For the upcoming rework of protocol state information propagation,
we need some more eattr types to be defined.
These types are probably not defined completely and before using
them for route attributes, you should check that they don't lack
some crucial methods.
The original algorithm assumed principles not consistent with the RFC
and could have lead to false invalids.
Also added filter tests showing also how the ASPA literals are used in
the static protocol.
Enum types existed on semantic level, but not on syntactic level,
so they could not be used in filter code.
Generate filter grammar for enum types based on CF_ENUM() declarations.
Thanks to lbz for the bugreport.
Unify grammar for set_atom and switch_atom to avoid inconsistencies
between them. Fix errors in documentation related to case statement
and set type. Change 'vpnrd' to 'rd' to be consistent with the filter
language.
Thanks to Mikhail Mayorov for bugreport.
There is an IP table for every ROA table, holding special records
combining all known ROAs for every top-prefix.
The ROA digestor is now an IP digestor, running over the auxiliary
table.
Add route attribute gw_mpls_stack to make MPLS stack of route nexthop
accessible from filters. Its type is T_CLIST, which is really not correct
(as it is a list, while T_CLIST is a set). Therefore, we keep this
attribute *undocumented* and it will be *changed* without further notice.
Based on a patch from Trisha Biswas <tbiswas@fastly.com>, thanks!
Add a new protocol offering route aggregation.
User can specify list of route attributes in the configuration file and
run route aggregation on the export side of the pipe protocol. Routes are
sorted and for every group of equivalent routes new route is created and
exported to the routing table. It is also possible to specify filter
which will run for every route before aggregation.
Furthermore, it will be possible to set attributes of new routes
according to attributes of the aggregated routes.
This is a work in progress.
Original work by Igor Putovny, subsequent cleanups and finalization by
Maria Matejka.
This is a split-commit of the neighboring aggregator branch
with a bit improved lvalue handling, to have easier merge into v3.
Added a code for computing hash of filter values.
This is a split-commit of the neighboring aggregator branch
with improved lvalue and attribute handling.
