Pull more io_uring updates from Jens Axboe:

 - Remove a leftover struct from when the cqwait registered waiting was
   transitioned to regions.

 - Fix for an issue introduced in this merge window, where nop->fd might
   be used uninitialized. Ensure it's always set.

 - Add capping of the task_work run in local task_work mode, to prevent
   bursty and long chains from adding too much latency.

 - Work around xa_store() leaving ->head non-NULL if it encounters an
   allocation error during storing. Just a debug trigger, and can go
   away once xa_store() behaves in a more expected way for this
   condition. Not a major thing as it basically requires fault injection
   to trigger it.

 - Fix a few mapping corner cases

 - Fix KCSAN complaint on reading the table size post unlock. Again not
   a "real" issue, but it's easy to silence by just keeping the reading
   inside the lock that protects it.

If a PCI device has an associated device_node with power supplies,
pci_bus_add_device() creates platform devices for use by pwrctrl.  When the
PCI device is removed, pci_stop_dev() uses of_find_device_by_node() to
locate the related platform device, then unregisters it.

But when we remove a PCI device with no associated device node,
dev_of_node(dev) is NULL, and of_find_device_by_node(NULL) returns the
first device with "dev->of_node == NULL".  The result is that we (a)
mistakenly unregister a completely unrelated platform device, leading to
issues like the first trace below, and (b) dereference the NULL pointer
from dev_of_node() when clearing OF_POPULATED, as in the second trace.

Unregister a platform device only if there is one associated with this PCI
device.  This resolves issues seen when doing:

  # echo 1 > /sys/bus/pci/devices/.../remove

Sample issue from unregistering the wrong platform device:

When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected,
cpu_max_bits_warn() generates a runtime warning similar as below when
showing /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit)
instead of NR_CPUS to iterate CPUs.

Pull char/misc/IIO/whatever driver subsystem updates from Greg KH:
 "Here is the 'big and hairy' char/misc/iio and other small driver
  subsystem updates for 6.13-rc1.

  Loads of things in here, and even a fun merge conflict!

   - rust misc driver bindings and other rust changes to make misc
     drivers actually possible.

     I think this is the tipping point, expect to see way more rust
     drivers going forward now that these bindings are present. Next
     merge window hopefully we will have pci and platform drivers
     working, which will fully enable almost all driver subsystems to
     start accepting (or at least getting) rust drivers.

     This is the end result of a lot of work from a lot of people,
     congrats to all of them for getting this far, you've proved many of
     us wrong in the best way possible, working code :)

   - IIO driver updates, too many to list individually, that subsystem
     keeps growing and growing...

   - Interconnect driver updates

   - nvmem driver updates

   - pwm driver updates

   - platform_driver::remove() fixups, loads of them

   - counter driver updates

   - misc driver updates (keba?)

   - binder driver updates and fixes

   - loads of other small char/misc/etc driver updates and additions,
     full details in the shortlog.

  All of these have been in linux-next for a while, with no other
  reported issues other than that merge conflict"

Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver changes for 6.13-rc1.

  Lots of changes this merge cycle, drivers removed and drivers added.
  Highlights include:

   - removals of the following staging drivers due to no forward
     progress and no one having either the hardware or the time/energy
     to deal with them anymore:
       - fieldbus
       - gdm724x
       - olpc_dcon
       - rtl8712
       - rts5208
       - vt6655
       - vt6656
     If anyone has this hardware and wants to work on the drivers, it
     can be an easy revert to get them back.

   - addition of the gpib driver subsystem. Lots of drivers for really
     old and semi-old interfaces to lab equipments. We expect lots of
     churn in these drivers as they get cleaned up to "working" order.

     These were added at the request of a user and the maintainer/author
     of them is helping out with the effort

   - loads and loads of tiny coding style cleanups for almost all
     staging drivers. Too many to list, see the shortlog for details.

Set new allocated bfqq to bic or remove freed bfqq from bic are both
protected by bfqd->lock, however bfq_limit_depth() is deferencing bfqq
from bic without the lock, this can lead to UAF if the io_context is
shared by multiple tasks.

For example, test bfq with io_uring can trigger following UAF in v6.6:

syzbot triggered the following WARN_ON:

WARNING: CPU: 0 PID: 16 at io_uring/tctx.c:51 __io_uring_free+0xfa/0x140 io_uring/tctx.c:51

which is the

WARN_ON_ONCE(!xa_empty(&tctx->xa));

sanity check in __io_uring_free() when a io_uring_task is going through
its final put. The syzbot test case includes injecting memory allocation
failures, and it very much looks like xa_store() can fail one of its
memory allocations and end up with ->head being non-NULL even though no
entries exist in the xarray.

Until this issue gets sorted out, work around it by attempting to
iterate entries in our xarray, and WARN_ON_ONCE() if one is found.

Vasily Gorbik authored 3 months ago and Heiko Carstens committed 3 months ago

This reverts commit ff123eb7.

Allowing large pages for KASAN shadow mappings isn't inherently wrong,
but adding POPULATE_KASAN_MAP_SHADOW to large_allowed() exposes an issue
in can_large_pud() and can_large_pmd().

Since commit d8073dc6 ("s390/mm: Allow large pages only for aligned
physical addresses"), both can_large_pud() and can_large_pmd() call _pa()
to check if large page physical addresses are aligned. However, _pa()
has a side effect: it allocates memory in POPULATE_KASAN_MAP_SHADOW
mode. This results in massive memory leaks.

The proper fix would be to address both large_allowed() and _pa()'s side
effects, but for now, revert this change to avoid the leaks.

Pull more tracing updates from Steven Rostedt:

 - Add trace flag for NEED_RESCHED_LAZY

   Now that NEED_RESCHED_LAZY is upstream, add it to the status bits of
   the common_flags. This will now show when the NEED_RESCHED_LAZY flag
   is set that is used for debugging latency issues in the kernel via a
   trace.

 - Remove leftover "__idx" variable when SRCU was removed from the
   tracepoint code

 - Add rcu_tasks_trace guard

   To add a guard() around the tracepoint code, a rcu_tasks_trace guard
   needs to be created first.

 - Remove __DO_TRACE() macro and just call __DO_TRACE_CALL() directly

   The DO_TRACE() macro has conditional locking depending on what was
   passed into the macro parameters. As the guts of the macro has been
   moved to __DO_TRACE_CALL() to handle static call logic, there's no
   reason to keep the __DO_TRACE() macro around.

   It is better to just do the locking in place without the conditionals
   and call __DO_TRACE_CALL() from those locations. The "cond" passed in
   can also be moved out of that macro. This simplifies the code.

 - Remove the "cond" from the system call tracepoint macros

   The "cond" variable was added to allow some tracepoints to check a
   condition within the static_branch (jump/nop) logic. The system calls
   do not need this. Removing it simplifies the code.

 - Replace scoped_guard() with just guard() in the tracepoint logic

   guard() works just as well as scoped_guard() in the tracepoint logic
   and the scoped_guard() causes some issues.
