Patch series "mm: vma flag tweaks".
The ongoing work around introducing non-system word VMA flags has
introduced a number of helper functions and macros to make life easier
when working with these flags and to make conversions from the legacy use
of VM_xxx flags more straightforward.
This series improves these to reduce confusion as to what they do and to
improve consistency and readability.
Firstly the series renames vma_flags_test() to vma_flags_test_any() to
make it abundantly clear that this function tests whether any of the flags
are set (as opposed to vma_flags_test_all()).
It then renames vma_desc_test_flags() to vma_desc_test_any() for the same
reason. Note that we drop the 'flags' suffix here, as
vma_desc_test_any_flags() would be cumbersome and 'test' implies a flag
test.
Similarly, we rename vma_test_all_flags() to vma_test_all() for
consistency.
Next, we have a couple of instances (erofs, zonefs) where we are now
testing for vma_desc_test_any(desc, VMA_SHARED_BIT) &&
vma_desc_test_any(desc, VMA_MAYWRITE_BIT).
This is silly, so this series introduces vma_desc_test_all() so these
callers can instead invoke vma_desc_test_all(desc, VMA_SHARED_BIT,
VMA_MAYWRITE_BIT).
We then observe that quite a few instances of vma_flags_test_any() and
vma_desc_test_any() are in fact only testing against a single flag.
Using the _any() variant here is just confusing - 'any' of single item
reads strangely and is liable to cause confusion.
So in these instances the series reintroduces vma_flags_test() and
vma_desc_test() as helpers which test against a single flag.
The fact that vma_flags_t is a struct and that vma_flag_t utilises sparse
to avoid confusion with vm_flags_t makes it impossible for a user to
misuse these helpers without it getting flagged somewhere.
The series also updates __mk_vma_flags() and functions invoked by it to
explicitly mark them always inline to match expectation and to be
consistent with other VMA flag helpers.
It also renames vma_flag_set() to vma_flags_set_flag() (a function only
used by __mk_vma_flags()) to be consistent with other VMA flag helpers.
Finally it updates the VMA tests for each of these changes, and introduces
explicit tests for vma_flags_test() and vma_desc_test() to assert that
they behave as expected.
This patch (of 6):
On reflection, it's confusing to have vma_flags_test() and
vma_desc_test_flags() test whether any comma-separated VMA flag bit is
set, while also having vma_flags_test_all() and vma_test_all_flags()
separately test whether all flags are set.
Firstly, rename vma_flags_test() to vma_flags_test_any() to eliminate this
confusion.
Secondly, since the VMA descriptor flag functions are becoming rather
cumbersome, prefer vma_desc_test*() to vma_desc_test_flags*(), and also
rename vma_desc_test_flags() to vma_desc_test_any().
Finally, rename vma_test_all_flags() to vma_test_all() to keep the
VMA-specific helper consistent with the VMA descriptor naming convention
and to help avoid confusion vs. vma_flags_test_all().
While we're here, also update whitespace to be consistent in helper
functions.

"This mostly revolves around getting the driver to behave when the IPMI
device misbehaves. Past attempts have not worked very well because I
didn't have hardware I could make do this, and AI was fairly useless
for help on this.
So I modified qemu and my test suite so I could reproduce a
misbehaving IPMI device, and with that I was able to fix the issues"

This config option goes way back - it used to be an internal debug
option to random.c (at that point called DEBUG_RANDOM_BOOT), then was
renamed and exposed as a config option as CONFIG_WARN_UNSEEDED_RANDOM,
and then further renamed to the current CONFIG_WARN_ALL_UNSEEDED_RANDOM.
It was all done with the best of intentions: the more limited
rate-limited reports were reporting some cases, but if you wanted to see
all the gory details, you'd enable this "ALL" option.
However, it turns out - perhaps not surprisingly - that when people
don't care about and fix the first rate-limited cases, they most
certainly don't care about any others either, and so warning about all
of them isn't actually helping anything.
And the non-ratelimited reporting causes problems, where well-meaning
people enable debug options, but the excessive flood of messages that
nobody cares about will hide actual real information when things go
wrong.
I just got a kernel bug report (which had nothing to do with randomness)
where two thirds of the the truncated dmesg was just variations of
random: get_random_u32 called from __get_random_u32_below+0x10/0x70 with crng_init=0
and in the process early boot messages had been lost (in addition to
making the messages that _hadn't_ been lost harder to read).
The proper way to find these things for the hypothetical developer that
cares - if such a person exists - is almost certainly with boot time
tracing. That gives you the option to get call graphs etc too, which is
likely a requirement for fixing any problems anyway.
See Documentation/trace/boottime-trace.rst for that option.
And if we for some reason do want to re-introduce actual printing of
these things, it will need to have some uniqueness filtering rather than
this "just print it all" model.

There is a race on checking the state in the sender, it needs to be
checked under a lock. But you also need a check to avoid issues with
a misbehaving BMC for run to completion mode. So leave the check at
the beginning for run to completion, and add a check under the lock
to avoid the race.

It used to be, until recently, that the sender operation on the low
level interfaces would not fail. That's not the case any more with
recent changes.
So check the return value from the sender operation, and propagate it
back up from there and handle the errors in all places.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.
As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Pull irq cleanups from Thomas Gleixner:
"A series of treewide cleanups to ensure interrupt request consistency.
- Add the missing IRQF_COND_ONESHOT flag to devm_request_irq()
This is inconsistent vs request_irq() and causes the same issues
which where addressed with the introduction of this flag
- Cleanup IRQF_ONESHOT and IRQF_NO_THREAD usage
Quite some drivers have inconsistent interrupt request flags
related to interrupt threading namely IRQF_ONESHOT and
IRQF_NO_THREAD. This leads to warnings and/or malfunction when
forced interrupt threading is enabled.
- Remove stub primary (hard interrupt) handlers
A bunch of drivers implement a stub primary (hard interrupt)
handler which just returns IRQ_WAKE_THREAD. The same functionality
is provided by the core code when the primary handler argument of
request_thread_irq() is set to NULL"

Pull crypto library updates from Eric Biggers:
- Add support for verifying ML-DSA signatures.
ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a
recently-standardized post-quantum (quantum-resistant) signature
algorithm. It was known as Dilithium pre-standardization.
The first use case in the kernel will be module signing. But there
are also other users of RSA and ECDSA signatures in the kernel that
might want to upgrade to ML-DSA eventually.
- Improve the AES library:
- Make the AES key expansion and single block encryption and
decryption functions use the architecture-optimized AES code.
Enable these optimizations by default.
- Support preparing an AES key for encryption-only, using about
half as much memory as a bidirectional key.
- Replace the existing two generic implementations of AES with a
single one.
- Simplify how Adiantum message hashing is implemented. Remove the
"nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for
NH hashing, and enable optimizations by default.

Currently, hwrng_fill is not cleared until the hwrng_fillfn() thread
exits. Since hwrng_unregister() reads hwrng_fill outside the rng_mutex
lock, a concurrent hwrng_unregister() may call kthread_stop() again on
the same task.
Additionally, if hwrng_unregister() is called immediately after
hwrng_register(), the stopped thread may have never been executed. Thus,
hwrng_fill remains dirty even after hwrng_unregister() returns. In this
case, subsequent calls to hwrng_register() will fail to start new
threads, and hwrng_unregister() will call kthread_stop() on the same
freed task. In both cases, a use-after-free occurs:
refcount_t: addition on 0; use-after-free.
WARNING: ... at lib/refcount.c:25 refcount_warn_saturate+0xec/0x1c0
Call Trace:
kthread_stop+0x181/0x360
hwrng_unregister+0x288/0x380
virtrng_remove+0xe3/0x200
This patch fixes the race by protecting the global hwrng_fill pointer
inside the rng_mutex lock, so that hwrng_fillfn() thread is stopped only
once, and calls to kthread_run() and kthread_stop() are serialized
with the lock held.
To avoid deadlock in hwrng_fillfn() while being stopped with the lock
held, we convert current_rng to RCU, so that get_current_rng() can read
current_rng without holding the lock. To remove the lock from put_rng(),
we also delay the actual cleanup into a work_struct.
Since get_current_rng() no longer returns ERR_PTR values, the IS_ERR()
checks are removed from its callers.
With hwrng_fill protected by the rng_mutex lock, hwrng_fillfn() can no
longer clear hwrng_fill itself. Therefore, if hwrng_fillfn() returns
directly after current_rng is dropped, kthread_stop() would be called on
a freed task_struct later. To fix this, hwrng_fillfn() calls schedule()
now to keep the task alive until being stopped. The kthread_stop() call
is also moved from hwrng_unregister() to drop_current_rng(), ensuring
kthread_stop() is called on all possible paths where current_rng becomes
NULL, so that the thread would not wait forever.

The analysis from Breno:
When the SMI sender returns an error, smi_work() delivers an error
response but then jumps back to restart without cleaning up properly:
1. intf->curr_msg is not cleared, so no new message is pulled
2. newmsg still points to the message, causing sender() to be called
again with the same message
3. If sender() fails again, deliver_err_response() is called with
the same recv_msg that was already queued for delivery
This causes list_add corruption ("list_add double add") because the
recv_msg is added to the user_msgs list twice. Subsequently, the
corrupted list leads to use-after-free when the memory is freed and
reused, and eventually a NULL pointer dereference when accessing
recv_msg->done.
The buggy sequence:
sender() fails
-> deliver_err_response(recv_msg) // recv_msg queued for delivery
-> goto restart // curr_msg not cleared!
sender() fails again (same message!)
-> deliver_err_response(recv_msg) // tries to queue same recv_msg
-> LIST CORRUPTION
Fix this by freeing the message and setting it to NULL on a send error.
Also, always free the newmsg on a send error, otherwise it will leak.

Passing IRQF_ONESHOT ensures that the interrupt source is masked until
the secondary (threaded) handler is done. If only a primary handler is
used then the flag makes no sense because the interrupt can not fire
(again) while its handler is running.
The flag also prevents force-threading of the primary handler and the
irq-core will warn about this.
Remove IRQF_ONESHOT from irqflags.

Airoha uses RAW mode to collect noise from the TRNG. These appear to
be unprocessed oscillations from the tero loop. For this reason, they
do not have a perfect distribution and entropy. Simple noise compression
reduces its size by 9%, so setting the quality to 900 seems reasonable.
The same value is used by the downstream driver.
Compare the size before and after compression:

Switch from the old AES library functions (which use struct
crypto_aes_ctx) to the new ones (which use struct aes_enckey). This
eliminates the unnecessary computation and caching of the decryption
round keys. The new AES en/decryption functions are also much faster
and use AES instructions when supported by the CPU.
Note that in addition to the change in the key preparation function and
the key struct type itself, the change in the type of the key struct
results in aes_encrypt() (which is temporarily a type-generic macro)
calling the new encryption function rather than the old one.
