When a BGP session with ADD_PATH is restarted and the neighbor do not
announce ADD_PATH capability during reconnect, the accept_ra_types is
still set to RA_ANY.
Thanks to Lennert Buytenhek for the bugreport
During reconfiguration, old and new filter expressions in static routes
are compared using i_same() function. When filter expressions contain
function calls, it is necessary that old filter expressions are the
second argument in i_same(), as it is internally modified by i_same().
Otherwise pointers to old (and freed) data appear in the config
structure.
Thanks to Lennert Buytenhek for tracking and reporting the bug.
FreeBSD 11 changed endianity of ip_len field from host order to network
order. Also DragonFly BSD allegedly expects network order here.
Thanks to Olivier Cochard-Labbé for the patch.
The variable nfa is not cleaned before each loop iteration and can have
a wrong value of nfa.nhs_reuse from the previous step.
Thanks to Bernardo Figueiredo for the bugreport and analysis.
Stubnet nodes in OSPF FIB were removed during rt_sync(), but the pointer
remained in top_hash_entry.nf, so net-summary LSA origination was
confused, reported 'LSA ID collision' and net-summary LSAs were not
originated properly.
Thanks to Naveen Chowdary Yerramneni for bugreport and analysis.
Prefix and bucket tables are initialized when entering established state
but not explicitly freed when leaving it (that is handled by protocol
restart). With graceful restart, BGP may enter and leave established
state multiple times without hard protocol restart causing memory leak.
Commit 3c09af41... changed behavior of int_set_add() from prepend to
append, which makes more sense for community list, but prepend must be
used for cluster list. Add int_set_prepend() and use it in cluster list
handling code.
Implement BFD authentication (part of RFC 5880). Supports plaintext
passwords and cryptographic MD5 / SHA-1 authentication.
Based on former commit from Pavel Tvrdik
BIRD passed string from configuration to openlog(), which kept it
internally. After reconfiguration the old string was freed, therefore
openlog had invalid copy.
Thanks to Chris Caputo for the original patch.
This commit should fix warning `make docs'
./sgml2html bird.sgml Unescaped left brace in regex is deprecated,

We set buffer->pos to buffer->end in function buffer_print() when
bvsnprintf() failed, so there would be uninitialized memory between
the old buffer->pos and the current buffer->pos.
Add support for large communities (draft-ietf-idr-large-community),
96bit alternative to RFC 1997 communities.
Thanks to Matt Griswold for the original patch.
