When using trap on SIGTERM the script will not react to the SIGTERM signal sent while a child is executing.
I.e, the following script does not react on SIGTERM sent to it if it is
waiting for sleep to finish:
```
trap "echo Handled SIGTERM" 0 2 3 15
echo "Before sleep"
sleep inf
echo "After sleep"
```
Instead, trap only on EXIT which covers also a scenario with exit on
SIGINT, SIGTERM.

In arp_update, check for FAILED or INCOMPLETE kernel neighbor entries and manually ping them to try and resolve the neighbor
Signed-off-by: Lawrence Lee <lawlee@microsoft.com>
Why I did it
The initial value has to be present for the state machines to work. In active-standby dual-tor scenario, or any hardware mux scenario, the value will be updtaed eventually with a delay.
However, in active-active dual-tor scenario, there is no other mechanism to initialize the value and get state machines started.
So this script will have to write something at start up time.
For active-active dualtor, 'active' is a more preferred initial value, the state machine will switch the state to standby soon if
link prober found link not in good state.
How I did it
Update the script to always provide initial values.
How to verify it
Tested on active-active dual-tor testbed.

*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 I did:
Added bgp as a dependent of swss
Why I did it:
bgp container was not restarting on swss crash. When swss crashes, linkmgrd
doesn't initate a switchover because it cannot access the default route from
orchagent. Bringing down bgp with swss will isolate the ToR, causing linkmgrd
to initiate a switchover to the peer ToR avoiding significant packet loss.
How I did it:
Added bgp to DEPENDENT

* Ported Marvell armhf build on x86 for debian buster to use cross-compilation instead of qemu emulation
Current armhf Sonic build on amd64 host uses qemu emulation. Due to the
nature of the emulation it takes a very long time, about 22-24 hours to
complete the build. The change I did to reduce the building time by
porting Sonic armhf build on amd64 host for Marvell platform for debian
buster to use cross-compilation on arm64 host for armhf target. The
overall Sonic armhf building time using cross-compilation reduced to
about 6 hours.

How I did it
Add a flag require_global_dscp_to_tc_map to control whether to generate the PORT_QOS_MAP|global entry. The default value for require_global_dscp_to_tc_map is true. If the device type is storage backend, the value is changed to false. Then the PORT_QOS_MAP|global entry is not generated.
How to verify it
Update the current test_qos_dscp_remapping_render_template to cover storage backend.
Refactors the SONiC Installer to support greater flexibility in building for a given architecture and bootloader.
#### Why I did it
Currently the SONiC installer assumes that if a platform is ARM based that it uses the `uboot` bootloader and uses the `grub` bootloader otherwise. This is not a correct assumption to make as ARM is not strictly tied to uboot and x86 is not strictly tied to grub.
#### How I did it
To implement this I introduce the following changes:
* Remove the different arch folders from the `installer/` directory
* Merge the generic components of the ARM and x86 installer into `installer/installer.sh`
* Refactor x86 + grub specific functions into `installer/default_platform.conf`
* Modify installer to call `default_platform.conf` file and also call `platform/[platform]/patform.conf` file as well to override as needed
* Update references to the installer in the `build_image.sh` script
* Add `TARGET_BOOTLOADER` variable that is by default `uboot` for ARM devices and `grub` for x86 unless overridden in `platform/[platform]/rules.mk`
* Update bootloader logic in `build_debian.sh` to be based on `TARGET_BOOTLOADER` instead of `TARGET_ARCH` and to reference the grub package in a generic manner
#### How to verify it
This has been tested on a ARM test platform as well as on Mellanox amd64 switches as well to ensure there was no impact.

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.

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.

- Why I did it
Recent change to delay PMON service in case of fast/warm reboot introduce an issue when restarting only SWSS service after fast/warm reboot for Nvidia platform.
Since the timer is triggered only when the system boot, in a scenario when the system is after a fast/warm reboot and the user restart SWSS service, as part of syncd.sh script, PMON service will stop but the timer will not start again.
- How I did it
On syncd.sh script, in case of fast/warm indication, check if pmon.timer is running.
If it is running it means we are at the first boot and continue normally.
If it is not running, meaning the service was restarted, start the timer to keep the system behavior consistent.

This reverts commit 15cf9b0d70.
Why I did it
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.

New option 'ssd-upgrader-part’ is introduced in grub command line, to indicate the partition and its filesystem type in which the SSD firmware updater is present. ‘ssd-upgrader-part’ syntax is ssd-upgrader-part=<partition>,<filesystem type>. Example: ssd-upgrader-part=/dev/sda8,ext4
A new initramfs script ‘ssd-upgrade’ is included in init-premount and it invokes the SSD firmware updater (ssd-fw-upgrade) present in the partition indicated by the boot option 'ssd-upgrader-part'
How to verify it
In SONiC, the SSD firmware updater is copied to “/host/” directory.
Fast-reboot is to be initiated with the ‘-u’ option ([scripts/fast-reboot] Add option to include ssd-upgrader-part boot option with SONiC partition sonic-utilities#2150)
After reboot, while booting into SONiC the SSD firmware updater will be executed in initramfs.
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.
Why I did it
The PR is aimed to fix a bug that mgmt port eth0 may loss IP even if user configured static IP of eth0. This is not a always reproduceable issue, the reproducing flow is like:
Systemd starts networking service, which runs a dhcp based configuration and assigned an ip from dhcp.
Systemd starts interface-config service who depends on networking service
Interface-config service runs command “ifdown –force eth0”, check line. but networking service is still running so that this line failed with error: “error: Another instance of this program is already running.”. This error is printed by ifupdown2 lib who is the main process of networking service. So, ifdown actually does not work here, the ip of eth0 is not down.
Interface-config service updates /etc/networking/interface to static configuration.
Interface-config service runs command “systemctl restart networking”. This command kills the previous networking related processes (log: networking.service: Main process exited, code=killed, status=15/TERM), and try to reconfigure the ip address with static configuration. But it detects that the configured IP and the existing IP are the same, and it does not really configure the ip to kernel. Hence, the ip is still getting from dhcp. (this could be a bug of ifupdown2: previous ip is from dhcp, new ip is a static ip, it treats them as same instead of re-configuring the IP)
When the lease of the ip expires, the ip of eth0 is removed by kernel and the issue reproduces.
The issue is not always reproduceable because networking service usually runs fast so that it won't hit step#3.
How I did it
Check networking service state before running "ifdown –force eth0", wait for it done if it is activating.
How to verify it
Manual test.
- Why I did it
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.

Why I did it
This PR aims to fix the Monit issue which shows Monit can't reset its counter when monitoring memory usage of telemetry container.
Specifically the Monit configuration file related to monitoring memory usage of telemetry container is as following:
check program container_memory_telemetry with path "/usr/bin/memory_checker telemetry 419430400"
if status == 3 for 10 times within 20 cycles then exec "/usr/bin/restart_service telemetry"
If memory usage of telemetry container is larger than 400MB for 10 times within 20 cycles (minutes), then it will be restarted.
Recently we observed, after telemetry container was restarted, its memory usage continuously increased from 400MB to 11GB within 1 hour, but it was not restarted anymore during this 1 hour sliding window.
The reason is Monit can't reset its counter to count again and Monit can reset its counter if and only if the status of monitored service was changed from Status failed to Status ok. However, during this 1 hour sliding window, the status of monitored service was not changed from Status failed to Status ok.
Currently for each service monitored by Monit, there will be an entry showing the monitoring status, monitoring mode etc. For example, the following output from command sudo monit status shows the status of monitored service to monitor memory usage of telemetry:
Program 'container_memory_telemetry'
status Status ok
monitoring status Monitored
monitoring mode active
on reboot start
last exit value 0
last output -
data collected Sat, 19 Mar 2022 19:56:26
Every 1 minute, Monit will run the script to check the memory usage of telemetry and update the counter if memory usage is larger than 400MB. If Monit checked the counter and found memory usage of telemetry is larger than 400MB for 10 times
within 20 minutes, then telemetry container was restarted. Following is an example status of monitored service:
Program 'container_memory_telemetry'
status Status failed
monitoring status Monitored
monitoring mode active
on reboot start
last exit value 0
last output -
data collected Tue, 01 Feb 2022 22:52:55
After telemetry container was restarted. we found memory usage of telemetry increased rapidly from around 100MB to more than 400MB during 1 minute and status of monitored service did not have a chance to be changed from Status failed to Status ok.
How I did it
In order to provide a workaround for this issue, Monit recently introduced another syntax format repeat every <n> cycles related to exec. This new syntax format will enable Monit repeat executing the background script if the error persists for a given number of cycles.
How to verify it
I verified this change on lab device str-s6000-acs-12. Another pytest PR (Azure/sonic-mgmt#5492) is submitted in sonic-mgmt repo for review.
The interface renaming logic fails if one interface is missing.
Because of the `set -e` the whole initramfs hook would abort early on
error.
This change fixes the current behavior to make sure missing interfaces
are properly skipped and ensure existing interface are renamed.

If having gearbox, we need:
* add gbsyncd as a peer since swss also has dependency on gbsyncd

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.

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.

On some products the pci enumeration adds randomness into which nic gets

Because SONiC doesn't use deterministic interface naming but instead old

# Why I did it
Reduce the disk space taken up during bootup and runtime.
# How I did it
1. Remove python package cache from the base image and from the containers.
2. During bootup, if logs are to be stored in memory, then don't create the `var-log.ext4` file just to delete it later during bootup.
3. For the partition containing `/host`, don't reserve any blocks for just the root user. This just makes sure all disk space is available for all users, if needed during upgrades (for example).
* Remove pip2 and pip3 caches from some containers
Only containers which appeared to have a significant pip cache size are
included here.

Why I did it
The marvel-armhf build is hung, it does not exit after waiting for a long time.
It is caused by the process /etc/entropy.py which is started by the postinst script in target/debs/buster/sonic-platform-nokia-7215_1.0_armhf.deb
When mounting the partition that contains `/host` during initramfs, the
mount binary available there (coming from busybox) tries each filesystem
in `/proc/filesystems` and sees which one succeeds. During this time,
there may be some error messages logged into dmesg because some of the
incorrect filesystems failed to mount the partition.
Specify the filesystem type explicitly so that initramfs knows it's that
type, and we know what filesystem will always get used there.

Implement infrastructure that allows enabling address sanitizer

- 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.
