Fix ASAN build clobbering packages after build on the same system by croos12 · Pull Request #13 · croos12/sonic-buildimage

Depends on:
croos12/sonic-sairedis#10
croos12/sonic-swss#6

Why I did it

ASAN-instrumented deb packages and Docker images had the same filenames as regular builds, making it impossible to build ASAN on top of a regular build without clobbering and reusing artifacts, such as swss deb and syncd deb that need to be rebuilt for ASAN. Additionally, ENABLE_ASAN was not exported during Docker image builds, so ASAN_OPTIONS were never set in supervisord.conf at runtime.

How I did it

Renamed ASAN deb targets with -asan suffix (e.g., swss-asan_1.0.0_amd64.deb) using a new _DPKG_DEB_NAME property to map dpkg output names to renamed Make targets in slave.mk.
Renamed ASAN Docker images with -asan suffix (e.g., docker-orchagent-asan.gz, docker-syncd-mlnx-asan.gz).
Added debug symbol packages (LIBSWSSCOMMON_DBG, LIBSAIREDIS_DBG, LIBSAIMETADATA_DBG) to ASAN Docker image dependencies for complete stack traces.
Removed redundant $(ENABLE_ASAN) from _DEP_FLAGS since distinct filenames now create separate cache entries.
Exported ENABLE_ASAN in the Docker image build recipe so Dockerfile.j2 can pass it through to docker-init.sh and supervisord.conf.

How to verify it

Build regular then ASAN: both artifacts coexist in target/ (docker-orchagent.gz and docker-orchagent-asan.gz).
On device inside swss container:

docker exec -it swss bash
ldd /usr/bin/orchagent | grep asan
	libasan.so.8 => /lib/x86_64-linux-gnu/libasan.so.8 (0x00007efca6d19000)
grep ASAN /usr/bin/docker-init.sh
     -a "{\"ENABLE_ASAN\":\"y\"}" \
sonic-cfggen -y /etc/sonic/sonic_version.yml -v asan
yes

Verify ASAN is active at runtime:

export ASAN_OPTIONS="detect_leaks=1:log_path=/var/log/asan/test:verbosity=2"
supervisorctl stop orchagent
/usr/bin/orchagent.sh &
sleep 5
kill -TERM $(pidof orchagent)
ls -la /var/log/asan/
test.log.5095

Pull request overview

This PR updates the SONiC build system to better support AddressSanitizer (ASAN) builds alongside regular builds by introducing ASAN-suffixed artifact naming and adjusting how debs/docker images are produced and cached.

Changes:

Rename key deb/docker outputs for ASAN builds (e.g., swss-asan, syncd-asan, docker-orchagent-asan, docker-syncd-*-asan) to avoid collisions with regular build artifacts.
Teach the dpkg deb move step to support renaming via *_DPKG_DEB_NAME, enabling “target name != dpkg output filename”.
Update several *_DEP_FLAGS definitions to drop $(ENABLE_ASAN) so dependency/cache keys align with the new artifact naming approach.

I suppose this also must be changed, we need to add extra package here swss-asan, syncd-asan target

…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 <[email protected]> * 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, sonic-net#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 (sonic-net#15) - Add cycle detection to critical path algorithm (sonic-net#16) - Add execute permission check for companion scripts (sonic-net#17) Signed-off-by: Rustiqly <[email protected]> --------- Signed-off-by: Rustiqly <[email protected]> Co-authored-by: Rustiqly <[email protected]>

…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 <[email protected]>
