Why I did it
Sharing the storage of syncd with other proprietary application extensions allows them to communicate with syncd in differnt ways.
If one container wants to pass some information to syncd then shared storage can be used. However, today the shared storage isn't cleaned on restarts making it possible for syncd to read out-of-date information generated in the past.
NOTE: No plans to use it for standard SONIC dockers and we are working on removing the SDK dependency from PMON docker
How I did it
Implemented new service to clean the shared storage.
How to verify it
Do reboot/fast-reboot/warm-reboot/config-reload/systemctl restart swss and verify /tmp/ is cleaned after each restart in syncd container.

- Why I did it
Add support for static DNS configuration. According to sonic-net/SONiC#1262 HLD.
- How I did it
Add a new resolv-config.service that is responsible for transferring configuration from Config DB into /etc/resolv.conf file that is consumed by various subsystems in Linux to resolve domain names into IP addresses.
- How to verify it
Run the image compilation. Each component related to the static DNS feature is covered with the unit tests.
Run sonic-mgmt tests. Static DNS feature will be covered with the system tests.
Install the image and run manual tests.
This reverts commit 02b17839c3.
Reverts #14933
The earlier commit caused a race condition that particularly broke cross branch warm upgrade.
Issue happens when db_migrator is still migrating the DB and finalizer is checking DB for list of components to reconcile.
If migration is not complete, finalizer get an empty list to wait for. Due to this, finalizer concludes warmboot (deletes system wide warmboot flag) and cause all the services to do cold restart.

* Re-add 127.0.0.1/8 when bringing down the interfaces
With #5353, 127.0.0.1/16 was added to the lo interface, and then
127.0.0.1/8 was removed. However, when bringing down the lo interface,
like during a config reload, 127.0.0.1/16 gets removed, but 127.0.0.1/8
isn't added back to the interface. This means that there's a period of
time where 127.0.0.1 is not available at all, and services that need to
connect to 127.0.01 (such as for redis DB) will fail.
To fix this, when going down, add 127.0.0.1/8. Add this address before
the existing configuration gets removed, so that 127.0.0.1 is available
at all times.
Note that running `ifdown lo` doesn't actually bring down the loopback
interface; the interface always stays "physically" up.

Why I did it
Fix the issue where db_migrator is called before DB is loaded w/ config. This leads to db_migrator:
Not finding anything, and resumes to incorrectly migrate every missing config
This is not expected. migration should happen after the old config is loaded and only new schema changes need migration.
Since DB does not have anything when migrator is called, db_migrator fails when some APIs return None.
The reason for incorrect call is that:
database service starts db_migrator as part of startup sequence.
config-setup service loads data from old-config/minigraph. However, since it has Requires=database.service.
Hence, config-setup starts only when database service is started. And database service is started when db_migrator is completed.
Fixed by:
Check if this is first time boot by checking pending_config_migration flag.
If pending_config_migration is enabled, then do not call db_migrator as part of database service startup.
Let database service start which triggers config-setup service to start.
Now call db_migrator after when config-setup service loads old-config/minigraph

Some devices running SONiC have a small storage device (2G and 4G mainly)
The SONiC image growth over time has made it impossible to install
2 images on a single device.
Some mitigations have been implemented in the past for some devices but
there is a need to do more.
One such mitigation is `docker_inram` which creates a `tmpfs` and
extracts `dockerfs.tar.gz` in it.
This all happens in the SONiC initramfs and by ensuring the installation
process does not extract `dockerfs.tar.gz` on the flash but keep the file as is.
This mitigation does a tradeoff by using more RAM to reduce the disk footprint.
It however creates new issues for devices with 4G of system memory since
the extracted `dockerfs.tar.gz` nears the 1.6G.
Considering debian upgrades (with dual base images) and the continuous
stream of features this is only going to get bigger.
This change introduces an alternative to the `tmpfs` by allowing a system
to extract the `dockerfs.tar.gz` inside a `zram` device thus bringing
compression in play at the detriment of performance.
Introduce 2 new optional kernel parameters to be consumed by SONiC initramfs.
- `docker_inram_size` which represent the max physical size of the
`zram` or `tmpfs` volume (defaults to DOCKER_RAMFS_SIZE)
- `docker_inram_algo` which is the method to use to extract the
`dockerfs.tar.gz` (defaults to `tmpfs`)
other values are considered to be compression algorithm for `zram`
(e.g `zstd`, `zlo-rle`, `lz4`)
Refactored the logic to mount the docker fs in the SONiC initramfs under
the `union-mount` script.
Moved the code into a function to make it cleaner and separated the
inram volume creation and docker extraction.
On Arista platform with a flash smaller or equal to 4GB set
`docker_inram_algo` to `zstd` which produces the best compression ratio
at the detriment of a slower write performance and a similar read
performance to other `zram` compression algorithms.
Enable docker_inram for all systems with 4GB or less of flash.
This is mandatory to allow these systems to store 2 SONiC images.
This change also fixes the missing docker_inram attribute when
installing a new image from SONiC.
Because the SWI image can ship with additional kernel parameters within
such as `sonic_fips=` this lead to a conflict.
To prevent the conflict, the extra kernel parameters from the SWI are
now stored in the file `kernel-cmdline-append` which isn't used anywhere.

Support for SONIC chassis isolation using TSA and un-isolation using TSB from supervisor module
Work item tracking
Microsoft ADO (number only): 17826134
How I did it
When TSA is run on the supervisor, it triggers TSA on each of the linecards using the secure rexec infrastructure introduced in sonic-net/sonic-utilities#2701. User password is requested to allow secure login to linecards through ssh, before execution of TSA/TSB on the linecards
TSA of the chassis withdraws routes from all the external BGP neighbors on each linecard, in order to isolate the entire chassis. No route withdrawal is done from the internal BGP sessions between the linecards to prevent transient drops during internal route deletion. With these changes, complete isolation of a single linecard using TSA will not be possible (a separate CLI/script option will be introduced at a later time to achieve this)
Changes also include no-stats option with TSC for quick retrieval of the current system isolation state

chassis-packet: missing arp entries for static routes causing high orchagent cpu usage
It is observed that some sonic-mgmt test case calls sonic-clear arp, which clears the static arp entries as well. Orchagent or arp_update process does not try to resolve the missing arp entries after clear.
How I did it
arp_update should resolve the missing arp/ndp static route
entries. Added code to check for missing entries and try ping if any
found to resolve it.
How to verify it
After boot or config reload, check ipv4 and ipv4 neigh entries to make sure all static route entries are present
manual validation:
Use sonic-clear arp and sonic-clear ndp to clear all neighbor entries
run arp_update
Check for neigh entries. All entries should be present.

To solve an issue with upgrade with fast-reboot including FW upgrade which has been introduced since moving to fast-reboot over warm-reboot infrastructure.
As well, this introduces fast-reboot finalizing logic to determine fast-reboot is done.
- How I did it
Added logic to finalize-warmboot script to handle fast-reboot as well, this makes sense as using fast-reboot over warm-reboot this script will be invoked. The script will clear fast-reboot entry from state-db instead of previous implementation that relied on timer. The timer could expire in some scenarios between fast-reboot finished causing fallback to cold-reboot and possible crashes.
As well this PR updates all services/scripts reading fast-reboot state-db entry to look for the updated value representing fast-reboot is active.

Add Secure Boot support to SONiC OS.
Secure Boot (SB) is a verification mechanism for ensuring that code launched by a computer's UEFI firmware is trusted. It is designed to protect a system against malicious code being loaded and executed early in the boot process before the operating system has been loaded.
- How I did it
Added a signing process to sign the following components:
shim, grub, Linux kernel, and kernel modules when doing the build, and when feature is enabled in build time according to the HLD explanations (the feature is disabled by default).
- How to verify it
There are self-verifications of each boot component when building the image, in addition, there is an existing end-to-end test in sonic-mgmt repo that checks that the boot succeeds when loading a secure system (details below).
How to build a sonic image with secure boot feature: (more description in HLD)
Required to use the following build flags from rules/config:
SECURE_UPGRADE_MODE="dev"
SECURE_UPGRADE_DEV_SIGNING_KEY="/path/to/private/key.pem"
SECURE_UPGRADE_DEV_SIGNING_CERT="/path/to/cert/key.pem"
After setting those flags should build the sonic-buildimage.
Before installing the image, should prepared the setup (switch device) with the follow:
check that the device support UEFI
stored pub keys in UEFI DB
enabled Secure Boot flag in UEFI
How to run a test that verify the Secure Boot flow:
The existing test "test_upgrade_path" under "sonic-mgmt/tests/upgrade_path/test_upgrade_path", is enough to validate proper boot
You need to specify the following arguments:
Base_image_list your_secure_image
Taget_image_list your_second_secure_image
Upgrade_type cold
And run the test, basically the test will install the base image given in the parameter and then upgrade to target image by doing cold reboot and validates all the services are up and working correctly
Fixes#13568

Add new attribute "mux_tunnel_ingress_acl" to SYSTEM_DEFAULTS table
- How to verify it
check that new attribute exists in redis:
admin@sonic:~$ redis-cli -n 4
127.0.0.1:6379[4]> HGETALL SYSTEM_DEFAULTS|mux_tunnel_ingress_acl
1."state"
2."false"

Fixe #12047. After the c++ implementation of the sonic-db-cli, sonic-db-cli PING command tries to initialize the global database for all instances database starting. If all instance database-config.json are not ready yet. it will crash and generate core file. PR sonic-net/sonic-swss-common#701 only fix the crash and the process abortion.

Why I did it
Some products might experience an occasional IO failure in the communication between CPU and SSD.
Based on some research it could be attributable to some device not handling ATA NCQ (Native Command Queue).
This issue currently affect 4 products:
DCS-7170-32C*
DCS-7170-64C
DCS-7060DX4-32
DCS-7260CX3-64
How I did it
This change disable NCQ on the affected drive for a small set of products.
How to verify it
When the fix is applied, these 2 patterns can be found in the dmesg.

Which release branch to backport (provide reason below if selected)
Go's runtime (and dockerd inherits this) uses own DNS resolver implementation by default on Linux.
It has been observed that there are some DNS resolution issues when executing ```docker pull``` after first boot.
Consider the following script:
```
admin@r-boxer-sw01:~$ while :; do date; cat /etc/resolv.conf; ping -c 1 harbor.mellanox.com; docker pull harbor.mellanox.com/sonic/cpu-report:1.0.0 ; sleep 1; done

While /etc/resolv.conf has the correct content and ping (and any other utility that uses libc's DNS resolution implementation) works correctly
docker is unable to resolve the hostname and falls back to default [::1]:53. This started to happen after PR https://github.com/sonic-net/sonic-buildimage/pull/13516 has been merged.
As you can see from the log, dockerd is able to pick up the correct /etc/resolv.conf only after 5 sec since first try. This seems to be somehow related to the logic in Go's DNS resolver
https://github.com/golang/go/blob/master/src/net/dnsclient_unix.go#L385.
There have been issues like that reported in docker like:
- https://github.com/docker/cli/issues/2299
- https://github.com/docker/cli/issues/2618
- https://github.com/moby/moby/issues/22398
Since this starts to happen after inclusion of resolvconf package by
above mentioned PR and the fact I can't see any problem with that (ping,
nslookup, etc. works) the choice is made to force dockerd to use cgo
(libc) resolver.

Why I did it
backplane ports cable length need to be specified.
How I did it
separated handling for the specific port name.
Why I did it
To address error sometimes seen when running sonic-mgmt test_stress_routes.py::test_announce_withdraw_route on 720DT-48S
How I did it
Update boot0 logic to set platform specific varlog size for 720DT-48S
How to verify it
Verified that /var/log size increased and error is no longer observed when running test
Why I did it
Fix some unreliability seen on emmc device with some AMD CPUs
How I did it
Added a kernel parameter to add quirks to
It depends on a sonic-linux-kernel change to work properly but will be a no-op without it.
The quirk added is SDHCI_QUIRK2_BROKEN_HS200 used to downgrade the link speed for the eMMC.
- 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

After upgrade to brcmsai 8.1, the sdk running environment (container) recommended with mininum memory size as below
TH4/TD4(ltsw) uses 512MB
TH3 used 300MB
Helix4/TD2/TD3/TH/TH 256 MB
Base on this requirement, adjust the default syncd share memory size and set the memory size for special ACISs in platform_env.conf file for different types of Broadcom ASICs.
How I did it
Add the platform_env.conf file if none of it for broadcom platform (base on platform_asic file)
Add the 'SYNCD_SHM_SIZE' and set the value
for ltsw(TD4/TH4) devices set to 512M at least (update the platform_env.conf)
for Td2/TH2/TH devices set to 256M
for TH3 set to 300M

- Why I did it
fixes#12907
When the management interface IP address configuration changes from dynamic to static the DNS configuration (retrieved from the DHCP server) in /etc/resolv.conf remains uncleared. This leads to a DNS configuration pointing to the wrong nameserver. To make the behavior clear DNS configuration received from DHCP should be cleared.
- How I did it
Use resolvconf package for managing DNS configuration. It is capable of tracking the source of DNS configuration and puts the configuration retrieved from the DHCP servers into a separate file. This allows the implementation of DNS configuration cleanup retrieved from DHCP during networking reconfiguration.
- How to verify it
Ensure that the management interface has no static configuration.
Check that /etc/resolv.conf has DNS configuration.
Configure a static IP address on the management interface.
Verify that /etc/resolv.conf has no DNS configuration.
Remove the static IP address from the management interface.
Verify that /etc/resolv.conf has DNS configuration retrieved form DHCP server.
