The function hex2bin is used to load cryptographic keys into device
mapper targets dm-crypt and dm-integrity. It should take constant time
independent on the processed data, so that concurrently running
unprivileged code can't infer any information about the keys via
microarchitectural convert channels.
This patch changes the function hex_to_bin so that it contains no
branches and no memory accesses.
Note that this shouldn't cause performance degradation because the size
of the new function is the same as the size of the old function (on
x86-64) - and the new function causes no branch misprediction penalties.
I compile-tested this function with gcc on aarch64 alpha arm hppa hppa64
i386 ia64 m68k mips32 mips64 powerpc powerpc64 riscv sh4 s390x sparc32
sparc64 x86_64 and with clang on aarch64 arm hexagon i386 mips32 mips64
powerpc powerpc64 s390x sparc32 sparc64 x86_64 to verify that there are
no branches in the generated code.

Minh Yuan reported a concurrency use-after-free issue in the floppy code
between raw_cmd_ioctl and seek_interrupt.
[ It turns out this has been around, and that others have reported the
KASAN splats over the years, but Minh Yuan had a reproducer for it and
so gets primary credit for reporting it for this fix - Linus ]
The problem is, this driver tends to break very easily and nowadays,
nobody is expected to use FDRAWCMD anyway since it was used to
manipulate non-standard formats. The risk of breaking the driver is
higher than the risk presented by this race, and accessing the device
requires privileges anyway.
Let's just add a config option to completely disable this ioctl and
leave it disabled by default. Distros shouldn't use it, and only those
running on antique hardware might need to enable it.

It turns out that for the CONFIG_MMU=n builds, vmalloc_huge() was never
defined, since it's defined in mm/vmalloc.c, which doesn't get built for
the no-MMU configurations.
Just implement the trivial wrapper for the no-MMU case too. In fact,
just make it an alias to the existing __vmalloc() function that has the
same signature.

Since commit 559089e0a93d ("vmalloc: replace VM_NO_HUGE_VMAP with
VM_ALLOW_HUGE_VMAP"), the use of hugepage mappings for vmalloc is an
opt-in strategy, because it caused a number of problems that weren't
noticed until x86 enabled it too.
One of the issues was fixed by Nick Piggin in commit 3b8000ae185c
("mm/vmalloc: huge vmalloc backing pages should be split rather than
compound"), but I'm still worried about page protection issues, and
VM_FLUSH_RESET_PERMS in particular.
However, like the hash table allocation case (commit f2edd118d02d:
"page_alloc: use vmalloc_huge for large system hash"), the use of
kvmalloc() should be safe from any such games, since the returned
pointer might be a SLUB allocation, and as such no user should
reasonably be using it in any odd ways.
We also know that the allocations are fairly large, since it falls back
to the vmalloc case only when a kmalloc() fails. So using a hugepage
mapping seems both safe and relevant.
This patch does show a weakness in the opt-in strategy: since the opt-in
flag is in the 'vm_flags', not the usual gfp_t allocation flags, very
few of the usual interfaces actually expose it.
That's not much of an issue in this case that already used one of the
fairly specialized low-level vmalloc interfaces for the allocation, but
for a lot of other vmalloc() users that might want to opt in, it's going
to be very inconvenient.
We'll either have to fix any compatibility problems, or expose it in the
gfp flags (__GFP_COMP would have made a lot of sense) to allow normal
vmalloc() users to use hugepage mappings. That said, the cases that
really matter were probably already taken care of by the hash tabel
allocation.

Use vmalloc_huge() in alloc_large_system_hash() so that large system
hash (>= PMD_SIZE) could benefit from huge pages.

The current EOI handler for LEVEL triggered interrupts calls clk_enable(),
register IO, clk_disable(). The clock manipulation requires locking which
happens with IRQs disabled in clk_enable_lock(). Instead of turning the
clock on and off all the time, enable the clock in case LEVEL interrupt is
requested and keep the clock enabled until all LEVEL interrupts are freed.
The LEVEL interrupts are an exception on this platform and seldom used, so
this does not affect the common case.
This simplifies the LEVEL interrupt handling considerably and also fixes
the following splat found when using preempt-rt:

Test case 71 'Convert perf time to TSC' is not supported on s390.
Subtest 71.1 is skipped with the correct message, but subtest 71.2 is
not skipped and fails.
The root cause is function evlist__open() called from
test__perf_time_to_tsc(). evlist__open() returns -ENOENT because the
event cycles:u is not supported by the selected PMU, for example
platform s390 on z/VM or an x86_64 virtual machine.
The PMU driver returns -ENOENT in this case. This error is leads to the
failure.
Fix this by returning TEST_SKIP on -ENOENT.
Output before:
71: Convert perf time to TSC:
71.1: TSC support: Skip (This architecture does not support)
71.2: Perf time to TSC: FAILED!
Output after:
71: Convert perf time to TSC:
71.1: TSC support: Skip (This architecture does not support)
71.2: Perf time to TSC: Skip (perf_read_tsc_conversion is not supported)
This also happens on an x86_64 virtual machine:

Since commit bb30acae4c4dacfa ("perf report: Bail out --mem-mode if mem
info is not available") "perf mem report" and "perf report --mem-mode"
don't report result if the PERF_SAMPLE_DATA_SRC bit is missed in sample
type.
The commit ffab487052054162 ("perf: arm-spe: Fix perf report
--mem-mode") partially fixes the issue. It adds PERF_SAMPLE_DATA_SRC
bit for Arm SPE event, this allows the perf data file generated by
kernel v5.18-rc1 or later version can be reported properly.
On the other hand, perf tool still fails to be backward compatibility
for a data file recorded by an older version's perf which contains Arm
SPE trace data. This patch is a workaround in reporting phase, when
detects ARM SPE PMU event and without PERF_SAMPLE_DATA_SRC bit, it will
force to set the bit in the sample type and give a warning info.

If use command 'perf script -F,+data_src' to dump memory samples with
Arm SPE trace data, it reports error:
# perf script -F,+data_src
Samples for 'dummy:u' event do not have DATA_SRC attribute set. Cannot print 'data_src' field.
This is because the 'dummy:u' event is absent DATA_SRC bit in its sample
type, so if a file contains AUX area tracing data then always allow
field 'data_src' to be selected as an option for perf script.

Commit 5467801f1fcb ("gpio: Restrict usage of GPIO chip irq members
before initialization") attempted to fix a race condition that lead to a
NULL pointer, but in the process caused a regression for _AEI/_EVT
declared GPIOs.
This manifests in messages showing deferred probing while trying to
allocate IRQs like so:
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517
amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517
[ .. more of the same .. ]
The code for walking _AEI doesn't handle deferred probing and so this
leads to non-functional GPIO interrupts.
Fix this issue by moving the call to `acpi_gpiochip_request_interrupts`
to occur after gc->irc.initialized is set.

Pull mount_setattr fix from Christian Brauner:
"The recent cleanup in e257039f0fc7 ("mount_setattr(): clean the
control flow and calling conventions") switched the mount attribute
codepaths from do-while to for loops as they are more idiomatic when
walking mounts.
However, we did originally choose do-while constructs because if we
request a mount or mount tree to be made read-only we need to hold
writers in the following way: The mount attribute code will grab
lock_mount_hash() and then call mnt_hold_writers() which will
_unconditionally_ set MNT_WRITE_HOLD on the mount.
Any callers that need write access have to call mnt_want_write(). They
will immediately see that MNT_WRITE_HOLD is set on the mount and the
caller will then either spin (on non-preempt-rt) or wait on
lock_mount_hash() (on preempt-rt).
The fact that MNT_WRITE_HOLD is set unconditionally means that once
mnt_hold_writers() returns we need to _always_ pair it with
mnt_unhold_writers() in both the failure and success paths.
The do-while constructs did take care of this. But Al's change to a
for loop in the failure path stops on the first mount we failed to
change mount attributes _without_ going into the loop to call
mnt_unhold_writers().
This in turn means that once we failed to make a mount read-only via
mount_setattr() - i.e. there are already writers on that mount - we
will block any writers indefinitely. Fix this by ensuring that the for
loop always unsets MNT_WRITE_HOLD including the first mount we failed
to change to read-only. Also sprinkle a few comments into the cleanup
code to remind people about what is happening including myself. After
all, I didn't catch it during review.
This is only relevant on mainline and was reported by syzbot. Details
about the syzbot reports are all in the commit message"
