Currently, the sched code checks if the rq clock has been
updated after its lock has been held when CONFIG_SCHED_DEBUG
is enabled. It tracks this by clearing the RQCF_UPDATED bit
when a lock is acquired and setting it upon a subsequent
update_rq_clock() call. It warns if rq clock is read without
RQCF_UPDATED flag indicating the code path missed updating
the clock.
When migrate_tasks() is called during a pause_cpus() event,
the local variable orf is updated with the contents of *rf,
prior to the call to update_rq_clock(). As a result, when
migrate_tasks() restores *rf from the local variable the
RQCF_UPDATED flag is lost. This clearing out of the
RQCF_UPDATED flag leads to a warning when the next task
is being pushed out.
For example in migrate_tasks()
orf = rf; // save flags, RQCF_UPDATE cleared
update_rq_clock() // set RQCF_UPDATE
for()
...
__migrate_task(dead_rq, new_cpu)
...
--> if migration, restore dead_rq's flags with orf.
--> We loose RQCF_UPDATE
rq_relock(dead_rq, orf)
This leaves the current cpu's rq clock_update_flags with the
RQCF_UPDATED flag cleared, an error condition with
CONFIG_SCHED_DEBUG enabled.
Fix the issue for by ensuring that the local variable orf
has the RQCF_UPDATED flag set, allowing the current
CPU's rq to have the flag set and leaving it in a good state
for future usage.
pause_cpus() is currently Android specific. As cpu_pause does
not rely on stop_machine_cpuslocked() like the regular
hotunplug path does, there's a risk for another CPU to
read the rq_clock, after we cleared RQCF_UPDATE, when using
pause_cpus(). This change will have little or no impact outside
of Android currently. If pause_cpus() or drain_rq_cpu_stop()
are merged upstream this change should be merged as well.

The broadcast device is switched to oneshot mode when the system switches
to oneshot mode. If a broadcast clock event device is registered after the
system switched to oneshot mode, it will stay in periodic mode forever.
Ensure that a late registered device which is selected as broadcast device
is initialized in oneshot mode when the system already uses oneshot mode.

[ Upstream commit 24c109bb15 ]
The mixed signed bounds check really belongs into retrieve_ptr_limit()
instead of outside of it in adjust_ptr_min_max_vals(). The reason is
that this check is not tied to PTR_TO_MAP_VALUE only, but to all pointer
types that we handle in retrieve_ptr_limit() and given errors from the latter
propagate back to adjust_ptr_min_max_vals() and lead to rejection of the
program, it's a better place to reside to avoid anything slipping through
for future types. The reason why we must reject such off_reg is that we
otherwise would not be able to derive a mask, see details in 9d7eceede7
("bpf: restrict unknown scalars of mixed signed bounds for unprivileged").

commit 6d48b7912c upstream.
Clang doesn't like format strings that truncate a 32-bit
value to something shorter:
kernel/locking/lockdep.c:709:4: error: format specifies type 'short' but the argument has type 'int' [-Werror,-Wformat]
In this case, the warning is a slightly questionable, as it could realize
that both class->wait_type_outer and class->wait_type_inner are in fact
8-bit struct members, even though the result of the ?: operator becomes an
'int'.
However, there is really no point in printing the number as a 16-bit
'short' rather than either an 8-bit or 32-bit number, so just change
it to a normal %d.

commit 06ab134ce8 upstream.
On x86 the struct pt_regs * grabbed by task_pt_regs() points to an
offset of task->stack. The pt_regs are later dereferenced in
__bpf_get_stack (e.g. by user_mode() check). This can cause a fault if
the task in question exits while bpf_get_task_stack is executing, as
warned by task_stack_page's comment:
* When accessing the stack of a non-current task that might exit, use
* try_get_task_stack() instead. task_stack_page will return a pointer
* that could get freed out from under you.
Taking the comment's advice and using try_get_task_stack() and
put_task_stack() to hold task->stack refcount, or bail early if it's
already 0. Incrementing stack_refcount will ensure the task's stack
sticks around while we're using its data.
I noticed this bug while testing a bpf task iter similar to
bpf_iter_task_stack in selftests, except mine grabbed user stack, and
getting intermittent crashes, which resulted in dumps like:

commit 25fc94b2f0 upstream.
Invoking BPF_OBJ_GET on a pinned bpf_link checks the path access
permissions based on file_flags, but the returned fd ignores flags.
This means that any user can acquire a "read-write" fd for a pinned
link with mode 0664 by invoking BPF_OBJ_GET with BPF_F_RDONLY in
file_flags. The fd can be used to invoke BPF_LINK_DETACH, etc.
Fix this by refusing non-O_RDWR flags in BPF_OBJ_GET. This works
because OBJ_GET by default returns a read write mapping and libbpf
doesn't expose a way to override this behaviour for programs
and links.

commit 12aa8a9467 upstream.
With the introduction of the struct_ops program type, it became possible to
implement kernel functionality in BPF, making it viable to use BPF in place
of a regular kernel module for these particular operations.
Thus far, the only user of this mechanism is for implementing TCP
congestion control algorithms. These are clearly marked as GPL-only when
implemented as modules (as seen by the use of EXPORT_SYMBOL_GPL for
tcp_register_congestion_control()), so it seems like an oversight that this
was not carried over to BPF implementations. Since this is the only user
of the struct_ops mechanism, just enforcing GPL-only for the struct_ops
program type seems like the simplest way to fix this.

1 <func>: checksum mismatch, \
(<lineno chksum A>, <cfg chksum B>) != (<lineno chksum A>, <cfg chksum C>)
2 Invalid .gcda File!
...
Fix up the function signatures so calling this function interprets its
parameters correctly and computes the correct cfg checksum. In
particular, in clang-11, the additional checksum is no longer optional.

commit 9deb193af6 upstream.
Commit cbc3b92ce0 fixed an issue to modify the macros of the stack trace
event so that user space could parse it properly. Originally the stack
trace format to user space showed that the called stack was a dynamic
array. But it is not actually a dynamic array, in the way that other
dynamic event arrays worked, and this broke user space parsing for it. The
update was to make the array look to have 8 entries in it. Helper
functions were added to make it parse it correctly, as the stack was
dynamic, but was determined by the size of the event stored.
Although this fixed user space on how it read the event, it changed the
internal structure used for the stack trace event. It changed the array
size from [0] to [8] (added 8 entries). This increased the size of the
stack trace event by 8 words. The size reserved on the ring buffer was the
size of the stack trace event plus the number of stack entries found in
the stack trace. That commit caused the amount to be 8 more than what was
needed because it did not expect the caller field to have any size. This
produced 8 entries of garbage (and reading random data) from the stack
trace event:
<idle>-0 [002] d... 1976396.837549: <stack trace>
=> trace_event_raw_event_sched_switch
=> __traceiter_sched_switch
=> __schedule
=> schedule_idle
=> do_idle
=> cpu_startup_entry
=> secondary_startup_64_no_verify
=> 0xc8c5e150ffff93de
=> 0xffff93de
=> 0
=> 0
=> 0xc8c5e17800000000
=> 0x1f30affff93de
=> 0x00000004
=> 0x200000000
Instead, subtract the size of the caller field from the size of the event
to make sure that only the amount needed to store the stack trace is
reserved.

The intent is to avoid writing init code after init (because the text
might have been freed). The code is needlessly different between
jump_label and static_call and not obviously correct.
The existing code relies on the fact that the module loader clears the
init layout, such that within_module_init() always fails, while
jump_label relies on the module state which is more obvious and
matches the kernel logic.

The fexit/fmod_ret programs can be attached to kernel functions that can sleep.
The synchronize_rcu_tasks() will not wait for such tasks to complete.
In such case the trampoline image will be freed and when the task
wakes up the return IP will point to freed memory causing the crash.
Solve this by adding percpu_ref_get/put for the duration of trampoline
and separate trampoline vs its image life times.
The "half page" optimization has to be removed, since
first_half->second_half->first_half transition cannot be guaranteed to
complete in deterministic time. Every trampoline update becomes a new image.
The image with fmod_ret or fexit progs will be freed via percpu_ref_kill and
call_rcu_tasks. Together they will wait for the original function and
trampoline asm to complete. The trampoline is patched from nop to jmp to skip
fexit progs. They are freed independently from the trampoline. The image with
fentry progs only will be freed via call_rcu_tasks_trace+call_rcu_tasks which
will wait for both sleepable and non-sleepable progs to complete.

android_rvh_replace_next_task_fair() hooks allows vendor modules to
replace the next task selected by the CFS. There are two cases in
how this hook is called.
1. When the previous task is also a CFS task. In this case, the
task_struct (p) and sched_entity (se) arguments passed to this
hook are valid and point to the task selected by the CFS.
2. When the previous task is not a CFS task. In this case, the
arguments passed to this hook are not initialized.
Initialize these arguments to NULL which allows vendor modules
when not to peek into the selected task by CFS.

This patch creates a config that can be used to disable the automount of
tracefs in the debugfs filesystem. Since the automount happens everytime
the path /sys/kernel/debug/tracing is accessed, unmounting from
userspace is ineffective against it.
The config is intended to prevent new tracefs clients from depending on
the automounted tracefs instance mounted at /sys/kernel/debug/tracing
instead of the one at /sys/kernel/tracing. Since Android R launching
devices and newer cannot mount debugfs in production builds, the
config is intended to minimize the difference between user and
userdebug builds w.r.t to tracefs and prevent regresssions.

A vendor hook is added in post_init_entity_util_avg before
a new cfs task's util is attached to cfs_rq's util so that
vendors can gather and modify se's information to modify
scheduling behavior and DVFS as they want.
trace_android_rvh_new_task_stats is not a proper hook because
it is called after the task's util is attached to cfs_rq's util,
which means updating cfs_rq's sched_avg and DVFS request are done.

Allow up to two attachments to restricted vendor hooks to enable OEM
and vendor coexistence.
Priorities are not exposed to callers on purpose. Life's too short to
re-order the callback array with concurrent readers.
