      Nest: Update handling of temporary attributes · 875cc073
      Ondřej Zajíček authored
      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.

      Custom route attributes · 265419a3
      Maria Matejka authored
      For local route marking purposes, local custom route attributes may be
      defined. These attributes are seamlessly stripped after export filter to
      every real protocol like Kernel, BGP or OSPF, they however pass through
      pipes. We currently allow at most 256 custom attributes.
      This should be much faster than currently used bgp communities
      for marking routes.

      Filter: fixed eattr cached pointer · 1771f70d
      Jan Maria Matejka authored
      Use ACCESS_RTE to guard **f_rte, use ACCESS_EATTRS to guard **f_eattrs.
      Use f_rta_cow() before writing to rta or eattrs, use f_rte_cow() before
      writing preference (stored in rte).
      Do not access eattrs indirectly through (*f_rte)->attrs->eattrs, it is
      way too slow. The cached pointer is faster.

      Nest: Removing separate tmpa from route propagation · 13c0be19
      Jan Maria Matejka authored
      This is a fundamental change of an original (1999) concept of route
      processing inside BIRD. During import/export, there was a temporary
      ea_list created which was to be used instead of the another one inside
      the route itself.
      This led to some confusion, quirks, and strange filter code that handled
      extended route attributes. Dropping it now.
      The protocol interface has changed in an uniform way -- the
      `struct ea_list *attrs` argument has been removed from store_tmp_attrs(),
      import_control(), rt_notify() and get_route_info().

      Filter: make bgpmask literals real constructors · e8bc64e3
      Jan Maria Matejka authored
      The bgpmask literals can include expressions. This is OK but they have
      to be interpreted as soon as the code is run, not in the time the code
      is used as value.
      This led to strange behavior like rewriting bgpmasks when they shan't
      be rewritten:
      	function mask_generator(int as)
      		return [= * as * =];
      	function another()
      	bgpmask m1;
      	bgpmask m2;
      		m1 = mask_generator(10);
      		m2 = mask_generator(20);
      		if (m1 == m2) {
      			print("strange"); # this would happen
      Moreover, sending this to CLI would cause stack overflow and knock down the
      whole BIRD, as soon as there is at least one route to execute the given
      filter on.
      	show route filter bgpmask mmm; bgppath ppp; { ppp = +empty+; mmm = [= (ppp ~ mmm) =]; print(mmm); accept; }
      The magic match operator (~) inside the bgpmask literal would try to
      resolve mmm, which points to the same bgpmask so it would resolve
      itself, call the magic match operator and vice versa.
      After this patch, the bgpmask literal will get resolved as soon as it's
      assigned to mmm and it also will return a type error as bool is not
      convertible to ASN in BIRD.

      Filter: recursion to loop · 7c601e6b
      Jan Maria Matejka authored
      It was supposed to do tail-recursion in interpret() but it didn't
      compile as such. Converting it to loop makes a significant filter
      performance improvement for flat filters.

      Filter: Instruction codes named as enum · 5a14df39
      Maria Jan Matejka authored
      The two-letter instructions were quite messy but they could be easily
      read from memory dumps. Now GDB (since 2012) supports pretty printing
      enum values and GCC checks the switch construction for missing enum
      values so we are converting the nice two-byte values to enums.
      Anyway, the enum still keeps the old two-byte values to be able to read
      the instruction codes even without GDB from plain memory dump.

      RAdv: Support for more specific routes (RFC 4191) · 2a95e633
      Michal 'vorner' Vaner authored
      The patch implements Default Router Preferences and More-Specific Routes
      (RFC 4191) for RAdv protocol, allowing to announce router preference and
      more specific routes in router advertisements. Routes can be exported to
      RAdv like to regular routing protocols.
      Some cleanups, bugfixes and other changes done by Ondrej Zajicek.
