blk-mq: fix start_time_ns and alloc_time_ns for pre-allocated rq
The iocost rely on rq start_time_ns and alloc_time_ns to tell saturation
state of the block device. Most of the time request is allocated after
rq_qos_throttle() and its alloc_time_ns or start_time_ns won't be affected.

nvme: don't reject probe due to duplicate IDs for single-ported PCIe devices
While duplicate IDs are still very harmful, including the potential to easily
see changing devices in /dev/disk/by-id, it turn out they are extremely
common for cheap end user NVMe devices.
Relax our check for them for so that it doesn't reject the probe on
single-ported PCIe devices, but prints a big warning instead. In doubt
we'd still like to see quirk entries to disable the potential for
changing supposed stable device identifier links, but this will at least
allow users how have two (or more) of these devices to use them without
having to manually add a new PCI ID entry with the quirk through sysfs or
by patching the kernel.

block/mq-deadline: Fix a bug in deadline_from_pos()
A bug was introduced in deadline_from_pos() while implementing the
suggestion to use round_down() in the following code:
pos -= bdev_offset_from_zone_start(rq->q->disk->part0, pos);
This patch makes deadline_from_pos() use round_down() such that 'pos' is
rounded down.

nvme: ensure disabling pairs with unquiesce
If any error handling that disables the controller fails to queue the reset work, like if the state changed to disconnected inbetween, then the failed teardown needs to unquiesce the queues since it's no longer paired with reset_work. Just make sure that the controller can be put into a resetting state prior to starting the disable so that no other handling can change the queue states while recovery is happening.

blk-crypto: use dynamic lock class for blk_crypto_profile::lock
When a device-mapper device is passing through the inline encryption
support of an underlying device, calls to blk_crypto_evict_key() take
the blk_crypto_profile::lock of the device-mapper device, then take the
blk_crypto_profile::lock of the underlying device (nested). This isn't
a real deadlock, but it causes a lockdep report because there is only
one lock class for all instances of this lock.
Lockdep subclasses don't really work here because the hierarchy of block
devices is dynamic and could have more than 2 levels.
Instead, register a dynamic lock class for each blk_crypto_profile, and
associate that with the lock.
This avoids false-positive lockdep reports like the following:
============================================
WARNING: possible recursive locking detected

fscryptctl/1421 is trying to acquire lock:

but task is already holding lock:

afs: Fix accidental truncation when storing data
When an AFS FS.StoreData RPC call is made, amongst other things it is
given the resultant file size to be. On the server, this is processed
by truncating the file to new size and then writing the data.
Now, kafs has a lock (vnode->io_lock) that serves to serialise
operations against a specific vnode (ie. inode), but the parameters for
the op are set before the lock is taken. This allows two writebacks
(say sync and kswapd) to race - and if writes are ongoing the writeback
for a later write could occur before the writeback for an earlier one if
the latter gets interrupted.
Note that afs_writepages() cannot take i_mutex and only takes a shared
lock on vnode->validate_lock.
Also note that the server does the truncation and the write inside a
lock, so there's no problem at that end.
Fix this by moving the calculation for the proposed new i_size inside
the vnode->io_lock. Also reset the iterator (which we might have read
from) and update the mtime setting there.

firewire updates for 6.5-rc1
The updates consist of three parts; UAPI update, OHCI driver update, and several bug fixes. Firstly, the 1394 OHCI specification defines method to retrieve hardware time stamps for asynchronous communication, which was previously unavailable in user space. This change adds new events to the UAPI, allowing applications to retrieve the time when asynchronous packet are received and sent. The new events are tested in the breeding edge of libhinawa and look to work well. The new version of libhinawa will be released after current merge window is closed. * https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/ Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI hardware, This change modernizes the driver by managed resource (devres) framework.

module: fix init_module_from_file() error handling
Vegard Nossum pointed out two different problems with the error handling
in init_module_from_file():
(a) the idempotent loading code didn't clean up properly in some error
cases, leaving the on-stack 'struct idempotent' element still in
the hash table
(b) failure to read the module file would nonsensically update the
'invalid_kread_bytes' stat counter with the error value
The first error is quite nasty, in that it can then cause subsequent
idempotent loads of that same file to access stale stack contents of the
previous failure. The case may not happen in any normal situation
(explaining all the "Tested-by's on the original change), and requires
admin privileges, but syzkaller triggers random bad behavior as a
result:
BUG: soft lockup in sys_finit_module
BUG: unable to handle kernel paging request in init_module_from_file
general protection fault in init_module_from_file
INFO: task hung in init_module_from_file
KASAN: out-of-bounds Read in init_module_from_file
KASAN: slab-out-of-bounds Read in init_module_from_file
...
The second error is fairly benign and just leads to nonsensical stats
(and has been around since the debug stats were added).
Vegard also provided a patch for the idempotent loading issue, but I'd
rather re-organize the code and make it more legible using another level
of helper functions than add the usual "goto out" error handling.

rdma: fix INFINIBAND_USER_ACCESS dependency
After a change to the bnxt_re driver, it fails to link when
CONFIG_INFINIBAND_USER_ACCESS is disabled:
aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o: in function `bnxt_re_handler_BNXT_RE_METHOD_ALLOC_PAGE':
ib_verbs.c:(.text+0xd64): undefined reference to `ib_uverbs_get_ucontext_file'
aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x168): undefined reference to `uverbs_idr_class'
aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x1a8): undefined reference to `uverbs_destroy_def_handler'
The problem is that the 'bnxt_re_uapi_defs' structure is built
unconditionally and references a couple of functions that are never
really called in this configuration but instead require other functions
that are left out.
Adding an #ifdef around the new code, or a Kconfig dependency would
address this problem, but adding the compile-time check inside of the
UAPI_DEF_CHAIN_OBJ_TREE_NAMED() macro seems best because that also
addresses the problem in other drivers that may run into the same
dependency.

ARM64:
* Eager page splitting optimization for dirty logging, optionally
allowing for a VM to avoid the cost of hugepage splitting in the stage-2
fault path.
* Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with
services that live in the Secure world. pKVM intervenes on FF-A calls
to guarantee the host doesn't misuse memory donated to the hyp or a
pKVM guest.
* Support for running the split hypervisor with VHE enabled, known as
'hVHE' mode. This is extremely useful for testing the split
hypervisor on VHE-only systems, and paves the way for new use cases
that depend on having two TTBRs available at EL2.
* Generalized framework for configurable ID registers from userspace.
KVM/arm64 currently prevents arbitrary CPU feature set configuration
from userspace, but the intent is to relax this limitation and allow
userspace to select a feature set consistent with the CPU.
* Enable the use of Branch Target Identification (FEAT_BTI) in the
hypervisor.
* Use a separate set of pointer authentication keys for the hypervisor
when running in protected mode, as the host is untrusted at runtime.
* Ensure timer IRQs are consistently released in the init failure
paths.
* Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps
(FEAT_EVT), as it is a register commonly read from userspace.
* Erratum workaround for the upcoming AmpereOne part, which has broken
hardware A/D state management.
RISC-V:
* Redirect AMO load/store misaligned traps to KVM guest
* Trap-n-emulate AIA in-kernel irqchip for KVM guest
* Svnapot support for KVM Guest
s390:
* New uvdevice secret API
* CMM selftest and fixes
* fix racy access to target CPU for diag 9c
x86:
* Fix missing/incorrect #GP checks on ENCLS
* Use standard mmu_notifier hooks for handling APIC access page
* Drop now unnecessary TR/TSS load after VM-Exit on AMD
* Print more descriptive information about the status of SEV and SEV-ES during
module load
* Add a test for splitting and reconstituting hugepages during and after
dirty logging
* Add support for CPU pinning in demand paging test
* Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes
included along the way
* Add a "nx_huge_pages=never" option to effectively avoid creating NX hugepage
recovery threads (because nx_huge_pages=off can be toggled at runtime)
* Move handling of PAT out of MTRR code and dedup SVM+VMX code
* Fix output of PIC poll command emulation when there's an interrupt
* Add a maintainer's handbook to document KVM x86 processes, preferred coding
style, testing expectations, etc.
* Misc cleanups, fixes and comments

* Miscellaneous bugfixes and cleanups

kgdb patches for 6.5
Fairly small changes this cycle.
* An additional static inline function when kgdb is not enabled to
reduce boilerplate in arch files.
* kdb will now handle input with linefeeds more like carriage return.
This will make little difference for interactive use but can make
it script to use expect-like interaction with kdb.
* A couple of warning fixes.

gfs2: Add quota_change type
Function do_qc has two main uses: (1) to re-sync the local quota changes (qd) to the master quotas, and (2) normal quota changes. In the case of normal quota changes, the change can be positive or negative, as the quota usage goes up and down. Before this patch function do_qc was distinguishing one from another by whether the resulting value is or isn't zero: In the case of a re-sync (called do_sync) the quota value is moved from the temporary value to a master value, so the amount is added to one and subtracted from the other. The problem is that since the values can be positive or negative we can occasionally run into situations where we are not doing a re-sync but the quota change just happens to cancel out the previous value. In the case of a re-sync extra references and locks are taken, and so do_qc needs to release them. In the case of a normal quota change, no extra references and locks are taken, so it must not try to release them. The problem is: if the quota change is not a re-sync but the value just happens to cancel out the original quota change, the resulting zero value fools do_qc into thinking this is a re-sync and therefore it must release the extra references. This results in problems, mainly having to do with slot reference numbers going smaller than zero. This patch introduces new constants, QC_SYNC and QC_CHANGE so do_qc can really tell the difference. For QC_SYNC calls it must release the extra references acquired by gfs2_quota_unlock's call to qd_check_sync. For QC_CHANGE calls it does not have extra references to put. Note that this allows quota changes back to a value of zero, and so I removed an assert warning related to that.

gfs2: Use memcpy_{from,to}_page where appropriate
Replace kmap_local_page() + memcpy() + kunmap_local() sequences with
memcpy_{from,to}_page() where we are not doing anything else with the
mapped page.

gfs2: Convert remaining kmap_atomic calls to kmap_local_page
Replace the remaining instances of kmap_atomic() ... kunmap_atomic() with kmap_local_page() ... kunmap_local(). In gfs2_write_buf_to_page(), we can call flush_dcache_page() after unmapping the page. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> |

gfs2: Replace deprecated kmap_atomic with kmap_local_page
kmap_atomic() is deprecated in favor of kmap_local_{folio,page}().
Therefore, replace kmap_atomic() with kmap_local_page() in
gfs2_internal_read() and stuffed_readpage().
kmap_atomic() disables page-faults and preemption (the latter only for
!PREEMPT_RT kernels), However, the code within the mapping/un-mapping in
gfs2_internal_read() and stuffed_readpage() does not depend on the
above-mentioned side effects.
Therefore, a mere replacement of the old API with the new one is all that
is required (i.e., there is no need to explicitly add any calls to
pagefault_disable() and/or preempt_disable()).

gfs2: Replace sd_freeze_state with SDF_FROZEN flag
Replace sd_freeze_state with a new SDF_FROZEN flag. There no longer is a need for indicating that a freeze is in progress (SDF_STARTING_FREEZE); we are now protecting the critical sections with the sd_freeze_mutex. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> |

gfs2: Rework freeze / thaw logic
So far, at mount time, gfs2 would take the freeze glock in shared mode and then immediately drop it again, turning it into a cached glock that can be reclaimed at any time. To freeze the filesystem cluster-wide, the node initiating the freeze would take the freeze glock in exclusive mode, which would cause the freeze glock's freeze_go_sync() callback to run on each node. There, gfs2 would freeze the filesystem and schedule gfs2_freeze_func() to run. gfs2_freeze_func() would re-acquire the freeze glock in shared mode, thaw the filesystem, and drop the freeze glock again. The initiating node would keep the freeze glock held in exclusive mode. To thaw the filesystem, the initiating node would drop the freeze glock again, which would allow gfs2_freeze_func() to resume on all nodes, leaving the filesystem in the thawed state. It turns out that in freeze_go_sync(), we cannot reliably and safely freeze the filesystem. This is primarily because the final unmount of a filesystem takes a write lock on the s_umount rw semaphore before calling into gfs2_put_super(), and freeze_go_sync() needs to call freeze_super() which also takes a write lock on the same semaphore, causing a deadlock. We could work around this by trying to take an active reference on the super block first, which would prevent unmount from running at the same time. But that can fail, and freeze_go_sync() isn't actually allowed to fail. To get around this, this patch changes the freeze glock locking scheme as follows: At mount time, each node takes the freeze glock in shared mode. To freeze a filesystem, the initiating node first freezes the filesystem locally and then drops and re-acquires the freeze glock in exclusive mode. All other nodes notice that there is contention on the freeze glock in their go_callback callbacks, and they schedule gfs2_freeze_func() to run. There, they freeze the filesystem locally and drop and re-acquire the freeze glock before re-thawing the filesystem. This is happening outside of the glock state engine, so there, we are allowed to fail. From a cluster point of view, taking and immediately dropping a glock is indistinguishable from taking the glock and only dropping it upon contention, so this new scheme is compatible with the old one. Thanks to Li Dong <lidong@vivo.com> for reporting a locking bug in gfs2_freeze_func() in a previous version of this commit. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> |
