Now all somewhat time-consuming methods of the VibratorService
are surrounded by traceBegin/traceEnd blocks.
The vibration itself is surrounded with asyncTrace block.
Test: Run "systrace vibrator" and see the time consumption report.

Multiple LTP tests require a "daemon" or "bin" user. These user ids
have been defined since UNIX incept, and even up to the '80s remained
in many of the tools as hard coded values. Add these two ids with
a cautionary note.

For processes that start very early, atrace initialization can cause
an selinux denial, so make sure it's possible to disable it and avoid
the call to open "trace_marker".
Bug: 63927601
Test: disable atrace early in vold, ensure that selinux denial is
avoided.

There may be evidence of ashmem_valid(fd) reporting that the file
descriptor is an ashmem node. Increase testing of ashmem_valid(fd),
reporting that the node _is_ ashmem, to inspire confidence in the
positive result. Scan all file descriptors in the system, and for
those that pass ashmem_valid, get a non-zero size reference back.
Some clang-format-isms applied.
Test: libcutils-test --gtest_filter=AshmemTest.*

Filesystems allow the setting of the "resgid" parameter to designate
a GID that is allowed to use the "reserved" disk space (in addition
to UID 0). We'll be granting this GID to critical system processes,
so that the system is usable enough for the user to free up disk
space used by abusive apps.

AID_SHARED_GID is a GID shared by a specific app across all users on
the same device. Bring the UserHandle and multiuser.c implementations
into agreement, and copy/paste the unit tests that verify that both
behave identically.
This fixes a regression where multiuser_get_shared_gid() was applying
per-user isolation when it shouldn't have.

Just the minimial changes to get this to actually build, because otherwise
we always bog down trying to rewrite everything (when the real answer
is usually "stop using libcutils, it's awful").
This doesn't move a handful of files: two are basically just BSD libc
source, a couple have outstanding code reviews, and one can be deleted
(but I'll do that in a separate change).
I'm also skipping the presubmit hooks because otherwise clang-format
wants to reformat everything. I'll follow up with that...

In order to replace qtaguid module with new eBPF network monitoring
module. We firstly move the current qtaguid userspace implementation
into netd and hide the detail from other processes. The current API will
talk to netd fwmark client to pass down the qtaguid related request from
high level framework and netd will use the proper method to complete the
request.
Test: Current TrafficStats CTS tests should not fail.

The qtaguid kernel module will be deprecated on devices running 4.9
kernel or above and we need to support both old and new module in
userspace. Netd is responsible for choosing which kernel module to use
and all the current qtaguid native implementation need to be hided
behind it. So the current qtaguid native API implementation will be
moved to a isolate library under system/core and only netd can access to
it. The libcutils qtaguid API will become a wrapper to send request to
netd module. This modification will make sure the apps that currently
using this native API will not be broken.
Bug: 30950746
Test: All cts and vts test related should not fail.

The parent change ran into an issue where enabling UBSan on an i686
build caused it to use __mulodi4.

libclang_rt.builtins-i686.a, but that's not available from soong either.

This change adds user namespace-awareness to uevent_kernel_* in
libcutils. Instead of assuming that root is always uid 0, it detects
whether the uid 0 is mapped in the current user namespace and returns
the appropriately mapped uid (or the kernel's "overflowuid" in case it
is not mapped).
In older kernels, or those where user namespaces are not enabled, this
still uses uid 0 for root.

Adding functionality to bootstat --record_boot_complete and
--record_boot_reason to initialize sys.boot.reason, the canonical
system boot reason.
Filter out ro.boot.bootreason oem noise into sys.boot.reason. Add
heuristics to determine what the boot reason is, when otherwise would
be defaulting to the blunt and relatively devoid of detail catch-all
reboot reasons ("reboot", "shutdown", "cold", "warm", "hard").
boot_reason_test.sh is also a compliance test.

Switch from /data/misc/reboot/last_reboot_reason to persistent
Android property persist.sys.boot.reason for indicating why the
device is rebooted or shutdown.
persist.sys.boot.reason has a standard as outlined in b/63736262 and
the associated investigation. Made adjustments to the values so that
we did not create a problem even before we started. Compliance is
part of the tests in boot_reason_test.sh.
