Why I did it
BGP service has always been starting after interface-config. However, recently we discovered an issue where some BGP sessions are unable to establish due to BGP daemon not able to read the interface IP.
This issue was clearly observed after upgrading to FRR 8.2.2. See more details in #12380.
How I did it
Delaying starting BGP seems to be a workaround for this issue.
However, caution is that this delay might impact warm reboot timing and other timing sequences.
This workaround is reducing the probability of hitting the issue by close to 100X. However, this workaround is not bulletproof as test shows. It is still preferrable to have a proper FRR fix and revert this change in the future.
How to verify it
Continuously issuing config reload and check BGP session status afterwards.

- Why I did it
interfaces-config service restarts networking service, during the restart loopback interface address is being removed and reassigned back, leaving loopback without an ipv4 address for a while.
On SONiC startup and config reload interfaces-config and bgp services start in parallel and sometimes
fpmsyncd in bgp attempts bind to loopback while it does not have an address, fails with the log
Exception "Cannot assign requested address" had been thrown in daemon
and exits with rc 0.

fpmsyncd EXITED Jul 20 05:04 AM
zebra RUNNING pid 35, uptime 6:15:05
zsocket EXITED Jul 20 05:04 AM
docker logs bgp
INFO exited: fpmsyncd (exit status 0; expected)
With fpmsyncd dead, configured routes do not appear in the database.
- How I did it
Added ordering dependency on interfaces-config service into bgp.config
- How to verify it
Itself the issue reproduces quite rarely, but one can gain the time interval between networking down and networking up in interfaces-config.sh like this:
diff --git a/files/image_config/interfaces/interfaces-config.sh b/files/image_config/interfaces/interfaces-config.sh

- Why I did it
Profiling the system state on init after fast-reboot during create_switch function execution, it is possible to see few python scripts running at the same time.
This parallel execution consume CPU time and the duration of create_switch is longer than it should be.
Following this finding, and the motivation to ensure these services will not interfere in the future, LLDP is delayed in 90 seconds until the system finish the init flow after fastboot.
- How I did it
Add a timer for LLDP service.
Copy the timer file to the host bin image.
- How to verify it
Run fast-reboot on MLNX platform and observe faster create_switch execution time.

Changes to allow starting per asic services like swss and syncd only if the platform vendor codedetects the asic is detected and notified. The systemd services ordering we want is database->database@->pmon->swss@->syncd@->teamd@->lldp@
There is also a requirement that management, telemetry, snmp dockers can start even if all asic services are not up.
Why I did it
For VOQ chassis, the fabric cards will have 1-N asics. Also, there could be multiple removable fabric cards. On the supervisor, swss and syncd containers need to be started only if the fabric-card is in Online state and respective asics are detected by the kernel. Using systemd, the dependent services can be in inactive state.
How I did it
Introduce a mechanism where all ASIC dependent service wait on its state to be published via PMON to REDIS. Once the subscription is received, the service proceeds to create respective dockers.
For fixed platforms, systemd is unchanged i.e. the service bring up and docker creation happens in the start()/ExecStartPre routine of the .sh scripts.
For VOQ chassis platform on supervisor, the service bringup skips docker creation in the start() routine, but does it in the wait()/ExecStart routine of the .sh scrips.
Management dockers are decoupled from ASIC docker creation.
Before this change, a process running inside every SONiC container dealt with FEATURE table 'auto_restart' field and depending on the value decided whether a container has to be killed or not.
If killed service auto restart mechanism restarts the container.
This change moves the logic from container to the host daemon - hostcfgd.
The 'auto_restart' handling is kept in supervisor-proc-exit-listener but now it is not required for container that wants to support auto restart feature.
hostcfgd refactoring - move feature handling in another class.
override systemd service Restart= setting from hostcfgd.
remove default systemd Restart=always.

- Why I did it
Remove the need to deal with container orchestration logic from the container itself. Leave this logic to the orchestrator - host OS.
- How I did it
hostcfgd configures 'Restart=' value for systemd service.

[multi_asic][vs]: Add dependency in teamd service to start after topology service.
- Why I did it
In multi-asic VS, topology service is run after database service to set up the internal asic topology.
swss and syncd have a dependency to start after topology service is run so that the interfaces are moved to right namespace and created in the right namespace. In case of multi-asic vs, during the initial boot up, when there is no configuration added, teamd service starts and swss/syncd do not start as topology service does not start. Upon loading configuration using config_db or minigraph, swss and sycnd start up , but teamd is not restarted as swss is not stopped and started. This causes teamd to be in a bad state and requires a reload of config.
- How I did it
Add dependency in teamd service to start after topology service is completed.
- How to verify it
No change in single asic vs or platform.
No change in multi-asic regular image.
Change only in multi-asic VS. Bring up a multi-asic VS image without any configration, teamd service will fail to start due to dependency failure. Load minigraph, start topology service, load configuration, ensure all services come up.

Summary: Move teamd functions to a new service script
Motivation: To segregate teamd functions in one common place. fast-reboot script calls teamd functions that should ideally be replaced by a simple call to a service script.
Changes: New teamd service script and path modification from /usr/bin/teamd.sh to /usr/local/bin/teamd.sh
fast-reboot script (in sonic-utilities) modification (to use new teamd.sh to stop teamd) should follow soon after this change.
Verification: VS image tests.
