Multi-asic Docker instances are created behind Docker's default bridge
which doesn't allow talking to other Docker instances that are in the
host network (like database-chassis).
On linecards, we configure midplane interfaces to let per-asic docker
containers talk to CHASSIS_DB on the supervisor through internal chassis
network.
On the supervisor we don't need to use chassis internal network, but we
still need a similar setup in order to allow fabric containers to talk
to database-chassis
*Preventing ebtables rules to be applied on KVM image. The ebtables rules in SONiC are added to prevent ARP as well as L2 forwarding to be blocked in linux kernel since the hardware will take care of the actual L2 forward. However this is not the case with KVM where linux needs to forward even L2 packets
What/Why I did:
Issue1: By setting up of ipvlan interface in interface-config.sh we are not tolerant to failures. Reason being interface-config.service is one-shot and do not have restart capability.
Scenario: For example if let's say database service goes in fail state then interface-services also gets failed because of dependency check but later database service gets restart but interface service will remain in stuck state and the ipvlan interface nevers get created.
Solution: Moved all the logic in database service from interface-config service which looks more align logically also since the namespace is created here and all the network setting (sysctl) are happening here.With this if database starts we recreate the interface.
Issue 2: Use of IPVLAN vs MACVLAN
Currently we are using ipvlan mode. However above failure scenario is not handle correctly by ipvlan mode. Once the ipvlan interface is created and ip address assign to it and if we restart interface-config or database (new PR) service Linux Kernel gives error "Error: Address already assigned to an ipvlan device." based on this:https://github.com/torvalds/linux/blob/master/drivers/net/ipvlan/ipvlan_main.c#L978Reason being if we do not do cleanup of ip address assignment (need to be unique for IPVLAN) it remains in Kernel Database and never goes to free pool even though namespace is deleted.
Solution: Considering this hard dependency of unique ip macvlan mode is better for us and since everything is managed by Linux Kernel and no dependency for on user configured IP address.
Issue3: Namespace database Service do not check reachability to Supervisor Redis Chassis Server.
Currently there is no explicit check as we never do Redis PING from namespace to Supervisor Redis Chassis Server. With this check it's possible we will start database and all other docker even though there is no connectivity and will hit the error/failure late in cycle
Solution: Added explicit PING from namespace that will check this reachability.
Issue 4:flushdb give exception when trying to accces Chassis Server DB over Unix Sokcet.
Solution: Handle gracefully via try..except and log the message.
Why I did it
To support address sanitizer for Mellanox syncd
How I did it
/var/log/asan is mapped for syncd container (the same as for swss)
container stop() has a timeout (60s) for syncd (the same as for swss)
This is so libasan has enough time to generate a report.
added ASAN's log path to Mellanox syncd supervisord.conf
added "asan: yes" to sonic_version.yml
How to verify it
Added artificial memory leaks
Compiled with ENABLE_ASAN=y
Installed the image on DUT
Rebooted the DUT
Verified that /var/log/asan/syncd-asan.log contains the leaks
Signed-off-by: Yakiv Huryk <yhuryk@nvidia.com>
Why I did it
In the bringup of tomahawk4/trident4, we realized that such chips need a larger size of /dev/shm in syncd container, so we added the option --shm-size to the docker create for syncd. The default value for shm-size is 64m; after this change, people can add SYNCD_SHM_SIZE=128m to platform_env.conf to change it to 128m.
How to verify it
We verified that after this change, 1) on existing platforms without platform_env.conf, the size of /dev/shm in syncd container (df -h | grep shm) is still the default 64M; 2) after we add SYNCD_SHM_SIZE=128m to platform_env.conf, /dev/shm in syncd becomes 128M.
Implement infrastructure that allows enabling address sanitizer
for docker containers. Enable address sanitizer for SWSS container.
- Why I did it
To add a possibility to compile SONiC applications with address sanitizer (ASAN).
ASAN is a memory error detector for C/C++. It finds:
1. Use after free (dangling pointer dereference)
2. Heap buffer overflow
3. Stack buffer overflow
4. Global buffer overflow
5. Use after return
6. Use after the scope
7. Initialization order bugs
8. Memory leaks
- How I did it
By adding new ENABLE_ASAN configuration option.
- How to verify it
By default ASAN is disabled and the SONiC image is not affected.
When ASAN is enabled it inspects all allocation, deallocation, and memory usage that the application does in run time. To verify whether the application has memory errors tests that trigger memory usage of the application should be run. Ideally, the whole regression tests should be run. Memory leaks reports will be placed in /var/log/asan/ directory of SONiC host OS.

As a part of warmboot, redis database is dumped:

However, this dump file is deleted, after it is loaded back into db post reboot.
The DB dump can be useful for debugging purpose, hence taking a backup of it can be useful.
Instead of deleting the dump, rename and keep the dump.
#### Why I did it
Use a predefined variable to get vendor information when the swss docker container is created
#### How I did it
Use `{{ sonic_asic_platform }}` instead of `$SONIC_CFGGEN -y /etc/sonic/sonic_version.yml -v asic_type`
#### How to verify it
Manually test.

The voq system lag id boundary is set in redis-chassis. Changes include
setting this from database-chassis container. This fixes a timing issue
in finding datbase_config.json file from redis directory which is
created from database container. Since database container usually
starts after database-chassis container the existence of this file is
unreliable while running the command. Running the command under
database-chassis container makes sure that the database_config.json form
redis-chassis directory is guaranteed to be available and hence fixes the

I made the docker_img_ctl.j2 applicable for more dockers (including application extensions dockers) by adding an option not to mount tmpfs on /tmp/ and /var/tmp/. In some applications /tmp/ is a different docker volume which can't be tmpfs.
Also, I added and ability to pass REPO[:TAG]|[@digest]/IMAGE_ID instead of just REPO name.
- How I did it
Modified docker_img_ctl.j2 and docker makefiles.
- How to verify it

- For Multi-asic platforms we don't want to install on host otherwise Namespace-to-Namespace communication does not happens since ARP Request are not forwarded.
- Updated to use text file to restore ebtables rules then the binary format. Rules are restore as part of Database docker init instead of rc.local
- Removed the ebtable service files for buster as not needed as filters are restored/installed as part of database docker init.

* 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.
**- Why I did it**
To support dynamic buffer calculation.
This PR also depends on the following PRs for sub modules
- [sonic-swss: [buffermgr/bufferorch] Support dynamic buffer calculation #1338](https://github.com/Azure/sonic-swss/pull/1338)
- [sonic-swss-common: Dynamic buffer calculation #361](https://github.com/Azure/sonic-swss-common/pull/361)
- [sonic-utilities: Support dynamic buffer calculation #973](https://github.com/Azure/sonic-utilities/pull/973)
**- 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
8. Remove buffer pool sizes for ingress pools and egress_lossy_pool
Update the buffer settings for dynamic buffer calculation

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.

- 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

Take advantage of an SDK environment variable to customize the location where sdk_socket exists.
In the latest SDK sdk_socket has been moved from /tmp to /var/run which is a better place to contain this kind of file.
However, this prevents the subdirs under /var/run from being mapped to different volumes. To resolve this, we take advantage of an SDK variable to designate the location of sdk_socket.
This requires every process that requires to access sdk_socket have this environment variable defined. However, to define environment variable for each process is less scalable. We take advantage of the docker scope environment variable to avoid that.
It depends on PR 4227
