* zebra: fix infinite loop when deleting an interfaceRoman Hoog Antink2011-01-191-0/+4
| | | | | | | | | | | | When deleting a VLAN interface after flushing its addresses, zebra uses 100% CPU time and freezes. * interface.c: The while loop in line 407 that should clean up connected routes never hits one of the 2 lines "last = node;" and thus loops forever.

* zebra: fix interface deletion bug introduced by ptp address supportDavid Lamparter2010-03-271-7/+7
| | | | | | | | | meh. forgot to even look at the interface deletion path. this doesn't really work well when looking for the local address in the subnet list which has the connected prefix in it... loop ensues. fix by using the connected prefix when looking at the list of connected prefixes. duh.
* zebra: labels, scopes and preference are IPv4 onlyquagga_1.1.0-dn42.11-rc1David Lamparter2010-02-201-6/+11
| | | | | | | avoid writing out configurations that we can't read back; in particular, the scope field does get set for IPv6 addresses received from netlink and would be written out for "ipv6 address" lines - but it can't actually be configured.

| * lib: get rid of extraneous output with vty_prependDavid Lamparter2010-02-052-3/+10
| | | | | | | | | | | | | | | | | | the vty_*prepend* family can be used to reduce the amount of output produced by "show running-config" and "write ...". it buffers output in struct vty->prepend (1024 bytes) and outputs it when vty_out is called. if vty_out isn't called, it can be removed with vty_unprepend later. applied on zebra and ospfd to get rid of empty interface blocks.

| * | zebra: rib: support blackhole kernel deletion notificationDavid Lamparter2010-02-051-0/+12

| * | zebra: consider all nexthops when looking for a gateway matchTom Goff2010-02-051-10/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * zebra_rib.c: (rib_delete_ipv4 and rib_delete_ipv6) A route is not deleted unless the given gateway is first in the nexthop list. This can leave a route containing an invalid nexthop in the routing table which might later be used. Instead look at all nexthops to find a match. forward-ported to apply on top of Joakim Tjernlund's "don't delete too many routes" by David Lamparter.

| * | zebra: Don't delete too many routes.Joakim Tjernlund2010-02-051-30/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there are two paralell PtP links to the same router: C * 192.168.101.112/32 is directly connected, p1-4-19-4-20 C>* 192.168.101.112/32 is directly connected, p1-4-17-4-18 and the cable is to one of the ppp links is pulled, Zebra deletes both routes instead of just the one that got yanked. This fixes it to only delete the route to the interface that got yanked. In fact, the whole delete route pattern matching expressions needed a total makeover.
| * | zebra: netlink: grab blackhole list from kernelDavid Lamparter2010-02-052-11/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | support processing of RTM_BLACKHOLE et al. from kernel and dump them into appropriate blackhole rib entries. this exhibits the deletion bug famously fixed by Joakim Tjernlund, if that patch isn't applied blackhole route deletion from kernel doesn't work...
| * | zebra: cleanup blackhole supportDavid Lamparter2010-02-057-310/+239
| | | | | | | | | | | | | | | | | | | | | | | | blackhole support was horribly broken. cleanup by removing blackhole stuff from ZEBRA_FLAG_*, instead add a "zflags" field inside struct rib. introduces support for "prohibit" routes (Linux/netlink only) also clean up blackhole options on "ip route" vty commands.

| * | | zebra: rib update in background and recursive routesStephen Hemminger2010-02-054-11/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now Zebra doesn't support recursive routes correctly when the next hop is a dynamic protocol. Imagine the case where a static route was entered to destination X.X.X.X via Y.Y.Y.Y and a protocol created a route to Y.Y.Y.Y. Any change from that protocol to Y.Y.Y.Y would might require zebra to update it's recursive route. The RIB as is doesn't have the necessary state to do this quickly, and the rib_update() and the resulting meta-queue is slow (2N) with lots of routes. That combined with the incremental updates from protocols makes the whole process potentially N^2. When we enabled it for BGP, the feed to 30min to complete. The comprimise I took was to start a delayed thread when zebra receives an update from protocol. So only a limited number of scans are done. I know this conflicts with your cleanup; but this might provide additional help. The existing meta-queue stuff makes the rib update worse not better.

This simple combines the IPv6 stateless address auto-configuration process with the ability to get DNS server information - in one message. This options frees many environments from operating an additional DHCPv6 server that provides such information. This patch extends quagga by the ability to generate and transport RDNS addresses. RDNSS options are currently supported at radvd(1) and the Linux Kernel by handover this information to the user-space (via netlink socket). A simple RA configuration with two RDNS entries can be enabled via no ipv6 nd suppress-ra ipv6 nd prefix 2001:db8::/64 ipv6 nd rdnss 2001:db8::1 ipv6 nd rdnss 2001:db8::2 It is additionally possible to specify the lifetime of an RDNSS option as stated in [1] section 4.1. The default is infinity lifetime (0xfffffff) as it serves the most common application areas. ip nd rdnss 2001:db8::1 300000 [1] http://tools.ietf.org/html/rfc5006 Signed-off-by: Hagen Paul Pfeifer <hagen@jauu.net>

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | * kernel_socket.c: (ifm_read) The reorganization from commit 6fe70d1b35c189cb1e488b2c26551ba7baac6148 removed setting the interface link-layer socket address structure on routing socket platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | zebra address bookkeeping is a mess. this is just a workaround to have IPv4 address deletion somewhat working on Linux. the if_unset_prefix call is synchronous, when it returns success the address deletion completed successfully. this is either signaled by a netlink ACK or by an OK return value from ioctl().

* | zebra: change router-id selection algoStephen Hemminger2009-12-211-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The router-id table looks like is supposed to be sorted in current quagga code, but the nodes are not added with the sorting function. The sorting function is host byte order dependent. The values need to converted before comparison. Fixing this causes Zebra to choose the largest IP address as router-id, rather than the last address. This probably will surprise some users. The other option would be to just remove the comparison function and keep the existing LIFO behavior. Lastly, simple subtraction works well for comparing. * zebra/router-id.c * router_id_add_address(): employ listnode_add_sort() * router_id_cmp(): employ ntohl(), then compare integers
