Why I did it
Support readonly version of the command vtysh
How I did it
Check if the command starting with "show", and verify only contains single command in script.
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.
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.
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.
- 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.

- 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

- 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.

Earlier today we found a bug in the SONiC TSA implementation.
TSC shows incorrect output (see below) in case we have a route-map which contains TSA route-map as a prefix.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Not consistent
```
The reason is that TSC implementation has too loose regexps in TSA utilities, which match wrong route-map entries:
For example, current TSC matches following
```
route-map TO_BGP_PEER_V4 permit 200
route-map TO_BGP_PEER_V6 permit 200
```
But it should match only
```
route-map TO_BGP_PEER_V4 permit 20
route-map TO_BGP_PEER_V4 deny 30
route-map TO_BGP_PEER_V6 permit 20
route-map TO_BGP_PEER_V6 deny 30
```
**- How I did it**
I fixed it by using egrep with `^` and `$` regexp markers which match begin and end of the line.
**- How to verify it**
1. Add follwing entry to FRR config:
```
str-s6100-acs-1#
str-s6100-acs-1# conf t
str-s6100-acs-1(config)# route-map TO_BGP_PEER_V4 permit 200
str-s6100-acs-1(config-route-map)# end
```
2. Use the TSC command and check output. It should show normal.
```
admin@str-s6100-acs-1:~$ TSC
Traffic Shift Check:
System Mode: Normal```

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

1. TSA didn't advertise Loopback ipv6 address

**- 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:
```

**- 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`
**- How I did it**
Put `ip nht resolve-via-default` into the config

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
Submodule updates:
* src/sonic-utilities aa27dd9...2244d7b (5):
> Support building sonic-utilities as a Python wheel package instead of a Debian package (#1122)
> [consutil] Display remote device name in show command (#1120)
> [vrf] fix check state_db error when vrf moving (#1119)
> [consutil] Fix issue where the ConfigDBConnector's reference is missing (#1117)

* src/sonic-ztp dd025bc...911d622 (1):
> Update paths to reflect new sonic-utilities install location, /usr/local/bin/ (#19)
* Add bgpmon under sonic-bgpcfgd to be started as a new daemon under BGP docker
* Added bgpmon to be monitored by Monit so that if it crashed, it gets alerted
* use console_scripts entry point to package bgpmon
When stopping the swss, pmon or bgp containers, log messages like the following can be seen:
```
Aug 23 22:50:43.789760 sonic-dut INFO swss#supervisord 2020-08-23 22:50:10,061 ERRO pool dependent-startup event buffer overflowed, discarding event 34

```
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.

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.

* Loopback IP changes for multi ASIC devices
multi ASIC will have 2 Loopback Interfaces
- Loopback0 has globally unique IP address, which is advertised by the multi ASIC device to its peers.
This way all the external devices will see this device as a single device.
- Loopback4096 is assigned an IP address which has a scope is within the device. Each ASIC has a different ip address for Loopback4096. This ip address will be used as Router-Id by the bgp instance on multi ASIC devices.
This PR implements this change for multi ASIC devices

* Changes to make default route programming
correct in multi-asic platform where frr is not running
in host namespace. Change is to set correct administrative distance.

so that it can be used when needed.
Signed-off-by: Abhishek Dosi <abdosi@microsoft.com>
* Fix review comments
* Review comment to check to add default route
only if default route exist and delete is successful.
**- Why I did it**
Initially, the critical_processes file contains either the name of critical process or the name of group.
For example, the critical_processes file in the dhcp_relay container contains a single group name
`isc-dhcp-relay`. When testing the autorestart feature of each container, we need get all the critical
processes and test whether a container can be restarted correctly if one of its critical processes is
killed. However, it will be difficult to differentiate whether the names in the critical_processes file are
the critical processes or group names. At the same time, changing the syntax in this file will separate the individual process from the groups and also makes it clear to the user.
Right now the critical_processes file contains two different kind of entries. One is "program:xxx" which indicates a critical process. Another is "group:xxx" which indicates a group of critical processes
managed by supervisord using the name "xxx". At the same time, I also updated the logic to
parse the file critical_processes in supervisor-proc-event-listener script.
**- How to verify it**
We can first enable the autorestart feature of a specified container for example `dhcp_relay` by running the comman `sudo config container feature autorestart dhcp_relay enabled` on DUT. Then we can select a critical process from the command `docker top dhcp_relay` and use the command `sudo kill -SIGKILL <pid>` to kill that critical process. Final step is to check whether the container is restarted correctly or not.
* Adding new BGP peer groups PEER_V4_INT and PEER_V6_INT. The internal BGP sessions
will be added to this peer group while the external BGP sessions will be added
to the exising PEER_V4 and PEER_V6 peer group.
* Check for "ASIC" keyword in the hostname to identify the internal neighbors.
- change the references to 'type' field to 'sub_role'
- change the references to 'InternalFrontend' and 'InternalBackend' to 'FrontEnd' and 'BackEnd' respectively
- add a statement to reflect route-reflector for backend asics
- add a change to set "next-hop-self force" configuration for internal BGP session in multi asic platform.

The one big bgp configuration template was splitted into chunks.
Currently we have three types of bgp neighbor peers:
general bgp peers. They are represented by CONFIG_DB::BGP_NEIGHBOR table entries
dynamic bgp peers. They are represented by CONFIG_DB::BGP_PEER_RANGE table entries
monitors bgp peers. They are represented by CONFIG_DB::BGP_MONITORS table entries
This PR introduces three templates for each peer type:
bgp policies: represent policieas that will be applied to the bgp peer-group (ip prefix-lists, route-maps, etc)
bgp peer-group: represent bgp peer group which has common configuration for the bgp peer type and uses bgp routing policy from the previous item
bgp peer-group instance: represent bgp configuration, which will be used to instatiate a bgp peer-group for the bgp peer-type. Usually this one is simple, consist of the referral to the bgp peer-group, bgp peer description and bgp peer ip address.
This PR redefined constant.yml file. Now this file has a setting for to use or don't use bgp_neighbor metadata. This file has more parameters for now, which are not used. They will be used in the next iteration of bgpcfgd.
Currently all tests have been disabled. I'm going to create next PR with the tests right after this PR is merged.
I'm going to introduce better bgpcfgd in a short time. It will include support of dynamic changes for the templates.

- How to verify it
Build an image and run on your DUT
The owner of the generated files (/etc/frr/*.conf) by start.sh is root if it is a new file.
This will cause error when executing "copy running-config startup-config" in vtysh because of privilege issue.

- What I did
Move the interface of bgpcfgd from swsssdk to swsscommon. Because bgpcfgd need to listen more events in the future and we want to maintain one kind of APIs, swsscommon is more suitable than swsssdk.
- How I did it
Refactor the BGPConfigDaemon to two components, Daemon and BGPConfigManager. We can register new managers to the Daemon object if we want to listen more events.
