fbdev: fbcon: Properly revert changes when vc_resize() failed

wait_on_bit: add an acquire memory barrier
There are several places in the kernel where wait_on_bit is not followed

On architectures with weak memory ordering, it may happen that memory

they may return invalid data.

crypto: lib - remove unneeded selection of XOR_BLOCKS
CRYPTO_LIB_CHACHA_GENERIC doesn't need to select XOR_BLOCKS. It perhaps
was thought that it's needed for __crypto_xor, but that's not the case.
Enabling XOR_BLOCKS is problematic because the XOR_BLOCKS code runs a

systems that didn't have it enabled before.

Bluetooth: hci_event: Fix vendor (unknown) opcode status handling
Commit c8992cffbe74 ("Bluetooth: hci_event: Use of a function table to
handle Command Complete") was (presumably) meant to only refactor things
without any functional changes.
But it does have one undesirable side-effect, before *status would always
be set to skb->data[0] and it might be overridden by some of the opcode
specific handling. While now it always set by the opcode specific handlers.
This means that if the opcode is not known *status does not get set any
more at all!
This behavior change has broken bluetooth support for BCM4343A0 HCIs,
the hci_bcm.c code tries to configure UART attached HCIs at a higher
baudraute using vendor specific opcodes. The BCM4343A0 does not
support this and this used to simply fail:
[ 25.646442] Bluetooth: hci0: BCM: failed to write clock (-56)
[ 25.646481] Bluetooth: hci0: Failed to set baudrate
After which things would continue with the initial baudraute. But now
that hci_cmd_complete_evt() no longer sets status for unknown opcodes
*status is left at 0. This causes the hci_bcm.c code to think the baudraute
has been changed on the HCI side and to also adjust the UART baudrate,
after which communication with the HCI is broken, leading to:
And non working bluetooth. Fix this by restoring the previous
default "*status = skb->data[0]" handling for unknown opcodes.

The problem here is that a range of tnum_range(0, map->max_entries - 1) has
limited ability to represent the concrete tight range with the tnum as the
set of resulting states from value + mask can result in a superset of the
actual intended range, and as such a tnum_in(range, reg->var_off) check may
yield true when it shouldn't, for example tnum_range(0, 2) would result in
00XX -> v = 0000, m = 0011 such that the intended set of {0, 1, 2} is here
represented by a less precise superset of {0, 1, 2, 3}. As the register is
known const scalar, really just use the concrete reg->var_off.value for the
upper index check.

audit_return_fixup() before the filters. This was causing syscall

net: lantiq_xrx200: fix errors under memory pressure
This series fixes issues that can occur in the driver under memory pressure.
Situations when the system cannot allocate memory are rare, so the mentioned
bugs have been fixed recently. The patches have been tested on a BT Home
router with the Lantiq xRX200 chipset.
Changelog:
v3: - removed netdev_err() log from the first patch

- the second patch has been changed, so that under memory pressure situation
the driver will not receive packets indefinitely regardless of the NAPI budget,
- the third patch has been added.

This is incorrect for two reasons:
* the function terminates without enabling interrupts or scheduling NAPI,
* the error code (-ENOMEM) is returned instead of the number of received
packets.
After the first memory allocation failure occurs, packet reception is
locked due to disabled interrupts from DMA..

Adding a delay between two writes to this register helps, but we can
also simply omit the offending second write. This patch uses the second
approach and is based on a suggestion from Qi Duan.
Benefit of this approach is that we can save few register writes, also

rxrpc: Fix locking in rxrpc's sendmsg
Fix three bugs in the rxrpc's sendmsg implementation:
(1) rxrpc_new_client_call() should release the socket lock when returning
an error from rxrpc_get_call_slot().
(2) rxrpc_wait_for_tx_window_intr() will return without the call mutex
held in the event that we're interrupted by a signal whilst waiting
for tx space on the socket or relocking the call mutex afterwards.
Fix this by: (a) moving the unlock/lock of the call mutex up to
rxrpc_send_data() such that the lock is not held around all of
rxrpc_wait_for_tx_window*() and (b) indicating to higher callers
whether we're return with the lock dropped. Note that this means
recvmsg() will not block on this call whilst we're waiting.
(3) After dropping and regaining the call mutex, rxrpc_send_data() needs
to go and recheck the state of the tx_pending buffer and the
tx_total_len check in case we raced with another sendmsg() on the same
call.
Thinking on this some more, it might make sense to have different locks for
sendmsg() and recvmsg(). There's probably no need to make recvmsg() wait
for sendmsg(). It does mean that recvmsg() can return MSG_EOR indicating
that a call is dead before a sendmsg() to that call returns - but that can
currently happen anyway.

Merge branch 'Fix incorrect pruning for ARG_CONST_ALLOC_SIZE_OR_ZERO'
Kumar Kartikeya Dwivedi says:
====================
A fix for a missing mark_chain_precision call that leads to eager pruning and
loading of invalid programs when the more permissive case is in the straight
line exploration. Please see the commit log for details, and selftest for an
example.
====================
selftests/bpf: Add regression test for pruning fix
Add a test to ensure we do mark_chain_precision for the argument type
ARG_CONST_ALLOC_SIZE_OR_ZERO. For other argument types, this was already
done, but propagation for missing for this case. Without the fix, this
test case loads successfully.
bpf: Do mark_chain_precision for ARG_CONST_ALLOC_SIZE_OR_ZERO
Precision markers need to be propagated whenever we have an ARG_CONST_*
style argument, as the verifier cannot consider imprecise scalars to be
equivalent for the purposes of states_equal check when such arguments
refine the return value (in this case, set mem_size for PTR_TO_MEM). The
resultant mem_size for the R0 is derived from the constant value, and if
the verifier incorrectly prunes states considering them equivalent where
such arguments exist (by seeing that both registers have reg->precise as
false in regsafe), we can end up with invalid programs passing the
verifier which can do access beyond what should have been the correct
mem_size in that explored state.
For the first case, the single line execution's exploration will prune
the search at insn 14 for the branch insn 9's second leg as it will be
verified first using r2 = -1 (UINT_MAX), while as w1 at insn 9 will
always be 0 so at runtime we don't get error for being greater than
UINT_MAX/4 from bpf_ringbuf_reserve. The verifier during regsafe just
sees reg->precise as false for both r2 registers in both states, hence
considers them equal for purposes of states_equal.
If we propagated precise markers using the backtracking support, we
would use the precise marking to then ensure that old r2 (UINT_MAX) was
within the new r2 (1) and this would never be true, so the verification
would rightfully fail.
The end result is that the out of bounds access at instruction 19 would
be permitted without this fix.
Note that reg->precise is always set to true when user does not have
CAP_BPF (or when subprog count is greater than 1 (i.e. use of any static
or global functions)), hence this is only a problem when precision marks
need to be explicitly propagated (i.e. privileged users with CAP_BPF).
A simplified test case has been included in the next patch to prevent
future regressions.

docs: Update version number from 5.x to 6.x in README.rst
A quick 'grep "5\.x" . -R' on Documentation shows that README.rst,
2.Process.rst and applying-patches.rst all mention the version number "5.x"
for kernel releases.
As the next release will be version 6.0, updating the version number to 6.x
in README.rst seems reasonable.
The description in 2.Process.rst is just a description of recent kernel
releases, it was last updated in the beginning of 2020, and can be
revisited at any time on a regular basis, independent of changing the
version number from 5 to 6. So, there is no need to update this document
now when transitioning from 5.x to 6.x numbering.
The document applying-patches.rst is probably obsolete for most users
anyway, a reader will sufficiently well understand the steps, even it
mentions version 5 rather than version 6. So, do not update that to a
version 6.x numbering scheme.
Update version number from 5.x to 6.x in README.rst only.

xen/privcmd: fix error exit of privcmd_ioctl_dm_op()
The error exit of privcmd_ioctl_dm_op() is calling unlock_pages()
potentially with pages being NULL, leading to a NULL dereference.
Additionally lock_pages() doesn't check for pin_user_pages_fast()
having been completely successful, resulting in potentially not
locking all pages into memory. This could result in sporadic failures
when using the related memory in user mode.
Fix all of that by calling unlock_pages() always with the real number
of pinned pages, which will be zero in case pages being NULL, and by
checking the number of pages pinned by pin_user_pages_fast() matching
the expected number of pages.

io_uring/net: save address for sendzc async execution
We usually copy all bits that a request needs from the userspace for

s390/mm: do not trigger write fault when vma does not allow VM_WRITE
For non-protection pXd_none() page faults in do_dat_exception(), we
call do_exception() with access == (VM_READ | VM_WRITE | VM_EXEC).
In do_exception(), vma->vm_flags is checked against that before
calling handle_mm_fault().
Since commit 92f842eac7ee3 ("[S390] store indication fault optimization"),
we call handle_mm_fault() with FAULT_FLAG_WRITE, when recognizing that
it was a write access. However, the vma flags check is still only
checking against (VM_READ | VM_WRITE | VM_EXEC), and therefore also

does not allow VM_WRITE.
Fix this by changing access check in do_exception() to VM_WRITE only,

s390: fix double free of GS and RI CBs on fork() failure
The pointers for guarded storage and runtime instrumentation control
blocks are stored in the thread_struct of the associated task. These
pointers are initially copied on fork() via arch_dup_task_struct()
and then cleared via copy_thread() before fork() returns. If fork()
happens to fail after the initial task dup and before copy_thread(),
the newly allocated task and associated thread_struct memory are
freed via free_task() -> arch_release_task_struct(). This results in
a double free of the guarded storage and runtime info structs
because the fields in the failed task still refer to memory
associated with the source task.
This problem can manifest as a BUG_ON() in set_freepointer() (with
CONFIG_SLAB_FREELIST_HARDENED enabled) or KASAN splat (if enabled)
when running trinity syscall fuzz tests on s390x. To avoid this
problem, clear the associated pointer fields in
arch_dup_task_struct() immediately after the new task is copied.
Note that the RI flag is still cleared in copy_thread() because it
resides in thread stack memory and that is where stack info is
copied.

HID: AMD_SFH: Add a DMI quirk entry for Chromebooks
Google Chromebooks use Chrome OS Embedded Controller Sensor Hub instead

functionalities, even including the registers necessary for feature
detections.
The behavior was observed with Lenovo ThinkPad C13 Yoga.
There is a timing issue captured during ishtp client sending stress tests.
It was observed during stress tests that ISH firmware is getting out of
ordered messages. This is a rare scenario as the current set of ISH client
drivers don't send much data to firmware. But this may not be the case
going forward.
When message size is bigger than IPC MTU, ishtp splits the message into
fragments and uses serialized async method to send message fragments.
The call stack:
ishtp_cl_send_msg_ipc->ipc_tx_callback(first fregment)->
ishtp_send_msg(with callback)->write_ipc_to_queue->
write_ipc_from_queue->callback->ipc_tx_callback(next fregment)......
When an ipc write complete interrupt is received, driver also calls
write_ipc_from_queue->ipc_tx_callback in ISR to start sending of next fragment.
Through ipc_tx_callback uses spin_lock to protect message splitting, as the
serialized sending method will call back to ipc_tx_callback again, so it doesn't
put sending under spin_lock, it causes driver cannot guarantee all fragments
be sent in order.
Considering this scenario:
ipc_tx_callback just finished a fragment splitting, and not call ishtp_send_msg
yet, there is a write complete interrupt happens, then ISR->write_ipc_from_queue
->ipc_tx_callback->ishtp_send_msg->write_ipc_to_queue......
Because ISR has higher exec priority than normal thread, this causes the new
fragment be sent out before previous fragment. This disordered message causes
invalid message to firmware.
The solution is, to send fragments synchronously:
Use ishtp_write_message writing fragments into tx queue directly one by one,
instead of ishtp_send_msg only writing one fragment with completion callback.
As no completion callback be used, so change ipc_tx_callback to ipc_tx_send.
