**- Why I did it**
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.
**- How I did it**
- Remove Makefiles and patches for building supervisor package from source
- Install Python 3 supervisor package version 4.2.1 in Buster base container
- Also install Python 3 version of supervisord-dependent-startup in Buster base container
- Debian package installed binary in `/usr/bin/`, but pip package installs in `/usr/local/bin/`, so rather than update all absolute paths, I changed all references to simply call `supervisord` and let the system PATH find the executable to prevent future need for changes just in case we ever need to switch back to build a Debian package, then we won't need to modify these again.
- Install Python 2 supervisor package >= 3.4.0 in Stretch and Jessie base containers

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

**- Why I did it**
A memory issue was discovered during system test for scaling. The issue is documented here: https://docs.pyroute2.org/ipdb.html
> One of the major issues with IPDB is its memory footprint. It proved not to be suitable for environments with thousands of routes or neighbours. Being a design issue, it could not be fixed, so a new module was started, NDB, that aims to replace IPDB. IPDB is still more feature rich, but NDB is already more fast and stable.

Recent changes to dependencies caused the 'enum34' package to cease being installed for Python 2 in the PMon container. This broke Arista platforms, where the Arista sonic_platform package imports 'enum'. This is because on Arista devices, the sonic_platform wheel is not installed in the container. Instead, the installation directory is mounted from the host OS. However, this method doesn't ensure all dependencies are installed in the container.
Prevent intermittent build failures when building Sonic for the ARM platform architecture due to version upgrades of the redis-tools and redis-server packages.
Modify select Dockerfile templates to download the redis-tools and redis-server packages from sonicstorage rather than from debian.org.
This PR has been made possible by the inclusion of ARM versions of redis-tools and redis-server into sonicstorage as described in Issue# 5701
* This was a temporary fix for orchagent spamming log messages and causing rate limiting, leading to critical messages being dropped for the syslog. No longer needed since Azure/sonic-sairedis#680 was merged.
On Arista platforms, sonic_platform packages are not installed in the PMon container, but are rather mounted into the container from the host OS. Therefore, pip show sonic_platform will fail in the PMon container. This change will first check if we can import sonic_platform. If this fails, it will then fall back to checking if the package is installed. If both fail, it will attempt to install the package.
Why/How I did:
Make sure first error syslog is triggered based on FAULT TOLERANCE condition.
Added support of repeat clause with alert action. This is used as trigger
for generation of periodic syslog error messages if error is persistent
Updated the monit conf files with repeat every x cycles for the alert action
Increase startretires value from default of 10 to 50 to prevent supervisor from placing thermalctld in FATAL state during regression testing. Also ensures supervisord tries hard to get thermalctld running in production, as thermalctld is critical to prevent device from overheating.
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
Upgrading pip3 after pip2 caused the pip command to be aliased to the pip3 command. However, since we are still transitioning from Python 2 to Python 3, most pip commands in the codebase are expecting pip to alias to pip2. The proper solution here is to explicitly call pip2 and pip3, and no longer call pip, however this will require extensive changes and testing, so to quickly fix this issue, we upgraded pip2 after pip3 to ensure that pip2 is installed after pip3.

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**
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:
```

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

neighbor PEER_V4 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.

We were building our own python-click package because we needed features/bug fixes available as of version 7.0.0, but the most recent version available from Debian was in the 6.x range.
"Click" is needed for building/testing and installing sonic-utilities. Now that we are building sonic-utilities as a wheel, with Click specified as a dependency in the setup.py file, setuptools will install a more recent version of Click in the sonic-slave-buster container when building the package, and pip will install a more recent version of Click in the host OS of SONiC when installing the sonic-utilities package. Also, we don't need to worry about installing the Python 2 or 3 version of the package, as the proper one will be installed as necessary.
**- Why I did it**
FRR introduced [next hop tracking](http://docs.frrouting.org/projects/dev-guide/en/latest/next-hop-tracking.html) functionality.
That functionality requires resolving BGP neighbors before setting BGP connection (or explicit ebgp-multihop command). Sometimes (BGP MONITORS) our neighbors are not directly connected and sessions are IBGP. In this case current configuration prevents FRR to establish BGP connections. Reason would be "waiting for NHT". To fix that we need either add static routes for each not-directly connected ibgp neighbor, or enable command `ip nht resolve-via-default`

We are moving toward building all Python packages for SONiC as wheel packages rather than Debian packages. This will also allow us to more easily transition to Python 3.
Python files are now packaged in "sonic-utilities" Pyhton wheel. Data files are now packaged in "sonic-utilities-data" Debian package.
**- How I did it**
- Build and install sonic-utilities as a Python package
- Remove explicit installation of wheel dependencies, as these will now get installed implicitly by pip when installing sonic-utilities as a wheel
- Build and install new sonic-utilities-data package to install data files required by sonic-utilities applications
- Update all references to sonic-utilities scripts/entrypoints to either reference the new /usr/local/bin/ location or remove absolute path entirely where applicable

This is due to the number of programs in the container managed by supervisor, all generating events at the same time. The default event queue buffer size in supervisor is 10. This patch increases that value in all containers in order to eliminate these errors. As more programs are added to the containers, we may need to further adjust these values. I increased all buffer sizes to 25 except for containers with more programs or templated supervisor.conf files which allow for a variable number of programs. In these cases I increased the buffer size to 50. One final exception is the swss container, where the buffer fills up to ~50, so I increased this buffer to 100.

Root Cause: Waiting on Restore count != 0 can lead to race condition
between orchagent process and swssconfig.sh.
Ideally check of Restore count != 0 is not needed as the State DB
cannot be flushed as if it was flushed then Warm Restart or swss-restart
should not be true also.
Remove radvd Makefile and patch, change docker-router-advertiser Dockerfile template to simply install the vanilla radvd package using apt-get.
- In PR https://github.com/Azure/sonic-buildimage/pull/2795, we started building radvd from source and patching it to prevent it from erroring out when advertising an MTU of 9100 which was greater than the MTU size configured on the bridge interface (1500), which was due to a limitation in the 4.9 Linux kernel.
- Master branch is now using Linux kernel 4.19. As of 4.18, the kernel supports setting a bridge MTU to a value > 1500.
- PR https://github.com/Azure/sonic-swss/pull/1393 modified vlanmgrd to take advantage of this and now configures the MTU of bridge interfaces in SONiC to the proper size of 9100. Therefore, we no longer need to patch radvd. Since we no longer need to patch radvd, we no longer need to build it from source, so we can save build time by going back to simply installing the vanilla radvd Debian package in the router-advertiser container.

The following changes are done.
- Multi asic platform have 2 Loopback interfaces, Loopback0 and Loopback4096. IPinIP decap entries need to be added for both of them. Update the ipinip.json.j2 template to add decap entries for Loopback4096.
- Add corressponding unit test
Add a master switch so that the sync/async mode can be configured.
Example usage of the switch:
1. Configure mode while building an image
`make ENABLE_SYNCHRONOUS_MODE=y <target>`
2. Configure when the device is running
Change CONFIG_DB with `sonic-cfggen -a '{"DEVICE_METADATA":{"localhost": {"synchronous_mode": "enable"}}}' --write-to-db`
Restart swss with `systemctl restart swss`
**- Why I did it**
PR https://github.com/Azure/sonic-buildimage/pull/4599 introduced two bugs in the startup of the router advertiser container:
1. References to the `wait_for_intf.sh` script were changed to `wait_for_link.sh`, but the actual script was not renamed
2. The `ipv6_found` Jinja2 variable added to the supervisor config file goes out of scope before it is read.
**- How I did it**
1. Rename the `wait_for_intf.sh` script to `wait_for_link.sh`
2. Use the Jinja2 "namespace" construct to fix the scope issue
**- How to verify it**
Ensure all processes in the radv container start properly under the correct conditions (i.e., whether or not there is at least one VLAN with an IPv6 address assigned).

Copy proper fancontrol config file to the proper destination. Also some minor refactoring for code reuse to help prevent issues like this in the future.
Fixes a bug introduced by #4599
fixes https://github.com/Azure/sonic-buildimage/issues/5026
Explanation:
In the log from the issue I found:
```
I see following in the log
Jul 22 21:13:06.574831 vlab-01 WARNING bgp#bgpd[49]: [EC 33554499] sendmsg_nexthop: zclient_send_message() failed
```
Analyzing source code I found that the error message could be issues only when `zclient_send_rnh()` return less than 0.
```
ret = zclient_send_rnh(zclient, command, p, exact_match,
bnc->bgp->vrf_id);
/* TBD: handle the failure */
if (ret < 0)
flog_warn(EC_BGP_ZEBRA_SEND,
"sendmsg_nexthop: zclient_send_message() failed");
```
I checked [zclient_send_rnh()](88351c8f6d/lib/zclient.c (L654)) and found that this function will return the exit code which the function gets from [zclient_send_message()](88351c8f6d/lib/zclient.c (L266)) But the latter function could return not 0 in two cases:
1. bgpd didn’t connect to the zclient socket yet [code](88351c8f6d/lib/zclient.c (L269))
2. The socket was closed. But in this case we would receive the error message in the log. (And I can find the message in the log when we reboot sonic) [code](88351c8f6d/lib/zclient.c (L277))
Also I see from the logs that client connection was set later we had the issue in bgpd.
Bgpd.log
```
Jul 22 21:13:06.574831 vlab-01 WARNING bgp#bgpd[49]: [EC 33554499] sendmsg_nexthop: zclient_send_message() failed
```
Vs
Zebra.log
```
Jul 22 21:13:12.713249 vlab-01 NOTICE bgp#zebra[48]: client 25 says hello and bids fair to announce only static routes vrf=0
Jul 22 21:13:12.820352 vlab-01 NOTICE bgp#zebra[48]: client 30 says hello and bids fair to announce only bgp routes vrf=0
Jul 22 21:13:12.820352 vlab-01 NOTICE bgp#zebra[48]: client 33 says hello and bids fair to announce only vnc routes vrf=0
```
So in our case we should start zebra first. Wait until it is started and then start bgpd and other daemons.
**- How I did it**
I changed a graph to start daemons in the following order:
1. First start zebra
2. Then starts staticd and bgpd
3. Then starts vtysh -b and bgpeoi after bgpd is started.
