we have
(gdb) p *path->attr->aspath
$1 = {refcnt = 3, segments = 0x0, json = 0x0, str = 0x55723d0b7470 "", str_len = 0, asnotation = ASNOTATION_PLAIN}
It looks like this aspath is empty, resulting in a size 0 and NULL pointer for path->attr->aspath->segments which leads to the SIGSEGV
fixe: return 0 when segments is null.

pimd: allow resolving bsr via directly connected secondary address (backport) (backport #17217)
|
|
This only matters to single hop nodes that are adjacent to the bsr. More common
with IPv6 where LL address is used in PIM as the primary address. If the BSR IP
happens to be an address on the same interface, the receiving pim router
rejects the BSR address because it expects the BSR IP to resolve via the LL address
even if we have a connected route for the same BSR IP subnet. Effectively, we want to
allow rpf to be resolved via secondary IPs with connected routes on the same interface,
and not limit them to primary addresses.

(cherry picked from commit 51612593f7f747d0003a48a41367be87d3ea5361)
|
|
Fix several issues in sourcing AIGP attribute:
1) AIGP should not be set as default for a redistributed route or a
static network. It should be set by config instead.
2) AIGP sourced by "set aigp-metric igp-metric" in a route-map does
not set the correct value for a redistributed route.
3) When redistribute a connected route like loopback, the AGIP (with
value 0) is sourced by "set aigp-metric igp-metric", but the
attribute is not propagated as the attribute flag is not set.

bgpd: fix route selection with AIGP (backport #17093)
|
|
Fix and adjust the topotest post the fix for route selection with
AIGP.
When there are multiple IGP domains (OSPF in this case), the nexthop
for a BGP route with the AIGP attribute must be resolved in its own
IGP domain.
The changes in r2/bgpd.conf and r3/bgpd.conf are needed as incorrect
IGP metrics are received from NHT for the recursive nexthops. Once
the issue is resolved, the changes can be reverted.

fpm_enqueue_rmac_table expects an fpm_rmac_arg* as its argument.
The issue can be reproduced by dropping the TCP session using:
ss -K dst 127.0.0.1 dport = 2620
I used Fedora 40 and frr 9.1.2 and I got the gdb backtrace:
