This series fixes 3 different issues: - Patch1: memory leak of tracked old datum of reinserted orphan flows. - Patch2: memory leak of tracked deleted "pure" orphan rows. - Patch3: use after free of rows that became orphan after being deleted.
The 3 patches could probably be squashed into a single commit but to make review easier they're kept separate. Patches 1 and 3 don't add unit tests because I couldn't find a way to express the required order of operations in ovsdb-idl.at. The issue fixed by patch 2 is reproducible when runnning Ilya's OVS unit test for orphaned weak references with valgrind: https://patchwork.ozlabs.org/project/openvswitch/patch/[email protected]/ The issues fixed by patches 1 and 3 are reproducible when running OVN's "59: ovn -- 2 HVs, 2 LRs connected via LS, gateway router" unit test with Ilya's series to combine logical flows applied to OVN master: http://patchwork.ozlabs.org/project/ovn/list/?series=214426 Dumitru Ceara (3): ovsdb-idl: Fix memleak when reinserting tracked orphan rows. ovsdb-idl: Fix memleak when deleting orphan rows. ovsdb-idl: Fix use-after-free when deleting orphaned rows. lib/ovsdb-idl.c | 41 +++++++++++++++++++++++++++-------------- 1 file changed, 27 insertions(+), 14 deletions(-) _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
