2012-01-02lib: optimize ip_masklen()Denis Ovsienko
The new implementation makes use of a 64KB mapping table, which makes it possible to compute masklen faster and with constant execution time. The map also allows for additional version of the function, which can detect errors in input argument. The previous implementation had a variable cost of execution, which depended on masklen in a non-linear manner, and at its worst (/31) was 4 times slower, than the new implementation. The only case of old function just slightly outperforming the new one is /0, which is of little practical interest.
2012-01-01Revert "lib: optimize apply_mask_ipv6()"Denis Ovsienko
Experience with IPv4 counterpart of this function suggests, that this way of type-punning is likely to cause errors.

2011-12-13lib: clearing zclient.c for some cases of buildingVyacheslav Trushkin
lib/zclient.c: using of HAVE_TCP_ZEBRA in zclient_socket_* definitions extended by else clause.
2011-12-13quagga: option "-z" ("--socket <path>") addedVyacheslav Trushkin
All daemons modified to support custom path to zserv socket. lib: generalize a zclient connection zclient_socket_connect added. zclient_socket and zclient_socket_un were hidden under static expression. "zclient_serv_path_set" modified.

New clause 'match probability <percentage value>' was added in route-maps (bgpd/bgp_routemap.c modified).

2011-12-13ripngd: limit max of "timers basic" to 65535 as documentedUlrich Weber
and use VTY_GET_INTEGER_RANGE instead of calling strtoul
2011-12-13bgp: use VTY_GET_INTEGER_RANGE() in bgp_clear()Ulrich Weber
Second patch replaces "VTY_GET_LONG ("AS", as_ul, arg);" by "VTY_GET_INTEGER_RANGE ("AS", as, arg, 1, BGP_AS4_MAX);" as done in all other code, which parses AS numbers.
2011-12-13ospf6d: implement 'match interface' for route-mapsVyacheslav Trushkin
ospf6_routemap_rule_match_interface* was imported from ospfd daemon with minor changes. new CLI options defined. `ospf6_routemap_rule_match_interface' was changed to support IPv6 (ospfv3) route's external information.

2011-11-21bgpd: fix AS4_PATH attr flag check (BZ#676)Denis Ovsienko
AS_PATH is a well-known, transitive path attribute and cannot be flagged as "Partial". This is what commit 77a20b8af32c926176f8492a086d9e4ec670496b implemented, but it did not account, that bgp_attr_aspath() is also used to process AS4_PATH, which is an optional, transitive path attribute and as such may be flagged as "Partial". This change justfies the test condition.

2011-11-21lib: add sockopt helper for setting IPV6_V6ONLY and use itDavid Lamparter
getaddrinfo returns a list of socket parameters for listening. it will contain both IPv4 and IPv6 listening sockets. unless we use IPV6_V6ONLY on the IPv6 ones, only the socket listed first will work. if the IPv4 one came first, the IPv6 one would get an "Address in use" error. this functionality was already present for bgpd and its listening sockets. as it is needed for vtys as well, make it a common helper.
2011-11-21lib: put route_types.txt to real useDavid Lamparter
this replaces most occurences of routing protocol lists by preprocessor defines from route_types.h. the latter is autogenerated from route_types.txt by a perl script (previously awk). adding a routing protocol now is mostly a matter of changing route_types.txt and log.c. Conflicts: lib/route_types.awk
2011-11-21zebra: fix redistribution of new protocolsDavid Lamparter
redistribute is currently limited to "known" protocols. there is no reason for this limitation, so, remove it.
2011-11-21rib: default distance value for new protocols (v2)David Lamparter
adding protocols and forgetting to update zebra_rib.c currently causes a beyond end of array access for the default distance value. fix by making 150 the default distance for unknown routing protocols. 150 is higher than all other IGPs but lower than iBGP (200)
2011-11-21build: fixup autoconf for cross-compiling (to OpenWRT)David Lamparter
MALLOC/REALLOC aren't used properly (no rpl_malloc), remove them while at it, infer some sane ipforwarding method from the OS value. (v2 on that, "==" is not a proper operator for standard "test")
2011-11-21zebra: set the interface link-layer socket addressTom Goff
* 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().
2011-11-21bgpd: remove unused function bgp_bind_addressDavid Lamparter
bgp_bind_address is replaced with sockunion_bind.
2011-11-21bgpd: fix update-source for IPv6 (BZ#548)David Lamparter
if update-source was given as interface name, bgpd was unconditionally trying to bind to an IPv4 address from that interface. change function to find the best-matching (number of address bits) same-family address on the interface.
2011-11-21lib: prefix2sockunion, prefix_common_bits helper functionsDavid Lamparter
prefix2sockunion converts a struct prefix* to a union sockunion *; prefix_common_bits counts the number of common bits in the prefix's address part.

2011-11-15bgpd: justify capabilities for TOS settingChris Luke
To set the TOS bits on TCP connections, platforms that restrict capabilities need the priv level to be raised before the sockopt is set, and this requires the ZCAP_NET_ADMIN priv. * bgp_main.c: update _caps_p to include ZCAP_NET_ADMIN * bgp_network.c * bgp_connect(): request ZPRIVS_RAISE/ZPRIVS_LOWER * bgp_listener(): request ZPRIVS_RAISE earlier
2011-11-15ospfd: improve fix to CVE-2011-3326 (BZ#586)Thomas Ries
Make ospf_flood() propagate error returned by ospf_lsa_install() further to properly discard the malformed LSA, not just prevent the immediate crash.

Commit 05a4936b713b9882171d0f7fb20b8439df23939e fixed some of the attributes involved, but not all. This commit should do it. * bgp_attr.c * bgp_attr_originator_id() * bgp_attr_cluster_list() * bgp_mp_reach_parse() * bgp_mp_unreach_parse()

2011-10-17ospf6d: make some old sizing checks assertionsDenis Ovsienko
As long as ospf6_packet_examin() is now the single checkpoint for received packets, most of the old checks performed elsewhere can be converted into assert() constructs. Malformed input data at respective points can be attributed solely to a programming error, not a malformed packet. * ospf6_message.c * ospf6_hello_print() * ospf6_dbdesc_print() * ospf6_lsreq_print() * ospf6_lsupdate_print() * ospf6_lsack_print() * ospf6_hello_recv() * ospf6_dbdesc_recv_master() * ospf6_dbdesc_recv_slave() * ospf6_lsreq_recv() * ospf6_lsupdate_recv() * ospf6_lsupdate_recv() * ospf6_lsack_recv() * ospf6_receive()
2011-10-17zebra: trivial warning fixPaul Jakma
* zebra_routemap.c: (route_set_src) get rid of the dummy family variable.
2011-10-17doc: Add dependency for quagga.pdf make targetPaul Jakma
* doc/Makefile.am: pdf target needs to depend on all the input files.
2011-10-17bgpd: improve "monotonic" uptime correctionJohn Kemp
Older versions of Quagga/Zebra would output a value in MRT table dump files for "uptime" aka "ORIGINATED" that was a WALL clock value. Given that uptime is now internally a bgp_clock MONOTONIC value, the output in the MRT files is showing up as monotonic. Note: time of MRT dump is still recorded correctly as a time() based value, so we haven't lost that value. Proposal is to correct the uptime output on the vty and in the MRT files to again display something more akin to WALL time. * bgp_dump.c: (bgp_dump_routes_func) add conditional correction * bgp_route.c: (route_vty_out_detail) make correction conditional, move variable declaration to beginning of the function
