The IDE driver creates some passthru requests which never get submitted to the block layer in such a way that blk_account_io_start() gets called. However, the driver still calls __blk_mq_end_request() in ide_end_rq() which will call blk_account_io_completion() which tries to dereferences req->part which is never set. See ide_prep_sense() for an example of where these requests come from. To fix this, blk_account_io_completion() and blk_account_io_done() should do nothing if req->part is not set. The back trace of this bug is: BUG: kernel NULL pointer dereference, address: 000002ac #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page *pde = 00000000 Oops: 0002 [#1] CPU: 0 PID: 237 Comm: kworker/0:1H Not tainted 5.4.0-rc2-00011-g48d9b0d4 #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1 04/01/2014 Workqueue: kblockd drive_rq_insert_work EIP: blk_account_io_completion+0x7a/0xf0 Code: 89 54 24 08 31 d2 89 4c 24 04 31 c9 c7 04 24 02 00 00 00 c1 ee 09 e8 f5 21 a6 ff e8 70 5c a7 ff 8b 53 60 8d 04 bd 00 00 00 00 <01> b4 02 ac 02 00 00 8b 9a 88 02 00 00 85 db 74 11 85 d2 74 51 8b EAX: 00000000 EBX: f5b80000 ECX: 00000000 EDX: 00000000 ESI: 00000000 EDI: 00000000 EBP: f3031e70 ESP: f3031e54 DS: 007b ES: 007b FS: 0000 GS: 0000 SS: 0068 EFLAGS: 00010046 CR0: 80050033 CR2: 000002ac CR3: 03c25000 CR4: 000406d0 Call Trace: <IRQ> blk_update_request+0x85/0x420 ide_end_rq+0x38/0xa0 ide_complete_rq+0x3d/0x70 cdrom_newpc_intr+0x258/0xba0 ide_intr+0x135/0x250 __handle_irq_event_percpu+0x3e/0x250 handle_irq_event_percpu+0x1f/0x50 handle_irq_event+0x32/0x60 handle_level_irq+0x6c/0x110 handle_irq+0x72/0xa0 </IRQ> do_IRQ+0x45/0xad common_interrupt+0x115/0x11c Fixes: 48d9b0d4 ("block: account statistics for passthrough requests") Reported-by:

Pull AFS fixes from David Howells: "Fixes for AFS plus one patch to make debugging easier: - Fix how addresses are matched to server records. This is currently incorrect which means cache invalidation callbacks from the server don't necessarily get delivered correctly. This causes stale data and metadata to be seen under some circumstances. - Make the dynamic root superblock R/W so that rpm/dnf can reapply the SELinux label to it when upgrading the Fedora filesystem-afs package. If the filesystem is R/O, this fails and the upgrade fails. It might be better in future to allow setxattr from an LSM to bypass the R/O protections, if only for pseudo-filesystems. - Fix the parsing of mountpoint strings. The mountpoint object has to have a terminal dot, whereas the source/device string passed to mount should not. This confuses type-forcing suffix detection leading to the wrong volume variant being mounted. - Make lookups in the dynamic root superblock for creation events (such as mkdir) fail with EOPNOTSUPP rather than something like EEXIST. The dynamic root only allows implicit creation by the ->lookup() method - and only if the target cell exists. - Fix the looking up of an AFS superblock to include the cell in the matching key - otherwise all volumes with the same ID number are treated as the same thing, irrespective of which cell they're in. - Show the volume name of each volume in the volume records displayed in /proc/net/afs/<cell>/volumes. This proved useful in debugging as it provides a way to map the volume IDs to names, where the names are what appear in /proc/mounts" * tag 'afs-fixes-20191211' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: afs: Show volume name in /proc/net/afs/<cell>/volumes afs: Fix missing cell comparison in afs_test_super() afs: Fix creation calls in the dynamic root to fail with EOPNOTSUPP afs: Fix mountpoint parsing afs: Fix SELinux setting security label on /afs afs: Fix afs_find_server lookups for ipv4 peers

If we submit an unknown opcode and have fd == -1, io_op_needs_file() will return true as we default to needing a file. Then when we go and assign the file, we find the 'fd' invalid and return -EBADF. We really should be returning -EINVAL for that case, as we normally do for unsupported opcodes. Change io_op_needs_file() to have the following return values: 0 - does not need a file 1 - does need a file < 0 - error value and use this to pass back the right value for this invalid case.

There's no need to separately check for signals while inside the locked region, since we're going to do "wait_event_interruptible()" right afterwards anyway, and the error handling is much simpler there. The check for whether we had already read anything was also redundant, since we no longer do the odd merging of reads when there are pending writers. But perhaps more importantly, this adds commentary about why we still need to wake up possible writers even though we didn't read any data, and why we can skip all the finishing touches now if we get a signal (or had a signal pending) while waiting for more data. [ This is a split-out cleanup from my "make pipe IO use exclusive wait queues" thing, which I can't apply because it triggers a nasty bug in the GNU make jobserver - Linus ] Signed-off-by:

Fix missing cell comparison in afs_test_super(). Without this, any pair volumes that have the same volume ID will share a superblock, no matter the cell, unless they're in different network namespaces. Normally, most users will only deal with a single cell and so they won't see this. Even if they do look into a second cell, they won't see a problem unless they happen to hit a volume with the same ID as one they've already got mounted.

Fix the lookup method on the dynamic root directory such that creation calls, such as mkdir, open(O_CREAT), symlink, etc. fail with EOPNOTSUPP rather than failing with some odd error (such as EEXIST). lookup() itself tries to create automount directories when it is invoked. These are cached locally in RAM and not committed to storage. Signed-off-by:

Each AFS mountpoint has strings that define the target to be mounted. This is required to end in a dot that is supposed to be stripped off. The string can include suffixes of ".readonly" or ".backup" - which are supposed to come before the terminal dot. To add to the confusion, the "fs lsmount" afs utility does not show the terminal dot when displaying the string. The kernel mount source string parser, however, assumes that the terminal dot marks the suffix and that the suffix is always "" and is thus ignored. In most cases, there is no suffix and this is not a problem - but if there is a suffix, it is lost and this affects the ability to mount the correct volume. The command line mount command, on the other hand, is expected not to include a terminal dot - so the problem doesn't arise there. Fix this by making sure that the dot exists and then stripping it when passing the string to the mount configuration.
