dd8f2b2565 zebra: Fix crash during reconnect
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:

Prior to this commit stdout of a process started in a daemon mode was
attached to a calling process.
As a result a calling process hung for infinity.

bc06ff90f5 bgpd: EVPN fix per rd specific type-2 json output
Current Issue:

paths key is not there for
'show bgp l2vpn evpn route rd <rd-id> mac <mac> json' uses
evpn prefix as key for each path.
Replace the evpn prefix with "paths".
This aligned with overall EVPN RIB json output like
'show bgp l2vpn evpn route json'
'show bgp l2vpn evpn route rd <> type 2 json'

Fix:

paths key is added instead of prefix info.

Ticket:#4087461

31d39e7221 isisd: fix rcap tlv double-free crash
A double-free crash happens when a subTLV of the "Router Capability"
TLV is not readable and a previous "Router Capability" TLV was read.

rcap was supposed to be freed later by isis_free_tlvs() ->
free_tlv_router_cap(). In 78774bbcd5 ("isisd: add isis flex-algo lsp
advertisement"), this was not the case because rcap was not saved to
tlvs->router_cap when the function returned early because of a subTLV
length issue.

Always set tlvs->router_cap to free the memory.

Note that this patch has the consequence that in case of subTLV error,
the previously read "Router Capability" subTLVs are kept in memory.

Fixes: 49efc80d34 ("isisd: Ensure rcap is freed in error case")

087943eff8 nhrpd: fixes duplicate auth extension
When an NHRP peer was forwarding a message, it was copying all
extensions from the originally received packet. The authentication
extension must be regenerated hop by hop per RFC2332.
This fix checks for the auth extension when copying extensions
and omits the original packet auth and instead regenerates a new auth extension.

Fix bug #16507

8fb29a38ae isisd: fix update link params after circuit is up
If the link-params are set when the circuit not yet up, the link-params
are never updated.

isis_link_params_update() is called from isis_circuit_up() but returns
immediately because circuit->state != C_STATE_UP. circuit->state is
updated in isis_csm_state_change after isis_circuit_up().

Do not return isis_link_params_update() if circuit->state != C_STATE_UP.

b39cdb3ed4 zebra: Ensure non-equal id's are not same nhg's
The function zebra_nhg_hash_equal is only used
as a hash function for storage of NHG's and retrieval.
If you have say two nhg's:

31 (25/26)
32 (25/26)

This function would return them as being equal.  Which
of course leads to the problem when you attempt to
hash_release 32 but release 31 from the hash.  Then later
when you attempt to do hash comparisons 32 has actually
been freed leaving to use after free situations and shit
goes down hill fast.

This hash is only used as part of the hash comparison
function for nexthop group storage.  Since this is so
let's always return the 31/32 nhg's are not equal at all.

We possibly have a different problem where we are creating
31 and 32 ( when 31 should have just been used instead of 32 )
but we need to prevent any type of hash release problem at all.
This supercedes any other issue( that should be tracked down
on it's own ).  Since you can have use after free situation
that leads to a crash -vs- some possible nexthop group duplication
which is very minor in comparison.

430903f36a ospfd: fix internal ldp-sync state flags when feature is disabled
When enabling "mpls ldp-sync" under "router ospf" ospfd configures
SET_FLAG(ldp_sync_info->flags, LDP_SYNC_FLAG_IF_CONFIG) so internally knowing
that the ldp-sync feature is enabled. However the flag is not cleared when
turning of the feature using "nompls ldp-sync"!
