This is a note to let you know that I've just added the patch titled net/qla3xxx: Fix a test in ql_reset_work() to the 5.17-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-qla3xxx-fix-a-test-in-ql_reset_work.patch and it can be found in the queue-5.17 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 39b6f8ba9533de8205e9a3f4151b0abafdca365b Author: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Sun May 15 20:07:02 2022 +0200 net/qla3xxx: Fix a test in ql_reset_work() [ Upstream commit 5361448e45fac6fb96738df748229432a62d78b6 ] test_bit() tests if one bit is set or not. Here the logic seems to check of bit QL_RESET_PER_SCSI (i.e. 4) OR bit QL_RESET_START (i.e. 3) is set. In fact, it checks if bit 7 (4 | 3 = 7) is set, that is to say QL_ADAPTER_UP. This looks harmless, because this bit is likely be set, and when the ql_reset_work() delayed work is scheduled in ql3xxx_isr() (the only place that schedule this work), QL_RESET_START or QL_RESET_PER_SCSI is set. This has been spotted by smatch.
