The order in which 'users' counter is decremented vs calling drivers'
close() method is implementation specific, and we should not rely on
it. Let's introduce driver private flag and use it to signal ISR

The original intent of 84d3f6b76447 was to delay evaluating lid state until
all drivers have been loaded, with input device being opened from userspace
serving as a signal for this condition. Let's ensure that state updates
happen even if userspace closed (or in the future inhibited) input device.

When TPM 2.0 trusted keys code was moved to the trusted keys subsystem,
the operations were unwrapped from tpm_try_get_ops() and tpm_put_ops(),
which are used to take temporarily the ownership of the TPM chip. The
ownership is only taken inside tpm_send(), but this is not sufficient,
as in the key
Consider the following transcript:
$ keyctl add trusted kmk "new 32 blobauth=helloworld keyhandle=8000
migratable=1" @u
add_key: Invalid argument
The documentation has the following description:
migratable= 0|1 indicating permission to reseal to new PCR values,
default 1
When tpm_get_random() was introduced, it defined the following API for the
return value:
1. A positive value tells how many bytes of random data was generated.
2. A negative value on error.
However, in the call sites the API was used incorrectly, i.e. as it would
only return negative values and o

Recently, we have observed some janky issues caused by unpleasantly long
contention on mmap_lock which is held by smaps_rollup when probing large
processes. To address the problem, we let smaps_rollup detect if anyone
wants to acquire mmap_lock for write attempts. If yes, just release the
lock temp
Extend smap_gather_stats to support indicated beginning address at
which it should start gathering. To achieve the goal, we add a new
parameter @start assigned by the caller and try to refactor it for
simplicity.
If @start is 0, it will use the range of @vma for gathering.
Change since v2:
- This
Add new API to query if someone wants to acquire mmap_lock
for write attempts.
Using this instead of rwsem_is_contended makes it more tolerant
of future changes to the lock type.

smaps_rollup will try to grab mmap_lock and go through the whole vma
list until it finishes the iterating. When encountering large processes,
the mmap_lock will be held for a longer time, which may block other
write requests like mmap and munmap from progressing smoothly.
There are upcoming mmap_l

During testing, I see it is possible that rcu_pending() returns 1 when
offloaded callbacks are ready to execute thus raising the RCU softirq.
However, softirq does not execute offloaded callbacks. They are executed in a
kthread which is awakened independent of the softirq.
This commit therefore a

Currently, init_listener() tries to prevent adding a filter with
SECCOMP_FILTER_FLAG_NEW_LISTENER if one of the existing filters already
has a listener. However, this check happens without holding any lock that
would prevent another thread from concurrently installing a new filter
