ChangeLog

All notable changes to the project are documented in this file.

v2.1.1 - 2024-01-05

Changes

  • Ignore IGMP proxy queries (source IP 0.0.0.0), they must never win a querier election.

Fixes

  • Fix #4: wrong type for getopt() return value
  • Fix #5: bug in igmpv2/igmpv3 option parser

v2.1.0 - 2021-09-12

Changes

  • Sync changes wrt preference/distance in pimdd.conf with pimd sources
  • Import cfparse.y from mrouted to replace homegrown .conf parser
    • Support for default-route-distance and default-route-metric
    • Support for assert-timeout
  • Import kernel interface probing from mrouted
    • Fixes issues with discovering IP addresses on Linux/FreeBSD
    • Allows for multinetting, using altnet directive from pimd
  • Align command line options with pimd
    • Rename options to match
    • Add -n and -s command line options
    • Add -l LEVEL to adjust log level
    • Add -i IDENT to assume another identity for .conf/.pid and syslog
    • Add -u FILE to override pimdd/pimctl IPC socket file
    • Add -p FILE to override pimdd PID file
    • Add -w SEC startup delay before interface probe
  • Rip out unfinished SNMP support
  • Add support for IGMPv3, querier and accepting membership reports
  • Add support for no phyint to start with all interfaces disabled
  • Add support for selecting phyint by name
  • Add support for pimctl, from pimd. The tool can be shared with pimd and used interchangeably between the two daemons
  • Add support for PIM Generation ID (genid) in PIM Hello
  • Add IP Router Alert option to IGMP and PIM messages, as per RFC2113
  • Inform PIM neighbors when we go down/reconfigure, PIM Hello holdtime=0
  • Trigger PIM Assert reelection when PIM neighbor goes down
  • Add support for querying RPF metric from Linux kernel
  • Drop periodic dump of vifs + mrt in log/stderr, we have pimctl now
  • Check for root privileges after checking command line args
  • Use configure'd paths for .conf, .pid, and .dump file
  • Update license files, stripping "contact Kurt .." and similar, also update pimd and mrouted license changes, thank you OpenBSD!
  • Cleanup, drop old pre-C89 __P() macro
  • Import safe string API functions from OpenBSD
  • Drop PIM-SM and DVMRP specific debug messages/levels, unused
  • Add systemd unit file, enabled automatically at configure time
  • Add man pages for pimd, pimctl, and pimd.conf in sections 8 and 5
  • Support for building .deb packages for Debian and Ubuntu based systemd

Fixes

  • Fix PIM Assert handling, with new assert-timeout .conf option
  • Fix k_del_vif(), does not work properly in Linux
  • Fix k_req_incoming() on FreeBSD
  • Fix 100% CPU usage, refactor linked list handling to use queue.h
  • Fix IGMP querier election bug, lost querier "flag" on interface when PIM DR election was lost. Thar draft spec PimDM is built around says largest IP wins DR election, but smallest wins IGMP, follow IGMP RFC
  • Only stop active/enabled VIFs, prevent bogus error messages
  • Fix unset DSCP value in PIM messages, Internet Control (DS6)
  • Fix RSRR (optional) build errors
  • Fix various memory leaks identified by Valgrind
  • Fix various scary bug identified by Coverity Scan

v0.2.1.0-beta1 - 2020-05-16

Changes

  • Converted to GNU Configure & Build system
  • Use netlink on Linux, SIOCGETRPF doesn't exist
  • Cleanup #ifdef hell in accept_igmp(), unreadable mess due to how various UNIX flavors handle SOCK_RAW and IP_HDRINCL
  • Use modern signal API, which all UNIX dialects support
  • Cleanup, rename reserved function name log() to logit()
  • Relocate source files to src/ subdirectory
  • Use strerror() instead of old sys_errlist[] & C:o
  • Import patches from FreeBSD ports collection:

Fixes

  • Always copy IFNAMSIZ bytes interface name to kernel
  • Fix missing break statement for SIGALARM in signal handler
  • Fix linux vs __linux__ ifdefs and drop a few SYSV ifdefs
  • Fix signed vs unsigned comparisons across the tree
  • Fix bit shift with negative value, fix imported from pimd, stems from FreeBSD PR https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202959

[v0.2.1.0-alpha21][] - 1998-12-30

Synch'ed with latest releave pimd (sparse) from USC:

  • XXX Timer changes in defs.h compatible with entry/prune timeout changes?

Changes

  • (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 Adaeda)
  • Now compiles under Linux (haven't check whether the PIMv2 kernel support in linux-2.1.103 works)
  • allpimrouters deleted from igmp.c (already defined in pim.c)
  • igmpmsg defined for IRIX
  • Linux patches to pim.c and defs.h, contributed by Jonathan Day [email protected]. Notes from Jonathan:

I'd like to report some bugs in the current version of PimD-Dense, which cause compilation to fail under Linux. In defs.h, external variables that have already been defined are being re-defined, causing the compilation to fail. In pim.c, there is a typing error - if->ip_len is referred to, as opposed to ip->ip_len. I've included the changes I've been using to fix these bugs.

Fixes

  • Fixed entry timer initialization in route.c:process_cache_miss()
  • BUG FIX: fix TIMEOUT definitions in difs.h (bug report by Nidhi Bhaskar) (originally, if timer value less than 5 seconds, it won't become 0)
  • Fixed delay time for LAN prune scheduling to 4 seconds to comply with spec, which says that prunes should be delayed for time strictly greater than the maximum join delay of 3 seconds.
  • Fixed Prune timeout behavior:
    • Prune timeout now triggers graft
    • If prune and entry timeout simultaneously, the prune is timed out first, triggering an entry timer refresh.
  • Fixed Assert sending so that asserts sent from upstream routers without routes to the source send pref and metric of 0x7fffffff.

June 19, 1998

Modifications to comply with the latest PIM-DM spec revision:

  • Graft retransmission period is now 3 seconds
  • Random Join/Prune delay is 3 seconds

Some still unresolved issues:

  • Upstream Address field in Graft and Graft-Ack

v0.2.1.0-alpha15 - May 29, 1998

Synched in fixes from Pavlin's pimd-2.1.0-alpha15:

  • Bug fixes related to NetBSD, thanks to Heiko W.Rupp [email protected]
  • MRT_PIM completely replaced by MRT_ASSERT

v0.2.1.0-alpha11 - May 29, 1998

This is the first release of the the PIM Dense-Mode version of pimd.

For now, I have simply prepended "0." onto the version number for Pavlin Ivanov Radoslavov's Sparse-Mode pimd, from which this code was derived. A new 1.0.x-alpha version number will be assigned upon the initial public release of this code.
