269cbcf7b7 usb: dwc2: drd: fix soft connect when gadget is unconfigured
When the gadget driver hasn't been (yet) configured, and the cable is
connected to a HOST, the SFTDISCON gets cleared unconditionally, so the
HOST tries to enumerate it.
At the host side, this can result in a stuck USB port or worse. When
getting lucky, some dmesg can be observed at the host side:
 new high-speed USB device number ...
 device descriptor read/64, error -110

Fix it in drd, by checking the enabled flag before calling
dwc2_hsotg_core_connect(). It will be called later, once configured,
by the normal flow:
- udc_bind_to_driver
 - usb_gadget_connect
   - dwc2_hsotg_pullup
     - dwc2_hsotg_core_connect

c853685d11 usb: core: Unregister device on component_add() failure
Commit 8c67d06f3f ("usb: Link the ports to the connectors they are
attached to") creates a link to the USB Type-C connector for every new
port that is added when possible. If component_add() fails,
usb_hub_create_port_device() prints a warning but does not unregister
the device and does not return errors to the callers.

Syzbot reported a "WARNING in component_del()".

Fix this issue in usb_hub_create_port_device by calling device_unregister()
and returning the errors from component_add().

57bc3d3ae8 net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixup
ax88179_rx_fixup() contains several out-of-bounds accesses that can be
triggered by a malicious (or defective) USB device, in particular:

 - The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds,
   causing OOB reads and (on big-endian systems) OOB endianness flips.
 - A packet can overlap the metadata array, causing a later OOB
   endianness flip to corrupt data used by a cloned SKB that has already
   been handed off into the network stack.
 - A packet SKB can be constructed whose tail is far beyond its end,
   causing out-of-bounds heap data to be considered part of the SKB's
   data.

I have tested that this can be used by a malicious USB device to send a
bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response
that contains random kernel heap data.
It's probably also possible to get OOB writes from this on a
little-endian system somehow - maybe by triggering skb_cow() via IP
options processing -, but I haven't tested that.

117b4e96c7 usb: dwc3: gadget: Prevent core from processing stale TRBs
With CPU re-ordering on write instructions, there might
be a chance that the HWO is set before the TRB is updated
with the new mapped buffer address.
And in the case where core is processing a list of TRBs
it is possible that it fetched the TRBs when the HWO is set
but before the buffer address is updated.
Prevent this by adding a memory barrier before the HWO
is updated to ensure that the core always process the
updated TRBs.

5432184107 usb: gadget: f_uac2: Define specific wTerminalType
Several users have reported that their Win10 does not enumerate UAC2
gadget with the existing wTerminalType set to
UAC_INPUT_TERMINAL_UNDEFINED/UAC_INPUT_TERMINAL_UNDEFINED, e.g.
https://github.com/raspberrypi/linux/issues/4587#issuecomment-926567213.
While the constant is officially defined by the USB terminal types
document, e.g. XMOS firmware for UAC2 (commonly used for Win10) defines
no undefined output terminal type in its usbaudio20.h header.

Therefore wTerminalType of EP-IN is set to
UAC_INPUT_TERMINAL_MICROPHONE and wTerminalType of EP-OUT to
UAC_OUTPUT_TERMINAL_SPEAKER for the UAC2 gadget.

292d2c82b1 usb: raw-gadget: fix handling of dual-direction-capable endpoints
Under dummy_hcd, every available endpoint is *either* IN or OUT capable.
But with some real hardware, there are endpoints that support both IN and
OUT. In particular, the PLX 2380 has four available endpoints that each
support both IN and OUT.

raw-gadget currently gets confused and thinks that any endpoint that is
usable as an IN endpoint can never be used as an OUT endpoint.

Fix it by looking at the direction in the configured endpoint descriptor
instead of looking at the hardware capabilities.

With this change, I can use the PLX 2380 with raw-gadget.

fa77ce201f USB: serial: ch341: add support for GW Instek USB2.0-Serial devices
Programmable lab power supplies made by GW Instek, such as the
GPP-2323, have a USB port exposing a serial port to control the device.

Stringing the supplied Windows driver, references to the ch341 chip are
found. Binding the existing ch341 driver to the VID/PID of the GPP-2323
("GW Instek USB2.0-Serial" as per the USB product name) works out of the
box, communication and control is now possible.

This patch should work with any GPP series power supply due to
similarities in the product line.

ebe2b1add1 usb: f_fs: Fix use-after-free for epfile
Consider a case where ffs_func_eps_disable is called from
ffs_func_disable as part of composition switch and at the
same time ffs_epfile_release get called from userspace.
ffs_epfile_release will free up the read buffer and call
ffs_data_closed which in turn destroys ffs->epfiles and
mark it as NULL. While this was happening the driver has
already initialized the local epfile in ffs_func_eps_disable
which is now freed and waiting to acquire the spinlock. Once
spinlock is acquired the driver proceeds with the stale value
of epfile and tries to free the already freed read buffer
causing use-after-free.

Following is the illustration of the race:

      CPU1                                  CPU2

   ffs_func_eps_disable
   epfiles (local copy)
					ffs_epfile_release
					ffs_data_closed
					if (last file closed)
					ffs_data_reset
					ffs_data_clear
					ffs_epfiles_destroy
spin_lock
dereference epfiles

Fix this races by taking epfiles local copy & assigning it under
spinlock and if epfiles(local) is null then update it in ffs->epfiles
then finally destroy it.
Extending the scope further from the race, protecting the ep related
structures, and concurrent accesses.

ddf4b773aa ocfs2: fix a deadlock when commit trans
commit 6f1b228529 introduces a regression which can deadlock as
follows:

  Task1:                              Task2:
  jbd2_journal_commit_transaction     ocfs2_test_bg_bit_allocatable
  spin_lock(&jh->b_state_lock)        jbd_lock_bh_journal_head
  __jbd2_journal_remove_checkpoint    spin_lock(&jh->b_state_lock)
  jbd2_journal_put_journal_head
  jbd_lock_bh_journal_head

Task1 and Task2 lock bh->b_state and jh->b_state_lock in different
order, which finally result in a deadlock.

So use jbd2_journal_[grab|put]_journal_head instead in
ocfs2_test_bg_bit_allocatable() to fix it.

Patch series "ocfs2: fix a deadlock case".

This fixes a deadlock case in ocfs2.  We firstly export jbd2 symbols
jbd2_journal_[grab|put]_journal_head as preparation and later use them
in ocfs2 insread of jbd_[lock|unlock]_bh_journal_head to fix the
deadlock.

This patch (of 2):

This exports symbols jbd2_journal_[grab|put]_journal_head, which will be
used outside modules, e.g.  ocfs2.

27fe73394a mm, kasan: use compare-exchange operation to set KASAN page tag
It has been reported that the tag setting operation on newly-allocated
pages can cause the page flags to be corrupted when performed
concurrently with other flag updates as a result of the use of
non-atomic operations.

Fix the problem by using a compare-exchange loop to update the tag.

09c6304e38 kasan: test: fix compatibility with FORTIFY_SOURCE
With CONFIG_FORTIFY_SOURCE enabled, string functions will also perform
dynamic checks using __builtin_object_size(ptr), which when failed will
panic the kernel.

Because the KASAN test deliberately performs out-of-bounds operations,
the kernel panics with FORTIFY_SOURCE, for example:

 | kernel BUG at lib/string_helpers.c:910!
 | invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI
 | CPU: 1 PID: 137 Comm: kunit_try_catch Tainted: G    B             5.16.0-rc3+ #3
 | Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014
 | RIP: 0010:fortify_panic+0x19/0x1b
 | ...
 | Call Trace:
 |  kmalloc_oob_in_memset.cold+0x16/0x16
 |  ...

Fix it by also hiding `ptr` from the optimizer, which will ensure that
__builtin_object_size() does not return a valid size, preventing
fortified string functions from panicking.

61e28cf054 memory-failure: fetch compound_head after pgmap_pfn_valid()
memory_failure_dev_pagemap() at the moment assumes base pages (e.g.
dax_lock_page()).  For devmap with compound pages fetch the
compound_head in case a tail page memory failure is being handled.

Currently this is a nop, but in the advent of compound pages in
dev_pagemap it allows memory_failure_dev_pagemap() to keep working.

Without this fix memory-failure handling (i.e.  MCEs on pmem) with
device-dax configured namespaces will regress (and crash).

e7f1e8834b binfmt_misc: fix crash when load/unload module
We should unregister the table upon module unload otherwise something
horrible will happen when we load binfmt_misc module again.  Also note
that we should keep value returned by register_sysctl_mount_point() and
release it later, otherwise it will leak.

Also, per Christian's comment, to fully restore the old behavior that
won't break userspace the check(binfmt_misc_header) should be
eliminated.

To reproduce:
  modprobe binfmt_misc
  modprobe -r binfmt_misc
  modprobe binfmt_misc
  modprobe -r binfmt_misc
  modprobe binfmt_misc

resulting in

  modprobe: can't load module binfmt_misc (kernel/fs/binfmt_misc.ko): Cannot allocate memory

and an unhappy kernel:

  binfmt_misc: Failed to create fs/binfmt_misc sysctl mount point
  binfmt_misc: Failed to create fs/binfmt_misc sysctl mount point
  BUG: unable to handle page fault for address: fffffbfff8004802
  Call Trace:
    init_misc_binfmt+0x2d/0x1000 [binfmt_misc]

e255759e5a Char/Misc driver fixes for 5.17-rc2
Here are two small char/misc driver fixes for 5.17-rc2 that fix some
 reported issues.  They include:
 	- fix up a merge issue in the at25.c driver that ended up
 	  dropping some lines in the driver.  The removed lines ended
 	  being needed, so this restores it and the driver works again.
 	- counter core fix where the wrong error was being returned,
 	  NULL should be the correct error for when memory is gone here,
 	  like the kmalloc() core does.
 
 Both of these have been in linux-next this week with no reported issues.

 	  This is being reworked and should show up in a later -rc1
 	  release, but it's not ready for 5.17
 	- rpmsg tty race fix
 	- restore the cyclades.h uapi header file.  Turns out a compiler
 	  test suite used it for some unknown reason.  Bring it back
 	  just for the parts that are used by the builder test so they
 	  continue to build.  No functionality is restored as no one
 	  actually has this hardware anymore, nor is it really tested.
 	- stm32 driver fixes
 	- n_gsm flow control fixes
 	- pl011 driver fix
 	- rs485 initialization fix
