* [BGP]Adding configuration knob to allow advertise Loopback ipv6 /128 prefix
By default when IPv6 address is configured with /128 as subnet mask in Loopback0 interface, it will be advertised as prefix with /64 subnet.
To control this behavior a new field 'bgp_adv_lo_prefix_as_128' is introduced in DEVICE_METADATA table which when set to true will advertise prefix with /128 subnet as it is.
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.

It upgraded scapy to 2.4.5 in docker-ptf container, after this upgrade, all scripts under ansible/roles/test/files/ptftests will import scapy 2.4.5, some test cases will fail because they are not upgraded accordingly.
Reverts #10507 to avoid breaking regression test.
This reverts commit 92efc01270.
Removed python2 support for sonic-platform-daemons that was causing unit

Existing dataplane tests cannot be tested under MACsec environment due to the traffic under MACsec link is encrypted. So, I will override the dp_poll of ptf to MACsec dp_poll to decrypt the MACsec packets on injected ports (PR: Azure/sonic-mgmt#5490). MACsec decryption library depends on scapy 2.4.5.
How I did it
Upgrade scapy library to 2.4.5 by pip.

Manual test
#### 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
manual tests and running lldp tests

#### 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
is used.
Why I did it
After the Buster and Bullseye upgrade for the restapi container, processes will no longer start because supervisord is trying to call python and python2, both of which are unavailable.

# Why I did it
Reduce the disk space taken up during bootup and runtime.
# How I did it
1. Remove python package cache from the base image and from the containers.
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
Only containers which appeared to have a significant pip cache size are

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
Build a new sonic-mgmt docker image based on the changes.
Use sonic-mgmt docker container of the newly built image to run test scripts that depend on the
allure-pytest package. No ImportError is raised.
