- Why I did it

Inband port can be made available in PORT table. But regular port handlngs are
not applicable for Inband port.

Changes in this PR are to make LLDP to consider Inband port and to avoid regular
port handling on Inband port.

Currently the Inband interface is used for VOQ chassis systems for asic to asic communications.

- How I did it

  • Changes done in supervisor conf for LLDP to include Inband in the interface list
  • Changes done in platform common files to handle Inand port similar to how backplane port is handled

- How to verify it

  • Expose a port with name prefixed with "Inband" to SONiC via port_config.ini
  • Have an entry in the PORT table for this port with name "Inband"
  • When the system is booted, there should not be errors related to Inband interface

- Which release branch to backport (provide reason below if selected)

- Description for the changelog

Changes to avoid LLDP config on Inband interface. Since port type inband
interfaces are recycle ports (or may normal ports) used for asic-to-asic
communication, LLDP is not configured on these interfaces.

(1) Based on review comments Recyle port HLD
(sonic-net/SONiC#742) the inband port name prefix is
changed from Inband to "Ethernet-IB" similar to what we have for
Ethernet-BP (Ethernet-Backplane) in multi-asic design. Changes are done
in interface.py to handle this changed name
(2) Code review comments fix for lldpmgrd

* [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

- Fix misleading 'critical path estimate' comment (sonic-net#4)
- Fix parallelism timeline comment (60s not 10s) (sonic-net#5)
- Include after-relationship packages in fan stats (sonic-net#6)
- Guard disk I/O division by zero when INTERVAL<=1 (sonic-net#8)
- Remove unused elapsed_line variable (sonic-net#9)
- Remove redundant LIBSWSSCOMMON_DBG check (sonic-net#10)
- Remove active_make_jobs from CSV header comment (sonic-net#11)
- Wire up _RDEPENDS parsing to build reverse deps (sonic-net#12)
- Remove unnecessary 'if v' filter on rdeps JSON (sonic-net#13)
- Remove unused REPORT_FORMAT parameter (sonic-net#15)
- Add cycle detection to critical path algorithm (sonic-net#16)
- Add execute permission check for companion scripts (sonic-net#17)

…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
