…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

#### 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: root@sonic:~# cat /var/log/syslog | grep "sonic.*kernel:" | head -n 3 2025 Nov 4 05:15:14.918946 sonic NOTICE kernel: [ 0.000000] Linux version 6.12.41+deb13-sonic-amd64 (debian-kernel@lists.debian.org) (x86_64-linux-gnu-gcc-14 (Debian 14.2.0-19) 14.2.0, GNU ld (GNU Binutils for Debian) 2.44) #1 SMP PREEMPT_DYNAMIC Debian 6.12.41-1 (2025-08-12) 2025 Nov 4 05:15:14.919533 sonic INFO kernel: [ 0.000000] Command line: BOOT_IMAGE=/image-trixie.0-dirty-20251102.122837/boot/vmlinuz-6.12.41+deb13-sonic-amd64 root=UUID=ac0b6826-f8a3-461f-a8ff-701df60d90b6 rw console=tty0 console=ttyS0,115200n8 quiet processor.max_cstate=1 intel_idle.max_cstate=0 net.ifnames=0 biosdevname=0 loop=image-trixie.0-dirty-20251102.122837/fs.squashfs loopfstype=squashfs apparmor=1 security=apparmor varlog_size=4096 usbcore.autosuspend=-1 intel_iommu=off modprobe.blacklist=gpio_ich,i2c-ismt,i2c_ismt,i2c-i801,i2c_i801 crashkernel=0M-2G:256M,2G-4G:320M,4G-8G:384M,8G-:448M acpi_no_watchdog 2025 Nov 4 05:15:14.919536 sonic INFO kernel: [ 0.000000] BIOS-provided physical RAM map: root@sonic:~# cat /var/log/syslog | grep "sonic.*kernel:" | tail -n 3 2025 Nov 4 05:17:26.831607 sonic WARNING kernel: [ 143.527486] PDDF_LED set_status_led: Set [FANTRAY_LED;1] color[green] 2025 Nov 4 05:17:26.912442 sonic WARNING kernel: [ 143.607086] PDDF_LED set_status_led: Set [FANTRAY_LED;2] color[green] 2025 Nov 4 05:20:32.499634 sonic WARNING kernel: [ 329.195319] PDDF_LED set_status_led: Set [SYS_LED;0] color[amber] root@sonic:~# Signed-off-by: Ramasamy Chandramouli <rachandr@celestica.com> Co-authored-by: Ramasamy Chandramouli <rachandr@celestica.com>

…net#25643) * [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 Signed-off-by: Rustiqly <rustiqly@users.noreply.github.com> * Address Copilot review: fix 17 bugs in build analysis scripts - Use free -m with division instead of free -g to avoid rounding (#1) - Add = and ?= to Makefile dependency regex patterns (#2, #7) - CPU calculation now uses /proc/stat delta (two reads) (#3, #14) - Fix misleading 'critical path estimate' comment (#4) - Fix parallelism timeline comment (60s not 10s) (#5) - Include after-relationship packages in fan stats (#6) - Guard disk I/O division by zero when INTERVAL<=1 (#8) - Remove unused elapsed_line variable (#9) - Remove redundant LIBSWSSCOMMON_DBG check (#10) - Remove active_make_jobs from CSV header comment (#11) - Wire up _RDEPENDS parsing to build reverse deps (#12) - Remove unnecessary 'if v' filter on rdeps JSON (#13) - Remove unused REPORT_FORMAT parameter (#15) - Add cycle detection to critical path algorithm (#16) - Add execute permission check for companion scripts (#17) Signed-off-by: Rustiqly <rustiqly@users.noreply.github.com> --------- Signed-off-by: Rustiqly <rustiqly@users.noreply.github.com> Co-authored-by: Rustiqly <rustiqly@users.noreply.github.com>

…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. Core was generated by `/usr/lib/systemd/systemd-udevd --daemon --resolve-names=never'. Program terminated with signal SIGABRT, Aborted. #0 0x00007f29fe7f695c in ??

() - 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 Signed-off-by: Hemanth Kumar Tirupati <tirupatihemanthkumar@gmail.com>

#### Why I did it Kdump takes a long time to complete because makedumpfile is version 1.7.6 which is not compatible with 6.12 ([ref](https://github.com/makedumpfile/makedumpfile/releases/tag/1.7.6)). It incorrectly classifies free pages as in use by kernel, resulting in extremely large core dump file and taking a long time to generate. On 6.1, makedumpfile is 1.7.2.

…dating udevd rules (sonic-net#26573) <!-- Please make sure you've read and understood our contributing guidelines: https://github.com/Azure/SONiC/blob/gh-pages/CONTRIBUTING.md failure_prs.log skip_prs.log Make sure all your commits include a signature generated with `git commit -s` ** If this is a bug fix, make sure your description includes "fixes #xxxx", or "closes #xxxx" or "resolves #xxxx" Please provide the following information: --> #### 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. ``` Core was generated by `/usr/lib/systemd/systemd-udevd --daemon --resolve-names=never'.

() ``` #### 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 <!-- If PR needs to be backported, then the PR must be tested against the base branch and the earliest backport release branch and provide tested image version on these two branches. For example, if the PR is requested for master, 202211 and 202012, then the requester needs to provide test results on master and 202012. --> - 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 <X> (systemd udevd is PID <Y>) - 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 Signed-off-by: Sonic Build Admin <sonicbld@microsoft.com>
