In our testing we've encountered use-after-free bugs, usually in the shape of double list_del, at a rate of 2-10 per week. Patches 2 and 3 fix two races that can both lead to use-after-free and after applying both of those patches, we have been bug-free for some weeks now.
Patch 1 is an unrelated trivial cleanup. I just happened to spot it while I was in the area. Joern Engel (3): target: removed unused transport_state flag target: close target_put_sess_cmd() vs. core_tmr_abort_task() race v5 target: simplify target_wait_for_sess_cmds() drivers/infiniband/ulp/srpt/ib_srpt.c | 2 +- drivers/scsi/qla2xxx/tcm_qla2xxx.c | 2 +- drivers/target/target_core_transport.c | 73 +++++++++----------------------- include/linux/kref.h | 33 +++++++++++++++ include/target/target_core_base.h | 3 -- include/target/target_core_fabric.h | 2 +- 6 files changed, 57 insertions(+), 58 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
