- Why I did it
To give SONiC Application Extension developers an environment to run and develop their apps.
- How I did it
Created sonic-sdk and sonic-sdk-buildenv dockers and their dbg versions.
- How to verify it
Build:
$ make -f slave target/sonic-sdk.gz target/sonic-sdk-buildenv.gz
#### Why I did it
To avoid the following logs
```
Mar 15 15:52:04.599302 igk-dut-04 INFO database#/supervisord: flushdb /bin/bash: /usr/local/bin/flush_unused_database: /usr/bin/python: bad interpreter: No such file or directory

```
#### How I did it
Fix shebang
#### How to verify it
Check the logs
fuser support is required since new cisco hardware watchdog plugin uses them to check anyone else use's /dev/watchdogX resource. The actual validation happens in the platform code, but the package is required for pmon container. Currently the /dev/watchdogX is being used by cisco platform-monitor service. Cisco chassis level watchdog plugin uses "fuser" to claim the watchdog release from platform-monitor service.
#### Why I did it
MSN4700 A1/A0 used different sensor chip but keep the existing platform name *x86_64-mlnx_msn4700-r0*, this is a workaround to replace the sensor conf on MSN4700 A1/A0
#### How I did it
Use a shell script to get the sensor conf path and copy that files to /etc/sensors.d/sensors.conf
Why I did it
ndppd by default reads /proc/net/ipv6_route ever 30 seconds. Since T1s advertise so many routes to ToRs, this file is extremely large, and reading it causes ndppd's CPU usage to spike every 30 seconds
How I did it
Increase the delay for reading this file to the maximum possible value (max integer value), which will result in CPU spikes every ~24 days instead of every 30 seconds
How to verify it
Start ndppd with the new config file, confirm that no CPU spikes are seen except at startup

For the split mode, the config files, like bgpd.conf, zebra.conf and so on, were provided by outside. But the docker_init.sh will overwrite the outside config files if restart bgp service.
How I did it
Add a split mode checking in docker_init.sh, if docker_routing_config_mode is split, don't overwrite the existing routing config files.
How to verify it
Set split mode in config db
{
"DEVICE_METADATA": {
"localhost": {
"hwsku": "Force10-S6000",
"platform": "x86_64-kvm_x86_64-r0",
"docker_routing_config_mode": "split"
...
}
}
}
Replace your bgpd.conf to /etc/sonic/frr/bgpd.conf
Restart bgp service by sudo service bgp restart
The /etc/sonic/frr/bgpd.conf your provided shouldn't be overwritten

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.

With the latest 201911 image, the following error was seen on staging devices with TSB command ( for both single asic, multi asic ). Though this err message doesn't affect the TSB functionality, it is good to fix.
admin@STG01-0101-0102-01T1:~$ TSB
BGP0 : % Could not find route-map entry TO_TIER0_V4 20
line 1: Failure to communicate[13] to zebra, line: no route-map TO_TIER0_V4 permit 20
% Could not find route-map entry TO_TIER0_V4 30
line 2: Failure to communicate[13] to zebra, line: no route-map TO_TIER0_V4 deny 30
In addition, in this PR I am fixing the message displayed to user when there are no BGP neighbors configured on that BGP instance. In multi-asic device there could be case where there are no BGP neighbors configured on a particular ASIC.
Avoid the following error messages while dynamic buffer calculation is enabled
```
ERR monit[491]: 'swss|buffermgrd' status failed (1) -- '/usr/bin/buffermgrd -l' is not running in host
```
Change /usr/bin/buffermgrd -l to /usr/bin/buffermgrd. The buffermgrd is started by -l for traditional model or -a for dynamic model. So we need to use the common section of both.

The default bgp connect retry timer is 120 seconds. A reconnection will happen 120 seconds if the initial connection fails. This PR aims to allow a more frequent retry.
Why I did it
It was observed that on a multi-asic DUT bootup, the BGP internal sessions between ASIC's was taking more time to get ESTABLISHED than external BGP sessions. The internal sessions was coming up almost exactly 120 secs later.
In multi-asic platform the bgp dockers ( which is per ASIC ) on switch start are bring brought up around the same time and they try to make the bgp sessions with neighbors (in peer ASIC's) which may be not be completely up. This results in BGP connect fail and the retry happens after 120sec which is the default Connect Retry Timer
How I did it
Add the command to set the bgp neighboring session retry timer to 10sec for internal bgp neighbors.
#### Why I did it
It is possible to have DHCP relay configuration with no servers/
helpers which result in DHCP container to crash. This PR fixes this
issue by not starting DHCP relay for vlans with no DHCP helpers.
resolves: #6931closes: #6931
#### How I did it
Do not add program group for dhcp relay with not dhcp helpers
#### How to verify it
Unit test
1. Made the command next-hop-self force only applicable on back-end asic bgp. This is done so that BGPL iBGP session running on backend can send e-BGP learn nexthop. Back end asic FRR is able to recursively resolve the eBGP nexthop in its routing table since it knows about all the connected routes advertise from front end asic.
2. Made all front-end asic bgp use global loopback ip (Loopback0) as router id and back end asic bgp use Loopbacl4096 as ruter-id and originator id for Route-Reflector. This is done so that routes learnt by external peer do not see Loopback4096 as router id in show ip bgp <route-prerfix> output.
3. To handle above change need to pass Loopback4096 from BGP manager for jinja2 template generation. This was missing and this change/fix is needed for this also https://github.com/Azure/sonic-buildimage/blob/master/dockers/docker-fpm-frr/frr/bgpd/templates/dynamic/instance.conf.j2#L27
4. Enhancement to add mult_asic specific bgpd template generation unit test cases.
Enable BBR config allowas-in 1 for internal peers
Why I did:
To advertise BBR routes learnt via e-BGP peer in one asic/namespace to another iBGP asic/namespace via Route Reflector.
adding noTLS mode for debugging purpose
Removing config-set for port 8080. It fails to start telemetry if docker restarts in case on noTLS mode because it expects log_level config to be present as well.
- Introduced TS common file in docker as well and moved common functions.
- TSA/B/C scripts run only in BGP instances for front end ASICs.
In addition skip enforcing it on route maps used between internal BGP sessions.

The requirement for zebra to be ready to accept connections is a generic problem that is not

Recent changes brought l2 vlan concept which do not have DHCP
clients behind them and so DHCP relay is not required. Also,
dhcpmon fails to launch on those vlans as their interfaces
lack IP addresses. This PR limit launch of both DHCP relay
and dhcpmon to L3 vlans only.

- Support for non-template based FRR configurations (BGP, route-map, OSPF, static route..etc) using config DB schema.
- Support for save & restore - Jinja template based config-DB data read and apply to FRR during startup
**- How I did it**
- add frrcfgd service
- when frr_mgmg_framework_config is set, frrcfgd starts in bgp container
- when user changed the BGP or other related table entries in config DB, frrcfgd will run corresponding VTYSH commands to program on FRR.
- add jinja template to generate FRR config file to be used by FRR daemons while bgp container restarted
**- How to verify it**
1. Add/delete data on config DB and then run VTYSH "show running-config" command to check if FRR configuration changed.
1. Restart bgp container and check if generated FRR config file is correct and run VTYSH "show running-config" command to check if FRR configuration is consistent with attributes in config DB

Ledd is the last daemon that is not enabled to run in python3.
Even though there is a plan to deprecate this daemon and to replace it by something else it's one simple step toward python2 deprecation.
**- How I did it**
Changed the `command=` line for `ledd` in the `supervisord` configuration of `pmon`.
Copied what was done for other daemons.
**- How to verify it**
Booting a product that has a `led_control.py` should now show the ledd running in python3.
I ran `python3 -m pylint` on all `led_control.py` plugin which means that most of them should be python3 compliant.
There is however still a risk that some might not work.
- Why I did it
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.

Fix#5026
There is a race condition between zebra server accepts connections and bgpd tries to connect. Bgpd has a chance to try to connect before zebra is ready. In this scenario, bgpd will try again after 10 seconds and operate as normal within these 10 seconds. As a consequence, whatever bgpd tries to sent to zebra will be missing in the 10 seconds. To avoid such a scenario, bgpd should start after zebra is ready to accept connections.
