2020-10-27scsi: qla2xxx: remove incorrect sparse #ifdefLinus Torvalds1-4/+0
The code to try to shut up sparse warnings about questionable locking didn't shut up sparse: it made the result not parse as valid C at all, since the end result now has a label with no statement. The proper fix is to just always lock the hardware, the same way Bart did in commit 8ae178760b23 ("scsi: qla2xxx: Simplify the functions for dumping firmware"). That avoids the whole problem with having locking that is not statically obvious. But in the meantime, just remove the incorrect attempt at trying to avoid a sparse warning that just made things worse. This was exposed by commit 3e6efab865ac ("scsi: qla2xxx: Fix reset of MPI firmware"), very similarly to how commit cbb01c2f2f63 ("scsi: qla2xxx: Fix MPI failure AEN (8200) handling") exposed the same problem in another place, and caused that commit 8ae178760b23. Please don't add code to just shut up sparse without actually fixing what sparse complains about.

2020-09-30scsi: qla2xxx: Fix reset of MPI firmwareArun Easi1-36/+13
Normally, the MPI firmware is reset when an MPI dump is collected. If an unsaved MPI dump exists in the driver, though, an alternate mechanism is used. This mechanism, which was not fully correct, is not recommended and instead an MPI dump template walk is suggested to perform the MPI reset. To allow for the MPI dump template walk, extra space is reserved in the MPI dump buffer which gets used only when there is already an MPI dump in place.

2020-04-24scsi: qla2xxx: Fix MPI failure AEN (8200) handlingArun Easi1-22/+99
Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular firmware dump is also taken and then chip reset. This is disruptive to IOs and not required. Make the firmware dump collection, followed by chip reset, optional (not done by default). Firmware dump buffer and MPI dump buffer are independent of each other with this change and each can have dump that was taken at two different times for two different issues. The MPI dump is saved in a separate buffer and is retrieved differently from firmware dump. To collect full dump on MPI failure AEN, a module parameter is introduced: ql2xfulldump_on_mpifail (default: 0) Link: https://lore.kernel.org/r/20200331104015.24868-2-njavali@marvell.com Reported-by: kbuild test robot <lkp@intel.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Signed-off-by: Arun Easi <aeasi@marvell.com> Signed-off-by: Nilesh Javali <njavali@marvell.com> Signed-off-by: Martin K.

[ Upstream Commit 84e32a06f4f8756ce9ec3c8dc7e97896575f0771 ] Commit 84e32a0 ("qla2xxx: Use pci_enable_msix_range() instead of pci_enable_msix()") introduced a regression when target mode is enabled. In qla24xx_enable_msix(), ha->max_rsp_queues was incorrectly set to a value higher than the number of response queues allocated causing an invalid dereference. Specifically here in qla2x00_init_rings(): *rsp->in_ptr = 0; Add additional check to make sure the pointer is valid. following call stack will be seen ---- 8< ---- RIP: 0010:[<ffffffffa02ccadc>] [<ffffffffa02ccadc>] qla2x00_init_rings+0xdc/0x320 [qla2xxx] RSP: 0018:ffff880429447dd8 EFLAGS: 00010082 ....
