030f653078 parisc: fix crash with signals and alloca
I was debugging some crashes on parisc and I found out that there is a
crash possibility if a function using alloca is interrupted by a signal.
The reason for the crash is that the gcc alloca implementation leaves
garbage in the upper 32 bits of the sp register. This normally doesn't
matter (the upper bits are ignored because the PSW W-bit is clear),
however the signal delivery routine in the kernel uses full 64 bits of sp
and it fails with -EFAULT if the upper 32 bits are not zero.

I created this program that demonstrates the problem:

#include <stdlib.h>
#include <unistd.h>
#include <signal.h>
#include <alloca.h>

static __attribute__((noinline,noclone)) void aa(int *size)
{
	void * volatile p = alloca(-*size);
	while (1) ;
}

static void handler(int sig)
{
	write(1, "signal delivered\n", 17);
	_exit(0);
}

int main(void)
{
	int size = -0x100;
	signal(SIGALRM, handler);
	alarm(1);
	aa(&size);
}

If you compile it with optimizations, it will crash.
The "aa" function has this disassembly:

000106a0 <aa>:
   106a0:       08 03 02 41     copy r3,r1
   106a4:       08 1e 02 43     copy sp,r3
   106a8:       6f c1 00 80     stw,ma r1,40(sp)
   106ac:       37 dc 3f c1     ldo -20(sp),ret0
   106b0:       0c 7c 12 90     stw ret0,8(r3)
   106b4:       0f 40 10 9c     ldw 0(r26),ret0		; ret0 = 0x00000000FFFFFF00
   106b8:       97 9c 00 7e     subi 3f,ret0,ret0	; ret0 = 0xFFFFFFFF0000013F
   106bc:       d7 80 1c 1a     depwi 0,31,6,ret0	; ret0 = 0xFFFFFFFF00000100
   106c0:       0b 9e 0a 1e     add,l sp,ret0,sp	;   sp = 0xFFFFFFFFxxxxxxxx
   106c4:       e8 1f 1f f7     b,l,n 106c4 <aa+0x24>,r0

This patch fixes the bug by truncating the "usp" variable to 32 bits.

5f6e0fe01b parisc: Fix compile failure when building 64-bit kernel natively
Commit 23243c1ace ("arch: use cross_compiling to check whether it is
a cross build or not") broke 64-bit parisc builds on 32-bit parisc
systems.

Helge mentioned:
  - 64-bit parisc userspace is not supported yet [1]
  - hppa gcc does not support "-m64" flag [2]

That means, parisc developers working on a 32-bit parisc machine need
to use hppa64-linux-gnu-gcc (cross compiler) for building the 64-bit
parisc kernel.

After the offending commit, gcc is used in such a case because
both $(SRCARCH) and $(SUBARCH) are 'parisc', hence cross_compiling is
unset.

A correct way is to introduce ARCH=parisc64 because building the 64-bit
parisc kernel on a 32-bit parisc system is not exactly a native build,
but rather a semi-cross build.

d2f311ec91 HID: usbhid: Simplify code in hid_submit_ctrl()
This patch makes a small simplification to the code in
hid_submit_ctrl().  The test for maxpacket being > 0 is unnecessary,
because endpoint 0 always has a maxpacket value which is >= 8.

Furthermore, endpoint 0's maxpacket value is always a power of 2, so
instead of open-coding the round-to-next-multiple computation we can
call the optimized round_up() routine.

0a824efdb7 HID: usbhid: Fix warning caused by 0-length input reports
Syzbot found a warning caused by hid_submit_ctrl() submitting a
control request to transfer a 0-length input report:

	usb 1-1: BOGUS control dir, pipe 80000280 doesn't match bRequestType a1

(The warning message is a little difficult to understand.  It means
that the control request claims to be for an IN transfer but this
contradicts the USB spec, which requires 0-length control transfers
always to be in the OUT direction.)

Now, a zero-length report isn't good for anything and there's no
reason for a device to have one, but the fuzzer likes to pick out
these weird edge cases.  In the future, perhaps we will decide to
reject 0-length reports at probe time.  For now, the simplest approach
for avoiding these warnings is to pretend that the report actually has
length 1.

5049307d37 HID: usbhid: Fix flood of "control queue full" messages
[patch description by Alan Stern]

Commit 7652dd2c5c ("USB: core: Check buffer length matches wLength
for control transfers") causes control URB submissions to fail if the
transfer_buffer_length value disagrees with the setup packet's wLength
valuel.  Unfortunately, it turns out that the usbhid can trigger this
failure mode when it submits a control request for an input report: It
pads the transfer buffer size to a multiple of the maxpacket value but
does not increase wLength correspondingly.

These failures have caused problems for people using an APS UPC, in
the form of a flood of log messages resembling:

	hid-generic 0003:051D:0002.0002: control queue full

This patch fixes the problem by setting the wLength value equal to the
padded transfer_buffer_length value in hid_submit_ctrl().  As a nice
bonus, the code which stores the transfer_buffer_length value is now
shared between the two branches of an "if" statement, so it can be
de-duplicated.

15e20db2e0 io-wq: only exit on fatal signals

for communication, that can cause io-wq workers to spuriously exit

f95dc207b9 io-wq: split bounded and unbounded work into separate lists
We've got a few issues that all boil down to the fact that we have one
list of pending work items, yet two different types of workers to
serve them. This causes some oddities around workers switching type and
even hashed work vs regular work on the same bounded list.

Just separate them out cleanly, similarly to how we already do
accounting of what is running. That provides a clean separation and
removes some corner cases that can cause stalls when handling IO
that is punted to io-wq.

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

4cd67adc44 This tag contains habanalabs driver changes for v5.15:
- Add a new uAPI (under the cs ioctl) to enable to user to reserve
   signals and signal them from within its workloads, while the driver
   performs the waiting. This allows finer granularity of pipelining
   between the different engines and resource utilization.
 
 - Add a new uAPI (under the wait_for_cs ioctl) to allow waiting
   on multiple command submissions (workloads) at the same time. This
   is an optimization for the user process so it won't need to call
   multiple times to the wait_for_cs ioctl.
 
 - Add new feature of "state dump", which can be triggered through new
   debugfs node. This is a similar concept to the kernel panic dump.
   This new mechanism retrieves information from the device in case
   one of the workloads that was sent by the user got stuck. This is
   very helpful for debugging the hang.
 
 - Add a new debugfs node to perform lookup of user pointers that are
   mapped to habana device's pmmu.
 
 - Fix to the tracking of user process when running inside a container.
 
 - Allow user to map more than 4GB of memory to the device MMU in single
   IOCTL call.
 
 - Minimize number of register reads done in GAUDI during user operation.
 
 - Allow user to retrieve the device's server type that the device is
   connected to.
 
 - Several fixes to the code of waiting on interrupts on behalf of the
   user.
 
 - Fixes and improvements to the hint mechanism in our VA allocation.
 
 - Update the firmware header files to the latest version while
   maintaining backward compatibility with older firmware versions.
 
 - Multiple fixes to various bugs.

36e784a60b Merge branch 'mptcp-prevent-tcp_push-crash-and-selftest-temp-file-buildup'
Mat Martineau says:

====================
mptcp: Prevent tcp_push() crash and selftest temp file buildup

These are two fixes for the net tree, addressing separate issues.

Patch 1 addresses a divide-by-zero crash seen in syzkaller and also
reported by a user on the netdev list. This changes MPTCP code so
tcp_push() cannot be called with an invalid (0) mss_now value.

Patch 2 fixes a selftest temp file cleanup issue that consumes excessive
disk space when running repeated tests.

bfd862a7e9 selftests: mptcp: clean tmp files in simult_flows
'$cin' and '$sin' variables are local to a function: they are then not
available from the cleanup trap.

Instead, we need to use '$large' and '$small' that are not local and
defined just before setting the trap.

Without this patch, running this script in a loop might cause a:

  write: No space left on device

issue.

1094c6fe72 mptcp: fix possible divide by zero
Florian noted that if mptcp_alloc_tx_skb() allocation fails
in __mptcp_push_pending(), we can end-up invoking
mptcp_push_release()/tcp_push() with a zero mss, causing
a divide by 0 error.

This change addresses the issue refactoring the skb allocation
code checking if skb collapsing will happen for sure and doing
the skb allocation only after such check. Skb allocation will
now happen only after the call to tcp_send_mss() which
correctly initializes mss_now.

As side bonuses we now fill the skb tx cache only when needed,
and this also clean-up a bit the output path.

v1 -> v2:
 - use lockdep_assert_held_once() - Jakub
 - fix indentation - Jakub

0d290223a6 sound updates for 5.15-rc1
There are a few intensive changes in ALSA core side at this time that
 helped the significant code reduction.  Meanwhile we keep getting new
 stuff, so the total size still grows...
 Anyway, the below are some highlights in this development cycle.
 
 ALSA core:
 - New helpers to manage page allocations and card object with devres
 - Refactoring for memory allocation with wc-pages
 - A new PCM hardware flag SNDRV_PCM_INFO_EXPLICIT_SYNC for controlling
   the explicit sync of the stream control; it'll be used for ASoC SOF
   and non-coherent memory in future
 
 ASoC:
 - Lots of cleanups and improvements to the Intel drivers, including
   some new systems support
 - New support for AMD Vangoh, CUI CMM-4030D-261, Mediatek Mt8195,
   Renesas RZ/G2L Mediatek Mt8195, RealTek RT101P, Renesas RZ/G2L,
   Rockchip RK3568 S/PDIF
 
 USB-audio:
 - Re-organized the quirk handling and  a new option quirk_flags
 - Fix for a regression in 5.14 code change for JACK
 - Quirks for Sony WALKMAN, Digidesign mbox
 
 HD-audio:
 - Enhanced support for CS8409 codec
 - More consistent shutdown behavior with the runtime PM
 - The model option can accept the PCI or codec SSID as an alias
 - Quirks for ASUS ROG, HP Spectre x360
 
 Others:
 - Lots of code reduction in legacy drivers with devres helpers
 - FireWire MOTU 896HD support

ea7b4244b3 x86/setup: Explicitly include acpi.h
After commit 342f43af70 ("iscsi_ibft: fix crash due to KASLR physical
memory remapping") x86_64_defconfig shows the following errors:

  arch/x86/kernel/setup.c: In function ‘setup_arch’:
  arch/x86/kernel/setup.c:916:13: error: implicit declaration of function ‘acpi_mps_check’ [-Werror=implicit-function-declaration]
    916 |         if (acpi_mps_check()) {

   1110 |         acpi_table_upgrade();
        |         ^~~~~~~~~~~~~~~~~~
  [... more acpi noise ...]

acpi.h was being implicitly included from iscsi_ibft.h in this
configuration so the removal of that header means these functions have
no definition or declaration.

In most other configurations, <linux/acpi.h> continued to be included
through at least <linux/tboot.h> if CONFIG_INTEL_TXT was enabled, and
there were probably other implicit include paths too.

Add acpi.h explicitly so there is no more error, and so that we don't
continue to depend on these unreliable implicit include paths.

ebf435d3b5 IIO / Staging driver update for 5.15-rc1
Here is the big set of staging and IIO driver updates for 5.15-rc1.
 Also included in here are the counter driver subsystem updates as the
 IIO drivers needed them.
 
 Lots of churn in some staging drivers, we dropped the "old" rtl8188eu
 driver and replaced it with a newer version of the driver that had been
 maintained out-of-tree by Larry with the end goal of actually being able
 to get this driver out of staging eventually.  Despite that driver being
 "newer" the line count of this pull request is going up.
 
 Some drivers moved out of staging as well, which is always nice to see,
 that is why there are additions to the mfc and misc driver subsystems.
 All of these were acked by the various subsystem maintainers involved.
 
 But by far, as normal, it's coding style cleanups all over the
 drivers/staging/ tree in here.
 
 Full details of these changes are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 problems.

[ Note: the r8188eu merge clashed with commit 89939e8906 ("staging:

ecd9567314 fs: dlm: avoid comms shutdown delay in release_lockspace
When dlm_release_lockspace does active shutdown on connections to
other nodes, the active shutdown will wait for any exisitng passive
shutdowns to be resolved.  But, the sequence of operations during
dlm_release_lockspace can prevent the normal resolution of passive
shutdowns (processed normally by way of lockspace recovery.)
This disruption of passive shutdown handling can cause the active
shutdown to wait for a full timeout period, delaying the completion
of dlm_release_lockspace.

To fix this, make dlm_release_lockspace resolve existing passive
shutdowns (by calling dlm_clear_members earlier), before it does
active shutdowns.  The active shutdowns will not find any passive
shutdowns to wait for, and will not be delayed.

c6c3c5704b Driver core update for 5.15-rc1
Here is the big set of driver core patches for 5.15-rc1.
 
 These do change a number of different things across different
 subsystems, and because of that, there were 2 stable tags created that
 might have already come into your tree from different pulls that did the
 following
 	- changed the bus remove callback to return void
 	- sysfs iomem_get_mapping rework
 
 The latter one will cause a tiny merge issue with your tree, as there
 was a last-minute fix for this in 5.14 in your tree, but the fixup
 should be "obvious".  If you want me to provide a fixed merge for this,
 please let me know.
 
 Other than those two things, there's only a few small things in here:
 	- kernfs performance improvements for huge numbers of sysfs
 	  users at once
 	- tiny api cleanups
 	- other minor changes
 
 All of these have been in linux-next for a while with no reported
 problems, other than the before-mentioned merge issue.

053caa267f habanalabs: remove unnecessary device status check
Checking if the device is operational when entering the function to
wait for user interrupt is not something that is useful or necessary.

It is not done in any other wait_for_cs ioctl path.

If the device becomes non-operational during the wait, the reset
function will make sure the process wait is interrupted.

Instead, move the check to the beginning of hl_wait_ioctl(). It will
block any attempt to wait on CS or user interrupt once the device
is already marked as non-operational.

71731090ab habanalabs: add "in device creation" status
On init, the disabled state is cleared right before hw_init and that
causes the device to report on "Operational" state before the device
initialization is finished. Although the char device is not yet exposed
to the user at this stage, the sysfs entries are exposed.

This can cause errors in monitoring applications that use the sysfs
entries.

In order to avoid this, a new state "in device creation" is introduced
to ne reported when the device is not disabled but is still in init
flow.
