53089aa25c init: Use std::string for write_file()
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.

Test: Boot bullhead, run unit tests

e78ea77f69 bootstat: Refactor init/utils/boot_clock into base/chrono_utils.
Use this for bootstat and init. This replaces the custom uptime parser in
bootstat.

This change also has clang_format fixes (automatic).

8d01f63f50 remove emergency shutdown and improve init's reboot logic
- Emergency shutdown just marks the fs as clean while leaving fs
  in the middle of any state. Do not use it anymore.

- Changed android_reboot to set sys.powerctl property so that
  all shutdown can be done by init.

- Normal reboot sequence changed to
    1. Terminate processes (give time to clean up). And wait for
      completion based on ro.build.shutdown_timeout.
        Default value (when not set) is changed to 3 secs. If it is 0, do not
        terminate processes.
    2. Kill all remaining services except critical services for shutdown.
    3. Shutdown vold using "vdc volume shutdown"
    4. umount all emulated partitions. If it fails, just detach.
       Wait in step 5 can handle it.
    5. Try umounting R/W block devices for up to max timeout.
      If it fails, try DETACH.
      If umount fails to complete before reboot, it can be detected when
      system reboots.
    6. Reboot

- Log shutdown time and umount stat to log so that it can be collected after reboot

- To umount emulated partitions, all pending writes inside kernel should
  be completed.
- To umount /data partition, all emulated partitions on top of /data should
  be umounted and all pending writes should be completed.
- umount retry will only wait up to timeout. If there are too many pending
  writes, reboot will discard them and e2fsck after reboot will fix any file system
  issues.

bug: 36004738
bug: 32246772

Test: many reboots combining reboot from UI and adb reboot. Check last_kmsg and
      fs_stat after reboot.

40578ab91f init: Fix leaking fd and error print
read_file() does not close its fd if either stat() fails or the file
has group/world writable permissions.

Use unique_fd to ensure that all return paths close the fd and make
the same change to write_file() for consistency.

Replace PLOG() with LOG() after a simple if conditional, that does not
set errno.

Old:
init: skipping insecure file '/data/bootchart/header': No such device or address
New:
init: skipping insecure file '/data/bootchart/header'

Test: Cause an invalid file read and check the error log
Test: Ensure non-error read_file() and write_file() work

978fd0ea25 init: service file command only opens existing files
Mixing open or create, along with attribute(MAC) and permissions(DAC)
is a security and confusion issue.

Fix an issue where fcntl F_SETFD was called to clear O_NONBLOCK, when
it should have been F_SETFL.  Did not present a problem because the
current user of this feature does writes and control messages only.

d1d3bdd16f Only restorecon CE storage after unlocked.
On FBE devices, the filenames inside credential-encrypted directories
are mangled until the key is installed.  This means the initial
restorecon at boot needs to skip these directories until the keys
are installed.

This CL changes the implementation of the "restorecon_recursive"
built-in command to use the new SKIPCE flag to avoid labeling files
in CE directories.  vold will request a restorecon when the keys
are actually installed.

9605a945f7 init start time tracking.
With this change, init sets a property "init.start" to show the
CLOCK_BOOTTIME time at which init itself started, and for each service
an "init.svc.<name>.start" property to show the CLOCK_BOOTTIME time at
which that service was most recently started.

These times can be used by tools like bootstat to track boot time.

As part of this change, move init over to std::chrono. Also, rather than
make the command-line argument handling more complex, I've switched to
using an environment variable for communication between first- and
second-stage init, and added another environment variable to pass the
start time of the first stage through to the second stage.

83ccb1c76b init: Don't ignore setsockcreatecon errors
The init language supports setting the creation context of a socket
as the 6th argument to the socket keyword. For example, in the
following service, the context associated with the netd socket
is u:r:netd:s0

service netd /system/bin/netd
    class main
    socket netd stream 0660 root system u:r:netd:s0
    socket dnsproxyd stream 0660 root inet
    socket mdns stream 0660 root system
    socket fwmarkd stream 0660 root inet

The 6 argument form of the socket statement is rarely if ever used,
since the init code supplies a sensible default.

Currently, there's no error checking on the value supplied as
the 6th argument. For example, if you have the following socket
statement:

  socket netd stream 0660 root system graphics

a socket will attempt to get created with an invalid "graphics"
context. When setsockcreatecon fails, it retains the default socket
creation context, which for init is u:r:init:s0. This results in a
socket being created which is in an unexpected context.

Check the return value from the setsockcreatecon() call. If an
invalid context is specified, return early and don't subsequently
attempt to create the socket with the default context.

b7349902a9 init: Use classes for parsing and clean up memory allocations
Create a Parser class that uses multiple SectionParser interfaces to
handle parsing the different sections of an init rc.

Create an ActionParser and ServiceParser that implement SectionParser
and parse the sections corresponding to Action and Service
classes.

Remove the legacy keyword structure and replace it with std::map's
that map keyword -> (minimum args, maximum args, function pointer) for
Commands and Service Options.

Create an ImportParser that implements SectionParser and handles the
import 'section'.

Clean up the unsafe memory handling of the Action class by using
std::unique_ptr.

d2104df69b init/util.cpp: don't return a negative unsigned value
android_name_to_id() returns -1U on error, which causes a
crash when the following clang options are enabled:

  -fsanitize=signed-integer-overflow,unsigned-integer-overflow
  -ftrap-function=abort
  -fsanitize-undefined-trap-on-error

Rather than returning a negative unsigned value (which doesn't
make a lot of sense, IMHO), return a positive unsigned value.

While we're here, add logging on decode_uid failures.

91cf41cf43 init: wait_for_file use smaller time resolution
As 1s timeout can be requested, using second resolution time to check
for timeout prevent from being accurate on the actual time we wait.
Use available gettime_ns instead.
