Michael Wright 95637eb2a3 Only allow system to write to existing input nodes. 
This prevents the shell user from injecting input as if it were coming
from an existing input device, which in turn makes it easier for malware
/ abuse analysis to detect when someone is injecting input via the
command line vs a real user using a device.

Bug: 30861057
Test: ran getevent, saw correct output, played with device

Josh Gao 42a0fed78b init: don't start tombstoned until /data is mounted. 
When vold mounts the encrypted /data partition, it first checks for and
kills processes that have open fds to the tmpfs placeholder at /data.
This resulted in a 20 second boot-time regression (vold's timeout period)
when tombstoned was started before vold.

Bug: http://b/34461270
Test: boot is faster, no messages from vold in console spew
Test: tombstoned still started by init

A TOCTOU race can occur between listing threads and attaching them.
Don't abort and leave the process in a stopped state when this happens.

Mark Salyzyn 142b43d4ab liblog: BM_log_latency improvement 
This reduces BM_log_latency from ~300ns to ~100ns.  Because, well, we
read the clock earlier and that is what BM_log_latency tries to
measure.  The one major improvement in the switch from kernel logger
to user space logger was that we picked up the timestamp in the
context of the caller before doing anything else, but alas changes
over time neglected this fact and placed isloggable checking ahead
of this important fact.

Test: liblog_benchmarks, check results

Mark Salyzyn c3c06294e5 logd: test: switch to /data/backup/ for sepolicy avc injection 
Resolve issues seen on continuous testing frame:

- statistics test, info instead of fail on missing radio log data.
- sepolicy switch from /data/misc/logd/ to /data/backup/ as the
  directory we access(2) to inject sepolicy violations.  The key here
  is we are still root, but we are in u:r:shell:s0, and the directory
  does not provide us DAC access (0700 system system) so we trigger
  the pair dac_override and dac_read_search on every try to get past
  the message de-duper.  /data/misc/logd is not always there, until
  logpersist is enabled, but /data/backup is always there.
- a stricter signature of '): avc: denied'
- put in a looser threshold for sepolicy_rate_limiter_spam test.

Test: gTest logd-unit-tests --gtest_filter=logd.sepolicy*

Dave Weinstein 44f7e4f421 Move the kptr_restrict setting from init.rc to init.cpp. 
Also ensure that it uses the highest supported value, and
abort if the value is not above a minimum threshold.

Test: Tested against the curent kernel (maximum value of 2,
      set to 0 by the kernel initially) and against a
      modified kernel (maximum value of 4, set to 4 by the
      kernel initially)
