2012-04-07lib: add stream_set_endp()Subbaiah Venkata
* lib/stream.[ch]: - Add stream_set_endp(). This can be used to trim data (for example, padding) at the end of a stream. - Fix swapped 'getp' and 'endp' parameters in STREAM_WARN_OFFSETS. From: Subbaiah Venkata <svenkata@google.com> Signed-off-by: Avneesh Sachdev <avneesh@opensourcerouting.org> Signed-off-by: David Lamparter <equinox@diac24.net>
2012-04-07lib: add support for keyed-hashing with MD5Josh Bailey

2012-04-07lib: Tweaks to linked list macrosJosh Bailey
* lib/linklist.h - Change the listnextnode, listhead and listtail macros so that they allow the list pointer to be NULL. - Modify the ALL_LIST_ELEMENTS* macros such that they clear the data pointer at the beginning and end of the loop.

2012-04-04lib: pretty ip_masklen and masklen2ipDavid Lamparter
nonwithstanding any desire for optimisation, these versions are shorter and more concise. reading the comments, they might even be easier to understand. I've tested them on i686 and x86_64, and checked that correct assembler code is emitted for ARM, MIPS and PowerPC. IPv6 is left as an exercise for another day, none of the ideas I had led to a "yes, this is the one to go with" solution. Signed-off-by: David Lamparter <equinox@diac24.net>
2012-04-04Revert "lib: optimize ip_masklen()" (BZ#720)David Lamparter
This reverts commit d171bf58ef12ace43d48565e6870722dece1e6ed. There are multiple reasons for this revert, including bug #720, but also quite simply the unreadability of having 2000 lines of an autogenerated table in the middle of a source file.

2012-03-23lib: fix endianness bug in prefix.cRenato Westphal
While defining two "maskbytes" arrays for the respective endiannesses, the code was unconditionally using one that only worked on little endian systems. Use preprocessor macros to avoid the somewhat expensive htonl/ntohl macros. From: Renato Westphal <renatowestphal@gmail.com> Signed-off-by: David Lamparter <equinox@diac24.net>
2012-02-28lib: fix incorrect thread list processing loopsPaul Jakma
* thread.c: (thread_timer_process,thread_process) thread_list_delete nulls thread->next. Loops need to save next first, or will only process the head. Problem noted by Lou Berger <lberger@labn.net>.

2012-01-06lib/if: trivial, fix rarely used if debug function to print everythingPaul Jakma
* if.c: (if_dump) loop that doesn't do anything, wants to be before the zlog of what it's meant to print out so all the connected addresses get printed out. Trival: just a debug function
2012-01-06general: remove inline qualifiers and move in-header functions to objectsPaul Jakma
* (general) Move functions in headers into files, to be compiled into shared object files. Remove inline qualifier from functions. Let the compiler do the work.

2012-01-02lib: address type-punned pointers in prefix_same()Denis Ovsienko
IPV4_ADDR_SAME() wasn't passed the right union member, this could cause a bug due to strict-aliasing. IPV6_ADDR_SAME() case got its fix before the error could be created by macro upgrade.

2012-01-02zebra: ZEBRA_HELLO and mopping up routes (BZ#448)Vyacheslav Trushkin
ZEBRA_HELLO message is used by routing daemons to inform zebra what type of routes daemon will be announcing to zebra. Also zebra uses route_type_oaths array to track which daemon announces which protocol. Zebra mops up routes if daemon didn't for some reason.
2012-01-02lib: fix type-punning in ip_masklen()Denis Ovsienko
ip_masklen() was likely to return incorrect results after being compiled with -fstrict-aliasing (-O2, -O3, -Os)
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: 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. Conflicts: lib/sockunion.c
2011-12-13lib: 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

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.
2011-12-07lib: fix SMUX compiler warningsStephen Hemminger
Make progname a string, and cast when calling asn1. Remove variable set but never used.
2011-12-07lib: fix compile warnings from set-never-usedStephen Hemminger
The if_dump code had empty loop, that caused set-never-used warning.
2011-12-07vty_serv_sock_family unusedStephen Hemminger
If the vty_serv_sock_addrinfo is being used, then vty_serv_sock_family is unsed. Fix by adjusting ifdef/else/endif
2011-12-06lib: fix memory leak on connect() failureStephen Hemminger
Change sockunion_log() to not use strdup(). This fixes a small memory leak that occurs on every failed connect(), and is simpler/cleaner.
2011-12-06lib: call filter delete hook before freeing access listStephen Hemminger
The delete_hook was being run after calling access list delete function. This would cause ospf to dereference a NULL, in ospf_filter_update because 'access->name' was already freed. See also: https://bugzilla.vyatta.com/show_bug.cgi?id=7654
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.
2011-10-17lib: compile even without IPV6_TCLASSDenis Ovsienko
2011-10-17IPv6 transport class suppportStephen Hemminger
IPv6 supports the same concept of differentiated service for routing protocols as IPv4, but like too many things, the standards committee decided that having two names for the same thing wasn't good enough and introduced a third more generic term transport class. The socket option to set transport class works the same as IPv4, but the arguments are different. * lib/sockopt.[ch] * setsockopt_ipv6_tclass(): new function * bgpd/bgp_network.c * bgp_connect(): set socket option * bgp_listener(): set socket option * ospf6d/ospf6_network.c * ospf6_set_transport_class(): new function * ospf6_serv_sock(): set socket option * ripngd/ripngd.c * ripng_make_socket(): set socket option

2011-09-29bgpd: rename SAFI 3 according to RFC4760Denis Ovsienko
- SAFI value 3 is reserved. It was assigned by RFC 2858 for a use that was never fully implemented, so it is deprecated by this document. * zebra.h: rename macro * bgp_fsm.c: (bgp_graceful_restart_timer_expire, bgp_graceful_stale_timer_expire, bgp_stop, bgp_establish): update * bgpd.c: (peer_nsf_stop): update * bgp_open.c: (bgp_capability_vty_out): SAFI 3 isn't a recognized case any more
2011-09-27lib: provide more information in case of failed LOOKUP.Dmitrij Tejblum
* log.[ch] * mes_lookup: add a parameter with the name of the message list, print the name in case of failure. * LOOKUP macro: pass the name of the message list.
2011-09-27lib: use "protocol-independed API" from RFC3678, if that is availableDmitrij Tejblum
(This commit is based on the patch from BZ#420, and should fix that bug.) * configure.ac: detect availability of that API * sockopt.c (setsockopt_ipv4_multicast): use it for join/leave IPv4 multicast groups
2011-09-27lib: futher simplification of setsockopt_ipv4_multicast()Dmitrij Tejblum
* sockopt.c (setsockopt_ipv4_multicast): check for wrong optname with assert(), rather than return an error.
