System Ready (#10479)
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

Reduce image size for lazy installation packages (#10775)
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.

[Fastboot] Delay PMON service for better fastboot performance (#10567)
- 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.

[Mellanox] Modified Platform API to support all firmware updates in single boot (#9608)
Why I did it
Requirements from Microsoft for fwutil update all state that all firmwares which support this upgrade flow must support upgrade within a single boot cycle. This conflicted with a number of Mellanox upgrade flows which have been revised to safely meet this requirement.

How I did it
Added --no-power-cycle flags to SSD and ONIE firmware scripts
Modified Platform API to call firmware upgrade flows with this new flag during fwutil update all
Added a script to our reboot plugin to handle installing firmwares in the correct order with prior to reboot
How to verify it
Populate platform_components.json with firmware for CPLD / BIOS / ONIE / SSD
Execute fwutil update all fw --boot cold
CPLD will burn / ONIE and BIOS images will stage / SSD will schedule for reboot
Reboot the switch
SSD will install / CPLD will refresh / switch will power cycle into ONIE
ONIE installer will upgrade ONIE and BIOS / switch will reboot back into SONiC
In SONiC run fwutil show status to check that all firmware upgrades were successful

[rsyslog]Setting log file size to 16Mb (#9504)
Why I did it
The existing log file size in sonic is 1 Mb. Over a period of time this leads to huge number of log files which becomes difficult for monitoring applications to handle.
Instead of large number of small files, the size of the log file is not set to 16 Mb which reduces the number of files over a period of time.

How I did it
Changed the size parameter and related macros in logrotate config for rsyslog

How to verify it
Execute logrotate manually and verify the limit when the file gets rotated.

c8b5daed27 Upgrade to ifupdown2 3.0.0 with a patch to fix using broadcast addresses
In version 3.0.0, If a broadcast address is specified in
/etc/network/interfaces, then when ifup is run, it will fail with an
error saying `'str' object has no attribute 'packed'`. This appears to
be because it expects all attributes for an interface to be "packable"
into a compact binary representation. However, it doesn't actually
convert the broadcast address into an IPNetwork object (other addresses
are handled).

Therefore, convert the broadcast address it reads in from a str to an
IPNetwork object.

Also explicitly specify the scope of the loopback address in
/etc/network/interfaces as host scope. Otherwise, it will get added as
global scope by default. As part of this, use JSON to parse ip's output
instead of text, for robustness.

[gearbox] Add gbsyncd container for Credo gearbox chips (#8144)
This change is to add a gbsyncd container to accommodate the syncd process and the SAI libraries for the Credo gearbox chips.

How I did it
This container works similar to the existing Broadcom syncd container. Its main difference is that the SAI-related dynamic libraries are replaced by the ones for Credo gearbox chips, and the container only reacts to SAI events for the gearbox chips. The SAI libraries will be provided by the package libsai-credo_1.0_amd64.deb.

For the image build, the added container will be built and included in the Broadcom platform image, after $(LIBSAI_CREDO)_URL = is replaced to the correct value. For now, as $(LIBSAI_CREDO)_URL is empty, the container build is skipped in the image build.

After the container is included in the image, in the runtime, the container will begin with checking the existence of /usr/share/sonic/hwsku/gearbox_config.json; if that file is not provided, the container will exit by itself. Therefore, for platforms unrelated to the Credo chips, as long as they are not providing the file, they will not be affected by this change.

[systemd] ASIC status based service bringup on VOQ chassis (#7477)
Changes to allow starting per asic services like swss and syncd only if the platform vendor codedetects the asic is detected and notified. The systemd services ordering we want is database->database@->pmon->swss@->syncd@->teamd@->lldp@
There is also a requirement that management, telemetry, snmp dockers can start even if all asic services are not up.

Why I did it
For VOQ chassis, the fabric cards will have 1-N asics. Also, there could be multiple removable fabric cards. On the supervisor, swss and syncd containers need to be started only if the fabric-card is in Online state and respective asics are detected by the kernel. Using systemd, the dependent services can be in inactive state.

How I did it
Introduce a mechanism where all ASIC dependent service wait on its state to be published via PMON to REDIS. Once the subscription is received, the service proceeds to create respective dockers.
For fixed platforms, systemd is unchanged i.e. the service bring up and docker creation happens in the start()/ExecStartPre routine of the .sh scripts.
For VOQ chassis platform on supervisor, the service bringup skips docker creation in the start() routine, but does it in the wait()/ExecStart routine of the .sh scrips.
Management dockers are decoupled from ASIC docker creation.

sonic-broadcom.bin, sonic-broadcom-dnx.bin
sonic-aboot-broadcom.swi, sonic-aboot-broadcom-dnx.swi

Note: This PR also adds support for Broadcom SAI 5.0 (based on 1.8 SAI ) for DNX based platform + changes in platform x86_64-arista_7280cr3_32p4 bcm config files and platform_env.conf files

Grouping delayed services under a target for config reload checks (#7846)
#### Why I did it
Create a target for delayed service timers. Few services in sonic have delayed to speed up the bring up of the system and essential services. However there is no way to track when they start. This will be a problem when executing config reload as config reload expects all services to be up. Hence grouped all the timers that trigger the delayed services under one target so that they could be tracked in 'config reload' command

#### How I did it
Created delay.target service and add created dependency on the delayed targets.

[Kubernetes]: The kube server could be used as http-proxy for docker (#7469)
Why I did it
The SONiC switches get their docker images from local repo, populated during install with container images pre-built into SONiC FW. With the introduction of kubernetes, new docker images available in remote repo could be deployed. This requires dockerd to be able to pull images from remote repo.

Depending on the Switch network domain & config, it may or may not be able to reach the remote repo. In the case where remote repo is unreachable, we could potentially make Kubernetes server to also act as http-proxy.

How I did it
When admin explicitly enables, the kubernetes-server could be configured as docker-proxy. But any update to docker-proxy has to be via service-conf file environment variable, implying a "service restart docker" is required. But restart of dockerd is vey expensive, as it would restarts all dockers, including database docker.

To avoid dockerd restart, pre-configure an http_proxy using an unused IP. When k8s server is enabled to act as http-proxy, an IP table entry would be created to direct all traffic to the configured-unused-proxy-ip to the kubernetes-master IP. This way any update to Kubernetes master config would be just manipulating IPTables, which will be transparent to all modules, until dockerd needs to download from remote repo.

How to verify it
Configure a switch such that image repo is unreachable
Pre-configure dockerd with http_proxy.conf using an unused IP (e.g. 172.16.1.1)
Update ctrmgrd.service to invoke ctrmgrd.py with "-p" option.
Configure a k8s server, and deploy an image for feature with set_owner="kube"
Check if switch could successfully download the image or not.

[Yang][cfggen] update sonic-cfggen to generate config_db from Yang data (#7712)
Why I did it
This PR adds changes in sonic-config-engine to consume configuration data in SONiC Yang schema and generate config_db entries

How I did it
Add a new file sonic_yang_cfg_generator .
This file has the functions to

parse yang data json and convert them in config_db json format.
Validate the converted config_db entries to make sure all the dependencies and constraints are met.
Add a new option -Y to the sonic-cfggen command for this purpose

Add unit tests

This capability is support only in sonic-config-engine Python3 package only
