d51c6df1ef adb: stop using quick_exit.
We don't actually need to use quick_exit to avoid calling static
destructors, since we have -Wexit-time-destructors to guarantee we
don't actually have any, and this precludes the use of asan's exit time
leak checking, so switch back to atexit/exit.

Test: ASAN_OPTIONS=detect_leaks=1:leak_check_at_exit=1 adb server nodaemon with a manually inserted leak

9425996b45 adb: get libusb compiling on Windows.
This still doesn't work yet because libusb doesn't support hotplug on
Windows yet, but it's in the milestones for the next libusb release,
and this is enough to start poking around with the WinUSB device-side
stuff, so leave it broken for now.

e48ecce671 Revert "adb: fix deadlock between transport_unref and usb_close."
This reverts commit 7e197ef833.

The mutex lock in transport_unref hides a race that seems otherwise
hard to fix. Specifically, there's no synchronization between acquiring
a transport and attaching it to an asocket*, leading to badness if the
transport is closed in between the two operations.

Fix the original problem the reverted patch addressed by manually
unlocking before calling unregister_usb_transport.

reusing the main thread for this, since the main thread blocks until
device scan is complete.

can access it, before trying to open it.

ef3d343254 adb: use the actual wMaxPacketSize for usb endpoints.
Previously, adb was assuming a fixed maximum packet size of 1024 bytes
(the value for an endpoint connected via USB 3.0). When connected to an
endpoint that has an actual maximum packet size of 512 bytes (i.e.
every single device over USB 2.0), the following could occur:

    device sends amessage with 512 byte payload
    client reads amessage
    client tries to read payload with a length of 1024

In this scenario, the kernel will block, waiting for an additional
packet which won't arrive until something else gets sent across the
wire, which will result in the previous read failing, and the new
packet being dropped.

b5e11415d9 adb: fix two device offline problems.
When device goes offline, user usually has to manually replug the
usb device. This patch tries to solve two offline situations, all
because when adb on host is killed, the adbd on device is not notified.

1. When adb server is killed while pushing a large file to device,
the device is still reading the unfinished large message. So the
device thinks of the CNXN message as part of the previous unfinished
message, so it doesn't reply and the device is in offline state.

The solution is to add a write_msg_lock in atransport struct. And it
kicks the transport only after sending a whole message. By kicking
all transports before exit, we ensure that we don't write part of
a message to any device. So next time we start adb server, the device
should be waiting for a new message.

2. When adb server is killed while pulling a large file from device,
the device is still trying to send the unfinished large message. So
adb on host usually reads data with EOVERFLOW error. This is because
adb on host is reading less than one packet sent from device.

The solution is to use buffered read on host. The max packet size
of bulk transactions in USB 3.0 is 1024 bytes. By preparing an at least
1024 bytes buffer when reading, EOVERFLOW no longer occurs. And teach
adb host to ignore wrong messages.

To be safe, this patch doesn't change any logic on device.

0aeb50500c Clean up key handling in adb.
This includes the locking we need to be able to re-load the keys at runtime.

We should rename "adb_auth_client.cpp" to "adb_auth_adbd.cpp" or
"adbd_auth.cpp" in a later change.

d89a6c2285 Allow multiple (sequential) adb users on Linux.
Before this, adb will fail to start for the second user who tries because
/tmp/adb.log already exists and isn't writable by the second user.

Also allow $TMPDIR to override the use of /tmp.

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.

Bug: 28051746
Test: python -m unittest discover
Test: adb_test
Test: `adb forward` and `adb reverse` with tcp:0

6bf323b97a adb: setsid() for adb host server.
To create a daemon for adb host server, we should call setsid()
for the daemon process. However, previously we call setsid() for
the adb client process, which results in nothing but EPERM error.

b72b3f8c92 adb: make ctrl-c when spawning a daemon not kill the daemon.
Previously, using ctrl-c in a command that needs to spawn a daemon
because one isn't already available would kill the daemon along with the
foreground process.
