2011-07-05bgpd: Remove AS Path limit/TTL functionalityPaul Jakma
* draft-ietf-idr-as-pathlimit doesn't seem to have gone anywhere, and its author does not think it will make progress in IDR. Remove all support introduced for it, but leave stubs for the commands to avoid breaking any configurations. Basically reverts cecab5e9725792e60a5e4b473e238a14cd85815d. (cherry picked from commit c8f3fe3063cb9ff193b13011cfbda3e605395340) Conflicts: bgpd/bgp_attr.c (caused by c8e7b895, resolved)
2011-07-04bgpd/security: CVE-2010-1674 Fix crash due to extended-community parser errorPaul Jakma
* bgp_attr.c: (bgp_attr_ext_communities) Certain extended-community attrs can leave attr->flag indicating ext-community is present, even though no extended-community object has been attached to the attr structure. Thus a null-pointer dereference can occur later. (bgp_attr_community) No bug fixed here, but tidy up flow so it has same form as previous. Problem and fix thanks to anonymous reporter. (cherry picked from commit 0c46638122f10019a12ae9668aec91691cf2e017)
2011-07-04bgpd: VTY string fixes for debug commandsDavid Ward
* bgpd/bgp_debug.c: fix VTY strings for BGP debug commands to match correct syntax (cherry picked from commit 6e22b9017e1ae2ce61c383b1b2b63973207704ac)
2011-07-04bgpd: fix handling of "Unsupported Capability"Dmitrij Tejblum
* bgp_packet.c: (bgp_notify_receive) justify the difference between BGP_NOTIFY_OPEN_UNSUP_PARAM and BGP_NOTIFY_OPEN_UNSUP_CAPBL cases, as it is explained in RFC5492, page 3, paragraph 1. "Unsupported Capability" error does not mean, that the peer doesn't support capabilities advertisement -- quite the opposite (if the peer would not support capabilities advertisement, the code would be "Unsupported Optional Parameter"). Thus there is no reason to mark the peer as one non-supporting capabilities advertisement. Example: suppose the peer is in fact IPv6-only, but we didn't configure anything address-family specific for it. Then, the peer would refuse the session with "Unsupported Capability" code. If we internally set the peer as non-supporting capabilities advertisement after that, we will not be able to establish the session with it ever, even with a fixed configuration -- IPv6-only BGP session cannot be established without capabilities. In practice an edge case would be seen as the same IPv6 peer working with its "neighbor" block read from bgpd.conf, but not working, when slowly input in "conf t" mode. (cherry picked from commit c7aa8abd8788c3607ad0131f02e892cf92221e40)
2011-07-04bgpd: fix community-list error message spellingDenis Ovsienko
* bgp_vty.c: (community_list_perror, show_ip_community_list_arg, show_ip_extcommunity_list_arg) fix spelling (cherry picked from commit b729294c8c5c6f2af8ddf6cfbea2374b6faabe9d)
2010-10-21bgpd: fix printed value of last-update timestampVladimir L Ivanov
* bgp_route.c: (route_vty_out_detail) calculate time value in a way, which works regardless of monotonic clock being used or not

* bgpd/bgp_attr.c, bgpd/bgp_open.h, bgpd/bgp_route.c, lib/prefix.c, lib/prefix.h: Various integer types were being used where, if we had strict type checking, afi_t and safi_t would be required.

2010-09-17Set from even if binfo->extra is NULL.Greg Troxel
bgpd/bgp_packet.c:bgp_update_packet(): When extracting the peer, don't fail to extract it because "binfo->extra" is NULL. While one should certainly avoid dereferencing binfo->extra, that's not a good reason not to use binfo->peer. Fixes https://bugzilla.quagga.net/show_bug.cgi?id=497. Patch by Eric Sobocinksi.
2010-08-09bgpd: fix handling of AS path dataChris Hall
* bgpd/bgp_aspath.c * assegments_parse(): add handling of AS4_PATH input, update bounds checks, add check for AS segment type * aspath_parse(): add handling of AS4_PATH input, expect assegments_parse() to do length checking * aspath_empty(): update for the new function prototype * bgpd/bgp_aspath.h: ditto * tests/aspath_test.c: ditto * bgpd/bgp_attr.c * bgp_attr_aspath(): add handling of AS4_PATH input, update flags checks, change returned type * bgp_attr_as4_path(): discard, superseded by bgp_attr_aspath() * bgp_attr_parse(): update respectively
2010-05-14bgpd: tighten bounds checking in RR ORF msg readerChris Hall
* bgp_packet.c: (bgp_route_refresh_receive) add validation of "Length" (RFC5292) field value, check input stream bounds each time bytes are pulled from it
2010-01-15bgp: use monotonic clock for time of dayStephen Hemminger
BGP uses time() to get system time of day; but that value fluctuates with time adjustments from NTP. This can cause premature flapping of peer sessions and other failures.

2009-12-09lib: move check_bit into prefix common codeStephen Hemminger

2009-12-04bgpd: work around warning in assegments_parse()Denis Ovsienko
2009-08-28bgpd: fix md5 set on listen socketsStephen Hemminger
* bgp_network.c: (bgp_md5_set) Missing piece from earlier listener change did not get ported from Vyatta code into upstream. The list listener_sockets changed from (int *) to (struct bgp_listener *).
2009-08-13bgp: missing pieces from listener patchStephen Hemminger
* bgp_network.c: (bgp_accept) The code in current git will crash as part of the revised listener code is missing. The new listener thread code passes a pointer to a bgp_listener structure, not the bgp pointer. The old code always got a NULL for bgp pointer, so that is now hard coded.
2009-08-13bgp: compiler warning fixStephen Hemminger
* bgp_filter.h: Gcc complains the function prototype is not correct because the function argument is using old K&R style.
2009-08-05bgpd: Fix mistakes in applying 'allow inbound connections to non-default view'Paul Jakma
* bgpd.c: (peer_lookup_with_open) Bodged application of previous patch meant the second loop around bgp->peer wasn't included in the loop around bm->bgp as it was supposed to be. Fix..
2009-07-30[bgpd] delete erroneous extra brace..Paul Jakma
2009-07-30bgpd: Workaround for invalid MBGP next hopMichael Lambert
* bgp_attr.c: (bgp_mp_reach_parse) There are some interoperability issues for MBGP (particularly IPv4 multicast NLRI) between different implementations. In order to get some next hops to install correctly in the BGP tables, it appears to be necessary to copy the multiprotocol next hop into the base next hop field. This is related to differences in RFC 2283 and RFC 2858.
2009-07-28bgpd/trivial: Fix indentation in previousPaul Jakma
2009-07-28bgpd: Allow inbound connections to non-default viewSteve Hill
* bgpd.c: (peer_lookup) Search through all BGP instances for matches, not just the default instance, if no specific instance is given. (peer_lookup_with_open) same.
2009-07-28bgpd: fd leak in bgpdSteve Hill
* bgp_fsm.c: I have found an fd leak in bgpd that is caused by the 'new' Clearing state. I've been seeing it from hold timer failures, but it can also be triggered by other things. When Hold_Timer_expired fires in Established state, a notify is sent and BGP_Stop event queued. The fsm then transitions into Clearing state. That is the problem; When the BGP_Stop event is serviced, the state table says to ignore it while in Clearing. Thus bgp_stop is not called and the fd leaks. Previously the peer would be in Idle state, which correctly handles the BGP_Stop event. Fix by making bgp_stop safe to call from Clearing state, without losing ClearingCompleted events, and then ensuring it is called prior to transition from Clearing->Idle.
2009-07-28bgpd: Delete AS_CONFED_SEQUENCE when prepending an AS_SEQUENCE type segmentVasilis Tsiligiannis
AS_CONFED_SEQUENCE segment should always be deleted when prepending (e.g. with a route-map) an AS_SEQUENCE segment to an AS path. Otherwise, AS_CONFED_SEQUENCE will not be deleted later when updating EBGP peers (since it is not the leftmost segment) and will leak outside the confederation.
2009-07-28bgpd: Implement BGP confederation error handling (RFC5065, Par. 5)Vasilis Tsiligiannis
This patch implements BGP confederation error handling in Quagga as described in RFC5065, paragraph 5. * bgp_aspath.c: (aspath_confed_check, aspath_left_confed_check) new functions * bgp_attr.c: (bgp_attr_aspath_check) apply previous and NOTIFY if there's a problem.
2009-07-28bgpd: start listener on first instanceStephen Hemminger
Start BGP listener only after first instance is started. This helps the security if BGP is not used but daemon is started. It also addresses some issues like MD5 not working on listener unless IPV6 configured (because listener was not in list); as well as compiler warnings. * bgp_network.c: (bgp_listener) listen socket creation consolidated here (bgp_socket) Use bgp_listener * bgpd.c: (bgp_get) call bgp_socket on creation of first struct bgp. (bgp_init) remove bgp_socket call. * memtypes.c: Add MTYPE_BGP_LISTENER
2009-07-28bgpd: peer action table static/constStephen Hemminger
bgpd.c: (various tables) only used in one place and are immutable.
2009-07-27[bgpd] Restore ability of 'neighbor ... update-source' to take interface namePaul Jakma
* bgp_vty.c: (BGP_UPDATE_SOURCE_STR) Restore ability to accept arbitrary interface names for the 'neighbor ... update-source' command - shouldn't have been deleted. (BGP_UPDATE_SOURCE_STR) Add help for same.
2009-07-21[bgp] Fix nexthop reachability check on confederationsVasilis Tsiligiannis
* bgp_route.c: (bgp_update_main) Nexthop reachability should be checked for confederations too in case a prefix is received from more than one confederation peers.
2009-07-21[bgpd] fix typo made by paul in previous commitPaul Jakma
2009-07-21[bgpd] Avoid zombie accepted peer entriesTimo Teräs
Currently, when accepting the connection, it can be left as zombie, when the peer just initiates a connection, but never sends data (and the TCP connection end packets are lost). This happens because for accepted connections a temporary new peer entry is created until OPEN message is exchanged, and this temporary peer entry does not get the hold time parameter set at all. * bgp_network.c: (bgp_accept) Set hold time and keepalive values for ACCEPT peers.
2009-07-21[bgpd] Small buffer overrun in bgp_clear_node_queue_initNick Hilliard
* bgp_route.c: (bgp_clear_node_queue_init) fix buffer overrun.
2009-07-19[bgpd] Stability fixes including bugs 397, 492Chris Caputo
I've spent the last several weeks working on stability fixes to bgpd. These patches fix all of the numerous crashes, assertion failures, memory leaks and memory stomping I could find. Valgrind was used extensively. Added new function bgp_exit() to help catch problems. If "debug bgp" is configured and bgpd exits with status of 0, statistics on remaining lib/memory.c allocations are printed to stderr. It is my hope that other developers will use this to stay on top of memory issues. Example questionable exit: bgpd: memstats: Current memory utilization in module LIB: bgpd: memstats: Link List : 6 bgpd: memstats: Link Node : 5 bgpd: memstats: Hash : 8 bgpd: memstats: Hash Bucket : 2 bgpd: memstats: Hash Index : 8 bgpd: memstats: Work queue : 3 bgpd: memstats: Work queue item : 2 bgpd: memstats: Work queue name string : 3 bgpd: memstats: Current memory utilization in module BGP: bgpd: memstats: BGP instance : 1 bgpd: memstats: BGP peer : 1 bgpd: memstats: BGP peer hostname : 1 bgpd: memstats: BGP attribute : 1 bgpd: memstats: BGP extra attributes : 1 bgpd: memstats: BGP aspath : 1 bgpd: memstats: BGP aspath str : 1 bgpd: memstats: BGP table : 24 bgpd: memstats: BGP node : 1 bgpd: memstats: BGP route : 1 bgpd: memstats: BGP synchronise : 8 bgpd: memstats: BGP Process queue : 1 bgpd: memstats: BGP node clear queue : 1 bgpd: memstats: NOTE: If configuration exists, utilization may be expected. Example clean exit: bgpd: memstats: No remaining tracked memory utilization. This patch fixes bug #397: "Invalid free in bgp_announce_check()". This patch fixes bug #492: "SIGBUS in bgpd/bgp_route.c: bgp_clear_route_node()". My apologies for not separating out these changes into individual patches. The complexity of doing so boggled what is left of my brain. I hope this is all still useful to the community. This code has been production tested, in non-route-server-client mode, on a linux 32-bit box and a 64-bit box. Release/reset functions, used by bgp_exit(), added to: bgpd/bgp_attr.c,h bgpd/bgp_community.c,h bgpd/bgp_dump.c,h bgpd/bgp_ecommunity.c,h bgpd/bgp_filter.c,h bgpd/bgp_nexthop.c,h bgpd/bgp_route.c,h lib/routemap.c,h File by file analysis: * bgpd/bgp_aspath.c: Prevent re-use of ashash after it is released. * bgpd/bgp_attr.c: #if removed uncalled cluster_dup(). * bgpd/bgp_clist.c,h: Allow community_list_terminate() to be called from bgp_exit(). * bgpd/bgp_filter.c: Fix aslist->name use without allocation check, and also fix memory leak. * bgpd/bgp_main.c: Created bgp_exit() exit routine. This function frees allocations made as part of bgpd initialization and, to some extent, configuration. If "debug bgp" is configured, memory stats are printed as described above. * bgpd/bgp_nexthop.c: zclient_new() already allocates stream for ibuf/obuf, so bgp_scan_init() shouldn't do it too. Also, made it so zlookup is global so bgp_exit() can use it. * bgpd/bgp_packet.c: bgp_capability_msg_parse() call to bgp_clear_route() adjusted to use new BGP_CLEAR_ROUTE_NORMAL flag. * bgpd/bgp_route.h: Correct reference counter "lock" to be signed. bgp_clear_route() now accepts a bgp_clear_route_type of either BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. * bgpd/bgp_route.c: - bgp_process_rsclient(): attr was being zero'ed and then bgp_attr_extra_free() was being called with it, even though it was never filled with valid data. - bgp_process_rsclient(): Make sure rsclient->group is not NULL before use. - bgp_processq_del(): Add call to bgp_table_unlock(). - bgp_process(): Add call to bgp_table_lock(). - bgp_update_rsclient(): memset clearing of new_attr not needed since declarationw with "= { 0 }" does it. memset was already commented out. - bgp_update_rsclient(): Fix screwed up misleading indentation. - bgp_withdraw_rsclient(): Fix screwed up misleading indentation. - bgp_clear_route_node(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_node_queue_del(): Add call to bgp_table_unlock() and also free struct bgp_clear_node_queue used for work item. - bgp_clear_node_complete(): Do peer_unlock() after BGP_EVENT_ADD() in case peer is released by peer_unlock() call. - bgp_clear_route_table(): Support BGP_CLEAR_ROUTE_MY_RSCLIENT. Use struct bgp_clear_node_queue to supply data to worker. Add call to bgp_table_lock(). - bgp_clear_route(): Add support for BGP_CLEAR_ROUTE_NORMAL or BGP_CLEAR_ROUTE_MY_RSCLIENT. - bgp_clear_route_all(): Use BGP_CLEAR_ROUTE_NORMAL. Bug 397 fixes: - bgp_default_originate() - bgp_announce_table() * bgpd/bgp_table.h: - struct bgp_table: Added reference count. Changed type of owner to be "struct peer *" rather than "void *". - struct bgp_node: Correct reference counter "lock" to be signed. * bgpd/bgp_table.c: - Added bgp_table reference counting. - bgp_table_free(): Fixed cleanup code. Call peer_unlock() on owner if set. - bgp_unlock_node(): Added assertion. - bgp_node_get(): Added call to bgp_lock_node() to code path that it was missing from. * bgpd/bgp_vty.c: - peer_rsclient_set_vty(): Call peer_lock() as part of peer assignment to owner. Handle failure gracefully. - peer_rsclient_unset_vty(): Add call to bgp_clear_route() with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. * bgpd/bgp_zebra.c: Made it so zclient is global so bgp_exit() can use it. * bgpd/bgpd.c: - peer_lock(): Allow to be called when status is "Deleted". - peer_deactivate(): Supply BGP_CLEAR_ROUTE_NORMAL purpose to bgp_clear_route() call. - peer_delete(): Common variable listnode pn. Fix bug in which rsclient was only dealt with if not part of a peer group. Call bgp_clear_route() for rsclient, if appropriate, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - peer_group_get(): Use XSTRDUP() instead of strdup() for conf->host. - peer_group_bind(): Call bgp_clear_route() for rsclient, and do so with BGP_CLEAR_ROUTE_MY_RSCLIENT purpose. - bgp_create(): Use XSTRDUP() instead of strdup() for peer_self->host. - bgp_delete(): Delete peers before groups, rather than after. And then rather than deleting rsclients, verify that there are none at this point. - bgp_unlock(): Add assertion. - bgp_free(): Call bgp_table_finish() rather than doing XFREE() itself. * lib/command.c,h: Compiler warning fixes. Add cmd_terminate(). Fixed massive leak in install_element() in which cmd_make_descvec() was being called more than once for the same cmd->strvec/string/doc. * lib/log.c: Make closezlog() check fp before calling fclose(). * lib/memory.c: Catch when alloc count goes negative by using signed counts. Correct #endif comment. Add log_memstats_stderr(). * lib/memory.h: Add log_memstats_stderr(). * lib/thread.c: thread->funcname was being accessed in thread_call() after it had been freed. Rearranged things so that thread_call() frees funcname. Also made it so thread_master_free() cleans up cpu_record. * lib/vty.c,h: Use global command_cr. Add vty_terminate(). * lib/zclient.c,h: Re-enable zclient_free().
2009-07-19[bgpd] Fix compiler warnings related to MD5Chris Caputo
This patch fixes: bgp_network.c: In function 'bgp_md5_set': bgp_network.c:107: warning: cast from pointer to integer of different size bgp_network.c: In function 'bgp_socket': bgp_network.c:447: warning: cast to pointer from integer of different size
2009-07-17[bgpd] Bug #533: Fix crash with copy/pasted commands, inc 'no bgp ...'Paul Jakma
* bgpd.c: Removal of (struct bgp *) from the master list was being left to bgp_free time. This meant there was a window of time between bgp_delete and refcounts hitting 0 (e.g. routes to be processed) where bgp_lookup's could return a deleted (struct bgp *). (bgp_delete) This is the logical place where a (struct bgp *) should lose its visibility, so move the deletion from the bgp-master list to here, from bgp_free. Many thanks to Fritz Reichmann for his thorough debugging of the problem and testing of fixes and Chris Caputo for his further analysis.

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.
