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.

* [y_cable] Support for initialization of new Daemon ycable to support
ycables
This PR also adds the commit in sonic-platform-daemons
94fa239 [y_cable] refactor y_cable to a seperate logic and new daemon from xcvrd (#219)
Why I did it
This PR separates the logic of Y-Cable from xcvrd. Before this change we were utilizing xcvrd daemon to control all aspects of Y-Cable right from initialization to processing requests from other entities like orch,linkmgr.
Now we would have another daemon ycabled which will serve this purpose.
Logically everything still remains the same from the perspective of other daemons.
it also take care aspects like init/delete daemon from Y-Cable perspective.
How I did it
To serve the purpose we build a new wheel sonic_ycabled-1.0-py3-none-any.whl and install it inside pmon.
We also initalize the daemon ycabled which serves our purpose for refactor inside pmon

#### Why I did it

snmpd writes the below error message in syslog :
snmp#snmpd[27]: truncating integer value > 32 bits
This message is written in syslog when the hrSystemUptime(1.3.6.1.2.1.25.1.1.0 / system uptime) or sysUpTime(1.3.6.1.2.1.1.3 network management portion or snmpd uptime) is queried when either of these counters overflow beyond 32 bit value. This happens the device uptime or snmpd uptime is more than 497 days.
#### How I did it
Reference: https://access.redhat.com/solutions/367093 and https://linux.die.net/man/1/snmpcmd
To avoid seeing this message if the counter grows, the snmpd error log level is changed to display LOG_EMERG, LOG_ALERT, LOG_CRIT, and LOG_DEBUG.
Without this change, LOG_ERR and LOG_WARNING would also be logged in syslog.
#### How to verify it
On a device which is up for more than 497 days, modify supervisord.conf with the change and restart snmp.
Query 1.3.6.1.2.1.1.3 and verify that log message is not seen.

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

#### 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.

Support to build armhf/arm64 platforms on arm based system without qemu simulator.
When building the armhf/arm64 on arm based system, it is not necessary to use qemu simulator.
How I did it
Build armhf on armhf system, or build arm64 on arm64 system, by default, qemu simulator will not be used.
When building armhf on arm64, and you have enabled armhf docker, then it will build images without simulator automatically. It is based how the docker service is run.
Docker base image change:
For amd64, change from debian:to amd64/debian:
For arm64, change from multiarch/debian-debootstrap:arm64- to arm64v8/debian:
For armhf, change from multiarch/debian-debootstrap:armhf- to arm32v7/debian:
See https://github.com/docker-library/official-images#architectures-other-than-amd64
The mapping relations:
arm32v6 --- armel
arm32v7 --- armhf
arm64v8 --- arm64
Docker image armhf deprecated info: https://hub.docker.com/r/armhf/debian, using arm32v7 instead.
For multiasic, the back end asics use ip addresss of Loopback4096 for BGP router id. In VOQ multi-asic chassis there are no back end asics. All the asics are front end and the iBGP connections are established via Ethernet-IB of asics. Since these asics are not designated as BackEnd, the ip address of interface Loopback0 is used as BGP router id. Since the ip address of Loopback0 is same for all the asics in the line card, same router id is used for voq iBGP configurations and hence the iBGP connections are not established. Changes are done to fix this
Why I did it
There are scenarios that End-of-RIB comes from a part of the peers arrives after reconciliation. In such scenarios, if the route selection deferral timer has the default value of 360 seconds, FRR would not set up routes and all routes would be removed after reconciliation. This PR reduces the route selection deferral timer so that at least routes to parts of the peers get restored at the point of reconciliation.
Fix#7488
How I did it
Reduce route selection deferral timer for bgp graceful restart to 15 seconds.
Why I did it
the motivation for this PR is to add retry_call to several test cases in the community, for example, the following cases:
test_show_platform_fanstatus_mocked
test_show_platform_temperature_mocked
are executing a command once and comparing the output to the expected mock data,
sometimes differences between the mock and the actual are causing the tests to fail.
retry will make these tests more stable.
retry will also be more efficient than sleep which will cause the tests to run longer because sometimes it is not necessary to sleep all that time, retry will only run a function only until it passed.
