| * Two passes on update (ipv4 and ipv6)Stephen Hemminger2008-04-291-3/+13
| | | | | | | | | | | | | | | | When interface comes down, need two passes over the rib to correctly process rib updates. If interface has both ipv6 and ipv4 routes and comes down, need to do it as a two step process. Not sure exactly why, but suspect it has to do with the the work queue and the flagging of activity to the head of the list.
| * Check nexthop statusStephen Hemminger2008-04-281-20/+20
| | | | | | | | | | | | Need to check if next hop is interface and if so then only mark route active is interface is active. This addresses some of the problems with static routes when interface goes down.
| * Check nexthop for internal routesStephen Hemminger2008-04-261-0/+22
| | | | | | | | | | | | Check if nexthop is active when doing RIB update. This should fix issues with static routes staying active after link going down.
| * mark static routes as inactive when link is downStephen Hemminger2008-04-241-2/+23
| | | | | | | | | | | | When link becomes unavailable, unselect any routes that use that link as the next hop. This keeps routing protocols from propogating routes these routes and greating black holes.

| | | | | | | | | | | | | | The filter rules were incorrect (jump to wrong offset), so the kernel would not accept them. Fixes: 2570

Schorr <ajschorr@alumni.princeton.edu> * lib/zebra.h: Revert previous change, no need to include <net/if_media.h> here. * zebra/ioctl.c: If HAVE_BSD_LINK_DETECT is defined, include <net/if_media.h> (if_get_flags) Remove debug messages about BSD link state. * zebra/kernel_socket.c: (bsd_linkdetect_translate) If link state is unknown, we should set the IFF_RUNNING flag.

(ifm_read) Call bsd_linkdetect_translate to fix the IFF_RUNNING flag before calling if_flags_update.

* | Filter unwanted netlink messagesStephen Hemminger2008-03-311-1/+32
| | | | | | | | | | | | Use socket filter to drop unwanted messages on the netlink listen socket. This prevents problems where the listener socket buffer gets overrruns with echos of the new route update that occurs when link changes.

Schorr <ajschorr@alumni.princeton.edu> * zebra_routemap.c: (route_set_src_compile) Use '#ifdef HAVE_IPV6' as needed. * zebra_vty.c: (vty_show_ip_route_detail, vty_show_ip_route) Use '#ifdef HAVE_IPV6' as needed. (show_ip_protocol) Move function definition outside of '#ifdef HAVE_IPV6' section.
* [PtP] Fix BSD problems with PtP interfaces: must treat RTA_BRD as peer addressajs2007-05-172-14/+45
| | | | | | | | | | | 2007-05-17 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * kernel_socket.c: (ifam_read_mesg) Grab RTA_DST and RTA_GATEWAY addresses from the message (if present, which seems unlikely on current BSD platforms), and show them in the debug messages. Also, add ifam_flags to the debug messages. (ifam_read) If the interface is point-to-point, then the RTA_BRD address should be treated as a peer address.
* [autoconf] bugs 162,303,178: Fix 'present but can not be compiled' warningspaul2007-05-108-59/+59
| | | | | | | | | | | | | | | | | | | | | | | | 2007-05-09 Paul Jakma <paul.jakma@sun.com> * configure.ac: sys/conf.h depends on sys/param.h, at least on FBSD 6.2. (bug #363) Should check for in_pktinfo for IRDP 2006-05-27 Paul Jakma <paul.jakma@sun.com> * configure.ac: General cleanup of header and type checks, introducing an internal define, QUAGGA_INCLUDES, to build up a list of stuff to include so as to avoid 'present but cant be compiled' warnings. Misc additional checks of things missing according to autoscan. Add LIBM, for bgpd's use of libm, so as to avoid burdening LIBS, and all the binaries, with libm linkage. Remove the bad practice of using m4 changequote(), just quote the []'s in the case statements properly. This should fix bugs 162, 303 and 178. * */*.{c,h}: Update all HAVE_* to the standard autoconf namespaced HAVE_* defines. I.e. HAVE_SA_LEN -> HAVE_STRUCT_SOCKADDR_SA_LEN, * bgpd/Makefile.am: Add LIBM to bgpd's LDADD, for pow().
