2011-12-06bgpd: store nexthop info for redistributed IPV6 routesStephen Hemminger
BGP was ignoring nexthop info for static and other redistributed routes for IPv6. Build extra attribute info to store the nexthop. See also: https://bugzilla.vyatta.com/show_bug.cgi?id=6073
2011-07-20bgpd: Modify the BGP to zebra route announcement to support multipathJosh Bailey
routes. Use a growable buffer (bgp_nexthop_buf) to collect nexthops that are included in the announcement. Use the BGP_INFO_MULTIPATH_CHG flag to trigger zebra announcement so zebra will be updated if the multipath set changes. Display all multipath nexthops in 'debug bgp zebra' output. * bgpd/bgp_main.c * bgp_exit(): Free bgp_nexthop_buf when exiting * bgpd/bgp_route.c * bgp_process_rsclient(): Clear BGP_INFO_MULTIPATH_CHG after processing * bgp_process_main(): Check BGP_INFO_MULTIPATH_CHG to trigger zebra announcement and clear aftr processing * bgpd/bgp_zebra.c * bgp_nexthop_buf: Growable buffer used to collect nexthops for zebra announcement * bgp_zebra_announce(): Grow bgp_nexthop_buf if needed. Include multipath count in zebra announcement and add all nexthops to bgp_nexthop_buf. Pass bgp_nexthop_buf data to zebra announcement. Added nexthops to debug output. * bgp_zebra_init(): Initialize bgp_nexthop_buf at startup * bgpd/bgp_zebra.h * BGP_NEXTHOP_BUF_SIZE: Default initial bgp_nexthop_buf size has room for 8 nexthops

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().

Implement non-blocking zclient I/O with buffering. * zclient.h (struct zclient): Add two fields to support non-blocking I/O: struct buffer *wb, and struct thread *t_write. (zclient_free): Remove function. (zebra_redistribute_send): Change 2nd arg from socket fd to struct zclient * (needed to support non-blocking I/O and buffering). (zclient_send_message): New function to send an arbitrary message with non-blocking I/O. * zclient.c (zclient_new): Create write buffer. (zclient_free): Remove unused function. (zclient_stop): Must cancel new t_write thread. Also, reset all buffers: ibuf, obuf, and wb. (zclient_failed): New helper function for typical error handling. (zclient_flush_data): New thread to flush queued data. (zclient_send_message): New function to send the message in zclient->obuf to zebra using non-blocking I/O and buffering. (zebra_message_send, zapi_ipv4_route, zapi_ipv6_route): Use new zclient_send_message function instead of calling writen. (zclient_start): Set socket non-blocking. Also, change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. (zebra_redistribute_send): Change 2nd arg to struct zclient *. Can now use zclient->obuf to assemble the message instead of allocating a temporary stream. And call zclient_send_message to send the message instead of writen. (zclient_read): Convert to support non-blocking I/O by using stream_read_try instead of deprecated stream_read. (zclient_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf6_zebra.c (ospf6_zebra_redistribute, ospf6_zebra_no_redistribute): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ospf_zebra.c (ospf_zebra_add): Call zclient_send_message instead of writen. * rip_zebra.c (rip_redistribute_set, rip_redistribute_unset, rip_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * ripng_zebra.c (ripng_redistribute_unset, ripng_redistribute_clean): Change 2nd arg to zebra_redistribute_send from zclient->sock to zclient. * bgp_zebra.c (bgp_redistribute_set, bgp_redistribute_unset): The 2nd arg to zebra_redistribute_send is now zclient instead of zclient->sock. * isis_zebra.h (isis_zebra_finish): Remove declaration of unused function. * isis_zebra.c (isis_zebra_route_add_ipv4): Call zclient_send_message to send the message to zebra instead of calling writen directly, since zclient_send_message understands non-blocking I/O and will manage the buffer queue appropriately. (isis_zebra_finish): Remove unused function, particularly since the zclient_free function has been removed.
2005-04-072005-04-07 Paul Jakma <paul.jakma@sun.com>paul
* (global): Fix up list loops to match changes in lib/linklist, and some basic auditing of usage. * configure.ac: define QUAGGA_NO_DEPRECATED_INTERFACES * HACKING: Add notes about deprecating interfaces and commands. * lib/linklist.h: Add usage comments. Rename getdata macro to listgetdata. Rename nextnode to listnextnode and fix its odd behaviour to be less dangerous. Make listgetdata macro assert node is not null, NULL list entries should be bug condition. ALL_LIST_ELEMENTS, new macro, forward-referencing macro for use with for loop, Suggested by Jim Carlson of Sun. Add ALL_LIST_ELEMENTS_RO for cases which obviously do not need the "safety" of previous macro. LISTNODE_ADD and DELETE macros renamed to ATTACH, DETACH, to distinguish from the similarly named functions, and reflect their effect better. Add a QUAGGA_NO_DEPRECATED_INTERFACES define guarded section with the old defines which were modified above, for backwards compatibility - guarded to prevent Quagga using it.. * lib/linklist.c: fix up for linklist.h changes. * ospf6d/ospf6_abr.c: (ospf6_abr_examin_brouter) change to a single scan of the area list, rather than scanning all areas first for INTER_ROUTER and then again for INTER_NETWORK. According to 16.2, the scan should be area specific anyway, and further ospf6d does not seem to implement 16.3 anyway.

Fix problems when netlink interfaces are renamed (same ifindex used for a new interface). Start cleaning up some problems with the way interface names are handled. * interface.c: (if_new_intern_ifindex) Remove obsolete function. (if_delete_update) After distributing the interface deletion message, set ifp->ifindex to IFINDEX_INTERNAL. (if_dump_vty) Detect pseudo interface by checking if ifp->ifindex is IFINDEX_INTERNAL. (zebra_interface) Check return code from interface_cmd.func. Do not set internal ifindex values to if_new_intern_ifindex(), since we now use IFINDEX_INTERNAL for all pseudo interfaces. * kernel_socket.c: (ifm_read) Fix code and comments to reflect that all internal interfaces now have ifp->ifindex set to IFINDEX_INTERNAL. * rt_netlink.c: (set_ifindex) New function used to update ifp->ifindex. Detects interface rename events by checking if that ifindex is already being used. If it is, delete the old interface before assigning the ifindex to the new interface. (netlink_interface, netlink_link_change) Call set_ifindex to update the ifindex. * if.h: Remove define for IFINDEX_INTERNBASE and add define IFINDEX_INTERNAL 0, since all internal (i.e. non-kernel) pseudo- interfaces should have ifindex set to 0. (if_new) Remove function. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (ifname2ifindex) New function. * if.c: (if_new) Remove function (absorb into if_create). (if_create) Replace function if_new with call to calloc. Set ifp->ifindex to IFINDEX_INTERNAL. Fix off-by-one error in assert to check length of interface name. Add error message if interface with this name already exists. (if_delete_retain) New function to delete an interface without removing from iflist and freeing the structure. (if_delete) Implement with help of if_delete_retain. (ifindex2ifname) Reimplement using if_lookup_by_index. (ifname2ifindex) New function to complement ifindex2ifname. (interface) The interface command should check the name length and fail with a warning message if it is too long. (no_interface) Fix spelling in warning message. (if_nametoindex) Reimplement using if_lookup_by_name. (if_indextoname, ifaddr_ipv4_lookup) Reimplement using if_lookup_by_index. * bgp_zebra.c: (bgp_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * isis_zebra.c: (isis_zebra_if_del) Call if_delete_retain instead of if_delete, since it is generally not safe to remove interface structures. After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Tighten up code. * ospf6_zebra.c: (ospf6_zebra_if_del) Previously, this whole function was commented out. But this is not safe: we should at least update the ifindex when the interface is deleted. So the new version updates the interface status and sets ifp->ifindex to IFINDEX_INTERNAL. (ospf6_zebra_route_update) Use if_indextoname properly. * ospf_vty.c: (show_ip_ospf_interface_sub) Show ifindex and interface flags to help with debugging. * ospf_zebra.c: (ospf_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. (zebra_interface_if_lookup) Make function static. Tighten up code. * rip_interface.c: (rip_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL. * ripng_interface.c: (ripng_interface_delete) After deleting, set ifp->ifindex to IFINDEX_INTERNAL.
