82d57fb7ad CLI: Add timeformat command
Adds ability to override time format of show commands for current CLI session
so that it does not depend on configuration and may ease parsing when CLI is
called from tools.

8a40bccffe BFD: Add option to accept zero checksum for IPv6 UDP packets
Some vendors do not fill the checksum for IPv6 UDP packets.
For interoperability with such implementations one can set
UDP_NO_CHECK6_RX socket option on Linux.

Thanks to Ville O for the suggestion.

e29f134ad9 BFD: Fix build when BFD is disabled
Move bfd_opts grammar inside BFD parser code to avoid dependences between
nest and BFD grammars, which breaks when BFD build is disabled.

Add dummy bfd_opts grammar rule, so protocols can use this nonterminal
even with BFD disabled.

Thanks to Yuri Honegger for the bugreport.

ddf698ec99 Renamed nest/rt.h back to nest/route.h
Some [redacted] (yes, myself) had a really bad idea
to rename nest/route.h to nest/rt.h while refactoring
some data structures out of it.

This led to unnecessarily complex problems with
merging updates from v2. Reverting this change
to make my life a bit easier.

At least it needed only one find-sed command:

    find -name '*.[chlY]' -type f -exec sed -i 's#nest/rt.h#nest/route.h#' '{}' +

aa70e14c9e BFD: Improve handling of AdminDown
According to RFC 5882, system should not interpret the local or remote
session state transition to AdminDown as failure. We followed that for
the local session state but not for the remote session state (which
just triggered a transition of the local state to Down). The patch
fixes that.

We do not properly generate AdminDown on our side, so the patch is
relevant just for interoperability with other systems.

Thanks to Sunnat Samadov for the bugreport.

5ba9878b4f BFD: Fixed reconfiguration issues
After converting BFD to the new IO loop system, reconfiguration never
really worked. Sadly, we missed this case in our testing suite so it
passed under the radar for quite a while.

Thanks to Andrei Dinu <andrei.dinu@digitalit.ro> for reporting and
isolating this issue.

ce7495b49a Refactoring of domains connected to pools 2023-04-25 09:52:28 +02:00

22f54eaee6 Resource pools are now bound with domains.
Memory allocation is a fragile part of BIRD and we need checking that
everybody is using the resource pools in an appropriate way. To assure
this, all the resource pools are associated with locking domains and
every resource manipulation is thoroughly checked whether the
appropriate locking domain is locked.

With transitive resource manipulation like resource dumping or mass free
operations, domains are locked and unlocked on the go, thus we require
pool domains to have higher order than their parent to allow for this
transitive operations.

Adding pool locking revealed some cases of insecure memory manipulation
and this commit fixes that as well.

22a0900ec2 BFD: fixed a request pickup race condition
When several BGPs requested a BFD session in short time, chances were
that the second BGP would file a request while the pickup routine was
still running and it would get enqueued into the waiting list instead of
being picked up.

Fixed this by enforcing pickup loop restart when new requests got added,
and also by atomically moving the unpicked requests to a temporary list
to announce admin down before actually being added into the wait list.

836e857b30 Sockets: Unified API for main and other loops
Now sk_open() requires an explicit IO loop to open the socket in. Also
specific functions for socket RX pause / resume are added to allow for
BGP corking.

And last but not least, socket reloop is now synchronous to resolve
weird cases of the target loop stopping before actually picking up the
relooped socket. Now the caller must ensure that both loops are locked
while relooping, and this way all sockets always have their respective
loop.

c354e8f4c1 Interface updates are asynchronous
Instead of propagating interface updates as they are loaded from kernel,
they are enqueued and all the notifications are called from a
protocol-specific event. This change allows to break the locking loop
between protocols and interfaces.

Anyway, this change is based on v2 branch to keep the changes between v2
and v3 smaller.

99872676df BFD: Improve incoming packet matching
For active sessions, ignore received packets with zero local id and
mismatched remote id. That forces a session timeout instead of an
immediate session restart. It makes BFD sessions more resilient to
packet spoofing.

Thanks to André Grüneberg for the suggestion.
