- Why I did it
To upgrade brcm syncd to buster
- How I did it
Updated BCM SAI using kernel version 4.19.0-12 and debian 10 to support buster.
Updated syncd docker from stretch to buster in sonic-buildimage
- How to verify it
Ensured docker is running synd buster.
After upgrade, ensured all BGP peers and ip interfaces are up.
Ping to BGP neighbors is working fine.
Some syncd containers are still based on Debian Stretch, and thus do not have Python 3 available. For these containers, we must still rely on Python 2 to run supervisord_dependent_startup and supervisor-proc-exit-listener.
**- Why I did it**
We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0.
**- How I did it**
- Remove Makefiles and patches for building supervisor package from source
- Install Python 3 supervisor package version 4.2.1 in Buster base container
- Also install Python 3 version of supervisord-dependent-startup in Buster base container
- Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again.
- Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers
Why/How I did:
Make sure first error syslog is triggered based on FAULT TOLERANCE condition.
Added support of repeat clause with alert action. This is used as trigger
for generation of periodic syslog error messages if error is persistent
Updated the monit conf files with repeat every x cycles for the alert action
Some platforms don't leverage the brcm led coprocessor.
However ledinit will try to load a non existing file and exit with an
error code.
This change is a cosmetic fix mostly.
- How to verify it
Boot a platform without the configuration and verify in the syslog that the exit status of ledinit is 0
Boot a platform with the configuration and verify in the syslog that the exit status of ledinit is 0 and the leds are working.
Verified by adding a dumb led_proc_init.soc on an Arista platform which usually doesn't use it.
We want to let Monit to unmonitor the processes in containers which are disabled in `FEATURE` table such that
Monit will not generate false alerting messages into the syslog.

When stopping the swss, pmon or bgp containers, log messages like the following can be seen:
```

```
This is due to the number of programs in the container managed by supervisor, all generating events at the same time. The default event queue buffer size in supervisor is 10. This patch increases that value in all containers in order to eliminate these errors. As more programs are added to the containers, we may need to further adjust these values. I increased all buffer sizes to 25 except for containers with more programs or templated supervisor.conf files which allow for a variable number of programs. In these cases I increased the buffer size to 50. One final exception is the swss container, where the buffer fills up to ~50, so I increased this buffer to 100.

**- Why I did it**
Initially, the critical_processes file contains either the name of critical process or the name of group.
For example, the critical_processes file in the dhcp_relay container contains a single group name
`isc-dhcp-relay`. When testing the autorestart feature of each container, we need get all the critical
processes and test whether a container can be restarted correctly if one of its critical processes is
killed. However, it will be difficult to differentiate whether the names in the critical_processes file are
the critical processes or group names. At the same time, changing the syntax in this file will separate the individual process from the groups and also makes it clear to the user.
Right now the critical_processes file contains two different kind of entries. One is "program:xxx" which indicates a critical process. Another is "group:xxx" which indicates a group of critical processes
managed by supervisord using the name "xxx". At the same time, I also updated the logic to
parse the file critical_processes in supervisor-proc-event-listener script.
**- How to verify it**
We can first enable the autorestart feature of a specified container for example `dhcp_relay` by running the comman `sudo config container feature autorestart dhcp_relay enabled` on DUT. Then we can select a critical process from the command `docker top dhcp_relay` and use the command `sudo kill -SIGKILL <pid>` to kill that critical process. Final step is to check whether the container is restarted correctly or not.
**- Why I did it**
After discussed with Joe, we use the string "/usr/bin/syncd\s" in Monit configuration file to monitor
syncd process on Broadcom and Mellanox. Due to my careless, I did not find this bug during the
previous testing. If we use the string "/usr/bin/syncd" in Monit configuration file to monitor the
syncd process, Monit will not detect whether syncd process is running or not.
If we ran the command `sudo monit procmactch “/usr/bin/syncd”` on Broadcom, there will be three
processes in syncd container which matched this "/usr/bin/syncd": `/bin/bash /usr/bin/syncd.sh
wait`, `/usr/bin/dsserve /usr/bin/syncd –diag -u -p /etc/sai.d/sai.profile` and `/usr/bin/syncd –diag -
u -p /etc/sai.d/said.profile`. Monit will select the processes with the highest uptime (at there
`/bin/bash /usr/bin/syncd.sh wait`) to match and did not select `/usr/bin/syncd –diag -u -p
/etc/sai.d/said.profile` to match.
Similarly, On Mellanox Monit will also select the process with the highest uptime (at there
`/bin/bash /usr/bin/syncd.sh wait`) to match and did not select `/usr/bin/syncd –diag -u -p
/etc/sai.d/said.profile` to match.
That is why Monit is unable to detect whether syncd process is running or not if we use the string “/usr/bin/syncd” in Monit configuration file. If we use the string "/usr/bin/syncd\s" in Monit configuration file, Monit can filter out the process `/bin/bash /usr/bin/syncd.sh wait` and thus can correctly monitor the syncd process.

Since the syncd process running on different platforms will have the different full path names, we
change the full path name of process syncd in the monit config file such that it will be universal and is not for a specific vendor.

Add the same mechanism I developed for the SwSS service in #2845 to the syncd service. However, in order to cause the SwSS service to also exit and restart in this situation, I developed a docker-wait-any program which the SwSS service uses to wait for either the swss or syncd containers to exit.
- What I did
During boot/reload time, wait in a loop to check for bcm initialization.
Break the loop, once sdk is ready to process the 'bcmcmd' request (or) loop count reached the maximum value.
- How I did it
In the existing implementation during syncd start process will sleep for a fixed time (3 secs)
for sdk initialization to happen. But the time taken for sdk initialization is varying for different platforms.
To fix this issue, the syncd start process wait in a loop and check whether sdk is ready to process 'bcmcmd' command.
- How to verify it
Check for syncd process status and interface status.
Check for syslogs and no failures related to syncd should be present.
led start bcm cmd triggers link state notifications.
This is quick fix to avoid such fake link state notifications.

* [device/dell] Added dynamic sai.profile generation
This commit addds new code for generating dynamic sai.profile file.
The sai.profile.j2 will generate the sai.profile dynamically based on
the topology. It will generate the sai.profile under /etc/sai.d/ directory
in syncd. Before syncd is started this J2 file will be run from the start.sh
file from /usr/bin/ directory. Since the sai.profile is dynamically generated
the old sai.profile file is not required so deleted the file for S6100.
It also address couple of more changes for port_config.ini support is added
for speed in the file which can be used later to find the port speed. Also
the buffer_default_t*.j2 file the ports should be from 0 to 64 changed.
Unit tested the code on S6100 for dynamic generation of sai.profile file for
both T0 and T1 and the file was created in /etc/sai.d/sai.profile
Similarly tested the sonic binary on S6000 to make sure that the sai.profile is
copied from the /usr/share/sonic/hwsku/sai.profile to /etc/sai.d/sai.profile.
