Pull smb client fix from Steve French:
 "Add minor debugging improvement.

  The change improves ability to read a network trace to debug problems
  on encrypted connections which are very common (e.g. using wireshark
  or tcpdump).

  That works today with tools like 'smbinfo keys /mnt/file' but requires
  passing in a filename on the mount (see e.g. [1]), but it often makes
  more sense to just pass in the mount point path (ie a directory not a
  filename).

  So this fix was needed to debug some types of problems (an obvious
  example is on an encrypted connection failing operations on an empty
  share or with no files in the root of the directory) - so you can
  simply pass in the 'smbinfo keys <mntpoint>' and get the information
  that wireshark needs"

Dumping the enc/dec keys is a session wide operation.
And it should not matter if the ioctl was run on
a regular file or a directory.

Currently, we obtain the tcon pointer from the
cifs file handle. But since there's no dir open call
in cifs, this is not populated for dirs.

This change allows dumping of session keys using ioctl
even for directories. To do this, we'll now get the
tcon pointer from the superblock, and not from the file
handle.

     originally noticed, a more substantial refactoring of the API which
     ensures that all buses make the same assumptions will follow.

   - The generic regcache code had been forcing on async I/O which did
     not work with the new maple tree sync code when used with SPI.

     Since that was mainly for the rbtree cache and the assumptions
     about hardware that drove the choice are probably not true any more
     fix this by pushing the enablement of async down into the rbtree
     code.

     This probably also makes cache syncs for systems faster though it's
     not the point.

   - The test code was triggering use of the rbtree and maple tree
     caches with dynamic allocation of nodes since all the testing is
     with RAM backed caches with no I/O performance issues.

Problem:

The max_loop parameter is used for 2 different purposes:

1) initial number of loop devices to pre-create on init
2) maximum number of loop devices to add on access/open()

Historically, its default value (zero) caused 1) to create non-zero
number of devices (CONFIG_BLK_DEV_LOOP_MIN_COUNT), and no hard limit on
2) to add devices with autoloading.

However, the default value changed in commit 85c50197 ("loop: Fix
the max_loop commandline argument treatment when it is set to 0") to
CONFIG_BLK_DEV_LOOP_MIN_COUNT, for max_loop=0 not to pre-create devices.

That does improve 1), but unfortunately it breaks 2), as the default
behavior changed from no-limit to hard-limit.

Example:

For example, this userspace code broke for N >= CONFIG, if the user
relied on the default value 0 for max_loop:

    mknod("/dev/loopN");
    open("/dev/loopN");  // now fails with ENXIO

Though affected users may "fix" it with (loop.)max_loop=0, this means to
require a kernel parameter change on stable kernel update (that commit
Fixes: an old commit in stable).

Solution:

The original semantics for the default value in 2) can be applied if the
parameter is not set (ie, default behavior).

This still keeps the intended function in 1) and 2) if set, and that
commit's intended improvement in 1) if max_loop=0.

Before 85c50197:
  - default:     1) CONFIG devices   2) no limit
  - max_loop=0:  1) CONFIG devices   2) no limit
  - max_loop=X:  1) X devices        2) X limit

After 85c50197:
  - default:     1) CONFIG devices   2) CONFIG limit (*)
  - max_loop=0:  1) 0 devices (*)    2) no limit
  - max_loop=X:  1) X devices        2) X limit

This commit:
  - default:     1) CONFIG devices   2) no limit (*)
  - max_loop=0:  1) 0 devices        2) no limit
  - max_loop=X:  1) X devices        2) X limit

Future:

The issue/regression from that commit only affects code under the
CONFIG_BLOCK_LEGACY_AUTOLOAD deprecation guard, thus the fix too is
contained under it.

Once that deprecated functionality/code is removed, the purpose 2) of
max_loop (hard limit) is no longer in use, so the module parameter
description can be changed then.

Current code supposes that it is enough to provide forward progress by
just waking up one wait queue after one completion batch is done.

Unfortunately this way isn't enough, cause waiter can be added to wait
queue just after it is woken up.

Follows one example(64 depth, wake_batch is 8)

1) all 64 tags are active

2) in each wait queue, there is only one single waiter

3) each time one completion batch(8 completions) wakes up just one
   waiter in each wait queue, then immediately one new sleeper is added
   to this wait queue

4) after 64 completions, 8 waiters are wakeup, and there are still 8
   waiters in each wait queue

5) after another 8 active tags are completed, only one waiter can be
   wakeup, and the other 7 can't be waken up anymore.

Turns out it isn't easy to fix this problem, so simply wakeup enough
waiters for single batch.

This requires a bit of background.  Properly done a modeset driver's
unload/remove sequence should be

	drm_dev_unplug();
	drm_atomic_helper_shutdown();
	drm_dev_put();

The trouble is that the drm_dev_unplugged() checks are by design racy,
they do not synchronize against all outstanding ioctl.  This is because
those ioctl could block forever (both for modeset and for driver
specific ioctls), leading to deadlocks in hotunplug.  Instead the code
sections that touch the hardware need to be annotated with
drm_dev_enter/exit, to avoid accessing hardware resources after the
unload/remove has finished.

To avoid use-after-free issues all the involved userspace visible
objects are supposed to hold a reference on the underlying drm_device,
like drm_file does.

The issue now is that we missed one, the atomic modeset ioctl can be run
in a nonblocking fashion, and in that case it cannot rely on the implied
drm_device reference provided by the ioctl calling context.  This can
result in a use-after-free if an nonblocking atomic commit is carefully
raced against a driver unload.

Fix this by unconditionally grabbing a drm_device reference for any
drm_atomic_state structures.  Strictly speaking this isn't required for
blocking commits and TEST_ONLY calls, but it's the simpler approach.

Thanks to shanzhulig for the initial idea of grabbing an unconditional
reference, I just added comments, a condensed commit message and fixed a
minor potential issue in where exactly we drop the final reference.

The io_uring testcase is broken on IA-64 since commit d808459b
("io_uring: Adjust mapping wrt architecture aliasing requirements").

The reason is, that this commit introduced an own architecture
independend get_unmapped_area() search algorithm which finds on IA-64 a
memory region which is outside of the regular memory region used for
shared userspace mappings and which can't be used on that platform
due to aliasing.

To avoid similar problems on IA-64 and other platforms in the future,
it's better to switch back to the architecture-provided
get_unmapped_area() function and adjust the needed input parameters
before the call. Beside fixing the issue, the function now becomes
easier to understand and maintain.

This patch has been successfully tested with the io_uring testcase on
physical x86-64, ppc64le, IA-64 and PA-RISC machines. On PA-RISC the LTP
mmmap testcases did not report any regressions.

When we reconfigure the SVE vector length we discard the backing storage
for the SVE vectors and then reallocate on next SVE use, leaving the SME
specific state alone. This means that we do not enable SME traps if they
were already disabled. That means that userspace code can enter streaming
mode without trapping, putting the task in a state where if we try to save
the state of the task we will fault.

Since the ABI does not specify that changing the SVE vector length disturbs
SME state, and since SVE code may not be aware of SME code in the process,
we shouldn't simply discard any ZA state. Instead immediately reallocate
the storage for SVE, and disable SME if we change the SVE vector length
while there is no SME state active.

Disabling SME traps on SVE vector length changes would make the overall
code more complex since we would have a state where we have valid SME state
stored but might get a SME trap.

Pull networking fixes from Jakub Kicinski:
 "Including fixes from BPF, netfilter, bluetooth and CAN.

  Current release - regressions:

   - eth: r8169: multiple fixes for PCIe ASPM-related problems

   - vrf: fix RCU lockdep splat in output path

  Previous releases - regressions:

   - gso: fall back to SW segmenting with GSO_UDP_L4 dodgy bit set

   - dsa: mv88e6xxx: do a final check before timing out when polling

   - nf_tables: fix sleep in atomic in nft_chain_validate

  Previous releases - always broken:

   - sched: fix undoing tcf_bind_filter() in multiple classifiers

   - bpf, arm64: fix BTI type used for freplace attached functions

   - can: gs_usb: fix time stamp counter initialization

   - nft_set_pipapo: fix improper element removal (leading to UAF)

  Misc:

   - net: support STP on bridge in non-root netns, STP prevents packet
     loops so not supporting it results in freezing systems of
     unsuspecting users, and in turn very upset noises being made

   - fix kdoc warnings

   - annotate various bits of TCP state to prevent data races"

The flush bio may have data, may have no data (empty flush), we couldn't
calculate cost for empty flush bio. So we'd better just skip it for now.

Another side effect is that empty flush bio's bio_end_sector() is 0, cause
iocg->cursor reset to 0, may break the cost calculation of other bios.

This isn't good enough, since flush bio still consume the device bandwidth,
but flush request is special, can be merged randomly in the flush state
machine, we don't know how to calculate cost for it for now.

Its completion time also has flaws, which may include the pre-flush or
post-flush completion time, but I don't know if we need to fix that and
how to fix it.

Florian Westphal says:

====================
Netfilter fixes for net:

The following patchset contains Netfilter fixes for net:

1. Fix spurious -EEXIST error from userspace due to
   padding holes, this was broken since 4.9 days
   when 'ignore duplicate entries on insert' feature was
   added.

2. Fix a sched-while-atomic bug, present since 5.19.

3. Properly remove elements if they lack an "end range".
   nft userspace always sets an end range attribute, even
   when its the same as the start, but the abi doesn't
   have such a restriction. Always broken since it was
   added in 5.6, all three from myself.

4 + 5: Bound chain needs to be skipped in netns release
   and on rule flush paths, from Pablo Neira.

mdio_bus_init() and phy_driver_register() both have error paths, and if
those are ever hit, ethtool will have a stale pointer to the
phy_ethtool_phy_ops stub structure, which references memory from a
module that failed to load (phylib).

It is probably hard to force an error in this code path even manually,
but the error teardown path of phy_init() should be the same as
phy_exit(), which is now simply not the case.

tcp: add missing annotations

This series was inspired by one syzbot (KCSAN) report.

do_tcp_getsockopt() does not lock the socket, we need to
annotate most of the reads there (and other places as well).

This is a first round, another series will come later.
