After pinging any failed IPv6 neighbor entries, set the remaining failed/incomplete entries to a permanent INCOMPLETE state. This manual setting to INCOMPLETE prevents these entries from automatically transitioning to FAILED state, and since they are now incomplete any subsequent NA messages for these neighbors is able to resolve the entry in the cache.
Signed-off-by: Lawrence Lee <lawlee@microsoft.com>
Why I did it
The initial value has to be present for the state machines to work. In active-standby dual-tor scenario, or any hardware mux scenario, the value will be updtaed eventually with a delay.
However, in active-active dual-tor scenario, there is no other mechanism to initialize the value and get state machines started.
So this script will have to write something at start up time.
For active-active dualtor, 'active' is a more preferred initial value, the state machine will switch the state to standby soon if
link prober found link not in good state.
How I did it
Update the script to always provide initial values.
How to verify it
Tested on active-active dual-tor testbed.

Avoid write_standby in warm restart context.
sign-off: Jing Zhang zhangjing@microsoft.com
Why I did it
In warm restart context, we should avoid mux state change.
How I did it
Check warm restart flag before applying changes to app db.
How to verify it
Ran write_standby in table missing, key missing, field missing scenarios.
Did a warm restart, app db changes were skipped. Saw this in syslog:
WARNING write_standby: Taking no action due to ongoing warmrestart.
When using trap on SIGTERM the script will not react to the SIGTERM signal sent while a child is executing.
I.e, the following script does not react on SIGTERM sent to it if it is
waiting for sleep to finish:
```
trap "echo Handled SIGTERM" 0 2 3 15
echo "Before sleep"
sleep inf
echo "After sleep"
```
Instead, trap only on EXIT which covers also a scenario with exit on
SIGINT, SIGTERM.

Spanning from sonic-net/sonic-linkmgrd#76, this PR is to update warm restart finalizer to wait for linkmgrd to be reconciled.
sign-off: Jing Zhang zhangjing@microsoft.com
Why I did it
To make sure finalizer save config after linkmgrd's reconciliation.
How I did it
Add linkmgrd to the reconciliation wait list of warmboot finalizer.
How to verify it
Verified on lab device, linkmgrd reconciled as expected.

Why I did it
This PR is to backport #11569 into 202012 branch.
This PR is to apply different DSCP_TO_TC_MAP to downlink and uplink ports on T1 in dualtor deployment.
For T1 downlink ports (To T0)
The DSCP_TO_TC_MAP is not changed. DSCP2 and DSCP6 are mapped to TC2 and TC6 respectively.
For T1 uplink ports (To T1)
A new DSCP_TO_TC_MAP|AZURE_UPLINK is defined and applied. DSCP2 and DSCP6 are mapped to TC1 to avoid mixing up lossy and lossless traffic from T2.
The extra lossy PG2 and PG6 added in PR #11157 is reverted as well because no traffic from T2 is mapped to PG2 or PG6 now.
How I did it
Define a new map DSCP_TO_TC_MAP|AZURE_UPLINK for 7260 T1.
How to verify it
Verified by test case in test_j2files.py.
What I did:
Added bgp as a dependent of swss
Why I did it:
bgp container was not restarting on swss crash. When swss crashes, linkmgrd
doesn't initate a switchover because it cannot access the default route from
orchagent. Bringing down bgp with swss will isolate the ToR, causing linkmgrd
to initiate a switchover to the peer ToR avoiding significant packet loss.

Fix in Monit memory_checker plugin. Skip fetching running containers if docker engine is down (can happen in deinit).
This PR fixes issue #11472.
Signed-off-by: liora liora@nvidia.com
Why I did it
In the case where Monit runs during deinit flow, memory_checker plugin is fetching the running containers without checking if Docker service is still running. I added this check.
How I did it
Use systemctl is-active to check if Docker engine is still running.
How to verify it
Use systemctl to stop docker engine and reload Monit, no errors in log and relevant print appears in log.
Which release branch to backport (provide reason below if selected)
The fix is required in 202205 and 202012 since the PR that introduced the issue was cherry picked to those branches (#11129).
Why I did it
This PR is to cherry-pick #11448 to 202012 branch after resolving conflicts.
There are conflicts in
files/build_templates/qos_config.j2

Why I did it
Storage backend has all vlan members tagged. If untagged packets are received on those links, they are accounted as RX_DROPS which can lead to false alarms in monitoring tools. Using this acl to hide these drops.
How I did it
Created a acl template which will be loaded during minigraph load for backend. This template will allow tagged vlan packets and dropped untagged

Support to use symbol links in platform folder to reduce the image size.
The current solution is to copy each lazy installation targets (xxx.deb files) to each of the folders in the platform folder. The size will keep growing when more and more packages added in the platform folder. For cisco-8000 as an example, the size will be up to 2G, while most of them are duplicate packages in the platform folder.
How I did it
Create a new folder in platform/common, all the deb packages are copied to the folder, any other folders where use the packages are the symbol links to the common folder.
Why platform.tar?
We have implemented a patch for it, see #10775, but the problem is the the onie use really old unzip version, cannot support the symbol links.
The current solution is similar to the PR 10775, but make the platform folder into a tar package, which can be supported by onie. During the installation, the package.tar will be extracted to the original folder and removed.

Why I did it
This PR aims to fix an issue (#10088) by enhancing the script memory_checker.
Specifically, if container is not created successfully during device is booted/rebooted, then memory_checker do not need check its memory usage.
How I did it
In the script memory_checker, a function is added to get names of running containers. If the specified container name is not in current running container list, then this script will exit without checking its memory usage.
How to verify it
I tested on a lab device by following the steps:
Stops telemetry container with command sudo systemctl stop telemetry.service
Removes telemetry container with command docker rm telemetry
Checks whether the script memory_checker ran by Monit will generate the syslog message saying it will exit without checking memory usage of telemetry.
Issue fixed: when performing a warm-reboot or fast-reboot from 201811 or 201911 to 202012 the kernel command line contains duplicate information. This issue is related to a change that was made to make 202012 boot0 file more futureproof.
A cold reboot brings everything back into a clean slate though not always desirable.
Changes done:
Added some logic to properly detect the end of the Aboot cmdline when cmdline-aboot-end delimiter is not set (clean case)
Added some logic to regenerate the Aboot cmdline when cmdline-aboot-end is set but duplicate parameters exists before (dirty case). Reorganized some code to handle duplicate parameter handling in the allowlist.

Configure different DSCP_TO_TC_MAP between uplink and downlink on T1 switch in dual ToR scenario
On T1 uplink, both DSCP 2/6 will be mapped to TC 1 for the purpose of avoiding such traffic occupying lossless buffers.
On T1 downlink, they will be mapped to TC 2/6 respectively. (unchanged)
- How I did it
For vendors who want to configure different DSCP_TO_TC_MAP between uplinks and downlinks on T1, they should
Define generate_dscp_to_tc_map macro in SKU's qos.json.j2 file
Define map AZURE for downlink and AZURE_UPLINK for uplink
Define jinja2 variable different_dscp_to_tc_map as True
