Yabin Cui 7a3f8d6691 adb: clean up debug tracing a little.
Always use LOG() for debug tracing.
Remove useless D_lock. I believe it is useless to lock just before and after fprintf.

I verified the log output both on host and on device. The output looks fine to me.

Yabin Cui f4b9928563 adb: disconnect: fix write-after-free memory corruption and crash.
Transport atransport objects are semi-reference counted: the input and
output threads each hold a reference. The adb disconnect command was
calling transport_unref to release a reference that it never had in the
first place. This meant that the refcount dropped to zero and the object
was deleted before either the input or output thread released its
reference. When that last thread released its reference, it wrote to
freed memory and also sometimes crashed.

This fix is to not release any unheld reference, instead it just kicks
the transport to break remote_read in output_thread. So all transport
close flow goes the following way:
output_thread (exit) -> main thread (offline the transport) ->
input thread (exit) -> main thread (destroy the transport)

Spencer Low 2122c7a148 win32: adb start-server shows stdout/stderr output from actual server
When launching the adb server (typically from adb start-server),
redirect stdout/stderr to anonymous pipes which are read by threads in
the parent process, to make error diagnosis easier.

If there is an error during adb start-server, the output looks like:

> adb start-server
* daemon not running. starting it now on port 5037 *
error: could not blah                 # from server process
could not read ok from ADB Server     # from launch_server
* failed to start daemon *            # from adb_connect
error: cannot connect to daemon       # from adb_commandline

Fix handle-leaks in launch_server by using new unique_handle class
that is based on std::unique_ptr.

In the server, close stdin and redirect to adb.log *before* sending the
ACK, so that any errors are reported early instead of after the ACK.

Yabin Cui 34f45c5663 adb: keep all asocket operations in the main thread.
As far as I can see, all asockets operations happen in fdevent_loop()
in the main thread, excepting close_all_sockets(). Instead of adding
lock and ref_count for each asocket, a simpler way would be moving
close_all_sockets() from input_thread to the main thread.

In input_thread(), there are two path to break the loop and call
close_all_sockets(). One path is when receiving offline A_SYNC, which
is sent by the main thread. The other path is when read_packet
fails, which I believe is almost not possible and doesn't matter
(Because t->fd is closed just before t is freed.). So I move
close_all_sockets() to handle_offline() in the main thread.

the socket_list_lock in sockets.cpp could be removed. But I prefer
to leave it for the following changes.

    this will ever get hit).

Spencer Low bf7c605d87 adb: improve network error info
- handle_forward_request
  - Because we have detailed info about which syscall failed (at least
    on Win32), use a more generic prefix of "cannot bind listener" followed
    by the detailed info.

- install_listener
  - Return string errors for a few errors even though I don't think any
    callers actually output the string for those errors.

  - Remove the printf since the callers print the message themselves.

- adb_main
  - LOG(FATAL) calls abort() which on Windows calls the Windows Error
    Reporting service which pops up a dialog asking if you want a
    crashdump to be uploaded to Microsoft. So really, abort() is
    designed for app bugs. Windows isn't the only one doing this, Chromium
    also makes LOG(FATAL) crashdump-ready. Since an error here is not
    necessarily an app-bug, use a 'normal' error output API like fatal()
    which prints an error and just uses exit().

- sysdeps_win32.cpp
  - When Winsock APIs fail, make the string clarify which API failed.
    Use terse unix-style descriptions (like what you'd get from
    cp/mv/dd/etc.).

  - Don't trace WSAEWOULDBLOCK from recv() which is a normal occurrence.

  - Add a comment about WSAEWOULDBLOCK => EAGAIN.

Spencer Low 7430916098 adb: call android::base::InitLogging even when adb tracing is disabled
This is a follow-up to https://android-review.googlesource.com/153623
which prevented android::base::InitLogging() from being called when
tracing was disabled.

It is ok to call InitLogging() on a device or host because calling it
does not imply that a logging file is used, which was the reason for
not calling it on a device.

So this change should preserve the device behavior of not using a
logging file when tracing is disabled, plus it will call InitLogging()
all the time in case logging APIs are called.

Yabin Cui 661327e8e4 Remove confusing variable HOST.
First, HOST is always 0 in adbd, which matches ADB_HOST=0.
Second, HOST is always 1 when adb_main is called, which matches ADB_HOST=1.
For adb client that doesn't call adb_main, it never touches local_init(),
init_transport_registration() and fdevent_loop(). So the changes in adb.cpp,
services.cpp and transport_local.cpp do nothing with it.
As a conclusion, I think we can remove HOST and use ADB_HOST instead.

erroneously returning an error when --reply-fd was not used, which
should not be necessary for this particular command.

Siva Velusamy 9f2d1a9cfc adb start-server: Use a separate fd for sending initial OK
When "adb start-server" is issued, and a server needs to be launched,
adb client forks itself and the child process runs the server routine.
Once the server initializes its various components, it sends an "OK\n"
back to the client via its stderror (or stdout on Windows).

This sequence breaks down if before sending the "OK\n", the server
happens to log something on its stderr. In order to avoid this, the
client now expects the ack to come on a different fd rather than one
of the standard streams.

Spencer Low cf4ff64f2d adb: win32: Unicode path names, env vars, some console support
Initial support for Unicode file/dir names. Unicode paths can be passed
on the command line, directory enumeration can enumerate Unicode paths,
Unicode paths are used for file access, and Unicode paths can be output
on the console correctly.

Also Unicode environment variable access.

Initial support for Unicode output from adb shell (which uses
adb_fwrite()). This is partial because the corner case of an
adb_fwrite() call with an incomplete UTF-8 multi-byte sequence does not
output correctly, but this should be uncommon, is better than what we
had before (*always* incorrect UTF-8 multi-byte sequences) and can be
fixed in the future.

Calls to Windows APIs with char strings were changed to pass wchar_t
strings to the FooW() variants.

For more details, see the giant comment in sysdeps_win32.cpp.

Spencer Low 5200c6670f adb: win32: initial IPv6 support and improved Winsock error reporting
Call getaddrinfo() for connecting to IPv6 destinations.

Winsock APIs do not set errno. WSAGetLastError() returns Winsock errors
that are more numerous than BSD sockets, so it really doesn't make sense
to map those to BSD socket errors. Plus, even if we did that, the
Windows C Runtime (that mingw binaries use) has a strerror() that does
not recognize BSD socket error codes.

The solution is to wrap the various libcutils socket_* APIs with
sysdeps.h network_* APIs. For POSIX, the network_* APIs just call
strerror(). For Windows, they call SystemErrorCodeToString() (adapted
from Chromium).

Also in this change:

 - Various other code was modified to return errors in a std::string*
   argument, to be able to surface the error string to the end-user.

 - Improved error checking and use of D() to log Winsock errors for
   improved debuggability.

 - For sysdeps_win32.cpp, added unique_fh class that works like
   std::unique_ptr, for calling _fh_close().

 - Fix win32 adb_socketpair() setting of errno in error case.

 - Improve _socket_set_errno() D() logging to reduce confusion. Map
   a few extra error codes.

 - Move adb_shutdown() lower in sysdeps_win32.cpp so it can call
   _socket_set_errno().

 - Move network_connect() from adb_utils.cpp to sysdeps.h.

 - Merge socket_loopback_server() and socket_inaddr_any_server() into
   _network_server() since most of the code was identical.

Tamas Berghammer 3d2904cdf2 Increase size of the the adb packets sent over the wire
The reason behing this change is to increase the adb push/pull speed
with reduceing the number of packets sent between the host and the
device because the communication is heavily bound by packet latency.

The change maintains two way compatibility in the communication
protocol with negotiating a packet size between the target and the
host with the CONNECT packets.

After this change the push/pull speeds improved significantly
(measured from Linux-x86_64 with 100MB of data):

Add missing \n to uses of legacy D() macro. This should make the legacy
logging easier to read (and harder to miss important stuff).

On POSIX, use gettid() from libcutils instead of pthread_self() so that

This should be ok since libbase's logging already uses gettid().

Don't let the Win32 last error get overwritten by API calls after the
original error'ing API. When encountering an unknown error, log the

Any output from the LOG family will now go to stderr and logcat on the
device. stderr is usually redirected to a log file, but that is now
inhibited for adbd if being run from a tty (useful when debugging with
the serial console).

This also fixes sending logs to the file on device for the trace mask
of "all". The "all" tag was specifically handled to return early from
the function, preventing the file initialization from happening.

Elliott Hughes 7be29c819b Show $ADB_VENDOR_KEYS if authentication fails.
Incorrectly set $ADB_VENDOR_KEYS is the most likely cause of failed
adb connections. Make it easier to debug such problems by including
the value in use in the error message.

Dan Albert 8743ef9841 Additional cleanup of start_device_log.
Addresses nnk's post commit review comments on
https://android-review.googlesource.com/#/c/139381/

Remove unneeded code for creating /data/adb.

Add an O_CLOEXEC.

Move the closing of stdin out to main().

Append the pid of the current process to the log file to avoid
clobbering the log if the process crashes and restarts within the same
second.

Dan Albert ea2175ab6b Use text based trace masks for adbd.
Previously the adbd trace mask had to be set as raw hex rather than
with the colon separated list. We all have better things to do than
memorize bitmasks, so make adbd use the same trace mask setting code
as adb.
