If e.g. get_user() triggers a page fault and a fatal signal is caught, we might
end up with handle_mm_fault() returning VM_FAULT_RETRY and not doing anything

that would repeat the entire thing without making any progress; what we need

genirq/msi, platform-msi: Ensure that MSI descriptors are unreferenced

Miquel reported a warning in the MSI core which is triggered when
interrupts are freed via platform_msi_device_domain_free().

This code got reworked to use core functions for freeing the MSI
descriptors, but nothing took care to clear the msi_desc->irq entry, which
then triggers the warning in msi_free_msi_desc() which uses desc->irq to
validate that the descriptor has been torn down. The same issue exists in
msi_domain_populate_irqs().

Up to the point that msi_free_msi_descs() grew a warning for this case,
this went un-noticed.

Provide the counterpart of msi_domain_populate_irqs() and invoke it in
platform_msi_device_domain_free() before freeing the interrupts and MSI
descriptors and also in the error path of msi_domain_populate_irqs().

20 months agos390/kprobes: fix current_kprobe never cleared after kprobes reenter
Vasily Gorbik [Wed, 1 Mar 2023 16:58:06 +0000 (17:58 +0100)]
s390/kprobes: fix current_kprobe never cleared after kprobes reenter

Recent test_kprobe_missed kprobes kunit test uncovers the following
problem. Once kprobe is triggered from another kprobe (kprobe reenter),
all future kprobes on this cpu are considered as kprobe reenter, thus
pre_handler and post_handler are not being called and kprobes are counted
as "missed".

Commit b9599798f953 ("[S390] kprobes: activation and deactivation")
introduced a simpler scheme for kprobes (de)activation and status
tracking by using push_kprobe/pop_kprobe, which supposed to work for
both initial kprobe entry as well as kprobe reentry and helps to avoid
handling those two cases differently. The problem is that a sequence of
calls in case of kprobes reenter:
push_kprobe() <- NULL (current_kprobe)
push_kprobe() <- kprobe1 (current_kprobe)
pop_kprobe() -> kprobe1 (current_kprobe)
pop_kprobe() -> kprobe1 (current_kprobe)
leaves "kprobe1" as "current_kprobe" on this cpu, instead of setting it
to NULL. In fact push_kprobe/pop_kprobe can only store a single state
(there is just one prev_kprobe in kprobe_ctlblk). Which is a hack but
sufficient, there is no need to have another prev_kprobe just to store
NULL. To make a simple and backportable fix simply reset "prev_kprobe"
when kprobe is poped from this "stack". No need to worry about
"kprobe_status" in this case, because its value is only checked when
current_kprobe != NULL.

The reason for this error report is that kprobes handling code failed
to restore irqs.

The problem is that when kprobe is triggered from another kprobe
post_handler current sequence of enable_singlestep / disable_singlestep
is the following:
enable_singlestep  <- original kprobe (saves kprobe_saved_imask)
enable_singlestep  <- kprobe triggered from post_handler (clobbers kprobe_saved_imask)
disable_singlestep <- kprobe triggered from post_handler (restores kprobe_saved_imask)
disable_singlestep <- original kprobe (restores wrong clobbered kprobe_saved_imask)

There is just one kprobe_ctlblk per cpu and both calls saves and
loads irq mask to kprobe_saved_imask. To fix the problem simply move
resume_execution (which calls disable_singlestep) before calling
post_handler. This also fixes the problem that post_handler is called
with pt_regs which were not yet adjusted after single-stepping.

20 months agodrm/amd/display: Don't restrict bpc to 8 bpc

drm/amd/display: Don't restrict bpc to 8 bpc

This will let us pass the kms_hdr.bpc_switch IGT
test.

The reason the bpc restriction was required is
historical. At one point in time we were not falling
back to a lower bpc when we didn't have enough
bandwidth for the maximum bpc reported by a display.
This meant that we couldn't enable some high refresh
modes unless we limitted the bpc.

Starting with this patch the issue is fixed:
commit cbd14ae7ea93 ("drm/amd/display: Fix
incorrectly pruned modes with deep color")

This patch implemented a fallback mechanism if mode
validation failed at the max bpc. This means users
now automatically get all modes that can be supported
by at least 6 bpc. The driver will enable the mode
with the highest possible bpc that is supported by
the display.

v2:
 - explain why this is no longer needed (Michel)
 - refer to commit that fixed bpc fallback (Michel)

David Howells [Tue, 28 Feb 2023 22:38:38 +0000 (22:38 +0000)]
cifs: Fix memory leak in direct I/O

When __cifs_readv() and __cifs_writev() extract pages from a user-backed
iterator into a BVEC-type iterator, they set ->bv_need_unpin to note
whether they need to unpin the pages later.  However, in both cases they
examine the BVEC-type iterator and not the source iterator - and so
bv_need_unpin doesn't get set and the pages are leaked.

I think this may be responsible for the generic/208 xfstest failing
occasionally with:

with the page refcount going negative.  This is less unlikely than it seems
because the page is being pinned, not simply got, and so the refcount
increased by 1024 each time, and so only needs to be called around ~2097152
for the refcount to go negative.

Further, the test program (aio-dio-invalidate-failure) uses a 32MiB static
buffer and all the PTEs covering it refer to the same page because it's
never written to.

The warning in try_grab_page():

then trips and prevents us ever using the page again for DIO at least.

20 months agocapability: just use a 'u64' instead of a 'u32[2]' array
Linus Torvalds [Tue, 28 Feb 2023 19:39:09 +0000 (11:39 -0800)]
capability: just use a 'u64' instead of a 'u32[2]' array

Back in 2008 we extended the capability bits from 32 to 64, and we did
it by extending the single 32-bit capability word from one word to an
array of two words.  It was then obfuscated by hiding the "2" behind two
macro expansions, with the reasoning being that maybe it gets extended
further some day.

That reasoning may have been valid at the time, but the last thing we
want to do is to extend the capability set any more.  And the array of
values not only causes source code oddities (with loops to deal with
it), but also results in worse code generation.  It's a lose-lose
situation.

So just change the 'u32[2]' into a 'u64' and be done with it.

We still have to deal with the fact that the user space interface is
designed around an array of these 32-bit values, but that was the case
before too, since the array layouts were different (ie user space
doesn't use an array of 32-bit values for individual capability masks,
but an array of 32-bit slices of multiple masks).

So that marshalling of data is actually simplified too, even if it does
remain somewhat obscure and odd.

This was all triggered by my reaction to the new "cap_isidentical()"
introduced recently.  By just using a saner data structure, it went from

unsigned __capi;
CAP_FOR_EACH_U32(__capi) {
if (a.cap[__capi] != b.cap[__capi])
return false;
}
return true;

to just being

return a.val == b.val;

instead.  Which is rather more obvious both to humans and to compilers.

drm/edid: Fix csync detailed mode parsing

Remove the bogus csync check and replace it with something that:
- triggers for all forms of csync, not just the basic analog variant
- actually populates the mode csync flags so that drivers can
  decide what to do with the mode

Originally the code tried to outright reject csync, but that
apparently broke some bogus LCD monitor that claimed to have
a detailed mode that uses analog csync, despite also claiming
the monitor only support separate sync:
https://bugzilla.redhat.com/show_bug.cgi?id=540024
Potentially that monitor should just be quirked or something.

Anyways, what we are dealing with now is some kind of funny i915
JSL machine with eDP where the panel claims to support a sensible
60Hz separate sync mode, and a 50Hz mode with bipolar analog
csync. The 50Hz mode does not work so we want to not use it.
Easiest way is to just correctly flag it as csync and the driver
will reject it.

TODO: or should we just reject any form of csync (or at least
the analog variants) for digital display interfaces?

riscv, lib: Fix Zbb strncmp

The Zbb optimized strncmp has two parts; a fast path that does XLEN/8B
per iteration, and a slow that does one byte per iteration.

The idea is to compare aligned XLEN chunks for most of strings, and do
the remainder tail in the slow path.

The Zbb strncmp has two issues in the fast path:

Incorrect remainder handling (wrong compare): Assume that the string
length is 9. On 64b systems, the fast path should do one iteration,
and one iteration in the slow path. Instead, both were done in the
fast path, which lead to incorrect results. An example:

  strncmp("/dev/vda", "/dev/", 5);

Correct by changing "bgt" to "bge".

Missing NULL checks in the second string: This could lead to incorrect
results for:

  strncmp("/dev/vda", "/dev/vda\0", 8);

Correct by adding an additional check.

Merge series from Claudiu Beznea <claudiu.beznea@microchip.com>:

To start capture on Microchip PDMC the enable bits for each supported
microphone need to be set. After this bit is set the PDMC starts to
receive data from microphones and it considers this data as valid data.
Thus if microphones are not ready the PDMC captures anyway data from its
lines. This data is interpreted by the human ear as poc noises.

To avoid this the following software workaround need to be applied when
starting capture:
1/ enable PDMC channel
2/ wait 150ms
3/ execute 16 dummy reads from RHR
4/ clear interrupts
5/ enable interrupts
6/ enable DMA channel

For this workaround to work step 6 need to be executed at the end.
For step 6 was added patch 1/3 from this series. With this, component
DAI driver sets its struct snd_soc_component_driver::start_dma_last = 1
and proper action is taken based on this flag when starting DAI trigger
vs DMA.

events can be generated appropriately for userspace but the custom control
in the MT8183 I2S DAI driver doesn't do that, fix it.

There is a lot of dev_info() logging in normal operation in the I2S DAI
driver, remove it to avoid spamming the console.

ASoC: mt6358: Remove undefined HPx Mux enumeration values

The HPx Mux enumerations define values 5, 6 and 7 but describe them as
"undefined" and map them to the value 0 on writing. Given the descriptions
and behaviour it seems that these values are invalid and should not be
present in the register, the current behaviour is detected as problematic
by mixer-test:

# # HPL Mux.0 expected 5 but read 0, is_volatile 0
# # HPL Mux.0 expected 6 but read 0, is_volatile 0
# # HPL Mux.0 expected 7 but read 0, is_volatile 0

Remove the values from the enumeration, this will prevent userspace setting
them.
