This reverts commit f1d3dbc32f.

With the following changes to move /sbin/adbd to /system/bin/adbd,
we don't need this workaround anymore.

Jerry Zhang ecee434fae adb: Use kernel aio for functionfs.
This method works around the downsides of
ENDPOINT_ALLOC, namely that it is not affected
by memory fragmentation and it uses an upstream
interface.

Also add libasyncio to provide the necessary syscalls
to both adb and mtp.

Add some small optimizations to file_sync.

Bowgo Tsai f1d3dbc32f adbd: lessen security constraints when the device is unlocked
ALLOW_ADBD_ROOT ('adb root') and ALLOW_ADBD_NO_AUTH (ro.adb.secure = 0)
are false in user build. This prevents a non-A/B device from running
Treble VTS because it requires 'adb root'. Without ALLOW_ADBD_NO_AUTH,
adb still can work if ro.adb.secure = 1. However, allowing it to be 0
is better for test automation.

The image combination in VTS is:
  - system.img (userdebug): provided by Googlg
  - boot.img (user): provided by the OEM  <-- adbd is here
  - vendor.img (user): provided by the OEM

This change allows 'adb root' and 'ro.adb.secure = 0' when the device is
unlocked in user build. No changes for userdebug/eng builds.

Note that the device must be unlocked when running VTS. Otherwise,
verified boot will prevent it from booting the system.img provided by
Google (no verity metadata).

Bug: 63313955
Bug: 63381692
Test: use the above image combination, check 'adb root' and
      'ro.adb.secure = 0' can work

Jerry Zhang 40a8778491 Revert "adb: Lower EP_ALLOC retry count"
This reverts commit 05fe272a87.

Commit "adb: Do not signal gaget stack unless descriptors are written"
fixed the main issue for configfs devices where device wasn't enabled
until after the ioctl was attempted. Thus it is safe to bring up the
retry count so that the ioctl doesn't fail due to small delays in
usb stack.

Test: use adb, switch configs on configfs devices

David Pursell eaae97e127 adb: support forwarding TCP port 0.
This CL adds support to forward or reverse TCP port 0 to allow the
system to automatically select an open port. The resolved port number
will be printed to stdout:
  $ adb forward tcp:0 tcp:8000
  12345
  $ adb reverse tcp:0 tcp:9000
  23456
This allows testing to be more robust by not hardcoding TCP ports which
may already be in use.

Forwarding port 0 is a host-only change and will work with any device,
but reversing port 0 requires the device to be updated with a new adbd
binary.

This CL also does a little bit of cleanup such as moving the alistener
class out of adb.h, and adds some error checking and additional tests.

By using Minijail we avoid writing the same priv-dropping code over

We're already using Minijail for priv-dropping on Brillo.

Minijail is unit- and integration-tested on the
Chrome OS CI infrastructure (pulling from the same repo, see
https://wmatrix.googleplex.com/security?tests=security_Minijail0).
Once CI comes to Android, it will be continuously tested there as well.

Josh Gao 7d58607360 adb: shell: add -n flag to not read from stdin.
Shell scripts of the following form do not work properly with adb:
    echo "foo\nbar\nbaz" | {
        read FOO
        while [ "$FOO" != "" ]; do
            adb shell echo $FOO
            read FOO
        done
    }
The first run of adb shell will consume all of the contents of stdin,
causing the loop to immediately end. ssh solves this by providing a -n
flag that causes it to not read from stdin. This commit adds the same.

Nick Kralevich c39ba5ae32 Enable hidepid=2 on /proc
Add the following mount options to the /proc filesystem:

  hidepid=2,gid=3009

This change blocks /proc access unless you're in group 3009
(aka AID_READPROC).

Please see
  https://github.com/torvalds/linux/blob/master/Documentation/filesystems/proc.txt
for documentation on the hidepid option.

hidepid=2 is preferred over hidepid=1 since it leaks less information
and doesn't generate SELinux ptrace denials when trying to access
/proc without being in the proper group.

Add AID_READPROC to processes which need to access /proc entries for
other UIDs.
