- Why I did it
Initially, we used Monit to monitor critical processes in each container. If one of critical processes was not running
or crashed due to some reasons, then Monit will write an alerting message into syslog periodically. If we add a new process
in a container, the corresponding Monti configuration file will also need to update. It is a little hard for maintenance.
Currently we employed event listener of Supervisod to do this monitoring. Since processes in each container are managed by
Supervisord, we can only focus on the logic of monitoring.
- How I did it
We borrowed the event listener of Supervisord to monitor critical processes in containers. The event listener will take
following steps if it was notified one of critical processes exited unexpectedly:
The event listener will first check whether the auto-restart mechanism was enabled for this container or not. If auto-restart mechanism was enabled, event listener will kill the Supervisord process, which should cause the container to exit and subsequently get restarted.
If auto-restart mechanism was not enabled for this contianer, the event listener will enter a loop which will first sleep 1 minute and then check whether the process is running. If yes, the event listener exits. If no, an alerting message will be written into syslog.
- How to verify it
First, we need checked whether the auto-restart mechanism of a container was enabled or not by running the command show feature status. If enabled, one critical process should be selected and killed manually, then we need check whether the container will be restarted or not.
Second, we can disable the auto-restart mechanism if it was enabled at step 1 by running the commnad sudo config feature autorestart <container_name> disabled. Then one critical process should be selected and killed. After that, we will see the alerting message which will appear in the syslog every 1 minute.

During ISSU, "mlxsw_minimal" driver still trying to access firmware, in some cases FW could return some wrong critical threshold value which will cause switch shutdown.
**- How I did it**
In order to prevent "mlxsw_minimal" driver from accessing ASIC during ISSU, SDK will raise "OFFLINE" 'udev' event
at the early beginning of such flow. When this event is received, hw-management will remove "mlxsw_minimal" driver.
There is no need to implement the opposite "ONLINE" event since this flow is ended up with "kexec".
**- How to verify it**
repeatedly perform warm reboot, make sure there is no switch shutdown occurred.
Bugs fixes:
All | Kernel | During system reload when CPU is loaded with heavy traffic, a Kernel Panic may occur.
All | Modules, Port split | FW stuck when device rebooted with locked Optical Transceivers in split mode
Spectrum-3 | PFC | On Spectrum-3 systems, slow reaction time to Rx pause packets on 40GbE ports may lead to buffer overflow on servers.
Spectrum-3 | SN4700, Port Split | On rare occasion SN4700, conducting 100G split (4x25G) in NRZ when splitter port 1 or 2 are down, ports 3 and 4 will also go down.
Enahncments:
All | Kernel | new notification on ISSU start, so other kernel drivers can disable any interface to ASIC

Fixes#6445
Because the ipmihelper.py script in the 9332 folder is slightly different than the common one (due to LGTM fixes), when the common one gets copied during build time it causes the workspace/build to become dirty.

**- Why I did it**
On the Mellanox platform, reboot cause is fetched from some certain sysfs which is created by the hw-management service. So determine-reboot-cause service shall start after hw-management, otherwise it could fail due to the related sysfs is not available yet.
**- How I did it**
Add a patch to the hw-management service to make sure determine-reboot-cause service should start after it.

- Improve random number generation during early Sonic initialization by providing SW updates to Linux entropy value.
- Improve handling of platform In-Band management port
This commit provides the following updates to the Nokia ixs7215 platform
1. The Marvell Armada-38x SOC requires SW assistance to improve the system
entropy value available early on in the Sonic boot sequence.
2. The Nokia ixs7215 platform does not have a dedicated Out-Of-Band (OOB) mgmt
port and thus requires additional logic to optionally support configuring
front panel port 48 as an In-Band mgmt port. This commit provides additional
logic to manage and maintain the operation of this In-Band mgmt port.
fix platform driver breakage due to python3 upgrade and fix load minigraph errors with config load_minigraph -y
**- How I did it**

fixed additional "ord" python2 specific code
fixed the jinja templates used by qos reload - the template logic required data to be parsed
**- How to verify it**

run "sudo config load_minigraph -y" and verify configuration
run "show interfaces XXX" and verify output

In rare case can see that xcvrd failed due to "UnboundLocalError: local variable 'label_port' referenced before assignment"
Init "label_port" as None at the beginning of the function, to avoid the case that "label_port" not assigned.
Fix#119
when parallel build is enable, multiple dpkg-buildpackage
instances are running at the same time. /var/lib/dpkg is shared
by all instances and the /var/lib/dpkg/updates could be corrupted
and cause the build failure.
the fix is to use overlay fs to mount separate /var/lib/dpkg
for each dpkg-buildpackage instance so that they are not affecting
each other.

Starting from build (master) 176 the warm reboot on BRCM Platform started to experience syncd crash. Upon further debug by Ying it was determined that the crash was related to the following new change:
[Dynamic buffer calc] Support dynamic buffer calculation (#1338)
Ying also debugged further and found The crash was caused by buffer pool profile setting operation SAI_BUFFER_PROFILE_ATTR_SHARED_DYNAMIC_TH
A case has filed with BRCM while a potential fix was tried by Ying that seems to have addressed this issue and we are making this change available in master branch so that it will allow further feature validation/testing especially in the warm reboot area.
Once an official fix is provided by BRCM, we will then remove this in house fix and apply the official fix.
- How to verify it
Just perform warm reboot with any master code 175 or above you should see this issue or issue the following cmd will also cause the crash: "mmuconfig -p egress_lossy_profile -a 0"
- Dynamically change EEPROM driver based on media type.
- Otherwise, EEPROM INFO and DOM INFO might not be fetched properly and will result in erroneous output.
combine multiple same operation into one operation to reduce
the build steps. this is to avoid max depth exceeded issue
in the build.

**- Why I did it**
As part of migrating SONiC codebase from Python 2 to Python 3
**- How I did it**
- No longer install Python 2 in docker-base-buster or docker-config-engine-buster.
- Install Python 2 and pip2 in the following containers until we can completely eliminate it there:
- docker-platform-monitor
- docker-sonic-mgmt-framework
- docker-sonic-vs
- Pin pip2 version <21 where it is still temporarily needed, as pip version 21 will drop support for Python 2
- Also preform some other cleanup, ensuring that pip3, setuptools and wheel packages are installed in docker-base-buster, and then removing any attempts to re-install them in derived containers
