defeb96286 [installer]: Prevent filesystem corruption (#7264)
This improvement reads current SONiC version directly from `/proc/cmdline`.
it supports `grub/aboot/uboot` bootloaders.

**Code snippet**:
```bash
cat /proc/cmdline | sed -n 's/^.*loop=\/*image-\(\S\+\)\/.*$/\1/p'
```

**Description**:
```
-n         don't print lines
s          substitute
^.*        matches anything before the <image_version>
loop=      matches <loop> kernel parameter
\/*image-  matches <image_version> prefix
\(\S\+\)   matches <image_version> group and assigns it to \1
\/.*$      matches anything after the <image_version>
\1         replace everything with <image_version>
p          print it
```
closes #6267

#### Why I did it
* To fix #6267

#### How I did it
* Fixed installer scripts

#### How to verify it
1. Write invalid SONiC version to sonic_version.yml
2. Run SONiC-To-SONiC update

[e1031] add GbE and higig port to E1031 port_config.ini (#7208) (#7224)
Why I did it
These ports are being enumerated by the latest SAI. But they are not defined in port_config.ini.

SONiC end up trying to delete these 3 ports and hit SAI error and crash.

How I did it
Add the GbE and the 2 HiGig ports in the port_config.ini.

How to verify it
Put the port_config.ini on a device crashing with port deleting. load minigraph and the crash stopped.

d7979df5f4 [baseimage]: specify gid for redis group. (#7249)
Problem:
Default groupadd for redis, takes 1000 by default. This forces, subsequently created admin group to get 1001.
As all TACACS users are created with 1000 as their gid, they end up in redis group.

Fix:
Create redis group *after* admin group is created
Add a check that admin group id is 1000

3cee45c298 [monit] Avoid monit error log by removing "-l" from monit_swss|buffermgrd (#7236)
Avoid the following error messages while dynamic buffer calculation is enabled
```
ERR monit[491]: 'swss|buffermgrd' status failed (1) -- '/usr/bin/buffermgrd -l' is not running in host
```

Change /usr/bin/buffermgrd -l to /usr/bin/buffermgrd. The buffermgrd is started by -l for traditional model or -a for dynamic model. So we need to use the common section of both.

c63b59698c [container_checker] Exclude the 'always_disabled' container from expected running container list (#7217)
Signed-off-by: Yong Zhao yozhao@microsoft.com

Why I did it
Since we introduced a new value always_disabled for the state field in FEATURE table, the expected running container list
should exclude the always_diabled containers. This bug was found by nightly test and posted at here: issue. This PR fixes #7210.

How I did it
I added a logic condition to decide whether the value of state field of a container was always_disabled or not.

How to verify it
I verified this on the device str-dx010-acs-1.

[202012][dockers][supervisor] Increase event buffer size for process exit listener; Set all event buffer sizes to 1024 (#7203)
#### Why I did it

Backport of https://github.com/Azure/sonic-buildimage/pull/7083 to the 202012 branch.

To prevent error [messages](https://dev.azure.com/mssonic/build/_build/results?buildId=2254&view=logs&j=9a13fbcd-e92d-583c-2f89-d81f90cac1fd&t=739db6ba-1b35-5485-5697-de102068d650&l=802) like the following from being logged:

```
Mar 17 02:33:48.523153 vlab-01 INFO swss#supervisord 2021-03-17 02:33:48,518 ERRO pool supervisor-proc-exit-listener event buffer overflowed, discarding event 46
```

This is basically an addendum to https://github.com/Azure/sonic-buildimage/pull/5247, which increased the event buffer size for dependent-startup. While supervisor-proc-exit-listener doesn't subscribe to as many events as dependent-startup, there is still a chance some containers (like swss, as in the example above) have enough processes running to cause an overflow of the default buffer size of 10.

This is especially important for preventing erroneous log_analyzer failures in the sonic-mgmt repo regression tests, which have started occasionally causing PR check builds to fail. Example [here](https://dev.azure.com/mssonic/build/_build/results?buildId=2254&view=logs&j=9a13fbcd-e92d-583c-2f89-d81f90cac1fd&t=739db6ba-1b35-5485-5697-de102068d650&l=802).

I set all supervisor-proc-exit-listener event buffer sizes to 1024, and also updated all dependent-startup event buffer sizes to 1024, as well, to keep things simple, unified, and allow headroom so that we will not need to adjust these values frequently, if at all.

23c7940787 [docker-gbsyncd-vs] Run new gbsyncdmgrd in lieu of deprecated gbsyncd_startup.py (#7154)
To improve management of docker-gbsyncd-vs. gbsyncd_startup.py simply spawned syncd processes and then exited. In that case, supervisord would no longer manage any processes in the container, and thus there was no way to know if a critical process had exited.

I recently created gbsyncdmgrd to be a more complete, robust replacement for gbsyncd_startup.py.

NOTE: This PR is dependent on the inclusion of gbsyncdmgrd in the sonic-sairedis repo. A submodule update is pending at

72a38526f8 [determine-reboot-cause] Support 'Kernel Panic' reboot cause (#7153)
Signed-off-by: Yong Zhao yozhao@microsoft.com

Why I did it
If device reboot was caused by kernel panic, then we need retrieve and store the key information into the symbol file previous-reboot-cause.json. The CLI show reboot-cause will read this file to get the reason of previous reboot.

This PR is related to PR in sonic-utilities repo: Azure/sonic-utilities#1486

How I did it
The string variable previous_reboot_cause will be parsed to check whether it contains the keyword Kernel Panic. If it did, then store the keyword and time information into a dictionary.

How to verify it
I verified this change on a virtual testbed.

admin@vlab-01:/host/reboot-cause$ more previous-reboot-cause.json

[202012][sonic-config-engine] Parse AutoNegotiation element from LinkMetadata section of minigraph file (#7166)
Backport of https://github.com/Azure/sonic-buildimage/pull/7031 to the 202012 branch

#### Why I did it

To enable parsing the `AutoNegotiation` element from the LinkMetadata section of minigraph file

#### How I did it

Parse the value `AutoNegotiation` element from the `LinkMetadata` section of minigraph file. If the element is present, an `autoneg` key will be added to the port in the `PORT` table of Config DB with a value of either `0` or `1`

If an `autoneg` value is present in port_config.ini, the value from the minigraph will take precedence, overriding that value.

Also remove `AutoNegotiation` and `EnableAutoNegotiation` elements from the `DeviceInfo` section, as we will use this data in the `LinkMetadata` section to determine whether to enable auto-negotiation for a port.
