Changes with Apache 2.3.9
*) mod_cache: Add a discrete commit_entity() provider function within the
mod_cache provider interface which is called to indicate to the
provider that caching is complete, giving the provider the opportunity
to commit temporary files permanently to the cache in an atomic
fashion. Move all "rename" functionality of temporary files to permanent
files within mod_disk_cache from ad hoc locations in the code to the
commit_entity() function. Instead of reusing the same variables for
temporary file handling in mod_disk_cache, introduce separate discrete
structures for each of the three cache file types, the headers file,
vary file and data file, so that the atomic rename of all three file
types within commit_entity() becomes possible. Replace the inconsistent
use of error cleanups with a formal set of pool cleanups attached to
a subpool, which is destroyed on error. [Graham Leggett]
*) mod_cache: Change the signature of the store_body() provider function
within the mod_cache provider interface to support an "in" brigade
and an "out" brigade instead of just a single input brigade. This
gives a cache provider the option to consume only part of the brigade
passed to it, rather than the whole brigade as was required before.
This fixes an out of memory and a request timeout condition that would
occur when the original document was a large file. Update the
mod_disk_cache provider implementation to take into account the new API.
Introduce CacheReadSize and CacheReadTime directives to mod_disk_cache
to control the amount of data to attempt to cache before sending the
data on to the client in the "out" brigade. [Graham Leggett]
*) core: Add ErrorLogFormat to allow configuring error log format, including
additional information that is logged once per connection or request. Add
error log IDs for connections and request to allow correlating error log
lines and the corresponding access log entry. [Stefan Fritsch]
*) core: Disable sendfile by default. [Stefan Fritsch]
*) mod_cache: Check the request to determine whether we are allowed
to return cached content at all, and respect a "Cache-Control:
no-cache" header from a client. Previously, "no-cache" would
behave like "max-age=0". [Graham Leggett]
*) mod_cache: Use a proper filter context to hold filter data instead
of misusing the per-request configuration. Fixes a segfault on trunk
when the normal handler is used. [Graham Leggett]
*) mod_cgid: Log a warning if the ScriptSock path is truncated because
it is too long. PR 49388. [Stefan Fritsch]
*) vhosts: Do not allow _default_ in NameVirtualHost, or mixing *
and non-* ports on NameVirtualHost, or multiple NameVirtualHost
directives for the same address:port, or NameVirtualHost
directives with no matching VirtualHosts, or multiple ip-based
VirtualHost sections for the same address:port. These were
previously accepted with a warning, but the behavior was
undefined. [Dan Poirier]
*) mod_remoteip: Fix a segfault when using mod_remoteip in conjunction with
Allow/Deny. PR 49838. [Andrew Skalski <voltara gmail.com>]
*) core: DirectoryMatch can now match on the end of line character ($),
and sub-directories of matched directories are no longer implicitly
matched. PR49809 [Eric Covener]
Changes with Apache 2.3.8
*) suexec: Support large log files. PR 45856. [Stefan Fritsch]
*) core: Abort with sensible error message if no or more than one MPM is
loaded. [Stefan Fritsch]
*) mod_proxy: Rename erroronstatus to failonstatus.
[Daniel Ruggeri <DRuggeri primary.net>]
*) mod_dav_fs: Fix broken "creationdate" property.
Regression in version 2.3.7. [Rainer Jung]
Changes with Apache 2.3.7
*) SECURITY: CVE-2010-1452 (cve.mitre.org)
mod_dav, mod_cache, mod_session: Fix Handling of requests without a path
segment. PR: 49246 [Mark Drayton, Jeff Trawick]
*) mod_ldap: Properly check the result returned by apr_ldap_init. PR 46076.
[Stefan Fritsch]
*) mod_rewrite: Log errors if rewrite map files cannot be opened. PR 49639.
[Stefan Fritsch]
*) mod_proxy_http: Support the 'ping' property for backend HTTP/1.1 servers
via leveraging 100-Continue as the initial "request".
[Jim Jagielski]
*) core/mod_authz_core: Introduce new access_checker_ex hook that enables
mod_authz_core to bypass authentication if access should be allowed by
IP address/env var/... [Stefan Fritsch]
*) core: Introduce note_auth_failure hook to allow modules to add support
for additional auth types. This makes ap_note_auth_failure() work with
mod_auth_digest again. PR 48807. [Stefan Fritsch]
*) socache modules: return APR_NOTFOUND when a lookup is not found [Nick Kew]
*) mod_authn_cache: new module [Nick Kew]
*) configure: Add reallyall option for --enable-mods-shared. [Stefan Fritsch]
*) Fix Windows build when using VC6. [Gregg L. Smith <lists glewis com>]
*) mod_rewrite: Allow to set environment variables without explicitly
giving a value. [Rainer Jung]
*) mod_rewrite: Remove superfluous EOL from rewrite logging. [Rainer Jung]
*) mod_include: recognise "text/html; parameters" as text/html
PR 49616 [Andrey Chernov <ache nagual.pp.ru>]
*) CGI vars: allow PATH to be set by SetEnv, consistent with LD_LIBRARY_PATH
PR 43906 [Nick Kew]
*) Core: Extra robustness: don't try authz and segfault if authn
fails to set r->user. Log bug and return 500 instead.
PR 42995 [Nick Kew]
*) HTTP protocol filter: fix handling of longer chunk extensions
PR 49474 [<tee.bee gmx.de>]
*) Update SSL cipher suite and add example for SSLHonorCipherOrder.
[Lars Eilebrecht, Rainer Jung]
*) move AddOutputFilterByType from core to mod_filter. This should
fix nasty side-effects that happen when content_type is set
more than once in processing a request, and make it fully
compatible with dynamic and proxied contents. [Nick Kew]
*) mod_log_config: Implement logging for sub second timestamps and
request end time. [Rainer Jung]
Changes with Apache 2.3.6
*) SECURITY: CVE-2009-3555 (cve.mitre.org)
mod_ssl: Comprehensive fix of the TLS renegotiation prefix injection
attack when compiled against OpenSSL version 0.9.8m or later. Introduces
the 'SSLInsecureRenegotiation' directive to reopen this vulnerability
and offer unsafe legacy renegotiation with clients which do not yet
support the new secure renegotiation protocol, RFC 5746.
[Joe Orton, and with thanks to the OpenSSL Team]
*) SECURITY: CVE-2009-3555 (cve.mitre.org)
mod_ssl: A partial fix for the TLS renegotiation prefix injection attack
by rejecting any client-initiated renegotiations. Forcibly disable
keepalive for the connection if there is any buffered data readable. Any
configuration which requires renegotiation for per-directory/location
access control is still vulnerable, unless using OpenSSL >= 0.9.8l.
[Joe Orton, Ruediger Pluem, Hartmut Keil <Hartmut.Keil adnovum.ch>]
*) SECURITY: CVE-2010-0408 (cve.mitre.org)
mod_proxy_ajp: Respond with HTTP_BAD_REQUEST when the body is not sent
when request headers indicate a request body is incoming; not a case of
HTTP_INTERNAL_SERVER_ERROR. [Niku Toivola <niku.toivola sulake.com>]
*) SECURITY: CVE-2010-0425 (cve.mitre.org)
mod_isapi: Do not unload an isapi .dll module until the request
processing is completed, avoiding orphaned callback pointers.
[Brett Gervasoni <brettg senseofsecurity.com>, Jeff Trawick]
*) core: Filter init functions are now run strictly once per request
before handler invocation. The init functions are no longer run
for connection filters. PR 49328. [Joe Orton]
*) core: Adjust the output filter chain correctly in an internal
redirect from a subrequest, preserving filters from the main
request as necessary. PR 17629. [Joe Orton]
*) mod_cache: Explicitly allow cache implementations to cache a 206 Partial
Response if they so choose to do so. Previously an attempt to cache a 206
was arbitrarily allowed if the response contained an Expires or
Cache-Control header, and arbitrarily denied if both headers were missing.
