libprocessgroup users use libcutils

2019-06-18T22:03:54+00:00

libprocessgroup symbols are being moved into libcutils in order to
optimize linking/memory usage. libprocessgroup will no longer be
required in the future (however removing references to it will come
separately).

Bug: 135145426
Test: boot

Test:
BEFORE:
$ adb shell showmap -a $(pid hwservicemanager) | grep -P "libprocessgroup|libcutils" -A1 | grep -P 'libprocessgroup|libcutils|\.bss' | awk '{s += $9}END{print s}'

AFTER:
$ adb shell showmap -a $(pid hwservicemanager) | grep -P "libprocessgroup|libcutils" -A1 | grep -P 'libprocessgroup|libcutils|\.bss' | awk '{s += $9}END{print s}'

Moving /odm/build.prop to /odm/etc/buid.prop

2019-05-22T08:15:44+00:00

In device root directory, we have the following symlinks:
  - /odm/app -> /vendor/odm/app
  - /odm/bin -> /vendor/odm/bin
  - /odm/etc -> /vendor/odm/etc
  ...

This allows the Generic System Image (GSI) to be used on both devices:
  1) Has a physical odm partition, where those symlink will be hidden
     when /odm is used as the mount point
  2) Has no physical odm partition and fallback to /vendor/odm/.

We can't just have the symlink /odm -> /vendor/odm, because the former
devices won't have /vendor/odm directory, which leads to mount failure
when the mount point /odm is resolved to /vendor/odm.

The existing /vendor/odm/build.prop won't be loaded in the latter
devices, because there is no symlink
    - /odm/build.prop -> /vendor/odm/build.prop.

Note that init blocks reading through direct symlinks (O_NOFOLLOW) so
the above symlink won't work either. This CL moves the odm build.prop
to /odm/etc/build.prop for init to load it (symlinks in earlier
components of the path will still be followed by O_NOFOLLOW).

Test: boot a device and checks /odm/etc/build.prop is loaded

cutils: add ashmem_init

2019-04-05T00:28:05+00:00

Add a new ashmem_init function that only dlopens libashmemd_client.
This allows the library to be preloaded in the zygote.

Test: boots, works

libprocessgroup: use libcgrouprc to read cgroup.rc

2019-04-03T00:34:37+00:00

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.

libcutils: android_reboot command should be unsigned.

2019-04-02T16:19:46+00:00

Hex literals have the type of the first type they fit in. The reboot
constants are large enough that that's `unsigned` rather than `int`.
