Here's his description: This series concludes the work I did for linux-5.5 on the compat_ioctl() cleanup, killing off fs/compat_ioctl.c and block/compat_ioctl.c by moving everything into drivers. Overall this would be a reduction both in complexity and line count, but as I'm also adding documentation the overall number of lines increases in the end. My plan was originally to keep the SCSI and block parts separate. This did not work easily because of interdependencies: I cannot do the final SCSI cleanup in a good way without first addressing the CDROM ioctls, so this is one series that I hope could be merged through either the block or the scsi git trees, or possibly both if you can pull in the same branch. The series comes in these steps: 1. clean up the sg v3 interface as suggested by Linus. I have talked about this with Doug Gilbert as well, and he would rebase his sg v4 patches on top of "compat: scsi: sg: fix v3 compat read/write interface" 2. Actually moving handlers out of block/compat_ioctl.c and block/scsi_ioctl.c into drivers, mixed in with cleanup patches 3. Document how to do this right. I keep getting asked about this, and it helps to point to some documentation file. The branch is based on another one that fixes a couple of bugs found during the creation of this series. Changes since v3: https://lore.kernel.org/lkml/20200102145552.1853992-1-arnd@arndb.de/ - Move sr_compat_ioctl fixup to correct patch (Ben Hutchings) - Add Reviewed-by tags Changes since v2: https://lore.kernel.org/lkml/20191217221708.3730997-1-arnd@arndb.de/ - Rebase to v5.5-rc4, which contains the earlier bugfixes - Fix sr_block_compat_ioctl() error handling bug found by Ben Hutchings - Fix idecd_locked_compat_ioctl() compat_ptr() bug - Don't try to handle HDIO_DRIVE_TASKFILE in drivers/ide - More documentation improvements Changes since v1: https://lore.kernel.org/lkml/20191211204306.1207817-1-arnd@arndb.de/ - move out the bugfixes into a branch for itself - clean up scsi sg driver further as suggested by Christoph Hellwig - avoid some ifdefs by moving compat_ptr() out of asm/compat.h - split out the blkdev_compat_ptr_ioctl function; bug spotted by Ben Hutchings - Improve formatting of documentation Signed-off-by: Martin K.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sector size of the block layer is 512 bytes, but integrity interval size might be different (in case of 4K block size of the media). At the initiator side the virtual start sector is the one that was originally submitted by the block layer (512 bytes) for the Reftag usage. The initiator converts the Reftag to integrity interval units and sends it to the target. So the target virtual start sector should be calculated at integrity interval units. prepare_fn() and complete_fn() don't remap correctly the Reftag when using incorrect units of the virtual start sector, which leads to the following protection error at the device: "blk_update_request: protection error, dev sdb, sector 2048 op 0x0:(READ) flags 0x10000 phys_seg 1 prio class 0" To fix that, set the seed in integrity interval units.

If this function is called to complete an expired (timed out) out command, the session command pointed by se_cmd is likely to be already deallocated by the target core at that moment. As the result, this access triggers a use-after-free warning from KASAN. This patch fixes the code not to touch se_cmd when completing timed out TCMU commands. It also resets the pointer to se_cmd at the time when the TCMU_CMD_BIT_EXPIRED flag is set because it is going to become invalid after calling target_complete_cmd() later in the same function, tcmu_check_expired_cmd().

Plus number of minor changes, spelling fixes and other trivia. The big merge conflict this time around is the SPDX licence tags. Following discussion on linux-next, we believe our version to be more accurate than the one in the tree, so the resolution is to take our version for all the SPDX conflicts" Note on the SPDX license tag conversion conflicts: the SCSI tree had done its own SPDX conversion, which in some cases conflicted with the treewide ones done by Thomas & co. In almost all cases, the conflicts were purely syntactic: the SCSI tree used the old-style SPDX tags ("GPL-2.0" and "GPL-2.0+") while the treewide conversion had used the new-style ones ("GPL-2.0-only" and "GPL-2.0-or-later"). In these cases I picked the new-style one. In a few cases, the SPDX conversion was actually different, though. As explained by James above, and in more detail in a pre-pull-request thread: "The other problem is actually substantive: In the libsas code Luben Tuikov originally specified gpl 2.0 only by dint of stating: * This file is licensed under GPLv2. In all the libsas files, but then muddied the water by quoting GPLv2 verbatim (which includes the or later than language). So for these files Christoph did the conversion to v2 only SPDX tags and Thomas converted to v2 or later tags" So in those cases, where the spdx tag substantially mattered, I took the SCSI tree conversion of it, but then also took the opportunity to turn the old-style "GPL-2.0" into a new-style "GPL-2.0-only" tag. Similarly, when there were whitespace differences or other differences to the comments around the copyright notices, I took the version from the SCSI tree as being the more specific conversion. Finally, in the spdx conversions that had no conflicts (because the treewide ones hadn't been done for those files), I just took the SCSI tree version as-is, even if it was old-style. The old-style conversions are perfectly valid, even if the "-only" and "-or-later" versions are perhaps more descriptive. * tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (185 commits) scsi: qla2xxx: move IO flush to the front of NVME rport unregistration scsi: qla2xxx: Fix NVME cmd and LS cmd timeout race condition scsi: qla2xxx: on session delete, return nvme cmd scsi: qla2xxx: Fix kernel crash after disconnecting NVMe devices scsi: megaraid_sas: Update driver version to 07.710.06.00-rc1 scsi: megaraid_sas: Introduce various Aero performance modes scsi: megaraid_sas: Use high IOPS queues based on IO workload scsi: megaraid_sas: Set affinity for high IOPS reply queues scsi: megaraid_sas: Enable coalescing for high IOPS queues scsi: megaraid_sas: Add support for High IOPS queues scsi: megaraid_sas: Add support for MPI toolbox commands scsi: megaraid_sas: Offload Aero RAID5/6 division calculations to driver scsi: megaraid_sas: RAID1 PCI bandwidth limit algorithm is applicable for only Ventura scsi: megaraid_sas: megaraid_sas: Add check for count returned by HOST_DEVICE_LIST DCMD scsi: megaraid_sas: Handle sequence JBOD map failure at driver level scsi: megaraid_sas: Don't send FPIO to RL Bypass queue scsi: megaraid_sas: In probe context, retry IOC INIT once if firmware is in fault scsi: megaraid_sas: Release Mutex lock before OCR in case of DCMD timeout scsi: megaraid_sas: Call disable_irq from process IRQ poll scsi: megaraid_sas: Remove few debug counters from IO path ...

The emulation code issues (M - 1) * N times more bios than requested, where M is the number of 512 blocks per real block size and N is the NUMBER OF LOGICAL BLOCKS specified in WRITE SAME command. So, for a device with 4k blocks, 7 * N more LBAs gets written after the requested range. The issue happens because the number of 512 byte sectors to be written is decreased one by one while the real bios are typically from 1 to 8 512 byte sectors per bio.
