2022-06-24Allowed optimized exporting of a subprefix treeMaria Matejka
Added an option for export filter to allow for prefiltering based on the prefix. Routes outside the given prefix are completely ignored. Config is simple: export in <net> <filter>;
2022-06-24Table export generalized to allow for exporting from non-tablesMaria Matejka
2022-06-20Import tables are stored as an attribute layer inside the main tables.Maria Matejka
The separate import tables were too memory-greedy, there is no need for them being stored as full-sized tables.
2022-06-17Route attribute storage keeps the previous layersMaria Matejka

There were quite a lot of conflicts in flowspec validation code which ultimately led to some code being a bit rewritten, not only adapted from this or that branch, yet it is still in a limit of a merge.
2022-06-07Fixing FlowSpec validation for v3 internal APIMaria Matejka
Validation is called internally from route table at the same place where nexthop resolution is done. Also accounting for rte->sender semantics change (not a channel but the import hook instead).

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.
2022-05-30Route destination field merged with nexthop attribute; splitting flowspec ↵Maria Matejka
validation result out. As there is either a nexthop or another destination specification (or othing in case of ROAs and Flowspec), it may be merged together. This code is somehow quirky and should be replaced in future by better implementation of nexthop. Also flowspec validation result has its own attribute now as it doesn't have anything to do with route nexthop.
2022-05-26Moved hostentry to eattrMaria Matejka
2022-05-26Moved nexthop from struct rta to extended attribute.Maria Matejka
This doesn't do anything more than to put the whole structure inside adata. The overall performance is certainly going downhill; we'll optimize this later. Anyway, this is one of the latest items inside rta and in several commits we may drop rta completely and move to eattrs-only routes.
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).
2022-05-05All outstanding MPLS label stacks are stored as adataMaria Matejka
2022-05-04Moved route source attribute (RTS_*) to eattrsMaria Matejka
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.
2022-05-04Conf: Symbols are properly scopedMaria Matejka
Now there is a persistent root symbol scope and all scopes have their symbol hashes to store local symbols and not leak any symbol out.
2022-05-04Enforcing certain data structure explicit paddings.Maria Matejka
Implicit paddings have undefined values in C. We want the eattr blocks to be comparable by memcmp and eattrs settable directly by structrure literals. This check ensures that all paddings in eattr and bval are explicit and therefore zeroed in all literals.
