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>

| * | | | lib: Do better filtering of arguments, optional args particularlyPaul Jakma2010-02-031-181/+144

(cmd_match) Consolidate matching code from cmd_filter_by_* to here. Use cmd_deopt to match on the /inner/ argument of an optional string, rather than treating optional arguments as matching pretty much any string. (cmd_filter) consolidate cmd_filter_by_* to here, and use cmd_match. Further, do a two-pass filter, to make use of the fact that we know the "strongest" match (e.g. range-match args beat variables) and can filter out weaker ones. Along with ability to match on inside of optional arguments, this makes our command definitions more powerful, and should allow us to avoid much redundancy in command defs. (is_cmd_ambiguous) look inside optional args, for better matching.
| * | | | bgpd: New show commands for improved view and address family supportMichael Lambert2010-02-032-15/+991

The following changes add a number of commands with support for views and rationalized treatment of IPv4 v IPv6 and unicast v multicast (such as in JUNOS, IOS XR and more recent versions of IOS). * bgp_route.c: (bgp_show_community) Inserted a new second argument (the name of the view) and the code to look up that name in the BGP structure. The NULL argument in the call to bgp_show (indicating the default view) was replaced by the specified view. The existing calls to bgp_show_community had a NULL second argument inserted to make clear that they refer to the default view. (top level) Added new functions via the DEFUN and/or ALIAS macros (and the associated command table entries) to add the commands show bgp ipv4 (unicast|multicast) show bgp ipv4 (unicast|multicast) A.B.C.D show bgp ipv4 (unicast|multicast) A.B.C.D/M show bgp ipv6 (unicast|multicast) show bgp ipv6 (unicast|multicast) X:X::X:X show bgp ipv6 (unicast|multicast) X:X::X:X/M These show either the full BGP table or the specified route or prefix for the given address family. show bgp view WORD (ipv4|ipv6) (unicast|multicast) community show bgp view WORD (ipv4|ipv6) (unicast|multicast) community \ (AA:NN|local-AS|no-advertise|no-export){1,4} For the specified view and address family, these show entries matching any community or the specified communit(y)(ies). show bgp view WORD (ipv4|ipv6) (unicast|multicast) neighbors \ (A.B.C.D|X:X::X:X) (advertised-routes|received-routes) For the specified view and address family, show the routes advertised to or received from the given BGP neighbor. show bgp [view WORD] ipv4 (unicast|multicast) \ rsclient (A.B.C.D|X:X::X:X) show bgp [view WORD] ipv4 (unicast|multicast) \ rsclient (A.B.C.D|X:X::X:X) A.B.C.D show bgp [view WORD] ipv4 (unicast|multicast) \ rsclient (A.B.C.D|X:X::X:X) A.B.C.D/M show bgp [view WORD] ipv6 (unicast|multicast) \ rsclient (A.B.C.D|X:X::X:X) show bgp [view WORD] ipv6 (unicast|multicast) \ rsclient (A.B.C.D|X:X::X:X) X:X::X:X show bgp [view WORD] ipv6 (unicast|multicast) \ rsclient (A.B.C.D|X:X::X:X) X:X::X:X/M For the specifed (optional) view and address family, show either the full BGP table or the specified route or prefix for the given route server client peer. * bgp_vty.c: (top level) Added new functions via the DEFUN and/or ALIAS macros (and the associated command table entries) to add the commands show bgp [view WORD] (ipv4|ipv6) (unicast|multicast) summary show bgp [view WORD] (ipv4|ipv6) (unicast|multicast) rsclient summary For the specified (optional) view and address family, display either the normal summary table for BGP peers, or the route server client table showing the import and export policies.
| * | | | zebra: set the interface link-layer socket addressTom Goff2010-02-031-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * kernel_socket.c: (ifm_read) The reorganization from commit 6fe70d1b35c189cb1e488b2c26551ba7baac6148 removed setting the interface link-layer socket address structure on routing socket platforms. This restores saving the link-layer information because it might be used elsewhere: rtm_write() when no gateway is given, if_dump_vty() and rtadv_send_packet().
| * | | | ospf6d: Fix crash when '[no] ipv6 ospf6 advertise prefix-list' is in ↵David Ward2010-02-031-10/+18

Now, when the command above is issued (either in the startup configuration or at runtime), ospf6d will only schedule LSAs if the 'oi->area' structure has been initalized. A similar test is already used when handling the commands 'ipv6 ospf6 priority' and 'ipv6 ospf6 cost'.

| * | | | BGP: enable TCP corkingStephen Hemminger2010-02-033-11/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On BGP write, use TCP_CORK to provide hints to kernel about TCP buffering. This will cause BGP packets to occur in bigger chunks (full size MTU), improving performance and getting rid of one of the problems reported in the UNH BGP conformance test.
| * | | | BGP: fix crash when allowas-in is doneStephen Hemminger2010-02-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes BGP crash when allow-as is changed on inactive peer. It supersedes Michael Larson's earlier patch. When allowas-in is changed on a peer that is not up, BGP would crash trying to do route_refresh. If peer is not up, there is no need to do notification or send.
| * | | | BGP: only use write event for non-blocking connectStephen Hemminger2010-02-032-16/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to Steven's and other unix network programming books, only write select is needed when doing non-blocking connect. Doing this simplifies the receive path, it also gets rid of some possible races when when a TCP simultaneous connect happens.
| * | | | BGP: leave peer socket in non-blocking mode (mostly)Stephen Hemminger2010-02-032-21/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than toggling socket in/out of non-block mode, just leave it in nonblocking mode. Also, only handle non-blocking and errno's correctly. On write errno is only set if return is less than zero; otherwise errno is from last failed system call. On read errno is only set if return is less than zero. Use convient ERRNO_IO_RETRY() macro to check for AGAIN/INTR etc. One exception is in bgp_notify which only happens just before close.

According to documentation it is only meaningful for out of band data, and no routing protocol uses out of band data. It saves some small amount of kernel overhead to not use it.

| * | | | isisd: fixes 6/7: wrong next-hops from SPFPeter Szilagyi2010-02-033-29/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The forwarding table was filled with wrong next-hops, and which is even worse, it was done in a totally non-deterministic way. The next-hop set for an IP prefix by isisd was the neighbor IS from which the flooded LSP about the IP prefix was arrived. So, if an IS received all the LSPs through its, say, eth0 interface, all entries in the forwarding table contained the next IS reachable via eth0 as the next-hop. The solution is to propagate the correct next-hop further from node to node as the SPF algorithm traverses the graph and selects the next node to be added to the set of already covered nodes. Also, the construction of the tentative node list (the nodes where the shortest path is not known yet) was buggy: if a node was already a member of this list with a certain path cost, and an alternative path was found to it with a lower cost while processing a pseudo-node LSP, it was not added to the list. This way, the path selected by isisd for a certain prefix was the first one it encountered during the LSDB processing. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
| * | | | isisd: fixes 5/7: send proper LSP after DIS electionPeter Szilagyi2010-02-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After an IS has been elected as the Designated IS for a LAN, it did not refresh the content of the pseudo-node after a new node has been connected to the same LAN. Instead, the periodically reoriginated pseudo-node LSP still contained only those IS neighbors that were already present when the DIS election process was commenced. The fix for the problem schedules an LSP regeneration rather than just reoriginating the same LSP with the old content. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
| * | | | isisd: fixes 4/7: circuit state machinePeter Szilagyi2010-02-035-64/+79

When an interface was brought down by a link failure, the interface information was deleted and set to NULL. When the link was restored later, the interface was looked up by the old pointer, but since it was cleared, it was never found again, resulting in an interface never entering the up state again. Also, the program regularly crashed because of a deleted pointer in the same context which was later accessed without any further checking. Signed-off-by: Fritz Reichmann <fritz@reichmann.nl>
