block: memory allocations in bounce_clone_bio must not fail
The caller can't cope with a failure from bounce_clone_bio, so use __GFP_NOFAIL for the passthrough case. bio_alloc_bioset already won't fail due to the use of mempools. And yes, we need to get rid of this bock layer bouncing code entirely sooner or later.. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk> |

block: fix bounce_clone_bio for passthrough bios
Now that bio_alloc_bioset does not fall back to kmalloc for a NULL

conventions.

block-crypto-fallback: use a bio_set for splitting bios
bio_split with a NULL bs argumen used to fall back to kmalloc the
bio, which does not guarantee forward progress and could to deadlocks.
Now that the overloading of the NULL bs argument to bio_alloc_bioset
has been removed it crashes instead. Fix all that by using a special
crafted bioset.

blk-settings: align max_sectors on "logical_block_size" boundary
We get I/O errors when we run md-raid1 on the top of dm-integrity on the top of ramdisk. device-mapper: integrity: Bio not aligned on 8 sectors: 0xff00, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0xff00, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0xffff, 0x1 device-mapper: integrity: Bio not aligned on 8 sectors: 0xffff, 0x1 device-mapper: integrity: Bio not aligned on 8 sectors: 0x8048, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0x8147, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0x8246, 0xff device-mapper: integrity: Bio not aligned on 8 sectors: 0x8345, 0xbb The ramdisk device has logical_block_size 512 and max_sectors 255. The dm-integrity device uses logical_block_size 4096 and it doesn't affect the "max_sectors" value - thus, it inherits 255 from the ramdisk. So, we have a device with max_sectors not aligned on logical_block_size. The md-raid device sees that the underlying leg has max_sectors 255 and it will split the bios on 255-sector boundary, making the bios unaligned on logical_block_size. In order to fix the bug, we round down max_sectors to logical_block_size.

block: reopen the device in blkdev_reread_part
Historically the BLKRRPART ioctls called into the now defunct ->revalidate
method, which caused the sd driver to check if any media is present.
When the ->revalidate method was removed this revalidation was lost,
leading to lots of I/O errors when using the eject command. Fix this by
reopening the device to rescan the partitions, and thus calling the
revalidation logic in the sd driver.

blktrace: remove debugfs file dentries from struct blk_trace
These debugfs dentries do not need to be saved for anything as the whole directory and everything in it is properly cleaned up when the parent directory is removed. So remove them from struct blk_trace and don't save them when created as it's not necessary.

nbd: handle device refs for DESTROY_ON_DISCONNECT properly
There exists a race where we can be attempting to create a new nbd
configuration while a previous configuration is going down, both
configured with DESTROY_ON_DISCONNECT. Normally devices all have a
reference of 1, as they won't be cleaned up until the module is torn
down. However with DESTROY_ON_DISCONNECT we'll make sure that there is
only 1 reference (generally) on the device for the config itself, and
then once the config is dropped, the device is torn down.
The race that exists looks like this
TASK1 TASK2
nbd_genl_connect()
idr_find()
refcount_inc_not_zero(nbd)
* count is 2 here ^^
nbd_config_put()
nbd_put(nbd) (count is 1)
setup new config
check DESTROY_ON_DISCONNECT
put_dev = true
if (put_dev) nbd_put(nbd)
* free'd here ^^
In nbd_genl_connect() we assume that the nbd ref count will be 2,
however clearly that won't be true if the nbd device had been setup as
DESTROY_ON_DISCONNECT with its prior configuration. Fix this by getting
rid of the runtime flag to check if we need to mess with the nbd device
refcount, and use the device NBD_DESTROY_ON_DISCONNECT flag to check if
we need to adjust the ref counts. This was reported by syzkaller with
the following kasan dump

kyber: introduce kyber_depth_updated()
Hang occurs when user changes the scheduler queue depth, by writing to the 'nr_requests' sysfs file of that device. The details of the environment that we found the problem are as follows: an eMMC block device total driver tags: 16 default queue_depth: 32 kqd->async_depth initialized in kyber_init_sched() with queue_depth=32 Then we change queue_depth to 256, by writing to the 'nr_requests' sysfs file. But kqd->async_depth don't be updated after queue_depth changes. Now the value of async depth is too small for queue_depth=256, this may cause hang. This patch introduces kyber_depth_updated(), so that kyber can update async depth when queue depth changes.

loop: fix I/O error on fsync() in detached loop devices
There's an I/O error on fsync() in a detached loop device
if it has been previously attached.
The issue is write cache is enabled in the attach path in
loop_configure() but it isn't disabled in the detach path;
thus it remains enabled in the block device regardless of
whether it is attached or not.
Now fsync() can get an I/O request that will just be failed
later in loop_queue_rq() as device's state is not 'Lo_bound'.
So, disable write cache in the detach path.
Do so based on the queue flag, not the loop device flag for
read-only (used to enable) as the queue flag can be changed
via sysfs even on read-only loop devices (e.g., losetup -r.)
Test-case:
# DEV=/dev/loop7
# IMG=/tmp/image
# truncate --size 1M $IMG
# losetup $DEV $IMG
# losetup -d $DEV
Before:
# strace -e fsync parted -s $DEV print 2>&1 | grep fsync
fsync(3) = -1 EIO (Input/output error)
Warning: Error fsyncing/closing /dev/loop7: Input/output error

block: fix potential IO hang when turning off io_poll
QUEUE_FLAG_POLL flag will be cleared when turning off 'io_poll', while at that moment there may be IOs stuck in hw queue uncompleted. The following polling routine won't help reap these IOs, since blk_poll() will return immediately because of cleared QUEUE_FLAG_POLL flag. Thus these IOs will hang until they finnaly time out. The hang out can be observed by 'fio --engine=io_uring iodepth=1', while turning off 'io_poll' at the same time. To fix this, freeze and flush the request queue first when turning off 'io_poll'.

Pull selinux updates from Paul Moore:
"We've got a good handful of patches for SELinux this time around; with
everything passing the selinux-testsuite and applying cleanly to your
tree as of a few minutes ago. The highlights are:
- Add support for labeling anonymous inodes, and extend this new
support to userfaultfd.
- Fallback to SELinux genfs file labeling if the filesystem does not
have xattr support. This is useful for virtiofs which can vary in
its xattr support depending on the backing filesystem.
- Classify and handle MPTCP the same as TCP in SELinux.
- Ensure consistent behavior between inode_getxattr and
inode_listsecurity when the SELinux policy is not loaded. This
fixes a known problem with overlayfs.
- A couple of patches to prune some unused variables from the SELinux
code, mark private variables as static, and mark other variables as
__ro_after_init or __read_mostly"

sound updates for 5.12
A relatively calm release at this time, and no massive code changes
are found in the stats, while a wide range of code refactoring and
cleanup have been done.
Note that this update includes the tree-wide trivial changes for
dropping the return value from ISA remove callbacks, too.
Below lists up some highlight:
* ALSA Core:
- Support for the software jack injection via debugfs
- Fixes for sync_stop PCM operations
* HD-audio and USB-audio:
- A few usual HD-audio device quirks
- Updates for Tegra HD-audio
- More quirks for Pioneer and other USB-audio devices
- Stricter state checks at USB-audio disconnection
* ASoC:
- Continued code refactoring, cleanup and fixes in ASoC core API
- A KUnit testsuite for the topology code
- Lots of ASoC Intel driver Realtek codec updates, quirk additions and
fixes
- Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
- Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers
* Others:
- Drop return value from ISA driver remove callback
- Cleanup with DIV_ROUND_UP() macro
- FireWire updates, HDSP output loopback support

Merge tag 'sound-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"A relatively calm release at this time, and no massive code changes
are found in the stats, while a wide range of code refactoring and
cleanup have been done.
Note that this update includes the tree-wide trivial changes for
dropping the return value from ISA remove callbacks, too.
Below lists up some highlight:
ALSA Core:
- Support for the software jack injection via debugfs
- Fixes for sync_stop PCM operations
HD-audio and USB-audio:
- A few usual HD-audio device quirks
- Updates for Tegra HD-audio
- More quirks for Pioneer and other USB-audio devices
- Stricter state checks at USB-audio disconnection
ASoC:
- Continued code refactoring, cleanup and fixes in ASoC core API
- A KUnit testsuite for the topology code
- Lots of ASoC Intel driver Realtek codec updates, quirk additions
and fixes
- Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
- Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers
Others:
- Drop return value from ISA driver remove callback
- Cleanup with DIV_ROUND_UP() macro
- FireWire updates, HDSP output loopback support"

x86:
- Support for userspace to emulate Xen hypercalls
- Raise the maximum number of user memslots
- Scalability improvements for the new MMU. Instead of the complex
"fast page fault" logic that is used in mmu.c, tdp_mmu.c uses an
rwlock so that page faults are concurrent, but the code that can run
against page faults is limited. Right now only page faults take the
lock for reading; in the future this will be extended to some
cases of page table destruction. I hope to switch the default MMU
around 5.12-rc3 (some testing was delayed due to Chinese New Year).
- Cleanups for MAXPHYADDR checks
- Use static calls for vendor-specific callbacks
- On AMD, use VMLOAD/VMSAVE to save and restore host state
- Stop using deprecated jump label APIs
- Workaround for AMD erratum that made nested virtualization unreliable
- Support for LBR emulation in the guest
- Support for communicating bus lock vmexits to userspace
- Add support for SEV attestation command
- Miscellaneous cleanups
PPC:
- Support for second data watchpoint on POWER10
- Remove some complex workarounds for buggy early versions of POWER9
- Guest entry/exit fixes
ARM64
- Make the nVHE EL2 object relocatable
- Cleanups for concurrent translation faults hitting the same page
- Support for the standard TRNG hypervisor call
- A bunch of small PMU/Debug fixes
- Simplification of the early init hypercall handling
Non-KVM changes (with acks):
- Detection of contended rwlocks (implemented only for qrwlocks,
because KVM only needs it for x86)
- Allow __DISABLE_EXPORTS from assembly code
- Provide a saner follow_pfn replacements for modules

The performance event updates for v5.12 are:
- Add CPU-PMU support for Intel Sapphire Rapids CPUs
- Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter
sampling event feedback. Not used yet, but is intended for Golden Cove
CPU-PMU, which can provide both the instruction latency and the cache
latency information for memory profiling events.
- Remove experimental, default-disabled perfmon-v4 counter_freezing support
that could only be enabled via a boot option. The hardware is hopelessly
broken, we'd like to make sure nobody starts relying on this, as it would
only end in tears.
- Fix energy/power events on Intel SPR platforms
- Simplify the uprobes resume_execution() logic
- Misc smaller fixes.

Scheduler updates for v5.12:
[ NOTE: unfortunately this tree had to be freshly rebased today,
it's a same-content tree of 82891be90f3c (-next published)
merged with v5.11.
The main reason for the rebase was an authorship misattribution
problem with a new commit, which we noticed in the last minute,
and which we didn't want to be merged upstream. The offending
commit was deep in the tree, and dependent commits had to be
rebased as well. ]
- Core scheduler updates:
- Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the
preempt=none/voluntary/full boot options (default: full),
to allow distros to build a PREEMPT kernel but fall back to
close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling
behavior via a boot time selection.
There's also the /debug/sched_debug switch to do this runtime.
This feature is implemented via runtime patching (a new variant of static calls).
The scope of the runtime patching can be best reviewed by looking
at the sched_dynamic_update() function in kernel/sched/core.c.
( Note that the dynamic none/voluntary mode isn't 100% identical,
for example preempt-RCU is available in all cases, plus the
preempt count is maintained in all models, which has runtime
overhead even with the code patching. )
The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast majority
of distributions, are supposed to be unaffected.
- Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that
was found via rcutorture triggering a hang. The bug is that
rcu_idle_enter() may wake up a NOCB kthread, but this happens after
the last generic need_resched() check. Some cpuidle drivers fix it
by chance but many others don't.
In true 2020 fashion the original bug fix has grown into a 5-patch
scheduler/RCU fix series plus another 16 RCU patches to address
the underlying issue of missed preemption events. These are the
initial fixes that should fix current incarnations of the bug.
- Clean up rbtree usage in the scheduler, by providing & using the following
consistent set of rbtree APIs:
partial-order; less() based:
- rb_add(): add a new entry to the rbtree
- rb_add_cached(): like rb_add(), but for a rb_root_cached
total-order; cmp() based:
- rb_find(): find an entry in an rbtree
- rb_find_add(): find an entry, and add if not found
- rb_find_first(): find the first (leftmost) matching entry
- rb_next_match(): continue from rb_find_first()
- rb_for_each(): iterate a sub-tree using the previous two
- Improve the SMP/NUMA load-balancer: scan for an idle sibling in a single pass.
This is a 4-commit series where each commit improves one aspect of the idle
sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU utilization
metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by reducing the number
of active LB attempts & lengthen the load-balancing interval. This improves
stress-ng mmapfork performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can result in
too high utilization values
- Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()
- Clean up task priority related defines, remove *USER_*PRIO and
USER_PRIO()
- Simplify the sched_init_numa() deduplication sort
- Documentation updates
- Fix EAS bug in update_misfit_status(), which degraded the quality
of energy-balancing
- Smaller cleanups

rcu_idle_enter() may wake up a NOCB kthread, but this happens after
the last generic need_resched() check. Some cpuidle drivers fix it
by chance but many others don't.
In true 2020 fashion the original bug fix has grown into a 5-patch
scheduler/RCU fix series plus another 16 RCU patches to address the
underlying issue of missed preemption events. These are the initial
fixes that should fix current incarnations of the bug.
- Clean up rbtree usage in the scheduler, by providing & using the
following consistent set of rbtree APIs:
partial-order; less() based:
- rb_add(): add a new entry to the rbtree
- rb_add_cached(): like rb_add(), but for a rb_root_cached
total-order; cmp() based:
- rb_find(): find an entry in an rbtree
- rb_find_add(): find an entry, and add if not found
- rb_find_first(): find the first (leftmost) matching entry
- rb_next_match(): continue from rb_find_first()
- rb_for_each(): iterate a sub-tree using the previous two
- Improve the SMP/NUMA load-balancer: scan for an idle sibling in a
single pass. This is a 4-commit series where each commit improves
one aspect of the idle sibling scan logic.
- Improve the cpufreq cooling driver by getting the effective CPU
utilization metrics from the scheduler
- Improve the fair scheduler's active load-balancing logic by
reducing the number of active LB attempts & lengthen the
load-balancing interval. This improves stress-ng mmapfork
performance.
- Fix CFS's estimated utilization (util_est) calculation bug that can
result in too high utilization values
Misc updates & fixes:
- Fix the HRTICK reprogramming & optimization feature
- Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code
- Reduce dl_add_task_root_domain() overhead
- Fix uprobes refcount bug
- Process pending softirqs in flush_smp_call_function_from_idle()
- Clean up task priority related defines, remove *USER_*PRIO and
USER_PRIO()
- Simplify the sched_init_numa() deduplication sort
- Documentation updates
- Fix EAS bug in update_misfit_status(), which degraded the quality
of energy-balancing
- Smaller cleanups"

Pull io_uring updates from Jens Axboe:
"Highlights from this cycles are things like request recycling and
task_work optimizations, which net us anywhere from 10-20% of speedups
on workloads that mostly are inline.
This work was originally done to put io_uring under memcg, which adds
considerable overhead. But it's a really nice win as well. Also worth
highlighting is the LOOKUP_CACHED work in the VFS, and using it in
io_uring. Greatly speeds up the fast path for file opens.
Summary:
- Put io_uring under memcg protection. We accounted just the rings
themselves under rlimit memlock before, now we account everything.
- Request cache recycling, persistent across invocations (Pavel, me)
- First part of a cleanup/improvement to buffer registration (Bijan)
- SQPOLL fixes (Hao)
- File registration NULL pointer fixup (Dan)
- LOOKUP_CACHED support for io_uring
- Disable /proc/thread-self/ for io_uring, like we do for /proc/self
- Add Pavel to the io_uring MAINTAINERS entry
- Tons of code cleanups and optimizations (Pavel)
- Support for skip entries in file registration (Noah)"
