vmci_ctx_get_chkpt_doorbells()
A kernel-infoleak was reported by syzbot, which was caused because
dbells was left uninitialized.
Using kzalloc() instead of kmalloc() fixes this issue.

The usage of in_interrupt() in xpc_partition_disengaged() is clearly
intended to avoid canceling the timeout timer when the function is invoked
from the timer callback.
While in_interrupt() is deprecated and ill defined as it does not provide
what the name suggests it catches the intended case.
Add an argument to xpc_partition_disengaged() which is true if called
from timer and otherwise false.
Use del_timer_sync() instead of del_singleshot_timer_sync() which is the
same thing.
Note: This does not prevent reentrancy into the function as the function
has no concurrency control and timer callback and regular task context
callers can happen concurrently on different CPUs or the timer can
interrupt the task context before it is able to cancel it.
While the only driver which is providing the arch_xpc_ops callbacks
(xpc_uv) seems not to have a reentrancy problem and the only negative
effect would be a double dev_info() entry in dmesg, the whole mechanism is
conceptually broken.
But that's not subject of this cleanup endeavour and left as an exercise to
the folks who might have interest to make that code fully correct.
[bigeasy: Add the argument, use del_timer_sync().]

When building with KASAN and LKDTM, clang may implictly generate an
asan.module_ctor function in the LKDTM rodata object. The Makefile moves
the lkdtm_rodata_do_nothing() function into .rodata by renaming the
file's .text section to .rodata, and consequently also moves the ctor
function into .rodata, leading to a boot time crash (splat below) when
the ctor is invoked by do_ctors().
Let's prevent this by marking the function as noinstr rather than
notrace, and renaming the file's .noinstr.text to .rodata. Marking the
function as noinstr will prevent tracing and kprobes, and will inhibit
any undesireable compiler instrumentation.
The ctor function (if any) will be placed in .text and will work
correctly.
Example splat before this patch is applied:

The ETM device can't keep up with the core pipeline when cpu core
is at full speed. This may cause overflow within core and its ETM.
This is a common phenomenon on ETM devices.
On HiSilicon Hip08 platform, a specific feature is added to set
core pipeline. So commit rate can be reduced manually to avoid ETM
overflow.

When the ETR is used in perf mode with a larger buffer (configured
via sysfs or the default size of 1M) than the perf aux buffer size,
we end up inserting the barrier packet at the wrong offset, while
moving the offset forward. i.e, instead of the "new moved offset",
we insert it at the current hardware buffer offset. These packets
will not be visible as they are never copied and could lead to
corruption in the trace decoding side, as the decoder is not aware
that it needs to reset the decoding.

Currently there is a null pointer check for hdmi_phy that implies it
may be null, however a dev_err messages dereferences this potential null
pointer. Avoid a null pointer dereference by only emitting the dev_err
message if hdmi_phy is non-null. It is a moot point if the error message
needs to be printed at all, but since this is a relatively new piece of
code it may be useful to keep the message in for the moment in case there
are unforseen errors that need to be reported.

intel_idle: Build fix
|
|
This reverts commit d162219c655c8cf8003128a13840d6c1e183fb80.
The device uses a VIRTIO device ID out of a not-for-production range.
Releasing Linux using an ID out of this range will make it conflict with
development setups. An official request to reserve an ID for an MEI
device is yet to be submitted to the virtio TC, thus there's no chance
it will be reserved and fixed in time before the next release.
Once requested it usually takes 2-3 weeks to land in the spec, which
means the device can be supported with the official ID in the next Linux
version if contributors act quickly.

Commit 882ec4e609c1 ("dm table: stack 'chunk_sectors' limit to account
for target-specific splitting") caused a couple regressions:
1) Using lcm_not_zero() when stacking chunk_sectors was a bug because
chunk_sectors must reflect the most limited of all devices in the
IO stack.
2) DM targets that set max_io_len but that do _not_ provide an
.iterate_devices method no longer had there IO split properly.
And commit 5091cdec56fa ("dm: change max_io_len() to use
blk_max_size_offset()") also caused a regression where DM no longer
supported varied (per target) IO splitting. The implication being the
potential for severely reduced performance for IO stacks that use a DM
target like dm-cache to hide performance limitations of a slower
device (e.g. one that requires 4K IO splitting).
Coming full circle: Fix all these issues by discontinuing stacking
chunk_sectors up using ti->max_io_len in dm_calculate_queue_limits(),
add optional chunk_sectors override argument to blk_max_size_offset()
and update DM's max_io_len() to pass ti->max_io_len to its
blk_max_size_offset() call.
Passing in an optional chunk_sectors override to blk_max_size_offset()
allows for code reuse of block's centralized calculation for max IO
size based on provided offset and split boundary.

Currently, locking of ->session is very inconsistent; most places
protect it using the legacy tty mutex, but disassociate_ctty(),
__do_SAK(), tiocspgrp() and tiocgsid() don't.
Two of the writers hold the ctrl_lock (because they already need it for
->pgrp), but __proc_set_tty() doesn't do that yet.
On a PREEMPT=y system, an unprivileged user can theoretically abuse
this broken locking to read 4 bytes of freed memory via TIOCGSID if
tiocgsid() is preempted long enough at the right point. (Other things
might also go wrong, especially if root-only ioctls are involved; I'm
not sure about that.)
Change the locking on ->session such that:
- tty_lock() is held by all writers: By making disassociate_ctty()
hold it. This should be fine because the same lock can already be
taken through the call to tty_vhangup_session().
The tricky part is that we need to shorten the area covered by
siglock to be able to take tty_lock() without ugly retry logic; as
far as I can tell, this should be fine, since nothing in the
signal_struct is touched in the `if (tty)` branch.
- ctrl_lock is held by all writers: By changing __proc_set_tty() to
hold the lock a little longer.
- All readers that aren't holding tty_lock() hold ctrl_lock: By
adding locking to tiocgsid() and __do_SAK(), and expanding the area
covered by ctrl_lock in tiocspgrp().

tiocspgrp() takes two tty_struct pointers: One to the tty that userspace
passed to ioctl() (`tty`) and one to the TTY being changed (`real_tty`).
These pointers are different when ioctl() is called with a master fd.
To properly lock real_tty->pgrp, we must take real_tty->ctrl_lock.
This bug makes it possible for racing ioctl(TIOCSPGRP, ...) calls on
both sides of a PTY pair to corrupt the refcount of `struct pid`,
leading to use-after-free errors.

Manivannan writes:
MHI patches for v5.11
Here is the MHI patch set for v5.11. Most of the patches are cleanups and fixes
but there are some noticeable changes too:
1. Loic finally removed the auto-start option from the channel parameters of the
MHI controller. It is the duty of the client drivers like qrtr to start/stop the
channels when required, so we decided to remove this option. As a side effect,
we changed the qrtr driver to start the channels during its probe and removed
the auto-start option from ath11k controller.
**NOTE** Since these changes spawns both MHI and networking trees, the patches
are maintained in an immutable branch [1] and pulled into both mhi-next and
ath11k-next branches. The networking patches got acks from ath11k and networking
maintainers as well.
2. Loic added a generic MHI pci controller driver. This driver will be used by
the PCI based Qualcomm modems like SDX55 and exposes channels such as QMI,
IP_HW0, IPCR etc...
3. Loic fixed the MHI device hierarchy by maintaining the correct parent child
relationships. Earlier all MHI devices lived in the same level under the parent
device like PCIe. But now, the MHI devices belonging to channels will become the
children of controller MHI device.
4. Finally Loic also improved the MHI device naming by using indexed names such
as mhi0, mhi1, etc... This will break the userspace applications depending on
the old naming convention but since the only one user so far is Jeff Hugo's AI
accelerator apps, we decided to make this change now itself with his agreement.
5. Bhaumik fixed the qrtr driver by stopping the channels during remove. This
patch also got ack from networking maintainer and we decided to take it through
MHI tree (via immutable branch) since we already had a qrtr change.
