After commit 9a6d6a2d ("ata: make ata port as parent device of scsi host") manual driver unbind/remove causes use-after-free. Unbind unconditionally invokes devres_release_all() which calls ata_host_release() and frees ata_host/ata_port memory while it is still being referenced as a parent of SCSI host. When SCSI host is finally released scsi_host_dev_release() calls put_device(parent) and accesses freed ata_port memory. Add reference counting to make sure that ata_host lives long enough.

syzkaller hit a WARN() in ata_bmdma_qc_issue() when writing to /dev/sg0. This happened because it issued an ATA pass-through command (ATA_16) where the protocol field indicated that NCQ should be used -- but the device did not support NCQ. We could just remove the WARN() from libata-sff.c, but the real problem seems to be that the SCSI -> ATA translation code passes through NCQ commands without verifying that the device actually supports NCQ. Fix this by adding the appropriate check to ata_scsi_pass_thru(). Here's reproducer that works in QEMU when /dev/sg0 refers to a disk of the default type ("82371SB PIIX3 IDE"): #include <fcntl.h> #include <unistd.h> int main() { char buf[53] = { 0 }; buf[36] = 0x85; /* ATA_16 */ buf[37] = (12 << 1); /* FPDMA */ buf[38] = 0x1; /* Has data */ buf[51] = 0xC8; /* ATA_CMD_READ */ write(open("/dev/sg0", O_RDWR), buf, sizeof(buf)); } Fixes: ee7fb331 ("libata: add support for NCQ commands for SG interface") Reported-by: syzbot+2f69ca28df61bdfc77cd36af2e789850355a221e@syzkaller.appspotmail.com Cc: <stable@vger.kernel.org> # v4.4+ Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Tejun Heo <tj@kernel.org>

syzkaller hit a WARN() in ata_qc_issue() when writing to /dev/sg0. This happened because it issued a READ_6 command with no data buffer.

syzkaller reported a crash in ata_bmdma_fill_sg() when writing to /dev/sg1. The immediate cause was that the ATA command's scatterlist was not DMA-mapped, which causes 'pi - 1' to underflow, resulting in a write to 'qc->ap->bmdma_prd[0xffffffff]'. Strangely though, the flag ATA_QCFLAG_DMAMAP was set in qc->flags. The root cause is that when __ata_scsi_queuecmd() is preparing to relay a SCSI command to an ATAPI device, it doesn't correctly validate the CDB length before copying it into the 16-byte buffer 'cdb' in 'struct ata_queued_cmd'. Namely, it validates the fixed CDB length expected based on the SCSI opcode but not the actual CDB length, which can be larger due to the use of the SG_NEXT_CMD_LEN ioctl. Since 'flags' is the next member in ata_queued_cmd, a buffer overflow corrupts it. Fix it by requiring that the actual CDB length be <= 16 (ATAPI_CDB_LEN). [Really it seems the length should be required to be <= dev->cdb_len, but the current behavior seems to have been intentionally introduced by commit 607126c2 ("libata-scsi: be tolerant of 12-byte ATAPI commands in 16-byte CDBs") to work around a userspace bug in mplayer. Probably the workaround is no longer needed (mplayer was fixed in 2007), but continuing to allow lengths to up 16 appears harmless for now.] Here's a reproducer that works in QEMU when /dev/sg1 refers to the CD-ROM drive that qemu-system-x86_64 creates by default: #include <fcntl.h> #include <sys/ioctl.h> #include <unistd.h> #define SG_NEXT_CMD_LEN 0x2283 int main() { char buf[53] = { [36] = 0x7e, [52] = 0x02 }; int fd = open("/dev/sg1", O_RDWR); ioctl(fd, SG_NEXT_CMD_LEN, &(int){ 17 }); write(fd, buf, sizeof(buf)); } The crash was: BUG: unable to handle kernel paging request at ffff8cb97db37ffc IP: ata_bmdma_fill_sg drivers/ata/libata-sff.c:2623 [inline] IP: ata_bmdma_qc_prep+0xa4/0xc0 drivers/ata/libata-sff.c:2727 PGD fb6c067 P4D fb6c067 PUD 0 Oops: 0002 [#1] SMP CPU: 1 PID: 150 Comm: syz_ata_bmdma_q Not tainted 4.15.0-next-20180202 #99 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.11.0-20171110_100015-anatol 04/01/2014 [...] Call Trace: ata_qc_issue+0x100/0x1d0 drivers/ata/libata-core.c:5421 ata_scsi_translate+0xc9/0x1a0 drivers/ata/libata-scsi.c:2024 __ata_scsi_queuecmd drivers/ata/libata-scsi.c:4326 [inline] ata_scsi_queuecmd+0x8c/0x210 drivers/ata/libata-scsi.c:4375 scsi_dispatch_cmd+0xa2/0xe0 drivers/scsi/scsi_lib.c:1727 scsi_request_fn+0x24c/0x530 drivers/scsi/scsi_lib.c:1865 __blk_run_queue_uncond block/blk-core.c:412 [inline] __blk_run_queue+0x3a/0x60 block/blk-core.c:432 blk_execute_rq_nowait+0x93/0xc0 block/blk-exec.c:78 sg_common_write.isra.7+0x272/0x5a0 drivers/scsi/sg.c:806 sg_write+0x1ef/0x340 drivers/scsi/sg.c:677 __vfs_write+0x31/0x160 fs/read_write.c:480 vfs_write+0xa7/0x160 fs/read_write.c:544 SYSC_write fs/read_write.c:589 [inline] SyS_write+0x4d/0xc0 fs/read_write.c:581 do_syscall_64+0x5e/0x110 arch/x86/entry/common.c:287 entry_SYSCALL_64_after_hwframe+0x21/0x86 Fixes: 607126c2 ("libata-scsi: be tolerant of 12-byte ATAPI commands in 16-byte CDBs") Reported-by: syzbot+1ff6f9fcc3c35f1c72a95e26528c8e7e3276e4da@syzkaller.appspotmail.com Cc: <stable@vger.kernel.org> # v2.6.24+ Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Tejun Heo <tj@kernel.org>

except, again, POLLFREE and POLL_BUSY_LOOP. With this, we finally get to the promised end result: - POLL{IN,OUT,...} are plain integers and *not* in __poll_t, so any stray instances of ->poll() still using those will be caught by sparse. - eventpoll.c and select.c warning-free wrt __poll_t - no more kernel-side definitions of POLL... - userland ones are visible through the entire kernel (and used pretty much only for mangle/demangle) - same behavior as after the first series (i.e. sparc et.al. epoll(2) working correctly).

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

59f47eff ("powerpc/pci: Use of_irq_parse_and_map_pci() helper") replaced of_irq_parse_pci() + irq_create_of_mapping() with of_irq_parse_and_map_pci(), but neglected to capture the virq returned by irq_create_of_mapping(), so virq remained zero, which caused INTx configuration to fail. Save the virq value returned by of_irq_parse_and_map_pci() and correct the virq declaration to match the of_irq_parse_and_map_pci() signature.
