2022-07-26Netlink: Restrict route replace for IPv6Ondrej Zajicek
Seems like the previous patch was too optimistic, as route replace is still broken even in Linux 4.19 LTS (but fixed in Linux 5.10 LTS) for: ip route add 2001:db8::/32 via fe80::1 dev eth0 ip route replace 2001:db8::/32 dev eth0 It ends with two routes instead of just the second. The issue is limited to direct and special type (e.g. unreachable) routes, the patch restricts route replace for cases when the new route is a regular route (with a next hop address).
2022-07-25Netlink: Simplify handling of IPv6 ECMP routesOndrej Zajicek
When IPv6 ECMP support first appeared in Linux kernel, it used different API than IPv4 ECMP. Individual next hops were updated and announced separately, instead of using RTA_MULTIPATH as in IPv4. This has several drawbacks and requires complex code to merge received notifications to one multipath route. When Linux came with IPv6 RTA_MULTIPATH support, the initial versions were somewhat buggy, so we kept using the old API for updates (splitting multipath routes to sequences of route updates), while accepting both old-style routes and RTA_MULTIPATH routes in scans / notifications. As IPv6 RTA_MULTIPATH support is here for a long time, this patch fully switches Netlink to the IPv6 RTA_MULTIPATH API and removes old complex code for handling individual next hop announces. The required Linux version is at least 4.11 for reliable operation. Thanks to Daniel Gröber for the original patch.
2022-07-24KRT: Scan routing tables separetely on linux to avoid congestionOndrej Zajicek
Remove compile-time sysdep option CONFIG_ALL_TABLES_AT_ONCE, replace it with runtime ability to run either separate table scans or shared scan. On Linux, use separate table scans by default when the netlink socket option NETLINK_GET_STRICT_CHK is available, but retreat to shared scan when it fails. Running separate table scans has advantages where some routing tables are managed independently, e.g. when multiple routing daemons are running on the same machine, as kernel routing table modification performance is significantly reduced when the table is modified while it is being scanned. Thanks Daniel Gröber for the original patch and Toke Høiland-Jørgensen for suggestions.

2022-07-11Dropped the internal kernel protocol table for learnt routes.Maria Matejka
The learnt routes are now pushed all into the connected table, not only the best one. This shouldn't do any damage in well managed setups, yet it should be noted that it is a change of behavior. If anybody misses a feature which they implemented by misusing this internal learn table, let us know, we'll consider implementing it in a better way.

2022-06-27Filter: Implement soft scopesOndrej Zajicek (work)
Soft scopes are anonymous scopes that most likely do not contain any symbol, so allocating regular scope is postponed when it is really needed.
2022-06-27Preexport callback now takes the channel instead of protocol as argumentMaria Matejka
Passing protocol to preexport was in fact a historical relic from the old times when channels weren't a thing. Refactoring that to match current extensibility needs.

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.

2022-05-30Squashing 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.

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 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.
