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

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
link from namespaces containing /system/{lib,lib64,bin}.

The ICU .dat file was moved into the runtime APEX file
in commit b6d855f081c232309961f31c7c7c8a76abf79c3c.
There are some apps that know the old location and its
absence causes them to fail.
This change adds a symlink from the old directory to
the new directory. The ICU .dat file changes its name
with every ICU major release so this is simpler than
linking the file itself.

*/build.prop files are now loaded much earlier than before; from 'on
post-fs' to the time when the property service is started which is
before init starts the action loop.
This ensures that all processes that are launched by init have a
consistent view of system properties. Previously, the processes that
started before 'on post-fs' were initially with the small number of
sysprops loaded from */default.prop and then suddenly get additional
sysprops from */build.prop while they are executing.

Bionic libs, regardless of whether they are bootstrap ones or from the
runtime APEX, are available via /system/lib. Since /system/lib is in the
search paths of the default(platform) namespace, there is no need to
list the bionic libs to the namespace link to the runtime namespace.

This change makes the bionic libs and the dynamic linker from the
runtime APEX (com.android.runtime) available to all processes started
after apexd finishes activating APEXes.
Specifically, the device has two sets of bionic libs and the dynamic
linker: one in the system partition for pre-apexd processes and another
in the runtime APEX for post-apexd processes. The former is referred as
the 'bootstrap' bionic and are located at
/system/lib/{libc|libdl|libm}.so and /system/bin/linker. The latter is
referred as the 'runtime' bionic and are located at
/apex/com.android.runtime/lib/bionic/{libc|libdl|libm}.so and
/apex/com.android.runtime/bin/linker.
Although the two sets are located in different directories, at runtime,
they are accessed via the same path: /system/lib/* and
/system/bin/linker ... for both pre/post-apexd processes. This is done
by bind-mounting the bootstrap or the runtime bionic to the same path.
Keeping the same path is necessary because there are many modules and
apps that explicitly or implicitly depend on the fact that bionic libs
are located in /system/lib and are loaded into the default linker
namespace (which has /system/lib in its search paths).
Before the apexd is started, init executes a built-in action
'prepare_bootstrap_bionic' that bind-mounts the bootstrap bionic to the
mount points. Processes started during this time are provided with the
bootstrap bionic. Then after the apexd is finished, init executes
another built-in action 'setup_runtime_bionic' which again mounts the
runtime bionic to the same mount points, thus hiding the previous mounts
that target the bootstrap bionic. The mounting of the runtime bionic
(which is only for post-apexd processes) is hidden from pre-apexd
processes by changing propagation type of the mount points to 'private'
and execute the pre-apexd processes with a new mount namespace using
unshare(2). If a pre-apexd process crashes and re-launched after the
apexd is on, the process still gets the bootstrap bionic by unmounting
the runtime bionic which effectively un-hides the previous bind-mounts
targeting the bootstrap bionic.

For consistency with APKs, signature verification is performed
in the system_server. This includes checking that the signature of
an updated install matches the signature of the active package that
it updates. For this, it requires search access to /data/apex and
read access to the files under that directory.

This commit removes the soname filter from the namespace fallback link
from `runtime` to `system` in the vendor process. This fixes the
problem that vendor process might fail to load `libnetd_client.so`,
`libc_malloc_debug.so`, `libc_malloc_debug_leak.so`, and other libc
dependencies.
This commit also removes the namespace fallback link from `runtime` to
`default` in the vendor process. According to the comments in [1], the
original intention was to allow the access to `/system/${LIB}` not
`/vendor/${LIB}`. Furthermore, `com.android.runtime` suppose to work
without libraries from `/vendor/${LIB}`.

This reverts commit a0d9f2fd6c.
Original change: Needs to support e.g. app_process in "default" ->
libnativehelper in "runtime" -> platform libs in "default" -> libc etc in "runtime".
Always make sure to switch namespaces when switching library paths between
/system and the APEX, so that internal library dependencies in both
locations are loaded from their own directory. E.g. libc++ and libbase live
in both places, and their dependents must always load the version they were
compiled with.
This CL also adds a temporary workaround to not break hwasan builds
(b/121038155).
