[Monit] Restart telemetry container if memory usage is beyond the threshold (#7645)
Signed-off-by: Yong Zhao yozhao@microsoft.com

Why I did it
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.

Remove 'vm.panic_on_oom=1' (#7678)
#### 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 '

[ntp] Fix ntp.conf template to allow setting of source port in CONFIG_DB (#7586)
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.

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

[systemd] disable default systemd udev rules for interfaces (#7369)
Fix #7364

99-default.link - was always in SONiC, but previous systemd (<247) had an issue and it did not work due to issue systemd/systemd#3374. Now systemd 247 works.

However, such policy overrides teamd provided mac address which causes teamd netdev to use a random mac
address. Therefore, needs to be disabled.

[chassis] Add templates and code to support VoQ chassis iBGP peers (#5622)
This commit has following changes:

* Add templates and code to support VoQ chassis iBGP peers

* Add support to convert a new VoQChassisInternal element in the
   BGPSession element of the minigraph to a new BGP_VOQ_CHASSIS_NEIGHBOR 
   table in CONFIG_DB.
* Add a new set of "voq_chassis" templates to docker-fpm-frr
* Add a new BGP peer manager to bgpcfgd to add neighbors from the
  BGP_VOQ_CHASSIS_NEIGHBOR table using the voq_chassis templates.
* Add a test case for minigraph.py, making sure the VoQChassisInternal
  element creates a BGP_VOQ_CHASSIS_NEIGHBOR entry, but not if its
  value is "false".
* Add a set of test cases for the new voq_chassis templates in
  sonic-bgpcfgd tests.

Note that the templates expect the new
"bgp bestpath peer-type multipath-relax" bgpd configuration to be
available.

Copy dummy flannel.conf to get around absence of CNI Network (#6985)
Why I did it
We skip install of CNI plugin, as we don't need. But this leaves node in "not ready" state, upon joining master.
To fix, we copy this dummy .conf file in /etc/cni/net.d

How I did it
Keep this file in /usr/share/sonic/templates and copy to /etc/cni/net.d upon joining k8s master.

How to verify it
Upon configuring master-IP and enable join, watch node join and move to ready state.

[Supervisord] Deduplicate the alerting messages of critical processes from Supervisord. (#6849)
Signed-off-by: Yong Zhao yozhao@microsoft.com

Why I did it
In the configuration of rsyslog, duplicate messages will be suppressed and reported in the format of message repeated n times.
Due to this behavior, if a critical process in a container exited unexpectedly, the alerting message will be written into syslog once
and not be written into syslog anymore until the second critical process exited. This PR aims to differentiate these alerting messages such that they will not be suppressed by rsyslogd and can appear in the syslog periodically.

How I did it
This PR adds a counter into the alerting message and shows how many minutes a critical process was not running.

How to verify it
I verified and test this implementation on a physical DUT.

[multi-asic][vs]: Update topology script to retrieve hwsku from minigraph (#6219)
Update topology script to retrieve hwsku from minigraph
if hwsku information is not available in config_db.
Fix clean up of interfaces in msft_multi_asic_vs hwsku
topology script.
- Why I did it
When bringing up multi-asic VS switch, topology service is started during boot up.
Topology service starts a shell script which runs the topology script present in /usr/share/sonic/device// directory. To invoke hwsku specific script, the topology script tries to retrieve hwsku information from config_db.
During initial boot up config_db might not be populated. In order to start topology service before config_db is updated,
update topology script to get hwsku information from minigraph.xml if it is available.
This will be helpful to bring up multi-asic VS testbed by loading minigraph and starting topology service.
- How I did it
Update topology.sh script to retrieve hwsku information from minigraph.xml.
Fix clean up function on msft_multi_asic_vs toplogy script.
- How to verify it
single-asic VS - no change; topology service is only enabled for multi-asic VS.
multi-asic VS - Bring up multi-asic VS image, copy minigraph to vs image, start topology service. Topology service should be successful.
to test clean up function fix, start topology service - make sure interfaces are created and moved to the right namespaces.
stop topology service - make sure namespace do not have any interface and all front end interfaces are present in default namespace.

[sonic-host-service] Move to sonic-host-services package (#6273)
- Why I did it

To move ‘sonic-host-service’ which is currently built as a separate package to ‘sonic-host-services' package. 

- How I did it

- Moved 'sonic-host-server' to 'src/sonic-host-services' and included it as part of the python3 wheel.
- Other files were moved to 'src/sonic-host-services-data' and included as part of the deb package.
- Changed build option ‘INCLUDE_HOST_SERVICE’ to ‘ENABLE_HOST_SERVICE_ON_START’ for enabling sonic-hostservice at boot-up by default.

[multi_asic][vs]: Add dependency in teamd service to start after topology service(#6594)
[multi_asic][vs]: Add dependency in teamd service to start after topology service.
- Why I did it
In multi-asic VS, topology service is run after database service to set up the internal asic topology.
swss and syncd have a dependency to start after topology service is run so that the interfaces are moved to right namespace and created in the right namespace. In case of multi-asic vs, during the initial boot up, when there is no configuration added, teamd service starts and swss/syncd do not start as topology service does not start. Upon loading configuration using config_db or minigraph, swss and sycnd start up , but teamd is not restarted as swss is not stopped and started. This causes teamd to be in a bad state and requires a reload of config.

- How I did it
Add dependency in teamd service to start after topology service is completed.

- How to verify it
No change in single asic vs or platform.
No change in multi-asic regular image.
Change only in multi-asic VS. Bring up a multi-asic VS image without any configration, teamd service will fail to start due to dependency failure. Load minigraph, start topology service, load configuration, ensure all services come up.

[pcie-check] Update underlying pcieutil command and add to sudoers file (#6682)
- Why I did it

As of Azure/sonic-utilities#1297, subcommands of pcieutil have changed to remove the redundant pcie- prefix. This PR adapts calling applications (pcie-check) to the new syntax.

Resolves #6676

- How I did it

Remove pcie- prefix from pcieutil subcommands in calling applications
Also add pcieutil * to sudoers file, as pcieutil requires elevated permissions

[kdump] Fix OOM events in crashkernel (#6447)
A few issues where discovered with crashkernel on Arista platforms.

1) platforms using `docker_inram=on` would end up OOM in kdump environment.
This happens because the same initramfs is used by SONiC and the crashkernel.
With `docker_inram=on` the `dockerfs.tar.gz` is extracted in a `tmpfs` created for the occasion.
Since `dockerfs.tar.gz` weights more than 1.5G, it doesn't fit into the kdump environment and ends up OOM.
This OOM event can in turn trigger a panic.

2) Arista platforms with `secureboot` enabled would fail to load the crashkernel because the kernel parameter would be discarded on boot.
This happens because the `boot0` in secureboot mode is strict about kernel parameter injection.

3) The secureboot path allowlist would remove kernel crash reports.

4) The kdump service would fail on Arista products since `/boot/` is empty in `secureboot`

**- How I did it**

1) To prevent an OOM event in the crashkernel the fix is to avoid the codepaths in `union-mount` that create tmpfs and populate them. Some more codepath specific to Arista devices are also skipped to make the kdump process faster.
This relies on detecting that the initramfs is starting in a kdump environment and skipping some initialization.
The `/usr/sbin/kdump-config` tool appends a few kernel cmdline arguments when loading the crashkernel.
The most unique one is `systemd.unit=kdump-tools.service` which is used in a few initramfs hooks to set `in_kdump`.

2) To allow `kdump` to work in `secureboot` environment the cmdline generation in boot0 was slightly modified.
The codepath to load kernel parameters changed by SONiC is now running for booting in secure mode.
It was altered to prevent an append only behavior which would grow the `kernel-cmdline` at every reboot.
This ever growing behavior would lead `kexec` to fail to load the kernel due to a too long cmdline.

3) To get the kernel crash under /var/crash this path has to be added to `allowlist_paths`

4) The `/host/image-XXX/boot` folder is now populated in `secureboot` mode but not used.

**- How to verify it**

Regular boot:
 - enable kdump
 - enable docker_inram=on via kernel-params
 - reboot
 - generate a crash `echo c > /proc/sysrq-trigger`
 - before: witness OOM events on the console
 - after: crash kernel works and crash available under /var/crash

Secure boot:
 - enable kdump
 - reboot
 - generate a crash `echo c > /proc/sysrq-trigger`
 - before: witness no kdump
 - after: crash kernel works and crash available under /var/crash

[baseimage]: add docker ps to the sudoer file (#6604)
fixes Azure/sonic-utilities#1389

With the recent changes in sudoer files. The  show commands fails for the read-only users. 
The problem here is the 'docker ps' is failing in the function [get_routing_stack()](8a1109ed30/show/main.py (L54)) therefore all the CLI commands are failing.

[multi asic] add ip netns identify command to sudoer (#6591)
Signed-off-by: Arvindsrinivasan Lakshmi Narasimhan <arlakshm@microsoft.com>

- Why I did it
The command sudo ip netns identify <pid> is used in function get_current_namespace
to check in the cli command is running in host context or within a namespace.

This function is used for every CLI command and command sudo ip netns identify <pid> needs to be added in sudoer files to allow users with RO access to run show cli commands

This problem is not there on single asic platforms.

- How I did it
Add ip netns identify [0-9]* to sudoers file.
