pimd | Change Log

Version 2.3.1: November 15, 2015

Bug fix release.

Changes

Bug Fixes

  • Issue #53: Build problem with Clang on FreeBSD
  • Issue #55: Default config uses /etcpimd.conf instead of /etc/pimd.conf. Slashes added and now pimd -h lists the default path instead of a hard coded string.
  • Issue #60: Fix minor spelling errors.

Version 2.3.0: July 31, 2015 – PIM-SSM & IGMPv3 release!

The significant new features in this release would not have been possible if not for the hard work of Markus Veranen mailto:markus.veranen@gmail.com

Tested on Ubuntu 14.04 (GLIBC/Linux 3.13), Debian 8.1 (GLIBC/Linux 3.16), FreeBSD, NetBSD, and OpenBSD.

Changes and New Features

  • Support for PIM-SSM and IGMPv3, by Markus Veranen
  • IGMPv3 is now default, use phyint ifname igmpv2 for old behaviour
  • Default IGMP query interval has changed from 125 sec to 12 sec

    In pimd.conf: igmp-query-interval <SEC>

  • Default IGMP querier timeout has changed from 255 sec to 42 sec

    In pimd.conf: igmp-querier-timeout <SEC>

  • The built-in IGMP robustness value changed from 2 to 3
  • Support for changing the PIM Hello interval, by Markus Veranen

    In pimd.conf: hello-interval <SEC>

  • Support for multiple multicast routing tables, and running multiple pimd instances, by Markus Veranen. (Only supported on Linux atm.)
  • Support for advertising, and acting upon changes to, Generation ID in PIM Hello messages, by Markus Veranen
  • Support for advertising DR Priority option in PIM Hello messages. If all routers on a LAN send this option this value is used in the DR election rather than the IP address. The priority is configured per phyint. This closes the long-standing issue #5.
  • Distribution archive format changed from XZ to Gzip, for the benefit of OpenBSD that only ships Gzip in the base system.

New pimd.conf syntax!

The pimd.conf syntax has been changed in this release. Mainly, the configuration file now use dashes - instead of underscore _ as word separators. However several settings have also been renamed to be more familiar to commands used by major router vendors:

bsr-candidate
replaces cand_bootstrap_router
rp-candidate
replaces cand_rp
group-prefix
replaces group_prefix
rp-address
replaces rp_address
spt-threshold
replaces the two deprecated switch_register_threshold and switch_data_threshold settings
hello-interval
replaces hello_period
default-route-distance
replaces default_source_preference
default-route-metric
replaces default-source-metric

Also, for phyint the preference sub-option has been replaced with the less confusing distance and ttl-threshold replaces threshold. See the README or the man page for more information on the metric preference and admin distance confusion.

*Note:* The =pimd.conf= parser remains backwards compatible with the old syntax!

Compile Time Features

The following are new features that must be enabled at compile time, using the configure script, to take effect. For details, see ./configure --help

--prefix=PATH
Standard prefix to be used at installation, default /usr/local
--sysconfdir=PATH
Prefix path to be used for pimd.conf, default /etc, unless --prefix is given.
--embedded-libc
Enable uClib or musl libc build, on Linux.
--disable-exit-on-error
Allow pimd to continue running despite encountering errors.
--disable-pim-genid
Disable advertisement of PIM Hello GenID, use for compatibility problems with older versions of pimd.
--with-max-vifs=MAXVIFS
Raise max number of VIFs to MAXVIFS.

Note: this requires raising MAXVIFS in the kernel as well! Most kernels cannot handle >255, if this is a problem, try using multiple multicast routing tables instead.

--disable-masklen-check
Allow tunctl VIFs with masklen 32.

Bug Fixes

  • Fix issue #40: FTBS with ./configure --enable-scoped-acls
  • Properly support cross compiling. It is now possible to actually define the $CROSS environment variable when calling make to allow cross compiling pimd. Should work with both GCC and Clang. Tested on Ubuntu, Debian and FreeBSD.

Version 2.2.1: April 20, 2015

Bug Fixes

  • Fix another problem with issue #22 (reopened), as laid out in issue #37. This time the crash is induced when there is a link down event. Lot of help debugging the propblem by @mfspeer, who also suggested the fix – to call pim_proto.c:delete_pim_nbr() in vif.c:stop_vif() instead of just calling free.
  • Fix issue with not checking return value of open() in daemonizing code in main(), found by Coverity Scan.
  • Fix issue with scoped phyint in config.c, found by Coverity Scan. The masklen may not be zero, config file problem, alert the user.

Version 2.2.0: December 28, 2014

Changes & New Features

  • Support for IP fragmentation of PIM register messages, by Michael Fine, Cumulus Networks
  • Support /LEN syntax in phyint to complement masklen LEN, issue #12
  • Add support for /31 networks, point-to-point, thanks to Apollon Oikonomopoulos
  • Remove old broken SNMP support
  • OpenBSD inspired cleanup (deregister)
  • General code cleanup, shorten local variable names, func decl. etc.
  • Support for router alert IP option in IGMP queries
  • Support for reading IGMPv3 membership reports
  • Update IGMP code to support FreeBSD >= 8.x
  • Retry read of routing tables on FreeBSD
  • Fix join/leve of ALL PIM Routers for FreeBSD and other UNIX kernels
  • Tested on FreeBSD, NetBSD and OpenBSD
  • Add very simple homegrown configure script
  • Update and document support for rp_address, cand_rp, and cand_bootstrap_router
  • Add new spt_threshold to replace existing switch_register_threshold and switch_data_threshold settings. Cisco-like and easier to understand

Bug Fixes

  • Fix to avoid infinite loop during unicast send failure, by Alex Tessmer
  • Fix bug in bootstrap when configured as candidate RP, issue #15
  • Fix segfault in accept_igmp(), issue #29
  • Fix default source preference, should be 101 (not 1024!)
  • Fix ip_len handling on older BSD’s, thanks to Olivier Cochard-Labbé, issue #23
  • Fix default prefix len in static RP example in pimd.conf, should be /4
  • Fix issue #31: Make IGMP query interval and querier timeout configurable
  • Fix issue #33: pimd does not work in background under FreeBSD
  • Fix issue #35: support for timing out other queriers from mrouted
  • Hopefully fix issue #22: Crash in (S,G) state when neighbor is lost
  • Misc. bug fixes thanks to Coverity Scan, static code analysis tool https://scan.coverity.com/projects/3319

Version 2.1.8: October 22, 2011

Changes & New Features

Bug Fixes

  • A serious bug in pim_proto.c:receive_pim_register() was found and fixed by Jean-Pascal Billaud. In essence, the RP check was broken since the code only looked at my_cand_rp_address, which is not set when using the rp_address config. Everything works fine with auto-RP mode though. This issue completely breaks the register path since the JOIN(S,G) is never sent back …
  • Fix FTBFS issues reported from Debian. Later GCC versions trigger unused variable warnings. Patches and cleanup Antonin Kral mailto:a.kral@bobek.cz

Version 2.1.7: January 9, 2011

Changes & New Features

Version 2.1.6: January 8, 2011

Changes & New Features

  • Debian package now conflicts with smcroute, in addition to mrouted. It is only possible to run one multicast routing daemon at a time, kernel limitation.
  • The location of the dump file(s) have been moved from /var/tmp to /var/lib/misc due to the insecure nature of /var/tmp. See more below.

Bug Fixes

  • kern.c:k_del_vif(): Fix build error on GNU/kFreeBSD
  • CVE-2011-0007: Insecure file creation in /var/tmp. “On USR1, pimd will write to /var/tmp/pimd.dump a dump of the multicast route table. Since /var/tmp is writable by any user, a user can create a symlink to any file he wants to destroy with the content of the multicast routing table.”

Version 2.1.5: November 21, 2010

Changes & New Features

  • Improved error messages in kern.c
  • Renamed CHANGES to ChangeLog

Bug Fixes

  • Import mrouted fix: on GNU/Linux systems (only!) the call to kern.c:k_del_vif() fails with: setsockopt MRT_DEL_VIF on vif 3: Invalid argument. This is due to differences in the Linux and *BSD MRT_DEL_VIF API. The Linux kernel expects to receive a struct vifctl associated with the VIF to be deleted, *BSD systems on the other hand expect to receive the index of that VIF.

    Bug reported and fixed on mrouted by Dan Kruchinin mailto:dkruchinin@acm.org

Version 2.1.4: September 25, 2010

Changes & New Features

  • Updates for support on Debian GNU/kFreeBSD, FreeBSD kernel with GNU userland.

Bug Fixes

  • Lior Dotan mailto:liodot@gmail.com reports that pimd 2.1.2 and 2.1.3 are severely broken w.r.t. uninformed systematic replace of bcopy() with memcpy() API.

Version 2.1.3: September 8, 2010

Changes & New Features

  • debug.c:syslog(): Removed GNU:ism %m, use strerror(errno) instead.
  • Cleanup and ansification of a couple of files: rp.c, mrt.c, vif.c, route.c
  • Initialize stack variables to silence overzealous GCC on PowerPC and S/390. Debian bug 595584, this closes pimd issue #3 on GitHub.

Bug Fixes

  • Merge bug fix for static-rp configurations from Kame’s pim6sd route.c r1.28
  • Close TODO item by merging in relevant changes from Kame’s pim6sd vif.c r1.3
  • Tried fixing debug.c:logit() build failure on Sparc due to mixup in headers for tv_usec type.

Version 2.1.2: September 4, 2010

Changes & New Features

  • License change on mrouted code from OpenBSD team => pimd fully free under the simlified 3-clause BSD license! This was also covered in v2.1.0-alpha29.17, but now all files have been updated, including LICENSE.mrouted.
  • Code cleanup and ansification.
  • Simplified Makefile so that it works seamlessly on GNU Make and BSD PMake.
  • Replaced all calls to bzero() and bcopy() with memset() and memcpy().
  • Use getopt_long() for argument parsing.
  • Add, and improve, -h,–help output.
  • Add -f,–foreground option.
  • Add -v,–version option.
  • Add -l,–reload-config which sends SIGHUP to a running daemon.
  • Add -r,–show-routes which sends SIGUSR1 to a running daemon.
  • Add -q,–quit-daemon which sends SIGTERM to a running daemon.
  • Make it possible to call pimd as a regular user, for –help and –version.
  • Man page cleaned up, a lot, and updated with new options.

Bug Fixes

  • Replaced dangerous old string functions with safer snprintf() and strlcpy()
  • Added checks for malloc() return values, all over the code base.
  • Fixed issues reported by Sparse (CC=cgcc).
  • Make sure to retry syscalls recvfrom() and sendto() on signal (SIGINT).

Changes & New Features

  • Integrated the latest Debian patches from pimd_2.1.0-alpha29.17-9.diff.gz
  • Fixed the new file include/linux/netinet/in-my.h (Debian) so that the #else fallback uses the system netinet/in.h, which seems to work now.
  • Bumped version number, this code has been available for a while now.

Version 2.1.0-alpha29.19: January 14, 2005

Bug Fixes

  • Don’t ignore PIM Null Register messages if the IP version of the inner header is not valid.
  • Add a missing bracket inside rsrr.c (a bug report and a fix by mailto:seyon@oullim.co.kr)

Version 2.1.0-alpha29.18: May 21, 2003

Version 2.1.0-alpha29.17: March 20, 2003

Changes & New Features

  • The mrouted license, LICENSE.mrouted, updated with BSD-like license!! Thanks to the OpenBSD folks for the 2 years of hard work to make this happen:

    http://www.openbsd.org/cgi-bin/cvsweb/src/usr.sbin/mrouted/LICENSE

  • Moved the pimd contact email address upfront in README. Let me repeat that here: If you have any questions, suggestions, bug reports, etc., do NOT send them to the PIM IETF Working Group mailing list! Instead, use the contact email address specified in README.

Version 2.1.0-alpha29.16: February 18, 2003

Bug Fixes

Version 2.1.0-alpha29.15: February 12, 2003

Bug Fixes

[problem]
PIM join does not go upstream in the following topology, because oif-list
is NULL after subtracting iif from oif-list.

    receiver---rtr1---|
               rtr2---|---rtr3----sender

            rtr1's nexthop to sender = rtr2
            rtr2's nexthop to sender = rtr3

[reason]
Owing to a difference between RFC2362 and the new pim-sm draft.
[solution]
Prunes iif from oiflist when installing it into kernel, instead of
PIM route calculation time.

Version 2.1.0-alpha29.14: February 10, 2003

Bug Fixes

  • Bugfix in calculating the netmask for POINTOPOINT interface in config.c. Bug report by J.W. (Bill) Atwood mailto:bill@cs.concordia.ca

Bug Fixes

Bug reports and fixes by SAKAI Hiroaki mailto:sakai.hiroaki@finet.fujitsu.com

  • init_routesock(): Bugfix: initializing a forgotten variable. The particular code related to that variable is commented-out by default, but a bug is a bug.
  • main.c:restart(): Bugfix: close the udp_socket only when it is is different from igmp_socket.
  • main.c:main(): if SIGHUP signal is received, reconstruct readers and nfds
  • Three serious bug fixes thanks to Jiahao Wang mailto:jiahaow@yahoo.com.cn and Bo Cheng mailto:bobobocheng@hotmail.com:
    • pim_proto.c:receive_pim_join_prune(): two bugfixes related to the processing of (*,*,RP)
    • pim_proto.c:add_jp_entry(): Bugfix regarding adding prune entries
  • Remove the FTP URL from the various README files, and replace it with an HTTP URL, because the FTP server on catarina.usc.edu is not operational anymore.

Version 2.1.0-alpha29.10: April 26, 2002

Bug Fixes

  • Widen the space for “Subnet” addresses printed under “Virtual Interface Table”
  • Added (commented-out code) to enable different interfaces to belong to overlapping subnets. See around line 200 in config.c
  • Bugfix in handling of Join/Prune messages when there is one join and one prune for the same group. Thanks to Xiaofeng Liu mailto:liu_xiao_feng@yahoo.com.

Version 2.1.0-alpha29.9: November 13, 2001

Changes & New Features

First three entries contributed by Hiroyuki Komatsu mailto:komatsu@taiyaki.org

  • Print line number if there is conf file error.
  • If there is an error in the conf file, pimd won’t start.
  • GRE configuration examples added to README.config.
  • New file README.debug (still very short though).

Bug Fixes

Version 2.1.0-alpha29.8: September 16, 2001

Changes & New Features

Version 2.1.0-alpha29.7: September 10, 2001

Changes & New Features

  • Added “phyint altnet” (see pimd.conf for usage) for allowing some senders look like directly connected to a local subnet. Implemented by Marian Stagarescu mailto:marian@bile.cidera.com
  • Added “phyint scoped” (see pimd.conf for usage) for administartively disabling the forwarding of multicast groups. Implemented by Marian Stagarescu mailto:marian@bile.cidera.com
  • The License has changed from the original USC to the more familiar BSD-like (the KAME+OpenBSD guys brought to my attention that the original working in the USC license “…and without fee…” is ambiguous and makes it sound that noone can distribute pimd as part of some other software distribution and charge for that distribution.
  • RSRR disabled by default in Makefile

Bug Fixes

Version 2.1.0-alpha29.6: May 4, 2001

Bug Fixes

Version 2.1.0-alpha29.5: February 22, 2001

Changes & New Features

  • VIFM_FORWARDER() macro renamed to VIFM_LASTHOP_ROUTER.
  • Mini-FAQ entries added to README.

Bug Fixes

  • When there is a new member, add_leaf() is called by IGMP code for any router, not only for a DR. The reason is because not only the DR must know about local members, but the last-hop router as well (so eventually it will initiate a SPT switch). Similar fixes to add_leaf() inside route.c as well. Problem reported by Hitoshi Asaeda mailto:asaeda@yamato.ibm.com. XXX: Note the lenghty comment in the beginning of add_leaf() about a pimd desing problem that may result in SPT switch not initiated immediately by the last-hop router.
  • DR entry timer bug fix in timer.c: When (*,G)’s iif and (S,G)’s iif are not same, (S,G)’s timer for the DR doesn’t increase. Reported indirectly by mailto:toshiaki.nakatsu@fujixerox.co.jp

Version 2.1.0-alpha29.4: December 1, 2000

Changes & New Features

  • README cleanup + Mini-FAQ added
  • igmp_proto.c: printf argument cleanup (courtesy KAME)
  • main.c:restart(): forgotten printf argument added (courtesy KAME)

Bug Fixes

  • kern.c:k_stop_pim(): Fix the ordering of MRT_PIM and MRT_DONE, thanks to Hitoshi Asaeda mailto:asaeda@yamato.ibm.co.jp.
  • route.c:add_leaf(): mrtentry creation logic bug fix. If the router is not a DR, a mrtentry is never created. Tanks to Hitoshi Asaeda mailto:asaeda@yamato.ibm.co.jp & (indirectly) mailto:toshiaki.nakatsu@fujixerox.co.jp
  • pim_proto.c: Two critical bug fixes. J/P prune suppression related message and J/P message with (*,*,RP) entry inside. Thanks to Azzurra Pantella mailto:s198804@studenti.ing.unipi.it and Nicola Dicosmo from University of Pisa
  • pim_proto.c:receive_pim_bootstrap(): BSR-related fix from Kame’s pim6sd. Even when the BSR changes, just schedule an immediate advertisemnet of C-RP-ADV, instead of sending message, in order to avoid sending the advertisement to the old BSR. In response to comment from mailto:toshiaki.nakatsu@fujixerox.co.jp

Version 2.1.0-alpha29.3: October 13, 2000

Bug Fixes

  • ADVANCE() bug fix in routesock.c (if your system doesn’t have SA_LEN) thanks to Eric S. Johnson mailto:esj@cs.fiu.edu

Version 2.1.0-alpha29.2: October 13, 2000

NB: THIS pimd VERSION WON’T WORK WITH OLDER PIM-SM KERNEL PATCHES (kernel patches released prior to this version)!

Changes & New Features

  • The daemon that the kernel will prepare completely the inner multicast packet for PIM register messages that the kernel is supposed to encapsulate and send to the RP.
  • Now pimd compiles on OpenBSD-2.7. PIM control messages exchange test passed. Ddon’t have the infrastructure to perform more complete testing.
  • main.c:cleanup(): Send PIM_HELLO with holdtime of ‘0’ if pimd is going away, thanks to JINMEI Tatuya mailto:jinmei@isl.rdc.toshiba.co.jp
  • include/netinet/pim.h updated
  • pimd code adapted to the new struct pim definition.
  • Added PIM_OLD_KERNEL and BROKEN_CISCO_CHECKSUM entries in the Makefile.
  • Don’t ignore kernel signals if any of src or dst are NULL.
  • Don’t touch ip_id on a PIM register message
  • README cleanup: kernel patches location, obsoleted systems clarification, etc.
  • k_stop_pim() added to cleanup() in main.c (courtesy Kame)

Bug Fixes

  • RANDOM()-related bug fix re. jp_value calculation in pim_proto.c, thanks to JINMEI Tatuya mailto:jinmei@isl.rdc.toshiba.co.jp
  • realloc() related memory leak bug in config_vifs_from_kernel() in config.c courtesy Kame’s pim6sd code.
  • Solaris-8 fixes thanks to Eric S. Johnson mailto:esj@cs.fiu.edu
  • BROKEN_CISCO_CHECKSUM bug fix thanks to Eric S. Johnson mailto:esj@cs.fiu.edu and Hitoshi Asaeda.
  • main.c: 1000000 usec -> 1 sec 0 usec. Fix courtesy of the Kame project
  • main.c:restart() fixup courtesy of the Kame project
  • various min. message length check for the received control messages courtesy of the Kame project. XXX: the pimd check is not enough!
  • VIF name string comparison fix in routesock.c:getmsg() courtesy of the Kame project
  • missing brackets added inside age_routes() (a bug that will show up only if KERNEL_MFC_WC_G was defined); courtesy of the Kame project

Version 2.1.0-alpha28: March 15, 2000

Changes & New Features

  • added #ifdef BROKEN_CISCO_CHECKSUM (disabled by default) to make cisco RPs happy (read the comments in pim.c)
  • added #ifdef PIM_TYPEVERS_DECL in netinet/pim.h as a workaround that ANSI-C doesn’t guarantee that bit-fields are tightly packed together (although all modern C compilers should not create a problem).

Bug Fixes

Version 2.1.0-alpha27: January 21, 2000

NB: this release may the the last one from 2.1.0. The next release will be 2.2.0 and there will be lots of changes inside.

Bug Fixes

  • Bug fix in rp.c:add_grp_mask() and rp.c:delete_grp_mask(): in some cases if the RPs are configured with nested multicast prefixes, the add/delete may fail. Thanks to Hitoshi Asaeda and the KAME team for pointing out this one.

Version 2.1.0-alpha26: October 28, 1999

Bug Fixes

  • Bug fix in receive_pim_register() in pim_proto.c:ntohl() was missing inside IN_MULTICAST(). Thanks to Fred Griffoul mailto:griffoul@ccrle.nec.de
  • Bug report and fix by Hitoshi Asaeda mailto:asaeda@yamato.ibm.co.jp in pim_proto.c:receive_pim_cand_rp_adv() (if a router is not a BSR). Another bug in rp.c:delete_grp_mask_entry(): an entry not in the head of the list was not deleted propertly.
  • Some VIFF_TUNNEL checks added or deleted in various places. Slowly preparing pimd to be able to work with GRE tunnels…

Version 2.1.0-alpha25: August 30, 1999

Bug reports and fixes by Hitoshi Asaeda mailto:asaeda@yamato.ibm.co.jp inside parse_reg_threshold() and parse_data_threshold() in config.c

Changes & New Features

  • Successfully added multicast prefixes configured in pimd.conf are displayed at startup
  • Use include/freebsd as FreeBSD-3.x include files and include/freebsd2 for FreeBSD-2.x.

Bug Fixes

  • Test is performed whether a PIM_REGISTER has invalid source and/or group address of the internal packet.

Version 2.1.0-alpha24: August 9, 1999

Changes & New Features

  • PIM_DEFAULT_CAND_RP_ADV_PERIOD definition set to 60, but default ‘time’ value for inter Cand-RP messages is set in pimd.conf to 30 sec.
  • PIM_REGISTER checksum verification in receive_pim_register() relaxed for compatibility with some older routers. The checksum has to be computed only over the first 8 bytes of the PIM Register (i.e. only over the header), but some older routers might compute it over the whole packet. Hence, the checksum verification is over the first 8 bytes first, and if if it fails, then over the whole packet. Thus, pimd that is RP should still work with older routers that act as DR, but if an older router is the RP, then pimd cannot be the DR. Sorry, don’t know which particular routers and models create the checksum over the whole PIM Register (if there are still any left).

Version 2.1.0-alpha23: May 24, 1999

Changes & New Features

  • Finally pimd works under Linux (probably 2.1.126, 2.2.x and 2.3.x). However, a small fix in the kernel linux/net/ipv4/ipmr.c is necessary. In function pim_rcv(), remove the call to ip_compute_csum():

  • Bug fixes to compile under newer Linux kernel (linux-2.1.127) To compile for older kernels ( ver < ???), add -Dold_Linux to the Makefile
  • For convenience, the include/linux/netinet/{in.h,mroute.h} files are added, with few modifications applied.

Version 2.1.0-alpha21: November 4, 1998

Bug Fixes

  • pim_proto.c:join_or_prune(): Bug fixes in case of (S,G) overlapping with (*,G). Bug report by Dirk Ooms mailto:Dirk.Ooms@alcatel.be
  • route.c:change_interfaces(): Join/Prune (*,G), (*,*,RP) fire timer optimization/fix.

Version 2.1.0-alpha20: August 26, 1998

Changes & New Features

  • (Almost) all timers manipulation now use macros
  • pim.h and pim_var.h are in separate common directory
  • Added BSDI definition to pim_var.h, thanks to Hitoshi Asaeda.

Bug Fixes

  • fix TIMEOUT definitions in difs.h (bug report by Nidhi Bhaskar) (originally, if timer value less than 5 seconds, it won’t become 0) It is HIGHLY recommended to apply that fix, so here it is:
-------------BEGIN BUG FIX-------------------
  1) Add the following lines to defs.h (after #define FALSE):

#ifndef MAX
#define MAX(a,b) (((a) >= (b))? (a) : (b))
#define MIN(a,b) (((a) <= (b))? (a) : (b))
#endif /* MAX & MIN */

  2) Change the listed below TIMEOUT macros to:

#define IF_TIMEOUT(timer)		\
	if (!((timer) -= (MIN(timer, TIMER_INTERVAL))))

#define IF_NOT_TIMEOUT(timer)		\
	if ((timer) -= (MIN(timer, TIMER_INTERVAL)))

#define TIMEOUT(timer)			\
	(!((timer) -= (MIN(timer, TIMER_INTERVAL))))

#define NOT_TIMEOUT(timer)		\
	((timer) -= (MIN(timer, TIMER_INTERVAL)))
---------------END BUG FIX-------

Version 2.1.0-alpha19: July 29, 1998

Both bug reports by Chirayu Shah mailto:shahzad@torrentnet.com-

Bug Fixes

  • bug fix in find_route() when searching for (*,*,RP)
  • bug fix in move_kernel_cache(): no need to do move_kernel_cache() from (*,*,R) to (*,G) first when we call move_kernel_cache() for (S,G)

Version 2.1.0-alpha18: May 29, 1998

Changes & New Features

  • Now compiles under Linux (haven’t checked whether the PIMv2 kernel support in linux-2.1.103 works)

Bug Fixes

  • parse_default_source*() bug fix (bug reports by Nidhi Bhaskar)
  • allpimrouters deleted from igmp.c (already defined in pim.c)
  • igmpmsg defined for IRIX

Version 2.1.0-alpha17: May 21, 1998

Changes & New Features

  • (*,G) MFC kernel support completed and verified. Compile with KERNEL_MFC_WC_G defined in Makefile, but then must use it only with a kernel that supports (*,G), e.g. pimkern-PATCH_7. Currently, kernel patches available for FreeBSD and SunOS only.

Bug Fixes

  • MRTF_MFC_CLONE_SG flag set after delete_single_kernel_cache() is called

Version 2.1.0-alpha16: May 19, 1998

Changes & New Features

  • PIM registers kernel encapsulation support. Build with PIM_REG_KERNEL_ENCAP defined in Makefile.
  • (*,G) MFC support. Build with KERNEL_MFC_WC_G defined in Makefile. However, MFC_WC_G is still not supported with pimkern-PATCH_6, must disable it for now.
  • mrt.c:delete_single_kernel_cache_addr(): New function, uses source, group to specify an MFC to be deleted

Version 2.1.0-alpha15: May 14, 1998

Version 2.1.0-alpha14: May 12, 1998

Version 2.1.0-alpha13: May 11, 1998

Changes & New Features

  • If the RP changes, the necessary actions are taken to pass the new RP address to the kernel. To be used for kernel register encap. support. Wnat needs to be done is: (a) add rp_addr entry to the mfcctl structure, and then just set it in kern.c:k_chf_mfc(). Obviously, the kernel needs to support the register encapsulation (instead of sending WHOLEPKT to the user level). In the near few days will make the necessary kernel changes.
  • change_interfaces(): Added “flags” argument. The only valid flag is MFC_UPDATE_FORCE, used for forcing kernel call when only the RP changes.
  • k_chg_mfc() has a new argument: rp_addr. To be used for kernel register encapsulation support
  • MRT_PIM completely replaced by MRT_ASSERT
  • move_kernel_cache(): Argument MFC_MOVE_FORCE is a flag instead of TRUE/FALSE
  • process_cache_miss(): removed unneeded piece of code

Version 2.1.0-alpha12: May 10, 1998

Changes & New Features

  • Use the cleaned up netinet/pim.h
  • Remove the no needed anymore pim header definition in pimd.h
  • Don’t use MRT_PIM in in kern.c anymore, replaced back with MRT_ASSERT.
  • added default_source_metric and default_source_preference (1024) because the kernel’s unicast routing table is not a good source of info; configurable in pimd.conf
  • Can now compile under NetBSD-1.3, thanks to Heiko W.Rupp mailto:hwr@pilhuhn.de

Bug Fixes

  • Incorrect setup of the borderBit and nullRegisterBit (different for big and little endian machines) fixed; *_BORDER_BIT and *NULL_REGISTER_BIT redefined
  • don’t send pim_assert on tunnels or register vifs (if for whatever reason we receive on such interface)
  • ignore WRONGVIF messages for register and tunnel vifs (the cleaned up kernel mods dont send such signal, but the older (before May 9 ‘98) pimd mods that signaling was enabled

Version 2.1.0-alpha11: March 16, 1998

Changes & New Features

  • vif.c:find_vif_direct_local(): New function, used in routesock.c, igmp_proto.c
  • Use MFC_MOVE_FORCE/MFC_MOVE_DONT_FORCE flag in mrt.c, route.c, pim_proto.c, when need to move the kernel cache entries between (*,*,RP), (*,G), (S,G)
  • new timer related macros: SET_TIMER(), FIRE_TIMER(), IF_TIMER_SET(), IF_TIMER_NOT_SET()

Bug Fixes

  • timer.c:age_routes(): bunch of fixes regarding J/P message fragmentation
  • route.c:process_wrong_iif(): (S,G) SPT switch bug fix: ANDed MRTF_RP fixed to MRTF_RP
  • pim_proto.c & timer.c: (S,G) Prune now is sent toward RP, when iif toward S and iif toward RP are different
  • pim_proto.c:join_or_prune() bug fixes
  • pim_proto.c: (S,G)Prune entry’s timer now set to J/P message holdtime
  • pim_proto.c:receive_pim_join_prune(): Ensure pruned interfaces are correctly reestablished
  • timer.c:age_routes(): now (S,G) entry with local members (inherited from (*,G)) is timeout propertly
  • timer.c:age_routes(): (S,G) J/P timer restarted propertly
  • timer.c:age_routes(): check also the (S,G)RPbit entries in the forwarders and RP and eventually switch to the shortest path if data rate too high
  • route.c:process_wrong_vif() fire J/P timer
  • route.c:switch_shortest_path(): reset the iif toward S if there is already (S,G)RPbit entry

Version 2.1.0-alpha10: March 3, 1998

Temp. non-public release.

Changes & New Features

  • `interval` can be applied for data rate check. The statement in pimd.conf that only the default value will be used is not true anymore.
  • The RP-initiated and the forwarder-initiated (S,G) switch threshold rate can be different.
  • pim_proto.c:receive_pim_register(): check if I am the RP for that group, and if “no”, send PIM_REGISTER_STOP (XXX: not in the spec, but should be!)
  • pim_proto.c:receive_pim_register_stop(): check if the PIM_REGISTER_STOP originator is really the RP, before suppressing the sending of the PIM registers. (XXX: not in the spec but should be there)
  • rp.c:check_mrtentry_rp(): new function added to check whether the RP address is the corresponding one for the given mrtentry
  • debug.c:dump_mrt() timer values added
  • route.c: add_leaf(), process_cache_miss(), process_wrong_iif() no routing entries created for the LAN scoped addresses
  • DEBUG_DVMRP_DETAIL and DEBUG_PIM_DETAIL added

Bug Fixes

  • mrt.c:add_kernel_cache(): no kernel cache duplicates
  • mrt.c:move_kernel_cache(): if the iif of the (*,*,R) (or (*,G)) and (S,G) are different, dont move the cache entry “UP”
  • timer.c:age_routes(): (S,G) add_jp_entry() flag fixed, SPT switch related.
  • kern.c:k_get_sg_cnt(): modified to compensate for the kernel’s return code bug for getting (S,G) byte count (SIOCGETSGCNT)
  • pim_proto.c:receive_pim_register(): if the (S,G) oif is NULL, now checks whether the iif is register_vif

Version 2.1.0-alpha9: February 18, 1997

Changes & New Features

  • “non-commersial” statement deleted from the copyright message
  • mrinfo support added
  • mtrace support added (not completed and not enough tested)
  • if invalid local address for cand_rp or cand_bootstrap_router in pimd.conf, automatically will use the largest local multicast enabled address
  • “include” directory for FreeBSD and SunOS added, so now pimd can be compiled without having the necesary “include” files added to your system. Probably a bad idea and may remove it later.
  • some default values for the IP headers of the IGMP and PIM packets are fixed
  • VIFF_PIM_NBR and VIFF_DVMRP_NBR flags added
  • VIFF_REGISTER now included in the RSRR vifs report
