2019-05-21Filter: Store variables and function arguments on stackJan Maria Matejka
2019-05-20Filter: Making the filter state thread local.Jan Maria Matejka
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.

2019-03-14Nest: Update handling of temporary attributesOndrej Zajicek (work)
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.
2019-03-06OSPF: Improved handling of tmpattrsOndrej Zajicek (work)
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.

2019-02-25Custom number parser to speed up config parsingMaria Matejka
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.

2019-02-22Nest: Do not compare rte.flags during rte_update()Ondrej Zajicek (work)
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.

2019-02-20Filter refactoring: dropped the recursion from the interpreterMaria Matejka
This is a major change of how the filters are interpreted. If everything works how it should, it should not affect you unless you are hacking the filters themselves. Anyway, this change should make a huge improvement in the filter performance as previous benchmarks showed that our major problem lies in the recursion itself. There are also some changes in nest and protocols, related mostly to spreading const declarations throughout the whole BIRD and also to refactored dynamic attribute definitions. The need of these came up during the whole work and it is too difficult to split out these not-so-related changes.

2019-02-20Filter refactoring: Drop the roa check specific f_instMaria Matejka
2019-02-20Filter refactoring: The constant f_val is simply included inside the instructionMaria Matejka
With 32 bits, size of the args is 12 bytes, the f_val is 20 bytes. With 64 bits, size of the args is 24 bytes, the f_val the same. This is not so nice on 32 bits, anyway the f_inst itself is 24 vs. 32 bytes and the overall size of filters must be 32k of instructions to get to one megabyte of RAM eaten by f_inst. Therefore it seems to be improbable for common user to get into problems with this change.
