The current sanity check for nilfs2 geometry information lacks checks for
the number of segments stored in superblocks, so even for device images
that have been destructively truncated or have an unusually high number of
segments, the mount operation may succeed.
This causes out-of-bounds block I/O on file system block reads or log
writes to the segments, the latter in particular causing
"a_ops->writepages" to repeatedly fail, resulting in sync_inodes_sb() to
hang.
Fix this issue by checking the number of segments stored in the superblock
and avoiding mounting devices that can cause out-of-bounds accesses. To
eliminate the possibility of overflow when calculating the number of
blocks required for the device from the number of segments, this also adds
a helper function to calculate the upper bound on the number of segments
and inserts a check using it.

It's trivial to trigger a use-after-free bug in the ocfs2 quotas code using
fstest generic/452. After a read-only remount, quotas are suspended and
ocfs2_mem_dqinfo is freed through ->ocfs2_local_free_info(). When unmounting
the filesystem, an UAF access to the oinfo will eventually cause a crash.

It turns out that alloc_pages_bulk_array() does not treat the page_array
parameter as an output parameter, but rather reads the array and skips any
entries that have already been allocated.
This is somewhat unexpected and breaks this test, as we allocate the pages
array uninitialised on the assumption it will be overwritten.
As a result, the test was referencing uninitialised data and causing the
PFN to not be valid and thus a WARN_ON() followed by a null pointer deref
and panic.
In addition, this is an array of pointers not of struct page objects, so we
need only allocate an array with elements of pointer size.
We solve both problems by simply using kcalloc() and referencing
sizeof(struct page *) rather than sizeof(struct page).

Syzbot reports that in its stress test for resize ioctl, the log writing
function nilfs_segctor_do_construct hits a WARN_ON in
nilfs_segctor_truncate_segments().
It turned out that there is a problem with the current implementation of
the resize ioctl, which changes the writable range on the device (the
range of allocatable segments) at the end of the resize process.
This order is necessary for file system expansion to avoid corrupting the
superblock at trailing edge. However, in the case of a file system
shrink, if log writes occur after truncating out-of-bounds trailing
segments and before the resize is complete, segments may be allocated from
the truncated space.
The userspace resize tool was fine as it limits the range of allocatable
segments before performing the resize, but it can run into this issue if
the resize ioctl is called alone.
Fix this issue by changing nilfs_sufile_resize() to update the range of
allocatable segments immediately after successful truncation of segment
space in case of file system shrink.

Patch series "kexec: Fix kexec_file_load for llvm16 with PGO", v7.
When upreving llvm I realised that kexec stopped working on my test
platform.
The reason seems to be that due to PGO there are multiple .text sections
on the purgatory, and kexec does not supports that.
This patch (of 4):
Clang16 links the purgatory text in two sections when PGO is in use:
[ 1] .text PROGBITS 0000000000000000 00000040
00000000000011a1 0000000000000000 AX 0 0 16
[ 2] .rela.text RELA 0000000000000000 00003498
0000000000000648 0000000000000018 I 24 1 8
...
[17] .text.hot. PROGBITS 0000000000000000 00003220
000000000000020b 0000000000000000 AX 0 0 1
[18] .rela.text.hot. RELA 0000000000000000 00004428
0000000000000078 0000000000000018 I 24 17 8
And both of them have their range [sh_addr ... sh_addr+sh_size] on the
area pointed by `e_entry`.
This causes that image->start is calculated twice, once for .text and
another time for .text.hot. The second calculation leaves image->start
in a random location.
Because of this, the system crashes immediately after:

We used to not pass in the pgoff correctly when register/unregister uffd
regions, it caused incorrect behavior on vma merging and can cause
mergeable vmas being separate after ioctls return.
For example, when we have:
vma1(range 0-9, with uffd), vma2(range 10-19, no uffd)
Then someone unregisters uffd on range (5-9), it should logically become:
vma1(range 0-4, with uffd), vma2(range 5-19, no uffd)
But with current code we'll have:
vma1(range 0-4, with uffd), vma3(range 5-9, no uffd), vma2(range 10-19, no uffd)
This patch allows such merge to happen correctly before ioctl returns.
This behavior seems to have existed since the 1st day of uffd. Since
pgoff for vma_merge() is only used to identify the possibility of vma
merging, meanwhile here what we did was always passing in a pgoff smaller
than what we should, so there should have no other side effect besides not
merging it. Let's still tentatively copy stable for this, even though I
don't see anything will go wrong besides vma being split (which is mostly
not user visible).

Patch series "mm/uffd: Fix vma merge/split", v2.
This series contains two patches that fix vma merge/split for userfaultfd
on two separate issues.
Patch 1 fixes a regression since 6.1+ due to something we overlooked when
converting to maple tree apis. The plan is we use patch 1 to replace the
commit "2f628010799e (mm: userfaultfd: avoid passing an invalid range to
vma_merge())" in mm-hostfixes-unstable tree if possible, so as to bring
uffd vma operations back aligned with the rest code again.
Patch 2 fixes a long standing issue that vma can be left unmerged even if
we can for either uffd register or unregister.
Many thanks to Lorenzo on either noticing this issue from the assert
movement patch, looking at this problem, and also provided a reproducer on
the unmerged vma issue [1].
[1] https://gist.github.com/lorenzo-stoakes/a11a10f5f479e7a977fc456331266e0e
This patch (of 2):
It seems vma merging with uffd paths is broken with either
register/unregister, where right now we can feed wrong parameters to
vma_merge() and it's found by recent patch which moved asserts upwards in
vma_merge() by Lorenzo Stoakes:
https://lore.kernel.org/all/ZFunF7DmMdK05MoF@FVFF77S0Q05N.cambridge.arm.com/
It's possible that "start" is contained within vma but not clamped to its
start. We need to convert this into either "cannot merge" case or "can
merge" case 4 which permits subdivision of prev by assigning vma to prev.
As we loop, each subsequent VMA will be clamped to the start.
This patch will eliminate the report and make sure vma_merge() calls will
become legal again.
One thing to mention is that the "Fixes: 29417d292bd0" below is there only
to help explain where the warning can start to trigger, the real commit to
fix should be 69dbe6daf1. Commit 29417d292b helps us to identify the
issue, but unfortunately we may want to keep it in Fixes too just to ease
kernel backporters for easier tracking.

The xarray.c file contains the only call to radix_tree_node_rcu_free(),
and it comes with its own extern declaration for it. This means the
function definition causes a missing-prototype warning:
lib/radix-tree.c:288:6: error: no previous prototype for 'radix_tree_node_rcu_free' [-Werror=missing-prototypes]
Instead, move the declaration for this function to a new header that can
be included by both, and do the same for the radix_tree_node_cachep
variable that has the same underlying problem but does not cause a warning
with gcc.

A syzbot fault injection test reported that nilfs_btnode_create_block, a
helper function that allocates a new node block for b-trees, causes a
kernel BUG for disk images where the file system block size is smaller
than the page size.
This was due to unexpected flags on the newly allocated buffer head, and
it turned out to be because the buffer flags were not cleared by
nilfs_btnode_abort_change_key() after an error occurred during a b-tree
update operation and the buffer was later reused in that state.
Fix this issue by using nilfs_btnode_delete() to abandon the unused
preallocated buffer in nilfs_btnode_abort_change_key().

User events:
- Use long instead of int for storing the enable set/clear bit, as it was
found that big endian machines could end up using the wrong bits.
- Split allocating mm and attaching it. This keeps the allocation separate
from the registration and avoids various races.
- Remove RCU locking around pin_user_pages_remote() as that can schedule. The
RCU protection is no longer needed with the above split of mm allocation and
attaching.
- Rename the "link" fields of the various structs to something more
meaningful.
- Add comments around user_event_mm struct usage and locking requirements.
Timerlat tracer:
- Fix missed wakeup of timerlat thread caused by the timerlat interrupt
triggering when tracing is off. The timer interrupt handler needs to always
wake up the timerlat thread regardless if tracing is enabled or not,
otherwise, it will never wake up.
Histograms:
- Fix regression of breaking the "stacktrace" modifier for variables. That
modifier cannot be used for values, but can be used for variables that are
passed from one histogram to the next. This was broken when adding the
restriction to values as the variable logic used the same code.
- Rename the special field "stacktrace" to "common_stacktrace". Special fields
(that are not actually part of the event, but can act just like event
fields, like 'comm' and 'timestamp') should be prefixed with 'common_' for
consistency. To keep backward compatibility, 'stacktrace' can still be used
(as with the special field 'cpu'), but can be overridden if the event has a
field called 'stacktrace'.
- Update the synthetic event selftests to use the new name (synthetic events
are created by histograms)
Tracing bootup selftests:
- Reorganize the code to keep artifacts of the selftests not compiled in when
selftests are not configured.
- Add various cond_resched() around the selftest code, as the softlock
watchdog was triggering much more often. It appears that the kernel runs
slower now with full debugging enabled.
- While debugging ftrace with ftrace (using an instance ring buffer instead of
the top level one), I found that the selftests were disabling prints to the
debug instance. This should not happen, as the selftests only disable
printing to the main buffer as the selftests examine the main buffer to see
if it has what it expects, and prints can make the tests fail. Make the
selftests only disable printing to the toplevel buffer, and leave the
instance buffers alone.

"User events:
- Use long instead of int for storing the enable set/clear bit, as it
was found that big endian machines could end up using the wrong
bits.
- Split allocating mm and attaching it. This keeps the allocation
separate from the registration and avoids various races.
- Remove RCU locking around pin_user_pages_remote() as that can
schedule. The RCU protection is no longer needed with the above
split of mm allocation and attaching.
- Rename the "link" fields of the various structs to something more
meaningful.
- Add comments around user_event_mm struct usage and locking
requirements.
Timerlat tracer:
- Fix missed wakeup of timerlat thread caused by the timerlat
interrupt triggering when tracing is off. The timer interrupt
handler needs to always wake up the timerlat thread regardless if
tracing is enabled or not, otherwise, it will never wake up.
Histograms:
- Fix regression of breaking the "stacktrace" modifier for variables.
That modifier cannot be used for values, but can be used for
variables that are passed from one histogram to the next. This was
broken when adding the restriction to values as the variable logic
used the same code.
- Rename the special field "stacktrace" to "common_stacktrace".
Special fields (that are not actually part of the event, but can
act just like event fields, like 'comm' and 'timestamp') should be
prefixed with 'common_' for consistency. To keep backward
compatibility, 'stacktrace' can still be used (as with the special
field 'cpu'), but can be overridden if the event has a field called
'stacktrace'.
- Update the synthetic event selftests to use the new name (synthetic
events are created by histograms)
Tracing bootup selftests:
- Reorganize the code to keep artifacts of the selftests not compiled
in when selftests are not configured.
- Add various cond_resched() around the selftest code, as the
softlock watchdog was triggering much more often. It appears that
the kernel runs slower now with full debugging enabled.
- While debugging ftrace with ftrace (using an instance ring buffer
instead of the top level one), I found that the selftests were
disabling prints to the debug instance.
This should not happen, as the selftests only disable printing to
the main buffer as the selftests examine the main buffer to see if
it has what it expects, and prints can make the tests fail.
Make the selftests only disable printing to the toplevel buffer,
and leave the instance buffers alone"

This reverts commit 9828ed3f69.
Sadly, it does seem to cause failures to load modules. Johan Hovold reports:
"This change breaks module loading during boot on the Lenovo Thinkpad
X13s (aarch64).
Specifically it results in indefinite probe deferral of the display
and USB (ethernet) which makes it a pain to debug. Typing in the dark
to acquire some logs reveals that other modules are missing as well"
Since this was applied late as a "let's try this", I'm reverting it
asap, and we can try to figure out what goes wrong later. The excessive
parallel module loading problem is annoying, but not noticeable in
normal situations, and this was only meant as an optimistic workaround
for a user-space bug.
One possible solution may be to do the optimistic exclusive open first,
and then use a lock to serialize loading if that fails.

When all kernel debugging is enabled (lockdep, KSAN, etc), the function
graph enabling and disabling can take several seconds to complete. The
function_graph selftest enables and disables function graph tracing
several times. With full debugging enabled, the soft lockup watchdog was
triggering because the selftest was running without ever scheduling.
Add cond_resched() throughout the test to make sure it does not trigger
the soft lockup detector.

The tracing_selftest_running and tracing_selftest_disabled variables were
to keep trace_printk() and other writes from affecting the tracing
selftests, as the tracing selftests would examine the ring buffer to see
if it contained what it expected or not. trace_printk() and friends could
add to the ring buffer and cause the selftests to fail (and then disable
the tracer that was being tested). To keep that from happening, these
variables were added and would keep trace_printk() and friends from
writing to the ring buffer while the tests were going on.
But this was only the top level ring buffer (owned by the global_trace
instance). There is no reason to prevent writing into ring buffers of
other instances via the trace_array_printk() and friends. For the
functions that could be used by other instances, check if the global_trace
is the tracer instance that is being written to before deciding to not
allow the write.

As there are more and more internal selftests being added to the Linux
kernel (KSAN, lockdep, etc) the selftests are taking longer to run when
these are enabled. Add a cond_resched() to the calling of
do_run_tracer_selftest() to force a schedule if NEED_RESCHED is set,
otherwise the soft lockup watchdog may trigger on boot up.

The variables tracing_selftest_running and tracing_selftest_disabled are
only used for when CONFIG_FTRACE_STARTUP_TEST is enabled. Make them only
visible within the selftest code. The setting of those variables are in
the register_tracer() call, and set in a location where they do not need
to be. Create a wrapper around run_tracer_selftest() called
do_run_tracer_selftest() which sets those variables, and have
register_tracer() call that instead.
Having those variables only set within the CONFIG_FTRACE_STARTUP_TEST
scope gets rid of them (and also the ability to remove testing against
them) when the startup tests are not enabled (most cases).

Pull compute express link fixes from Dan Williams:
"The 'media ready' series prevents the driver from acting on bad
capacity information, and it moves some checks earlier in the init
sequence which impacts topics in the queue for 6.5.
Additional hotplug testing uncovered a missing enable for memory
decode. A debug crash fix is also included.
Summary:
- Stop trusting capacity data before the "media ready" indication
- Add missing HDM decoder capability enable for the cold-plug case
- Fix a debug message induced crash"

There have not been a lot of fixes for for the soc tree in 6.4, but
these have been sitting here for too long.
For the devicetree side, there is one minor warning fix for vexpress,
the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
for the iMX8 clocks and its USB-3.0 gadget device, as well as board
specific fixes for regulators and the phy on some of the i.MX boards.
The microchip risc-v and arm32 maintainers now also add a shared
maintainer file entry for the arm64 parts.
The remaining fixes are all for firmware drivers, addressing mistakes in
the optee, scmi and ff-a firmware driver implementation, mostly in the
error handling code, incorrect use of the alloc_workqueue() interface in
SCMI, and compatibility with corner cases of the firmware implementation.

When media is not ready do not assume that the capacity information from
the identify command is valid, i.e. ->total_bytes
->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly
zero out the capacity resources and exit early.
Given zero-init of those fields this patch is functionally equivalent to
the prior state, but it improves readability and robustness going

I tried to streamline our user memory copy code fairly aggressively in
commit adfcf4231b ("x86: don't use REP_GOOD or ERMS for user memory
copies"), in order to then be able to clean up the code and inline the
modern FSRM case in commit 577e6a7fd5 ("x86: inline the 'rep movs' in
user copies for the FSRM case").
We had reports [1] of that causing regressions earlier with blogbench,
but that turned out to be a horrible benchmark for that case, and not a
sufficient reason for re-instating "rep movsb" on older machines.
However, now Eric Dumazet reported [2] a regression in performance that
seems to be a rather more real benchmark, where due to the removal of
"rep movs" a TCP stream over a 100Gbps network no longer reaches line
speed.
And it turns out that with the simplified the calling convention for the
non-FSRM case in commit 427fda2c8a ("x86: improve on the non-rep
'copy_user' function"), re-introducing the ERMS case is actually fairly
simple.
Of course, that "fairly simple" is glossing over several missteps due to
having to fight our assembler alternative code. This code really wanted
to rewrite a conditional branch to have two different targets, but that
made objtool sufficiently unhappy that this instead just ended up doing
a choice between "jump to the unrolled loop, or use 'rep movsb'
directly".
Let's see if somebody finds a case where the kernel memory copies also
care (see commit 68674f94ff: "x86: don't use REP_GOOD or ERMS for
small memory copies"). But Eric does argue that the user copies are
special because networking tries to copy up to 32KB at a time, if
order-3 pages allocations are possible.
In-kernel memory copies are typically small, unless they are the special
"copy pages at a time" kind that still use "rep movs".

Pull NVMe fix from Keith:
"nvme fixes for 6.4
One nvme quirk (Tatsuki)"
* tag 'nvme-6.4-2023-05-26' of git://git.infradead.org/nvme:
NVMe: Add MAXIO 1602 to bogus nid list.
Quite a few fixes to address set of assorted issues:
1. NULL pointer dereference if the ffa driver doesn't provide remove()
callback as it is currently executed unconditionally
2. FF-A core probe failure on systems with v1.0 firmware as the new
partition info get count flag is used unconditionally
3. Failure to register more than one logical partition or service within
the same physical partition as the device name contains only VM ID
which will be same for all but each will have unique UUID.
4. Rejection of certain memory interface transmissions by the receivers
(secure partitions) as few MBZ fields are non-zero due to lack of
explicit re-initialization of those fields
