block: brd: associate with queue until adding disk
brd_free() may be called in failure path on one brd instance which disk isn't added yet, so release handler of gendisk may free the associated request_queue early and causes the following use-after-free[1]. This patch fixes this issue by associating gendisk with request_queue just before adding disk.

block: fix the DISCARD request merge
There are two cases when handle DISCARD merge. If max_discard_segments == 1, the bios/requests need to be contiguous to merge. If max_discard_segments > 1, it takes every bio as a range and different range needn't to be contiguous. But now, attempt_merge screws this up. It always consider contiguity for DISCARD for the case max_discard_segments > 1 and cannot merge contiguous DISCARD for the case max_discard_segments == 1, because rq_attempt_discard_merge always returns false in this case. This patch fixes both of the two cases above.

block: Introduce blk_revalidate_disk_zones()
Drivers exposing zoned block devices have to initialize and maintain correctness (i.e. revalidate) of the device zone bitmaps attached to the device request queue (seq_zones_bitmap and seq_zones_wlock). To simplify coding this, introduce a generic helper function blk_revalidate_disk_zones() suitable for most (and likely all) cases. This new function always update the seq_zones_bitmap and seq_zones_wlock bitmaps as well as the queue nr_zones field when called for a disk using a request based queue. For a disk using a BIO based queue, only the number of zones is updated since these queues do not have schedulers and so do not need the zone bitmaps. With this change, the zone bitmap initialization code in sd_zbc.c can be replaced with a call to this function in sd_zbc_read_zones(), which is called from the disk revalidate block operation method. A call to blk_revalidate_disk_zones() is also added to the null_blk driver for devices created with the zoned mode enabled. Finally, to ensure that zoned devices created with dm-linear or dm-flakey expose the correct number of zones through sysfs, a call to blk_revalidate_disk_zones() is added to dm_table_set_restrictions(). The zone bitmaps allocated and initialized with blk_revalidate_disk_zones() are freed automatically from __blk_release_queue() using the block internal function blk_queue_free_zone_bitmaps().

block: add a report_zones method
Dispatching a report zones command through the request queue is a major pain due to the command reply payload rewriting necessary. Given that blkdev_report_zones() is executing everything synchronously, implement report zones as a block device file operation instead, allowing major simplification of the code in many places. sd, null-blk, dm-linear and dm-flakey being the only block device drivers supporting exposing zoned block devices, these drivers are modified to provide the device side implementation of the report_zones() block device file operation. For device mappers, a new report_zones() target type operation is defined so that the upper block layer calls blkdev_report_zones() can be propagated down to the underlying devices of the dm targets. Implementation for this new operation is added to the dm-linear and dm-flakey targets.

block: Expose queue nr_zones in sysfs
Expose through sysfs the nr_zones field of struct request_queue. Exposing this value helps in debugging disk issues as well as facilitating scripts based use of the disk (e.g. blktests). For zoned block devices, the nr_zones field indicates the total number of zones of the device calculated using the known disk capacity and zone size. This number of zones is always 0 for regular block devices. Since nr_zones is defined conditionally with CONFIG_BLK_DEV_ZONED, introduce the blk_queue_nr_zones() function to return the correct value for any device, regardless if CONFIG_BLK_DEV_ZONED is set.

block: Improve zone reset execution
There is no need to synchronously execute all REQ_OP_ZONE_RESET BIOs necessary to reset a range of zones. Similarly to what is done for discard BIOs in blk-lib.c, all zone reset BIOs can be chained and executed asynchronously and a synchronous call done only for the last BIO of the chain. Modify blkdev_reset_zones() to operate similarly to blkdev_issue_discard() using the next_bio() helper for chaining BIOs. To avoid code duplication of that function in blk_zoned.c, rename next_bio() into blk_next_bio() and declare it as a block internal function in blk.h.

scsi: sd_zbc: Fix sd_zbc_check_zones() error checks
The unsigned 32 bits overflow check for the zone size value is already
done within sd_zbc_check_zones() with the test:
} else if (logical_to_sectors(sdkp->device, zone_blocks) > UINT_MAX) {
so there is no need to check again for an out of range value in
sd_zbc_read_zones(). Simplify the code and fix sd_zbc_check_zones()
error return to -EFBIG instead of -ENODEV if the zone size is too large.
Change the return type of sd_zbc_check_zones() to an int for the error
code and return the zone size (zone_blocks) through a u32 pointer to
avoid overflowing the signed 32 return value.

scsi: sd_zbc: Reduce boot device scan and revalidate time
Handling checks of ZBC device capacity using the max_lba field of the REPORT ZONES command reply for disks with rc_basis == 0 can be done using the same report zones command reply used to check the "same" field. Avoid executing a report zones command solely to check the disk capacity by merging sd_zbc_check_capacity() into sd_zbc_check_zone_size() and renaming that function to sd_zbc_check_zones(). This removes a costly execution of a full report zones command and so reduces device scan duration at boot time as well as the duration of disk revalidate calls. Furthermore, setting the partial report bit in the REPORT ZONES command cdb can significantly reduce this command execution time as the device does not have to count and report the total number of zones that could be reported assuming a large enough reply buffer. A non-partial zone report is necessary only for the first execution of report zones used to check the same field value (to ensure that this value applies to all zones of the disk). All other calls to sd_zbc_report_zones() can use a partial report to reduce execution time. Using a 14 TB ZBC disk, these simple changes reduce device scan time at boot from about 3.5s down to about 900ms. Disk revalidate times are also reduced from about 450ms down to 230ms.

xen/blkfront: avoid NULL blkfront_info dereference on device removal
If a block device is hot-added when we are out of grants,
gnttab_grant_foreign_access fails with -ENOSPC (log message "28
granting access to ring page") in this code path:
talk_to_blkback ->
setup_blkring ->
xenbus_grant_ring ->
gnttab_grant_foreign_access
and the failing path in talk_to_blkback sets the driver_data to NULL:
destroy_blkring:
blkif_free(info, 0);
mutex_lock(&blkfront_mutex);
free_info(info);
mutex_unlock(&blkfront_mutex);
dev_set_drvdata(&dev->dev, NULL);
This results in a NULL pointer BUG when blkfront_remove and blkif_free
try to access the failing device's NULL struct blkfront_info.

sound updates for 4.20
There have been little changes in ALSA core stuff, but ASoC core still
kept rolling for the continued restructuring. The rest are lots of
small driver-specific changes and some minor API updates.
Here are highlights:
General:
- Appropriate fall-through annotations everywhere
- Some code cleanup in memalloc code, handling non-cacahed pages more
commonly in the helper
- Deployment of SNDRV_PCM_INFO_SYNC_APPLPTR flag consistently
Drivers:
- More HD-audio CA0132 codec improvement for supporting other Creative
boards
- Plumbing legacy HD-audio codecs as ASoC BE on Intel SST; this will
give move support of existing HD-audio devices with DSP
- A few device-specific HD-audio quirks as usual
- New quirk for RME CC devices and correction for B&W PX for USB-audio
- FireWire: code refactoring including devres usages
ASoC Core:
- Continued componentization works; it's almost done!
- A bunch of new for_each_foo macros
- Cleanups and fixes in DAPM code
ASoC Drivers:
- MCLK support for several different devices, including CS42L51, STM32
SAI, and MAX98373
- Support for Allwinner A64 CODEC analog, Intel boards with DA7219 and
MAX98927, Meson AXG PDM inputs, Nuvoton NAU8822, Renesas R8A7744 and
TI PCM3060

f2fs-for-4.20-rc1
In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata. Enhancement: - add checksum to keep superblock contents more safe - add checkpoint=disable/enable to support A/B update of entire filesystem - use plug for readahead IO in readdir - add more IO counts to avoid block layer hacks Bug fix: - prevent data corruption issue for hardware encryption - fix IO hang issues when GC is heavily triggered - add missing up_read in __write_node_page - recover inode metadata during roll-forward recovery flow - fix null pointer dereference issue in wrongly configured discard map There are some more sanity checks and minor bug fixes as well. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlvPzt4ACgkQQBSofoJI UNJLfg/8Ch9TWfbeUEH+6ioJ4pdURHmb/gFOQRSGX8Nu+HkuPJQD8pqlheK7n5g7 Pw3K6NLXHmL2d8xSNFbBwYmUSAeoXTc0J4nqX0sUJ6m7SKsuQ45Qe3A90faKEoAA ce7flWKVI+aJcGurBe99GOM69ptfyjb1w/8UGB0pcXUDq4oaRv5a1UtAAm92WF7H 4/7jYD3ub5aeSynwe16wWR4B5aXJT0l0FcZYicI6IRY1mOjMtXuQt72AY+ffSzBt yQ6qb8OEl3xpfQZHHH00ZfvarkTBzXJGZwquiPX/CPzVcee8cOqPp+XZqN7CXBEr 9ItezxYiUxOkKCl12Al8DynHZa6o2kEnWxgd49WkL/cNdInnvf5MD0kdfCV3KfQa CAR0UVe2yTg5mGLemtTSWveLdHfI7+LhDmURuXmoTUa9GWldw0413qqVVypcsizv QOAS86hSicrVK+bDnCA70i8Xxw7YEnAyrfCcgihU84NZSi7nTPUYj4xtMd9SzRnK JO8gA79D7lcWaxUS4r9I+JBDwWcfMQZRPS7PFbvoGWilIwsEaocCPYNgtjCTsAsK 1fePqiF/265Q4lapmEhEjhuQSNH2xfJQZ4ux1OU+eS3OTDjbEAFBeVPZImh7Mo7F dkpXQwfcqAXPzOM4QAJ6hFX40D8SWMAlId6XGiIfJlrFmEUAxBk= =VDw4 -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've added 1) superblock checksum feature, 2) implemented new mount option which we can disable/enable checkpoint to provide atomic updates of entire filesystem, 3) refactored quota operations to enhance its consistency along with checkpoint, 4) fixed subtle IO hang conditions and roll-forward recovery flow to resurrect any fsync'ed inode metadata.

Merge tag 'xfs-4.20-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pul xfs updates from Dave Chinner:
"There's not a huge amount of change in this cycle - Darrick has been
out of action for a couple of months (hence me sending the last few
pull requests), so we decided a quiet cycle mainly focussed on bug
fixes was a good idea. Darrick will take the helm again at the end of
this merge window.
FYI, I may be sending another update later in the cycle - there's a
pending rework of the clone/dedupe_file_range code that fixes numerous
bugs that is spread amongst the VFS, XFS and ocfs2 code. It has been
reviewed and tested, Al and I just need to work out the details of the
merge, so it may come from him rather than me.
Summary:
- only support filesystems with unwritten extents
- add definition for statfs XFS magic number
- remove unused parameters around reflink code
- more debug for dangling delalloc extents
- cancel COW extents on extent swap targets
- fix quota stats output and clean up the code
- refactor some of the attribute code in preparation for parent
pointers
- fix several buffer handling bugs"

Pull btrfs updates from David Sterba:
"This is the first batch with fixes and some nice performance
improvements.
Preliminary results show eg. more files/sec in fsmark, better perf on
multi-threaded workloads (filebench, dbench), fewer context switches
and overall better memory allocation characteristics (multiple
benchmarks).
Apart from general performance, there's an improvement for qgroups +
balance workload that's been troubling our users.
Note for stable: there are 20+ patches tagged for stable, out of 90.
Not all of them apply cleanly on all stable versions but the conflicts
are mostly due to simple cleanups and resolving should be obvious. The
fixes are otherwise independent.
Performance improvements:
- transition between blocking and spinning modes of path is gone,
which originally resulted to more unnecessary wakeups and updates
to the path locks, the effects are measurable and improve latency
and scalability
- qgroups: first batch of changes that should speedup balancing with
qgroups on, skip quota accounting on unchanged subtrees, overall
gain is about 30+% in runtime
- use rb-tree with cached first node for several structures, small
improvement to avoid pointer chasing
Fixes:
- trim
- fix: some blockgroups could have been missed if their logical
address was past the total filesystem size (ie. after a lot of
balancing)
- better error reporting, after processing blockgroups and whole
device
- fix: continue trimming block groups after an error is
encountered
- check for trim support of the device earlier and avoid some
unnecessary work
- less interaction with transaction commit that improves latency
on slower storage (eg. image files over NFS)
- fsync
- fix warning when replaying log after fsync of a O_TMPFILE
- fix wrong dentries after fsync of file that got its parent
replaced
- qgroups: fix rescan that might misc some dirty groups
- don't clean dirty pages during buffered writes, this could lead to
lost updates in some corner cases
- some block groups could have been delayed in creation, if the
allocation triggered another one
- error handling improvements
Cleanups:
- removed unused struct members and variables
- function return type cleanups
- delayed refs code refactoring
- protect against deadlock that could be caused by crafted image that
tries to allocate from a tree that's locked already"

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo updates from Eric Biederman: "I have been slowly sorting out siginfo and this is the culmination of that work. The primary result is in several ways the signal infrastructure has been made less error prone. The code has been updated so that manually specifying SEND_SIG_FORCED is never necessary. The conversion to the new siginfo sending functions is now complete, which makes it difficult to send a signal without filling in the proper siginfo fields. At the tail end of the patchset comes the optimization of decreasing the size of struct siginfo in the kernel from 128 bytes to about 48 bytes on 64bit. The fundamental observation that enables this is by definition none of the known ways to use struct siginfo uses the extra bytes. This comes at the cost of a small user space observable difference. For the rare case of siginfo being injected into the kernel only what can be copied into kernel_siginfo is delivered to the destination, the rest of the bytes are set to 0. For cases where the signal and the si_code are known this is safe, because we know those bytes are not used. For cases where the signal and si_code combination is unknown the bits that won't fit into struct kernel_siginfo are tested to verify they are zero, and the send fails if they are not. I made an extensive search through userspace code and I could not find anything that would break because of the above change. If it turns out I did break something it will take just the revert of a single change to restore kernel_siginfo to the same size as userspace siginfo. Testing did reveal dependencies on preferring the signo passed to sigqueueinfo over si->signo, so bit the bullet and added the complexity necessary to handle that case. Testing also revealed bad things can happen if a negative signal number is passed into the system calls. Something no sane application will do but something a malicious program or a fuzzer might do. So I have fixed the code that performs the bounds checks to ensure negative signal numbers are handled" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (80 commits) signal: Guard against negative signal numbers in copy_siginfo_from_user32 signal: Guard against negative signal numbers in copy_siginfo_from_user signal: In sigqueueinfo prefer sig not si_signo signal: Use a smaller struct siginfo in the kernel signal: Distinguish between kernel_siginfo and siginfo signal: Introduce copy_siginfo_from_user and use it's return value signal: Remove the need for __ARCH_SI_PREABLE_SIZE and SI_PAD_SIZE signal: Fail sigqueueinfo if si_signo != sig signal/sparc: Move EMT_TAGOVF into the generic siginfo.h signal/unicore32: Use force_sig_fault where appropriate signal/unicore32: Generate siginfo in ucs32_notify_die signal/unicore32: Use send_sig_fault where appropriate signal/arc: Use force_sig_fault where appropriate signal/arc: Push siginfo generation into unhandled_exception signal/ia64: Use force_sig_fault where appropriate signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn signal/ia64: Use the generic force_sigsegv in setup_frame signal/arm/kvm: Use send_sig_mceerr signal/arm: Use send_sig_fault where appropriate signal/arm: Use force_sig_fault where appropriate ... |
