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
* lib/md5.[ch] Add implementation of HMAC-MD5 from RFC 2104. From: Josh Bailey <joshb@google.com> Signed-off-by: Avneesh Sachdev <avneesh@opensourcerouting.org> Signed-off-by: David Lamparter <equinox@diac24.net>
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.

2012-03-27bgpd: bgp_attr_flags_diagnose shouldn't assertPaul Jakma
* bgpd/bgp_attr.c: (bgp_attr_flags_diagnose) debug code for error-handling paths probably shouldn't assert, instead it should just log that there was no problem.
2012-03-27bgpd: attr_parse call to attr_malformed should deal with PROCEED error casePaul Jakma
* bgpd/bgp_attr.c: (bgp_attr_parse) the invalid flag check call to bgp_attr_malformed is pretty useless if it doesn't actually allow for the PROCEED non-error case.
2012-03-27bgpd: Fix silly mistake in bgp_attr_flag_invalidPaul Jakma
* bgp_attr.c: (bgp_attr_flag_invalid) flags is meant to be masked off with the mask variable...
2012-03-25bgpd: malformed attribute error that can still proceed should fixup getpPaul Jakma
* bgp_attr.c: (bgp_attr_malformed) When a malformed attribute error can be ignored, and BGP message processing may still proceed, the stream getp should be adjusted to the end of the attribute - the caller may not have consumed all the attribute. Problem noted by Martin Winter in bug 678. Also, rename the 'startp' local to 'notify_datap', for clarity.

2012-03-25babeld: remove "parasitic" mode.Juliusz Chroboczek
This is the functionality described in Appendix C of RFC 6126. Its main purpose is to avoid keeping a full source table, which makes it possible to implement a subset of Babel in just a few hundred lines of code. However, in Quagga the code for maintaining the source table is already there, and a parasitic implementation can be simulated using filtering -- so it makes little sense to keep the functionality.
2012-03-25babeld: 3 more timing statements in config textDenis Ovsienko
This commit makes the following lines visible in running-config text, when respective intervals are configured to non-default values: * babel hello-interval * babel update-interval * babel resend-delay

2012-03-25babeld: remove remains of standalone babeld's configuration code.Juliusz Chroboczek
Standalone babeld has a configuration interface that is not used in Quagga. This removes a few bits of this code that survived the port to Quagga.
2012-03-25babeld: drive interface_config_write() forwardDenis Ovsienko
2012-03-25babeld: justify "running-config" meaning in CLIDenis Ovsienko
The primary focus of this commit is to make "show running-config" command display more current configuration, including some of the bits previously seen in the output of "show babel running-config". Besides that, the following commands were renamed for consistency with the syntax of other components: "debug *" to "debug babel *" (and moved to top level) "show babel running-config" to "show babel parameters" * babel_interface.c * show_babel_running_config(): rename to show_babel_parameters(), update syntax pattern, don't call show_babeld_configuration() * babel_if_init(): update respectively * babel_enable_if_config_write(): new VTY helper for static babel_enable_if * babel_interface.h: add extern declaration * babel_main.c: unset all debug options by default * show_babel_main_configuration(): remove debug options decoder * babel_zebra.c * babel_debug(): rename to debug_babel(), update syntax pattern * no_babel_debug(): rename to no_debug_babel(), update syntax pattern * babelz_zebra_init(): update respectively * debug_babel_config_write() new VTY helper for static debug_type * babel_zebra.h: add extern declaration * babeld.c * babel_config_write(): add the code to output "debug babel *", "router babel", "redistribute *" and "network *" statements * show_babeld_configuration(): dismiss * babeld.h: remove extern declaration * babeld.texi: update for renamed commands * babeld.conf.sample: idem, add debug statements block

They didn't work anyway, since they're called too late.
2012-03-25Resynchronise with babeld-1.3.1.Juliusz Chroboczek
2012-03-25babeld: dismiss babel_redistribute_unset()Denis Ovsienko
The function was effectively duplicating existing zclient_redistribute(). This makes no_babel_redistribute_type() consistent with babel_redistribute_type()

2012-03-25babeld: Add support for blackhole routes.Juliusz Chroboczek
Babel makes use of blackhole routes to prevent routing loops between overlapping prefixes shortly after a route is retracted (see RFC 6126 sections 2.8 and 3.5.5). This patch adds support for installing such blackhole routes.
2012-03-25babeld: refactor filtering stubs.Juliusz Chroboczek
Factorise the common parts of the in/out filtering functions. This also fixes a bug with filtered out routes, which in babeld are signalled by a filter returing INFINITY, not -1.
2012-03-25zebra: Display uptime of Babel routes in show ip[v6] route.Juliusz Chroboczek
2012-03-25babeld: Use quagga_gettime.Juliusz Chroboczek
2012-03-25babeld: Don't use an ifindex when installing IPv4 routes.Juliusz Chroboczek
Stand-alone babeld installs routes using both a next-hop gateway and an interface index. Unfortunately, this doesn't work for IPv4 under Quagga. We now ignore the ifindex when installing IPv4 routes, which makes Babel work for IPv4 in prefix-based networks. Of course this breaks IPv4 mesh networks, unless you play some tricks with your interfaces' netmasks.

2012-03-25babeld: fix interface bug, simplify code.Matthieu Boutier
Perhaps could it be able to free already free memory (so free(NULL)), in function interface_reset(). On other hand, it initiated untracked interfaces, raising (at least) inappropriate messages. Finally, I remove the BABEL_IF_IS_ENABLE flag, witch was not really usefull. Note the test if_up isn't weaker, because (...IS_UP => ...IS_ENABLE).
2012-03-25babeld: state-file was loaded too early. Initial seqno too.Matthieu Boutier
