If path->net is NULL in the bgp_path_info_free() function, then bgpd would crash in bgp_addpath_free_info_data() with the following backtrace: (gdb) bt #0 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:51 #1 0x00007ff7b267a42a in __GI_abort () at abort.c:89 #2 0x00007ff7b39c1ca0 in core_handler (signo=11, siginfo=0x7ffff66414f0, context=<optimized out>) at lib/sigevent.c:249 #3 <signal handler called> #4 idalloc_free_to_pool (pool_ptr=pool_ptr@entry=0x0, id=3) at lib/id_alloc.c:368 #5 0x0000560096246688 in bgp_addpath_free_info_data (d=d@entry=0x560098665468, nd=0x0) at bgpd/bgp_addpath.c:100 #6 0x00005600961bb522 in bgp_path_info_free (path=0x560098665400) at bgpd/bgp_route.c:252 #7 bgp_path_info_unlock (path=0x560098665400) at bgpd/bgp_route.c:276 #8 0x00005600961bb719 in bgp_path_info_reap (rn=rn@entry=0x5600986b2110, pi=pi@entry=0x560098665400) at bgpd/bgp_route.c:320 #9 0x00005600961bf4db in bgp_process_main_one (safi=SAFI_MPLS_VPN, afi=AFI_IP, rn=0x5600986b2110, bgp=0x560098587320) at bgpd/bgp_route.c:2476 #10 bgp_process_wq (wq=<optimized out>, data=0x56009869b8f0) at bgpd/bgp_route.c:2503 #11 0x00007ff7b39d5fcc in work_queue_run (thread=0x7ffff6641e10) at lib/workqueue.c:294 #12 0x00007ff7b39ce3b1 in thread_call (thread=thread@entry=0x7ffff6641e10) at lib/thread.c:1606 #13 0x00007ff7b39a3538 in frr_run (master=0x5600980795b0) at lib/libfrr.c:1011 #14 0x000056009618a5a3 in main (argc=3, argv=0x7ffff6642078) at bgpd/bgp_main.c:481 Add a null-check protection to fix this problem.

Not a big deal except commit 1315d74 modified the prefix_cmp function to allow for a sorted prefix_cmp. In prefix_cmp we were looking at the offset and shift. In the case of vnc we were passing a prefix length of 64 which is the exact length of the remaining data structure for struct prefix_rd. So we calculated a offset of 8 and a shift of 0. The data structures for the prefix portion happened to be equal to 64 bits of data. So we checked that with the memcmp got a 0 and promptly read off the end of the data structure for the numcmp. The fix is if shift is 0 that means thei the memcmp has checked everything and there is nothing to do. Please note: We will still crash if we set the prefixlen > then ~312 bits currently( ie if the prefixlen specifies a bit length longer than the prefix length ). I do not think there is anything to do here( nor am I sure how to correct this either ) as that we are going to have some severe problems when we muck up the prefixlen.

SUMMARY: AddressSanitizer: heap-use-after-free zebra/rib.h:222 in re_list_const_first
This is happening because we are using the dest pointer after a call into
rib_gc_dest. In process_subq_route, we call rib_process() and if the
dest is deleted dest pointer is now garbage. We must reload the
dest pointer in this case.

On shutdown a use after free was being seen of a route table. Basically the pointer was kept around and resent for cleanup. Probably something needs to be unwound to make this better in the future.

When changing the peers sockunion structure the bgp->peer
list was not being updated properly. Since the peer's su
is being used for a sorted insert then the change of it requires
that the value be pulled out of the bgp->peer list and then
put back into as well.
Additionally ensure that the hash is always released on peer
deletion.
Lead to this from this decode in a address sanitizer run.

The list itself was not being cleaned up when the final list entry was
removed, so make sure we do that instead of leaking memory.

Memory leaks are observed in the cleanup code. When “no router bgp" is executed,
cleanup in that flow for aggregate-address command is not taken care.
fixes the below leak:

This commit addresses a memory leak issue in the BGP Flowspec NLRI parsing function. Previously when processing NLRI, dynamically allocated memory to `temp` was not being freed, leading to a memory leak. The commit introduces the necessary code (XFREE) to properly free the temp memory after processing Flowspec NLRI.

This commit ensures proper cleanup by deleting the gm_join_list when a PIM interface is deleted. The gm_join_list was previously not being freed, causing a memory leak.

The function ospf6_router_lsa_contains_adj(), ospf6_gr_check_adjs() and ospf6_find_interf_prefix_lsa() iterate through LSDB and lock each LSA. During testing, it was discovered that the lock count did not reach zero upon termination. The stack trace below indicates the leak. To resolve this issue, it was found that unlocking the LSA before returning from the functions solves the problem. This suggests that there was a missing unlock that caused the lock count to remain nonzero.

The `bgp_vrf->vrf_prd_pretty` string was not properly freed, leading to a memory leak.
This commit resolves the memory leak by freeing the memory allocated for `bgp_vrf->vrf_prd_pretty` before returning from the function.

When `dplane_fpm_nl` receives a route, it allocates memory for a dplane context and calls `netlink_route_change_read_unicast_internal` without initializing the `intf_extra_list` contained in the dplane context. If `netlink_route_change_read_unicast_internal` is not able to process the route, we call `dplane_ctx_fini` to free the dplane context. This causes a crash because `dplane_ctx_fini` attempts to access the intf_extra_list which is not initialized. To solve this issue, we can call `dplane_ctx_route_init`to initialize the dplane route context properly, just after the dplane context allocation.

Bug is reporoduced in case of switching interfaces betwean VRFs.
ospf6d is enabled and configured in each VRF.
'dest' can be removed from the route node in the time when the same
route node waiting processing in another sub-queue.
A route node must only be in one sub-queue at a time.
Details:
1. Config:
interface if0
ipv6 address 2001:db8:cafe:2::2/64
ipv6 nat inside
ipv6 ospf6 area 0.0.0.51
ipv6 ospf6 cost 10
vrf test2
exit
!
interface if1
ipv6 address 2001:db8:cafe:4::1/64
ipv6 nat outside
ipv6 ospf6 area 0.0.0.0
ipv6 ospf6 cost 10
vrf test2
exit
!
router ospf6
ospf6 router-id 2.2.2.2
exit
!
router ospf6 vrf test1
ospf6 router-id 2.2.2.2
exit
!
router ospf6 vrf test2
ospf6 router-id 2.2.2.2
exit
I just quickly switched interfaces between different VRFs (default/test1/test2).

3. What's happen:
We removed unneeded re 0x56267595ae40 while adding re 0x56267595abf0. It was the last connected re,
but rn 0x56267593de90 is still in the connected sub-queue.
Then rib_delnode was called for 0x56267595abf0. (rn 0x56267593de90 is still in the connected sub-queue).
rib_delnode have called rib_meta_queue_add which have checked, that rn is absent in sub-queue RIP/OSPF/ISIS/EIGRP/NHRP
and have added rn in the second sub-queue.

Properly free the dynamically allocated memory held by `str` after its use.
The change also maintains the return value of `nb_cli_apply_changes` by using 'ret' variable.

Properly free the dynamically allocated memory held by `str` after its use.
The change also maintains the return value of `nb_cli_apply_changes` by using `ret` variable.

Previously when updating vertices, edges and subnets, when no update was required
due to existing value matching the new one, memory associated with the new object
was not being freed leading to memory leaks. This commit fixes memory leak by
freeing memory associated with new object when update is unnecessary.

area range nodes when removed from the table. Introducing a new function,
`ospf_range_table_node_destroy` for proper node cleanup, resolved the issue.

`ng` was not properly freed, leading to a memory leak.
The commit calls `nexthop_group_delete` to free memory associated with `ng`.

The shallow copy of attr wasn't freed when there was no valid label for the momentand the function return therefore creating leaks. The leak below are solved by flushing the shallow copy of attr.
