A bug crept into 2.13.0 which caused the system call input arguments to be recorded on return from system call rather than the output arguments. This fix was in the master branch of lttng-modules, but was not cherry-picked into the 2.13 stable branch. This missing backport went unnoticed through our CI integration because the relevant kernel tracer tests were not part of lttng-tools default test suite: "make check". This is now fixed in the lttng-tools project. This release also contains commits needed to trace the 5.17 kernels (currently at v5.17-rc7). Users of lttng-modules 2.13.0 and 2.13.1 should upgrade to 2.13.2 if they want to gather useful output arguments on return from system call into their trace, rather than an extra copy of the system call input arguments. Thanks, Mathieu Changelog: 2022-03-07 (National Cereal Day) LTTng modules 2.13.2 * Fix: incorrect in/out direction for syscall exit * fix: net: socket: rename SKB_DROP_REASON_SOCKET_FILTER (v5.17) * fix: net: skb: introduce kfree_skb_reason() (v5.17) * fix: random: rather than entropy_store abstraction, use global (v5.17) * fix: btrfs: pass fs_info to trace_btrfs_transaction_commit (v5.17) * fix: mm: compaction: fix the migration stats in trace_mm_compaction_migratepages() (v5.17) * fix: block: remove the ->rq_disk field in struct request (v5.17) * fix: block: remove GENHD_FL_SUPPRESS_PARTITION_INFO (v5.17) * Copyright ownership transfer Project website: https://lttng.org Documentation: https://lttng.org/docs Download link: https://lttng.org/download -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com _______________________________________________ lttng-dev mailing list lttng-dev@lists.lttng.org https://lists.lttng.org/cgi-bin/mailman/listinfo/lttng-dev
