init used to block on installkey such that it was unable to
process property events. This lead to a deadlock by which
the Keymaster HAL would wait indefinitely for the
hwservicemanager.ready=true.
This fixes the issue by implementing the builtin in terms of
do_exec, which allows init to stay responsive to properties
while waiting for the child to terminate.

Exec services may also want to set other service flags such as
priority. Instead of expanding the exec syntax to handle this, create
a new command, exec_start, that will treat an existing service
definition as an exec service. The new exec_start command will start
the service then halt init from executing further commands until the
service has exited.
This change additionally encapsulates the waiting_for_exec logic into
ServiceManager and removes the ambiguous 'bool' return value from
Reap() which previously indicated if a Reaped service was an exec
service or not.

Currently, when we are waiting for an exec service or a property, if
there are either any services to be restarted or any more commands to
be run, we set the epoll_timeout to handle these events. However, we
don't actually restart and processes or execute any commands while
waiting, so this essentially turns this waiting into a spin loop,
particularly in the common case of having more commands to execute,
where epoll_timeout is set to 0.
The change only sets epoll_timeout if we're not waiting.
Note that the only way to stop waiting for an exec service or a
property is for a signal or property to be delivered to init, which
happens through the epoll fds, so it's safe to indefinitely wait for
epoll to return.

- 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

Currently, if init crashes, the kernel panics. During development, we

into bootloader. This will prevent boot looping bad configurations,

Normally 'writepid' is used to add a process to a particular cpuset. However
certain systems with big/small cores might need to specify a default cpuset for
system processes which do not explicitly specify one. Add an option to use
'ro.cpuset.default' system property to specify default cpuset for system processes
which do not explicitly write to /dev/cpuset/... with 'writepid' option.
The cpuset name specified in ro.cpuset.default is just the cpuset name, e.g.
'/system-background', '/foreground', or simply '/' for the "root" cpuset.

A recent change to the is_first_stage conditionals created a unneeded
else { } block as both the code in the else { } block and any code
that runs after it are both in the second stage of init. A first step
to clean this up is to remove this else block.
Secondly, given the above confusion, it makes sense to simplify the two
if (is_first_stage) conditions into one, which only now requires
duplicating one line to initialize logging and the actual "init
first/second stage started!" logs.
Lastly, there are a few commands ran at the beginning of both init
stages that do not need to be,
* boot_clock::time_point start_time = boot_clock::now();
This is only used in the first stage so keep it there
* umask(0);
umasks are preserved across execve() so it only needs to be set in the
first stage
* chmod("/proc/cmdline", 0440);
This needs to be moved until after /proc is mounted in the first
stage, but otherwise only needs to be done once

This change makes init's SELinux policy compilation step target the

disables clang-format for this section of code and formats the code

NOTE: This change affects only devices which use SELinux kernel policy
split over system and vendor directories/partitions.
Prior to this change, init compiled sepolicy from *.cil files on every
boot, thus slowing boot down by about 400 ms. This change enables init
to skip the step compilation and thus avoid spending the 400 ms. The
skipping occurs only if the device's vendor partition includes an
acceptable precompiled policy file. If no acceptable policy is found,
the compilation step takes place same as before.
Because such devices support updating system and vendor partitions
independently of each other, the vendor partition's precompiled policy
is only used if it was compiled against the system partition's policy.
The exact mechanism is that both partitions include a file containing
the SHA-256 digest of the system partition's policy
(plat_sepolicy.cil) and the precompiled policy is considered usable
only if the two digests are identical.
Test: Device with monolithic policy boots up just fine
Test: Device with split policy and with matching precompiled policy
boots up just fine and getprop ro.boottime.init.selinux returns

Test: Device with split policy and with non-matching precompiled
policy boots up just fine and getpropr ro.boottime.init.selinux
returns a number above 400 ms. There is a "Compiling SELinux
policy" message in dmesg. The non-matching policy was obtained
by adding an allow rule to system/sepolicy, building a new
system image using make systemimage and then flashing it onto
the device.

This makes the build system include split SELinux policy (three CIL
files and the secilc compiler needed to compile them) if
PRODUCT_FULL_TREBLE is set to true. Otherwise, the monolitic SELinux
policy is included.
Split policy currently adds around 400 ms to boot time (measured on
marlin/sailfish and bullhead) because the policy needs to be compiled
during boot. This is the main reason why we include split policy only
on devices which require it.

This modifies init's loading of SELinux policy into the kernel to
load the split (platform/system vs non-platform/vendor) policy if it's
present. If the split policy is not present, the usual monolithic
policy is loaded into the kernel, same as before.
Split policy is loaded by first compiling it from CIL form using
secilc compiler into the conventional monolithic/compiled form which
is then loaded into the kernel.
The build system has not yet been modified to place split policy onto
devices. Thus, this commit currently has no effect. For testing split
policy, build plat_sepolicy.cil, nonplat_sepolicy.cil, and
mapping_sepolicy.cil, and place them into the root directory of the
device.

With init parsing fstab fragments from kernel separately, the fs_mgr
would completely miss the device tree entries. That leads to things like
'adb remount' to go through without warning for verity even if /system
is verified. This happens because 'verity_update_state' completely
misses the partitions passed to android through the device tree.
solution is to teach fs_mgr about device tree fstab entries and add 2
new public APIs.
1. fs_mgr_read_fstab_dt() - reads device tree and returns fstab
generated from it.
2. fs_mgr_read_fstab_default() - reads both device tree fstab and
/fstab.{ro.hardware} and returns the combined table.
This also reduces the hardcoded /fstab.{ro.hardware} occurence only to
fs_mgr and for eveyone who wants to read the "default" fstab must be
changed to call fs_mgr_read_fstab_default() instead. e.g. adb.

Most devices pass the veritymode through 'androidboot.veritymode' kernel

odm partitions (also system in case of non-A/B devices). Also, that
needs to be independent of kernel cmdline since the cmdline will likely
exceed its limit.
The change adds support for parse and create fstab entries that can be
directly sent to the fs_mgr for mounting partitions early in init first
stage.
Sample DT entry to mount vendor partition early on angler-
firmware {
android {
compatible = "android,firmware";
fstab {
compatible = "android,fstab";
vendor {
compatible = "android,vendor";
dev = "/dev/block/platform/soc.0/f9824900.sdhci/by-name/vendor";
type = "ext4";
mnt_flags = "ro,barrier=1,inode_readahead_blks=8";
fsmgr_flags = "wait";
};
};
};
};

Test: Boot angler and sailfish with early "vendor" partition mount by
adding aforementioned DT node and enable CONFIG_PROC_DEVICETREE in kernel

This is done by parsing 'androidboot.fstab=<fstab>' kernel cmdline
option to get the fstab file that *only* specifies partitions to be
mounted early (i.e. in init's first stage).
Note that, the same fstab file may not be used as an argument to
mount_all later in the boot as that will cause fs_mgr to fail with
EBUSY.
TODO:
- Possibly add a new mount_mode so the same fstab can be used for
early_mount, 'mount_all --early/--late' etc.
- Add support for dm-verity enabled partitions to mount early.
- Add support for getting fstab arguments through DT instead of kernel
cmdline.
Bug: 27805372
Test:
Boot angler by passing a seperate fstab file using the kernel
cmdline option to mount vendor partition early, remove the vendor
partition entry from the main fstab file for the test.
Boot sailfish by passing a seperate fstab entry via device tree
to mount vendor partition early. Remove vendor partition entry from
the main fstab file for the test

We don't want to spend time creating devices that are unncessesary
during early (init first-stage) mount. So, refactor the devices code
tha allows us to call into coldboot and has the
- ability to only create devices that are specified by the caller
- ability to stop coldboot cycle when all devices that the caller is
interested in
- ability to run coldboot for a specific syspath
- ability to run ueventd code unmodified
Test: Tested boot on angler, sailfish

I find myself using something like this every time I add functionality
to init. I cannot possibly be the only one doing this. On the other
hand, if this hasn't been added for so long, maybe there's a reason
for that.
The advantage of using a test service versus modifying an existing
service is that the test service doesn't *require* any permissions or
privileges, so you can add and/or remove whatever you need to test
without breaking the service.
I found it useful to have the service check its own /proc/<pid>/status
from command-line arguments, so that's what the service does.
This CL also adds a .clang-format file for init.
Bug: None
Test: Service runs and exits successfully.

This is to setup a way for us to run coldboot during init first stage
and also at ueventd startup. We do not have all of the file context
during the first stage, so the "early" coldboot needs to proceed without
labelling the device nodes. However, the follow up in ueventd must label
these nodes. This change allows us to do both.
