2022-05-21BGP: Display neighbor port on show protocolOndrej Zajicek
2022-05-15BGP: Improve tx performance during feed/flushOndrej Zajicek
The prefix hash table in BGP used the same hash function as the rtable. When a batch of routes are exported during feed/flush to the BGP, they all have similar hash values, so they are all crowded in a few slots in the BGP prefix table (which is much smaller - around the size of the batch - and uses higher bits from hash values), making it much slower due to excessive collisions. Use a different hash function to avoid this. Also, increase the batch size to fill 4k BGP packets and increase minimum BGP bucket and prefix hash sizes to avoid back and forth resizing during flushes. This leads to order of magnitude faster flushes (on my test data).
2022-05-04Removing the route scope attribute. Use custom attributes instead.Maria Matejka
The route scope attribute was used for simple user route marking. As there is a better tool for this (custom attributes), the old and limited way can be dropped.
2022-05-04Moved route preference to eattrsMaria Matejka
2022-05-04Joined the RTA igp_metric and EA igp_metric attributesMaria Matejka
2022-05-04Conf: Allowing keyword redefinitionMaria Matejka
Some tokens are both keywords and symbols. For now, we allow only specific keywords to be redefined; in future, more of the keywords may be added to this category. The redefinable keywords must be specified in any .Y file as follows: toksym: THE_KEYWORD ; See proto/bgp/config.Y for an example. Also dropped a lot of unused terminals.
2022-05-04Moved advertising router info (FROM attribute) to eattrsMaria Matejka
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.

2022-05-04Unified attribute and filter typesMaria Matejka
This commit removes the EAF_TYPE_* namespace completely and also for route attributes, filter-based types T_* are used. This simplifies fetching and setting route attributes from filters. Also, there is now union bval which serves as an universal value holder instead of private unions held separately by eattr and filter code.

2022-05-04Special attribute types for enumsMaria Matejka
2022-04-06BGP uses lp_save / lp_restore instead of linpool flushingMaria Matejka
It is too cryptic to flush tmp_linpool in these cases and we don't want anybody in the future to break this code by adding an allocation somewhere which should persist over that flush. Saving and restoring linpool state is safer.

2022-02-06BGP: Implement flowspec validation procedureOndrej Zajicek (work)
Implement flowspec validation procedure as described in RFC 8955 sec. 6 and RFC 9117. The Validation procedure enforces that only routers in the forwarding path for a network can originate flowspec rules for that network. The patch adds new mechanism for tracking inter-table dependencies, which is necessary as the flowspec validation depends on IP routes, and flowspec rules must be revalidated when best IP routes change. The validation procedure is disabled by default and requires that relevant IP table uses trie, as it uses interval queries for subnets.
