How I did it
Removed the timers and delayed target since the delayed services would start based on event driven approach.
Cleared port table during config reload and cold reboot scenario.
Modified yang model, init_cfg.json to change has_timer to delayed
How to verify it
Added UT to verify
Depends on https://github.com/sonic-net/sonic-linux-kernel/pull/315
#### Why I did it
The name SECURE_UPGRADE_DEV_SIGNING_CERT is misleading, this flag is relevant to both to dev and prod signing.
#### How I did it
Rename all mentions of name SECURE_UPGRADE_DEV_SIGNING_CERT to SECURE_UPGRADE_SIGNING_CERT - this is also done with PR in sonic-linux-kernel repository
#### How to verify it
Build SONiC using your own prod script
- Why I did it
Fix issue with signing tool not running due to being call with the path from the host and not the path it is mounted on inside the docker-slave
- How I did it
Modified the path on the SECURE_UPGRADE_PROD_SIGNING_TOOL flag to the path where it is mounted inside the slave docker
- How to verify it
Build SONiC using your own prod script
- 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

Why I did it
Cherry-pick #14601, for code conflict.
Support to add SONiC OS Version in device info.
It will be used to display the version info in the SONiC command "show version". The version is used to do the FIPS certification. We do not do the FIPS certification on a specific release, but on the SONiC OS Version.
SONiC Software Version: SONiC.master-13812.218661-7d94c0c28
SONiC OS Version: 11
Distribution: Debian 11.6
Kernel: 5.10.0-18-2-amd64

How I did it
How to verify it
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'.
Slave.mk in the host, it extracts the cache contents from the log and stores them
in the cache folder. Cache contents are encoded as base64 format for
easy passing.

If make fails, we can't rerun the make process, because existing patches can't apply again.
How I did it
Check if patches are applied. if yes, don't apply patches again.
How to verify it
- Why I did it
This optimization is needed for DPU SONiC. DPU SONiC runs a limited set of containers and teamd and radv containers are not part of them. Unlike the other containers, there was no possibility to disable teamd and radv containers compilation.
To reduce DPU SONiC compilation time and reduce the image size this commit adds the possibility to disable their compilation.
- How I did it
Two new configuration options are added to rules/config file:
INCLUDE_TEAMD
INCLUDE_ROUTER_ADVERTISER
By default to preserve the existing behavior both options are enabled. There are two ways to override them:
To change option value to "n" in rules/config file.
To override their value using SONIC_OVERRIDE_BUILD_VARS env variable:
SONIC_OVERRIDE_BUILD_VARS="SONIC_INCLUDE_TEAMD=y SONIC_INCLUDE_ROUTER_ADVERTISER=n"
- How to verify it
The default behavior is preserved. To verify it compile the image without overriding new options. Install the image and verify that both teamd and radv containers are present and running.
To verify the new options override them with "n" value. Compile and install image. Verify that no docker containers are present. Verify that SWSS can start without errors.
Why I did it
Cherry pick from #13097
[Build] Support Debian snapshot mirror to improve build stability
It is to enhance the reproducible build, supports the Debian snapshot mirror. It guarantees all the docker images using the same Debian mirror snapshot and fixes the temporary build failure which is caused by remote Debain mirror indexes changed during the build. It is also to fix the version conflict issue caused by no fixed versions of some of the Debian packages.
How I did it
Add a new feature to support the Debian snapshot mirror.
How to verify it
Why I did it
In PR check pipelines, there are too many duplicated warnings:
fatal: No names found, cannot describe anything.
SONIC_IMAGE_VERSION will not change in one build. We don't need to calculate in every reference. We just need calculate one time, then record it.
In Makefile, '=' will calculate again and again when it is referred.
How I did it
Fix it in Makefile.
How to verify it
Check this PR's check pipeline result.
Why I did it
It is to fix the broadcom build failure, it is caused by the build image docker-dhcp-relay:latest not found.

How I did it
When the feature SONIC_CONFIG_USE_NATIVE_DOCKERD_FOR_BUILD not enabled, always save as the latest tag, not use the specify version.
The version is dynamic, it is changed when a new commit checked in, but the image of docker-dhcp-relay is not necessary to change.
PR #12829 modified the docker tagging scheme such that optional docker
containers would be tagged with the SONiC image version. However, the
docker-image-load macro wasn't updated for these changes. Update it
here.

Fixes: #11521
- Why I did it
When build SONiC dockers, SONiC build system tags all of them with latest tag. This is Ok for all built-in dockers because we will also tag them with image version tag in sonic_debian_extension.j2 script. On the other hand, some of these dockers are SONiC packages and they are installed by sonic-package-manager which creates a only one tag whcih is recorded in the corresponding .gz file. This leads to having these dockers tagged only with latest tag. This change saves the tag as an image version string in .gz file, so that these dockers have version identification in their tag.
- How I did it
I modified slave.mk to save the version tag instead of latest tag.
- How to verify it
I verified this change by running show version

Why I did it
[Build] Fix the docker-sync not found issue
How I did it
When SONIC_CONFIG_USE_NATIVE_DOCKERD_FOR_BUILD not enabled, not to remove the docker-sync tag.
#### Why I did it
Currently at the Azure build system, the P4RT container is disabled by default at the build time. Here the goal is to include the P4RT container at the build time while disabling it at the runtime. The user can enable/disable the p4rt app through the config based on the preference.
#### How I did it
Changed the config in rules/config and init-cfg.json.j2
Why I did it
Add the original docker tag without username to support some of the docker file not changed build broken issue.
The username suffix only required when the native build feature enabled, but if not enabled, the docker file not necessary to change, the build should be succeeded.
It is to support cisco 202205 build.

Why I did it
Replace configuration parameter for gnmi write, and we will add other gnmi write features in the future.
How I did it
Update rules/config and other Makefile.
How to verify it
Build sonic image.
With this PR in, you flap BGP and use events_tool to see the published events.
With telemetry PR #111 in and corresponding submodule update done in buildimage, one could run gnmi_cli to capture BGP flap events.
The current error handling code for when a deb package fails to be
installed currently has a chain of commands linked together by && and
ends with `exit 1`. The assumption is that the commands would succeed,
and the last `exit 1` would end it with a non-zero return code, thus
fully failing the target and causing the build to stop because of bash's
-e flag.
However, if one of the commands prior to `exit 1` returns a non-zero
return code, then bash won't actually treat it as a terminating error.
From bash's man page:
```
-e Exit immediately if a pipeline (which may consist of a single simple
command), a list, or a compound command (see SHELL GRAMMAR above),
exits with a non-zero status. The shell does not exit if the
command that fails is part of the command list immediately
following a while or until keyword, part of the test following the
if or elif reserved words, part of any command executed in a && or
|| list except the command following the final && or ||, any
command in a pipeline but the last, or if the command's return
value is being inverted with !. If a compound command other than a
subshell returns a non-zero status because a command failed while
-e was being ignored, the shell does not exit.
```
The part `part of any command executed in a && or || list except the
command following the final && or ||` says that if the failing command
is not the `exit 1` that we have at the end, then bash doesn't treat it
as an error and exit immediately. Additionally, since this is a compound
command, but isn't in a subshell (subshell are marked by `(` and `)`,
whereas `{` and `}` just tells bash to run the commands in the current
environment), bash doesn't exist. The result of this is that in the
deb-install target, if a package installation fails, it may be
infinitely stuck in that while-loop.
There are two fixes for this: change to using a subshell, or use `;`
instead of `&&`. Using a subshell would, I think, require exporting any
shell variables used in the subshell, so I chose to change the `&&` to
`;`. In addition, at the start of the subshell, `set +e` is added in,
which removes the exit-on-error handling of bash. This makes sure that
all commands are run (the output of which may help for debugging) and
that it still exits with 1, which will then fully fail the target.

* Ported Marvell armhf build on x86 for debian buster to use cross-compilation instead of qemu emulation
Current armhf Sonic build on amd64 host uses qemu emulation. Due to the
nature of the emulation it takes a very long time, about 22-24 hours to
complete the build. The change I did to reduce the building time by
porting Sonic armhf build on amd64 host for Marvell platform for debian
buster to use cross-compilation on arm64 host for armhf target. The
overall Sonic armhf building time using cross-compilation reduced to
about 6 hours.

Refactors the SONiC Installer to support greater flexibility in building for a given architecture and bootloader.
#### Why I did it
Currently the SONiC installer assumes that if a platform is ARM based that it uses the `uboot` bootloader and uses the `grub` bootloader otherwise. This is not a correct assumption to make as ARM is not strictly tied to uboot and x86 is not strictly tied to grub.
#### How I did it
To implement this I introduce the following changes:
* Remove the different arch folders from the `installer/` directory
* Merge the generic components of the ARM and x86 installer into `installer/installer.sh`
* Refactor x86 + grub specific functions into `installer/default_platform.conf`
* Modify installer to call `default_platform.conf` file and also call `platform/[platform]/patform.conf` file as well to override as needed
* Update references to the installer in the `build_image.sh` script
* Add `TARGET_BOOTLOADER` variable that is by default `uboot` for ARM devices and `grub` for x86 unless overridden in `platform/[platform]/rules.mk`
* Update bootloader logic in `build_debian.sh` to be based on `TARGET_BOOTLOADER` instead of `TARGET_ARCH` and to reference the grub package in a generic manner
#### How to verify it
This has been tested on a ARM test platform as well as on Mellanox amd64 switches as well to ensure there was no impact.
#### Description for the changelog
[arm] Refactor installer and build to allow arm builds targeted at grub platforms

- Why I did it
Profiling the system state on init after fast-reboot during create_switch function execution, it is possible to see few python scripts running at the same time.
This parallel execution consume CPU time and the duration of create_switch is longer than it should be.
Following this finding, and the motivation to ensure these services will not interfere in the future, LLDP is delayed in 90 seconds until the system finish the init flow after fastboot.
- How I did it
Add a timer for LLDP service.
Copy the timer file to the host bin image.
- How to verify it
Run fast-reboot on MLNX platform and observe faster create_switch execution time.
This PR is dependent on PR: #10567
Currently, the build dockers are created as a user dockers(docker-base-stretch-<user>, etc) that are
specific to each user. But the sonic dockers (docker-database, docker-swss, etc) are
created with a fixed docker name and common to all the users.
docker-database:latest
docker-swss:latest
When multiple builds are triggered on the same build server that creates parallel building issue because
all the build jobs are trying to create the same docker with latest tag.
This happens only when sonic dockers are built using native host dockerd for sonic docker image creation.
This patch creates all sonic dockers as user sonic dockers and then, while
saving and loading the user sonic dockers, it rename the user sonic
dockers into correct sonic dockers with tag as latest.
docker-database:latest <== SAVE/LOAD ==> docker-database-<user>:tag
The user sonic docker names are derived from 'DOCKER_USERNAME and DOCKER_USERTAG' make env
variable and using Jinja template, it replaces the FROM docker name with correct user sonic docker name for
loading and saving the docker image.
* [build]: Patch debootstrap to not unmount the host's /proc filesystem
Currently, when the final image is being built (sonic-vs.img.gz,
sonic-broadcom.bin, or similar), each invocation of sudo in the
build_debian.sh script takes 0.8 seconds to run and execute the actual
command. This is because the /proc filesystem in the slave container has
been unmounted somehow. This is happening when debootstrap is running,
and it incorrectly unmounts the host's (in our case, the slave
container's) /proc filesystem because in the new image being built,
/proc is a symlink to the host's (the slave container's) /proc. Because
of that, /proc is gone, and each invocation of sudo adds 0.8 seconds
overhead. As a side effect, docker exec into the slave container during
this time will fail, because /proc/self/fd doesn't exist anymore, and
docker exec assumes that that exists.
Debootstrap has fixed this in 1.0.124 and newer, so backport the patch
that fixes this into the version that Bullseye has.

* [build_debian.sh]: Use eatmydata to speed up deb package installations
During package installations, dpkg calls fsync multiples times (for each
package) to ensure that tht efiles are written to disk, so that if
there's some system crash during package installation, then it is in at
least a somewhat recoverable state. For our use case though, we're
installing packages in a chroot in fsroot-* from a slave container and
then packaging it into an image. If there were a system crash (or even
if docker crashed), the fsroot-* directory would first be removed, and
the process would get restarted. This means that the fsync calls aren't
really needed for our use case.
The eatmydata package includes a library that will block/suppress the
use of fsync (and similar) system calls from applications and will
instead just return success, so that the application is not blocked on
disk writes, which can instead happen in the background instead as
necessary. If dpkg is run with this library, then the fsync calls that
it does will have no effect.
Therefore, install the eatmydata package at the beginning of
build_debian.sh and have dpkg be run under eatmydata for almost all
package installations/removals. At the end of the installation, remove
it, so that the final image uses dpkg as normal.
In my testing, this saves about 2-3 minutes from the image build time.

Why I did it
To sign SONiC kernel image and allow secure boot based system to verify SONiC image before loading into the system.
How I did it
Pass following parameter to rules/config.user
Ex:
SONIC_ENABLE_SECUREBOOT_SIGNATURE := y
SIGNING_KEY := /path/to/key/private.key
SIGNING_CERT := /path/to/public/public.cert
How to verify it
Secure boot enabled system enrolled with right public key of the, image in the platform UEFI database will able to verify image before load.
Alternatively one can verify with offline sbsign tool as below.
export SBSIGN_KEY=/abc/bcd/xyz/
sbverify --cert $SBSIGN_KEY/public_cert.cert fsroot-platform-XYZ/boot/vmlinuz-5.10.0-8-2-amd64 mage
O/P:
Signature verification OK
