What/Why I did:
Issue1: By setting up of ipvlan interface in interface-config.sh we are not tolerant to failures. Reason being interface-config.service is one-shot and do not have restart capability.
Scenario: For example if let's say database service goes in fail state then interface-services also gets failed because of dependency check but later database service gets restart but interface service will remain in stuck state and the ipvlan interface nevers get created.
Solution: Moved all the logic in database service from interface-config service which looks more align logically also since the namespace is created here and all the network setting (sysctl) are happening here.With this if database starts we recreate the interface.
Issue 2: Use of IPVLAN vs MACVLAN
Currently we are using ipvlan mode. However above failure scenario is not handle correctly by ipvlan mode. Once the ipvlan interface is created and ip address assign to it and if we restart interface-config or database (new PR) service Linux Kernel gives error "Error: Address already assigned to an ipvlan device." based on this:https://github.com/torvalds/linux/blob/master/drivers/net/ipvlan/ipvlan_main.c#L978Reason being if we do not do cleanup of ip address assignment (need to be unique for IPVLAN) it remains in Kernel Database and never goes to free pool even though namespace is deleted.
Solution: Considering this hard dependency of unique ip macvlan mode is better for us and since everything is managed by Linux Kernel and no dependency for on user configured IP address.
Issue3: Namespace database Service do not check reachability to Supervisor Redis Chassis Server.
Currently there is no explicit check as we never do Redis PING from namespace to Supervisor Redis Chassis Server. With this check it's possible we will start database and all other docker even though there is no connectivity and will hit the error/failure late in cycle
Solution: Added explicit PING from namespace that will check this reachability.
Issue 4:flushdb give exception when trying to accces Chassis Server DB over Unix Sokcet.
Solution: Handle gracefully via try..except and log the message.
Why I did it
There is a bug that the Port attributes in CONFIG_DB will be cleared if using sudo config macsec port add Ethernet0 or sudo config macsec port del Ethernet0
How I did it
To fetch the port attributes before set/remove MACsec field in port table.

Fixes#9279
- Why I did it
Part of larger effort to move all SONiC systems to bullseye
- How I did it
1. Update container makefiles with correct dependencies
2. Update container Dockerfile with correct base image
3. Update container Dockerfile with correct apt dependencies
4. Update any other makefiles with dependencies to remove python2 support
5. Minor changes to support bullseye / python3
- How to verify it
Run regression on the switch:
1. Verify PTF community tests work
2. Verify syncd runs and all ports come up / pass traffic
3. Verify all platform tests succeed
Why I did it
When lldpmgrd handled events of other tables besides PORT_TABLE, error message was printed to log.
How I did it
Handle event according to its file descriptor instead of looping all registered selectables for each coming event.
How to verify it
I verified same events are being handled by printing events key and operation, before and after the change.
Also, before the change, in init flow after config reload, when lldpmgrd handled events of other tables besides PORT_TABLE, error messages were printed to log, this issue is solved now.
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.

Why I did it
Recirc port is used to only forward traffic from one asic to another asic. So it's not required to configure LLDP on it.
How I did it
Add interface prefix helper for recirc port. Similar to skip configuring LLDP on inband port, add check in lldpmgrd to skip recirc port by checking interface prefix.
Asic PCI ID (PCI address) is collected by chassisd (inside pmon -
Azure/sonic-platform-daemons#175) and saved in CHASSIS_STATE_DB (in
redis_chassis). CHASSIS_STATE_DB is accessible by swss containers.
At docker-init.sh (script is called after swss container is created and before
anything that could run in swss like orchagent...), we wait until asic PCI ID
of the corresponding asic is populated by chassisd. We then update asic_id in
CONFIG_DB of asic's database.
A system supporting dynamic asic PCI ID identification requires to have a file
(empty) use_pci_id_chassis in its platform dir.
When orchagent runs, it has correct asic PCI ID in its CONFIG_DB.

Why I did it
This PR aims to fix the Monit issue which shows Monit can't reset its counter when monitoring memory usage of telemetry container.
Specifically the Monit configuration file related to monitoring memory usage of telemetry container is as following:
check program container_memory_telemetry with path "/usr/bin/memory_checker telemetry 419430400"
if status == 3 for 10 times within 20 cycles then exec "/usr/bin/restart_service telemetry"
If memory usage of telemetry container is larger than 400MB for 10 times within 20 cycles (minutes), then it will be restarted.
Recently we observed, after telemetry container was restarted, its memory usage continuously increased from 400MB to 11GB within 1 hour, but it was not restarted anymore during this 1 hour sliding window.
The reason is Monit can't reset its counter to count again and Monit can reset its counter if and only if the status of monitored service was changed from Status failed to Status ok. However, during this 1 hour sliding window, the status of monitored service was not changed from Status failed to Status ok.
Currently for each service monitored by Monit, there will be an entry showing the monitoring status, monitoring mode etc. For example, the following output from command sudo monit status shows the status of monitored service to monitor memory usage of telemetry:
Program 'container_memory_telemetry'
status Status ok
monitoring status Monitored
monitoring mode active
on reboot start
last exit value 0
last output -
data collected Sat, 19 Mar 2022 19:56:26
Every 1 minute, Monit will run the script to check the memory usage of telemetry and update the counter if memory usage is larger than 400MB. If Monit checked the counter and found memory usage of telemetry is larger than 400MB for 10 times
within 20 minutes, then telemetry container was restarted. Following is an example status of monitored service:
Program 'container_memory_telemetry'
status Status failed
monitoring status Monitored
monitoring mode active
on reboot start
last exit value 0
last output -
data collected Tue, 01 Feb 2022 22:52:55
After telemetry container was restarted. we found memory usage of telemetry increased rapidly from around 100MB to more than 400MB during 1 minute and status of monitored service did not have a chance to be changed from Status failed to Status ok.
How I did it
In order to provide a workaround for this issue, Monit recently introduced another syntax format repeat every <n> cycles related to exec. This new syntax format will enable Monit repeat executing the background script if the error persists for a given number of cycles.

#### Why I did it
when adding and removing ports after init stage we saw two issues:
first:
In several cases, after removing a port, lldpmgr is continuing to try to add a port to lldp with lldpcli command. the execution of this command is continuing to fail since the port is not existing anymore.
second:
after adding a port, we sometimes see this warning messgae:
"Command failed 'lldpcli configure ports Ethernet18 lldp portidsubtype local etp5b': 2021-07-27T14:16:54 [WARN/lldpctl] cannot find port Ethernet18"
we added these changes in order to solve it.
#### How I did it
port create events are taken from app db only.
lldpcli command is executed only when linux port is up.
when delete port event is received we remove this command from pending_cmds dictionary
#### How to verify it

#### Why I did it
SONiC is migrating to bullseye. This will update the sonic-pins container to bullseye.
#### How I did it
The [sonic-pins code](https://github.com/Azure/sonic-buildimage/blob/master/rules/p4rt.mk) isn't dependent on any architecture so it will already build successfully for bullseye. This PR updates the docker to use bullseye.
#### How to verify it
Today we cannot build the docker-sonic-p4rt.gz target (e.g. Issue #9885). With this change the docker will build successfully. The P4RT executable will not run, because of a missing runtime library, libgmpxx, which I'll address in a followup PR.
#### Description for the changelog
Update docker-sonic-p4rt.gz target to build with Bullseye instead of Buster.
Python 2 isn't installed by default in Buster and Bullseye containers,
and the scripts/modules can be used with Python 3, so make sure Python 3

2. During bootup, if logs are to be stored in memory, then don't create the `var-log.ext4` file just to delete it later during bootup.
3. For the partition containing `/host`, don't reserve any blocks for just the root user. This just makes sure all disk space is available for all users, if needed during upgrades (for example).
* Remove pip2 and pip3 caches from some containers

Why I did it
This fix is to address issue: Azure/sonic-mgmt#5280
In the sonic-mgmt Dockerfile, python package allure-pytest is installed after ENV USER $user.
Consequently the package is installed to path /home/$user/.local and is only available to the $user
account. If we use root account in sonic-mgmt docker container to run tests, any script importing
the allure package will fail with ImportError. We need to install the allure-pytest package to global
directory instead of user local directory.
How I did it
Update the sonic-mgmt Dockerfile to ensure that the allure-pytest package is installed to global directory
How to verify it

- Why I did it
Error log was shown on switches during boot
pmon#supervisord 2021-12-22 04:27:16,709 INFO exited: chassis_db_init (exit status 0; not expected)

Add exit code zero as an expected exit code and also disable autorestart.
- How to verify it
Boot the switch and ensure the above log line does not appear.
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.

Why I did it
Arista 7060 platform has a rare and unreproduceable PCIe timeout that could possibly be solved with increasing the switch PCIe timeout value. To do this we'll call a script for this platform to increase the PCIe timeout on boot-up.
No issues would be expected from the setpci command. From the PCIe spec:
"Software is permitted to change the value in this field at any
time. For Requests already pending when the Completion
Timeout Value is changed, hardware is permitted to use either
the new or the old value for the outstanding Requests, and is
permitted to base the start time for each Request either on when
this value was changed or on when each request was issued. "
How I did it
Add "platform-init" support in swss docker similar to how "hwsku-init" is called, only this would be for any device belonging to a platform. Then the script would reside in device data folder.
Additionally, add pciutils dependency to docker-orchagent so it can run the setpci commands.
How to verify it
On bootup of an Arista 7060, can execute:
lspci -vv -s 01:00.0 | grep -i "devctl2"
In order to check that the timeout has changed.
- Create a script in the orchagent docker container which listens for these encapsulated packets which are trapped to CPU (indicating that they cannot be routed/no neighbor info exists for the inner packet). When such a packet is received, the script will issue a ping command to the packet's inner destination IP to start the neighbor learning process.
- This script is also resilient to portchannel status changes (i.e. interface going up or down). An interface going down does not affect traffic sniffing on interfaces which are still up. When an interface comes back up, we restart the sniffer to start capturing traffic on that interface again.
Why I did it
To enable test support for BFD-related features, the PTF docker needs to have the proper support for BFD. This PR aims to add BFD support in ptf docker.
How I did it
Clone and build OpenBFDD for PTF docker.
How to verify it
Build locally and verify BFD is supported.
What I did:
Updated Jinja Template to enable BGP Graceful Restart based on device role. By default it will be enable only if the device role type is TorRouter.
Why I did:-
By default FRR is configured in Graceful Helper mode. Graceful Restart is needed on T0/TorRouter only since the device can go for warm-reboot. For T1/LeafRouter it need to be in Helper mode only
- Add INCLUDE_PINS to config to enable/disable container
- Add Docker files and supporting resources
- Add sonic-pins submodule and associated make files

#### 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.
#### Which release branch to backport (provide reason below if selected)
None
#### Description for the changelog
Build P4RT container for PINS
Updated BGP Template for the case:
1. For Packet Chassis do not advertise Loopback4096 address into BGP as there is Static Route for same.
Having this route in BGP causes two level of recursion in Zebra and cause assert in Zebra
when there are many nexthop involved
2. Advertise only P2P Connected IP's into BGP (External Peers). For Packet chassis we have backend IP Interface subnet and if
they get advertised into BGP then it also causes recursion
The BGP_VOQ_CHASSIS_NEIGHBOR keepalive and holdtime timers are
configured similar to general neighbors. Changes are done to configure
BGP_VOQ_CHASSIS_NEIGHBOR timers similar to BGP_INTENAL_NEIGBOR since voq
chassis bgp neighbors are similar to bgp internal neighbors in
multi-asic. As it is done for bgp internal neighbors, the keepalive and
holdtime timers are set to 3 and 10 seconds respectively. Also similar
to bgp internal neighbors, connection retry timer is also configured for
voq chassis bgp neighbors.

Fixes#9376
Because /etc/passwd and /etc/group have been overwritten with symlinks
to /host_etc/passwd and /host_etc/group, the debug container build
fails. This is because the debug container is built without /etc being
mounted at /host_etc in the container (which does happen at runtime).
Because of that, /etc/passwd and /etc/group don't exist, which causes
some package installation errors when openssh-client tries to create a
group.
This is a partial revert of 1347f29178.

- Why I did it
This is to update the common sonic-buildimage infra for reclaiming buffer.
- How I did it
Render zero_profiles.j2 to zero_profiles.json for vendors that support reclaiming buffer
The zero profiles will be referenced in PR [Reclaim buffer] Reclaim unused buffers by applying zero buffer profiles #8768 on Mellanox platforms and there will be test cases to verify the behavior there.
Rendering is done here for passing azure pipeline.

* [ACL] enable ACL FC when genereting config from minigraph but disable by default
Why I did it
To support ACL counters on Flex Counter Infrastructure.
How I did it
Enable ACL FC in init_cfg and minigraph. Disable when genereting configuration from preset.
How to verify it
Together with depends PRs. Run ACL/Everflow test suite.

Why I did it
During swss container startup, if ndppd starts up before/with vlanmgrd, ndppd will be pinned at nearly 100% CPU usage.
How I did it
Only start ndppd after vlanmgrd is running. Also, call ndppd directly instead of through bash for improved logging and to prevent orphaned processes.

#### Why I did it
Nokia IXR7250E platform requires grpcio, grpcio-tools python library, and libprotobuf-dev, libgrpc++ library
#### How I did it
Modified the build_debian.sh install libprotobuf-dev and libgrpc++ to support nokia ndk
Modified the sonic_debian_extension.j2 to install the grpcio and grpcio-tools in the host
Modified the docker-platform-monitor/Dockerfile.js to install grpcio and grpcio-tools for the pmon container.
#### How to verify it
Image running success.
Why I did it
"chassis_db_init" task of PMON should be skipped on Mellanox simx platform, since the hardware info which this task is trying to access is not available on simx platforms, It will introduce some error log.
How I did it
Add the capability for "chassis_db_init" in the template for it can be skipped by adding configuration in "pmon_daemon_control.json".
add "skip_chassis_db_init" configuration for simx platforms.
use symbol link for "pmon_daemon_control.json" since all the simx platforms share the same configuration
How to verify it
Build an image and install it on simx platform to check whether "chassis_db_init" task is skipped.

Fix the check used to wait for interfaces to come up. The group name in
the supervisor config files has changed from isc-dhcp-relay to
dhcp-relay.
Also, in the wait script, wait 10 additional seconds after the vlans,
port channels, and any interfaces are up. This is because dhcrelay
listens on all interfaces (in addition to port channels and vlans), and
to ensure that it stays in a clean state during runtime, wait some extra
time to make sure that those interfaces are created as well.

Linkmgrd monitors link status, mux status, and link state. Has
the link becomes unhealthy, linkmgrd will trigger mux switchover
on a standby ToR ensuring uninterrupted service to servers/blades.
This PR is initial implementation of linkmgrd.
Also, docker-mux container hold packages related to maintaining and managing
mux cable. It currently runs linkmgrd binary that monitor and switches
the mux if needed.
This PR also introduces mux-container and starts linkmgrd as startup when
build is configured with INCLUDE_MUX=y
Edit: linkmgrd PR will follow.
