2009-06-23[bgpd] review 32-bit AS-path hotfix for 0.99.12Denis Ovsienko
The patch by Chris Caputo, which was used to prepare 0.99.12 release, consists of three parts: 1. memory allocation fix itself 2. fix for warnings about constant variables 3. fix for printf format specs (%d was used instead of %u) It was confirmed later, that: a. a much simpler bugfix was available for memory allocation b. committed version of the bugfix wasn't optimal CPU-wise At this point I consider reasonable to revert the allocation portion of that patch and to replace it with the shorter version, which is: -#define ASN_STR_LEN (5 + 1) +#define ASN_STR_LEN (10 + 1) Other two parts of Mr. Caputo's patch remain intact.
2009-06-23Fix "show ip bgp dampened-paths" garbage output.Chris Caputo
* bgpd/bgp_damp.c: Make bgp_damp_reuse_time_vty() accept a buffer and length, rather than returning a local var buffer whose contents can get trounced. Remove duplicate BGP_UPTIME_LEN define. * bgpd/bgp_damp.h: bgp_damp_reuse_time_vty() prototype change. * bgpd/bgp_route.c: Provide bgp_damp_reuse_time_vty() with a buffer and length. Remove duplicate BGP_UPTIME_LEN define. This problem was noticed in 2005... http://hibernia.jakma.org/~paul/patches/quagga-test.diff ...but the fix didn't make it into the code.

2009-06-23Fixes to RFC2385/MD5 BGPChris Caputo
* bgpd/bgp_network.c: Fix MD5 listen in IPv4 version of bgp_socket() by adding listen socket to listen_sockets list so that MD5 passwords can get set. * lib/sockopt.c: (sockopt_tcp_signature) Fix bogus "% Error while applying TCP-Sig to session(s)" / "can't set TCP_MD5SIG option" startup error messages by not returning error when there isn't one.
2009-06-22[bgpd] Fix 'update-source' command: It doesn't accept interface namesPaul Jakma
* bgp_vty.c: BGP_UPDATE_SOURCE_STR define should only specify IP addresses, the underlying mechanisms won't do anything useful with interface names. Fix bug #527.
2009-06-19[configure] add configure support for PCRE Posix libraryJeremy Jackson
Debian tried unsuccessfully to build with libpcreposix. This adds proper support to autoconf/configure.ac for it. Based on the patch by C.J. Adams-Collier in bug #483. bgpd/bgp_{regex,routemap}.h: Pull in PCRE POSIX header if available.

2009-06-18[bgpd/cleanup] Make BGP FSM table read-only staticStephen Hemminger
The finite state machine table is immutable.
2009-06-18[bgpd] reference count the BGP instanceStephen Hemminger
When a BGP instance is deleted with lots of routes and neighbors it is possible for the peer rsclient queue to run after bgp_delete has been called. This would lead to bgpd crashing, see https://bugzilla.vyatta.com/show_bug.cgi?id=3436 The fix is to add reference counting to the BGP instance and defer actual freeing until all references are gone. This patch also fixes a memory leak where the self-reference peer instance was being created but never freed. The check in bgp_clear_route is no longer valid because it is possible for it to be called when peer is in Deleted state during cleanup.
2009-06-18[bgpd] Make declarations matchStephen Hemminger
These variables are const.
2009-06-12[cleanup] Make command nodes staticStephen Hemminger
The cmd_nodes used to configure vty, can mostly be static so (basic data hiding 101).

2009-06-02[snmp] Compiler warning fixes for when "--enable-snmp" is configured.Chris Caputo
Compiled on 32-bit and 64-bit linux gcc 4.1.2 platforms. No run-time testing on 32-bit and limited run-time testing on 64-bit.
2009-06-02[bgp] Fix crash on SIGHUP, deref of freed workqueuesSteve Hill
* lib/workqueue.c: free-ing workqueues had never been tested obviously, queue's thread was not being stopped * bgpd/bgpd.c: null out freed workqueues, to prevent acting on freed workqueues

2009-05-29[bgpd] 64-bit bugfix in community_del_val by Jeremy Jackson <jerj@coplanar.net>Andrew J. Schorr
* bgpd/bgp_community.c: (community_del_val) Fix bug in memcpy that was using the wrong size on architectures where a pointer is not 32 bits.
2009-05-08Fix bgp ipv4/ipv6 accept handlingStephen Hemminger
When bgp calls getaddrinfo, it gets both ipv6 and ipv4 addresses. Unless IPV6_ONLY is set on Linux, only the ipv6 bind will succeed, and the IPV4 connections will come in as mapped connections on the IPV6 socket.
2009-04-30[bgpd] AS4 bugfix by Chris Caputo <ccaputo@alt.net>Denis Ovsienko
* bgpd/bgp_aspath.c: (aspath_make_str_count) "assert (len < str_size)" was getting hit under certain 4-byte ASN conditions. New realloc strategy. * bgpd/bgp_aspath.c: (aspath_key_make) const warning fix. "%d" -> "%u" 4-byte ASN corrections. Prevent negative number when ASN is above 2^31.

2008-09-09[bgpd] Allow accepted peers to progress even if realpeer is in ConnectPaul Jakma
* bgpd/bgp_packet.c: (bgp_open_receive) Try fix the little race in the FSM, where a accept-peer that progress faster than realpeer gets closed down if realpeer is still just in Connect, by allowing the realpeer to be bgp_stop'ed and doing the regular swapping-of-FSM state.
2008-09-06[bgpd] Document the FSM dummy-peer race that sometimes afflicts session setupPaul Jakma
* bgp_packet.c: (bgp_open_receive) the accept-peer hack can sometimes cause a race between two peers that try to establish sessions to each other, causing session setup to fail when it should have succeeded. In the worst case, the race can 'loop', causing prolonged failure to establish sessions.

2008-08-23[vty] Add support for a 'restricted mode' with anonymous vty connectionsPaul Jakma
* lib/command.h: Add a RESTRICTED_NODE, intended for use with anonymous, 'no login' vtys, to provide a subset of 'view' mode commands. * lib/command.c: Add RESTRICTED_NODE bits, nothing special, just following VIEW_NODE. * lib/vty.c: (vty_auth) enable authentication should fall back to restricted/view node as appropriate. (vty_create) init vty's to restricted/view node as appropriate, for the 'no login' case. (vty_{no_,}restricted_mode_cmd) config commands to enable 'anonymous restricted' in vty configuration. (vty_config_write) 'anonymous restricted' config. (vty_init) Install some commands to restricted mode, and the 'anonymous restricted' config commands into VTY_NODE. * bgpd/*.c: Install some of the safe(r) BGP commands into 'restricted mode', i.e. lookup commands of non-sensitive data. Useful with looking-glass route-servers.

2008-08-15 Paul Jakma <paul.jakma@sun.com> * */*: Fix various problems flagged by Sun Studio compiler. - '<qualifier> <storage>' obsolescent in declarations - empty statements (';' after ALIAS definitions) - implicit declarations (e.g printstack in lib/log.c) - "\%" in printf string instead of "%%" - loops that return on the first iteration (legitimately, but compiler can't really know), e.g. bgp_routemap.c - internal declarations which mask prototypes.

2008-08-22[bgpd] Add 'bgp open-accept' option, to send OPEN immediately on accepted connsPaul Jakma
2007-08-31 Paul Jakma <paul.jakma@sun.com> * (general) Add 'bgp open-accept' option, to allow bgpd to send OPEN on accepted connections, i.e. to not wait till after collision-detect to send OPEN, which appears to be allowed in RFC4271. This may help speed up establishing sessions, or help avoid FSM problems with sessions to certain peers. Not enabled by default though.
