previously "make reset" was expecting user input from the terminal to do its job
setting UNATTENDED to any non-zero string will allow "make reset" to run without interactive confirmation
- Why I did it
This is the backport to 202211 from master (see PR #12207)
When doing automated builds of SONiC images, we need to reset the working repositories between each build.
- How I did it
Adding an environment variable that is read by Makefile.work
- How to verify it
running
UNATTENDED=1 make reset
should make an automatic reset of all working directories
Why I did it
Support to upgrade packages, do better cleanup after the build.
How I did it
Remove the no use preference version control file after the build.
How to verify it
Why I did it
Docker build has a low rate of hanging up.
It hangs on different steps. So, it looks like a bug in docker daemon.
How I did it
Start a daemon process to scan running time more than 1 hours, and kill the process.

Advance hw-mgmt service to V.7.0020.4100
Add missing thermal sensors that are supported by hw-mgmt package
Delay system health service before hw-mgmt has started on Mellanox platform in order to avoid reading some sensors before ready.

- How I did it
1. Update hw mgmt version
2. Add missing sensors
3. Delay service

Why I did it
By specifying 'status_led' 'controllable' to false for psu section, it means the platform is not yet supporting psu status led
How I did it
specify 'status_led' 'controllable' to false for psu section
How to verify it
by running test in pdb, manually add {'status_led' : {'controllable' : False}} in dictionary
this flag will be able to get False and skip testing:

- Why I did it
Added platform specific script to be invoked during SAI failure dump. Added some generic changes to mount /var/log/sai_failure_dump as read write in the syncd docker
- How I did it
Added script in docker-syncd of mellanox and copied it to /usr/bin
- How to verify it
Manual UT and new sonic-mgmt tests
Why I did it
Fix some unreliability seen on emmc device with some AMD CPUs
How I did it
Added a kernel parameter to add quirks to
It depends on a sonic-linux-kernel change to work properly but will be a no-op without it.
The quirk added is SDHCI_QUIRK2_BROKEN_HS200 used to downgrade the link speed for the eMMC.
Why I did it
On a supervisor card in a chassis, syncd/teamd/swss/lldp etc dockers are created for each Switch Fabric card. However, not all chassis would have all the switch fabric cards present. In this case, only dockers for Switch Fabrics present would be created.
system-health indicates errors in this scenario as it is expecting dockers for all Switch Fabrics (based on NUM_ASIC defined in asic.conf file).
system-health process error messages were also altered to indicate which container had the issue; multiple containers may run processes with the same name, which can result in identical system-health error messages, causing ambiguity.
How I did it
Port container_checker logic from #11442 into service_checker for system-health.
How to verify it
Bringup Supervisor card with one or more missing fabric cards. Execute 'show system-health summary'. The command should not report failure due to missing dockers for the asics on the fabric cards which are not present.
Why I did it
To address error sometimes seen when running sonic-mgmt test_stress_routes.py::test_announce_withdraw_route on 720DT-48S
How I did it
Update boot0 logic to set platform specific varlog size for 720DT-48S
How to verify it
Verified that /var/log size increased and error is no longer observed when running test
Why I did it
1. fix chassis test_set_fans_led case
2. fix chassis get_name case mismatch issue
3. fix fan_drawer test_set_fans_speed
4. fix component test_components test case
How I did it
Add corresponding configuration into chassis json file
How to verify it
Run platform tests cases to verify these failure cases
- Why I did it
In to-sonic and multi-asic KVM-test, pretest sometimes failed. Reason is rsyslogd process can not start in teamd container. Because rsyslog.conf is empty caused by sonic-cfggen execute failed
- How I did it
If sonic-cfggen -d execute failed, execute without -d because the template file has the default value.
- How to verify it
Build image and test it over 40 times, all passed pretest.

Why I did it
High CPU utilization by entropy.py
How I did it
Remove entropy script as it does not work anymore and is no longer needed for bullseye(202205).
In Buster(202012) the max available poolsize (entropy_avail) for entropy is 4096 and our entropy.py script was based on this value. With the change in kernel to bullseye on 202205 this entropy poolsize was changed to 256 which also causes our script to fail.
This script was initially added to provide SW assistance to improve the system entropy value available early on in the Sonic boot sequence on buster.
On bullseye (Linux kernel 5.10) this is no longer needed as this feature has been improved.
How to verify it
run "top" command to check CPU usage.

1. Fixed bug in recovery mechanism in case of I2C error when trying to access the XSFP module.
2. On the NVIDIA Spectrum-2 switch, when receiving a packet with Symbol Errors on ports that are configured to cut-thought mode, a pipeline might get stuck.
3. On the Spectrum-2 and Spectrum-3 switch, if you enable ECN marking and the port is in split mode, traffic sent to the port under congestion (for example, when connecting two ports with a total speed of 50GbE to a single 25GbE port) is not marked.
4. Modifying existing entry/Adding new one when switch is at its maximum capacity (full by maximum allowed entries from any type such as routes, FDB, and so forth), will fail with an error.
5. When many ports are active (e.g., 70 ports up), and the configuration of shared buffer is applied on the fly, occasionally, the firmware might get stuck.
6. When a system has more than 256 ACL rules, on rare occasion, removing/adding rules may cause some ACL rules not to work.
7. On SN2201 system, on RJ45 port, the link might appear in 'down' state even if it operations properly.
8. Layer 4 port information is not initialized for BFD packet event. To address the issue, remote peer UDP port information was added in BFD packet event.
9. When setting LAG as a SPAN analyzer, the distributor mode of the LAG members was not taken into account. It may happen that the LAG member with distributor mode disabled will be set as a SPAN analyzer port.

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.
6.2.5. Ceasing To Be an Advertising Interface
shutting down the system.
In such cases, the router SHOULD transmit one or more (but not more
than MAX_FINAL_RTR_ADVERTISEMENTS) final multicast Router
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.

During docker build, host files can be passed to the docker build through
docker context files. But there is no straightforward way to transfer
the files from docker build to host.
This feature provides a tricky way to pass the cache contents from docker
build to host. It tar's the cached content and encodes them as base64 format
and passes it through a log file with a special tag as 'VCSTART and VCENT'.

Eariler the SDK stat polling was erroneously set to once every msec
which is far more frequent than required by SWSS. The new setting, which
is consistent with other vendor SKUs, is once a second. The net result
is reduced CPU MHz by syncd.
Why I did it
fix DX010 fan drawer and watchdog platform test case issues
How I did it
1. Add fan_drawer get_maximum_consumed_power support
2. Adjust maximum watchdog timeout value check
How to verify it
Run test_fan_drawer and test_watchdog test cases.
