These were leftovers from the SELinux boolean support that
was originally merged.  Since Android prohibits SELinux policy
booleans, we can just drop it.

Yongqin Liu a197ff12dd bootchart: fix bootchart can not be triggered problem
bootchart uses a file on the data partition to decide if it should collect
data for bootchart, but the data partition will be mounted by the mount_all
command in the "on fs" section, and it will be only added into the action
queue when command "trigger fs" is executed, but that's after the
bootchart_init action (late_init).

This change makes bootchart_init a builtin command of init,
and make it executed as the first command of "on post-fs" section
which will be triggered after the "on fs" section.

This change also refactors the bootchart code to all be in bootchart.cpp.

Johan Redestig 7e952f41f1 Bump do_write buffer size
In the case of do_write (write to generic file) there
is really no relation to the PROP_VALUE_MAX limitation
of system properties. The current value, 92, is not so
much for writing to files so bump it a bit.

Ideally there should not be any low hard limit in this
case. Either expand_props should allocate the output
buffer or take the output fd and to streaming write.
Such a change is rather invasive though and at this
point in time it seems reasonable that one dont want
more than 256 character strings in the init files.

Elliott Hughes f682b4786a Clean up reading and writing in init.
This isn't particularly useful in and of itself, but it does introduce the
first (trivial) unit test, improves the documentation (including details
about how to debug init crashes), and made me aware of how unpleasant the
existing parser is.

I also fixed a bug in passing --- unless you thought the "peboot" and "pm"
commands were features...

"&&" operator can now be used to test the validity
of two of more properties.

For example:

both test.a=1 and test.b=1

Nick Kralevich bc60954fae builtins.c: Don't require file open() for chmod/chown
42a9349dc4 modified init's
builtin chmod, chown, and mkdir calls to avoid following
symlinks. This addressed a number of attacks we were seeing
at the time where poorly written init scripts were following
attacker supplied symlinks resulting in rooting vulnerabilities.

To avoid race conditions, the previous implementation only ran
fchown / fchmod on file descriptors opened with open(O_NOFOLLOW).
Unfortunately, unlike the normal "chown" or "chmod" calls, this
requires read or write access to the underlying file. This
isn't ideal, as opening some files may have side effects, or
init may not have permission to open certain files (such as when
SELinux is enabled).

Instead of using open(O_NOFOLLOW) + fchown(), use lchown() instead.
As before, the target of the symlink won't be modified by chown.
This also supports setting the ownership of symlinks.

Instead of using open(O_NOFOLLOW) + fchmod(), use
fchmodat(AT_SYMLINK_NOFOLLOW) instead. As before, the target of the
symlink won't be modified by chmod.

This change will continue to ensure that chown/chmod/mkdir doesn't
follow symlinks, without requiring init to open every file in
read-only or read-write mode.

This change depends on bionic commit I1eba0cdb2c509d9193ceecf28f13118188a3cfa7

Addresses the following mako/occam SELinux denial:

  audit(1422770408.951:6): avc:  denied  { write } for  pid=1 comm="init" name="smd7" dev="tmpfs" ino=7207 scontext=u:r:init:s0 tcontext=u:object_r:radio_device:s0 tclass=chr_file
