#### Why I did it
Avoid 'sscanf()' for number conversions. Its use can lead to undefined behavior, slow processing, and integer overflows. Instead prefer the 'strto*()' family of functions.
#### How I did it
replace sscanf with strtol
#### How to verify it
Manual test
- 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.
Why I did it
Current docker-sonic-mgmt build is broken. So below are two fixes which can help in mitigating the same.
PYAML - Download a specific version in python2 as after https://pypi.org/project/pyaml/23.5.5/ there was support only for python3. This update happened on May 5th. And consequently all daily builds after this changes https://dev.azure.com/mssonic/build/_build/results?buildId=266733&view=results (starting build to break) kept failing
Azure-CLI - this can be downloaded by apt-get repository. So modify as an improvement.

Microsoft ADO (number only): [Build] fix docker-sonic-mgmt build #15567
How I did it
By manually checking the release notes of pyaml and install azure-cli in newly installed docker container using apt-get
How to verify it
You can run below commands to validate:
make configure PLATFORM=generic
make target/docker-sonic-mgmt.gz
Second line would fail without the commit.

Added support data for fabric monitoring in CONFIG_DB
The CONFIG_DB now has the FABRIC_MONITOR|FABRIC_MONITOR_DATA table for default value for fabric port monitoring. An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_MONITOR|FABRIC_MONITOR_DATA"
{'monErrThreshCrcCells': '1', 'monErrThreshRxCells': '61035156', 'monPollThreshIsolation': '1', 'monPollThreshRecovery': '8'}
The CONFIG_DB now also has a table for each fabric port for its isolate status.
An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_PORT|Fabric20"
{'alias': 'Fabric20', 'isolateStatus': 'False', 'lanes': '20'}
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.

Why I did it
sonic-mgmt is failing tests due to invalid test data in platform.json
Fwutil is upset the chassis name in the platform_component.json of the 7060CX-32S
How I did it
Fixed the aforementioned issues
* 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.
