to the healthd_config to instruct BatteryMonitor of the power supply paths
to ignore on init.

Don't create separate mount namespaces for pre-apexd processes
Bionic libs are located at /system/lib
Bionic libs and the dynamic linker are bind mounted
It is causing problem to the sdcardfs. Specifically, re-mounting events
for /mnt/runtime/{runtime|write} done by the vold process (which is a
pre-apexd process) are not being propagated to other mount namespaces.
As a result, SDCard access isn't working.
The propagation problem is a bug in sdcardfs which is fixed by [1].
However, we can't make all Android devices to have the patch at the same
time. Therefore, by default the separate mount namespace is not created
and will be created only for the devices where the kernel patches are in and
ro.apex.bionic_updatable sysprop is set to true.

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

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.

are from system partition.

This commits allows multiple lines in a fstab have the same mount
point for first-stage mount, where the first successful mount will be
used.
This allows us to specify a common/shared fstab, with different
settings (e.g., ext4, squashfs) per line, to mount different types
of images on the same mount point. e.g., allows the device to mount
GSI (ext4) while support mounting the original squashfs system.img.
Sample fstab:
fstab in dt:
android {
fstab {
odm_ext4 {
dev = "/dev/block/by-name/odm";
mnt_point = "/odm";
type = ext4;
mnt_flags = "ro";
fs_mgr_flags = "slotselect";
};
odm_f2fs {
dev = "/dev/block/by-name/odm";
mnt_point = "/odm";
type = f2fs;
mnt_flags = "ro";
fs_mgr_flags = "slotselect";
};
};
}
fstab in file:
/dev/block/by-name/odm /odm ext4 ro slotselect
/dev/block/by-name/odm /odm f2fs ro slotselect
Test: make & boot & check /proc/mounts

This commit has the following changes:
1. Builds libfs_avb via "fs_mgr/libfs_avb/Android.bp" instead of
"fs_mgr/Android.bp", and removes the libfs_avb source
dependencies on "fs_mgr/fs_mgr_priv.h".
2. Moves static functions in fs_avb.cpp into util.cpp or
avb_util.cpp, depending on whether the function is related to
AVB or not.
3. Introduces two host unit tests: libfs_avb_test and
libfs_avb_internal_test, the former is to test public
<fs_avb/fs_avb.h> APIs, while the latter is to test libfs_avb
internal functions.
4. Splits fs_avb_unittest_util.* into:
- fs_avb_test_util.* (host static lib: libfs_avb_test_util),
- basic_test.cpp (host executable: libfs_avb_test)
