- Why I did it
New security feature for enforcing strong passwords when login or changing passwords of existing users into the switch.
- How I did it
By using mainly Linux package named pam-cracklib that support the enforcement of user passwords, the daemon named hostcfgd, will support add/modify password policies that enforce and strengthen the user passwords.
- How to verify it
Manually Verification-
1. Enable the feature, using the new sonic-cli command passw-hardening or manually add the password hardening table like shown in HLD by using redis-cli command
2. Change password policies manually like in step 1.
Notes:
password hardening CLI can be found in sonic-utilities repo-
P.R: Add support for Password Hardening sonic-utilities#2121
code config path: config/plugins/sonic-passwh_yang.py
code show path: show/plugins/sonic-passwh_yang.py
3. Create a new user (using adduser command) or modify an existing password by using passwd command in the terminal. And it will now request a strong password instead of default linux policies.
Automatic Verification - Unitest:
This PR contained unitest that cover:
1. test default init values of the feature in PAM files
2. test all the types of classes policies supported by the feature in PAM files
3. test aging policy configuration in PAM files

This PR brings two changes
Add lossy PG profile for PG2 and PG6 on T1 for ports between T1 and T2.
After PR Update qos config to clear queues for bounced back traffic #10176 , the DSCP_TO_TC_MAP and TC_TO_PG_MAP is updated when remapping is enable
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.
How I did it
Update the qos and buffer template.
How to verify it

Why I did it
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.

Revert the PR #10775, for it has impact on onie installation.
It is caused by the symbol links not supported in some of the onie unzip.
We will enable after fixing the issue, see #10914
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.

Profiling the system state on init after fast-reboot during create_switch function execution, it is possible to see few python scripts running at the same time.
This parallel execution consume CPU time and the duration of create_switch is longer than it should be.
Following this finding, and the motivation to ensure these services will not interfere in the future, PMON is delayed in 90 seconds until the system finish the init flow after fastboot.
- How I did it
Add a timer for PMON service.
Exclude for MLNX platform the start trigger of PMON when SYNCD starts in case of fastboot.
Copy the timer file to the host bin image.
- How to verify it
Run fast-reboot on MLNX platform and observe faster create_switch execution time.

container stop() has a timeout (60s) for syncd (the same as for swss)
This is so libasan has enough time to generate a report.

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.

The reason for the failure is due to the fact that there is a new line generated at the top of the file in buffer config test cases while building for broadcom based platform and this issue is not seen in Marvell based platforms.
How I did it
Removed the new line for all the buffer test cases as there is no need to add it and accordingly changed the buffer_config.j2 where the new line is generated.
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.
