    #### What I did

    Removed check_frr_patch mock to fix UT running on python3.7

    #### How I did it

    Removed the mock

    #### How to verify it

    Fix fast-reboot DB migration (#2734)

    Fix DB migrator logic for migrating fast-reboot table, fixing #2621 db_migrator.

    How I did it
    Checking if fast-reboot table exists in DB.

    How to verify it
    Verified manually, migrating after fast-reboot and after cold/warm reboot.

    Enhance the logic to wait for all buffer tables to be removed in _clear_qos (#2720)

    - What I did
    This is an enhancement of PR #2503

    - How I did it
    On top of waiting for BUFFER_POOL_TABLE to be cleared from APPL_DB, we need to wait for KEY_SET and DEL_SET as well.
    KEY_SET and DEL_SET are designed to accommodate the APPL_DB entries that were updated by manager daemons but have not yet been handled by the orchagent.
    In this case, even if the buffer tables are empty, entries in KEY_SET or DEL_SET will be in the buffer tables later on. So, we need to wait for key set tables as well.
    Do not delay for traditional buffer manager because it does not remove any buffer table.
    Provide a CLI option to print the detailed message if there is any table item which still exists

    - How to verify it
    Manually test and unit test

    - Previous command output (if the output of a command-line utility has changed)
    Running command: /usr/local/bin/sonic-cfggen  -d --write-to-db -t /usr/share/sonic/device/x86_64-mlnx_msn2410-r0/ACS-MSN2410/buffers_dynamic.json.j2,config-db -t /usr/share/sonic/device/x86_64-mlnx_msn2410-r0/ACS-MSN2410/qos.json.j2,config-db -y /etc/sonic/sonic_version.yml

    - New command output (if the output of a command-line utility has changed)
    Only with option --verbose there are new output. Without the option, the output is the same as it is.

    Remove timer from FAST_REBOOT STATE_DB entry and use finalizer (#2621)

    This should come along with sonic-buildimage PR (sonic-net/sonic-buildimage#13484) implementing fast-reboot finalizing logic in finalize-warmboot script and other submodules PRs utilizing the change.

    This PR should come along with the following PRs as well:
    sonic-net/sonic-swss-common#742
    sonic-net/sonic-platform-daemons#335
    sonic-net/sonic-sairedis#1196

    This set of PRs solves the issue sonic-net/sonic-buildimage#13251

    What I did
    Remove the timer used to clear fast-reboot entry from state-db, instead it will be cleared by fast-reboot finalize function implemented inside finalize-warmboot script (which will be invoked since fast-reboot is using warm-reboot infrastructure).

    As well instead of having "1" as the value for fast-reboot entry in state-db and deleting it when done it is now modified to set enable/disable according to the context.

    As well all scripts reading this entry should be modified to the new value options.

    How I did it
    Removed the timer usage in the fast-reboot script and adding fast-reboot finalize logic to warm-reboot in the linked PR.
    Use "enable/disable" instead of "1" as the entry value.

    How to verify it
    Run fast-reboot and check that the state-db entry for fast-reboot is being deleted after finalizing fast-reboot and not by an expiring timer.

    [GCU] Add vlanintf-validator (#2697)

    What I did
    Fix the bug of GCU vlan interface modification. It should call ip neigh flush dev after removing interface ip.
    The fix is basically following config CLI's tradition.

    How I did it
    Add vlanintf service validator to check if extra step of ip neigh flush is needed.

    How to verify it
    GCU E2E test in dualtor testbed.

    [show][muxcable] increase timeout for displaying HW_STATUS (#2712)

    What I did
    probe mux direction not always return success.

    Sample output of: while [ 1 ]; do date; show mux hwmode muxdirection; show mux status; sleep 1; done

    Mon 27 Feb 2023 03:12:25 PM UTC

    -----------  --------  --------  ------------  ---------------------------
    Ethernet16   standby   healthy   inconsistent  2023-Feb-25 07:55:18.269177
    If we increase the timeout to 0.5 secs to get the values back from ycabled, this will remove the inconsistency issue, and display the consistent values, because while telemetry is going on, the time to get actual mux value takes significantly longer than 0.1 seconds.

    PORT         STATUS    HEALTH    HWSTATUS      LAST_SWITCHOVER_TIME

    worst-case CLI return time could be 16 seconds for 32 ports. on avg each port is 200 mSec if telemetry is going, but on average show command will return in < 1 sec for all 32 ports.

    Add support of secure warm-boot (#2532)

    - What I did
    Add support of secure warm-boot to SONiC.
    Basically, warm-boot is supporting to load a new kernel without doing full/cold boot.
    That is by loading a new kernel and exec with kexec Linux command. As a result of that, even when the Secure Boot feature is enabled, still a user or a malicious user can load an unsigned kernel, so to avoid that we added the support of the secure warm boot.
    More Description about this feature can be found in the Secure Boot HLD: sonic-net/SONiC#1028

    - How I did it
    In general, Linux support it, so I enabled this support by doing the follow steps:

    I added some special flags in Linux Kernel when user build the sonic-buildimage with secure boot feature enabled.
    I added a flag "-s" to the kexec command
    Note: more details in the HLD above.

    - How to verify it
    * Good flow:
    manually just install with sonic-installed a new secure image (a SONiC image that was build with Secure Boot flag enabled)
    after the secure image is installed, do:
    warm-reboot
    Check now that the new kernel is really loaded and switched.
    * Bad flow:
    Do the same steps 1-2 as a good flow but with an insecure image (SONiC image that was built without setting Secure Boot enabled)
    After the insecure image is installed, and triggered warm-boot you should get an error that the new unsigned kernel from the unsecured image was not loaded.
    Automation test - TBD

    [db_migrator] make LOG_LEVEL_DB migration more robust (#2651)

    It could be that LOG_LEVEL_DB includes some invalid data and/or a KEY_SET that is not cleaned up due to an issue, for example we observed _gearsyncd_KEY_SET set included in the LOG_LEVEL_DB and preserved in warm reboot. However, this key is not of type hash which leads to an exception and migration failure. The migration logic should be more robust allowing users to upgrade even though some daemon has left overs in the LOG_LEVEL_DB or invalid data is written.

    - What I did
    To fix migration issue that leads to device configuration being lost.

    - How I did it
    Wrap the logic in try/except/finally.

    - How to verify it
    202205 -> 202211/master upgrade.

    Secure upgrade (#2337)

    #### What I did
    Added support for secure upgrade

    #### How I did it
    It includes image signing during build (in sonic buildimage repo) and verification during image install (in sonic-utilities).
    HLD can be found in the following PR: https://github.com/sonic-net/SONiC/pull/1024
    #### How to verify it
    Feature is used to allow image was not modified since built from vendor. During installation, image can be verified with a signature attached to it.
    In order for image verification - image must be signed - need to provide signing key and certificate (paths in SECURE_UPGRADE_DEV_SIGNING_KEY and SECURE_UPGRADE_DEV_SIGNING_CERT in rules/config) during build , and during image install, need to enable secure boot flag in bios, and signing_certificate should be available in bios.

    #### Feature dependencies
    In order for this feature to work smoothly, need to have secure boot feature implemented as well.
    The Secure boot feature will be merged in the near future.

    Removed function get_queue_port() to decrease the times of connecting database.

    [GCU] Ignore bgpraw table in GCU operation (#2628)

    What I did
    After the previous fix #2623 , GCU still fails in the rollback operation. The bgpraw table should be discard in all GCU operation.
    Thus, I change get_config_db_as_json function to crop out "bgpraw" table.

    How I did it
    Pop "bgpraw" table if exists.

    How to verify it
    Unittest

    [GCU] Ignore bgpraw in GCU applier (#2623)

    What I did
    show run all output will include bgpraw for business needs. GCU ipv6 test will update BGP_NEIGHBOR table which caused bgpraw content change, which will make the apply-patch operation fail. The solution is to add bgpraw to ignored tables.

    How I did it
    Add new added bgpraw table to ignored backend table.

    How to verify it
    Existing Unit test and local E2E GCU test.

    [warm-reboot] Use kexec_file_load instead of kexec_load when available (#2608)

    On some dev VMs, warm reboot on a VS image fails. Specifically, after
    kexec is called and the new kernel starts, the new kernel tries to load
    the initramfs, but fails to do so for whatever reason. There may be
    messages about gzip decompression failing and that it's corrupted.

    After some experimentation, it was found that when first loading the new
    kernel and initramfs into memory, using the `kexec_file_load` syscall
    (`-s` flag in kexec) worked fine, whereas using the default `kexec_load`
    syscall resulted in a failure. It's unknown why `kexec_file_load` worked
    fine when `kexec_load` didn't; there shouldn't be any difference for
    non-secure boot kernels, as far as I can tell. What was seen, however,
    was that when taking a KVM dump in the failure case, the memory that
    stored the initramfs had differences compared to what was on disk. It's
    unknown what caused these differences.

    As a workaround (and as a bit of a feature enhancement), use the `-a`
    flag with kexec, which tells it to use `kexec_file_load` if available,
    and `kexec_load` if it's not available or otherwise fails. armhf doesn't
    support `kexec_file_load`, whereas arm64 gained support for
    `kexec_file_load` in the 5.19 kernel (we're currently on 5.10). `amd64`
    has supported `kexec_file_load` since 3.17. This also makes it possible
    to do kexec on secure boot systems, where the kernel image must be
    loaded via `kexec_file_load`.

    [show] Add bgpraw to show run all (#2537)

    #### What I did
    Add bgpraw output to `show runningconfiguration all`
    ```
    Requirements:
    1. current `show runningconfig` will print all the ConfigDB in a json format, we need to add a new key-value into the json output "bgpraw" with a long string value
    2. The long string value should be the output of `vtysh -c "show run"`. It is normally multiline string, may include special characters like \". Need to make sure the escaping properly
    3. We do not need to insert the key-value into ConfigDB is not existing there
    4. If ConfigDB already has the key-value, we do not need to override it by vtysh command output
    5. Not break multi-asic use
    ```
    #### How I did it
    Generate bgpraw output then append it to `show runnningconfiguration all`'s output
    #### How to verify it
    Mannual test
    #### Previous command output (if the output of a command-line utility has changed)

    Fix issue: unconfigured PGs are displayed in watermarkstat (#2556)

    - What I did
    All the PGs between minimal and maximal indexes are displayed regardless of whether they are configured.
    Originally, watermark counters were enabled for all PGs, so there is no issue.
    Now, watermark counters are enabled only for PGs with buffer configured, eg. if PG 0/2/3/4/6, is configured, PG 0-6 will be displayed, which is confusing by giving users a feeling that PG 7 is lost

    - How I did it
    Display valid PGs only

    - How to verify it
    Manually test and unit test.

    [generate_dump] Optimize the execution time of 'show techsupport' CLI by parallel function execution (#2512)

    - What I did
    Optimize the execution time of the 'show techsupport' script.

    - How I did it
    The show techsupport CLI command calls the generate_dump bash script. In the script, there are a many functions that do the next scenario:

    1. Run some CLI command
    2. Save output from step 1 to the temporary file
    3. Append the temporary file from step 2 to the `/var/dump/sonic_dump_XXXX.tar` file
    4. Delete the temporary file from step 2
    This PR will add the execution of these functions in parallel manner. Also, it will not spawn too many processes to not waste all CPU time.

    - How to verify it
    First test scenario

    Run the `time show techsupport` CLI command and compare the execution time to the original script (with no parallelism), the execution time will be decreased by 10-20%.
    Second test scenario

    1. Stuck the FW by using next commands
    	a. mcra /dev/mst/mt52100_pci_cr0 0xa01e4 0x10
    	b. mcra /dev/mst/mt52100_pci_cr0 0xa05e4 0x10
    	c. mcra /dev/mst/mt52100_pci_cr0 0xa07e4 0x10
    	d. mcra /dev/mst/mt52100_pci_cr0 0xa09e4 0x10
    	e. mcra /dev/mst/mt52100_pci_cr0 0xa0be4 0x10
    	f. mcra /dev/mst/mt52100_pci_cr0 0xa0de4 0x10
    	g. mcra /dev/mst/mt52100_pci_cr0 0xa0fe4 0x10
    2. Run the `time show techsupport` CLI command and compare the execution time to the original script (with no parallelism), the execution time will be decreased by up to 50% because inside the script we launch CLI commands with `timeout --foreground 5m`.

    [db_migrator] Fix migration of Loopback data: handle all Loopback interfaces (#2560)

    Fix the issue where cross branch upgrades (base DB version 1_0_1) lead to a OA crash due to a duplicate IP2ME route being added when there are more than one Loopback interfaces.

    The issue happens as in current implementation lo is hardcoded to be replaced as Loopback0.
    When the base image's APP DB has more than one IP assigned to lo interface, upon migration, all the IPs are assinged to same loopback Loopback0. This is incorrect, as in newer images different IPs are assinged to distinct Loopback interfaces.

    How to verify it
    Verified on a physical testbed that this change fixes the OA crash issue.
    Also added a unit test to catch this issue in PR tests.

    Optimize the execution time of the 'show techsupport' script to 5-10%, (#2504)

    - What I did
    Optimize the execution time of the 'show techsupport' script to 5-10%.

    - How I did it
    The show techsupport CLI command calls the generate_dump bash script. In the script, there are a many functions that do the next scenario:

    1. Run some CLI command
    2. Save output from step 1 to the temporary file
    3. Append the temporary file from step 2 to the `/var/dump/sonic_dump_XXXX.tar` file
    4. Delete the temporary file from step 2
    This PR removes the 3 and 4 step from those functions and creates a new function save_to_tar() which will add to .tar archive the whole directory with temporary files (which means it will not spawn a tar -v -rhf ... process for each temporary file)

    - How to verify it
    Run the time show techsupport CLI command and compare the execution time to the original script, the execution time will be decreased by 5-10%.

    [show]Fix show route return code on error (#2542)

    - What I did
    Fix show route return command to return error code on failure cases. The parameter return_cmd=True in run_command will suppress the return code and return success even in error scenarios.

    - How I did it
    When run command is called with return_cmd = True, modified its return to include return code, which can then be used to assess if there is an error by the caller

    - How to verify it
    Added UT to verify it

    - Previous command output (if the output of a command-line utility has changed)
    root@sonic:/home/admin# show ip route 123
    % Unknown command: show ip route 123

    root@sonic:/home/admin# echo $?
    0

    - New command output (if the output of a command-line utility has changed)
    root@sonic:/home/admin# show ip route 123
