First kill the process group before killing the cgroup to catch

Do not report an error if kill fails due to ESRCH, as this happens

waitpid() and kill().
Do not call killProcessGroup in libprocessgroup if we have already

Similar to what installkey used to do, init_user0 forks and
synchronously waits for vdc to return. This is dangerous to do in
init however as init also processes properties from a single thread.
I'm not aware of any specific issues that this is currently causing,
but it's a good preventative measure to match what installkey does and
use do_exec().

It has been reported that fs_mgr failed to open /dev/device-mapper
during the first stage mount. It's because other uevent (e.g., i2c
charger device) happens to be sent at the same time we're triggering
the device-mapper uevent to be sent. Current implementation returns
COLDBOOT_STOP unconditionally so it will only process the first received
uevent, leaving device-mapper uevent unhandled when the race happens.
Fix this by only returning COLDBOOT_STOP when the received uevent->path
matches that of device mapper.

Init exposes a global 'sehandle' that ueventd references as part of
devices.cpp and util.cpp. This is particularly dangerous in
device_init() in which both uevent and init write to this global.
This change creates a separate local copy for devices.cpp and puts
restrictions on where init.h can be included to make sure the global
used by init is not reference by non-init code. Future changes to
init should remove this global.

In the past, I had thought it didn't make sense to have multiple
Action classes with identical triggers within ActionManager::actions_,
and opted to instead combine these into a single action. In theory,
it should reduce memory overhead as only one copy of the triggers
needs to be stored.
In practice, this ends up not being a good idea.
Most importantly, given a file with the below three sections in this
same order:
on boot
setprop a b
on boot && property:true=true
setprop c d
on boot
setprop e f
Assuming that property 'true' == 'true', when the `boot` event
happens, the order of the setprop commands will actually be:
setprop a b
setprop e f
setprop c d
instead of the more intuitive order of:
setprop a b
setprop c d
setprop e f
This is a mistake and this CL fixes it. It also documents this order.
Secondly, with a given 'Action' now spanning multiple files, in order
to keep track of which file a command is run from, the 'Command'
itself needs to store this. Ironically to the original intention,
this increases total ram usage. This change now only stores the file
name in each 'Action' instead of each 'Command'. All in all this is a
negligible trade off of ram usage.
Thirdly, this requires a bunch of extra code and assumptions that
don't help anything else. In particular it forces to keep property triggers
sorted for easy comparison, which I'm using an std::map for currently,
but that is not the best data structure to contain them.
Lastly, I added the filename and line number to the 'processing
action' LOG(INFO) message.

(cherry picked from commit dbe88e7953)
The content parameter of write_file() previously took a char* that was
then converted to a std::string in WriteStringToFd(). One unfortunate
effect of this, is that it is impossible to write data that contains
'\0' within it, as the new string will only contain characters up
until the '\0'.
This changes write_file() to take an std::string, such that
std::string::size() is used to determine the length of the string,
allowing it to contain null characters.
Also change the path parameter of read_file() and write_file() for
consistency.
Lastly, add a test for handling strings with '\0' in them.

Currently if a process sets the sys.powerctl property, init adds this
property change into the event queue, just like any other property.
The actual logic to shutdown the device is not executed until init
gets to the action associated with the property change.
This is bad for multiple reasons, but explicitly causes deadlock in
the follow scenario:
A service is started with `exec` or `exec_start`
The same service sets sys.powerctl indicating to the system to
shutdown
The same service then waits infinitely
In this case, init doesn't process any further commands until the exec
service completes, including the command to reboot the device.
This change causes init to immediately handle sys.powerctl and reboot

ueventd: Fix up string handling in handle_*_device_event()
ueventd: convert mkdir_recursive() to std::string
ueventd: move subsystem logic from code to ueventd.rc
It's possible, in the event of a platform update, for the platform
SELinux policy to change from the policy on which the vendor SELinux
policy was originally based. In this case, a different mapping file
to bridge the differences between the new policy and the old needs to
be selected.
Make init choose which mapping policy file to use based on the version
reported in /vendor/etc/selinux/plat_sepolicy_vers.txt.
Bug: 36783775
Test: Force compilation of sepolicy on-device with mapping file changed
to new location and name, using the value reported on /vendor.

This was marked deprecated in 2014 and removed in 2015, let's remove
the uevent rule now too.
Test: see that logging still works on bullhead

- umount operation is asynchronous except for root partition.
Returning from umount does not guarantee completion of
umount. Poll /proc/mounts to confirm completion of umount.
- Treat all devices mounting to /data as emulated devices. This is
future proof when fs other than sdcardfs is used.
- Drop quota sync from sync step. There is no differences in
frequencies of quota error.
- Run umount in reverse order from mounting order so that any
hidden dependency can be auto-resolved.
- Add dump of lsof and /proc/mounts when umount fails. lsof only runs
when selinux is toggled into permissive mode. The dump is enabled
only for non-user build.
- Keep logcat until vold shutdown in case vold has any error to report.

unit tests.

Crashes that happen before tombstoned is running are extremely hard to
diagnose, because tombstones aren't written to disk, and the window of
opportunity to get logs via `adb logcat` is small (potentially
nonexistent).
Solve this by adding a world-writable /dev/kmsg_debug on userdebug
builds, and writing to it in addition to logcat when tombstoned hasn't
started yet.
Bug: http://b/36574794
Test: stop tombstoned; crasher; dmesg

Test: boot device with matching sha256 and non-matching and verify that
device boots and uses either precompiled or compiled policy as needed. Also
verify that mapping_sepolicy.cil has moved.

this will make the implementation more cleaner,
and has error message output when failed on some operations
also add the O_TRUNC flag explicitly for the open function
called in write_file.
And add more test on read_file and write_file functions
Bug: 36726045
Test: manual with hikey
Test: boot and init tests on bullhead
Test: cast with fugu, per b/36726045
