2020-05-08Nest: Recursive bgp routesMikael Magnusson
Allow recursive routes if they reference a route with a hight igp_metric. Max depth set to 10.
2020-05-01Fixed a harmless warning in production buildMaria Matejka

2020-05-01Nest: Added const to ea_show just to declare that this shouldn't really ↵Maria Matejka
change anything
2020-05-01Nest: Several assumptions to tame the static analyzerMaria Matejka
2020-05-01Nest: Assumption in rt-show for not-so-intuitive invariant.Maria Matejka
2020-04-15BGP: Fix handling of 16bit-only ASN translationNasato Goto
The bug generated invalid AGGREGATOR attribute during translation of 32bit ASN to 16bit-only BGP peer. The patch fixes that.
2020-04-09Configuration strings are constant.Maria Matejka
This is merely a const propagation. There was no problem in there.
2020-03-26Filter: Optimize IPv4 prefix setsOndrej Zajicek (work)
Use separate IPv4 and IPv6 implementation of prefix sets. Just this change makes IPv4 prefix sets 60% smaller and 50% faster.
2020-02-21RIP: Demand circuit support (RFC 2091)Ondrej Zajicek (work)
2020-02-04Added missing externMaria Matejka
Thanks to Robert Scheck <bird@robert-scheck.de> who reported it and Toke Høiland-Jørgensen <toke@toke.dk> who suggested this patch.
2020-01-07KRT: Improve syncer code to avoid using temporary data in rtableOndrej Zajicek (work)
The old code stored route verdicts and temporary routes directly in rtable. The new code do not store received routes (it immediately compares them with exported routes and resolves conflicts) and uses internal bitmap to keep track of which routes were received and which needs to be reinstalled. By not putting 'invalid' temporary routes to rtable, we keep rtable in consistent state, therefore scan no longer needs to be atomic operation and could be splitted to multiple events.
2019-12-19KRT: Remove KRF_SYNC_ERROR flagOndrej Zajicek (work)
This info is now stored in an internal bmap. Unfortunately, net.flags is still needed for temporary kernel data.
2019-12-16KRT: Remove KRF_INSTALLED flagOndrej Zajicek (work)
The same information is stored in export_map of kernel protocol.
2019-12-10Nest: Fix bitmap cleanupOndrej Zajicek (work)
Channel currently does not have independent pool and uses protocol pool, which is freed when protocol changes state to down, while channel is still in flushing. Move some some cleanup code to channel_do_flush() so it is done before freeing of protocol pool.
2019-11-26Nest: Use bitmaps to keep track of exported routesOndrej Zajicek (work)
Use a hierarchical bitmap in a routing table to assign ids to routes, and then use bitmaps (indexed by route id) in channels to keep track whether routes were exported. This avoids unreliable and inefficient re-evaluation of filters for old routes in order to determine whether they were exported.
2019-11-26CLI: Fix continuation lines after final oneOndrej Zajicek (work)
Continuation lines may use short form (with space instead of message number), but this should not be done when previous line is final. Thanks to Kenth Eriksson for the bugreport and analysis.
2019-11-04BGP: Add option to reject AS_SETsOndrej Zajicek (work)
There is a pending draft to make them obsolete
2019-11-03Support for address family constantsOndrej Zajicek (work)
We already had them defined on BGP level, but they are more general.
2019-11-03Nest: Fix bug in export tableOndrej Zajicek (work)
For regular channels do not compare src in export table, as we want to keep here only the best (exported) route per network.
2019-10-25Nest: Fix primary flag in show routeOndrej Zajicek (work)
The route is changed by rte_make_tmp_attrs(), so we need to compare net->routes to the original one. Thanks to Kenth Eriksson for the bugreport.
2019-10-19Nest: Fix build without protocolsFabrice Fontaine
(CHECK keyword added by commiter)
2019-10-10Nest: Handle non-MPLS on MPLS case in recursive route updateOndrej Zajicek (work)
When non-MPLS recursive route resolves to MPLS underlying route, then it should get MPLS labels from the the underlying route.
2019-10-10Nest: Handle PtP links in recursive route updateOndrej Zajicek (work)
Underlying (IGP) route may lead to PtP link, in this case it does not need gateway. Which is different than direct route without gateway. When recursive (BGP) route uses PtP route, it should not use recursive next hop as immediate next hop, while for direct routes it should.
2019-10-10Nest: Fix recursive route updateOndrej Zajicek (work)
Missing cleanup can lead to dangling pointer to old next hops.
2019-10-09BGP: AIGP metric support (RFC 7311)Ondrej Zajicek (work)
2019-09-24Nest: Fix bug in export tableOndrej Zajicek (work)
Exported route may be in modified state, we need to get cached one for rte_same() and rta_clone() to work properly.
2019-08-27Channel refeed with import table splitting between routes for one prefixMaria Matejka
2019-08-14Nest: Fix crash in route reload when some channels are not up.Ondrej Zajicek (work)
Only channels that are up can be reloaded.
2019-08-14BGP: implement Adj-RIB-OutOndrej Zajicek (work)
The patch implements optional internal export table to a channel and hooks it to BGP so it can be used as Adj-RIB-Out. When enabled, all exported (post-filtered) routes are stored there. An export table can be examined using e.g. 'show route export table bgp1.ipv4'.
2019-08-06Filter: Allow to use set constants / expressions in path masksOndrej Zajicek (work)
Allow to not only use set literals in path masks, but also existing set constants or set expressions.
2019-08-06Filter: Allow to use sets in path masksOndrej Zajicek (work)
2019-08-06BGP: Improve reconfigurationOndrej Zajicek (work)
Several BGP channel options (including 'next hop self') could be reconfigured without session reset, with just route refeed/refresh. The patch improves reconfiguration code to do it that way.
2019-07-30Conf: Fixed symbol redefinitionMaria Matejka
2019-07-24Merge remote-tracking branch 'origin/mq-filter-stack'Ondrej Zajicek (work)
2019-07-24Nest: VRF of protocol can be explicitly specified as 'default'Ondrej Zajicek (work)
Protocol can have specified VRF, in such case it is restricted to a set of ifaces associated with the VRF, otherwise it can use all interfaces. The patch allows to specify VRF as 'default', in which case it is restricted to a set of iface not associated with any VRF.
2019-07-17BFD: Support for VRFsOndrej Zajicek (work)
Allow multiple BFD instances in separate VRFs, dispatch BFD requests according to VRFs. Thanks to Alexander Zubkov for notice and patches.

2019-07-02Netlink: Handle alien routes with unsorted nexthopsOndrej Zajicek (work)
Nest requires that nexthops are sorted, the kernel protocol have to ensure that for alien routes.
