Merge tag 'fscache-fixes-20220708' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull fscache fixes from David Howells:

 - Fix a check in fscache_wait_on_volume_collision() in which the
   polarity is reversed. It should complain if a volume is still marked
   acquisition-pending after 20s, but instead complains if the mark has
   been cleared (ie. the condition has cleared).

   Also switch an open-coded test of the ACQUIRE_PENDING volume flag to
   use the helper function for consistency.

 - Not a fix per se, but neaten the code by using a helper to check for
   the DROPPED state.

 - Fix cachefiles's support for erofs to only flush requests associated
   with a released control file, not all requests.

 - Fix a race between one process invalidating an object in the cache
   and another process trying to look it up.

Linus Torvalds 086ff84617 fbdev fixes and updates for kernel v5.19-rc6:
fbcon now prevents switching to screen resolutions which are smaller
 than the font size, and prevents enabling a font which is bigger than
 the current screen resolution. This fixes vmalloc-out-of-bounds accesses
 found by KASAN.
 
 Guiling Deng fixed a bug where the centered fbdev logo wasn't displayed
 correctly if the screen size matched the logo size.
 
 Hsin-Yi Wang provided a patch to include errno.h to fix build when
 CONFIG_OF isn't enabled.

Linus Torvalds a382f8fee4 signal handling: don't use BUG_ON() for debugging
These are indeed "should not happen" situations, but it turns out recent
changes made the 'task_is_stopped_or_trace()' case trigger (fix for that
exists, is pending more testing), and the BUG_ON() makes it
unnecessarily hard to actually debug for no good reason.

It's been that way for a long time, but let's make it clear: BUG_ON() is
not good for debugging, and should never be used in situations where you
could just say "this shouldn't happen, but we can continue".

Use WARN_ON_ONCE() instead to make sure it gets logged, and then just
continue running.  Instead of making the system basically unusuable
because you crashed the machine while potentially holding some very core
locks (eg this function is commonly called while holding 'tasklist_lock'
for writing).

Qi Hu 112380996a LoongArch: Remove obsolete mentions of vcsr
The `vcsr` only exists in the old hardware design, it isn't used in any
shipped hardware from Loongson-3A5000 on. Both scalar FP and LSX/LASX
instructions use the `fcsr` as their control and status registers now.
For example, the RM control bit in fcsr0 is shared by FP, LSX and LASX
instructions.

Particularly, fcsr16 to fcsr31 are reserved for LSX/LASX now, access to
these registers has no visible effect if LSX/LASX is enabled, and will
cause SXD/ASXD exceptions if LSX/LASX is not enabled.

So, mentions of vcsr are obsolete in the first place (it was just used
for debugging), let's remove them.

Lukas Bulwahn 7fd6ef61a5 LoongArch: Drop these obsolete selects in Kconfig
Commit fa96b57c14 ("LoongArch: Add build infrastructure") adds the new
file arch/loongarch/Kconfig.

As the work on LoongArch was probably quite some time under development,
various config symbols have changed and disappeared from the time of
initial writing of the Kconfig file and its inclusion in the repository.

The following four commits:

  commit c126a53c27 ("arch: remove GENERIC_FIND_FIRST_BIT entirely")
  commit 140c8180eb ("arch: remove HAVE_COPY_THREAD_TLS")
  commit aca52c3983 ("mm: remove CONFIG_HAVE_MEMBLOCK")
  commit 3f08a302f5 ("mm: remove CONFIG_HAVE_MEMBLOCK_NODE_MAP option")

remove the mentioned config symbol, and enable the intended setup by
default without configuration.

Drop these obsolete selects in loongarch's Kconfig.

Helge Deller e64242caef fbcon: Prevent that screen size is smaller than font size
We need to prevent that users configure a screen size which is smaller than the
currently selected font size. Otherwise rendering chars on the screen will
access memory outside the graphics memory region.

This patch adds a new function fbcon_modechange_possible() which
implements this check and which later may be extended with other checks
if necessary.  The new function is called from the FBIOPUT_VSCREENINFO
ioctl handler in fbmem.c, which will return -EINVAL if userspace asked
for a too small screen size.

Jakub Kicinski 07266d0663 Merge branch 'wireguard-patches-for-5-19-rc6'
Jason A. Donenfeld says:

====================
wireguard patches for 5.19-rc6

1) A few small fixups to the selftests, per usual. Of particular note is
   a fix for a test flake that occurred on especially fast systems that
   boot in less than a second.

2) An addition during this cycle of some s390 crypto interacted with the
   way wireguard selects dependencies, resulting in linker errors
   reported by the kernel test robot. So Vladis sent in a patch for
   that, which also required a small preparatory fix moving some Kconfig
   symbols around.

Jason A. Donenfeld b7133757da crypto: s390 - do not depend on CRYPTO_HW for SIMD implementations
Various accelerated software implementation Kconfig values for S390 were
mistakenly placed into drivers/crypto/Kconfig, even though they're
mainly just SIMD code and live in arch/s390/crypto/ like usual. This
gives them the very unusual dependency on CRYPTO_HW, which leads to
problems elsewhere.

This patch fixes the issue by moving the Kconfig values for non-hardware
drivers into the usual place in crypto/Kconfig.

Not all platforms have an RTC, and rather than trying to force one into
each, it's much easier to just set a fixed time. This is necessary
because WireGuard's latest handshakes parameter is returned in wallclock
time, and if the system time isn't set, and the system is really fast,
then this returns 0, which trips the test.

Turning this on requires setting CONFIG_COMPAT_32BIT_TIME=y, as musl
doesn't support settimeofday without it.

Duoming Zhou 148ca04518 net: rose: fix UAF bug caused by rose_t0timer_expiry
There are UAF bugs caused by rose_t0timer_expiry(). The
root cause is that del_timer() could not stop the timer
handler that is running and there is no synchronization.
One of the race conditions is shown below:

    (thread 1)             |        (thread 2)
                           | rose_device_event
                           |   rose_rt_device_down
                           |     rose_remove_neigh
rose_t0timer_expiry        |       rose_stop_t0timer(rose_neigh)
  ...                      |         del_timer(&neigh->t0timer)
                           |         kfree(rose_neigh) //[1]FREE
  neigh->dce_mode //[2]USE |

The rose_neigh is deallocated in position [1] and use in
position [2].

The crash trace triggered by POC is like below:

BUG: KASAN: use-after-free in expire_timers+0x144/0x320
Write of size 8 at addr ffff888009b19658 by task swapper/0/0

This patch changes rose_stop_ftimer() and rose_stop_t0timer()
in rose_remove_neigh() to del_timer_sync() in order that the
timer handler could be finished before the resources such as
rose_neigh and so on are deallocated. As a result, the UAF
bugs could be mitigated.
