2012-05-22bgpd: optimize aspath string representation and assegments handlingJorge Boncompte [DTI2]
* bgp_aspath.h: Add str_len to struct aspath. * bgp_aspath.c: Save the aspath string representation length and use it instead of strlen(). (aspath_make_str_count) assign the string buffer directly for consistency with the string length and change the return type to void. (aspath_dup) use str_len and copy the string instead of calling aspath_make_str_count(). (assegment_data_new) change from XCALLOC to XMALLOC. All users initialize the memory before use. (assegment_data_free) unused, removed. (aspath_intern) check that there's always a ->str pointer. (aspath_hash_alloc) reuse assegments and string representation instead of copying them. (aspath_parse) now aspath_hash_alloc does not dupes memory, free the temporary structures only if the aspath it is in the hash. (aspath_cmp_left) remove useless NULL initialization.

2012-05-21bgpd: fix crash with vpnv4 soft-reconfigurationJorge Boncompte [DTI2]
bgp_afi_node_get() expects a non-NULL prd for a SAFI_MPLS_VPN prefix. * bgp_route.c: pass down the struct prefix_rd from bgp_soft_reconfig_in() and bgp_soft_reconfig_rsclient(). Signed-off-by: Jorge Boncompte [DTI2] <jorge@dti2.net> Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-05-21lib: fix thread_cancel_event()Jorge Boncompte [DTI2]
ospfd was crashing some times on neighbour going down. The cause was that ospf_nsm_event() was accessing already freed memory in ospf_nbr_delete() call from ospf_nsm_event(). What happens is that since commit b5043aab (lib: fix incorrect thread list...) now a thread can be on the event and ready lists but thread_cancel_event() doesn't account for that. * thread.c: (thread_cancel_event) loop on the ready list too to cancel pending events.

2012-05-21lib: drop heuristic IPv6 address recognitionRoman Hoog Antink
* command.c: (cmd_ipv6_match) Drop IPv6 address recognition heuristics and solely rely on inet_pton, because strings like "abcd" were mistaken for IPv6 addresses. This affects e.g. the command "neighbour WORD peer-group", which won't work with words consisting of up to 4 characters between 'a' and 'f' and digits.

2012-05-09zebra: fix up compilation without rtadv/IPv6Joachim Nilsson
let's ground the rtadv.h file if route advertisements are disabled. And fix up the CLI for it, as well as move the "show ip mroute" to its proper place. * zebra/rtadv.h: #ifdef RTADV * zebra/main.c: #ifdef RTADV * zebra/zebra_vty.c: move "show ip mroute" out of #ifdef IPV6 From: Joachim Nilsson <troglobit@gmail.com> [moved #ifdef RTADV to rtadv.h] Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
2012-05-02zebra: feed Connected routes into MRIBG.Balaji
The SAFI_MULTICAST RIB needs to contain Connected routes so that the nexthop lookup does not fail and so that multicast routing daemons do not need to sidestep and look into SAFI_UNICAST to be aware of connected subnets. * zebra/connected.c: add & delete connected in SAFI_MULTICAST Signed-off-by: G.Balaji <balajig81@gmail.com> [merged add/delete patches] Signed-off-by: David Lamparter <equinox@diac24.net>
2012-05-02zebra: no need to clear memory of the netlink buffersJorge Boncompte [DTI2]
The memory is always written before sending. Clearing it before use slows netlink_route_multipath() down considerably and it's pretty noticeable in a full-internet table scenario loading. * zebra/rt_netlink.c: subtract bulk buffer size from clear Signed-off-by: Jorge Boncompte [DTI2] <jorge@dti2.net> [reworded commit message] Signed-off-by: David Lamparter <equinox@diac24.net>

2012-05-02bgpd: Fix memory leak of some "show ip bgp neighbor" commandsJorge Boncompte [DTI2]
sockunion_str2su() use is prone to memory leaks. Remove it's use all over the code. At least these commands leaked a sockunion union: - show ip bgp vpnv4 ... routes - show ip bgp ... received prefix-filter Signed-off-by: Jorge Boncompte [DTI2] <jorge@dti2.net> Signed-off-by: David Lamparter <equinox@diac24.net>

2012-05-02bgpd: Fix regression in args consolidation, total should be inited from argsPaul Jakma
* bgp_attr.c: (bgp_attr_unknown) total should be initialised from the args.
2012-05-02bgpd: Make socket init separate, so unit tests work again.Paul Jakma
* Separate out BGP socket initialisation from bgp_get, and make it an explicit function. Allows unit tests to work again and probably also benefits dry-run. * bgpd.c: (bgp_get) move socket init out... (bgp_socket_init) to here * bgp_main.c: and call it after dry-run. * bgpd.h: (bgp_socket_init) add prototype

2012-04-28bgpd: fix up multipath merge breakageDavid Lamparter
the BGP multipath code was developed against a pre-f6f434b Quagga where bgp_attr_unintern and ecommunity_free took single-star pointers. They now take double-star pointers. * bgpd/bgp_mpath.c: fix up bgp_attr_unintern & ecommunity_free calls. Signed-off-by: David Lamparter <equinox@diac24.net>
2012-04-28babeld: merge kernel_zebra.c into kernel.c.Juliusz Chroboczek
In upstream babel, we include different kernel_foo files depending on the platform we compile for. In Quagga, this is not needed, and it avoids tricky autotools issues.

2012-04-20lib: bump ZSERV_VERSION to 2David Lamparter
continually changing the zserv protocol without bumping up the version number has made it impossible to talk to zebra without knowing the exact version. in reality, increasing the version number more often guards against inadvertedly running incompatible versions of a daemon and zebra as well as aids external development. * lib/zclient.h: #define ZSERV_VERSION 2 Signed-off-by: David Lamparter <equinox@diac24.net>
2012-04-20Revert "zebra: clean up client routes when client goes away"David Lamparter
This reverts commit af56d404cd56d94ad3b2ec3f159650eb72baef0a, which was accidentally duplicating functionality from commit 2ea1ab1 "zebra: ZEBRA_HELLO and mopping up routes (BZ#448)" Conflicts: zebra/zebra_rib.c Signed-off-by: David Lamparter <equinox@diac24.net>
2012-04-16bgpd: Fix crash when disabling dampening (BZ#687)Jorge Boncompte [DTI2]
Vladimir Podobaev reported that the following commands crashed the daemon. router bgp 123 bgp dampening no bgp dampening 1 2 3 4 no bgp dampening The problem was that bgp_damp_info_clean() tried to dereference the already freed reuse_list array in the second call to "no bgp dampening". Fixed by checking in bgp_damp_disable() that the dampening it's enabled before doing the cleanup. Signed-off-by: Jorge Boncompte [DTI2] <jorge@dti2.net>

2012-04-16zebra: use larger buffer (4096) for netlink messagesJR Rivers
Increase the maximum number of nexthops per route by using a larger buffer for netlink messages. * zebra/rt_netlink.c: Use a buffer of 4096 bytes to parse/build netlink messages. Add a hash define for this number (NL_PKT_BUF_SIZE). Most places in the code were previously using a buffer of 1024 bytes.
2012-04-16isisd: merge osr/google-is-isDavid Lamparter
this is essentially half of a rewrite of isisd. please note that a lot of things are still broken and isisd is not ready for production use.
2012-04-16quagga: option "-z" ("--socket <path>") addedVyacheslav Trushkin
All daemons modified to support custom path to zserv socket. [reapplied from b511468 after isisd merge]

2012-04-16bgpd: merge osr/quagga-osr-patches (BZ#700)David Lamparter
this merges a bgp capability negotiation fix where bgpd would fail if no multiprotocol capability was present, but other capabilities were.
2012-04-16bgpd: merge osr/google-bgp-multipathDavid Lamparter
this patchset allows collapsing multiple received routes in BGP into one multipath route that will, if readvertised, contain an aggregate of all received attributes.
2012-04-11isisd: reapply patch to fix zebra protocolAvneesh Sachdev
Reapply the bits of revision b4e45f6 that pertain to isisd. That is: git log -n 1 -p b4e45f6 -- isisd These were dropped in the merge with the Google ISIS code (14d2bbaa). The commit message for b4e45f6 is: fix zebra protocol after MP-BGP changes The previous commits modified both zebra and bgpd for additional SAFI field, but not any other routing daemon, which led to zebra daemon crashing with failed assertion.

Conflicts: bgpd/bgp_route.c
2012-04-08bgpd: fix issue in capability negotiation (BZ#700)Avneesh Sachdev
Address problem where bgpd would reject a session if a peer sent some capabilities in its Open message, but did not include a Multiprotocol extensions capability. Note that the session would come up if there were no capabilities at all in the Open message. * Add the 'mp_capability' out parameter to bgp_capability_parse(). Set it to '1' if a Multiprotocol extensions capability is encountered. * Switch on 'mp_capability' instead of 'capability' in the calling functions to determine if the peer indicated the set of AFI/SAFIs it supports. The net result is that when a peer does not send an MP capability, it is assumed to support the AFI/SAFIs configured for it locally.
2012-04-08zebra: include hardware addr in if up/down messagesJosh Bailey
Change interface up/down notification messages to also include the hardware address of the interface. The format of these messages is now identical to the interface add message -- move the serialization code to common functions. * lib/zclient.c: Modify zebra_interface_if_set_value() to also parse the hardware address. Invoke it from zebra_interface_add_read() and and zebra_interface_state_read(). * zebra/zserv.c: Add zserv_encode_interface(). Invoke it from zserv_interface_add(), zserv_interface_delete() and zserv_interface_update().
2012-04-08lib: Tweak to if_delete_retain()Josh Bailey
* lib/if.c: Change if_delete_retain() to delete all connected addresses, but to not free the list that holds them. Free the list just before the interface structure itself is freed, in if_delete().
2012-04-08zebra: clean up client routes when client goes awayJosh Bailey
* zebra/zebra_rib.c: Add code to clean up routes added by a client (as identfied by 'rib type'). * zebra/zserv.[ch]: Maintain the type of the routes added by a client on the 'zserv' structure -- assume that a given client uses a single route type for now.
