- 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
fixesAzure/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.

- 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.

**- Why I did it**
This PR aims to monitor the running status of each container. Currently the auto-restart feature was enabled. If a critical process exited unexpected, the container will be restarted. If the container was restarted 3 times during 20 minutes, then it will not run anymore unless we cleared the flag using the command `sudo systemctl reset-failed <container_name>` manually.
**- How I did it**
We will employ Monit to monitor a script. This script will generate the expected running container list and compare it with the current running containers. If there are containers which were expected to run but were not running, then an alerting message will be written into syslog.
**- How to verify it**
I tested this feature on a lab device `str-a7050-acs-3` which has single ASIC and `str2-n3164-acs-3` which has a Multi-ASIC. First I manually stopped a container by running the command `sudo systemctl stop <container_name>`, then I checked whether there was an alerting message in the syslog.

In scenario where upgrade gets config from minigraph, it could miss tacacs credentials as they are not in minigraph. Hence restore explicitly upon load-minigraph, if present.
- Why I did it
Upon boot, when config migration is required, the switch could load config from minigraph. The config-load from minigraph would wipe off TACACS key and disable login via TACACS, which would disable all remote user access. This change, would re-configure the TACACS if there is a saved copy available.
- How I did it
When config is loaded from minigraph, look for a TACACS credentials back up (tacacs.json) under /etc/sonic/old_config. If present, load the credentials into running config, before config-save is called.
- How to verify it
Remove /etc/sonic/config_db.json and do an image update. Upon reboot, w/o this change, you would not be able ssh in as remote user. You may login as admin and check out, "show tacacs" & "show aaa" to verify that tacacs-key is missing and login is not enabled for tacacs.
With this change applied, remove /etc/sonic/config_db.json, but save tacacs & aaa credentials as tacacs.json in /etc/sonic/. Upon reboot, you should see remote user access possible.
Added source interface support for NTP.
Also made NTP start on Mgmt-VRF by default when configured.

2) The ntp script updated to by default start on Mgmt-VFT when configured.

There is a issue for counters after warm-reboot:
If I clear counters by command "sonic-clear counters", then execute 'warm-reboot' and whenSONiC is restart, the counters showed with command "show interface counters" is still old counters before "sonic-clear". It is not the right counters because the counters file in '/tmp' is lost in warm-reboot process.
- How I did it
I fixed it by saving '/tmp/portstat-0' folders in '/host/' before executing 'warm-reboot' (in pull request Azure/sonic-utilities#1099 ), and restore the counters folders back to '/tmp/' after warm-reboot process is finished.
- How to verify it
Clear counters by command 'sonic-clear'

Execute 'warm-reboot'
Use command ‘show interface counters’ to see if the counters is right.

When eth0 IP address is configured, an ip rule is getting added for eth0 IP address through the interfaces.j2 template.
This eth0 ip rule creates an issue when VRF (data VRF or management VRF) is also created in the system.
When any VRF (data VRF or management VRF) is created, a new rule is getting added automatically by kernel as "1000: from all lookup [l3mdev-table]".
This l3mdev IP rule is never getting deleted even if VRF is deleted.
Once if this l3mdev IP rule is added, if user configures IP address for the eth0 interface, interfaces.j2 adds an eth0 IP rule as "1000:from 100.104.47.74 lookup default ". Priority 1000 is automatically chosen by kernel and hence this rule gets higher priority than the already existing rule "1001:from all lookup local ".
This results in an issue "ping from console to eth0 IP does not work once if VRF is created" as explained in Issue 551.
More details and possible solutions are explained as comments in the Issue551.
This PR is to resolve the issue by always fixing the low priority 32765 for the IP rule that is created for the eth0 IP address.
Tested with various combinations of VRF creation, deletion and IP address configuration along with ping from console to eth0 IP address.

Do a load after after updating all feature states.
- How to verify it
Not a easy one
Have a script that

sleep 2s
run redis-cli/config command to update AAA/TACACS table
Run the script above and watch the file /etc/pam.d/common-auth-sonic for a minute.

**- Why I did it**
If we ran the CLI commands `sudo config feature autorestart snmp disabled/enabled` or `sudo config feature autorestart swss disabled/enabled`, then SNMP container will be stopped and started. This behavior was not expected since we updated the `auto_restart` field not update `state` field in `FEATURE` table. The reason behind this issue is that either `state` field or `auto_restart` field was updated, the function `update_feature_state(...)` will be invoked which then starts snmp.timer service.
The snmp.timer service will first stop snmp.service and later start snmp.service.
In order to solve this issue, the function `update_feature_state(...)` will be only invoked if `state` field in `FEATURE` table was
updated.
**- How I did it**
When the demon `hostcfgd` was activated, all the values of `state` field in `FEATURE` table of each container will be
cached. Each time the function `feature_state_handler(...)` is invoked, it will determine whether the `state` field of a
container was changed or not. If it was changed, function `update_feature_state(...)` will be invoked and the cached
value will also be updated. Otherwise, nothing will be done.
**- How to verify it**
We can run the CLI commands `sudo config feature autorestart snmp disabled/enabled` or `sudo config feature autorestart swss disabled/enabled` to check whether SNMP container is stopped and started. We also can run the CLI commands `sudo config feature state snmp disabled/enabled` or `sudo config feature state swss disabled/enabled` to check whether the container is stopped and restarted.

**- Why I did it**
To introduce dynamic support of BBR functionality into bgpcfgd.
BBR is adding `neighbor PEER_GROUP allowas-in 1' for all BGP peer-groups which points to T0
Now we can add and remove this configuration based on CONFIG_DB entry
**- How I did it**
I introduced a new CONFIG_DB entry:
- table name: "BGP_BBR"
- key value: "all". Currently only "all" is supported, which means that all peer-groups which points to T0s will be updated
- data value: a dictionary: {"status": "status_value"}, where status_value could be either "enabled" or "disabled"
Initially, when bgpcfgd starts, it reads initial BBR status values from the [constants.yml](https://github.com/Azure/sonic-buildimage/pull/5626/files#diff-e6f2fe13a6c276dc2f3b27a5bef79886f9c103194be4fcb28ce57375edf2c23cR34). Then you can control BBR status by changing "BGP_BBR" table in the CONFIG_DB (see examples below).
bgpcfgd knows what peer-groups to change fron [constants.yml](https://github.com/Azure/sonic-buildimage/pull/5626/files#diff-e6f2fe13a6c276dc2f3b27a5bef79886f9c103194be4fcb28ce57375edf2c23cR39). The dictionary contains peer-group names as keys, and a list of address-families as values. So when bgpcfgd got a request to change the BBR state, it changes the state only for peer-groups listed in the constants.yml dictionary (and only for address families from the peer-group value).
**- How to verify it**
Initially, when we start SONiC FRR has BBR enabled for PEER_V4 and PEER_V6:
```
admin@str-s6100-acs-1:~$ vtysh -c 'show run' | egrep 'PEER_V.? allowas'
neighbor PEER_V4 allowas-in 1
neighbor PEER_V6 allowas-in 1
```
Then we apply following configuration to the db:
```
admin@str-s6100-acs-1:~$ cat disable.json
{
"BGP_BBR": {
"all": {
"status": "disabled"
}
}
}
admin@str-s6100-acs-1:~$ sonic-cfggen -j disable.json -w
```
The log output are:
```

```
Check FRR configuraiton and see that no allowas parameters are there:
```
admin@str-s6100-acs-1:~$ vtysh -c 'show run' | egrep 'PEER_V.? allowas'
admin@str-s6100-acs-1:~$
```
Then we apply enabling configuration back:
```
admin@str-s6100-acs-1:~$ cat enable.json
{
"BGP_BBR": {
"all": {
"status": "enabled"
}
}
}
admin@str-s6100-acs-1:~$ sonic-cfggen -j enable.json -w
```
The log output:
```

Check FRR configuraiton and see that the BBR configuration is back:

There is currently a bug where messages from swss with priority lower than the current log level are still being counted against the syslog rate limiting threshhold. This leads to rate-limiting in syslog when the rate-limiting conditions have not been met, which causes several sonic-mgmt tests to fail since they are dependent on LogAnalyzer. It also omits potentially useful information from the syslog. Only rate-limiting messages of level INFO and lower allows these tests to pass successfully.

**- Why I did it**
I was asked to change "Allow list" prefix-list generation rule.
Previously we generated the rules using following method:
```
For each {prefix}/{masklen} we would generate the prefix-rule
permit {prefix}/{masklen} ge {masklen}+1
Example:
Prefix 1.2.3.4/24 would have following prefix-list entry generated
permit 1.2.3.4/24 ge 23
```
But we discovered the old rule doesn't work for all cases we have.
So we introduced the new rule:
```
For ipv4 entry,
For mask < 32 , we will add ‘le 32’ to cover all prefix masks to be sent by T0
For mask =32 , we will not add any ‘le mask’
For ipv6 entry, we will add le 128 to cover all the prefix mask to be sent by T0
For mask < 128 , we will add ‘le 128’ to cover all prefix masks to be sent by T0
For mask = 128 , we will not add any ‘le mask’
```
**- How I did it**
I change prefix-list entry generation function. Also I introduced a test for the changed function.
**- How to verify it**
1. Build an image and put it on your dut.
2. Create a file test_schema.conf with the test configuration
```
{
"BGP_ALLOWED_PREFIXES": {
"DEPLOYMENT_ID|0|1010:1010": {
"prefixes_v4": [
"10.20.0.0/16",
"10.50.1.0/29"
],
"prefixes_v6": [
"fc01:10::/64",
"fc02:20::/64"
]
},
"DEPLOYMENT_ID|0": {
"prefixes_v4": [
"10.20.0.0/16",
"10.50.1.0/29"
],
"prefixes_v6": [
"fc01:10::/64",
"fc02:20::/64"
]
}
}
}
```
3. Apply the configuration by command
```
sonic-cfggen -j test_schema.conf --write-to-db
```
4. Check that your bgp configuration has following prefix-list entries:
```
admin@str-s6100-acs-1:~$ show runningconfiguration bgp | grep PL_ALLOW

When a large number of changes occur to the ACL table of Config DB, caclmgrd will get flooded with notifications, and previously, it would regenerate and apply the iptables rules for each change, which is unnecessary, as the iptables rules should only get applied once after the last change notification is received. If the ACL table contains a large number of control plane ACL rules, this could cause a large delay in caclmgrd getting the rules applied.
This patch causes caclmgrd to delay updating the iptables rules until it has not received a change notification for at least 0.5 seconds.
bring up chassisdb service on sonic switch according to the design in
Distributed Forwarding in VoQ Arch HLD
Signed-off-by: Honggang Xu <hxu@arista.com>
**- Why I did it**
To bring up new ChassisDB service in sonic as designed in ['Distributed forwarding in a VOQ architecture HLD' ](90c1289eaf/doc/chassis/architecture.md).
**- How I did it**
Implement the section 2.3.1 Global DB Organization of the VOQ architecture HLD.
**- How to verify it**
ChassisDB service won't start without chassisdb.conf file on the existing platforms.
ChassisDB service is accessible with global.conf file in the distributed arichitecture.
