Branch: refs/heads/fix-thread-pmtud-race Home: https://github.com/kronosnet/kronosnet Commit: 0f2930b9a703803e67e051a160a2c250991dcb40 https://github.com/kronosnet/kronosnet/commit/0f2930b9a703803e67e051a160a2c… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2026-05-15 (Fri, 15 May 2026) Changed paths: M libknet/threads_pmtud.c Log Message: ----------- libknet: force PMTUD rerun after reschedule interruption When PMTUD is interrupted by a reschedule request (returns EDEADLK), some links may have been checked while others were skipped. The next iteration uses the interval timer to decide which links to check, which means recently-checked links are skipped even if they need a new PMTUD run (e.g., after reconnection following onwire protocol upgrade). Fix by setting pmtud_forcerun=1 when the PMTUD thread detects it was interrupted (errno == EDEADLK). This ensures the next iteration force-runs PMTUD on all links regardless of the interval timer, completing discovery on interrupted and skipped links. This approach respects the 2018 commit d2a6344f design by setting forcerun in the PMTUD thread itself (after the interrupted iteration completes) rather than in _pmtud_reschedule() or its callers, avoiding the lock fighting and scheduling issues that commit addressed.

Di Nitto <fdinitto(a)redhat.com> Date: 2026-05-15 (Fri, 15 May 2026) Changed paths: M libknet/tests/fun_onwire_upgrade.c Log Message: ----------- tests: fix race condition in fun_onwire_upgrade test Add proper locking in upgrade_onwire_max_ver() to prevent race between test modifications of onwire_min_ver/onwire_max_ver and RX threads reading these values. RX threads hold global_rwlock during packet processing and check version fields without explicit synchronization, causing flaky test failures on FreeBSD when RX threads see stale values.

Branch: refs/heads/libnozzle-fixes Home: https://github.com/kronosnet/kronosnet Commit: 8c1dc621fb2c5ac334de0a32c4a66d9949d1edc6 https://github.com/kronosnet/kronosnet/commit/8c1dc621fb2c5ac334de0a32c4a66… Author: Fabio M. Di Nitto <fdinitto(a)redhat.com> Date: 2026-05-14 (Thu, 14 May 2026) Changed paths: M libnozzle/Makefile.am M libnozzle/internals.h M libnozzle/libnozzle.c A libnozzle/libnozzle_bsd.c A libnozzle/libnozzle_linux.c A libnozzle/libnozzle_solaris.c Log Message: ----------- libnozzle: refactor platform-specific code into dedicated files Split platform-specific implementation from libnozzle.c into dedicated files: libnozzle_linux.c, libnozzle_bsd.c, libnozzle_solaris.c. Introduce platform abstraction layer with typedefs and macros in internals.h: - nozzle_ifreq: Platform-specific ifreq structure type - NOZZLE_SOCKET_DOMAIN: Socket domain for ioctl fd (AF_LOCAL on BSD) - NOZZLE_IOCTL_FD: File descriptor for ioctl operations - NOZZLE_SET_MTU: Platform-specific MTU ioctl command - NOZZLE_IPV6_IS_SECONDARY(domain): IPv6 secondary interface check This eliminates all platform-specific #ifdef blocks from libnozzle.c, improving code organization and readability. Platform differences are now documented in a single location (internals.h and platform-specific files) rather than scattered throughout the main code. Signed-off-by: Fabio M.

Add _determine_family(), _validate_prefix(), _ipv4_prefix_to_netmask(), and _ipv6_prefix_to_mask() to internals.c/h. Include netinet/in.h in both files for struct in6_addr definition.

Eliminates ~80 lines of duplication. Signed-off-by: Fabio M.
