! 8: * Version 2.3.2: March 10, 2016
! 9:
! 10: Bug fix release. All users should upgrade, in particular FreeBSD users!
! 11:
! 12: ** Changes
! 13: - Minor code cleanup and readability changes to simplify the code.
! 14: - Update to libite v1.4.2 with improved =min()=/=max()= macros
! 15: - Use =-Wextra= not =-Werror= in default =CFLAGS=, this to ensure that pimd
! 16: still builds OK on newer and more pedantic compilers
! 17: - Update man page and example `pimd.conf` with details on `rp-candidate`
! 18: `bsr-candidate`, two very important settings for correct operation.
! 19:
! 20: ** Bug Fixes
! 21: - Issue #57: Multicast routing table not updated on FreeBSD. Introduced
! 22: with issue #23, in pimd v2.2.0. Too intrusive changes altered handling
! 23: (forwarding) of PIM register messages. This only affects BSD systems,
! 24: in particular FreeBSD 10.2 (current), or any FreeBSD < 11.0
! 25: - Issue #63: Mika Joutsenvirta <mailto:mika.joutsenvirta@insta.fi> found
! 26: and fixed serious issues with the PIM Assert timeout handling.
! 27: - Issue #65: Missing slash in config file path when using env. variable
! 28: - Issue #66: Make it possible to run =pimd= without a configuration
! 29: file. If =pimd= cannot find its configuration file it will use
! 30: built-in fallback settings for =bsr-candidate= and =rp-candidate=.
! 31: This to ensure you do not end up with a non-working setup. To disable
! 32: =bsr-candidate= and =rp-candidate=, simply leave them out of your
! 33: config file, and make sure =pimd= can find the file.
! 34: - Issue #69: Rate limit only what is actually logged. The =logit()=
! 35: function counted filtered messages, causing long periods of silence
! 36: for no reason. Fix by Apollon Oikonomopoulos <mailto:apollon@skroutz.gr>
! 37:
! 38: #+LATEX: \newpage
! 39: * Version 2.3.1: November 15, 2015
! 40:
! 41: Bug fix release.
! 42:
! 43: ** Changes
! 44: - Let build system handle missing libite GIT submodule
! 45: - Issue #61: Debian packaging moved to https://github.com/bobek/pkg-pimd
! 46:
! 47: ** Bug Fixes
! 48: - Issue #53: Build problem with Clang on FreeBSD
! 49: - Issue #55: Default config uses =/etcpimd.conf= instead of
! 50: =/etc/pimd.conf=. Slashes added and now =pimd -h= lists
! 51: the default path instead of a hard coded string.
! 52: - Issue #60: Fix minor spelling errors.

! 55: * Version 2.3.0: July 31, 2015 -- /PIM-SSM & IGMPv3 release!/
! 56:
! 57: The significant new features in this release would not have been
! 58: possible if not for the hard work of Markus Veranen
! 59: <mailto:markus.veranen@gmail.com>
! 60:
! 61: Tested on Ubuntu 14.04 (GLIBC/Linux 3.13), Debian 8.1 (GLIBC/Linux
! 62: 3.16), FreeBSD, NetBSD, and OpenBSD.
! 63:
! 64: ** Changes and New Features
! 65: - Support for PIM-SSM and IGMPv3, by Markus Veranen
! 66: - IGMPv3 is now default, use =phyint ifname igmpv2= for old behaviour
! 67: - Default IGMP query interval has changed from 125 sec to 12 sec
! 68:
! 69: In =pimd.conf: igmp-query-interval <SEC>=
! 70:
! 71: - Default IGMP querier timeout has changed from 255 sec to 42 sec
! 72:
! 73: In =pimd.conf: igmp-querier-timeout <SEC>=
! 74:
! 75: - The built-in IGMP /robustness value/ changed from 2 to 3
! 76: - Support for changing the PIM Hello interval, by Markus Veranen
! 77:
! 78: In =pimd.conf: hello-interval <SEC>=
! 79:
! 80: - Support for multiple multicast routing tables, and running multiple
! 81: pimd instances, by Markus Veranen. (Only supported on Linux atm.)
! 82: - Support for advertising, and acting upon changes to, Generation ID
! 83: in PIM Hello messages, by Markus Veranen
! 84: - Support for advertising /DR Priority/ option in PIM Hello messages.
! 85: If all routers on a LAN send this option this value is used in the
! 86: DR election rather than the IP address. The priority is configured
! 87: per =phyint=. This closes the long-standing issue #5.
! 88: - Distribution archive format changed from XZ to Gzip, for the benefit
! 89: of OpenBSD that only ships Gzip in the base system.
! 90:
! 91: ** New pimd.conf syntax!
! 92:
! 93: The =pimd.conf= syntax has been changed in this release. Mainly, the
! 94: configuration file now use dashes =-= instead of underscore =_= as word
! 95: separators. However several settings have also been renamed to be more
! 96: familiar to commands used by major router vendors:
! 97:
! 98: - =bsr-candidate= :: replaces =cand_bootstrap_router=
! 99: - =rp-candidate= :: replaces =cand_rp=
! 100: - =group-prefix= :: replaces =group_prefix=
! 101: - =rp-address= :: replaces =rp_address=
! 102: - =spt-threshold= :: replaces the two deprecated
! 103: =switch_register_threshold= and =switch_data_threshold= settings
! 104: - =hello-interval= :: replaces =hello_period=
! 105: - =default-route-distance= :: replaces =default_source_preference=
! 106: - =default-route-metric= :: replaces =default-source-metric=
! 107:
! 108: Also, for =phyint= the =preference= sub-option has been replaced with
! 109: the less confusing =distance= and =ttl-threshold= replaces =threshold=.
! 110: See the README or the man page for more information on the metric
! 111: preference and admin distance confusion.
! 112:
! 113: /*Note:* The =pimd.conf= parser remains backwards compatible with the
! 114: old syntax!/
! 115:
! 116:
! 117: ** Compile Time Features
! 118:
! 119: The following are new features that must be enabled at compile time,
! 120: using the =configure= script, to take effect. For details, see
! 121: =./configure --help=
! 122:
! 123: - =--prefix=PATH= :: Standard prefix to be used at installation,
! 124: default =/usr/local=
! 125: - =--sysconfdir=PATH= :: Prefix path to be used for =pimd.conf=,
! 126: default =/etc=, unless =--prefix= is given.
! 127: - =--embedded-libc= :: Enable uClib or musl libc build, on Linux.
! 128: - =--disable-exit-on-error= :: Allow pimd to continue running despite
! 129: encountering errors.
! 130: - =--disable-pim-genid= :: Disable advertisement of PIM Hello GenID,
! 131: use for compatibility problems with older versions of pimd.
! 132: - =--with-max-vifs=MAXVIFS= :: Raise max number of VIFs to MAXVIFS.
! 133:
! 134: *Note:* this requires raising MAXVIFS in the kernel as well!
! 135: Most kernels cannot handle >255, if this is a problem, try using
! 136: multiple multicast routing tables instead.
! 137: - =--disable-masklen-check= :: Allow tunctl VIFs with masklen 32.
! 138:
! 139:
! 140: ** Bug Fixes
! 141: - Fix issue #40: FTBS with =./configure --enable-scoped-acls=
! 142: - Properly support cross compiling. It is now possible to actually
! 143: define the =$CROSS= environment variable when calling =make= to
! 144: allow cross compiling pimd. Should work with both GCC and Clang.
! 145: Tested on Ubuntu, Debian and FreeBSD.

! 147: #+LATEX: \newpage
! 148: * Version 2.2.1: April 20, 2015
! 149: ** Bug Fixes
! 150: - Fix another problem with issue #22 (reopened), as laid out in
! 151: issue #37. This time the crash is induced when there is a link down
! 152: event. Lot of help debugging the propblem by @mfspeer, who also
! 153: suggested the fix -- to call =pim_proto.c:delete_pim_nbr()= in
! 154: =vif.c:stop_vif()= instead of just calling free.
! 155: - Fix issue with not checking return value of =open()= in daemonizing
! 156: code in =main()=, found by Coverity Scan.
! 157: - Fix issue with scoped =phyint= in =config.c=, found by Coverity Scan.
! 158: The =masklen= may not be zero, config file problem, alert the user.
! 159:
! 160:
! 161: #+LATEX: \newpage

! 179: =cand_bootstrap_router=
! 180: - Add new =spt_threshold= to replace existing =switch_register_threshold=
! 181: and =switch_data_threshold settings=. Cisco-like and easier to understand
! 182:
! 183: ** Bug Fixes
! 184: - Fix to avoid infinite loop during unicast send failure, by Alex Tessmer
! 185: - Fix bug in bootstrap when configured as candidate RP, issue #15
! 186: - Fix segfault in =accept_igmp()=, issue #29
! 187: - Fix default source preference, should be 101 (not 1024!)
! 188: - Fix =ip_len= handling on older BSD's, thanks to Olivier

! 199: #+LATEX: \newpage
! 200: * Version 2.1.8: October 22, 2011
! 201: ** Changes & New Features
! 202: - Update docs of static Rendez-Vous Point, =rp_address=, configuration
! 203: in man page and example =pimd.conf=. Thanks to Andriy Senkovych
! 204: <mailto:andriysenkovych@gmail.com> and YAMAMOTO Shigeru <mailto:shigeru@iij.ad.jp>
! 205:
! 206: - Replaced =malloc()= with =calloc()= to mitigate risk of accessing
! 207: junk data and ease debugging. Thanks to YAMAMOTO Shigeru
! 208: <mailto:shigeru@iij.ad.jp>
! 209:
! 210: - Extend .conf file =rp_address= option with =priority= field. Code
! 211: changes and documentation updates by YAMAMOTO Shigeru
! 212: <mailto:shigeru@iij.ad.jp>
! 213:
! 214: ** Bug Fixes
! 215: - A serious bug in =pim_proto.c:receive_pim_register()= was found and
! 216: fixed by Jean-Pascal Billaud. In essence, the RP check was broken
! 217: since the code only looked at =my_cand_rp_address=, which is not set
! 218: when using the =rp_address= config. Everything works fine with
! 219: auto-RP mode though. This issue completely breaks the register path
! 220: since the JOIN(S,G) is never sent back ...
! 221:
! 222: - Fix FTBFS issues reported from Debian. Later GCC versions trigger unused
! 223: variable warnings. Patches and cleanup Antonin Kral <mailto:a.kral@bobek.cz>
! 224:
! 225: * Version 2.1.7: January 9, 2011
! 226: ** Changes & New Features
! 227: - The previous move of runtime dump files to =/var/lib/misc= have been
! 228: changed to =/var/run/pimd= instead. This to accomodate *BSD systems
! 229: that do not have the =/var/lib= tree, and also recommended in the
! 230: Filesystem Hierarchy Standard,
! 231: http://www.pathname.com/fhs/pub/fhs-2.3.html#VARRUNRUNTIMEVARIABLEDATA
! 232:
! 233:
! 234: #+LATEX: \newpage
! 235: * Version 2.1.6: January 8, 2011
! 236: ** Changes & New Features
! 237: - Debian package now conflicts with =smcroute=, in addition to
! 238: =mrouted=. It is only possible to run one multicast routing daemon
! 239: at a time, kernel limitation.
! 240:
! 241: - The location of the dump file(s) have been moved from =/var/tmp= to
! 242: =/var/lib/misc= due to the insecure nature of =/var/tmp=. See more
! 243: below.
! 244:
! 245: ** Bug Fixes
! 246: - =kern.c:k_del_vif()=: Fix build error on GNU/kFreeBSD
! 247:
! 248: - CVE-2011-0007: Insecure file creation in =/var/tmp=. "On USR1, pimd
! 249: will write to =/var/tmp/pimd.dump= a dump of the multicast route
! 250: table. Since =/var/tmp= is writable by any user, a user can create
! 251: a symlink to any file he wants to destroy with the content of the
! 252: multicast routing table."
! 253:
! 254: * Version 2.1.5: November 21, 2010
! 255: ** Changes & New Features
! 256: - Improved error messages in kern.c
! 257: - Renamed CHANGES to ChangeLog
! 258:
! 259: ** Bug Fixes
! 260: - Import mrouted fix: on GNU/Linux systems (only!) the call to
! 261: =kern.c:k_del_vif()= fails with: =setsockopt MRT_DEL_VIF on vif 3:
! 262: Invalid argument=. This is due to differences in the Linux and *BSD
! 263: =MRT_DEL_VIF= API. The Linux kernel expects to receive a =struct
! 264: vifctl= associated with the VIF to be deleted, *BSD systems on the
! 265: other hand expect to receive the index of that VIF.
! 266:
! 267: Bug reported and fixed on mrouted by Dan Kruchinin <mailto:dkruchinin@acm.org>
! 268:
! 269:

! 284: - Cleanup and ansification of a couple of files: rp.c, mrt.c, vif.c, route.c
! 285:
! 286: - Initialize stack variables to silence overzealous GCC on PowerPC and S/390.
! 287: Debian bug 595584, this closes pimd issue #3 on GitHub.

! 289: ** Bug Fixes
! 290: - Merge bug fix for static-rp configurations from Kame's pim6sd route.c r1.28
! 291:
! 292: - Close TODO item by merging in relevant changes from Kame's pim6sd =vif.c r1.3=

! 417: - PIM join does not go upstream. Bug report and fix by SUZUKI Shinsuke
! 418: <mailto:suz@crl.hitachi.co.jp>; incorporated back from pim6sd.
! 419: #+BEGIN_EXAMPLE
! 420: [problem]
! 421: PIM join does not go upstream in the following topology, because oif-list
! 422: is NULL after subtracting iif from oif-list.
! 423:
! 424: receiver---rtr1---|
! 425: rtr2---|---rtr3----sender
! 426:
! 427: rtr1's nexthop to sender = rtr2
! 428: rtr2's nexthop to sender = rtr3
! 429:
! 430: [reason]

! 505: Asaeda <mailto:asaeda@yamato.ibm.com>
! 506:
! 507: * Version 2.1.0-alpha29.7: September 10, 2001
! 508: ** Changes & New Features
! 509: - Added "phyint altnet" (see pimd.conf for usage) for allowing some senders look
! 510: like directly connected to a local subnet. Implemented by Marian Stagarescu
! 511: <mailto:marian@bile.cidera.com>
! 512:
! 513: - Added "phyint scoped" (see pimd.conf for usage) for administartively disabling
! 514: the forwarding of multicast groups. Implemented by Marian Stagarescu
! 515: <mailto:marian@bile.cidera.com>
! 516:
! 517: - The License has changed from the original USC to the more familiar BSD-like (the
! 518: KAME+OpenBSD guys brought to my attention that the original working in the USC
! 519: license "...and without fee..." is ambiguous and makes it sound that noone can
! 520: distribute pimd as part of some other software distribution and charge for that
! 521: distribution.
! 522:
! 523: - RSRR disabled by default in Makefile
! 524:

! 549: ** Changes & New Features
! 550: - =VIFM_FORWARDER()= macro renamed to =VIFM_LASTHOP_ROUTER=.
! 551:
! 552: - Mini-FAQ entries added to README.
! 553:
! 554: ** Bug Fixes
! 555: - When there is a new member, =add_leaf()= is called by IGMP code for any router,
! 556: not only for a DR. The reason is because not only the DR must know about local
! 557: members, but the last-hop router as well (so eventually it will initiate a SPT
! 558: switch). Similar fixes to =add_leaf()= inside route.c as well. Problem
! 559: reported by Hitoshi Asaeda <mailto:asaeda@yamato.ibm.com>. XXX: Note the
! 560: lenghty comment in the beginning of =add_leaf()= about a pimd desing problem
! 561: that may result in SPT switch not initiated immediately by the last-hop router.
! 562:
! 563: - DR entry timer bug fix in timer.c: When (*,G)'s iif and (S,G)'s iif are not
! 564: same, (S,G)'s timer for the DR doesn't increase. Reported indirectly by
! 565: <mailto:toshiaki.nakatsu@fujixerox.co.jp>
! 566:
! 567: * Version 2.1.0-alpha29.4: December 1, 2000

! 577: thanks to Hitoshi Asaeda <mailto:asaeda@yamato.ibm.co.jp>.
! 578:

! 581: <mailto:asaeda@yamato.ibm.co.jp> & (indirectly)
! 582: <mailto:toshiaki.nakatsu@fujixerox.co.jp>
! 583:
! 584: - =pim_proto.c=: Two critical bug fixes. J/P prune suppression related message
! 585: and J/P message with (*,*,RP) entry inside. Thanks to Azzurra Pantella
! 586: <mailto:s198804@studenti.ing.unipi.it> and Nicola Dicosmo from University of
! 587: Pisa
! 588:
! 589: - =pim_proto.c:receive_pim_bootstrap()=: BSR-related fix from Kame's pim6sd.
! 590: Even when the BSR changes, just schedule an immediate advertisemnet of C-RP-ADV,
! 591: instead of sending message, in order to avoid sending the advertisement to the
! 592: old BSR. In response to comment from <mailto:toshiaki.nakatsu@fujixerox.co.jp>
! 593:
! 594: * Version 2.1.0-alpha29.3: October 13, 2000

! 597: thanks to Eric S. Johnson <mailto:esj@cs.fiu.edu>
! 598:
! 599: * Version 2.1.0-alpha29.2: October 13, 2000
! 600: NB: THIS pimd VERSION WON'T WORK WITH OLDER PIM-SM KERNEL PATCHES (kernel
! 601: patches released prior to this version)!
! 602:
! 603: ** Changes & New Features
! 604: - The daemon that the kernel will prepare completely the inner multicast packet for
! 605: PIM register messages that the kernel is supposed to encapsulate and send to the
! 606: RP.
! 607:
! 608: - Now pimd compiles on OpenBSD-2.7. PIM control messages exchange test passed.
! 609: Ddon't have the infrastructure to perform more complete testing.
! 610:
! 611: - =main.c:cleanup()=: Send =PIM_HELLO= with holdtime of '0' if pimd is going away,
! 612: thanks to JINMEI Tatuya <mailto:jinmei@isl.rdc.toshiba.co.jp>
! 613:
! 614: - =include/netinet/pim.h= updated
! 615:
! 616: - pimd code adapted to the new =struct pim= definition.
! 617:
! 618: - Added =PIM_OLD_KERNEL= and =BROKEN_CISCO_CHECKSUM= entries in the Makefile.
! 619:
! 620: - Don't ignore kernel signals if any of src or dst are NULL.
! 621:
! 622: - Don't touch =ip_id= on a PIM register message
! 623:
! 624: - README cleanup: kernel patches location, obsoleted systems clarification, etc.
! 625:
! 626: - =k_stop_pim()= added to =cleanup()= in =main.c= (courtesy Kame)
! 627:
! 628: ** Bug Fixes
! 629: - =RANDOM()=-related bug fix re. =jp_value= calculation in =pim_proto.c=,

! 647: - VIF name string comparison fix in =routesock.c:getmsg()= courtesy of the Kame
! 648: project
! 649:
! 650: - missing brackets added inside =age_routes()= (a bug that will show up
! 651: only if =KERNEL_MFC_WC_G= was defined); courtesy of the Kame project
! 652:
! 653: * Version 2.1.0-alpha28: March 15, 2000
! 654:
! 655: ** Changes & New Features
! 656: - added #ifdef =BROKEN_CISCO_CHECKSUM= (disabled by default) to make cisco RPs
! 657: happy (read the comments in pim.c)
! 658:
! 659: - added #ifdef =PIM_TYPEVERS_DECL= in netinet/pim.h as a workaround that ANSI-C
! 660: doesn't guarantee that bit-fields are tightly packed together (although all
! 661: modern C compilers should not create a problem).
! 662:
! 663: ** Bug Fixes
! 664: - Fixes to enable point-to-point interfaces being added correctly, thanks to
! 665: Roger Venning <mailto:Roger.Venning@corpmail.telstra.com.au>
! 666:
! 667: - A number of minor bug fixes
! 668:
! 669: * Version 2.1.0-alpha27: January 21, 2000
! 670: NB: this release may the the last one from 2.1.0. The next release will be 2.2.0 and
! 671: there will be lots of changes inside.
! 672:
! 673: ** Bug Fixes
! 674: - Bug fix in =rp.c:add_grp_mask()= and =rp.c:delete_grp_mask()=: in some cases if
! 675: the RPs are configured with nested multicast prefixes, the add/delete may
! 676: fail. Thanks to Hitoshi Asaeda and the KAME team for pointing out this one.
! 677:
! 678: * Version 2.1.0-alpha26: October 28, 1999
! 679: ** Bug Fixes
! 680: - Bug fix in =receive_pim_register()= in =pim_proto.c:ntohl()= was missing
! 681: inside =IN_MULTICAST()=. Thanks to Fred Griffoul <mailto:griffoul@ccrle.nec.de>
! 682:
! 683: - Bug report and fix by Hitoshi Asaeda <mailto:asaeda@yamato.ibm.co.jp> in
! 684: =pim_proto.c:receive_pim_cand_rp_adv()= (if a router is not a BSR). Another bug
! 685: in =rp.c:delete_grp_mask_entry()=: an entry not in the head of the list was not
! 686: deleted propertly.
! 687:
! 688: - Some =VIFF_TUNNEL= checks added or deleted in various places. Slowly preparing
! 689: pimd to be able to work with GRE tunnels...
! 690:
! 691: * Version 2.1.0-alpha25: August 30, 1999
! 692: Bug reports and fixes by Hitoshi Asaeda <mailto:asaeda@yamato.ibm.co.jp> inside
! 693: =parse_reg_threshold()= and =parse_data_threshold()= in config.c
! 694:
! 695: ** Changes & New Features
! 696: - Successfully added multicast prefixes configured in pimd.conf are displayed at
! 697: startup
! 698:
! 699: - Use =include/freebsd= as FreeBSD-3.x include files and =include/freebsd2= for
! 700: FreeBSD-2.x.
! 701:
! 702: ** Bug Fixes
! 703: - Test is performed whether a =PIM_REGISTER= has invalid source and/or group
! 704: address of the internal packet.
! 705:
! 706: * Version 2.1.0-alpha24: August 9, 1999
! 707: ** Changes & New Features
! 708: - =PIM_DEFAULT_CAND_RP_ADV_PERIOD= definition set to 60, but default 'time' value
! 709: for inter Cand-RP messages is set in pimd.conf to 30 sec.
! 710:
! 711: - =PIM_REGISTER= checksum verification in =receive_pim_register()= relaxed for
! 712: compatibility with some older routers. The checksum has to be computed only over
! 713: the first 8 bytes of the PIM Register (i.e. only over the header), but some older
! 714: routers might compute it over the whole packet. Hence, the checksum verification
! 715: is over the first 8 bytes first, and if if it fails, then over the whole
! 716: packet. Thus, pimd that is RP should still work with older routers that act as
! 717: DR, but if an older router is the RP, then pimd cannot be the DR. Sorry, don't
! 718: know which particular routers and models create the checksum over the whole PIM
! 719: Register (if there are still any left).
! 720:
! 721: * Version 2.1.0-alpha23: May 24, 1999
! 722: ** Changes & New Features
! 723: - Finally pimd works under Linux (probably 2.1.126, 2.2.x and 2.3.x). However, a

! 844: - allpimrouters deleted from igmp.c (already defined in pim.c)
! 845:
! 846: - igmpmsg defined for IRIX
! 847:
! 848: * Version 2.1.0-alpha17: May 21, 1998
! 849: ** Changes & New Features
! 850: - (*,G) MFC kernel support completed and verified. Compile with =KERNEL_MFC_WC_G=
! 851: defined in Makefile, but then must use it only with a kernel that supports (*,G),
! 852: e.g. =pimkern-PATCH_7=. Currently, kernel patches available for FreeBSD and
! 853: SunOS only.
! 854:
! 855: ** Bug Fixes
! 856: - =MRTF_MFC_CLONE_SG= flag set after =delete_single_kernel_cache()= is called
! 857:
! 858: * Version 2.1.0-alpha16: May 19, 1998
! 859: ** Changes & New Features
! 860: - PIM registers kernel encapsulation support. Build with =PIM_REG_KERNEL_ENCAP=
! 861: defined in Makefile.
! 862:
! 863: - (*,G) MFC support. Build with =KERNEL_MFC_WC_G= defined in Makefile. However,
! 864: =MFC_WC_G= is still not supported with =pimkern-PATCH_6=, must disable it for now.
! 865:
! 866: - =mrt.c:delete_single_kernel_cache_addr()=: New function, uses source, group to
! 867: specify an MFC to be deleted
! 868:
! 869: * Version 2.1.0-alpha15: May 14, 1998
! 870: - Another few bug fixes related to NetBSD definitions thanks to Heiko W.Rupp
! 871: <mailto:hwr@pilhuhn.de>
! 872:
! 873: * Version 2.1.0-alpha14: May 12, 1998
! 874: - A few bug fixes related to NetBSD definitions thanks to Heiko W.Rupp
! 875: <mailto:hwr@pilhuhn.de>
! 876:
! 877: * Version 2.1.0-alpha13: May 11, 1998
! 878: ** Changes & New Features
! 879: - If the RP changes, the necessary actions are taken to pass the new RP address to
! 880: the kernel. To be used for kernel register encap. support. Wnat needs to be done
! 881: is: (a) add =rp_addr= entry to the mfcctl structure, and then just set it in
! 882: =kern.c:k_chf_mfc()=. Obviously, the kernel needs to support the register
! 883: encapsulation (instead of sending WHOLEPKT to the user level). In the near few
! 884: days will make the necessary kernel changes.
! 885:
! 886: - =change_interfaces()=: Added "flags" argument. The only valid flag is
! 887: =MFC_UPDATE_FORCE=, used for forcing kernel call when only the RP changes.
! 888:
! 889: - =k_chg_mfc()= has a new argument: rp_addr. To be used for kernel register
! 890: encapsulation support
! 891:
! 892: - =MRT_PIM= completely replaced by =MRT_ASSERT=
! 893:
! 894: - =move_kernel_cache()=: Argument =MFC_MOVE_FORCE= is a flag instead of TRUE/FALSE
! 895:
! 896: - =process_cache_miss()=: removed unneeded piece of code
! 897:
! 898: * Version 2.1.0-alpha12: May 10, 1998
! 899: ** Changes & New Features
! 900: - Use the cleaned up =netinet/pim.h=
! 901:
! 902: - Remove the no needed anymore pim header definition in =pimd.h=
! 903:
! 904: - Don't use =MRT_PIM= in in kern.c anymore, replaced back with =MRT_ASSERT=.
! 905:
! 906: - =added default_source_metric= and =default_source_preference= (1024) because the
! 907: kernel's unicast routing table is not a good source of info; configurable in
! 908: pimd.conf
! 909:
! 910: - Can now compile under NetBSD-1.3, thanks to Heiko W.Rupp <mailto:hwr@pilhuhn.de>
! 911:
! 912: ** Bug Fixes
! 913: - Incorrect setup of the borderBit and nullRegisterBit (different for big and
! 914: little endian machines) fixed; =*_BORDER_BIT= and =*NULL_REGISTER_BIT= redefined
! 915:
! 916: - don't send =pim_assert= on tunnels or register vifs (if for whatever reason we
! 917: receive on such interface)
! 918:
! 919: - ignore =WRONGVIF= messages for register and tunnel vifs (the cleaned up
! 920: kernel mods dont send such signal, but the older (before May 9 '98) pimd
! 921: mods that signaling was enabled
! 922:
! 923: * Version 2.1.0-alpha11: March 16, 1998

! 925: - =vif.c:find_vif_direct_local()=: New function, used in =routesock.c=, =igmp_proto.c=
! 926:
! 927: - Use =MFC_MOVE_FORCE/MFC_MOVE_DONT_FORCE= flag in =mrt.c=, =route.c=,
! 928: =pim_proto.c=, when need to move the kernel cache entries between (*,*,RP),
! 929: (*,G), (S,G)
! 930:
! 931: - new timer related macros: =SET_TIMER()=, =FIRE_TIMER()=, =IF_TIMER_SET()=,

! 950: - =timer.c:age_routes()=: now (S,G) entry with local members (inherited from
! 951: (*,G)) is timeout propertly
! 952:
! 953: - =timer.c:age_routes()=: (S,G) J/P timer restarted propertly
! 954:
! 955: - =timer.c:age_routes()=: check also the (S,G)RPbit entries in the forwarders and
! 956: RP and eventually switch to the shortest path if data rate too high
! 957:
! 958: - =route.c:process_wrong_vif()= fire J/P timer
! 959:
! 960: - =route.c:switch_shortest_path()=: reset the iif toward S if there is already
! 961: (S,G)RPbit entry
! 962:
! 963: * Version 2.1.0-alpha10: March 3, 1998
! 964: Temp. non-public release.
! 965:
! 966: ** Changes & New Features
! 967: - `interval` can be applied for data rate check. The statement in =pimd.conf=
! 968: that only the default value will be used is not true anymore.

! 971: can be different.
! 972:
! 973: - =pim_proto.c:receive_pim_register()=: check if I am the RP for that group,

! 981: address is the corresponding one for the given mrtentry
! 982:
! 983: - =debug.c:dump_mrt()= timer values added
! 984:

! 988: - =DEBUG_DVMRP_DETAIL= and =DEBUG_PIM_DETAIL= added
! 989:
! 990: ** Bug Fixes
! 991: - =mrt.c:add_kernel_cache()=: no kernel cache duplicates
! 992:
! 993: - =mrt.c:move_kernel_cache()=: if the iif of the (*,*,R) (or (*,G))
