handle_packet() in adb.c didn't check that when an A_WRTE packet is
received, the sender's local-id matches the socket's peer id.
This meant that a compromised adbd server could sent packets to
the host adb server, spoofing the identity of another connected
device if it could "guess" the right host socket id.
This patch gets rid of the issue by enforcing even more checks
to ensure that all packets comply with the description in
protocol.txt.
+ Fix a bug where closing a local socket associated with a
remote one would always send an A_CLSE(0, remote-id, "")
message, though protocol.txt says that should only happen
for failed opens.
The issue was that local_socket_close() called
remote_socket_close() after clearing the remote socket's
'peer' field.
The fix introduces a new asocket optional callback,
named 'shutdown' that is called before that, and is
used to send the A_CLSE() message with the right ID
in remote_socket_shutdown().
Also add some code in handle_packet() to detect
invalid close commands.

adb connect calls connect() in the event loop. If you pass a wrong ip
address or the server is slow to respond, this will block the event loop
and you can't even kill the adb server with adb kill-server. Handle connect
requests in a service thread instead.

Secure adb using a public key authentication, to allow USB debugging
only from authorized hosts.
When a device is connected to an unauthorized host, the adb daemon sends
the user public key to the device. A popup is shown to ask the user to
allow debugging once or permanantly from the host. The public key is
installed on the device in the later case. Other keys may be installed
at build time.
On the host, the user public/private key pair is automatically generated,
if it does not exist, when the adb daemon starts and is stored in
$HOME/.android/adb_key(.pub) or in $ANDROID_SDK_HOME on windows. If needed,
the ADB_KEYS_PATH env variable may be set to a :-separated (; under
Windows) list of private keys, e.g. company-wide or vendor keys.
On the device, vendors public keys are installed at build time in
/adb_keys. User-installed keys are stored in /data/misc/adb/adb_keys.
ADB Protocol change:
If the device needs to authenticate the host, it replies to CNXN
packets with an AUTH packet. The AUTH packet payload is a random token.
The host signs the token with one of its private keys and sends an AUTH(0)
packet. If the signature verification succeeds, the device replies with
a CNXN packet. Otherwise, it sends a new AUTH packet with a new token so
that the host can retry with another private key. Once the host has tried
all its keys, it can send an AUTH(1) packet with a public key as
payload. adbd then sends the public key to the framework (if it has been
started) for confirmation.

This is the second version of a patch which demonstrates the possibility
of using adbd (Android Debug Bridge daemon) with a generic FunctionFS gadget
instead of a custom adb usb gadget in the Linux kernel. It contains changes
introduced after Benoit's review - thank you Benoit.
The patch adds a new usb access layer to adbd using FunctionFS. The former
usb access method is still available. The method is chosen at runtime
depending if /dev/usb-ffs/adb/ep0 or /dev/android_adb is accessible.
How to use on the target device:
$ insmod g_ffs.ko idVendor=<vendor ID> iSerialNumber=<some string>
$ mount -t functionfs adb /dev/usb-ffs/adb -o uid=2000,gid=2000
$ ./adbd
This patch requires a patch to bionic which adds <linux/usb_functionfs.h>
which is an exact copy of the relevant file in the linux kernel.

adb: Generalizing -s to take qualifiers.

Prior to this change, -s could take either a serial number or a
device path (e.g. "-s 01498B1F02015015" or "-s usb:1-4.2"). This
change extends -s to also allow product, model or device names
(e.g. "-s product:mysid"). These new qualifiers will only be
available on devices that are running an adb daemon that provides
properties in the connect message per Change-Id:
I09200decde4facb8fc9b4056fdae910155f2bcb9
The product, model and device are derived from the
ro.product.name, ro.product.model and ro.product.device
properties respectively. They are prefixed with "product:",
"model:" or "device:" as appropriate. In addition, any
non-alphanumerics in the model are changed to underscores.
If the -s parameter matches multiple devices, the result will be
the same as when multiple devices are connected but no -d, -e or
-s option is specified. In general, this means the user will get
"error: more than one device". However for get-state,
get-devpath and get-serialno, they will get "unknown".
The format of "devices -l" was changed to list all of the
qualifiers that are available. The following example output
(with the last digits of the serial numbers replaced with X's) is
with a Galaxy Prime with an older adb daemon and another Galaxy
Prime and Galaxy S both with the enhanced adb daemons:
List of devices attached
016B75D60A0060XX device usb:2-5 product:mysid model:Galaxy_Nexus device:toro
3731B535FAC200XX device usb:1-4.2 product:soju model:Nexus_S device:crespo
01498B1F020150XX device usb:1-4.1
Note that the serial number and state are now column oriented
instead of tab delimited. After the serial number and state, all
qualifiers are listed with each preceded by a space. The output
of the original devices command (without -l) is unchanged.

adb: Transmit key properties in banner of connect message

protocol.txt says that the connect message should have three
fields:
<systemtype>:<serialno>:<banner>
In reality, what is transmitted is simply:
<systemtype>::
The serialno is obtained via other means so doesn't really need
to be a part of the connect message. This change puts the
ro.product.name, ro.product.model and ro.product.device
properties in the <banner> for devices. Each property is
terminated by a semicolon (;) with the key and value separated by
an equals sign (=). Example message:
device::ro.product.name=<prd>;ro.product.model=<mdl>;ro.product.device=<dev>;
Making this change will enable the device list to provide more
information to the user and to give the potential for being able
to select which device to talk to with the -s option.

adb: Add ability to specify device path

For manufacturing and testing, there is a need to talk to
whatever device is connected to a given port on the host. This
change modifies adb's "-s" option to take either a serial
number or a device path. The device paths of the connected
devices can be listed using "adb devices -l" whose output
will resemble:
List of devices attached
016B75D60A00600D usb:2-5 device
3031D0B2E71D00EC usb:1-4.3 device
The second column lists the device paths. If the -l option is
not given, the output from "adb devices" will be the same as
it used to be (i.e. the paths will not be printed).
The device path can also be obtained with the get-devpath
command:
$adb -s 3031D0B2E71D00EC get-devpath
usb:1-4.3
Note that the format of the device paths are platform dependent.
The example above is from Linux. On OS-X, the paths will be
"usb:" followed by hex digits. For other platforms, the device
paths will be printed as "????????????" and the -s option will
not be able to select a device until someone implements the
underlying functionality.

Services that cause adbd to reboot are currently implemented this way:
write(fd, response)
close(fd)
sleep(1)
exit(1)
sleep(1) is necessary to leave time for the transport to transmit
the response before the daemon exits. This is slow and unreliable.
Instead, add a flag to the asocket to make it exit the daemon only
after the socket is closed.

Recovery will soon support a minimal implementation of adbd which will
do nothing but accept downloads from the "adb sideload" command and
install them. This is the client side command (mostly resurrected out
of the old circa-2007 "adb recover" command) and the new connection
state.

This is needed because the USB driver on the device no longer resets the bus
when exits and restarts.
Since the host side adb no longer detects that adbd has restarted we need
to reset the connection on the host side now.

- adb can now connect to an emulator configured with an arbitrary
pair of <console port, adb port>. These two ports do not have to be
adjacent.
This can be done from the commandline at any time using
adb connect emu:<console_port>,<adb_port>
- Emulators running on ports outside the normal range
(5554/5555-5584/5585) register themselves on startup if they follow
the convention "console port+1==abd port".
- Emulators outside the normal port range will not be auto-detected on
adb startup as these ports are not probed.
- The index into local_transports[] array in transport_local.c does no
longer indicate the port number of the local transport. Use the altered
atransport struct to get the port number.
- I have chosen not to document the adb connect emu:console_port,adb_port
syntax on adb's help screen as this might be confusing to most readers
and useful to very few.
- I don't expect this to introduce any (backwards) compatibility issues.

This is the first CL of a somewhat larger effort which, among other things,
will involve changing the emulator and ddms to talk to adb running on a
configurable port.
The port can be configured using environment variable ANDROID_ADB_SERVER_PORT.

containing the bitmask for adb_trace_mask (see the TRACE_* enum values in adb.h).
This will result in adb writing log output to a file in /data/adb/
No logging will occur if persist.adb.trace_mask is not set or has a value
that cannot be parsed as a hex integer.
The property is read once only at startup, so you must reboot or restart adbd
for changes in the property to take effect.

Vendor IDs are read from ~/.android/adb_usb.ini. The format is very simple:
1 number per line. First number is ID count, followed by the ID themselves.
Lines starting with # are considered comments.
Other misc changes: moved VENDOR_ID_* to usb_vendors.c to prevent direct
access. Made transport_usb.c reuse the USB constant introduced in usb_osx
(moved them to adb.h)

Added usb_vendors.* which handles creating (and deleting) a list of vendor ids.
This list is meant to be used everywhere the built-in lists (usb_osx), or the
built-in vendor IDs (transport_usb) were used.
For now the list is only built with the built-in VENDOR_ID_*. Next step
is to read a small file created from all the SDK add-on.
Other misc changes: made is_adb_interface present only if ADB_HOST is true
to prevent accessing a list that doesn't exist (usb_vendors is only
compiled for the host version of adb).

Enumerating all vendor+product id combinations is not practical.
This modifies the matching algorithm to use the adb interface
subclass/protocol instead (0x42/0x1).
