#### Why I did it
To fix the logic introduced by [[memory_checker] Do not check memory usage of containers which are not created #11129](https://github.com/sonic-net/sonic-buildimage/pull/11129).
There could be a scenario before the reboot, where
1. The `docker service` has stopped
2. In a very short period of time, the monit service performs the `root@sonic:/home/admin# monit status container_memory_telemetry`
In such scenario, the `memory_checker` script will throw an error to the syslog:
```
ERR memory_checker: Failed to retrieve the running container list from docker daemon! Error message is: 'Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))'
```
But, actually, this scenario is a correct behavior, because when the docker service is stopped, the Unix socket is destroyed and that is why we could see the `FileNotFoundError(2, 'No such file or directory'` exception in the syslog.
#### How I did it
Change the log severity to the warning and changed the return value.
#### How to verify it
It is really hard to catch the exact moment described in the `Why I did it` section.
In order to check the logic:
1. Change the Unix socket path to non-existing in [/usr/bin/memory_checker](47742dfc2c/files/image_config/monit/memory_checker (L139)) file on the switch.
2. Execute the `root@sonic:/home/admin# monit restart container_memory_telemetry`
3. Check the syslog for such messages:
```
WARNING memory_checker: Failed to retrieve the running container list from docker daemon! Error message is: 'Error while fetching server API version: ('Connection aborte
d.', FileNotFoundError(2, 'No such file or directory'))'
INFO memory_checker: [memory_checker] Exits without checking memory usage since container 'telemetry' is not running!
```
Why I did it
Networking devices need to be responsive. Such responsiveness is harmed when the CPU change state.
There is a latency penalty when a CPU is idle (e.g C2) and need to exit this state to come back to C1 state.
To prevent this from happening the CPU should be forced to remain in C1 state.
How I did it
Generalize the cstate forcing to C1 to all Arista products.
This is done by adding processor.max_cstate=1 to the kernel cmdline for all CPUs.
Additionally Intel CPUs also need intel_idle.max_cstate=0 to fallback to the acpi_idle driver.
How to verify it
Check that processor.max_cstate=1 is present on the cmdline for AMD CPUs
Check that both processor.max_cstate=1 and intel_idle.max_cstate=0 are present on the cmdline for Intel CPUs
Openssh in Debian Bullseye has been updated to 1:8.4p1-5+deb11u2 to fix CVE-2023-38408.
Since we're building openssh with some patches, we need to update our version as well.

* [swss] Chassis db clean up optimization and bug fixes
This commit includes the following changes:
- Fix for regression failure due to error in finding CHASSIS_APP_DB in
pizzabox (#PR 16451)
- After attempting to delete the system neighbor entries from
chassis db, before starting clearing the system interface entries,
wait for sometime only if some system neighbors were deleted.
If there are no system neighbors entries deleted for the asic coming up,
no need to wait.
- Similar changes for system lag delete. Before deleting the
system lag, wait for some time only if some system lag memebers were
deleted. If there are no system lag members deleted no need to wait.
- Flush the SYSTEM_NEIGH_TABLE from the local STATE_DB. While asic
is coming up, when system neigh entries are deleted from chassis ap
db (as part of chassis db clean up), there is no orchs/process running to
process the delete messages from chassis redis. Because of this, stale system
neigh are entries present in the local STATE_DB. The stale entries result in
creation of orphan (no corresponding data path/asic db entry) kernel neigh
entries during STATE_DB:SYSTEM_NEIGH_TABLE entries processing by nbrmgr (after
the swss serive came up). This is avoided by flushing the SYSTEM_NEIGH_TABLE from
the local STATE_DB when sevice comes up.

Why I did it
For some devices whose log folder size is larger than 200M, for example, 256M, the LOG_FILE_ROTATE_SIZE_KB should be 16M. and
THRESHOLD_KB=$((USABLE_SPACE_KB - (NUM_LOGS_TO_ROTATE * LOG_FILE_ROTATE_SIZE_KB * 2)))
= $(( (VAR_LOG_SIZE_KB * 90 / 100) - RESERVED_SPACE_KB)) - (NUM_LOGS_TO_ROTATE * LOG_FILE_ROTATE_SIZE_KB * 2)))
= $(( (256M * 90 / 100) - 4096)) - (8 * 16M * 2)))
the result would be a negative value

SONiC changes:
Support Spectrum4 ASIC FW binary building.
Support new SDK sx-obj-desc lib building since new SAI need it.
Remove SX_SCEW debian package from Mellanox SDK build since we are no longer using it (we use libxml2 instead).
Update SAI, SDK, FW to version 4.6.1020/2012.1020/SAIBuild2211.25.1.0
SDK/FW bug fixes
In SPC-1 platforms: Fastboot mode is not operational for Split port with Force mode in 50G speed
SFP modules are kept in disabled state after set LPM (low power mode) on/off for at least 3 minutes.
When preforming fast boot from an old SDK version (currently installed) to a newer one (target version), and the system was initially loaded with a new SDK version (past version), and the system has not been wiped, under specific conditions, the fast boot would use the past version's data and may fail.
SDK/FW Features
On SN2700 all ports can support y cable by credo
SAI bug Fixes
When creating an ACL rule with SAI_ACL_ENTRY_ATTR_FIELD_SRC_IP/SAI_ACL_ENTRY_ATTR_FIELD_DST_IP enabled, and then disabling the field by setting enable=false, a match on L3_type=IPv4 will remain programmed for the rule Issue resolved after the fix
Allow the max scale of virtual routers to be configure for SPC-1, SPC-2, SPC-3 when fastboot enable
Remove default hash key of SRC_MAC, DST_MAC and ETH_TYPE

This reverts commit 02b17839c3.
Reverts #14933
The earlier commit caused a race condition that particularly broke cross branch warm upgrade.
Issue happens when db_migrator is still migrating the DB and finalizer is checking DB for list of components to reconcile.
If migration is not complete, finalizer get an empty list to wait for. Due to this, finalizer concludes warmboot (deletes system wide warmboot flag) and cause all the services to do cold restart.

* Re-add 127.0.0.1/8 when bringing down the interfaces
With #5353, 127.0.0.1/16 was added to the lo interface, and then
127.0.0.1/8 was removed. However, when bringing down the lo interface,
like during a config reload, 127.0.0.1/16 gets removed, but 127.0.0.1/8
isn't added back to the interface. This means that there's a period of
time where 127.0.0.1 is not available at all, and services that need to
connect to 127.0.01 (such as for redis DB) will fail.
To fix this, when going down, add 127.0.0.1/8. Add this address before
the existing configuration gets removed, so that 127.0.0.1 is available
at all times.
Note that running `ifdown lo` doesn't actually bring down the loopback
interface; the interface always stays "physically" up.

- Why I did it
Add Secure Boot support to SONiC OS.
Secure Boot (SB) is a verification mechanism for ensuring that code launched by a computer's UEFI firmware is trusted. It is designed to protect a system against malicious code being loaded and executed early in the boot process before the operating system has been loaded.
- How I did it
Added a signing process to sign the following components:
shim, grub, Linux kernel, and kernel modules when doing the build, and when feature is enabled in build time according to the HLD explanations (the feature is disabled by default).
- How to verify it
There are self-verifications of each boot component when building the image, in addition, there is an existing end-to-end test in sonic-mgmt repo that checks that the boot succeeds when loading a secure system (details below).
How to build a sonic image with secure boot feature: (more description in HLD)
Required to use the following build flags from rules/config:
SECURE_UPGRADE_MODE="dev"
SECURE_UPGRADE_DEV_SIGNING_KEY="/path/to/private/key.pem"
SECURE_UPGRADE_DEV_SIGNING_CERT="/path/to/cert/key.pem"
After setting those flags should build the sonic-buildimage.
Before installing the image, should prepared the setup (switch device) with the follow:
check that the device support UEFI
stored pub keys in UEFI DB
enabled Secure Boot flag in UEFI
How to run a test that verify the Secure Boot flow:
The existing test "test_upgrade_path" under "sonic-mgmt/tests/upgrade_path/test_upgrade_path", is enough to validate proper boot
You need to specify the following arguments:
Base_image_list your_secure_image
Taget_image_list your_second_secure_image
Upgrade_type cold
And run the test, basically the test will install the base image given in the parameter and then upgrade to target image by doing cold reboot and validates all the services are up and working correctly
