#### 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
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"

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.

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.

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.
- What I did
All SWSS dependent services should stop before SWSS service to avoid future possible issues.
For example 'teamd' service will stop before to allow the driver unload netdev gracefully.
This is to stop all LAG's before restarting syncd service when running 'config reload' command.
- How I did it
Change the order of dependent services of SWSS.
- How to verify it
Run 'config reload' command.

[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.

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

Initially, we used Monit to monitor critical processes in each container. If one of critical processes was not running
or crashed due to some reasons, then Monit will write an alerting message into syslog periodically. If we add a new process
in a container, the corresponding Monti configuration file will also need to update. It is a little hard for maintenance.
Currently we employed event listener of Supervisod to do this monitoring. Since processes in each container are managed by
Supervisord, we can only focus on the logic of monitoring.
- How I did it
We borrowed the event listener of Supervisord to monitor critical processes in containers. The event listener will take
following steps if it was notified one of critical processes exited unexpectedly:
The event listener will first check whether the auto-restart mechanism was enabled for this container or not. If auto-restart mechanism was enabled, event listener will kill the Supervisord process, which should cause the container to exit and subsequently get restarted.
If auto-restart mechanism was not enabled for this contianer, the event listener will enter a loop which will first sleep 1 minute and then check whether the process is running. If yes, the event listener exits. If no, an alerting message will be written into syslog.
- How to verify it
First, we need checked whether the auto-restart mechanism of a container was enabled or not by running the command show feature status. If enabled, one critical process should be selected and killed manually, then we need check whether the container will be restarted or not.
Second, we can disable the auto-restart mechanism if it was enabled at step 1 by running the commnad sudo config feature autorestart <container_name> disabled. Then one critical process should be selected and killed. After that, we will see the alerting message which will appear in the syslog every 1 minute.

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.

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 case was not handled properly by the boot0 script.
It now detect if the image is on a tmpfs or a ramfs and keep it there if that is the case.
The cleanup method has been updated accordingly and will only cleanup
the mount path if it's below /tmp/ as to not affect user mounted paths.
- 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.

* First cut image update for kubernetes support.
With this,
1) dockers dhcp_relay, lldp, pmon, radv, snmp, telemetry are enabled
for kube management
init_cfg.json configure set_owner as kube for these
2) Each docker's start.sh updated to call container_startup.py to register going up
As part of this call, it registers the current owner as local/kube and its version
The images are built with its version ingrained into image during build
3) Update all docker's bash script to call 'container start/stop/wait' instead of 'docker start/stop/wait'.
For all locally managed containers, it calls docker commands, hence no change for locally managed.
4) Introduced a new ctrmgrd service, that helps with transition between owners as kube & local and carry over any labels update from STATE-DB to API server
5) hostcfgd updated to handle owner change
6) Reboot scripts are updatd to tag kube running images as local, so upon reboot they run the same image.
7) Added kube_commands.py to handle all updates with Kubernetes API serrver -- dedicated for k8s interaction only.
Added source interface support for NTP.
Also made NTP start on Mgmt-VRF by default when configured.
**- How I did it**
1) Updated hostcfg to listen to global config NTP and NTP_SERVER tables and restart ntp when ever the configuration changes. NTP table includes source interface configuration.
2) The ntp script updated to by default start on Mgmt-VFT when configured.

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.

**- How I did it**
1. Introduce field `buffer_model` in `DEVICE_METADATA|localhost` to represent which buffer model is running in the system currently:
- `dynamic` for the dynamic buffer calculation model
- `traditional` for the traditional model in which the `pg_profile_lookup.ini` is used
2. Add the tables required for the feature:
- ASIC_TABLE in platform/\<vendor\>/asic_table.j2
- PERIPHERAL_TABLE in platform/\<vendor\>/peripheral_table.j2
- PORT_PERIPHERAL_TABLE on a per-platform basis in device/\<vendor\>/\<platform\>/port_peripheral_config.j2 for each platform with gearbox installed.
- DEFAULT_LOSSLESS_BUFFER_PARAMETER and LOSSLESS_TRAFFIC_PATTERN in files/build_templates/buffers_config.j2
- Add lossless PGs (3-4) for each port in files/build_templates/buffers_config.j2
3. Copy the newly introduced j2 files into the image and rendering them when the system starts
4. Update the CLI options for buffermgrd so that it can start with dynamic mode
5. Fetches the ASIC vendor name in orchagent:
- fetch the vendor name when creates the docker and pass it as a docker environment variable
- `buffermgrd` can use this passed-in variable
6. Clear buffer related tables from STATE_DB when swss docker starts
7. Update the src/sonic-config-engine/tests/sample_output/buffers-dell6100.json according to the buffer_config.j2

We were building a custom version of Supervisor because I had added patches to prevent hangs and crashes if the system clock ever rolled backward. Those changes were merged into the upstream Supervisor repo as of version 3.4.0 (http://supervisord.org/changes.html#id9), therefore, we should be able to simply install the vanilla package via pip. This will also allow us to easily move to Python 3, as Python 3 support was added in version 4.0.0.

Summary: Move teamd functions to a new service script
Motivation: To segregate teamd functions in one common place. fast-reboot script calls teamd functions that should ideally be replaced by a simple call to a service script.
Changes: New teamd service script and path modification from /usr/bin/teamd.sh to /usr/local/bin/teamd.sh
fast-reboot script (in sonic-utilities) modification (to use new teamd.sh to stop teamd) should follow soon after this change.

This change introduces PDDF which is described here: https://github.com/Azure/SONiC/pull/536
Most of the platform bring up effort goes in developing the platform device drivers, SONiC platform APIs and validating them. Typically each platform vendor writes their own drivers and platform APIs which is very tailor made to that platform. This involves writing code, building, installing it on the target platform devices and testing. Many of the details of the platform are hard coded into these drivers, from the HW spec. They go through this cycle repetitively till everything works fine, and is validated before upstreaming the code.
PDDF aims to make this platform driver and platform APIs development process much simpler by providing a data driven development framework. This is enabled by:
JSON descriptor files for platform data
Generic data-driven drivers for various devices
Generic SONiC platform APIs
Vendor specific extensions for customisation and extensibility

FixAzure/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.

As part of the transition from Python 2 to Python 3, we are installing both pip2 and pip3 in the slave and config-engine containers. This PR replaces calls to `pip` in these containers with an explicit call to `pip2` to ensure the proper version of pip is executed, no matter which version of pip is aliased to `pip`, as we no longer rely on that alias.
Also some other pip-related cleanup
To consolidate host services and install via packages instead of file-by-file, also as part of migrating all of SONiC to Python 3, as Python 2 is no longer supported, convert caclmgrd to Python 3 and add to sonic-host-services package
* Initial commit for BGP internal neighbor table support.

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.

The orchagent and syncd need to have the same default synchronous mode configuration. This PR adds a template file to translate the default value in CONFIG_DB (empty field) to an explicit mode so that the orchagent and syncd could have the same default mode.
**- Why I did it**
Install all host services and their data files in package format rather than file-by-file
**- How I did it**
- Create sonic-host-services Python wheel package, currently including procdockerstatsd
- Also add the framework for unit tests by adding one simple procdockerstatsd test case
- Create sonic-host-services-data Debian package which is responsible for installing the related systemd unit files to control the services in the Python wheel. This package will also be responsible for installing any Jinja2 templates and other data files needed by the host services.
**- 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
**- 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:
```

neighbor PEER_V4 allowas-in 1
neighbor PEER_V6 allowas-in 1
```

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.
