**- Why I did it**
I'm updating the jinja2 template to support getting SNMP information from the redis configdb.
I'm using the format approved here:
https://github.com/Azure/SONiC/pull/718
This will pave the way for us to decrement using the snmp.yml in the future.
Right now we will still be using both the snmp.yml and configdb to get variable information in order to create the snmpd.conf via the sonic-cfggen tool.
**- How I did it**
I first updated the SNMP Schema in PR #718 to get that approved as a standardized format.
Then I verified I could add snmp configs to the configdb using this standard schema. Once the configs were added to the configdb then I updated the snmpd.conf.j2 file to support the updates via the configdb while still using the variables in the snmp.yml file in parallel. This way we will have backward compatibility until we can fully migrate to the configdb only.
By updating the snmpd.conf.j2 template and running the sonic-cfggen tool the snmpd.conf gets generated with using the values in both the configdb and snmp.yml file.

Why I did it
Arista did not update db with eeprom info. Previous PR had issues that were reverted.
How I did it
Had Arista eeprom class inherit the class that has method to update db. Updated platform API methods for Arista 202012.
How to verify it
In redis-cli the keys and values can be seen. Can use sonic-mgmt testing to verify behavior, and see the chassis platform API methods have not regressed.

Support zero buffer profiles
1. Add buffer profiles and pool definition for zero buffer profiles
2. Support applying zero profiles on INACTIVE PORTS
3. Enable dynamic buffer manager to load zero pools and profiles from a JSON file
- How I did it
Add buffer profiles and pool definition for zero buffer profiles
If the buffer model is static:
* Apply normal buffer profiles to admin-up ports
* Apply zero buffer profiles to admin-down ports
If the buffer model is dynamic:
* Apply normal buffer profiles to all ports
* buffer manager will take care when a port is shut down
Update buffers_config.j2 to support INACTIVE PORTS by extending the existing macros to generate the various buffer objects, including PGs, queues, ingress/egress profile lists
Originally, all the macros to generate the above buffer objects took active ports only as an argument.
Now that buffer items need to be generated on inactive ports as well, an extra argument representing the inactive ports need to be added.
To be backward compatible, a new series of macros are introduced to take both active and inactive ports as arguments
The original version (with active ports only) will be checked first. If it is not defined, then the extended version will be called.
Only vendors who support zero profiles need to change their buffer templates
Enable buffer manager to load zero pools and profiles from a JSON file:
The JSON file is provided on a per-platform basis
It is copied from platform/<vendor> folder to /usr/share/sonic/temlates folder in compiling time and rendered when the swss container is being created.
To make code clean and reduce redundant code, extract common macros from buffer_defaults_t{0,1}.j2 of all SKUs to two common files:
One in Mellanox-SN2700-D48C8 for single ingress pool mode
The other in ACS-MSN2700 for double ingress pool mode
Those files of all other SKUs will be symbol link to the above files
Update sonic-cfggen test accordingly:
* Adjust example output file of JSON template for unit test
* Add unit test in for Mellanox's new buffer templates.
- How to verify it

Run regression test and manually test.

- Why I did it
To include latest fixes.
1. On CMIS modules, after low power configuration, the firmware waited for the module state to be ModuleReady instead of ModuleLowPower causing delays.
2. When connecting Spectrum devices with optical transceivers that support RXLOS, remote side port down might cause the switch firmware to get stuck and cause unexpected switch behavior.
3. On rare occasions, when working with port rates of 1GbE or 10GbE and congestion occurs, packets may get stuck in the chip and may cause switch to hang.
4. When ECMP has high amount of next-hops based on VLAN interfaces, in some rare cases, packets will get a wrong VLAN tag and will be dropped.
5. Using SN4600C with copper or optics loopback cables in NRZ speeds, link may raise in long link up times ( up to 70 seconds).
6. When connecting SN4600C to SN4600C after Fastboot in 50GbE No_FEC mode with a copper cable, the link up time may take ~20 seconds.

#### How I did it
1. Get container names from FEATURE table
2. For each container, collect critical process names from file critical_processes
3. Use “docker exec -it <container_name> bash -c ‘supervisorctl status’” to get processes status inside container, parse the output and check if any critical processes exit

When we update the a sai package downing from a remote server, we need to update the version file as well currently, but the reproducible build feature is not enabled in master, it can only be detected when merging the code into the release branches, such as 202106, 202012, etc.
The reproducible feature is to reduce the build failure, not need to break the build when the version not specified. If version not specified, the best choice is to accept the version from remote server.

#### Why I did it
With current code the delay will take place even if simple 'config reload' command executed and this is not desired.

#### How to verify it

[cherry-pick PR #9123 ]
Why I did it
When sshd realizes that this login can't succeed due to internal device state
or configuration, instead of failing right there, it proceeds to prompt for
password, so as the user does not get any clue on where is the failure point.
Yet to ensure that this login does not proceed, sshd replaces user provided password
with a specific pattern of characters matching length of user provided password.
This pattern is "<BS><LF><CR><DEL>INCORRECT", which is bound to fail.
If user provided length is smaller/equal, the substring of pattern is overwritten.
If user provided length is greater, the pattern is repeated until length is exhausted.
But if the PAM-tacacs plugin would send this password to AAA, the user could get
locked out by AAA, for providing incorrect value.
How I did it
Hence this fix, matches obtained password against the pattern. If match, fail just before
reaching AAA server.
How to verify it
Make sure tacacs is properly configured.
Try logging in as, say "user-A"; ensure it succeeds
Pick another user, say user-B and ensure this user has not logged into this device before (look into /etc/passed & folders under /home)
Disable monit service (as that could fix the issue using disk_check.py)
Start TCP dump for all TACACS servers.
Simulate Read-only disk
Try logging in using user-B.
Verify it fails, after 3 attempts
Stop tcp dump.
TCP dump should show "authentication" for user-A only
