2022-06-27The show-route CLI command now uses the route export APIMaria Matejka
In the multithreaded environment, it is not supposed that anybody traverses the routing table as the CLI show-route was doing. Now the routing table traversal is gone and CLI won't hold the table locked while computing filters.

2022-05-30Squashing the route attribute structure into one level.Maria Matejka
For now, all route attributes are stored as eattrs in ea_list. This should make route manipulation easier and it also allows for a layered approach of route attributes where updates from filters will be stored as an overlay over the previous version.
2022-05-04Explicit definition structures of route attributesMaria Matejka
Changes in internal API: * Every route attribute must be defined as struct ea_class somewhere. * Registration of route attributes known at startup must be done by ea_register_init() from protocol build functions. * Every attribute has now its symbol registered in a global symbol table defined as SYM_ATTRIBUTE * All attribute ID's are dynamically allocated. * Attribute value custom formatting hook is defined in the ea_class. * Attribute names are the same for display and filters, always prefixed by protocol name. Also added some unit testing code for filters with route attributes.

2021-11-22Route sources have an explicit ownerMaria Matejka
This commit prevents use-after-free of routes belonging to protocols which have been already destroyed, delaying also all the protocols' shutdown until all of their routes have been finally propagated through all the pipes down to the appropriate exports. The use-after-free was somehow hypothetic yet theoretically possible in rare conditions, when one BGP protocol authors a lot of routes and the user deletes that protocol by reconfiguring in the same time as next hop update is requested, causing rte_better() to be called on a not-yet-pruned network prefix while the owner protocol has been already freed. In parallel execution environments, this would happen an inter-thread use-after-free, causing possible heisenbugs or other nasty problems.
2021-11-09Suppressed MRT unused static function warningMaria Matejka
2021-11-09Split route data structure to storage (ro) / manipulation (rw) structures.Maria Matejka
Routes are now allocated only when they are just to be inserted to the table. Updating a route needs a locally allocated route structure. Ownership of the attributes is also now not transfered from protocols to tables and vice versa but just borrowed which should be easier to handle in a multithreaded environment.
2021-10-13RIP fixup + dropping the tmp_attrs mechanism as obsoleteMaria Matejka
2021-10-13Route: moved rte_src pointer from rta to rteMaria Matejka
It is an auxiliary key in the routing table, not a route attribute.

2021-01-22MRT: Fix MP-BGP next hopsOndrej Zajicek (work)
Flag signalling that MP-BGP mode should be used got reset after first batch of routes, so remaining routes were processed without that, leading to missing MP_REACH_NLRI attribute. Thanks to Piotr Wydrych for the bugreport.
2021-01-12MRT: Fix IPv6 table dumpsOndrej Zajicek (work)
Add fake MP_REACH_NLRI attribute with BGP next hop when encoding MRT table dumps for IPv6 routes. That is necessary to encode next hop as NEXT_HOP attribute is not used for MP-BGP. Thanks to Santiago Aggio for the bugreport.
2019-04-02BGP: Separate runtime and config usage of local/remote ip and as fieldsOndrej Zajicek (work)
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.
2018-11-20The MRT protocolOndrej Zajicek (work)
The new MRT protocol is responsible for periodic RIB table dumps in the MRT format (RFC 6396). Also the existing code for BGP4MP MRT dumps is refactored and splitted between BGP to MRT protocols, will be more integrated into MRT in the future. Example: protocol mrt { table "*"; filename "%N_%F_%T.mrt"; period 60; } It is partially based on the old MRT code from Pavel Tvrdik.
