1757a6fce5 Filter: Stacks moved to thread-local storage if available. 2019-05-29 21:03:52 +02:00

6479e403ef Filters: If somebody doesn't like _Thread_local, don't fail for now, just be a little slower.
When the parallel execution comes into place, we'll likely enforce this
C11 feature. It's much simpler and also faster than pthread_[sg]etspecific().

23e3b1e665 Filter: Some people can't pronounce "postfixify" correctly. Let's try "linearize" instead.
This is just a naming change.

20c6ea70cc Filter: Making the filter state thread local.
While having the filter code still reentrant if we really need,
the compiler can now do constant propagation and address the
thread local storage directly to save some computation time.

0b1e1e1a00 BGP: Output Local AS number in show protocol
Useful for implementation of agents implementing the SNMP-BGP MIB, which
requires the local AS of a session to be specified.

Thanks to Jan-Philipp Litza for the patch.

e0835db4f1 BGP: Dynamic BGP
Support for dynamically spawning BGP protocols for incoming connections.
Use 'neighbor range' to specify range of valid neighbor addresses, then
incoming connections from these addresses spawn new BGP instances.

4a50c8bd03 BGP: Handle corner cases in event ordering
When BGP connection is opened, it may happen that rx hook (with remote
OPEN) is called before tx hook (for local OPEN). Therefore, we need to do
internal changes (like setting local_caps) synchronously with OPENSENT
transition and we need to ensure that OPEN is sent before KEEPALIVE.

23ee6b1cd6 BGP: Promiscuous ASN mode
Allow to specify just 'internal' or 'external' for remote neighbor
instead of specific ASN. In the second case that means BGP peers with
any non-local ASNs are accepted.

875cc073b0 Nest: Update handling of temporary attributes
The temporary atttributes are no longer removed by ea_do_prune(), but
they are undefined by store_tmp_attrs() protocol hooks. This fixes
several bugs where temporary attributes were removed when they should
not or not removed when they should be. The flag EAF_TEMP is no longer
needed and was removed.

Update all protocol make_tmp_attrs() / store_tmp_attrs() hooks to use
helper functions and to handle unset attributes properly.

Also fix some related bugs like improper handling of empty eattr list.

9aa77fcceb OSPF: Improved handling of tmpattrs
Keep track of whether OSPF tmpattrs are actually defined for given route
(using flags in rte->pflags). That makes them behave more like real
eattrs so a protocol can define just a subset of them or they can be
undefined by filters.

Do not set ospf_metric2 for other than type 2 external OSPF routes and do
not set ospf_tag for non-external OSPF routes. That also fixes a bug
where internal/inter-area route propagated from one OSPF instance to
another is initiated with infinity ospf_metric2.

Thanks to Yaroslav Dronskii for the bugreport.

2915e711f7 Custom number parser to speed up config parsing
The glibc's generic parser is slow due to its versatility. Specialized
parsers for base-10 and base-16 are much faster and we don't use other
bases.

93af78d2d2 Nest: Do not compare rte.flags during rte_update()
Route flags are mosty internal state of rtable, they are not significant
to whether a route has changed. With the old code, all routes received as
a part of enhanced route refresh are always re-announced to other peers
due to change in REF_STALE.
