Enable fib_multipath_use_neigh for v4
https://www.kernel.org/doc/Documentation/networking/ip-sysctl.txt
Why I did:
This is helpful if the neighbor are not directly connected then Kernel forward to unreachable neighbor option. With this option forwarding using neighbor state to be valid.
#### Why I did it
Use a predefined variable to get vendor information when the swss docker container is created
#### How I did it
Use `{{ sonic_asic_platform }}` instead of `$SONIC_CFGGEN -y /etc/sonic/sonic_version.yml -v asic_type`
#### How to verify it
Manually test.
Master/202012 image size grew quite a bit. 3.7G harddrive can no longer hold one image and safely upgrade to another image. Every bit of harddrive space is precious to save now.
Also sh syntax seemingly changed, [ condition ] && action was a legit syntax in 201911 branch but it is an error when condition not met with 202012 or later images. Change the syntax to if statement to avoid the issue.

Fix#7968
Issue is detected on SONiC.20201231.11
In test_static_route.py::test_static_route_ecmp static routes are configured, but neighbors are not resolved after config reload even after 10 minutes.
It looks like the arp_update script is starting to ping when Vlan1000 is not fully configured.
When issue is reproduced, stuck ping6 process is observed in swss container :
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 180 0.1 0.0 6296 1272 pts/0 S 17:03 0:03 ping6 -I Vlan1000 -n -q -i 0 -c 1 -W 0 ff02::1
And when arp_update script successfully resolves neighbors, we observe sleep 300 instead of ping process
#### Why I did it
* `arp_update` fails to ping those neighbors over vlan sub interfaces.
#### How I did it
* modify `arp_update_vars.j2` to get vlan sub interfaces with ipv6 addresses assigned.
* modify `arp_update` to send ipv6 pings over those retrieved vlan sub interfaces.

#### Why I did it
I made this change to support warm/fast reboot for SONiC extension packages as per HLD Azure/SONiC#682.
#### How I did it
I extended manifest.json.j2 with new warm/fast reboot related fields and also extended sonic_debian_extension.j2 script template to generate the shutdown order files for warm and fast reboot.

Make DHCP relay docker an extension. DHCP relay now carries dhcp relay commands CLI plugin and has a complete manifest.
It is installed as extension if INCLUDE_DHCP_REALY is set to y.
DEPENDS on #5939
- How I did it
Modify DHCP relay docker makefile and dockerfile. Make changes to sonic_debian_extension.j2 to install sonic packages.
I moved DHCP related CLI tests from sonic-utilities to DHCP relay docker.
This PR introduces a way to write a plugin as part of docker image and run the tests from cli-plugin-tests directory under docker directory.

Changes to allow starting per asic services like swss and syncd only if the platform vendor codedetects the asic is detected and notified. The systemd services ordering we want is database->database@->pmon->swss@->syncd@->teamd@->lldp@
There is also a requirement that management, telemetry, snmp dockers can start even if all asic services are not up.
Why I did it
For VOQ chassis, the fabric cards will have 1-N asics. Also, there could be multiple removable fabric cards. On the supervisor, swss and syncd containers need to be started only if the fabric-card is in Online state and respective asics are detected by the kernel. Using systemd, the dependent services can be in inactive state.
How I did it
Introduce a mechanism where all ASIC dependent service wait on its state to be published via PMON to REDIS. Once the subscription is received, the service proceeds to create respective dockers.
For fixed platforms, systemd is unchanged i.e. the service bring up and docker creation happens in the start()/ExecStartPre routine of the .sh scripts.
For VOQ chassis platform on supervisor, the service bringup skips docker creation in the start() routine, but does it in the wait()/ExecStart routine of the .sh scrips.
Management dockers are decoupled from ASIC docker creation.
- Why I did it
Currently dhcp packets are disabled by the COPP manager for non ToRRouter type switches.
Even if the feature is enabled, DHCP packets wont hook to the CPU since the COPP manager will not trap this packets.
This change is to disable dhcp_relay by default for non ToRRouter switches from init_cfg.json.
With this approach, if the user want to enable the feature for non ToRRouter switches, manual enablement is required by the 'feature' configuration.
This is to keep the current approach for MSFT production issue with dhcp relay for non ToRRouter switched and allow the user to decide if to use it or not.
- How I did it
Configure dhcp_relay 'disabled' by default on init_cfg.json for non ToRRouter switches.
Remove the exclusion of dhcp packets on copp_cfg.json
- How to verify it
Enable dhcp_relay feature on a non ToRRouter switch.
Unit-tests modified so the default values on mocked CONFIG DB in 'test_vectors.py' for dhcp_relay will be 'disabled'.
This is by the change for 'init_cfg.json.j2'.
For ToRRouter the state will change from 'disabled' to 'enabled'.
Another test case added for a 'ToR' switch type, this is to test the state is 'enabled' if the user configured it to be so.
After https://github.com/Azure/sonic-buildimage/pull/7598 the packages.json generation is broken. This change fixes it make the whole build fail in case generation failed.

The voq system lag id boundary is set in redis-chassis. Changes include
setting this from database-chassis container. This fixes a timing issue
in finding datbase_config.json file from redis directory which is
created from database container. Since database container usually
starts after database-chassis container the existence of this file is
unreliable while running the command. Running the command under
database-chassis container makes sure that the database_config.json form
redis-chassis directory is guaranteed to be available and hence fixes the
timing issue.

How to verify it
Together with #6531
Before this change, a process running inside every SONiC container dealt with FEATURE table 'auto_restart' field and depending on the value decided whether a container has to be killed or not.
If killed service auto restart mechanism restarts the container.
This change moves the logic from container to the host daemon - hostcfgd.
The 'auto_restart' handling is kept in supervisor-proc-exit-listener but now it is not required for container that wants to support auto restart feature.
hostcfgd refactoring - move feature handling in another class.
override systemd service Restart= setting from hostcfgd.

#### Why I did it
- To build flashrom properly with dependency tracking.
#### How I did it
- Moved flashrom code from platform/broadcom/sonic-platform-modules-dell/tools directory to src/flashrom directory.
- At the end, flashrom_0.9.7_amd64.deb package is build which will be installed in the devices.
- Currently flashrom builds only for Dell S6100 platforms.
Introduce new sonic-buildimage images for Broadcom DNX ASIC family.
sonic-broadcom-dnx.bin
sonic-aboot-broadcom-dnx.swi
How I did it
NO CHANGE to existing make commands
make init; make configure PLATFORM=broadcom; make target/sonic-aboot-broadcom.swi; make target/sonic-broadcom.bin
The difference now is that it will result in new broadcom images for DNX asic family as well.
sonic-broadcom.bin, sonic-broadcom-dnx.bin
sonic-aboot-broadcom.swi, sonic-aboot-broadcom-dnx.swi
Note: This PR also adds support for Broadcom SAI 5.0 (based on 1.8 SAI ) for DNX based platform + changes in platform x86_64-arista_7280cr3_32p4 bcm config files and platform_env.conf files
#### Why I did it
Following the discussion in another PR https://github.com/Azure/sonic-buildimage/pull/7708#discussion_r642933510 , since there will be multi subfolders under **/var/log/mellanox**, so we agreed to only mount this folder and the subfolders will be created afterward on demand.
#### How I did it
during the syncd docker creation, only mount folder **/var/log/mellanox**
#### How to verify it
build an Mellanox image and verify the related folder on the host and docker side.
#### Why I did it
Create a target for delayed service timers. Few services in sonic have delayed to speed up the bring up of the system and essential services. However there is no way to track when they start. This will be a problem when executing config reload as config reload expects all services to be up. Hence grouped all the timers that trigger the delayed services under one target so that they could be tracked in 'config reload' command
#### How I did it
Created delay.target service and add created dependency on the delayed targets.
Why I did it
Support multiple pcie configuration file and change the pcie status table name
This is to match with below two PRs.
Azure/sonic-platform-common#195Azure/sonic-platform-daemons#189
How I did it
Check pcie configuration file with wild card and change the device status table name
How to verify it
Restart with changes and see if the pcie check works as expected.
Why I did it
The SONiC switches get their docker images from local repo, populated during install with container images pre-built into SONiC FW. With the introduction of kubernetes, new docker images available in remote repo could be deployed. This requires dockerd to be able to pull images from remote repo.
Depending on the Switch network domain & config, it may or may not be able to reach the remote repo. In the case where remote repo is unreachable, we could potentially make Kubernetes server to also act as http-proxy.
How I did it
When admin explicitly enables, the kubernetes-server could be configured as docker-proxy. But any update to docker-proxy has to be via service-conf file environment variable, implying a "service restart docker" is required. But restart of dockerd is vey expensive, as it would restarts all dockers, including database docker.
To avoid dockerd restart, pre-configure an http_proxy using an unused IP. When k8s server is enabled to act as http-proxy, an IP table entry would be created to direct all traffic to the configured-unused-proxy-ip to the kubernetes-master IP. This way any update to Kubernetes master config would be just manipulating IPTables, which will be transparent to all modules, until dockerd needs to download from remote repo.
How to verify it
Configure a switch such that image repo is unreachable
Pre-configure dockerd with http_proxy.conf using an unused IP (e.g. 172.16.1.1)
Update ctrmgrd.service to invoke ctrmgrd.py with "-p" option.
Configure a k8s server, and deploy an image for feature with set_owner="kube"
Check if switch could successfully download the image or not.

Why I did it
Currently we leveraged the Supervisor to monitor the running status of critical processes in each container and it is more reliable and flexible than doing the monitoring by Monit. So we removed the functionality of monitoring the critical processes by Monit.
How I did it
I removed the script process_checker and corresponding Monit configuration entries of critical processes.
How to verify it
I verified this on the device str-7260cx3-acs-1.
Why I did it
In upgrade scenarios, where config_db.json is not carry forwarded to new image, it could be left w/o TACACS credentials.
Added a service to trigger 5 minutes after boot and restore TACACS, if /etc/sonic/old_config/tacacs.json is present.
How I did it
By adding a service, that would fire 5 mins after boot.
This service apply tacacs if available.
How to verify it
Upgrade and watch status of tacacs.timer & tacacs.service
You may create /etc/sonic/old_config/tacacs.json, with updated credentials
(before 5mins after boot) and see that appears in config & persisted too.

This PR aims to monitor the memory usage of streaming telemetry container and restart streaming telemetry container if memory usage is larger than the pre-defined threshold.
How I did it
I borrowed the system tool Monit to run a script memory_checker which will periodically check the memory usage of streaming telemetry container. If the memory usage of telemetry container is larger than the pre-defined threshold for 10 times during 20 cycles, then an alerting message will be written into syslog and at the same time Monit will run the script restart_service to restart the streaming telemetry container.
How to verify it
I verified this implementation on device str-7260cx3-acs-1.
- Why I did it
To give SONiC Application Extension developers an environment to run and develop their apps.

#### Why I did it
If a process limits using nodes by mempolicy/cpusets, and those nodes become memory exhaustion status, one process may be killed by oom-killer.
No panic occurs in this case, because other node's memory may be free.
This means system total status may be not fatal yet.
#### How I did it
Remove 'vm.panic_on_oom=1' kernel flag from 'vmcore-sysctl.conf '
Why I did it
Currently, there is a bug in the ntp.conf jinja2 template where it will ignore the src_intf directive in CONFIG_DB if there are multiple IP addresses associated with an interface. This code change fixes that bug and allows the template to select the correct source interface for NTP.
How I did it
I did this by modifying the macro in ntp.conf.j2 which determines if there is an ip address associated with an interface to set a state variable when it detects a valid interface entry in CONFIG_DB instead of outputting "true" directly (which could result in multiple "trues" outputted for interfaces with multiple valid IP addresses).
How to verify it
Add two ipv4 addresses to an interface in SONiC
Add the following configuration to config_db.json
{
"NTP": {
"global": {
"src_intf": "Ethernet1"
}
}
}
Replace Ethernet1 with the interface name of the one you assigned the IP addresses to.
Run sudo config reload -y
Open /etc/ntp.conf and verify that the following line exists
...
interface listen Ethernet1
...
The interface specified should be the one set in the previous steps.
Description for the changelog
[ntp] Fix ntp.conf template to allow setting of source port in CONFIG_DB

Why I did it
start pcie-check.service after config-setup.service since pcie_util depends on device_info which is available with config db metadata.
How I did it
Add config-setup.service as a dependency of pcie-check.service
How to verify it
Upon reboot, check if the pcie-check.sh throws the platform api error which is dependent on DEVICE_METADATA
Why I did it
Finding running containers through "docker ps" breaks when kubernetes deploys container, as the names are mangled.
How I did it

How to verify it
Deploy a feature via kubernetes and don't expect error from container_check.
