ConfigDBConnector in supervisor-proc-exit-listener uses default parameter to connect CONFIG_DB (connect by 127.0.0.1:6379) which would fail at non-host network mode container, because they are not sharing the same network and socket.
How I did it
Add a new parameter use_unix_socket_path to this script to indicate whether to use socket to connect CONFIG_DB.
How to verify it
Build image and install it, kill critical processes in container and container crushed.
In #15080, there was a command added to re-add 127.0.0.1/8 to the lo
interface when the networking configuration is being brought down.
However, the trigger for that command is `down`, which, looking at
ifupdown2 configuration files, runs immediately after 127.0.0.1/16 is
removed. This means there may be a period of time where there are no
loopback addresses assigned to the lo interface, and redis commands will
fail.
Fix this by changing this to pre-down, which should run well before
127.0.0.1/16 is removed, and should always leave lo with a loopback
address.

Add dhcp_server ipv4 feature to SONiC.
HLD: sonic-net/SONiC#1282
How I did it
To be clarify: This container is disabled by INCLUDE_DHCP_SERVER = n for now, which would cause container not build.
Add INCLUDE_DHCP_SERVER to indicate whether to build dhcp_server container
Add docker file for dhcp_server, build and install kea-dhcp4 inside container
Add template file for dhcp_server container services.
Add entry for dhcp_server to FEATURE table in config_db.

Build image with INCLUDE_DHCP_SERVER = y to verify:
Image can be install successfully without crush.
By config feature state dhcp_server enabled to enable dhcp_server.
* [swss] Chassis db clean up optimization and bug fixes
This commit includes the following changes:
- Fix for regression failure due to error in finding CHASSIS_APP_DB in
pizzabox (#PR 16451)
- After attempting to delete the system neighbor entries from
chassis db, before starting clearing the system interface entries,
wait for sometime only if some system neighbors were deleted.
If there are no system neighbors entries deleted for the asic coming up,
no need to wait.
- Similar changes for system lag delete. Before deleting the
system lag, wait for some time only if some system lag memebers were
deleted. If there are no system lag members deleted no need to wait.
- Flush the SYSTEM_NEIGH_TABLE from the local STATE_DB. While asic
is coming up, when system neigh entries are deleted from chassis ap
db (as part of chassis db clean up), there is no orchs/process running to
process the delete messages from chassis redis. Because of this, stale system
neigh are entries present in the local STATE_DB. The stale entries result in
creation of orphan (no corresponding data path/asic db entry) kernel neigh
entries during STATE_DB:SYSTEM_NEIGH_TABLE entries processing by nbrmgr (after
the swss serive came up). This is avoided by flushing the SYSTEM_NEIGH_TABLE from
the local STATE_DB when sevice comes up.

Enabling kdump by default for cisco-8000 by setting crashkernel cmdline arg in device installer.conf.
After bootup, sonic-kdump-config wipes crashkernel arg from /host/grub/grub.cfg, and resets USE_KDUMP in /etc/default/kdump-tools, so kdump will not be enabled on subsequent reboot.

chassis-packet: Update arp_update script for FAILED and STALE check (#16311)
1. Fixing an issue with FAILED entry resolution retry.
Neighbor entries in arp table may sometimes enter a FAILED state when the far end is down and reports the state as follows:
2603:10e2:400:3::1 dev PortChannel19 router FAILED
While the arp_update script handles the entries for FAILED in the following format, the above was not handled due to the token location (extra router keyword at index 4):
2603:10e2:400:3::1 dev PortChannel19 FAILED
The former format may appear if an arp resolution is tried on a link that is known but the far end goes down, e.g., pinging a STALE entry while the far end is down.
2. Refreshing STALE entries to make sure the far end is reachable.
STALE entries for some backend ports may appear in chassis-packet when no traffic is received for a while on the port. When the far end goes down, it is expected for BFD to stop sending packets on the session for which the far end is not reachable. But as the entry is known as stale, on the Cisco chassis, BFD keeps sending packets. Refreshing the stale entry will keep active links as reachable in the neighbor table while the entries for the far end down will enter a failed state. FAILED state entries will be retired and entered reachable when far end comes back up.
* Fix the Loopback0 IPv6 address of LC's in chassis not reachable from peer device's
* Assign the metric vaule for Ipv6 default route learnt via RA message to higher value so that BGP learnt default route is higher priority.

To fix the logic introduced by [[memory_checker] Do not check memory usage of containers which are not created #11129](https://github.com/sonic-net/sonic-buildimage/pull/11129).
There could be a scenario before the reboot, where
1. The `docker service` has stopped
2. In a very short period of time, the monit service performs the `root@sonic:/home/admin# monit status container_memory_telemetry`
In such scenario, the `memory_checker` script will throw an error to the syslog:
```
ERR memory_checker: Failed to retrieve the running container list from docker daemon! Error message is: 'Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))'
```
But, actually, this scenario is a correct behavior, because when the docker service is stopped, the Unix socket is destroyed and that is why we could see the `FileNotFoundError(2, 'No such file or directory'` exception in the syslog.
#### How I did it
Change the log severity to the warning and changed the return value.
#### How to verify it
It is really hard to catch the exact moment described in the `Why I did it` section.
In order to check the logic:
1. Change the Unix socket path to non-existing in [/usr/bin/memory_checker](47742dfc2c/files/image_config/monit/memory_checker (L139)) file on the switch.
2. Execute the `root@sonic:/home/admin# monit restart container_memory_telemetry`
3. Check the syslog for such messages:
```
WARNING memory_checker: Failed to retrieve the running container list from docker daemon! Error message is: 'Error while fetching server API version: ('Connection aborte
d.', FileNotFoundError(2, 'No such file or directory'))'
INFO memory_checker: [memory_checker] Exits without checking memory usage since container 'telemetry' is not running!
```
What I did:
Added flag in sonic_version.yml to see if compiled image is secured or non-secured. This is done using build/compile time environmental variable SECURE_UPGRADE_MODE as define in HLD: https://github.com/sonic-net/SONiC/blob/master/doc/secure_boot/hld_secure_boot.md
This flag does not provide the runtime status of whether the image has booted securely or not. It's possible that compile time signed image (secured image) can boot on non secure platform.
Why I did:
Flag can be used for manual check or by the test case.

SONiC changes:
1. Support Spectrum4 ASIC FW binary building.
2. Support new SDK sx-obj-desc lib building since new SAI need it.
3. Remove SX_SCEW debian package from Mellanox SDK build since we are no longer using it (we use libxml2 instead).
4. Update SAI, SDK, FW to version 4.6.1020/2012.1020/SAIBuild2305.25.0.3
SDK/FW bug fixes
1. In SPC-1 platforms: Fastboot mode is not operational for Split port with Force mode in 50G speed
SFP modules are kept in disabled state after set LPM (low power mode) on/off for at least 3 minutes.
2. When preforming fast boot from an old SDK version (currently installed) to a newer one (target version), and the system was initially loaded with a new SDK version (past version), and the system has not been wiped, under specific conditions, the fast boot would use the past version's data and may fail.
SDK/FW Features
1. On SN2700 all ports can support y cable by credo
SAI bug Fixes
1. When creating an ACL rule with SAI_ACL_ENTRY_ATTR_FIELD_SRC_IP/SAI_ACL_ENTRY_ATTR_FIELD_DST_IP enabled, and then disabling the field by setting enable=false, a match on L3_type=IPv4 will remain programmed for the rule Issue resolved after the fix
2. Allow the max scale of virtual routers to be configure for SPC-1, SPC-2, SPC-3 when fastboot enable
3. Remove default hash key of SRC_MAC, DST_MAC and ETH_TYPE

Why I did it
For route registry service, in order to block hijacked routes, IBGP session needs to be set up from BGP sentinel service to SONiC, and BGP sentinel service advertise the same route with higher local-preference and no export community. So that SONiC takes the route from BGP sentinel as the best path and does not advertise the route to EBGP peers.
In order to do that, new route-maps are needed. So this change adds a new set of templates, keeping BGPSentinel peers out of the other templates.

Microsoft ADO (number only): 24451346
How I did it
Add sentinel_community in constants.yml, route from BGPSentinel do not match this community will be denied.
Add support to convert BGPSentinel related configuration in the BGPPeerPassive element of the minigraph to a new BGP_SENTINELS table in CONFIG_DB
Add a new set of "sentinels" templates to docker-fpm-frr
Add a new BGP peer manager to bgpcfgd, to add neighbors from the BGP_SENTINELS table using the "sentinels" templates
Add a test case for minigraph.py, making sure the BGPSentinel and BGPSentinelV6 elements create BGP_SENTINELS DB entry.
Add a set of test cases for the new sentinels templates in sonic-bgpcfgd tests.
Add sonic-bgp-sentinel.yang and a set of testcases for the yang file.
How to verify it
Testcases and UT newly added would pass.
Setup IPv4 and IPv6 BGPSentinel services in minigraph, and load minigraph, show CONFIG_DB and "show runningconfig bgp", configuration would be loaded successfully.
Using t1-lag topo and setup IBGP session from BGPSentinel to SONiC loopback address, IBGP session would up.
Advertise route from BGPSentinel to T1 with sentinel_community, higher local-preference and no-export communiyt. In T1, show bgp route, the result is "Not advertise to any EBGP peer".
Withdraw the route in BGPSentinel, in T1, route would advertise to EBGP peers.
Advertise route from T1 that does not match sentinel_community, in T1, would not see the route in show bgp route.
