Perfetto is a tracing daemon that allows both to capture
traces from the kernel (via the traced_probes binary)
and allows data to be pushed from userspace (via the
traced binary). Tracing is never enabled by default
and can be kicked off either via statsd or by the shell.
The daemon executables are split only for the sake
of security and isolating SELinux domains. Under the
hoods they are just two shells that run code in the
same shared libarary.
See go/perfetto-sys-health-details for expected
binary / memory / overhead impact.
Bug: 72484603
Test: builds (see go/perfetto-test-spec for test plan)

Restrictions on usage of private APIs require encoding new information
into the dex files of the boot class path. ART now contains a new build
tool called `hiddenapi` which takes three lists of class member
signatures (blacklist, light and dark greylist), finds the class members
in their respective dex files and modifies their access flags in place.
This patch invokes the `hiddenapi` tool on all JARs in
PRODUCT_BOOT_JARS. For Java libraries built with Makefiles the tool is
invoked after the dexer directly on DEX files. For Soong-built
libraries, the build system has to unzip the JAR produced by Soong,
apply `hiddenapi` and rezip again. This is due to the fact that the
PRODUCT_BOOT_JARS variable is not available to Soong.

Add variables for the hidden API blacklist and dark and light greylist
files. These are text files with signatures of boot class path class
member with restricted access for non-platform code.

Label /sys/class/power_supply/* appropriately and give healthd read
permissions to that directory.
Fixes this denial:
avc: denied { read } for pid=1386 comm="healthd" name="power_supply"
dev="sysfs" ino=2562 scontext=u:r:healthd:s0
tcontext=u:object_r:sysfs:s0 tclass=dir permissive=0

Test: emulator boots with no denials from healthd

Earlier, we would use the prebuilt directly, which doesn't go through
build optimizations like uncompressing the dex files.
bug: 63920015
Test: m -j32 && verify priv-apps prebuilt's vdex don't contain
the dex code.

We need to prevent vendors from using old VNDK and SystemSDK versions
for newly launched device. Otherwise, deprecating old versions of the
APIs would be really difficult.
Specifically, it is enforced that
PRODUCT_SHIPPING_API_LEVEL <= BOARD_VNDK_VERSION
PRODUCT_SHIPPING_API_LEVEL <= min(BOARD_SYSTEMSDK_VERSIONS)
Bug: 72126206
Test: manually setting BOARD_VNDK_VERSION to 24 in
device/google/wahoo/BoardConfig.mk and choosecom to walleye
Test: m -j shows an error on BOARD_VNDK_VERSION
Test: BOARD_SYSTEMSDK_VERSION="25 26" m -j shows an error on
BOARD_SYSTEMSDK_VERSION

ld.config.noenforce.txt is defined as a module.
For GSI, install the module instead of copying it.

bsdiff/imgdiff returns non-zero values correctly in case of failures.
So we don't need to check the stderr anymore. This avoids some false
reports of the diff program.
Bug: 72335938
Bug: 71505046
Test: Check the exit value of bsdiff/imgdiff in code search,
generate a package for angler.

Add PLATFORM_SYSTEMSDK_VERSIONS to framework manifest
