- Why I did it
Support DSCP remapping in dual ToR topo on T0 switch for SKU Mellanox-SN4600c-C64, Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8.
- How I did it
Regarding buffer settings, originally, there are two lossless PGs and queues 3, 4. In dual ToR scenario, the lossless traffic from the leaf switch to the uplink of the ToR switch can be bounced back.
To avoid PFC deadlock, we need to map the bounce-back lossless traffic to different PGs and queues. Therefore, 2 additional lossless PGs and queues are allocated on uplink ports on ToR switches.
On uplink ports, map DSCP 2/6 to TC 2/6 respectively
On downlink ports, both DSCP 2/6 are still mapped to TC 1
Buffer adjusted according to the ports information:
Mellanox-SN4600c-C64:
56 downlinks 50G + 8 uplinks 100G
Mellanox-SN4600c-D48C40, Mellanox-SN2700, Mellanox-SN2700-D48C8:
24 downlinks 50G + 8 uplinks 100G

Why I did it
The current lazy installer relies on a filename sort for both unpack and configuration steps. When systemd services are configured [started] by multiple packages the order is by filename not by the declared package dependencies. This can cause the start order of services to differ between first-boot and subsequent boots. Declared systemd service dependencies further exacerbate the issue (e.g. blocking the first-boot script).
The current installer leaves packages un-configured if the package dependency order does not match the filename order.
This also fixes a trivial bug in [Build]: Support to use symbol links for lazy installation targets to reduce the image size #10923 where externally downloaded dependencies are duplicated across lazy package device directories.
How I did it
Changed the staging and first-boot scripts to use apt-get:
dpkg -i /host/image-$SONIC_VERSION/platform/$platform/*.deb
becomes
apt-get -y install /host/image-$SONIC_VERSION/platform/$platform/*.deb
when dependencies are detected during image staging.

Why I did it
BGP service has always been starting after interface-config. However, recently we discovered an issue where some BGP sessions are unable to establish due to BGP daemon not able to read the interface IP.
This issue was clearly observed after upgrading to FRR 8.2.2. See more details in #12380.
How I did it
Delaying starting BGP seems to be a workaround for this issue.
However, caution is that this delay might impact warm reboot timing and other timing sequences.
This workaround is reducing the probability of hitting the issue by close to 100X. However, this workaround is not bulletproof as test shows. It is still preferrable to have a proper FRR fix and revert this change in the future.
How to verify it
Continuously issuing config reload and check BGP session status afterwards.

interfaces-config service restarts networking service, during the restart loopback interface address is being removed and reassigned back, leaving loopback without an ipv4 address for a while.

Support mapping DSCP 2/6 to lossless traffic in the QoS template.
Add macros to generate additional lossless PG in the dynamic model
Adjust the order in which the generic/dedicated (with additional lossless queues) macros are checked and called to generate buffer tables in common template buffers_config.j2
Buffer tables are rendered via using macros.
Both generic and dedicated macros are defined on our platform. Currently, the generic one is called as long as it is defined, which causes the generic one always being called on our platform. To avoid it, the dedicated macrio is checked and called first and then the generic ones.
Support MAP_PFC_PRIORITY_TO_PRIORITY_GROUP on ports with additional lossless queues.
On Mellanox-SN4600C-C64, buffer configuration for t1 is calculated as:
40 * 100G downlink ports with 4 lossless PGs/queues, 1 lossy PG, and 3 lossy queues
16 * 100G uplink ports with 2 lossless PGs/queues, 1 lossy PG, and 5 lossy queues

It's because for some HWSKU, such as BackEndToRRouter and BackEndLeafRouter, there is no DSCP_TO_TC_MAP defined.
Hence, if the PORT_QOS_MAP|global entry is generated, OA will report some error because the DSCP_TO_TC_MAP map AZURE can not be found.

DSCP_TO_TC_MAP
Before After Why do this change
"2" : "1" "2" : "2" Only change for leaf router to map DSCP 2 to TC 2 as TC 2 will be used for lossless TC
"6" : "1" "6" : "6" Only change for leaf router to map DSCP 6 to TC 6 as TC 6 will be used for lossless TC
TC_TO_PRIORITY_GROUP_MAP
Before After Why do this change
"2" : "0" "2" : "2" Only change for leaf router to map TC 2 to PG 2 as PG 2 will be used for lossless PG
"6" : "0" "6" : "6" Only change for leaf router to map TC 6 to PG 6 as PG 6 will be used for lossless PG
So, we have two new lossy PGs (2 and 6) for the T2 facing ports on T1, and two new lossless PGs (2 and 6) for the T0 facing port on T1.
However, there is no lossy PG profile for the T2 facing ports on T1. The lossless PGs for ports between T1 and T0 have been handled by buffermgrd .Therefore, We need to add lossy PG profiles for T2 facing ports on T1.
We don't have this issue on T0 because PG 2 and PG 6 are lossless PGs, and there is no lossy traffic mapped to PG 2 and PG 6
Map port level TC7 to PG0
Before the PCBB change, DSCP48 -> TC 6 -> PG 0.
After the PCBB change, DSCP48 -> TC 7 -> PG 7
Actually, we can map TC7 to PG0 to save a lossy PG.

Support to use symbol links in platform folder to reduce the image size.
The current solution is to copy each lazy installation targets (xxx.deb files) to each of the folders in the platform folder. The size will keep growing when more and more packages added in the platform folder. For cisco-8000 as an example, the size will be up to 2G, while most of them are duplicate packages in the platform folder.
How I did it
Create a new folder in platform/common, all the deb packages are copied to the folder, any other folders where use the packages are the symbol links to the common folder.
Why platform.tar?
We have implemented a patch for it, see #10775, but the problem is the the onie use really old unzip version, cannot support the symbol links.
The current solution is similar to the PR 10775, but make the platform folder into a tar package, which can be supported by onie. During the installation, the package.tar will be extracted to the original folder and removed.

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
At present, there is no mechanism in an event driven model to know that the system is up with all the essential sonic services and also, all the docker apps are ready along with port ready status to start the network traffic. With the asynchronous architecture of SONiC, we will not be able to verify if the config has been applied all the way down to the HW. But we can get the closest up status of each app and arrive at the system readiness.
How I did it
A new python based system monitor tool is introduced under system-health framework to monitor all the essential system host services including docker wrapper services on an event based model and declare the system is ready. This framework gives provision for docker apps to notify its closest up status. CLIs are provided to fetch the current system status and also service running status and its app ready status along with failure reason if any.
How to verify it
"show system-health sysready-status" click CLI
Syslogs for system ready
Why I did it
The image size is too large, when there are multiple lazy packages and multiple platforms. It is not necessary to keep the lazy installation packages in multiple copies.
For cisco image, the image size will reduce from 3.5G to 1.7G.
How I did it
Use symbol links to only keep one package for each of the lazy package.
Make a new folder fsroot/platform/common
Copy the lazy packages into the folder.
When using a package in each of the platform, such as x86_64-grub, x86_64-8800_rp-r0, x86_64-8201_on-r0, etc, only make a symbol link to the package in the common folder.
