The old "time zone updates via APK" feature installs time zone data
files in /data. tzdatacheck is run during boot to guard against an
OTA leaving the data in /data older, or in a different format, than the
files that exist elsewhere on device. If such files existed the system
could use old versions of tzdb (and related) data or even end up
unstable.
Soon, the time zone data mainline module will be made "functionally
mandatory" by the removal of most time zone data files from the
runtime module APEX, i.e. the time zone data module cannot be absent,
and the runtime module won't have files to compare against.
This change modifies the command line args for tzdatacheck to reference
the contents of time zone data module instead of the runtime module.

The canonical location of the HWASAN runtime, an LL-NDK library, is being moved
to the runtime APEX. It is apparently the first LL-NDK library in the runtime
APEX that does not require a legacy symlink in /system/${LIB}. Therefore we
need to link the HWASAN runtime in the runtime namespace to various namespaces
so that the library can be loaded from outside of the namespace.
Also, add $SANITIZER_RUNTIME_LIBRARIES to
namespace.default.link.system.shared_libs. This is necessary because in
the accompanying Soong change, we cause the HWASAN runtime to be removed
from $LLNDK_LIBRARIES. In most cases, except for this one, this was a no-op
because we were already including both sets of libraries in shared_libs.

We used to start update_verifier after mounting userdata (post-fs-data),
as part of zygote-start. This leads to issues in practice for security
updates, where an A/B device falls back into the old slot (for any
reason, which unrelates to this change) but failing to boot due to
upgraded key blob. It essentially breaks the fallback capability offered
by A/B OTA.
This CL mitigates the issue by starting update_verifier early, before
mounting userdata. This avoids the device from falling back to the old
slot with an already-upgraded key blob. update_verifier loses the
opportunity of verifying _all_ the updated blocks based on the info
that's stored in userdata. Instead it will only trigger the minimal
read to finish the work of marking a successful boot. This is a
trade-off in P to avoid putting the device in a bad state after
fallback, which will be improved in Q by better handling the fallback
path in vold.
Bug: 131176531
Test: Flash and boot crosshatch. Check the start of update_verifier and
it marks a successful boot.

On devices that use FDE and APEX at the same time, we need to bring up a
minimal framework to be able to mount the /data partition. During this
period, a tmpfs /data filesystem is created, which doesn't contain any
of the updated APEXEs. As a consequence, all those processes will be
using the APEXes from the /system partition.
This is obviously not desired, as APEXes in /system may be old and/or
contain security issues. Additionally, it would create a difference
between FBE and FDE devices at runtime.
Ideally, we restart all processes that have started after we created the
tmpfs /data. We can't (re)start based on class names alone, because some
classes (eg 'hal') contain services that are required to start apexd
itself and that shouldn't be killed (eg the graphics HAL).
To address this, keep track of which processes are started after /data
is mounted, with a new 'mark_post_data' keyword. Additionally, create
'class_reset_post_data', which resets all services in the class that
were created after the initial /data mount, and 'class_start_post_data',
which starts all services in the class that were started after /data was
mounted.
On a device with FBE, these keywords wouldn't be used; on a device with
FDE, we'd use them to bring down the right processes after the user has
entered the correct secret, and restart them.

With the recent change that removed get_exported_namespace out of libdl,
the RenderScript SP-HAL stopped using android_dlopen_ext which it used
to load libRS_internal.so in the "rs" namespace. Instead, it now falls
back to the ordinary dlopen() call. The dlopen() call tries to load the
lib in the current namespace (which is sphal) and then falls back to the
linked namespaces: default, vndk, rs.
The problem is that rs is listed as the last namespace and therefore the
linker tries the namespace only when it failed to load the library in
other namespaces: default and vndk. libRS_internal.so is accessible to
both vndk and rs namespaces. So, the dlopen() call always goes into the
vndk namespace and there is no chance for the lib to be loaded in the rs
namespace.
To fix the problem, the rs namespace is placed before vndk so that the
namespace is tried first.

This is necessary to get the correct APEX namespace setup for apps that
executes binaries from there.
In older releases no linker config applied to binaries in /data, so the
fallback config in /system/bin/linker was used, which basically just looked
up libraries in /system/{lib,lib64}. With the introduction of APEXes that
location no longer contains the complete set of libraries, so this is
necessary to retain functional parity.
Strictly speaking this fallback rule should apply as last resort for a
binary in any location, but the linker does not accept "dir.system = /".

Change-Id: Ib0ca13edec38e68cba1fc2124465571feedc4be7
Summary: Boot sequence around apexd is changed to make it possible for
pre-apexd processes to use libraries from APEXes. They no longer need to
wait for the apexd to finish activating APEXes, which again can be
done only after /data/ is mounted. This improves overall boot
performance.
Detail: This change fixes the problem that processes that are started
before apexd (so called pre-apexd processes) can't access libraries
that are provided only by the APEXes but are not found in the system
partition (e.g. libdexfile_external.so, etc.). Main idea is to activate
system APEXes (/system/apex/*.apex) before /data is mounted and then
activate the updated APEXes (/data/apex/*.apex) after the /data mount.
Detailed boot sequence is as follows.
1) init prepares the bootstrap and default mount namespaces. A tmpfs is
mounted on /apex and the propagation type of the mountpoint is set to
private.
2) before any other process is started, apexd is started in bootstrap
mode. When executed in the mode, apexd only activates APEXes under
/system/apex. Note that APEXes activated in this phase are mounted in
the bootstrap mount namespace only.
3) other pre-apexd processes are started. They are in the bootstrap
mount namespace and thus are provided with the libraries from the system
APEXes.
4) /data is mounted. init switches into the default mount namespace and
starts apexd as a daemon as usual.
5) apexd scans both /data/apex and /system/apex, and activate latest
APEXes from the directories. Note that APEXes activated in this phase
are mounted in the default namespaces only and thus are not visible to
the pre-apexd processes.

Because /vendor is a symlink to /system/vendor on devices without a
dedicated /vendor partition, /system/vendor/lib/* needs to be added to
the permitted paths whereever /vendor/lib/* is permitted.
Reasoning:
Legacy devices are forced to use ld.config.legacy.txt, which is very
permissive. We can prolong support for them and enable them to use the
VNDK if we extend the search paths to include the resolved symlink dirs.

This change fixes the problem that apexd is delaying the entire boot
sequence while waiting for the loopback devices to be created. The delay
was as big as 50 ms per a loopback device.
With this change, apexd is started much earlier: from "on post-fs-data"
to "on init". When it is first started, it scans /system/apex to
determine the number of APEXes and creates that number of loopback
devices priori. Since then it enters into the binder loop.
When the data partition is mounted, init lets apexd to initiate the
apexd boot sequence where APEXes in /data is scanned, verified, and
activated. Since the creation of the loopback devices were requested far
before, it is very likely that dev nodes for the devices are ready at
this moment (even if not, this isn't a lose).

The sys.use_memfd property is set by default to false in Android
to temporarily disable memfd, till vendor and apps are ready for it.
The main issue: either apps or vendor processes can directly make ashmem
IOCTLs on FDs they receive by assuming they are ashmem, without going
through libcutils. Such fds could have very well be originally created with
libcutils hence they could be memfd. Thus the IOCTLs will break.
Set default value of sys.use_memfd property to true once the issue is
resolved, so that the code can then self-detect if kernel support is present
on the device. The property can also set to true from adb shell, for
debugging.

The vulkan runtime loads drivers into the sphal namespace and relies
on them being in the sphal search path so that it doesn't have to
hardcode /vendor/${LIB}/hw.
These paths used to be allowed, but were removed by commit 2498e1b
because they were believed not to be required. Things didn't break
immediately because the vulkan runtime has a (supposed to be
temporary) fallback to hw_get_module, which loads from
/vendor/${LIB}/hw using absolute paths.

This CL fixes the design problem of the previous mechanism for providing
the bootstrap bionic and the runtime bionic to the same path.
Previously, bootstrap bionic was self-bind-mounted; i.e.
/system/bin/libc.so is bind-mounted to itself. And the runtime bionic
was bind-mounted on top of the bootstrap bionic. This has not only caused
problems like `adb sync` not working(b/122737045), but also is quite
difficult to understand due to the double-and-self mounting.
This is the new design:
Most importantly, these four are all distinct:
1) bootstrap bionic (/system/lib/bootstrap/libc.so)
2) runtime bionic (/apex/com.android.runtime/lib/bionic/libc.so)
3) mount point for 1) and 2) (/bionic/lib/libc.so)
4) symlink for 3) (/system/lib/libc.so -> /bionic/lib/libc.so)
Inside the mount namespace of the pre-apexd processes, 1) is
bind-mounted to 3). Likewise, inside the mount namespace of the
post-apexd processes, 2) is bind-mounted to 3). In other words, there is
no self-mount, and no double-mount.
Another change is that mount points are under /bionic and the legacy
paths become symlinks to the mount points. This is to make sure that
there is no bind mounts under /system, which is breaking some apps.
Finally, code for creating mount namespaces, mounting bionic, etc are
refactored to mount_namespace.cpp

Make libdexfile_external.so accessible from binaries and libraries in /system.
The runtime namespace needs to be visible since libopenjdk is loaded through dlopen().
There are dependencies on libdexfile_external from some central libraries
that are widely used (b/123186083).
One example is vendor/bin/hw/android.hardware.media.omx@1.0-service, which
requries the link from "system" to "runtime" in the [vendor] section.
The direct dependants are libunwindstack and simpleperf, so it's enough to
