issue on Linux systems where the file descriptor obtained for /dev/urandom | |
| by seedRandomNumber() in runtime/srutils.c was left closed after the fork. This | |
| could be observed in procfs, where /proc/fd/ would show no open descriptors to | |
| /dev/urandom in the forked process. /dev/urandom is reopened as the child may be | |
| be operating in a jail, and so should not continue to use file descriptors from | |
| outside the jail (i.e. inherited from the parent process). | |
| I found that this issue led to rsyslog intermittently hanging during seedIV() | |
| in runtime/libgcry.c. After the fork, the closed file descriptor number tended | |
| to get re-assigned. randomNumber() would then read from an incorrect (although | |
| still valid) file descriptor, and could block (depending on the state of that | |
| file descriptor). This gave rise to the intermittent hang that I observed. | |

| Loki is a new message indexer and querier from Grafana Labs. See | |
| https://github.com/grafana/loki for details on Loki. | |
| This change provides the initial message structure to send bulk message | |
| payloads to the Loki Rest endpoint. omhttp, received a new bulk message | |
| format called lokirest. Additionally, the plugin relies on the user to | |
| provide the correct "stream" read message format. | |
| A loki template must be json compatible and include a "stream" key of | |
| key value tags, and a values key of an array of 2 element arrays, where | |
| each 2 element array is the unix epoch in nanoseconds followed by an | |
| unstructured message. | |
| An example: | |
| template(name="array_loki" type="string" string="{\"stream\":{\"host\":\"%HOSTNAME%\",\"facility\":\"%syslogfacility-text%\",\"priority\":\"%syslogpriority-text%\",\"syslogtag\":\"%syslogtag%\"},\"values\": [[ \"%timegenerated:::date-unixtimestamp%000000000\", \"%msg%\" ]]}") | |

| - 2019-11-22: omprog: detect violation of interface protocol | |
| The spec for the omprog interaction with the program it calls specifies | |
| that the program receives one message via one line. In other words: | |
| it must be a string terminated by LF. | |
| However, omprog does currently rely on a proper template to fulfill this | |
| requirement, If the template does not provide for the LF, it is never | |
| written. For the called program, this looks like it does not receive any | |
| input at all. Even if it finally reads data (e.g. due to full buffer), | |
| it will not properly be able to discern the messages. | |
| This handling is improved with this commit. | |
| We cannot just check the template, because at the end of the template | |
| may by a non-constant value. As such, we do not know at config load | |
| time if there is this problem or not. | |
| So the correct approach is to, during runtime, check if each message | |
| is properly terminated. For those that are not: | |
| * we append a LF, because anything else makes matters worse | |
| * log a warning message, at least for a sample of the messages | |
| The warning is useful in the (expected most often) case that the template | |
| is simply missing the LF. While appending works, it slows down processing. | |
| As such the user should be given a chance to correct the config bug. | |
| To avoid clutter, the warning is emitted at most once every 30 seconds. | |
| This value is hardcoded as we do not envision a need to adjust it. Usually | |
| users should quickly fix the template. | |

| loss of journal data. | |
| This commit adjust it to 100ms, which should still be fully sufficient | |
| to prevent the journal from "hammering" the CPU. | |
| It may be worth considering to make this setting configurable - but | |
| let's first see if there is real demand to actually do that. | |

| - 2019-11-19: mmutf8fix: enhance handling of incorrect UTF-8 sequences | |
| 1. Invalid utf8 detection didn't handle 3 and 4-byte overlong encodings (2 | |
| byte overlong encodings were handled explicitly by rejection E0 and E1 | |
| start bytes). Unified checks for overlong encodings. | |
| 2. Surrogates U+D800..U+DFFF are not valid codepoints (Unicode Standard, D92) | |
| 3. Replacement of characters in invalid 3 or 4-bytes encodings was too | |
| eager. It must not replace bytes which are valid UTF-8 sequences. For | |
| example, in [0xE0 0xC2 0xA7] sequence the 0xC2 is invalid as a continuation | |
| byte, but it starts a valid UTF8 symbol [0xC2 0xA7]. That is, with current | |
| code processing the sequence will result in "???" but the correct result is "?§" | |
| (provided that the replacement character is "?"). | |

| Scheduled Release 8.1911.0 (aka 2019.11) 2019-11-12 | |
| - 2019-11-12: core queue: add config param "queue.takeFlowCtlFromMsg" | |
| This is a fine-tuning option which permits to control whether or not | |
| rsyslog shall alays take the flow control setting from the message. If | |
| so, non-primary queues may also block when reaching high water mark. | |
| This permits to add some synchronous processing to rsyslog core engine. | |
| However, it is dangerous, as improper use may make the core engine | |
| stall. As such, enabling this option requires very careful planning | |
| of the rsyslog configuration and deep understanding of the consequences. | |
| Note that the option is applied to individual queues, so a configuration | |
| with a large number of queues can (and must if use) be fine-tuned to | |
| the exact use case. | |
| The rsyslog team strongly recommends to let the option turned off, | |
| which is the default setting. | |
| see also https://github.com/rsyslog/rsyslog/issues/3941 | |
| - 2019-11-12: imrelp: add new config parameter "flowcontrol" | |
| This permits to fine-tune the flowControl parameter. Possible values are | |
| "no", "light", and "full". With light being the default and previously | |
| only value. | |
| Changing the flow control setting may be useful for some rare applications, | |
| but be sure to know exactly what you are doing when changing this setting. | |
| Most importantly, whole rsyslog may block and become unresponsive if you | |
| change flowcontrol to "full". While this may be a desired effect when | |
| intentionally trying to make it most unlikely that rsyslog needs to | |
| lose/discard messages, usually this is not what you want. | |

| removed that debug info as it is no longer vital. | |
| Note: this could only happen during debug runs. Production mode was | |
| not affected. As such, this fix is only relevant to developers. | |
| However, it caused some confusion in the following issue tracker. | |

| When data is read from the journal using sd_journal_get_data it may be | |
| truncated to a certain threshold (64K by default). | |
| If the rsyslog MaxMessageSize is larger than the threshold, there is a | |
| chance rsyslog will receive incomplete messages from the journal. | |
| Empirically, this appears to happen reliably when XZ compression is | |
| used by journald. Systems where journald uses LZ4 compression do not | |
| appear to suffer this issue reliably--if at all. | |
| This change sets the threshold to the MaxMessageSize when the | |
| journal is opened. | |
| Thanks to Robert Winslow Dalpe for the patch. | |

| - 2019-10-30: mmdblookup bugfix: missing space in city name | |
| This fixes the issue that spaces in city names are dropped. However, the | |
| fix is more or less a work-around. As it turns out, the libmaxminddb API | |
| is not correctly used. In the somewhat longer term, we should fix this. | |

| - 2019-10-30: core/queue: provide ability to run diskqueue on multiple threads | |
| Up until this release, disk queues could only use a single thread, | |
| what limited their performance with outputs like ElasticSearch. | |
| Now disk queues can utilize multiple threads just like any other | |
| queue type. Most importantly, the disk queue part of a DA queue | |
| now inherits the max number of threads from its memory queue | |
| counterpart. | |
| NOTE: the new multi-threaded DA disk queue is actually a change of | |
| behavior. We have not guarded it by a new config switch as we | |
| assume the new behavior is most often exactly within user | |
| expectations. In any case, we cannot see any harm from running | |
| the disk queue on multiple threads. | |

| - 2019-10-25: omfile bugfix: file handle leak | |
| The stream class does not close re-opened file descriptors. | |
| This lead to leaking file handles and ultimately to the inability | |
| to open any files/sockets/etc as rsyslog ran out of handles. | |
| The bug was depending on timing. This involved different OS | |
| thread scheduler timing as well as workload. The bug was more | |
| common under the following conditions: | |
| - async writing of files | |
| - dynafiles | |
| - not committing file data at end of transaction | |
| However it could be triggered under other conditions as well. | |
| The refactoring done in 8.1908 increased the likelihood of | |
| experiencing this bug. But it was not a real regression, the new | |
| code was valid, but changed the timing so that the race was more | |
| likely. | |
| Thanks to Michael Biebl for reporting this bug and helping to | |
| analyze it. | |

| - 2019-10-16: core queue bugfix: propagate batch size to DA queue | |
| This was a long-standing bug where the DA queue always had a fixed small batch | |
| size because the setting was not propagated from the memory queue. This also | |
| removes a needless and counter-productive "debug aid" which seemed to be in | |
| the code for quite some while. It did not cause harm because of the batch | |
| size issue. | |
| - 2019-10-16: testbench: fix unreliable gzipwrite test | |
| The test was timing-sensitive as we did not properly check all data | |
| was output to the output file - we just relied on sleep periods. | |
| This has been changed. Also, we made some changes to the testing | |
| framework to fully support sequence checking of multiple ZIP files. | |
| - 2019-10-16: core queue bugfix: handle multi-queue-file delete correctly | |
| Rsyslog may leave some dangling disk queue files under the following | |
| conditions: | |
| - batch sizes and/or messages are large | |
| - queue files are comparatively small | |
| - a batch spans more than two queue files (from n to n+m with m>1) | |
| In this case, queue files n+1 to (n+m-1) are not deleted. This can | |
| lead to problems when the queue is re-opened again. In extreme cases | |
| this can also lead to stalled processing when the max disk space is | |
| used up by such left-over queue files. | |
| Using defaults this scenario is very unlikely, but it can happen, | |
| especially when large messages are being processed. | |
| - 2019-10-16: imjournal: fix regression from yesterday's patch | |
| commit 78976a9bc059 introduced a regression that caused writing | |
| the journal state file to fail. This happens when the state file | |
| is given as relative file name and the working directory is also | |
| a relative path. This situation is very uncommon. So most deployments | |
| will never experience it. We discovered the issue during CI runs | |
| where the trigger condition is given. Note that it also takes | |
| multiple times of loading the journal to actually see the bug. | |
| see also https://github.com/rsyslog/rsyslog/pull/3878 | |
| - 2019-10-15: imjournal plugin code restructuring, added remote option | |
| Decomposed ReadJournal() a bit, also now coupling journald | |
| variables in one struct, added few warning messages and debug | |
| prints to help with bug hunts in future, also got rid of two | |
| needless journald calls. WorkAroundJournalBug now deprecated. | |
| Added option to pull journald records from outside local machine. | |
| Thanks to Jiri Vymazal for the patch. | |
| - 2019-10-11: core bugfix: potential abort on very long action name | |
| The action name is stored in modified form for the debug header and | |
| some messages. If it is extremely long, a buffer can be overrun, | |
| resulting in misaddressing and potential segfault for rsyslog. This | |
| can also happen if the action is NOT named, but a custom path to | |
| the output module is given and that path is very long. This triggers | |
| the same issue because by default the module load path is included | |
| in the action name. | |
| This patch corrects the problem and truncates overly long names | |
| when being used for name generation. | |
| The problem was detected during testbench work. We did never receive | |
| a bug report from practice. | |

| - 2019-10-01: core bugfix: incorrect error message on duplicate module load | |
| A Null-pointer was passed to printf instead of the module name. | |
| On some platforms this may lead to a segfault. On most platforms | |
| printf check's for NULL pointers and uses the string "(null)" | |
| instead. In any case, the module name is missing from the error message. | |
| - 2019-10-01: imczmq nitfix: potential NULL ptr in printf on out-of-memory condition | |
| very unlikely to happen but if it does without any real issue on most platforms. | |
| - 2019-10-01: work around some compiler warning messages induced by pthreads API | |
| - 2019-10-01: core ratelimiting: more verbose message when rate-limiting happens | |
| When messages are rate-limited, the error message now also contains the | |
| rate limiter setting. This enables the user to more quickly understand what | |
| the problem is (especially if default values apply). | |
| Thanks to Jiri Vymazal for the patch. | |
| - 2019-10-01: openssl TLS driver: do not emit unnecessary error message | |
| On older openssl versions, an API was missing to set user-defined parameters. If we | |
| had such an older version, rsyslog emitted an error message even if the user did | |
| not configure such parameters. This has been corrected, so that a message is only | |
| emitted if there really is a problem. Based on user feedback the severity has also | |
| been downgraded to "warning". | |

| rsyslog fails to cross build from source, because it uses mysql_config | |
| and mysql_config is unfixably broken for cross compilation. It would be | |
| better to use pkg-config. The attached patch makes rsyslog try | |
| pkg-config first and fall back to mysql_config. | |

| - 2019-08-20: core/tcpsrv: potential race on startup/shutdown | |
| if the tcpsrv component is started and quickly terminated, it may hang | |
| for a short period of time. Also a very small amount of memory is leaked | |
| immediately before shutdown. While this leak is irrelevant in practice | |
| (the OS clean up the process anyways), it leads to CI failures. The hang, | |
| however, can lead to longer than expected shutdown times for rsyslog. | |
| The problem can be experienced via imtcp, imgssapi and imdiag (users | |
| of affected core component). | |

| - 2019-08-19: testbench: harden some tests against very slow CI machines | |
| - 2019-08-16: testbench: make most tests use a port file and assign listen port 0 | |

| - 2019-08-16: core/action: guard action.externalstate.file content against whitespace | |
| remove trailing whitespace before checking the status string. This is | |
| most important as a line usually ends with \n, which is considered | |
| trailing whitespace. Accepting this increases usability. | |
| - 2019-08-16: imtcp bugfix: multiple listenerPortFile parameter did not work | |

| - 2019-08-16: testbench: improve testbench plumbing for gzip and fail cases | |
| We have added new capabilities to the testbench plumbing to automatically | |
| deal with gzip-compressed files. This also permits to use the wait_seq_check | |
| function to work for gzip tests as well. The known-timing-sensitive | |
| gzipwr_large test now makes use of the new capabilities. This enables us | |
| to more reliably detect when we can savely shutdown the tested instance. | |
| This commit also adds an ability to "abort" the full testbench run on | |
| first test failure. This is especially useful during CI. | |
| - 2019-08-13: testbench: add test for imuxsock legacy format | |
| This was never tested. Ensures we don't accidentally break existing | |
| configurations. | |
| - 2019-08-13: omelasticsearch bugfix: segfault on unknown retryRuleset | |
| omelasticsearch does some "interesting tricks" for an output module. | |
| This causes a segfault if the retryRuleset is now known. | |
| The action module interface currently expects that all config errors | |
| be detected during instance creation. Instead omelasticsearch defers | |
| the retry ruleset check to a later state. The reason is that it wants | |
| to support the use the same rulesetname it is defined in - and this | |
| is not yet available at action parsing. | |
| We fix this by ensuring that any deleted instance is properly unlinked | |
| from the instance list. One may argue the module interface should get | |
| upgrade for such cases, but this is a longer-term approach. | |

| - 2019-08-12: imptcp bugfix: port="0" parameter did not work as expected | |
| when multiple interfaces and/or protocols could be bound, each of | |
| them used a different listener ports were assigned. While this is | |
| basically correct, it makes things unusable, especially as | |
| listenPortFileName will only contain the port number used for | |
| the latest listener. | |
| This patch now follows the model of nsd_ptcp.c to assign only | |
| the first port randomly and then use that port consistently. | |
| - 2019-08-10: omelasticsearch bugfix: potential resource leak with "rebindinterval" | |
| If the "rebindInterval" parameter was used connections could be linked. This | |
| was especially the case with small intervals (such as "2"). This is fixed by | |
| forcing libcurl to close the connection on rebind. | |
| Thanks to Noriko Hosoi for providing the patch. | |
| - 2019-08-10: imjournal bugfix: state file close with fsync() was incorrect | |
| This lead to fsync() now always applied where expected. | |
| Thanks to Jiri Vymazal for the patch. | |
| - 2019-08-10: testbench: add addtl test for multithreading and HUP | |
| - 2019-08-10: imptcp bugfix: received bytes counter improperly maintained | |
| imptcp counts the number of bytes received. However, receives | |
| happen on different worker thread. The access to the counter | |
| was not synchronized, which can cause loss of updates. Also, | |
| thread debuggers validly flag this as an error, which creates | |
| problems under CI. | |
| This commit fixes the situation via atomic operations and | |
| falls back to mutex calls if they are not available. | |

| utilize LLVM TSAN in CI. | |
| - 2019-08-02: testbench: new test for omfile outchannel functionality | |

| memory corruption or segfault. | |

| - 2019-08-01: omfile bugfix: race file when async writing is enabled | |
| This seems to be a long-standing bug, introduced around 7 years ago. | |
| It became more visible by properly closing files during HUP, which | |
| was done in 8.1905.0 (and was another bugfix). Note that due to this | |
| race a memory corruption can occur under bad circumstances. As such, | |
| this may have also caused segfaults or system hangs (mutexes could | |
| have been affected). | |

| - 2019-07-23 iminternal bugfix: suppress mutex double-unlock | |
| If there is a burst of log messages during a time when rsyslog is unable | |
| to output (either during log rotation, an out-of-space condition, or | |
| some other similar condition), rsyslog can SEGFAULT due to a mutex | |
| double-unlock. | |
| - 2019-07-23 imtcp: enable listenPortFileName parameter | |
| this parameter was added, but it had no effect as it was not | |
| passed down to the driver layer. This has been fixed. That also | |

| very useful for further testbench stabilization. Quite some | |
| false positives occurred because the pre-selected port was | |
| already in use again when rsyslog started. | |

| Version 8.1907.0 (aka 2019.07) 2019-07-09 | |
| NOTE TO MAINTAINERS: libee is not used by rsyslog for quite some while. | |
| However, we never included this info into the changelog. So if you still | |
| make rsyslog depend on libee (some do this), you should stop doing so now. | |
| Libee is dead and no longer been maintained nor hosted by us. Old versions | |
| can still be found at github for those in need. | |
| GENERAL NOTE: during 8.1907 scheduled release timeframe we changed the ChangeLog | |
| format to include the date a change went into master branch. This is to provide | |
| an easy way to identify which changes went into the respective daily stable. | |
| - 2019-07-05 imuxsock: support FreeBSD 12 out of the box | |
| FreeBSD 12 uses RFC5424 on the system log socket by default. This | |
| format is not supported by the special parser used in imuxsock. | |
| Thus for FreeBSD the default needs to be changed to use the | |
| regular parser chain by default. That is all this commit does. | |

| - omamqp1: port to latest api, add tests | |
| This brings omamqp1 up-to-date with the latest qpid-proton-c | |
| api version. This also adds a test for the plugin, to test | |
| the basic functionality. The test requires the user to | |
| install qdrouterd and the python qpid-proton library in order | |
| to use the simple_recv.py test program. | |
| Thanks to Richard Megginson for the patch. | |
| - omclickhouse bugfix: potential segfault on omclickhouse batchmode | |
| segfault happened when the template did not contain the string | |
| "VALUES". | |
| Thanks to github user wdjwxh for the fix. | |
| - core bugfix: message duplication copied incorrect timestamp | |
| MsgDup() placed timereported into timegenerated property, resulting | |
| in invalid property values. Original timegenerated was lost. This | |
| occurred always when a message needed to be duplicated. Most | |
| importantly this is the case when queues are used. | |
| closes https://github.com/rsyslog/rsyslog/issues/3716 | |
| - core bugfix: segfault on startup depending on queue file names | |
| rsyslog will segfault on startup when a main queue file name has | |
| been set and at least on other queue contains a file name. This | |
| was cased by too-early freeing config error-detection data | |
| structures. It is a regression caused by commit e22fb205a3. | |
| Thanks to Wade Simmons for reporting this issue and providing | |
| detailed analysis. That greatly helps fixing it quickly. | |
| closes https://github.com/rsyslog/rsyslog/issues/3681 | |
| - core "bugfix": alignment issue | |
| This was not a hard error on current platforms, but a | |
| to-be-considered compiler warning regarding invalid alignment. | |
| While it works well on current platforms, alignment issues may | |
| turn into real issues in future platforms. So we try to fix them | |
| if possible. As not only a side-effect this resolves compiler | |
| warnings even on current platforms. | |
| This fix has some regression potential. If so, the problems | |
| may occur during IP address resolution. | |
| see also https://github.com/rsyslog/rsyslog/issues/2608 | |
| - omfile bugfix: potential hang/segfault on HUP of dynafile action | |
| when omfile was HUPed it did not sufficiently clear all dynafile | |
| cache maintenance data structures. This usually lead to misaddressing | |
| and could result in various issues, including a hang of rsyslog | |
| processing or segfaults. It could also have "no effect" by pure | |
| luck of not hitting anything important. This actually seems to | |
| have been the most frequent case. | |
| This seems to be a long-standing bug, but the likelihood of its | |
| appearance seems to have been increased by commit 62fbef7 | |
| introduced in 8.1905. Note: the commit itself has no regression, | |
| just increases the likelihood to trigger the pre-existing bug. | |
| special thanks to Alexandre Guédon for his help in analyzing | |
| the issue - without him, we would probably still not know | |
| what actually went wrong. | |
| closes https://github.com/rsyslog/rsyslog/issues/3686 | |
| - imjournal bugfix: potential message duplication | |
| When journal was preloaded from previously saved cursor it was not advanced | |
| to next entry so reading begun from last message which was therefore | |
| duplicated. | |
| Thanks to Jiri Vymazal for the patch. | |
| - rfc5424 parser bugfix: leading space sometimes lost | |
| if structured data is present a leading space in MSG field is lost | |
| - queue subsystem bugfix: oversize queue warning message shown as error | |
| The warning message was emitted as an error message, which is misleading | |
| and may also break some automated procedures. | |
| - core bugfix: HUP did not work reliable on all platforms | |
| most notably not on FreeBSD, maybe others. The reason was obviously | |
| different handling of signals in respect to multiple threads. | |
| - build system bugfix: missing files in distribution tarball | |
| - testbench | |
| * fixed "make distcheck" settings which were missing some modules | |
| This lead to incomplete "make distcheck" run; some errors were not | |
| detected due to that. | |
| * testbench framework: use ip tool instead of outdated ifconfig | |
| The framework now first checks if "ip" is available and falls back | |
| to "ifconfig" only if this is not the case. | |

| - templates: add datatype template option for JSON generation | |
| The new "datatype" and "onEmpty" template options permits to | |
| generate non-string data rather easily. It works together with | |
| jsonf formatting, which is what people should use nowadays. | |
| closes https://github.com/rsyslog/rsyslog/issues/2827 | |
| - config processing: check disk queue file is unique | |
| If the same name is specified for multiple queues, the queue files | |
| will become corrupted. This commit adds a check during config parsing. | |
| If duplicate names are detected the config parser errors out and the | |
| related object is not created. | |
| Note: this may look to a change-of-behavior to some users. However, | |
| this never worked and it was pure luck that these users did not run | |
| into big problems (e.g. DA queues were never going to disk at the | |
| same time). So it is acceptable to error out in this hard error case. | |

| Introduces the capability to create an output config file that explodes | |
| all "includes" into a single file. This provides a much better overview | |
| of how exactly the configuration is crafted. That could often be a great | |
| troubleshooting aid. | |
| This commit also contains some slight not-really-related cleanup. | |

| - queue subsystem: permit to disable "light delay mark" | |
| New semantic: if lightDelayMark is 0, it is set to the max queue | |
| size, effectively disabling the "light delay" functionality. | |
| Thanks to Yury Bushmelev to mentioning issues related to light | |
| delay mark and proposing the solution (which actually is what | |
| this commit does). | |
| closes https://github.com/rsyslog/rsyslog/issues/1778 | |
| - queue subsystem: provide better user status messages | |
| The queue subsystem now provides additional information messages which | |
| may help a regular user to maintain system health. Most importantly, | |
| DA queues now output when they persist queue data at end of run and | |
| when they restart the queue based on persisted data. | |
| - core: emit a warning message for ultra-large queue size definitions | |
| We see error reports from users who have configured excessively large queues | |
| and receive an OOM condition or other problems. | |
| With that patch we generate a warning message if a queue is configured very | |
| large. "Very large" is defined to be in excess of 500000 messages. | |

| - new global config parameter "internalmsg.severity" | |
| permits to specify a severity filter for internal message. Only | |
| messages with this severity level or more severe are logged. | |
| Originally this was done in rsyslog.conf as usual: you can filter | |
| rsyslog messages on severity, just like any other. But with systemd, | |
| we now emit primarily to the journal, and this is outside of rsyslog's | |
| rule engine and so regular filters do not apply (at least in regard | |
| to the journal). Logging to journal is good, because finally | |
| folks begin to see the messages (traditional distro configs discard | |
| them, for whatever is the reason). | |
| This commit implements a global setting for a severity-based filter | |
| for internal messages, before submitted to journal. So it's not 100% | |
| of what rsyslog can do, but at least some way to customize. | |

| - config processing bugfix: error messages if config.enabled="off" is used | |
| Using config.enabled="off" could lead to error messages on | |
| "parameter xxx not known", which were invalid. They occurred | |
| because the config handler expected them to be used, which | |
| was not the case due to being disabled. | |
| This commit fixes that issue. | |
| closes https://github.com/rsyslog/rsyslog/issues/2520 | |
| - core portability bugfix: harden shutdown processing on FreeBSD | |
| On FreeBSD, rsyslog does not always terminate immediately on SIGTERM. | |
| Root cause seems to be that SIGTERM is delivered differently under | |
| FreeBSD. This causes the main thread to not be awaken, and so it | |
| takes until the next janitor interval to come back to life - which | |
| can be far too long. Fixed this bug explicitly awaking the main | |
| thread. | |
| - imtcp bugfix: oversize message truncation causes log to be garbled | |
| The actual problem is in the tcpserver component. However, the prime user | |
| is imtcp and so users will likely experience this as imtcp problem. | |
| When a too-long message is truncated, the byte after the truncation | |
| position becomes the first byte of the next message. This will garble | |
| the next messages and in almost all cases render it is syslog-noncompliant. | |
| The same problem does NOT occur when the message is split. | |
| This commit fixes the issue. It also includes a testbench fix. | |
| Unfortunately the test for exactly this feature was not properly | |
| crafted and so could not detect the problem. | |

| The flush was only done to the last dynafile in use at end of | |
| transactions. Dynafiles that were also modified during the | |
| transaction were not flushed. | |
| Special thanks to Duy Nguyen for pointing us to the bug and | |
| suggesting a solution. | |

| When first parameter is check_only, the tcpflood funtion shall not | |
| abort the test itself (The fail is intended if this option is set). | |
| closes issue #3625 | |
| - testbench bugfix: imfile-symlink test failed w/ parallel test run | |
| The test sometimes failed. It used a symlink to a hardcoded name | |
| rsyslog-link.*.log. This symlink was created but then disappears. | |
| The reason is that upon (every!) test exit, rsyslog-link.*.log is | |
| deleted. So a parallel test running the exit procedure just at the | |
| "right" time can removed that file. | |
| The bug is that the file name should be created using the tests's | |
| dynamic name. This is done now. | |

| - omelasticsearch: set rawmsg to data from original request | |
| Previously, when constructing the message to submit for a retry | |
| for an original request, if the original request did not contain | |
| the field `message`, the system property `rawmsg` was set to | |
| the entire metadata + data from the original request. This was | |
| causing problems with Elasticsearch. This patch changes | |
| the code so that the `rawmsg` will be set to only the data part | |
| of the original request if there is no `message` field. | |

| Thanks to Nelson Yen for the patch | |
| - core/action: implement capability to resume/suspend via external file | |
| It has been reported that some TCP receivers exists that accept syslog tcp | |
| messages at any rate, even if they do not manage to actually process them. | |
| Instead, they silently drop the message. This behavior is not configurable. | |
| All in all, it can lead to considerate message loss. | |
| To support such use cases, we need to provide an ability to externally | |
| trigger actions suspension and resumption. | |
| We do this via a configured file which contains the status of the action. | |
| Rsyslog periodically reads the file and if it contains "SUSPEND", it | |
| suspend the action (and likewise for resume). | |

| This patch fixes a set of problems plus provides more and enhanced | |
| tests for the module. | |
| Most important problem was a memory leak that occurred when a message | |
| could not be passed at all. For each message that could not be parsed | |
| memory of at least the size the message is leaked. Depending on | |
| traffic pattern this can quickly lead to OOM. Note, however, that | |
| this leak was never reported - it was discovered as part of code | |
| review. | |

| Closes https://github.com/rsyslog/rsyslog/issues/3561 | |
| - imjournal bugfix: Fetching journal cursor only for valid journal | |
| The sd_journal_get_cursor() got called regardless of previous | |
| retcodes from other journal calls which flooded logs with journald | |
| errors. Now skipping the call in case of previous journal call | |
| non-zero result. Fixed success checking of get_cursor() call | |

| - pmdb2diag: create parser module for DB2 diag logs | |
| - TLS subsystem: add support for certless communication | |
| both openssl and GnuTLS drivers have been updated to support certless | |
| communications. In this case e.g. Diffie-Helman is used. | |
| NOTE: this is an insecure mode, as it does NOT guard against | |
| man-in-the-middle attacks. We implemented it because of the large demand, | |
| not because we think it makes sense to use this mode. We strongly recommend | |
| against it. | |

| we now use macros and _Pragma(). This requires less code lines and is more | |
| portable. | |
| - omkafka: add support for dynamic keys | |
| A new configuration property "dynaKey" is added that, when "on", changes the | |
| value of property "key" to a template names instead of a constant value. | |
| This is similar in approach to the DynaTopic implementation. | |
| Thanks to Ludo Brands for the patch. | |
| - AIX port: add AIX linking extensions on many plugins and contributions to | |
| allow building them on this os. | |
| - template: add Time-Related System Property $wday which is the day of week | |

| - imfile bugfix: file reader could get stuck | |
| State file handling was invalid. When a file was moved and re-created | |
| rsyslog could use the file_id if the new file to write the old files' | |
| state file. This could make the file reader stuck until it reached the | |
| previous offset. Depending on file sizes this could never happen AND | |
| would cause large message loss. This situation was timing dependent | |
| (a race) and most frequently occurred under log rotation. In polling | |
| mode the bug was less likely, but could also occur. | |

| STDSQL option added to the default template used in output module of clickhouse | |
| Thanks to gagandeep trivedi for the patch. | |
| - omclickhouse "bugfix": work-around failed error detection | |
| omclickhouse uses a questionable method to check if a request generated | |
| an error. We have seen the method to fail when we slightly upgraded clickhouse | |
| server in CI testing. | |
| This commit makes the method a bit more reliable without really fixing it. | |
| But it's at least a short-term solution. | |
| This should be changed to a proper status check. I assume such is possible. | |

| - imptcp bugfix: overly long socket bind path can lead to segfault | |
| if the `path` input parameter is overly long (e.g. more than 108 | |
| characters on some platforms) a non-terminated string is generated | |

| (very short) in the second phase of the test. It looks like this is | |
| actually a copy&paste error from phase one. Behavior of rsyslog was | |
| correct, but the test itself created a false positive. | |

| - queue: add support for minimum batch sizes | |
| closes https://github.com/rsyslog/rsyslog/issues/495 | |
| - change queue.timeoutshutdown default to 10 for action queues | |
| The previous default of 0 gave action queues no real chance to | |
| shutdown - at the time they were applied, they were usually already | |
| expired (computing the absolute timeout took a small amount of time). | |
| So we change this now to 10ms, which still is very quick but gives | |
| the queue at least a chance to shutdown itself. That in turn | |
| smoothes the whole shutdown process. | |
| If a very large number of action queues is used this may lead | |
| to a very slightly longer shutdown time, albeit this is very | |
| improbable. | |

| [pid 66386] accept(4, {sa_family=AF_INET, sin_port=htons(59054), sin_addr=inet_addr("127.0.0.1")}, [128->16]) = 10 | |
| then, it works a bit with that socket, detects a failure and shuts it down. Sometimes, at the very same instant omfile on another thread tries to open on output file. Then the following happens: | |
| [pid 66386] close(10) = 0 | |
| [pid 66389] openat(AT_FDCWD, "./rstb_356100_31fa9d20.out.log", O_WRONLY|O_CREAT|O_NOCTTY|O_APPEND|O_CLOEXEC, 0644 <unfinished ...> | |
| [pid 66386] close(10 <unfinished ...> | |
| [pid 66389] <... openat resumed> ) = 10 | |
| [pid 66386] <... close resumed> ) = 0 | |
| [pid 66386] poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}], 2, -1 <unfinished ...> | |
| [pid 66389] write(2, "file './rstb_356100_31fa9d20.out"..., 66file './rstb_356100_31fa9d20.out.log' opened as #10 with mode 420 | |
| ) = 66 | |
| [pid 66389] ioctl(10, TCGETS, 0x7f59aeb89540) = -1 EBADF (Bad file descriptor) | |
| This is **literally** from the log, without deleting or reordering | |
| lines. I read it so that there is a race between `open` and `close` | |
| where fd 10 is reused, but seemingly closed - resulting in the `EBADF` | |
| While it smells like a kernel issue, it may be a well-hidden program | |
| bug - if so, one I currently do not find. HOWEVER, this commit | |
| works around the issue by reopening the file when we receive EBADF. | |
| That's the best thing to do in that case, especially if it really is | |
| a kernel bug. Data loss should not occur, as the previous writes | |
| succeeded in that case. | |
| The backdraw of this work-around is that it only "fixes" omfile. In | |
| theory every part of rsyslog can be affected by this issues (queue | |
| files, for example). So this is not to be considered a final solution | |
| of the root issues (but a big step forward for known problem cases). | |

| - omhttp bugfix: segfault due to NULL pointer access | |
| many thanks to Gerardo Puerta for the patch | |
| - omkafka bugfix: segfault when running in debug mode using dynamic topics | |
| This should only affect test environments, as debug mode is not | |
| suitable for production (and really does not work when running for | |
| extended period of time). | |
| - testbench bugfix: TLS syslog tests for "anon" mode were broken | |
| They did not detect when "anon" mode was not properly supported by the | |
| drivers. | |
| - test tooling bugfix: correct tcpflood error messages | |
| it looks like tcpflood's openssl code stems partly back to tcpdump, at | |
| least the error messages indicate this. Thankfully tcpdump is BSD licensed, | |
| so this should not be a big issue. Nevertheless, the incorrect program name | |
| in error messages needs to be corrected, and this is what this commit does. | |
| - tcpflood bugfix: tool did not terminate on certificate error | |
| when tcpflood detected a certificate error, it reported an | |
| error message but did not abort. This could make errors undetectable | |
| during CI runs. | |
| also fix tests which did not properly provide CA cert (which than | |
| caused the error). | |
| - testbench: fix issues with journal testing | |
| The configure/Makefile checks were not correct, leading to the | |
| build of journal components when not necessary, even if not | |
| supported by the platform. Thus lead to invalid build and test | |
| failures. | |
| - testbench: add tests for "certless" tcp/tls | |
| This adds a test to ensure that a client without certificate can | |
| connect to a server with certificates. So it is not exactly | |
| "certless". | |
| The prime intent of this test is to match config suggestions given | |
| by log hosting companies (like loggly) and so ensure that we do | |
| not accidentally break them. This is especially important as the | |
| capability for certless clients was not properly documented and | |
| also become forgotten by the rsyslog team. | |

| - CI | |
| - further improve testbench robustness against slow machines | |
| - testbench: add tests for parser.EscapeControlCharacterTab global option | |
| - testbench: Updated all expired x.509 certs | |
| Closes https://github.com/rsyslog/rsyslog/issues/3348 | |
| - fix a potential race in CI debug mode which can lead to segfault | |
| only when instructed to do so, rsyslog may emit a "final worker thread shutdown" | |
| messages. This is usually only enabled in CI and/or other testing. If enabled, | |
| the code has a race on the pWti object which can lead to segfault or abort. | |
| Only system which explicitly enable this CI aid are affected (running in debug | |
| mode alone is NOT sufficient). | |
| This is a regression from 8.40.0. | |
| - testbench: improve robustness against slow CI, gen. improvements | |
| * add an overall timeout value for tests - if running longer, | |
| testbench framework tries to FAIL and end test. Note that | |
| this is not bullet-proof and not intended to be so. | |
| * guard against hanging rsyslog instances via a new imdiag | |
| feature to abort after n number of seconds; among others, | |
| this guards as against timeout-cancel in CI, which is always | |
| pretty hard to diagnose - now we see these errors in test-suite.log | |
| * fix a bug in tcp zip test, which actually did not use zip mode | |
| * experimentally add debug output to better understand | |
| shutdown_when_empty operation; goal is to improve understanding | |
| and then remove that code again. | |
| * improve shutdown predicate for a couple of tests | |
| * made travis run make check with two parallel threads, for which | |
| we seem ready now. Nevertheless, it's still experimental and we | |
| may roll this back if required. | |
| * testbench: disable omprog tests that hang under coverage instrumentation | |
| When gcc coverage instrumentation is used, these tests hang. They work | |
| with clang coverage instrumentation, but for some reason clang does not | |
| give us full reports (at least not when used together with CodeCov.io). | |
| We have tried to troubleshoot this for hours and hours - now is time to | |
| give up until someone comes up with a bright idea. So we make the affected | |
| tests skip themselves when they detect gcc with coverage instrumentation. | |
| * testbench: add new test for imfile and logrotate in copytruncate mode | |
| * testbench: add new omkafka tests for dynamic topics | |
| * travis: do no longer run 0mq tests | |
| This often causes trouble when the packages are rebuild by the 0mq project | |
| (which happens frequently). We already do intensive testing of the 0mq | |
| components in the buildbot infrastructure, where we use dedicated containers. | |
| This is reliable, as the containers already contain everything needed and so | |
| do not need to reach out to the 0mq package archives. In the light of this, | |
| let's save us the trouble of Travis failures. The only downside is that | |
| users cannot pre-test with their local Travis when modifying 0mq modules, | |
| which is quite acceptable. | |

| Version 8.40.0 [v8-stable] 2018-12-11 | |
| - mmkubernetes: add support for sslpartialchain for openssl | |
| If `"on"`, this will set the OpenSSL certificate store flag | |
| `X509_V_FLAG_PARTIAL_CHAIN`. This will allow you to verify the Kubernetes API | |
| server cert with only an intermediate CA cert in your local trust store, rather | |
| than having to have the entire intermediate CA + root CA chain in your local | |
| trust store. See also `man s_client` - the `-partial_chain` flag. | |
| This option is only available if rsyslog was built with support for OpenSSL and | |
| only if the `X509_V_FLAG_PARTIAL_CHAIN` flag is available. If you attempt to | |
| set this parameter on other platforms, you will get an `INFO` level log | |
| message. This was done so that you could use the same configuration on | |
| different platforms. | |
| - openssl driver: improved error messages | |
| also fixes misleading wording of some error messages | |
| closes https://github.com/rsyslog/rsyslog/issues/3238 | |
| - imfile: disable file vs directory error on symlinks | |
| The file/directory node-object alignment now ignores symlinks. Previously | |
| it reported error on each directory symlink spamming user error logs. | |
| Thanks to Jiri Vymazal for the patch. | |
| - cleanup: remove no longer needed --enable-rtinst code | |
| configure option --enable-rtinst is gone-away since a while, but there were | |
| still some supporting code left. It required careful analysis what could | |
| actually be removed. This is now done and the code fully cleaned up. This | |
| greatly simplifies the code and also makes it better readable for | |
| developers which are not deep inside the rsyslog code base. | |
| As a positive side effect, we could eliminate mutex calls inside | |
| the debug system. This means we are more likely to reproduce race | |
| conditions in runs with debugging enabled. | |
| closes https://github.com/rsyslog/rsyslog/issues/2211 | |
| - bugfix imfile: rsyslog re-sends data for files larger 2GiB | |
| This occurs always if and only if | |
| - reopenOnTruncate="on" is set | |
| - file grows over 2GiB in size | |
| Then, the data is continuously re-sent until the file becomes smaller | |
| 2GiB (due to truncation) or is deleted. | |
| It is a regression introduced by 2d15cbc8221e385c5aa821e4a851d7498ed81850 | |
| closes https://github.com/rsyslog/rsyslog/issues/3249 | |
| - config: fix segfault in backticks "echo" expansion of undefined variables | |
| The bug was introduced in commit abe0434 (config: enhance backticks "echo" | |
| capability). The getenv() result passed to strlen() and es_addBuf() may be | |
| NULL if the environment variable does not exist, resulting in a segfault. | |
| Thanks to Julien Thomas for the patch. | |
| fixes https://github.com/rsyslog/rsyslog/issues/3006 | |
| - bugfix imsolaris: message timestamps on Solaris | |
| On Solaris messages don't have their time directly in the raw body but in | |
| a separate log_ctl structure which is currently not used. | |
| When message is logged and processed, rsyslogd gives it current time because | |
| it ignores the actual one. That means that old messages (e.g. from system | |
| reboot) get timestamp of processing instead of the reboot itself (it is | |
| not a problem for live logging where now is used anyway). | |
| Thanks to Jakub Kulik for the patch. | |
| - bugfix build system: "make distcheck" did not work for mysql tests | |
| - bugfix build system: don't link liblogging-stdlog when available but not enabled | |
| When liblogging-stdlog was available but configure option "--disable-liblogging-stdlog" | |
| was set, rsyslog was still linking against liblogging-stdlog. | |
| This commit will ensure that rsyslog will only link against liblogging-stdlog when | |
| "--enable-liblogging-stdlog" was set. | |
| see also: https://bugs.gentoo.org/667836 | |
| - bugfix RainerScript: abs() could return negative value, now in range [0..max] | |
| Thanks to Harshvardhan Shrivastava for providing the patch | |
| - bugfix debug output: date property options output wrongly | |
| inside debug logging, the date property options were not all | |
| properly converted into strings. Some of the newer ones were | |
| invalidly flagged as "UNKNOWN". This is primarily a cosmetic | |
| problem and has no effect other than puzzling folks looking at | |
| the debug log. | |
| - bugfix omhttp: did not compile on some platforms | |
| - CI | |
| * made mysql-based tests (ommysql and omlibdbi) work inside containers | |
| * bugfix testbench: do not execute libgcrypt tests if disabled | |
| closes https://github.com/rsyslog/rsyslog/issues/3228 | |
| * testbench: grep failed when string starting with "-" was used | |
| The search term was mistakenly interpreted as an option. | |
| * testbench: support auto-start/-stop of mysqld | |
| This is required to run mysql/mariadb tests inside containers. | |
| closes https://github.com/rsyslog/rsyslog/issues/3223 | |
| * improve bash coding style and fix a some bug in testbench | |
| - duplicate diag.sh init call was not detected due to typo | |
| - queue-persists test did not work correctly | |
| - some general testbench framework improvements | |
| issues found be shellcheck, fixes brought up other work to do | |
| * testbench: improve journal tests and testbench framework | |
| improving both style and reliability of journal tests; along that way | |
| also improve testbench framework: | |
| - do cleanup on error_exit and skip | |
| - explicit skip handler (vs exit 77) | |
| this permits us to do better cleanup | |
| - new testbench functions for journal-specific functionality | |
| reduce code duplication and make things easier to maintain in the | |
| future | |
| - provide a way to do valgrind and non-valgrind tests with a single | |
| test file | |
| see also https://github.com/rsyslog/rsyslog/issues/2564 | |
| * testbench: improve framework, harden rscript http test | |
| - the test now tries to detect unavailable http server, which | |
| should not result in test failure | |
| - equivalent valgrind test changed to new method, removing code | |
| duplication | |
| - testbench supports | |
| * new exit code 177, which indicates environment error, makes | |
| test SKIP but still reports the failure | |
| * new exitcode, logurl stats reporting fields | |
| * report buildbot builder (if provided) in failure report | |
| * testbench: add test for mmjsonparse with unparsable data | |
| * testbench: make es-bulk-retry test more reliable | |
| We now no longer depend on a fixed 'sleep' command but rather | |
| check the output file for what we expect. This is much more | |
| robust on slow test machines. | |
| We believe this closes the below-mentioned issue. If not, it | |
| should be re-opened. | |
| closes https://github.com/rsyslog/rsyslog/issues/3104 | |
| * testbench: suppress valgrind error caused by pthreads lib | |
| finally I give up and honestly think this is a problem in pthreads and | |
| not in rsyslog code. See issue below and previous commit for more | |
| information. | |
| Unfortunately, this will also mask off cases where we do not properly | |
| call pthread_join() albeit it is needed. Nevertheless, this bug is | |
| causing so much CI grief that it is definitely worth it. | |
| closes https://github.com/rsyslog/rsyslog/issues/2902 | |
| * testbench: made a couple of (unnamed due to too many) test more robust | |
| against slow (CI) machines | |
| ------------------------------------------------------------------------------ | |
| Version 8.39.0 [v8-stable] 2018-10-30 | |
| - imfile: improve truncation detection | |
| previously, truncation was only detected at end of file. Especially with | |
| busy files that could cause loss of data and possibly also stall imfile | |
| reading. The new code now also checks during each read. Obviously, there | |
| is some additional overhead associated with that, but this is unavoidable. | |
| It still is highly recommended NOT to turn on "reopenOnTruncate" in imfile. | |
| Note that there are also inherent reliability issues. There is no way to | |
| "fix" these, as they are caused by races between the process(es) who truncate | |
| and rsyslog reading the file. But with the new code, the "problem window" | |
| should be much smaller and, more importantly, imfile should not stall. | |
| see also https://github.com/rsyslog/rsyslog/issues/2659 | |
| see also https://github.com/rsyslog/rsyslog/issues/1605 | |
| - imjournal: work around journald excessive reloading behavior | |
| This is workaround for possible imjournal interaction with systemd | |
| where journal invalidate fix is not present. The code tries to | |
| detect SD_JOURNAL_INVALIDATE loop and not reload after each call. | |
| Thanks to Jiri Vymazal for the patch. | |
| - errmsg: remove no longer needed code | |
| refactored code (over a long time) so that object-ish style is no longer | |
| needed and could now finally be removed; We also refactored the last | |
| component (omhttp contrib module) that used the old interface. | |
| closes https://github.com/rsyslog/rsyslog/issues/1684 | |
| - queue bugfix: invalid error message on queue startup | |
| due to some old regression (commit not exactly identified, but for | |
| sure a regression, 9 years ago it was correct) an error message | |
| is emitted when no .qi file exists on startup of the queue, which | |
| is a normal condition. | |
| Actually, the code should not have tried to open the .qi file in | |
| the first place because it detected that it did not exist. That | |
| (necessary) shortcut had been removed a while ago. | |
| closes https://github.com/rsyslog/rsyslog/issues/3117 | |
| - bugfix imrelp: regression with legacy configuration startup fail | |
| Startup of a relp listener failed if legacy configuration was used. | |
| caused by commit: 32b71daa8aadb8f16fe0ca2945e54d593f47a824 | |
| closes https://github.com/rsyslog/rsyslog/issues/3106 | |
| - bugfix imudp: stall of connection and/or potential segfault | |
| There was a regression in 493279b790a8cdace8ccbc2c5136985e820dd2fa. | |
| This regression may cause stop (or delay) of reception from some systems | |
| and may also cause a segfault. Triggering condition is that at least | |
| one listener could not be created. | |
| Thanks to Jens Låås for the patch. | |
| - bugfix gcry crypto driver: small memleak | |
| If a crypto key is specified directly via the key="" parameter, | |
| the storage for that key is not freed, causing a small memleak. | |
| Note that the problem occurs only once per context, so this | |
| should not cause real issues. Even more so, as specifying a | |
| key directly is meant only for testing purposes and is strongly | |
| discouraged for production use. | |
| Detected by internal testing, no actual fail case known. | |
| - fix potential misaddressing in encryption subsystem | |
| could happen if e.g. disk queues were encrypted | |
| not seen in practice but caught by testbench test | |
| - ksi subsystem changes | |
| * enhance debug logging | |
| * disable unsafe SHA1 algorithm | |
| Thanks to Allan Park for the patch. | |
| - bugfix core: regex compile error messages could be incorrect | |
| - bugfix core: potential hang on rsyslog termination | |
| The root cause was a deadlock during worker startup. This could | |
| happen for example when a DA queue needed to persist data during | |
| shutdown. | |
| Fail condition: | |
| * startup request for a new worker | |
| * initialization of that worker | |
| * immediate detection that the worker can or must shutdown | |
| * main thread waiting for worker running state, which it skips, | |
| and so the main thread hangs inside a loop | |
| closes https://github.com/rsyslog/rsyslog/issues/3094 | |
| - bugfix imkafka: system hang when backgrounded | |
| imkafka initializes librdkafka too early (before the fork). This leads | |
| to hangs in various parts of the system - not only im imkafka but | |
| other functions as well (e.g. getaddrinfo() calls). | |
| closes https://github.com/rsyslog/rsyslog/issues/3180 | |
| - bugfix imfile: file change was not reliably detected | |
| A change in the inode was not detected under all circumstances, | |
| most importantly not in some logrotate cases. | |
| Includes new tests made by Andre Lorbach. They now use the | |
| logrotate tool natively to reproduce the issue. | |

| closes https://github.com/rsyslog/rsyslog/issues/3025 | |
| - bugfix core/debug: data written to random fd 2 under some debug settings | |
| This happens only during auto-backgrounding, where we cannot any longer | |
| access stderr. Whatever is opened with fd2 receives some debug messages. | |
| Note that the specific feature is usually turned on only in CI runs. | |
| - cleanup: removed no longer needed code | |
| Code that was unused for quite a while or did not really belong to the | |
| project identified and removed. | |
| - overall code cleanup | |
| e.g. remove unused code, replace bad bash constructs, etc... | |
| - CI: | |
| * some small improvements in testbench plumbing | |
| e.g. (`cmd` replaced by $(cmd), removed useless use of cat, ...) | |
| * testbench: improve plumbing for kafka tests | |
| - Removed all sleeps where possible. | |
| - Moved all kafka start/stop/download logic into functions. | |
| - Moved kafka/zookeeper stop into error_exit and exit_test. | |
| - Kafka/Zookeeper cleanup only done on success now. | |
| - Kafka/Zookeeper logfiles automatically dumped on error_exit only now. | |
| - Added cleanup for Kafka/Zookeeper instances into CI/buildbot_cleanup.sh | |
| - added new tests | |
| * testbench: fix incompatibility of one omprog test with Python3 | |
| Python3 writes to stderr immediately, and this caused the | |
| captured output to differ with respect to Python2. Simplified | |
| the test to do a single write to stderr. Also a cast to int | |
| was needed when calculating 'numRepeats'. | |
| closes https://github.com/rsyslog/rsyslog/issues/3030 | |
| * testbench: fixed imfile parallel issues | |
| - Fixed timing issues in some imfile wildcard/regex tests | |
| - Added touch command in imfile wildcard tests to make sure directories | |
| exist before files are created in it if IO is under stress. | |
| - changed content checking in some tests to use "content_check_with_count" | |
| with check timeouts instead of using fixed sleeptimes. | |
| * testbench: new basic tests | |
| These ensure that for some modules that did not have any tests at all | |
| we have at least a minimal coverage (module loads, activates, is able | |
| to emit error messages). Of course, further improvements would make | |
| much sense. Modules: | |
| - ommail | |
| - testbench: new tests for disk queue encryption | |
| - testbench: improved auto-diagnostics for hanging instance | |
| - testbench: hardened kafka test against failing kafka subsystem, | |
| not in 100% of the cases, but at least in some that frequently occur | |
| - failing tests now report failure status so that we can get stats | |
| on unreliable tests | |
| - testbench tooling: fix incorrect tcpflood TLS parameter check | |
| could lead to segfault when started | |
| - bugfix testbench tooling: tcpflood invalid type in calloc (openssl mode) | |
| It is unlikely that this has caused a real issue, as long as pointers | |
| are all of the same size (what is highly probable). | |

| Version 8.38.0 [v8-stable] 2018-09-18 | |
| - AIX: make basic modules work again | |
| - make rsyslog build on AIX again | |
| ... at least for a limited set of default modules | |
| - imfile: support for endmsg.regex | |
| This adds support for endmsg.regex. It is similar to | |
| startmsg.regex except that it matches the line that denotes | |
| the end of the message, rather than the start of the next message. | |
| This is primarily for container log file use cases such as this: | |
| date stdout P start of message | |
| date stdout P middle of message | |
| date stdout F end of message | |
| The `F` means this is the line which contains the final part of | |
| the message. The fully assembled message should be | |
| `start of message middle of message end of message`. | |
| `startmsg.regex="^[^ ]+ stdout F "` will match. | |
| Thanks to Richard Megginson for the patch. | |
| - imkafka: add parameter "parseHostName" | |
| This enables imkafka to parse the hostname from log message. | |
| Previously that was not possible. It was most likely a bug, but | |
| one that users may count on. The new parameter "ParseHostName" | |
| (default is off) controls this behavior. Default is to NOT | |
| parse the hostname. | |
| Thanks to github user snaix for the contribution. | |
| - im[p]tcp: improve error message on connect failure | |
| Now a message with the actual OS error is emitted, making things far | |
| easier to troubleshoot. | |
| - imkafka: implement multithreading support for kafka consumers. | |
| Each consumer runs in it's own consumer thread now. New tests have also | |
| been added for this. | |
| - omelasticsearch: write all header metadata to $.omes for retries | |
| Write all of the original request metadata fields to $.omes for | |
| the retry, if present. This may include all of the following: | |
| _index, _type, _id, _parent, pipeline | |
| This is in addition to the fields from the response. If the same | |
| field name exists in the request metadata and the response, the | |
| field from the request will be used, in order to facilitate | |
| retrying the exact same request. | |
| Thanks to Richard Megginson for the patch. | |
| - core: improve error message on module load fail | |
| The error message now lists all dlopen() errors in depth. This is | |
| especially useful if the error is due to missing symbols or file | |
| format errors. | |
| - core/queue: add error message if queue file cannot be accessed | |
| When having a disk-assisted queue without permission to write to the specified | |
| queue file an error will now be generated. | |
| closes https://github.com/rsyslog/rsyslog/issues/323 | |

| - omprog: add feedback timeout and keep-alive feature | |
| - Restart the program if it does not respond within timeout. | |
| - New setting 'confirmTimeout' (default 10 seconds). | |
| - Allow the program to provide keep-alive feedback when a | |
| message requires long-running processing. | |
| - Improve efficiency when reading feedback line (use buffer). | |
| Retry interrupted writes/reads to/from pipe. | |
| - New setting 'reportFailures' for reporting error messages | |
| from the program. | |
| - Report child termination when writing to pipe. | |
| - Minor refactor: renamed writePipe function to sendMessage, | |
| renamed readPipe to readStatus. | |
| Thanks to Joan Sala for contributing this. | |
| - omprog: fix forceSingleInstance configuration option | |
| The forceSingleInstance option did not work as intended. Even | |
| if set multiple instances were spawned. This most probably | |
| was a regression from 0453b1670fc34c96d31ee7c9a370f0f5ec24744a | |
| The code was broken roughly 3.5yrs ago, so it looks like the | |
| issue was little-noticed. This also means that potentially some users | |
| may see the bugfix as change of behavior. If so, just remove | |
| the option. | |

| - imfile: implement file-id, used in state file | |
| This ensures that files with the same inodes are not accidentally treated | |
| as equal, at least within the limits of the file id hash (see doc for | |
| details). | |
| We use the siphash reference implementation to generate our non-cryptographic | |
| hash. | |

| - core: emit TZ warning on startup not on Linux non-container | |
| On Linux it seems common that the TZ variable is NOT properly set. | |
| There are some concerns that the warning related to rsyslog correcting | |
| this confuses users. It also seems that the corrective action rsyslog | |
| takes is right, and so there is no hard need to inform users on that. | |
| In Linux containers, however, the warning seems to be useful as the | |
| timezone setup there seems to be frequently-enough different and | |
| rsyslog's corrective action may not be correct. | |
| So we now check if we are running under Linux and not within a container. | |
| If so, we do not emit the warning. In all other case, we do. This is | |
| based on the assumption that other unixoid systems still should have | |
| TZ properly set. | |

| - omkafka: | |
| * better debug information | |
| * Fixed minor issue in omkafka producing wrong kafka timestamps when | |
| msgTimestamp was NULL. | |
| * Setting RD_KAFKA_V_KEY(NULL, 0) in rd_kafka_producev now when KEY is not | |
| configured. | |
| * Fixed minor issue when rsyslog is compiled with --enable-debug and | |
| librdkafka is too old. | |

| - mmkubernetes: action fails preparation cycle if kubernetes API ... | |
| ... destroys resource during bootup sequence | |
| The plugin was not handling 404 Not Found correctly when looking | |
| up pods and namespaces. In this case, we assume the pod/namespace | |
| was deleted, annotate the record with whatever metadata we have, | |
| and cache the fact that the pod/namespace is missing so we don't | |
| attempt to look it up again. | |
| In addition, the plugin was not handling error 429 Busy correctly. | |
| In this case, it should also annotate the record with whatever | |
| metadata it has, and _not_ cache anything. By default the plugin | |
| will retry every 5 seconds to connect to Kubernetes. This | |
| behavior is controlled by the new config param `busyretryinterval`. | |
| This commit also adds impstats counters so that admins can | |
| view the state of the plugin to see if the lookups are working | |
| or are returning errors. The stats are reported per-instance | |
| or per-action to facilitate using multiple different actions | |
| for different Kubernetes servers. | |
| This commit also adds support for client cert auth to | |
| Kubernetes via the two new config params `tls.mycert` and | |
| `tls.myprivkey`. | |
| Thanks to Richard Megginson for the patch. | |
| - bugfix pmnormalize/core: several memory leaks, invld property handling | |
| - major memory leak which occurred once per message processed | |
| So this could lead to OOM. Caused by improper free of json | |
| structure | |
| - another two major leaks of similar magnitude could occur if | |
| "fromhost-ip" and/or "fromhost" properties were set | |
| - minor leaks upon termination. these were unproblematic as | |
| static and only occurred immediately before shutdown. | |
| But they triggered memory debugger errors. | |
| - fixed test which did not check for mem leaks albeit it should | |
| - core invalid handling of the "fromhost" property, if set via | |
| the MsgSetPropsViaJSON() call. This was primarily of concern | |
| for pmnormalize and mmexternal, and only if these properties | |
| were used by either the rulebase or the external program | |
| response. | |
| Actually, most of the leaks go back to rsyslog core, but that | |
| core functionality was not used by other modules in the same | |
| way. But if some other would have used it, the effects would | |
| have been the same (so be aware if you wrote custom modules). | |
| - bugfix imptcp: fixed pointers for session counting | |
| imptcp open, failedopen, and closed pstats counters were assigned the wrong | |
| name, thus pstats values did provide a totally wrong picture of what was | |
| going on. | |
| Thanks to github user jeverakes for the patch. | |
| - bugfix omprog: invalid memory access on partial writes to pipe | |
| When sending logs to the program, in case of a partial write to the pipe, | |
| invalid data was sent, or an invalid memory access could occur. (A | |
| partial write can occur if the syscall is interrupted or the pipe is full.) | |
| Thanks to Joan Sala for contributing this. | |
| - bugfix omprog: rsyslog's environment was not passed to script | |
| closes https://github.com/rsyslog/rsyslog/issues/2921 | |
| - bugfix omprog: severity of some log messages in waitForChild corrected | |
| Log some messages related to child process termination as info/warn | |
| instead of error. | |
| - bugfix imfile: files which were loaded via symlink were not always followed | |
| They were stopped watching after being rotated. | |
| closes https://github.com/rsyslog/rsyslog/issues/2229 | |
| Thanks to Jiri Vymazal for the patch. | |
| - bugfix imfile: potential misaddressing when processing symlinks | |
| Fixed parent name when processing symlinks. Detected during code review. | |
| There was a garbage byte left before which could cause errors down the | |
| road. | |
| Thanks to Jiri Vymazal for the patch. | |
| - bugfix ommongodb: build issue if mongo-c-driver is not compiled with TLS | |

| - CI: | |
| * many changes with the goal to support parallel test execution, e.g. | |
| use dynamic ports and file names, changes to testing tools, etc. | |
| * kafka tests re-enabled, as they should now no longer be racy. However, | |
| this has yet to be proven in practice. | |
| * upgrading kafka server version to current | |
| * Fixed server configuration issues holding the kafka tests back from working | |
| * Fixed some config issues in all sndrcv kafka tests. | |
| * Generating dynamically kafka topics now for each kafka test. | |
| * Reenabled kafka_multi test which runs a test on 3 kafka/zookeeper instances | |

| Version 8.37.0 [v8-stable] 2018-08-07 | |
| - build system: add --enable-default-tests ./configure option | |
| This permits to control the "default tests" in testbench runs. These | |
| are those tests that do not need a special configure option. There are | |
| some situations where we really want to turn them of so that we can | |
| run tests only for a specific component (e.g. ElasticSearch). | |
| This commit also removes the --enable-testbench[12] configure switches, | |
| which were introduced just to work-around travis runtime restrictions. | |
| With the new CI setup and new options we could reduce the Travis runtime | |
| dramatically and so we do not need them any longer. | |
| - overall adaptation to gcc 8 which emits new warnings | |
| - fix some build warnings on 32bit systems, namely armhf architecture | |
| - ommail change of behavior: "enable.body" default now "on" | |
| This was always documented to be "on", but actually was "off". Usually, we | |
| fix the doc, but after long discussion the agreement was that in this | |
| specific case it was actually better to change the default. | |
| see also: https://github.com/rsyslog/rsyslog/pull/2791 | |
| - core/omfile: race in async writing mode | |
| mutex was not properly locked at all times when the async writing buffer | |
| was flushed | |
| Thanks to Radovan Sroka for the patch. | |
| - core: provide a somewhat better default action name | |
| We now include the module name (e.g. "omelasticsearch" or "builtin:omfile") | |
| as part of the name. This is still not perfect, but hopefully a bit | |
| easier to grasp. | |
| see also https://github.com/rsyslog/rsyslog/issues/342 | |
| - new global() parameter "abortOnUncleanConfig" | |
| This provides a new-style alternative to $AbortOnUncleanConfig. | |
| closes https://github.com/rsyslog/rsyslog/issues/2744 | |
| - tcpflood no longer links with -lgrcypt | |
| as this is no longer necessary for GnuTLS | |
| Thanks to Michael Biebl for the patch. | |
| - imjournal: add journal-specific impstats counters | |
| these provide some additional insight into journal operations | |
| Thanks to Abdul Waheed for the patch. | |
| - imjournal: fixed startup on missing state file | |
| When starting rsyslog with imjournal for first time it outputs | |
| an error and plugin does not run because no state file exists yet. | |
| Now it skips the loading and creates state file on first persist. | |
| Thanks to Jiri Vymazal for the patch. | |
| - imjournal: fetching cursor on readJournal() and simplified pollJournal() | |
| Fetching journal cursor in persistJournal could cause us to save | |
| invalid cursor leading to duplicating messages further on, when new | |
| WorkAroundJournalBug option is set we are saving it on each | |
| readJournal() where we now that the state is good. | |
| pollJournal() is now cleaner and faster, correctly handles INVALIDATE | |
| status from journald and is able to continue polling after journal | |
| flush. Also reduced POLL_TIMEOUT a bit as it caused rsyslog to exit | |
| with error in corner cases for some ppc when left at full second. | |
| re-factored imjournal CI tests with journal_print tool to have more | |
| detailed error reporting. | |
| Thanks to Jiri Vymazal for the patch. | |
| - config: enhance backticks "echo" capability | |
| This is now more along the lines of what bash does. We now support | |
| multiple environment variable expansions as well as constant text | |
| between them. | |
| example: | |
| env SOMEPATH is set to "/var/log/custompath" | |
| config is: param=`echo $SOMEPATH/myfile` | |
| param than is expanded to "/var/log/custompath/myfile" | |
| among others, this is also needed inside the testbench to properly | |
| support "make distcheck". | |
| Note: testbench tests follows via separate commit. There will be | |
| no special test, as the testbench itself requires the functionality | |
| at several places, so the coverage will be very good even without | |
| a dedicated test. | |
| - imrelp: add support for setting address to bind to (#894) | |
| This adds a new optional `address` parameter to `imrelp` inputs in order | |
| to specify an address to bind to. | |
| Based on support added by rsyslog/librelp@96eb5be | |
| Thanks to Simon Wachter for the patch. | |
| - omrelp: permit all authmodes; updated tests | |
| omrelp for some time limited authentication modes to those | |
| that were known. While this was OK, it prevented the easy | |
| introduction of new auth modes into librel. | |
| This has now been changed; omrelp now checks the validity of | |
| the authmode directly via librelp by doing some librelp calls | |
| upon processing the configuration. | |
| Also, some tests have been updated to check this feature and | |
| also ensure that the new librelp mode "certvalid" works | |
| (if it is available). | |
| - regexp.c: reduce lock contention when using glibc. | |
| When using glibc, we enable per-thread regex to avoid lock contention. | |
| See: | |
| - https://github.com/rsyslog/rsyslog/issues/2759 | |
| - https://github.com/rsyslog/rsyslog/pull/2786 | |
| - https://sourceware.org/bugzilla/show_bug.cgi?id=11159 | |
| This should not affect BSD as they don't seem to take a lock in regexec. | |
| NOTE: it is assumed that we can craft an even better solution than | |
| this patch, but it improves the situation and we do not have time to | |
| craft more. So we decided to merge. For details see | |
| https://github.com/rsyslog/rsyslog/pull/2786 | |
| - mmpstrucdata: better error message, support $! in var names | |
| see also https://github.com/rsyslog/rsyslog/issues/1262#issuecomment-404773495 | |
| - more explicit error msg with message modification mod on queue | |
| Message modification modules do not work if used with a non-direct queue. | |
| We now make this more explicit in the config parsing error message. | |
| closes https://github.com/rsyslog/rsyslog/issues/1323 | |
| - omrabbitmq: improve high-load performance | |
| A different pthread mutex is created for each connection (action) | |
| instead of a single one shared by all connections. This will | |
| improve performance when using multiple concurrent connections | |
| to a single (or multiple) RabbitMQ instance(s) (e.g. for load balancing) | |
| Thanks to github user micoq for contributing the patch. | |
| - imudp: replace select() calls by poll() | |
| This improves reliability in extreme cases (more than 1024 fds open when | |
| imudp begins to listen) and potentially improves performance a little. | |
| - ommysql: support mysql unix domain socket: | |
| via action(.. socket="/tmp/mysqld.sock" ..) | |
| Thanks to JoungKyun Kim for contributing this. | |
| - impstats: emit warning if log.syslog="off" and ruleset name given | |
| With this config, "ruleset" is silently ignored, what probably is | |
| not obvious to a user. | |
| closes https://github.com/rsyslog/rsyslog/issues/2821 | |
| - build system cleanup: remove no longer needed --enable-memcheck | |
| This was used for a very old testing capability, no longer functional but | |
| causes build to fail if enabled. Replaced by ASAN/valgrind. | |
| Issue detected while testing some other CI settings. | |
| - tools: Updated python based statslog analyzer sample scripts | |
| - developer tools: make devcontainer tool more developer friendly | |
| slight improvement for easy interactive use | |
| - enable better testing via "make distcheck" | |
| Also a couple of changes to testbench worth mentioning: | |
| * use cp -f to ensure files can be overwritten in VBUILD | |
| * fix issue of missing include test file in EXTRA_DIST | |
| * new suppressions | |
| * testbench: try to use local system dependency cache | |
| avoid going to Internet repos if not absolutely necessary. For | |
| development containers, they should be pre-populated with the | |
| important dependencies. | |
| * do not enable libfaketime if ASAN is selected | |
| unfortunately, libfaketime does not work in that case | |
| Note: for modules with non-standard dependencies (e.g. databases), | |
| "make distcheck" only enables what on the original ./configure line | |
| was enabled. This is done in order to ensure that "distcheck" adapts | |
| to what is actually available on the system in question. Rsyslog's | |
| own CI system installs the maximum set of possible dependencies and | |
| so tries the maximum set "make distcheck" can support on a platform. | |
| see also https://github.com/rsyslog/rsyslog/issues/174 | |
| - add new global config parameter "inputs.timeout.shutdown" | |
| - omusrmsg: do not fall back to max username length of 8 | |
| This happens if utmp.h and friends are not available and stems back to | |
| the original syslogd. Nowadas, 32 is more appropriate and now being used | |
| in that (now very unlikely) case. The detection logic for UT_NAMESIZE has | |
| also been streamlined. | |

| - bugfix build system: fix race in parallel builds | |
| If libgcry.la is built later than lmcry_gcry.la, there is a failure: | |

| |make[2]: *** [lmcry_gcry.la] Error 1 | |
| [snip] | |
| The LIBADD of lmcry_gcry.la contains libgcry.la, we should also add libgcry.la | |
| to lmcry_gcry.la's DEPENDENCIES. | |
| Thanks to Hongxu Jia for the patch. | |
| - bugfix imfile: memory leak upon shutdown (cosmetic) | |
| When rsyslog shuts down and imfile is inside a change polling loop, | |
| it does not properly free memory returned by glob(). This is a cosmetic | |
| bug as the process terminates within the next few milliseconds. However, | |
| it causes memory analyzer reports and thus makes CI fail. | |
| - bugfix core msg: potential deadlock (and rsyslog hang) | |
| can happen e.g. with headerless messages when app-name | |
| property is used | |
| closes https://github.com/rsyslog/rsyslog/issues/3135 | |
| - bugfix core: do not abort startup on problems setting scheduling policy | |
| rsyslog creates a default scheduling policy on startup. This code | |
| invalidly used CHKiRet (our exception handler) to check pthreads | |
| return codes, what this macro cannot do. This lead to hard to | |
| diagnose startup problems in cases where there were problems | |
| setting the scheduling defaults (e.g. when rsyslog is set to run | |
| at idle priority). Even more so, this blocked startup altogether, | |
| which is not the right thing to do. Actually, this can be considered | |
