b5bf5e3bce [interfaces] Reduce Calls to SONiC Cfggen (#5174)
Calls to sonic-cfggen is CPU expensive. This PR reduces calls to
sonic-cfggen to one call during startup when running interfaces-
config.

fae4c4bfcc [swss] Enhance ARP Update to Call Sonic Cfggen Once (#5398)
This PR limited the number of calls to sonic-cfggen to one call
per iteration instead of current 3 calls per iteration.

The PR also installs jq on host for future scripts if needed.

[aboot]: Better handle tmpfs management in boot0 (#6268)
To limit IO and space usage on the flash device the boot0 script makes sure the SWI is in memory.
Because SONiC maps /tmp on the flash, some logic is required to make sure of it.
However it is possible for some provisioning mechanism to already download the swi in a memory file system.
This was not properly handled by the boot0 script.
It now properly detect if the image is on a tmpfs or a ramfs and keep it there if that is the case.

- How I did it

Check the filesystem on which the SWI pointed by swipath lies.
If this filesystem is a ramfs or a tmpfs the move_swi_to_tmpfs becomes a no-op.
Made sure the cleanup logic would not behave unexpectedly.

- How to verify it

In SONiC:

Download the swi under /tmp and makes sure it gets moved to /tmp/tmp-swi which gets mounted for that purpose.
Make sure /tmp/tmp-swi gets unmounted once the install process is done.

Create a new mountpoint under /ram using either ramfs or tmpfs and download the swi there.
Install the swi using sonic-installer and makes sure the image doesn't get moved by looking at the logs.

[201911][hostcfgd]:wait updating the feature table till system init is done (#6234)
- Why I did it
The change is done to make sure the system initialization is done before the hostcfgd sets the feature states.

- How I did it
This is port of the PR #6232.
Since the systemctl version in 201911 doesn't support "--wait".
Added a function to check the output of systemctl is-system-running every second, till the command system is done booting up.

For now this change is only applicable to multi asic platforms based on the testing this change will be extended to all platforms in the future PR.

dae5c4c930 [build_templates]: Start SNMP timer after SWSS service (#6195)
Fixes #5663

- Why I did it
It's currently possible for the SNMP timer to conflict with config reload (specifically if the timer triggers while config reload is stopping the SWSS service). config reload triggers SWSS to shutdown, which causes SNMP to shutdown, which conflicts with the SNMP timer causing SNMP to startup. See the linked issue for more details.

- How I did it
Including the After ordering dependency forces the SNMP timer to wait until SWSS finishes stopping, preventing the conflict. If there is an ordering dependency between two units (e.g. one unit is ordered After another), if one unit is shutting down while the other is starting up, the shutdown will always be ordered before the startup. In this case, that means that the SNMP timer is forced to wait for the SWSS shutdown to complete. Only then can the SNMP timer proceed. See here for more details.

It's important to note that the After dependency will not cause SWSS to be started when the SNMP timer fires (assuming that SWSS has not yet been started). The existing Requisite dependency in the SNMP service will also not cause SWSS to be started, instead it will cause the SNMP service to fail if SWSS is not active.

1d1898d8e2 Enhanced Feature table to support 'always_enabled' value for state and auto-restart fields. (#6000)
Added new flag value 'always_enabled' for the state and auto-restart field of feature table

init_cfg.json is updated to initialize state field of database/swss/syncd/teamd feature and auto-restart field of database feature
as always_enabled

Once the state/auto-restart value is initialized as "always_enabled" it is immutable and cannot be change via feature config commands. (config feature..) PR#Azure/sonic-utilities#1271

hostcfgd will not take any action if state field value is 'always_enabled'

Since we have always_enabled field for auto-restart updated supervisor-proc-exit-listener
not to have special check for database and always rely on value from Feature table.

339d2aa6c8 [mgmt ip]: mvrf ip rule priority change to 32765 (#5754)
Fix Azure/SONiC#551

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.

ecd10b9d10 Load config after subscribe (#5740)
- Why I did it
The update_all_feature_states can run in the range of 20+ seconds to one minute. With load of AAA & Tacacs preceding it, any DB updates in AAA/TACACS during the long running feature updates would get missed. To avoid, switch the order.

- How I did it
Do a load after after updating all feature states.

- How to verify it
Not a easy one
Have a script that
restart hostcfgd
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.

- When it repro:
The updates will not reflect in /etc/pam.d/common-auth-sonic

2eec3b3254 [bgpcfgd]: Dynamic BBR support (#5626)
**- 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:
```
Oct 14 18:40:22.450322 str-s6100-acs-1 DEBUG bgp#bgpcfgd: Received message : '('all', 'SET', (('status', 'disabled'),))'

```

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:
```
Oct 14 18:40:41.074720 str-s6100-acs-1 DEBUG bgp#bgpcfgd: Received message : '('all', 'SET', (('status', 'enabled'),))'

```


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

bee6c87f90 [bgpcfgd]: Change prefix-list generation for "Allow prefix" feature (#5639)
**- 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:
```

7a015eacc1 Fix 'NoSuchProcess' exception in process_checker (#5716)
The psutil library used in process_checker create a cache for each
process when calling process_iter. So, there is some possibility that
one process exists when calling process_iter, but not exists when
calling cmdline, which will raise a NoSuchProcess exception. This commit
fix the issue.

963bd7fdc4 [docker-teamd]: Add teamd as a depedent service to swss (#5628)
**- Why I did it**
On teamd docker restart, the swss and syncd needs to be restarted as there are dependent resources present.

**- How I did it**
Add the teamd as a dependent service for swss
Updated the docker-wait script to handle service and dependent services separately.
Handle the case of warm-restart for the dependent service

**- How to verify it**

Verified the following scenario's with the following testbed
VM1 ----------------------------[DUT 6100] -----------------------VM2,  ping traffic continuous between VMs

1. Stop teamd docker alone
      >  swss, syncd dockers seen going away
      >  The LAG reference count error messages seen for a while till swss docker stops.
      >  Dockers back up.

2. Enable WR mode for teamd. Stop teamd docker alone
      >  swss, syncd dockers not removed.
      >  The LAG reference count error messages not seen
      >  Repeated stop teamd docker test - same result, no effect on swss/syncd.

3. Stop swss docker.
      >  swss, teamd, syncd goes off - dockers comes back correctly, interfaces up

4. Enable WR mode for swss . Stop swss docker
      >  swss goes off not affecting syncd/teamd dockers.

5. Config reload
      > no reference counter error seen, dockers comes back correctly, with interfaces up

6. Warm reboot, observations below
	 > swss docker goes off first
	 > teamd + syncd goes off to the end of WR process.
 	 > dockers comes back up fine.
	 > ping traffic between VM's was NOT HIT

7. Fast reboot, observations below
	 > teamd goes off first ( **confirmed swss don't exit here** )
	 > swss goes off next
	 > syncd goes away at the end of the FR process
	 > dockers comes back up fine.
	 > there is a traffic HIT as per fast-reboot

8. Verified in multi-asic platform, the tests above other than WR/FB scenarios

d8ae2a0019 [hostcfgd] Enable/disable the container service only when the feature state was changed. (#5689)
**- 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.

4dde7d00cf [caclmgrd] Prevent unnecessary iptables updates (#5312)
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.

* [Multi-Asic] Forward SNMP requests destined to loopback IP, and coming in through the front panel interface
             present in the network namespace, to SNMP agent running in the linux host.

* Updates based on comments

* Further updates in docker_image_ctl.j2 and caclmgrd

* Change the variable for net config file.

* Updated the comments in the code.

* No need to clean up the exising NAT rules if present, which could be created by some other process.

* Delete our rule first and add it back, to take care of caclmgrd restart.
Another benefit is that we delete only our rules, rather than earlier approach of "iptables -F" which cleans up all rules.

* Keeping the original logic to clean the NAT entries, to revist when NAT feature added in namespace.

* Missing updates to log_info call.
