- 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.

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

[Build]: Fix hundreds of thousands lines of logs printed in marvell-armhf
It is caused by the bad format of the marvell sai package mrvllibsai_armhf_1.7.1-6.deb, increasing the waiting time to reduce the logs, and reduce the waste of the CPU.
Implement infrastructure that allows enabling address sanitizer
for docker containers. Enable address sanitizer for SWSS container.
- Why I did it
To add a possibility to compile SONiC applications with address sanitizer (ASAN).
ASAN is a memory error detector for C/C++. It finds:
1. Use after free (dangling pointer dereference)
2. Heap buffer overflow
3. Stack buffer overflow
4. Global buffer overflow
5. Use after return
6. Use after the scope
7. Initialization order bugs
8. Memory leaks
- How I did it
By adding new ENABLE_ASAN configuration option.
- How to verify it
By default ASAN is disabled and the SONiC image is not affected.
When ASAN is enabled it inspects all allocation, deallocation, and memory usage that the application does in run time. To verify whether the application has memory errors tests that trigger memory usage of the application should be run. Ideally, the whole regression tests should be run. Memory leaks reports will be placed in /var/log/asan/ directory of SONiC host OS.

* [arm64]: Fix registration of the qemu interpreters
The current code doesn't properly run the container that registers the
qemu interpreters. It checks to see if the container is "known" by
Docker, but that doesn't indicate whether it's been run or not.
Therefore, just always register the qemu interpreters in the kernel, to
make sure the binary that's in the slave images that we build is used.
* [build]: Reduce the number of python calls
Modify the BLDENV and PROJECT_ROOT variables in slave.mk to be
immediate execution instead of lazy execution. Neither of these
variables should be changing for the duration of the build in each slave
container, so just run it once instead of every time they're referenced.
When running `make configure` for broadcom arm64 (where all of the slave
images are already built) on an amd64 host, this reduces the time spent
in each slave container from 4.5-5 minutes to 2 minutes.

#### Why I did it
Adds P4RT container to SONiC for PINS
The P4RT app is covered by this HLD:
https://github.com/pins/SONiC/blob/master/doc/pins/p4rt_app_hld.md
#### How I did it
Followed the pattern and templates used for other SONiC applications
#### How to verify it
Build SONiC with INCLUDE_P4RT set to "y".
Verify that the resulting build has a container called "p4rt" running.
You can verify that the service is up by running the following command on the SONiC switch:
```bash
sudo netstat -lpnt | grep p4rt
```
You should see the service listening on TCP port 9559.

To be able to generate multi-asic KVM image.
To provide flexibility to generate single asic or both single and multi-asic images.
How I did it
Add a new build param, BUILD_MULTIASIC_KVM, if set to "y", the multi-asic VS target KVM images will be generated. If not, only single asic VS image will be generated.
Make changes to build_image.sh to generate 4-asic and 6-asic KVM images if BUILD_MULTIASIC_KVM parameter is set to y
How to verify it
Generate single-asic VS as currently done, no change in build steps:
make configure PLATFORM=vs
make target/sonic-vs.img.gz - will generate only single asic KVM image.
make BUILD_MULTIASIC_KVM=y target/sonic-vs.img.gz - will generate single asic and multi-asic KVM images.
should generate:
sonic-vs.bin
sonic-vs.img.gz
sonic-4asic-vs.img.gz
sonic-6asic-vs.img.gz
With a Bullseye base image, and PTF being based on Stretch, if there are
autogenerated files that are reused from the Bullseye build for Stretch,
then autoconf-based packages will fail. This is because the default set
of CFLAGS that dpkg passes in includes `-ffile-prefix-map=`, which is
not a supported flag with the GCC in Stretch. Then, when running `make
clean` in a Stretch environment, make will try to regenerate the
autoconf-based files with the cached set of CFLAGS from Bullseye. This
causes an error, since that flag is unknown.
To work around this, after each build, clean up all built objects and
autogenerated files. This makes sure that it is cleaned up in the same
environment as the build environment.
Note that this issue affects just autoconf packages. For apps using just
regular Makefiles, they will probably be fine (they'll still be cleaned
up as well).

#### Why I did it
Provide possibility to specify curl options as the present curl support provided in Azure/sonic does not extend capability for options like --user which some of the cisco artifacts are requiring.
#### How I did it
Add extensions to the slave.mk file to include curl options as follows:
$($*_CURL_OPTIONS)
#### How to verify it
Option 1) use curl -u, and environment variables
it with --user <user:password> curl_options. Ex: --user foo:'bar!'
curl -u ${BASIC_AUTH_HEADER} https://foo.bar
This works to obscure password/credential in a terminal session that someone else might see directly or via screen share.
Option 2) Option 1: use curl -n
If you run linux, create a ~/.netrc file and insert your creds there, and use curl -n.
chmod the file to 400. curl knows how to extract your creds from the file silently. You never have to type creds on the command line again.
If you run Windows, and use curl, you must name the file _netrc . As on *nix, the file should be in your home directory, and should have appropriate permissions.
For Administrative APIs , my .netrc file looks like this:
machine foobar-linux
login foo
password bar
