Why I did it
Vendor platform may require running platform specific pre-shutdown routine before shutting down the syncd process which runs the SAI and vendor sdk instance.
How I did it
Added a platform script hook which will be executed if the plugin script is provided by the platform in device//plugins/
Fixe #12047. After the c++ implementation of the sonic-db-cli, sonic-db-cli PING command tries to initialize the global database for all instances database starting. If all instance database-config.json are not ready yet. it will crash and generate core file. PR sonic-net/sonic-swss-common#701 only fix the crash and the process abortion.

Upgrade from old image always requires squashfs mount to get the next image FW binary. This can be avoided if we put FW binary under platform directory which is easily accessible after installation:
admin@r-spider-05:~$ ls /host/image-fw-new-loc.0-dirty-20230208.193534/platform/fw-SPC.mfa
/host/image-fw-new-loc.0-dirty-20230208.193534/platform/fw-SPC.mfa
admin@r-spider-05:~$ ls -al /tmp/image-fw-new-loc.0-dirty-20230208.193534-fs/etc/mlnx/fw-SPC.mfa
lrwxrwxrwx 1 root root 66 Feb 8 17:57 /tmp/image-fw-new-loc.0-dirty-20230208.193534-fs/etc/mlnx/fw-SPC.mfa -> /host/image-fw-new-loc.0-dirty-20230208.193534/platform/fw-SPC.mfa
- Why I did it
202211 and above uses different squashfs compression type that 201911 kernel can not handle. Therefore, we avoid mounting squashfs altogether with this change.
- How I did it
Place FW binary under /host/image-/platform/mlnx/, soft links in /etc/mlnx are created to avoid breaking existing scripts/automation.
/etc/mlnx/fw-SPCX.mfa is a soft link always pointing to the FW that should be used in current image
mlnx-fw-upgrade.sh is updated to prefer /host/image-/platform/mlnx location and fallback to /etc/mlnx in squashfs in case new location does not exist. This is necessary to do image downgrade.
- How to verify it
Upgrade from 201911 to 202205
202205 to 201911 downgrade
202205 -> 202205 reboot
ONIE -> 202205 boot (First FW burn)

Why I did it
Some products might experience an occasional IO failure in the communication between CPU and SSD.
Based on some research it could be attributable to some device not handling ATA NCQ (Native Command Queue).
This issue currently affect 4 products:
DCS-7170-32C*
DCS-7170-64C
DCS-7060DX4-32
DCS-7260CX3-64
How I did it
This change disable NCQ on the affected drive for a small set of products.
How to verify it
When the fix is applied, these 2 patterns can be found in the dmesg.

Which release branch to backport (provide reason below if selected)
Go's runtime (and dockerd inherits this) uses own DNS resolver implementation by default on Linux.
It has been observed that there are some DNS resolution issues when executing ```docker pull``` after first boot.
Consider the following script:
```

While /etc/resolv.conf has the correct content and ping (and any other utility that uses libc's DNS resolution implementation) works correctly
docker is unable to resolve the hostname and falls back to default [::1]:53. This started to happen after PR https://github.com/sonic-net/sonic-buildimage/pull/13516 has been merged.
As you can see from the log, dockerd is able to pick up the correct /etc/resolv.conf only after 5 sec since first try. This seems to be somehow related to the logic in Go's DNS resolver
https://github.com/golang/go/blob/master/src/net/dnsclient_unix.go#L385.
There have been issues like that reported in docker like:
- https://github.com/docker/cli/issues/2299
- https://github.com/docker/cli/issues/2618
- https://github.com/moby/moby/issues/22398
Since this starts to happen after inclusion of resolvconf package by
above mentioned PR and the fact I can't see any problem with that (ping,
nslookup, etc. works) the choice is made to force dockerd to use cgo
(libc) resolver.

- How I did it
Regarding buffer settings, originally, there are two lossless PGs and queues 3, 4. In dual ToR scenario, the lossless traffic from the leaf switch to the uplink of the ToR switch can be bounced back.
To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:

fixes#12907
When the management interface IP address configuration changes from dynamic to static the DNS configuration (retrieved from the DHCP server) in /etc/resolv.conf remains uncleared. This leads to a DNS configuration pointing to the wrong nameserver. To make the behavior clear DNS configuration received from DHCP should be cleared.
- How I did it
Use resolvconf package for managing DNS configuration. It is capable of tracking the source of DNS configuration and puts the configuration retrieved from the DHCP servers into a separate file. This allows the implementation of DNS configuration cleanup retrieved from DHCP during networking reconfiguration.
- How to verify it
Ensure that the management interface has no static configuration.
Check that /etc/resolv.conf has DNS configuration.
Configure a static IP address on the management interface.
Verify that /etc/resolv.conf has no DNS configuration.
Remove the static IP address from the management interface.
Verify that /etc/resolv.conf has DNS configuration retrieved form DHCP server.

Changing the default config knob value to be True for killing radv, due to the reasons below:
Killing RADV is to prevent sending the "cease to be advertising interface" protocol packet.
RFC 4861 says this ceasing packet as "should" instead of "must", considering that it's fatal to not do this.
In active-active scenario, host side might have difficulty distinguish if the "cease to be advertising interface" is for the last interface leaving.

In such cases, the router SHOULD transmit one or more (but not more

Advertisements on the interface with a Router Lifetime field of zero.
In the case of a router becoming a host, the system SHOULD also
depart from the all-routers IP multicast group on all interfaces on
which the router supports IP multicast (whether or not they had been
advertising interfaces). In addition, the host MUST ensure that
subsequent Neighbor Advertisement messages sent from the interface
have the Router flag set to zero.

What I did:

How I did:
During build time mask only those feature/services that are disabled explicitly. Some of the features ((eg: teamd/bgp/dhcp-relay/mux/etc..)) state is determine run-time so for those feature by default service will be up and running and then later hostcfgd will mask them if needed.
So Default behavior will be
init_cfg.json.j2 during build time make state as disabled then mask the service
init_cfg.json.j2 during build time make state as another jinja2 template render string than do no mask the service
init_cfg.json.j2 during build time make state as enabled then do not mask the service

Why I did it
There is an issue on the Arista PikeZ platform (using T3.X2: BCM56274) while running SONiC. If the 'syncd' container in SONiC is restarted, the expected behaviour is that syncd will automatically restart/recover; however it does not and always fails at create_switch due to BCM SDK kmod DMA operation cancellation getting stuck.

Reloading the BCM SDK kmods allows the switch init to continue properly.
How I did it
If BCM SDK kmods are loaded, unload and load them again on syncd docker start script.
How to verify it
Steps to reproduce:
In SONiC, run 'docker ps' to see current running containers; 'syncd' should be present.
Run 'docker stop syncd'
Wait ~1 minute.
Run 'docker ps' to see that syncd is missing.
Check logs to see messages similar to the above.

Why I did it
The current lazy installer relies on a filename sort for both unpack and configuration steps. When systemd services are configured [started] by multiple packages the order is by filename not by the declared package dependencies. This can cause the start order of services to differ between first-boot and subsequent boots. Declared systemd service dependencies further exacerbate the issue (e.g. blocking the first-boot script).
The current installer leaves packages un-configured if the package dependency order does not match the filename order.
This also fixes a trivial bug in [Build]: Support to use symbol links for lazy installation targets to reduce the image size #10923 where externally downloaded dependencies are duplicated across lazy package device directories.
How I did it
Changed the staging and first-boot scripts to use apt-get:
dpkg -i /host/image-$SONIC_VERSION/platform/$platform/*.deb
becomes
apt-get -y install /host/image-$SONIC_VERSION/platform/$platform/*.deb
when dependencies are detected during image staging.
How to verify it

* [202012][Arista] Fix cmdline generation during warm-reboot from 201811/201911 (#11161)
Issue fixed: when performing a warm-reboot or fast-reboot from 201811 or 201911 to 202012 the kernel command line contains duplicate information. This issue is related to a change that was made to make 202012 boot0 file more futureproof.
A cold reboot brings everything back into a clean slate though not always desirable.
Changes done:
Added some logic to properly detect the end of the Aboot cmdline when cmdline-aboot-end delimiter is not set (clean case)
Added some logic to regenerate the Aboot cmdline when cmdline-aboot-end is set but duplicate parameters exists before (dirty case). Reorganized some code to handle duplicate parameter handling in the allowlist.

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.
