dimitry 051d5cba80 Enable native_bridge_support for libcutils
Android build system added support for building translated binaries
used on natively bridged targets (arm on x86 for example).

However in order to avoid building unnecessary binaries and libraries
for such architectures most modules do not support native bridge by default.

All needed modules have to explicitly indicate if they may be used as part
of translated binary build.

This change enabled native bridge support for libcutils which is a
greylisted library (available for apps targeting Android version < N).

Yifan Hong 53e0deb7b2 libprocessgroup: use libcgrouprc to read cgroup.rc
Use the LL-NDK library to read cgroup.rc.

As a side-effect, the CgroupController class is changed
to a wrapper of ACgroupController* from the library. The
class itself essentially becomes the pointer, and can be
trivially copied. Modify all client code for this change.

Steven Moreland e6132be529 libutils/libcutils: make host more like device
Having shared host libraries allows libraries depending on these to use
'shared_libs' for these. This simplifies configurations since these
libraries don't have to specify 'shared_libs' on all non-host targets.

Fix naming of libcutils_tests (plural) to match the singular that's more

Joel Fernandes 519440468b Add support for memfd
This patch adds support to make libcutils create and use memfd where
possible, instead of ashmem.

The libcutils library is made dynamic, since apps are still sending over
ashmem FDs to processes and we are working on moving those apps away
from ashmem. The best we can do for that is make the library work, and
force apps in the long run to move away from directly using ashmem.

Due to further complications mentioned in the 'NOTE' section of the
patch, memfd is kept disabled for now, so nothing changes yet. To enable
it, set the sys.use_memfd property (check user_debug build).

Logan Chien 25b742c627 libctuils: Exclude qtaguid.cpp from VNDK-SP variant
This commit excludes `qtaguid.cpp` from the VNDK-SP variant of
`libcutils.so` because the interface of `libnetd_client.so` may vary
between AOSP releases.

Besides, these functions don't work in vendor processes either because
VNDK-SP libraries are loaded in an isolated `vndk` linker namespace,
which cannot access `/system/lib[64]/libnetd_client.so` directly.  This
change makes it easier to spot the issue at build time and saves several
bytes.

Test: Build aosp_walleye-userdebug and
/system/lib[64]/vndk-sp-$VER/libctuils.so no longer exports qtaguid_*
functions.

Jeff Sharkey 53d37ba23f Better, consistent definition of AID_SHARED_GID.
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.

Elliott Hughes 8e9aeb9053 Move libcutils source to C++.
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...

Luis Hector Chavez e97a4b9799 libcutils: Make uevent_kernel_* namespace-aware
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.

Steven Moreland 385fe692cc libcutils: vendor_available
By setting vendor_available, the following may become true:

* a prebuilt library from this release may be used at runtime by
  in a later releasse (by vendor code compiled against this release).
  so this library shouldn't depend on runtime state that may change
  in the future.
* this library may be loaded twice into a single process (potentially
  an old version and a newer version). The symbols will be isolated
  using linker namespaces, but this may break assumptions about 1
  library in 1 process (your singletons will run twice).

Background:

This means that these modules may be built and installed twice --
once for the system partition and once for the vendor partition. The
system version will build just like today, and will be used by the
framework components on /system. The vendor version will build
against a reduced set of exports and libraries -- similar to, but
separate from, the NDK. This means that all your dependencies must
also mark vendor_available.

At runtime, /system binaries will load libraries from /system/lib*,
while /vendor binaries will load libraries from /vendor/lib*. There
are some exceptions in both directions -- bionic(libc,etc) and liblog
are always loaded from /system. And SP-HALs (OpenGL, etc) may load
/vendor code into /system processes, but the dependencies of those
libraries will load from /vendor until it reaches a library that's
always on /system. In the SP-HAL case, if both framework and vendor
libraries depend on a library of the same name, both versions will be
loaded, but they will be isolated from each other.

It's possible to compile differently -- reducing your source files,
exporting different include directories, etc. For details see:

https://android-review.googlesource.com/368372

None of this is enabled unless the device opts into the system/vendor
split with BOARD_VNDK_VERSION := current.

Isaac Chen 795267d4c7 Removed cpusets/schedboost build time dependency.
These two Soong product_variables were usually controlled by
ENABLE_CPUSETS and ENABLE_SCHEDBOOST in BoardConfig.mk. This change
turns the build time variables into runtime decision by checking if
a special file, "tasks", can be found under the mount points,
/dev/cpuset and /dev/stune, for cpusets and schedboost, respectively.

That special file only exists when the corresponding Linux kernel
configurations, CONFIG_CPUSETS and CONFIG_SCHEDTUNE, are set.

Vijay Venkatraman 3c6763ca21 Exporting C headers from system/core
Moved headers from include/libcutils and include/liblog to
libcutils/include and liblog/include respectively, so they can be
exported via these libs. They needed to be moved since Soong does
not allow export from external folder.

Added symlink from old locations. They are needed since Soong
includes system/core/include by default. Once all modules are
cleaned up to explicitly add the required libs, the symlinks will be
removed.

Also added liblog_vndk_headers that exports a special log/log.h for
VNDK.

Moved headers of libcutils to libcutils_headers. They should be used
by modules for header-only inlines. Added libcutils_headers as
dependency of libcutils.

Added libcutils_vndk_headers that exports a special cutils/log.h
deprecating usage of the file. A later CL will deprecate the one in
libcutils_headers

crashing processes.

Mark Salyzyn 52bd37e633 libcutils: move cutils/files.h to cutils/android_get_control_file.h
files.[h|cpp] is bound to be abused with junk, replace with
android_get_control_file.[h|cpp]. Plus some sundry cleanup.

Test: gTest libcutils-tests, logd-unit-tests, liblog-unit-tests,
      logcat-unit-tests and init_tests

Mark Salyzyn 0b034d9d7b libcutils: add android_get_control_file()
Solve one more issue where privilege is required to open a file and
we do not want to grant such to the service. This is the client side
of the picture, init is the server. The file's descriptor was placed
into the environment as "ANDROID_FILE_<path>" where non-alpha and
non-numeric characters in the <path> are replaced with _ and this
function picks the file descriptor up.

Added definition ANDROID_FILE_ENV_PREFIX ("ANDROID_FILE_") and
android_get_control_file() prototype in a new include <cutils/files.h>

android_get_control_file() checks if the resulting file descriptor is
valid, open and matches the name reference, which on purpose will fail
if a symbolic link is in the path rather than using a fully qualified
path.  Add gTest unit test for both.

Test: gTest libcutils_test --gtest_filter=FileTest.android_get_control_file
