Hi @alexrallen, can you update your branch to the current contents of my branch? That'll get rid of the merge conflicts.

You can use the version of src/sonic-linux-kernel that is in my branch; it has all of the changes.

…net#10291)

#### Why I did it

Fix issue: Non compliant leaf list in config_db schema: sonic-net#9801

#### How I did it

The basic flow of DPB is like:
1.	Transfer config db json value to YANG json value, name it “yangIn”
2.	Validate “yangIn” by libyang
3.	Generate a YANG json value to represent the target configuration, name it “yangTarget”
4.	Do diff between “yangIn” and “yangTarget”
5.	Apply the diff to CONFIG DB json and save it back to DB
 
The fix:
•	For step #1, If value of a leaf-list field string type, transfer it to a list by splitting it with “,” the purpose here is to make step#2 happy. We also need to save <table_name>.<key>.<field_name> to a set named “leaf_list_with_string_value_set”.
•	For step#5, loop “leaf_list_with_string_value_set” and change those fields back to a string.


#### How to verify it

1. Manual test
2. Changed sample config DB and unit test passed

…kernel 6.1 and bookworm (sonic-net#16954)

* sonic-platform-modules-cel: broadcom: adapt for kernel 6.1 and bookworm

The i2c_driver->remove API declaration has been updated to return void instead
of int, as part of cleanup patches in 6.1. More details can be referred from
here: [1]. Update the remove API definition in the modules accordingly and
cleanup variables that go unused from the remove API.

Update python build commands for bookworm. The packaging based on calling
setup.py is deprecated and using build module/pip utility is the recommended
method for python packaging/installation. Further details can be referred to
from here: [2], [3]. The build module is picky about the package information file,
which needs to be either setup.py or pyproject.toml.

Additionally, fix formatting inconsistencies in debian/changelog reported by
`dh_installchangelogs` during the build.

Tested the changes by compiling the changes as below:

    make sonic-slave-bash NOBUSTER=1 NOBULLSEYE=1
    sudo dpkg -i target/debs/bookworm/linux-headers-6.1.0-11-2-*.deb
    cd platform/broadcom/sonic-platform-modules-cel
    KVERSION=6.1.0-11-2-amd64 dpkg-buildpackage

Also verified the python scripts under the sonic-platform-modules-cel with
pyflakes to ensure no new errors are flagged (with exception of unused modules).

#### Why I did it

Dropping control character (message sent when XSUB connects to XPUB as part of ZMQ Proxy setup to notify that subscription has been made) in do capture has been flaky since control character is not guaranteed to be the first message sent if there are events (like event-down-ctr) being published to XSUB.

Scenarios

1) Control character is sent and is first message when starting capture service

`eventd#eventd#eventd: :- heartbeat_ctrl: Set heartbeat_ctrl pause=1`
`eventd#eventd#eventd: :- do_capture: Received subscription message when XSUB connects to XPUB`

2) Events like event-down ctr is sent before control character

`eventd#eventd#eventd: :- run: Dropping Message: 22 serialization::archive 18 17 sonic-events-host`
`eventd#eventd#eventd: :- run: Dropping Message: 22 serialization::archive 18 0 0 4 0 0 0 1 d 103 {"sonic-events-host:event-stopped-ctr":{"ctr_name":"EVENTD","timestamp":"2024-08-27T00:02:51.407518Z"}} 1 r 36 3357542f-bae1-458f-a804-660e620d21f5 1 s 1 9 1 t 19 1724716971407591080`
`heartbeat_ctrl: Set heartbeat_ctrl pause=1`
`do_capture: Received subscription message when XSUB connects to XPUB`

3) Control character is not sent at all

`eventd#eventd#eventd: :- heartbeat_ctrl: Set heartbeat_ctrl pause=1`

4) Control character is delayed and not caught when starting capture service, but is then caught after causing deserialize error.

`do_capture: Receiving event from source: 22 serialization::archive 18 17 sonic-events-host, will read second part of event`
`deserialize: deserialize Failed: input stream errorstr[0:64]:(#1) data type: std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&`
`zmq_read_part: Failed to deserialize part rc=-2`
`zmq_read_part: last:errno=11`
`zmq_message_read: Failure to read part1 rc=-2`
`zmq_message_read: last:errno=11`

We can cover these scenarios by just dropping the control character inside zmq_message_read as part of events_common in swsscommon (different PR). In this PR we will remove such handling logic and make sure that empty events that will be sent by control character are ignored.

#### Why I did it

Dropping control character (message sent when XSUB connects to XPUB as part of ZMQ Proxy setup to notify that subscription has been made) in do capture has been flaky since control character is not guaranteed to be the first message sent if there are events (like event-down-ctr) being published to XSUB.

Scenarios

1) Control character is sent and is first message when starting capture service

`eventd#eventd#eventd: :- heartbeat_ctrl: Set heartbeat_ctrl pause=1`
`eventd#eventd#eventd: :- do_capture: Received subscription message when XSUB connects to XPUB`

2) Events like event-down ctr is sent before control character

`eventd#eventd#eventd: :- run: Dropping Message: 22 serialization::archive 18 17 sonic-events-host`
`eventd#eventd#eventd: :- run: Dropping Message: 22 serialization::archive 18 0 0 4 0 0 0 1 d 103 {"sonic-events-host:event-stopped-ctr":{"ctr_name":"EVENTD","timestamp":"2024-08-27T00:02:51.407518Z"}} 1 r 36 3357542f-bae1-458f-a804-660e620d21f5 1 s 1 9 1 t 19 1724716971407591080`
`heartbeat_ctrl: Set heartbeat_ctrl pause=1`
`do_capture: Received subscription message when XSUB connects to XPUB`

3) Control character is not sent at all

`eventd#eventd#eventd: :- heartbeat_ctrl: Set heartbeat_ctrl pause=1`

4) Control character is delayed and not caught when starting capture service, but is then caught after causing deserialize error.

`do_capture: Receiving event from source: 22 serialization::archive 18 17 sonic-events-host, will read second part of event`
`deserialize: deserialize Failed: input stream errorstr[0:64]:(#1) data type: std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&`
`zmq_read_part: Failed to deserialize part rc=-2`
`zmq_read_part: last:errno=11`
`zmq_message_read: Failure to read part1 rc=-2`
`zmq_message_read: last:errno=11`

We can cover these scenarios by just dropping the control character inside zmq_message_read as part of events_common in swsscommon (different PR). In this PR we will remove such handling logic and make sure that empty events that will be sent by control character are ignored.

…logs (#56)

The `imklog` plugin of rsyslog collects the kernel logs from `/dev/kmsg` and
enqueues it to the syslog. With `CONFIG_PRINTK_TIME` the kernel messages are by
default prefixed with the elapsed time since boot. The `imklog` plugin parsing
these messages have a few options such as to keep the timestamps as such or to
interpret and adjust the syslog's reported time accordingly.

The rsylog release `8.2312.0` has fixes in interpreting these timestamps,
leading to the change in behavior observed in sonic-net#24386.

  https://salsa.debian.org/debian/rsyslog/-/blob/debian/8.2504.0-1/ChangeLog?ref_type=tags#L619

To restore the earlier behavior or retaining the kernel reported elapsed time,
disable `KlogParseKernelTimestamp` as this leads to removal of timestamp from
kernel messages and enable `KlogKeepKernelTimestamp` explicitly. The later is
required as the default is now to discard the kernel timestamp.

With this change, the logs retain the kernel timestamp:

The `imklog` plugin of rsyslog collects the kernel logs from `/dev/kmsg` and
enqueues it to the syslog. With `CONFIG_PRINTK_TIME` the kernel messages are by
default prefixed with the elapsed time since boot. The `imklog` plugin parsing
these messages have a few options such as to keep the timestamps as such or to
interpret and adjust the syslog's reported time accordingly.

The rsylog release `8.2312.0` has fixes in interpreting these timestamps,
leading to the change in behavior observed in sonic-net#24386.

  https://salsa.debian.org/debian/rsyslog/-/blob/debian/8.2504.0-1/ChangeLog?ref_type=tags#L619

To restore the earlier behavior or retaining the kernel reported elapsed time,
disable `KlogParseKernelTimestamp` as this leads to removal of timestamp from
kernel messages and enable `KlogKeepKernelTimestamp` explicitly. The later is
required as the default is now to discard the kernel timestamp.

With this change, the logs retain the kernel timestamp:

#### Why I did it
If one python wheel is already installed inside slave container, it will not install again. Below is a sample log:
```
sed: -e expression #1, char 11: extra characters after command
WARNING: The directory '/var/user/.cache/pip' or its parent directory is not owned or is not writable by the current user. The cache has been disabled. Check the permissions and owner of that directory. If executing pip with sudo, you should use sudo's -H flag.

sonic-yang-models is already installed with the same version as the provided wheel. Use --force-reinstall to force an installation of the wheel.
WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager, possibly rendering your system unusable.It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv. Use the --root-user-action option if you know what you are doing and want to suppress this warning.

```
 However, we expect to reinstall the python wheel for target `$(PYTHON_WHEELS_PATH)/%-install`

##### Work item tracking
- Microsoft ADO **(number only)**:

#### How I did it
Update slave.mk to enasure force install the python wheel.

#### How to verify it
After this change, local build will successfully force install the python wheel. See new logs:

…logs

The `imklog` plugin of rsyslog collects the kernel logs from `/dev/kmsg` and
enqueues it to the syslog. With `CONFIG_PRINTK_TIME` the kernel messages are by
default prefixed with the elapsed time since boot. The `imklog` plugin parsing
these messages have a few options such as to keep the timestamps as such or to
interpret and adjust the syslog's reported time accordingly.

The rsylog release `8.2312.0` has fixes in interpreting these timestamps,
leading to the change in behavior observed in sonic-net#24386.

  https://salsa.debian.org/debian/rsyslog/-/blob/debian/8.2504.0-1/ChangeLog?ref_type=tags#L619

To restore the earlier behavior or retaining the kernel reported elapsed time,
disable `KlogParseKernelTimestamp` as this leads to removal of timestamp from
kernel messages and enable `KlogKeepKernelTimestamp` explicitly. The later is
required as the default is now to discard the kernel timestamp.

With this change, the logs retain the kernel timestamp:

* [build] Add build timing report and dependency analysis tools

Add three scripts for build performance instrumentation:

- scripts/build-timing-report.sh: Parse per-package timing from build
  logs (HEADER/FOOTER timestamps), generate sorted duration table,
  phase breakdown, parallelism timeline, and CSV export.

- scripts/build-dep-graph.py: Parse rules/*.mk dependency graph,
  compute critical path, fan-out/fan-in bottleneck analysis, and
  generate DOT/JSON output for visualization.

- scripts/build-resource-monitor.sh: Sample CPU, memory, disk I/O,
  and Docker container count during builds for resource utilization
  analysis.

Add "make build-report" target to slave.mk that runs the timing
report and dependency analysis after a build completes.

Example output from a VS build on 24-core/30GB machine:
- 210 packages built in 53m wall time (173m CPU)
- Max concurrency: 5 (with SONIC_CONFIG_BUILD_JOBS=4)
- Critical path: 14 packages deep (libnl -> libswsscommon -> utilities)
- Top bottleneck: LIBSWSSCOMMON with 48 downstream dependents

…dating udevd rules (sonic-net#26343)

- Why I did it
On SONiC SmartSwitch platforms with DPUs, systemd-udevd crashes with SIGABRT on every reboot when DPU firmware initialization is slow. During the initramfs boot phase, a standalone systemd-udevd daemon is started to handle device discovery. If DPU firmware takes longer than the 60-second udevadm settle timeout (BlueField-3 DPUs can take 120 seconds each in the failure case when they are stuck), the initramfs cannot stop this udevd before switch_root. The stale process survives into the real system but is never chrooted into the overlayfs root, leaving it with a broken filesystem view. When dpu-udev-manager.sh writes udev rules, the stale udevd detects the change and crashes on an assertion in systemd's chase() path resolution (assert(path_is_absolute(p)) at chase.c:648), because dir_fd_is_root() returns false for a process whose root still points to the initramfs rootfs rather than the overlayfs.

This triggers a systemd issue : systemd/systemd#29559 which maintainers doesn't consider as a bug from systemd side. Raising this fix for our usecase.

- How I did it
Added a kill_stale_udevd() function to dpu-udev-manager.sh that runs before writing the udev rules. It identifies the systemd-managed udevd PID via systemctl show, then kills any other systemd-udevd --daemon process that doesn't match -- these are leftover initramfs instances. If no stale process exists (e.g. DPUs are healthy and the initramfs udevd exited cleanly), the function is a no-op.

- How to verify it
Deploy the image on a SmartSwitch with DPUs in a state where firmware initialization times out (>60s per DPU) by stopping image installation before firmware install step
Reboot the switch
Verify no new systemd-udevd coredumps in /var/core/
Verify the stale process was killed: journalctl -b 0 | grep dpu-udev-manager should show killing stale initramfs udevd PID (systemd udevd is PID )
Verify systemd-udevd.service is healthy: systemctl status systemd-udevd should show active (running)
Verify DPU udev rules were written: cat /etc/udev/rules.d/92-midplane-intf.rules should contain the DPU interface naming rules
