Driver core fixes for 5.15-rc4
Here are some driver core and kernfs fixes for reported issues for
5.15-rc4. These fixes include:
- kernfs positive dentry bugfix
- debugfs_create_file_size error path fix
- cpumask sysfs file bugfix to preserve the user/kernel abi (has
been reported multiple times.)
- devlink fixes for mdiobus devices as reported by the subsystem
maintainers.
Also included in here are some devlink debugging changes to make it
easier for people to report problems when asked. They have already
helped with the mdiobus and other subsystems reporting issues.
All of these have been linux-next for a while with no reported issues.

cachefiles: Fix oops in trace_cachefiles_mark_buried due to NULL object
In cachefiles_mark_object_buried, the dentry in question may not have an owner, and thus our cachefiles_object pointer may be NULL when calling the tracepoint, in which case we will also not have a valid debug_id to print in the tracepoint. Check for NULL object in the tracepoint and if so, just set debug_id to MAX_UINT as was done in |

perf/core: fix userpage->time_enabled of inactive events
Users of rdpmc rely on the mmapped user page to calculate accurate
time_enabled. Currently, userpage->time_enabled is only updated when the
event is added to the pmu. As a result, inactive event (due to counter
multiplexing) does not have accurate userpage->time_enabled. This can
be reproduced with something like:
/* open 20 task perf_event "cycles", to create multiplexing */
fd = perf_event_open(); /* open task perf_event "cycles" */
userpage = mmap(fd); /* use mmap and rdmpc */
while (true) {
time_enabled_mmap = xxx; /* use logic in perf_event_mmap_page */
time_enabled_read = read(fd).time_enabled;
if (time_enabled_mmap > time_enabled_read)
BUG();
}
Fix this by updating userpage for inactive events in merge_sched_in.

af_unix: fix races in sk_peer_pid and sk_peer_cred accesses
Jann Horn reported that SO_PEERCRED and SO_PEERGROUPS implementations are racy, as af_unix can concurrently change sk_peer_pid and sk_peer_cred. In order to fix this issue, this patch adds a new spinlock that needs to be used whenever these fields are read or written. Jann also pointed out that l2cap_sock_get_peer_pid_cb() is currently reading sk->sk_peer_pid which makes no sense, as this field is only possibly set by AF_UNIX sockets. We will have to clean this in a separate patch. This could be done by reverting |

sound fixes for 5.15-rc4
It became a slightly large collection of changes, partly because
I've been off in the last weeks. Most of changes are small and
scattered while a bit big change is found in HD-audio Realtek
codec driver; it's a very device-specific fix that has been long
wanted, so I decided to pick up although it's in the middle RC.
Some highlights:
* A new guard ioctl for ALSA rawmidi API to avoid the misuse of
the new timestamp framing mode; it's for a regression fix
* HD-audio: a revert of the 5.15 change that might work badly,
new quirks for Lenovo Legion & co, a follow-up fix for CS8409
* ASoC: lots of SOF-related fixes, fsl component fixes, corrections of
mediatek drivers
* USB-audio: fix for the PM resume
* FireWire: oxfw and motu fixes

A set of fixes for X86:
- Prevent sending the wrong signal when protection keys are enabled and
the kernel handles a fault in the vsyscall emulation.
- Invoke early_reserve_memory() before invoking e820_memory_setup() which
is required to make the Xen dom0 e820 hooks work correctly.
- Use the correct data type for the SETZ operand in the EMQCMDS
instruction wrapper.
- Prevent undefined behaviour to the potential unaligned accesss in the
instroction decoder library.

A fix for a bug with restartable sequences and KVM. KVM's handling
of TIF_NOTIFY_RESUME, e.g. for task migration, clears the flag without
informing rseq and leads to stale data in userspace's rseq struct.
I'm sending this as a separate pull request since it's not code
that I usually touch. In particular, patch 2 ("entry: rseq: Call
rseq_handle_notify_resume() in tracehook_notify_resume()") is just a
cleanup to try and make future bugs less likely. If you prefer this to
be sent via Thomas and only in 5.16, please speak up.

driver core: fw_devlink: Add support for FWNODE_FLAG_NEEDS_CHILD_BOUND_ON_ADD
If a parent device is also a supplier to a child device, fw_devlink=on by
design delays the probe() of the child device until the probe() of the
parent finishes successfully.
However, some drivers of such parent devices (where parent is also a
supplier) expect the child device to finish probing successfully as soon as
they are added using device_add() and before the probe() of the parent
device has completed successfully. One example of such a case is discussed
in the link mentioned below.
Add a flag to make fw_devlink=on not enforce these supplier-consumer
relationships, so these drivers can continue working.

ALSA: rawmidi: introduce SNDRV_RAWMIDI_IOCTL_USER_PVERSION
The new framing mode causes the user space regression, because
the alsa-lib code does not initialize the reserved space in
the params structure when the device is opened.

KVM: x86: Query vcpu->vcpu_idx directly and drop its accessor
Read vcpu->vcpu_idx directly instead of bouncing through the one-line wrapper, kvm_vcpu_get_idx(), and drop the wrapper. The wrapper is a remnant of the original implementation and serves no purpose; remove it before it gains more users. Back when kvm_vcpu_get_idx() was added by commit |

entry: rseq: Call rseq_handle_notify_resume() in tracehook_notify_resume()
Invoke rseq_handle_notify_resume() from tracehook_notify_resume() now
that the two function are always called back-to-back by architectures
that have rseq. The rseq helper is stubbed out for architectures that
don't support rseq, i.e. this is a nop across the board.
Note, tracehook_notify_resume() is horribly named and arguably does not
belong in tracehook.h as literally every line of code in it has nothing
to do with tracing. But, that's been true since commit

cpumask: Omit terminating null byte in cpumap_print_{list,bitmask}_to_buf
The changes in the patch series [1] introduced a terminating null byte
when reading from cpulist or cpumap sysfs files, for example:
$ xxd /sys/devices/system/node/node0/cpulist
00000000: 302d 310a 00 0-1..
Before this change, the output looked as follows:
$ xxd /sys/devices/system/node/node0/cpulist
00000000: 302d 310a 0-1.
Fix this regression by excluding the terminating null byte from the
returned length in cpumap_print_list_to_buf and
cpumap_print_bitmask_to_buf.

Pull AFS fixes from David Howells:
"Fixes for AFS problems that can cause data corruption due to
interaction with another client modifying data cached locally:
- When d_revalidating a dentry, don't look at the inode to which it
points. Only check the directory to which the dentry belongs. This
was confusing things and causing the silly-rename cleanup code to
remove the file now at the dentry of a file that got deleted.
- Fix mmap data coherency. When a callback break is received that
relates to a file that we have cached, the data content may have
been changed (there are other reasons, such as the user's rights
having been changed). However, we're checking it lazily, only on
entry to the kernel, which doesn't happen if we have a writeable
shared mapped page on that file.
We make the kernel keep track of mmapped files and clear all PTEs
mapping to that file as soon as the callback comes in by calling
unmap_mapping_pages() (we don't necessarily want to zap the
pagecache). This causes the kernel to be reentered when userspace
tries to access the mmapped address range again - and at that point
we can query the server and, if we need to, zap the page cache.
Ideally, I would check each file at the point of notification, but
that involves poking the server[*] - which is holding an exclusive
lock on the vnode it is changing, waiting for all the clients it
notified to reply. This could then deadlock against the server.
Further, invalidating the pagecache might call ->launder_page(),
which would try to write to the file, which would definitely
deadlock. (AFS doesn't lease file access).
[*] Checking to see if the file content has changed is a matter of
comparing the current data version number, but we have to ask
the server for that. We also need to get a new callback promise
and we need to poke the server for that too.
- Add some more points at which the inode is validated, since we're
doing it lazily, notably in ->read_iter() and ->page_mkwrite(), but
also when performing some directory operations.
Ideally, checking in ->read_iter() would be done in some derivation
of filemap_read(). If we're going to call the server to read the
file, then we get the file status fetch as part of that.
- The above is now causing us to make a lot more calls to
afs_validate() to check the inode - and afs_validate() takes the
RCU read lock each time to make a quick check (ie.
afs_check_validity()). This is entirely for the purpose of checking
cb_s_break to see if the server we're using reinitialised its list
of callbacks - however this isn't a very common event, so most of
the time we're taking this needlessly.
Add a new cell-wide counter to count the number of
reinitialisations done by any server and check that - and only if
that changes, take the RCU read lock and check the server list (the
server list may change, but the cell a file is part of won't).
- Don't update vnode->cb_s_break and ->cb_v_break inside the validity
checking loop. The cb_lock is done with read_seqretry, so we might
go round the loop a second time after resetting those values - and
that could cause someone else checking validity to miss something
(I think).
Also included are patches for fixes for some bugs encountered whilst
debugging this:
- Fix a leak of afs_read objects and fix a leak of keys hidden by
that.
- Fix a leak of pages that couldn't be added to extend a writeback.
- Fix the maintenance of i_blocks when i_size is changed by a local
write or a local dir edit"

x86/fault: Fix wrong signal when vsyscall fails with pkey
The function __bad_area_nosemaphore() calls kernelmode_fixup_or_oops()
with the parameter @signal being actually @pkey, which will send a
signal numbered with the argument in @pkey.
This bug can be triggered when the kernel fails to access user-given
memory pages that are protected by a pkey, so it can go down the
do_user_addr_fault() path and pass the !user_mode() check in
__bad_area_nosemaphore().
Most cases will simply run the kernel fixup code to make an -EFAULT. But
when another condition current->thread.sig_on_uaccess_err is met, which
is only used to emulate vsyscall, the kernel will generate the wrong
signal.
Add a new parameter @pkey to kernelmode_fixup_or_oops() to fix this.

swiotlb-xen: this is PV-only on x86
The code is unreachable for HVM or PVH, and it also makes little sense
in auto-translated environments. On Arm, with
xen_{create,destroy}_contiguous_region() both being stubs, I have a hard
time seeing what good the Xen specific variant does - the generic one
ought to be fine for all purposes there. Still Arm code explicitly
references symbols here, so the code will continue to be included there.
Instead of making PCI_XEN's "select" conditional, simply drop it -
SWIOTLB_XEN will be available unconditionally in the PV case anyway, and
is - as explained above - dead code in non-PV environments.
This in turn allows dropping the stubs for
xen_{create,destroy}_contiguous_region(), the former of which was broken
anyway - it failed to set the DMA handle output.

KVM: arm64: Fix PMU probe ordering
Russell reported that since 5.13, KVM's probing of the PMU has
started to fail on his HW. As it turns out, there is an implicit
ordering dependency between the architectural PMU probing code and
and KVM's own probing. If, due to probe ordering reasons, KVM probes
before the PMU driver, it will fail to detect the PMU and prevent it
from being advertised to guests as well as the VMM.
Obviously, this is one probing too many, and we should be able to
deal with any ordering.
Add a callback from the PMU code into KVM to advertise the registration
of a host CPU PMU, allowing for any probing order.

A set of x86 fixes:
- Prevent a infinite loop in the MCE recovery on return to user space,
which was caused by a second MCE queueing work for the same page and
thereby creating a circular work list.
- Make kern_addr_valid() handle existing PMD entries, which are marked not
present in the higher level page table, correctly instead of blindly
dereferencing them.
- Pass a valid address to sanitize_phys(). This was caused by the mixture
of inclusive and exclusive ranges. memtype_reserve() expect 'end' being
exclusive, but sanitize_phys() wants it inclusive. This worked so far,
but with end being the end of the physical address space the fail is
exposed.
- Increase the maximum supported GPIO numbers for 64bit. Newer SoCs exceed
the previous maximum.

parisc: Declare pci_iounmap() parisc version only when CONFIG_PCI enabled
Linus noticed odd declaration rules for pci_iounmap() in iomap.h and
pci_iomap.h, where it dependend on either NO_GENERIC_PCI_IOPORT_MAP or
GENERIC_IOMAP when CONFIG_PCI was disabled.
Testing on parisc seems to indicate that we need pci_iounmap() only when
CONFIG_PCI is enabled, so the declaration of pci_iounmap() can be moved
cleanly into pci_iomap.h in sync with the declarations of pci_iomap().
