2dd0d98d62 USB/Thunderbolt fixes for 6.4-rc3
Here are some USB fixes for 6.4-rc3, as well as a driver core fix that
 resolves a memory leak that shows up in USB devices easier than other
 subsystems.
 
 Included in here are:
   - driver core memory leak as reported and tested by syzbot and
     developers
   - dwc3 driver fixes for reported problems
   - xhci driver fixes for reported problems
   - USB gadget driver reverts to resolve regressions
   - usbtmc driver fix for syzbot reported problem
   - thunderbolt driver fixes for reported issues
   - other small USB fixes
 
 All of these, except for the driver core fix, have been in linux-next
 with no reported problems.  The driver core fix was tested and verified
 to solve the issue by syzbot and the original reporter.

ddaf098ea7 driver core: class: properly reference count class_dev_iter()
When class_dev_iter is initialized, the reference count for the subsys
private structure is incremented, but never decremented, causing a
memory leak over time.  To resolve this, save off a pointer to the
internal structure into the class_dev_iter structure and then when the
iterator is finished, drop the reference count.

2e9f8ab68f mdio_bus: unhide mdio_bus_init prototype
mdio_bus_init() is either used as a local module_init() entry,
or it gets called in phy_device.c. In the former case, there
is no declaration, which causes a warning:

drivers/net/phy/mdio_bus.c:1371:12: error: no previous prototype for 'mdio_bus_init' [-Werror=missing-prototypes]

Remove the #ifdef around the declaration to avoid the warning..

26e239b37e mm: shrinkers: fix race condition on debugfs cleanup
When something registers and unregisters many shrinkers, such as:
    for x in $(seq 10000); do unshare -Ui true; done

Sometimes the following error is printed to the kernel log:
    debugfs: Directory '...' with parent 'shrinker' already present!

This occurs since commit badc28d492 ("mm: shrinkers: fix deadlock in
shrinker debugfs") / v6.2: Since the call to `debugfs_remove_recursive`
was moved outside the `shrinker_rwsem`/`shrinker_mutex` lock, but the call
to `ida_free` stayed inside, a newly registered shrinker can be
re-assigned that ID and attempt to create the debugfs directory before the
directory from the previous shrinker has been removed.

The locking changes in commit f95bdb700b ("mm: vmscan: make global slab
shrink lockless") made the race condition more likely, though it existed
before then.

Commit badc28d492 ("mm: shrinkers: fix deadlock in shrinker debugfs")
could be reverted since the issue is addressed should no longer occur
since the count and scan operations are lockless since commit 20cd1892fc
("mm: shrinkers: make count and scan in shrinker debugfs lockless"). 
However, since this is a contended lock, prefer instead moving `ida_free`
outside the lock to avoid the race.

a18ef64fe1 tracing: make ftrace_likely_update() declaration visible
This function is only used when CONFIG_TRACE_BRANCH_PROFILING is set and
DISABLE_BRANCH_PROFILING is not set, and the declaration is hidden
behind this combination of tests.

But that causes a warning when building with CONFIG_TRACING_BRANCHES,
since that sets DISABLE_BRANCH_PROFILING for the tracing code, and the
declaration is thus hidden:

  kernel/trace/trace_branch.c:205:6: error: no previous prototype for 'ftrace_likely_update' [-Werror=missing-prototypes]

Move the declaration out of the #ifdef to avoid the warning.

948f072ada SUNRPC: always free ctxt when freeing deferred request
Since the ->xprt_ctxt pointer was added to svc_deferred_req, it has not
been sufficient to use kfree() to free a deferred request.  We may need
to free the ctxt as well.

As freeing the ctxt is all that ->xpo_release_rqst() does, we repurpose
it to explicit do that even when the ctxt is not stored in an rqst.
So we now have ->xpo_release_ctxt() which is given an xprt and a ctxt,
which may have been taken either from an rqst or from a dreq.  The
caller is now responsible for clearing that pointer after the call to
->xpo_release_ctxt.

We also clear dr->xprt_ctxt when the ctxt is moved into a new rqst when
revisiting a deferred request.  This ensures there is only one pointer
to the ctxt, so the risk of double freeing in future is reduced.  The
new code in svc_xprt_release which releases both the ctxt and any
rq_deferred depends on this.

627bb528b0 media: dvb-core: Fix use-after-free due to race at dvb_register_device()
dvb_register_device() dynamically allocates fops with kmemdup()
to set the fops->owner.
And these fops are registered in 'file->f_ops' using replace_fops()
in the dvb_device_open() process, and kfree()d in dvb_free_device().

However, it is not common to use dynamically allocated fops instead
of 'static const' fops as an argument of replace_fops(),
and UAF may occur.
These UAFs can occur on any dvb type using dvb_register_device(),
such as dvb_dvr, dvb_demux, dvb_frontend, dvb_net, etc.

So, instead of kfree() the fops dynamically allocated in
dvb_register_device() in dvb_free_device() called during the
.disconnect() process, kfree() it collectively in exit_dvbdev()
called when the dvbdev.c module is removed.

4172385b0c media: dvb-core: Fix use-after-free due on race condition at dvb_net
A race condition may occur between the .disconnect function, which
is called when the device is disconnected, and the dvb_device_open()
function, which is called when the device node is open()ed.
This results in several types of UAFs.

The root cause of this is that you use the dvb_device_open() function,
which does not implement a conditional statement
that checks 'dvbnet->exit'.

So, add 'remove_mutex` to protect 'dvbnet->exit' and use
locked_dvb_net_open() function to check 'dvbnet->exit'.

6769a0b7ee media: dvb-core: Fix use-after-free on race condition at dvb_frontend
If the device node of dvb_frontend is open() and the device is
disconnected, many kinds of UAFs may occur when calling close()
on the device node.

The root cause of this is that wake_up() for dvbdev->wait_queue
is implemented in the dvb_frontend_release() function, but
wait_event() is not implemented in the dvb_frontend_stop() function.

So, implement wait_event() function in dvb_frontend_stop() and
add 'remove_mutex' which prevents race condition for 'fe->exit'.

4063384ef7 net: add vlan_get_protocol_and_depth() helper
Before blamed commit, pskb_may_pull() was used instead
of skb_header_pointer() in __vlan_get_protocol() and friends.

Few callers depended on skb->head being populated with MAC header,
syzbot caught one of them (skb_mac_gso_segment())

Add vlan_get_protocol_and_depth() to make the intent clearer
and use it where sensible.

This is a more generic fix than commit e9d3f80935
("net/af_packet: make sure to pull mac header") which was
dealing with a similar issue.

9949e2efb5 bonding: fix send_peer_notif overflow
Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3c
("bonding: add an option to specify a delay between peer notifications").
the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.

  ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000

To fix the overflow, let's set the send_peer_notif to u32 and limit
peer_notif_delay to 300s.

Fix it by just making io_uring_sqe_cmd() generally available - the types
are known, and there's no reason to hide it under CONFIG_IO_URING.

162bd18eb5 linux/dim: Do nothing if no time delta between samples
Add return value for dim_calc_stats. This is an indication for the
caller if curr_stats was assigned by the function. Avoid using
curr_stats uninitialized over {rdma/net}_dim, when no time delta between
samples. Coverity reported this potential use of an uninitialized
variable.

23a5b8bb02 x86/amd_nb: Add PCI ID for family 19h model 78h
Commit

  310e782a99 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")

switched to using amd_smn_read() which relies upon the misc PCI ID used
by DF function 3 being included in a table.  The ID for model 78h is
missing in that table, so amd_smn_read() doesn't work.

Add the missing ID into amd_nb, restoring s2idle on this system.

  [ bp: Simplify commit message. ]

e919a3f705 Minor tracing updates:
- Make buffer_percent read/write. The buffer_percent file is how users can
   state how long to block on the tracing buffer depending on how much
   is in the buffer. When it hits the "buffer_percent" it will wake the
   task waiting on the buffer. For some reason it was set to read-only.
   This was not noticed because testing was done as root without SELinux,
   but with SELinux it will prevent even root to write to it without having
   CAP_DAC_OVERRIDE.
 
 - The "touched_functions" was added this merge window, but one of the
   reasons for adding it was not implemented. That was to show what functions
   were not only touched, but had either a direct trampoline attached to
   it, or a kprobe or live kernel patching that can "hijack" the function
   to run a different function. The point is to know if there's functions
   in the kernel that may not be behaving as the kernel code shows. This can
   be used for debugging. TODO: Add this information to kernel oops too.

   reasons for adding it was not implemented.

   That was to show what functions were not only touched, but had either
   a direct trampoline attached to it, or a kprobe or live kernel
   patching that can "hijack" the function to run a different function.
   The point is to know if there's functions in the kernel that may not
   be behaving as the kernel code shows. This can be used for debugging.

   TODO: Add this information to kernel oops too.

6ce2c04fcb ftrace: Add MODIFIED flag to show if IPMODIFY or direct was attached
If a function had ever had IPMODIFY or DIRECT attached to it, where this
is how live kernel patching and BPF overrides work, mark them and display
an "M" in the enabled_functions and touched_functions files. This can be
used for debugging. If a function had been modified and later there's a bug
in the code related to that function, this can be used to know if the cause
is possibly from a live kernel patch or a BPF program that changed the
behavior of the code.

Also update the documentation on the enabled_functions and
touched_functions output, as it was missing direct callers and CALL_OPS.
And include this new modify attribute.

8e15605be8 9p patches for 6.4 merge window
This pull request includes a number of patches that didn't quite make
 the cut last merge window while we addressed some outstanding issues
 and review comments.  It includes some new caching modes for those that
 only want readahead caches and reworks how we do writeback caching so we
 are not keeping extra references around which both causes performance problems
 and uses lots of additional resources on the server.
 
 It also includes a new flag to force disabling of xattrs which can also
 cause major performance issues, particularly if the underlying filesystem
 on the server doesn't support them.
 
 Finally it adds a couple of additional mount options to better support
 directio and enabling caches when the server doesn't support qid.version.
 
 There was one late-breaking bug report that has also been included as its
 own patch where I forgot to propagate an embarassing bit-logic fix to the
 various variations of open.  Since that was only added to for-next a week
 ago, if you would like to not include it, I can include it in the first
 round of fixes for -rc2.
