ANDROID: sched: cpufreq_schedutil: add sugov tracepoints
Add vendor hook tracepoints to track when cpu util gets updated and when freq is choosen.

ANDROID: mm: oom_kill: reap memory of a task that receives SIGKILL
Free the pages parallely for a task that receives SIGKILL, from ULMK process, using the oom_reaper. This freeing of pages will help to give the pages to buddy system well advance. Add the boot param, reap_mem_when_killed_by=, that configures the process name, the kill signal to a process from which makes its memory reaped by oom reaper. As an example, when reap_mem_when_killed_by=lmkd, then all the processes that receives the kill signal from lmkd is added to oom reaper. Not initializing this param makes this feature disabled.

ANDROID: rwsem: Export rwsem_waiter struct for loadable modules
The rwsem_waiter struct is needed in vendor hook alter_rwsem_list_add. It has parameter sem which is a struct rw_semaphore (already export in rwsem.h), inside the structure there is a wait_list to link "struct rwsem_waiter" items. The task information in each item of the wait_list is needed to be referenced in vendor loadable modules. Bug: 174902706 Signed-off-by: Huang Yiwei <hyiwei@codeaurora.org> Change-Id: Ic7d21ffdd795eaa203989751d26f8b1f32134d8b |

UPSTREAM: seccomp: Remove bogus __user annotations
Buffers that are passed to read_actions_logged() and write_actions_logged() are in kernel memory; the sysctl core takes care of copying from/to userspace. Fixes: |

UPSTREAM: seccomp/cache: Add "emulator" to check if filter is constant allow
SECCOMP_CACHE will only operate on syscalls that do not access
any syscall arguments or instruction pointer. To facilitate
this we need a static analyser to know whether a filter will
return allow regardless of syscall arguments for a given
architecture number / syscall number pair. This is implemented
here with a pseudo-emulator, and stored in a per-filter bitmap.
In order to build this bitmap at filter attach time, each filter is
emulated for every syscall (under each possible architecture), and
checked for any accesses of struct seccomp_data that are not the "arch"
nor "nr" (syscall) members. If only "arch" and "nr" are examined, and
the program returns allow, then we can be sure that the filter must
return allow independent from syscall arguments.
Nearly all seccomp filters are built from these cBPF instructions:
BPF_LD | BPF_W | BPF_ABS
BPF_JMP | BPF_JEQ | BPF_K
BPF_JMP | BPF_JGE | BPF_K
BPF_JMP | BPF_JGT | BPF_K
BPF_JMP | BPF_JSET | BPF_K
BPF_JMP | BPF_JA
BPF_RET | BPF_K
BPF_ALU | BPF_AND | BPF_K
Each of these instructions are emulated. Any weirdness or loading
from a syscall argument will cause the emulator to bail.
The emulation is also halted if it reaches a return. In that case,
if it returns an SECCOMP_RET_ALLOW, the syscall is marked as good.
Emulator structure and comments are from Kees [1] and Jann [2].
Emulation is done at attach time. If a filter depends on more
filters, and if the dependee does not guarantee to allow the
syscall, then we skip the emulation of this syscall.

UPSTREAM: seccomp/cache: Lookup syscall allowlist bitmap for fast path
The overhead of running Seccomp filters has been part of some past discussions [1][2][3]. Oftentimes, the filters have a large number of instructions that check syscall numbers one by one and jump based on that. Some users chain BPF filters which further enlarge the overhead. A recent work [6] comprehensively measures the Seccomp overhead and shows that the overhead is non-negligible and has a non-trivial impact on application performance. We observed some common filters, such as docker's [4] or systemd's [5], will make most decisions based only on the syscall numbers, and as past discussions considered, a bitmap where each bit represents a syscall makes most sense for these filters. The fast (common) path for seccomp should be that the filter permits the syscall to pass through, and failing seccomp is expected to be an exceptional case; it is not expected for userspace to call a denylisted syscall over and over. When it can be concluded that an allow must occur for the given architecture and syscall pair (this determination is introduced in the next commit), seccomp will immediately allow the syscall, bypassing further BPF execution. Each architecture number has its own bitmap. The architecture number in seccomp_data is checked against the defined architecture number constant before proceeding to test the bit against the bitmap with the syscall number as the index of the bit in the bitmap, and if the bit is set, seccomp returns allow. The bitmaps are all clear in this patch and will be initialized in the next commit. When only one architecture exists, the check against architecture number is skipped, suggested by Kees Cook [7].

bpf: Fix propagation of 32-bit signed bounds from 64-bit bounds.
The 64-bit signed bounds should not affect 32-bit signed bounds unless the
verifier knows that upper 32-bits are either all 1s or all 0s. For example the
register with smin_value==1 doesn't mean that s32_min_value is also equal to 1,
since smax_value could be larger than 32-bit subregister can hold.
The verifier refines the smax/s32_max return value from certain helpers in
do_refine_retval_range(). Teach the verifier to recognize that smin/s32_min
value is also bounded. When both smin and smax bounds fit into 32-bit
subregister the verifier can propagate those bounds.

membarrier: Execute SYNC_CORE on the calling thread
membarrier()'s MEMBARRIER_CMD_PRIVATE_EXPEDITED_SYNC_CORE is documented as
syncing the core on all sibling threads but not necessarily the calling
thread. This behavior is fundamentally buggy and cannot be used safely.
Suppose a user program has two threads. Thread A is on CPU 0 and thread B
is on CPU 1. Thread A modifies some text and calls
membarrier(MEMBARRIER_CMD_PRIVATE_EXPEDITED_SYNC_CORE).
Then thread B executes the modified code. If, at any point after
membarrier() decides which CPUs to target, thread A could be preempted and
replaced by thread B on CPU 0. This could even happen on exit from the
membarrier() syscall. If this happens, thread B will end up running on CPU
0 without having synced.
In principle, this could be fixed by arranging for the scheduler to issue
sync_core_before_usermode() whenever switching between two threads in the
same mm if there is any possibility of a concurrent membarrier() call, but
this would have considerable overhead. Instead, make membarrier() sync the
calling CPU as well.
As an optimization, this avoids an extra smp_mb() in the default
barrier-only mode and an extra rseq preempt on the caller.

membarrier: Explicitly sync remote cores when SYNC_CORE is requested
membarrier() does not explicitly sync_core() remote CPUs; instead, it
relies on the assumption that an IPI will result in a core sync. On x86,
this may be true in practice, but it's not architecturally reliable. In
particular, the SDM and APM do not appear to guarantee that interrupt
delivery is serializing. While IRET does serialize, IPI return can
schedule, thereby switching to another task in the same mm that was
sleeping in a syscall. The new task could then SYSRET back to usermode
without ever executing IRET.
Make this more robust by explicitly calling sync_core_before_usermode()
on remote cores. (This also helps people who search the kernel tree for
instances of sync_core() and sync_core_before_usermode() -- one might be
surprised that the core membarrier code doesn't currently show up in a
such a search.)

membarrier: Add an actual barrier before rseq_preempt()
It seems that most RSEQ membarrier users will expect any stores done before
the membarrier() syscall to be visible to the target task(s). While this
is extremely likely to be true in practice, nothing actually guarantees it
by a strict reading of the x86 manuals. Rather than providing this
guarantee by accident and potentially causing a problem down the road, just
add an explicit barrier.
