DEBUG_PCAP can be set True to manually enable pcap debugging when
running bmp tests.
Save bmp pcap in logdir (ie. /tmp/topotests/bgp_bmp.bgp_bmp_X/ instead
of /tmp.

Multiple BMP tests can run in parallel but, when one instance ends,
it kills the BMP server process of all BMP tests.
Save the PID of a BMP server and only kill it at the end.

When configuring the bgp_bmp test with an additional
peer that sends empty AS-PATH, the bmp collector is stopping:
> [2024-10-28 17:41:51] Finished dissecting data from ('192.0.2.1', 33922)
> [2024-10-28 17:41:52] Data received from ('192.0.2.1', 33922): length 195
> [2024-10-28 17:41:52] Got message type: <class 'bmp.BMPRouteMonitoring'>
> [2024-10-28 17:41:52] unpack_from requires a buffer of at least 2 bytes for unpacking 2 bytes at offset 0 (actual buffer size is 0)
> [2024-10-28 17:41:52] TCP session closed with ('192.0.2.1', 33922)
> [2024-10-28 17:41:52] Server shutting down on 192.0.2.10:1789
The parser attempts to read an empty AS-path and considers the length
value as a length in bytes, whereas RFC mentions this value as
definining the number of AS-PAths. Fix this in the parser.

The bgp_bmp and bgp_bmp_vrf tests use similar routines
to test the bmp, but are duplicates. Gather the bgp_bmp
and the bgp_bmp_vrf tests in a single bgp_bmp folder.
- Create a bgpbmp.py library under the bgp_bmp test folder
- The bgp_bmp and bgp_bmp_vrf test are renamed to bgp_bmp_1
and bgp_bmp_2 test.
- Maintain separate folder for config and output results. Adapt
the bgp_bmp library accordingly.
- The json output for bgp_bmp_2 test has no referenc to hostame.

When receiving an SRv6 BGP update, the nexthop tracking is used
to find out the reachability of the BGP update.
> # show bgp ipv6 vpn fd00:200::/64
> Paths: (1 available, best #1)
> [..]
> 4:4::4:4 from 4:4::4:4 (4.4.4.4)
> Origin incomplete, metric 0, localpref 100, valid, internal, best (First path received)
> Extended Community: RT:52:100
> Remote label: 16
> Remote SID: 2001:db8:f4::
> Last update: Mon Mar 11 11:50:04 2024
The IPv6 address used is the "Remote SID". Actually, this value is
incomplete. Remote SID stands for the attribute value received in BGP,
while the label value determines a complement of SRv6 SID value. The
transposition technique authorises that in BGP, and in the above case,
the incoming BGP update has used the transposition length.
When there is a transposition in the SID attribute available, use the
real SID address. The nexthop tracking will use that forged address.

During zebra shutdown, the main pthread and the FPM pthread can
deadlock if the FPM pthread is in fpm_reconnect(). Each pthread
tries to use event_cancel_async() to cancel tasks that may be
scheduled for the other pthread - this leads to a deadlock as
neither thread can progress.
This adds an atomic boolean that's managed as each pthread
enters and leaves the cleanup code in question, preventing the
two threads from running into the deadlock.

Notice that the 5 second delay for the max med expires at 29 seconds but the show routes
on r2 does not even begin until 34 seconds, long after the max med has expired and the

Let's relax the max-med timer to 30 seconds and modify the test to wait a bit longer for
both finding it and expiring timer.
