The system/ directory is intended for pieces of the world that are the
core of the embedded linux platform at the heart of Android. These
essential bits are required for basic booting, operation, and debugging.
They should not depend on libraries outside of system/... (some of them
do currently -- they need to be updated or changed) and they should not
be required for the simulator build.
The license for all these pieces should be clean (Apache2, BSD, or MIT).
Currently system/bluetooth/... and system/extra/... have some pieces
with GPL/LGPL licensed code.
Assorted Issues:
- pppd depends on libutils for logging
- pppd depends on libcrypt/libcrypto
- init, linker, debuggerd, toolbox, usbd depend on libcutils
- should probably rename bionic to libc

Implementation notes regarding ADB.
I. General Overview:
The Android Debug Bridge (ADB) is used to:
- keep track of all Android devices and emulators instances
connected to or running on a given host developer machine
- implement various control commands (e.g. "adb shell", "adb pull", etc..)
for the benefit of clients (command-line users, or helper programs like
DDMS). These commands are what is called a 'service' in ADB.
As a whole, everything works through the following components:
1. The ADB server
This is a background process that runs on the host machine. Its purpose
if to sense the USB ports to know when devices are attached/removed,
as well as when emulator instances start/stop.
It thus maintains a list of "connected devices" and assigns a 'state'
to each one of them: OFFLINE, BOOTLOADER, RECOVERY or ONLINE (more on
this below).
The ADB server is really one giant multiplexing loop whose purpose is
to orchestrate the exchange of data (packets, really) between clients,
services and devices.
2. The ADB daemon (adbd)
The 'adbd' program runs as a background process within an Android device
or emulated system. Its purpose is to connect to the ADB server
(through USB for devices, through TCP for emulators) and provide a
few services for clients that run on the host.
The ADB server considers that a device is ONLINE when it has succesfully
connected to the adbd program within it. Otherwise, the device is OFFLINE,
meaning that the ADB server detected a new device/emulator, but could not
connect to the adbd daemon.
the BOOTLOADER and RECOVERY states correspond to alternate states of
devices when they are in the bootloader or recovery mode.
3. The ADB command-line client
The 'adb' command-line program is used to run adb commands from a shell
or a script. It first tries to locate the ADB server on the host machine,
and will start one automatically if none is found.
then, the client sends its service requests to the ADB server. It doesn't
need to know.
Currently, a single 'adb' binary is used for both the server and client.
this makes distribution and starting the server easier.
4. Services
There are essentially two kinds of services that a client can talk to.
Host Services:
these services run within the ADB Server and thus do not need to
communicate with a device at all. A typical example is "adb devices"
which is used to return the list of currently known devices and their
state. They are a few couple other services though.
Local Services:
these services either run within the adbd daemon, or are started by
it on the device. The ADB server is used to multiplex streams
between the client and the service running in adbd. In this case
its role is to initiate the connection, then of being a pass-through
for the data.
II. Protocol details:
1. Client <-> Server protocol:
This details the protocol used between ADB clients and the ADB
server itself. The ADB server listens on TCP:localhost:5037.
A client sends a request using the following format:
1. A 4-byte hexadecimal string giving the length of the payload
2. Followed by the payload itself.
For example, to query the ADB server for its internal version number,
the client will do the following:
1. Connect to tcp:localhost:5037
2. Send the string "000Chost:version" to the corresponding socket
The 'host:' prefix is used to indicate that the request is addressed
to the server itself (we will talk about other kinds of requests later).
The content length is encoded in ASCII for easier debugging.
The server should answer a request with one of the following:
1. For success, the 4-byte "OKAY" string
2. For failure, the 4-byte "FAIL" string, followed by a
4-byte hex length, followed by a string giving the reason
for failure.
3. As a special exception, for 'host:version', a 4-byte
hex string corresponding to the server's internal version number
Note that the connection is still alive after an OKAY, which allows the
client to make other requests. But in certain cases, an OKAY will even
change the state of the connection.
For example, the case of the 'host:transport:<serialnumber>' request,
where '<serialnumber>' is used to identify a given device/emulator; after
the "OKAY" answer, all further requests made by the client will go
directly to the corresponding adbd daemon.
The file SERVICES.TXT lists all services currently implemented by ADB.
2. Transports:
An ADB transport models a connection between the ADB server and one device
or emulator. There are currently two kinds of transports:
- USB transports, for physical devices through USB
- Local transports, for emulators running on the host, connected to
the server through TCP
In theory, it should be possible to write a local transport that proxies
a connection between an ADB server and a device/emulator connected to/
running on another machine. This hasn't been done yet though.
Each transport can carry one or more multiplexed streams between clients
and the device/emulator they point to. The ADB server must handle
unexpected transport disconnections (e.g. when a device is physically
unplugged) properly.

This file tries to document all requests a client can make
to the ADB server of an adbd daemon. See the OVERVIEW.TXT document
to understand what's going on here.
HOST SERVICES:
host:version
Ask the ADB server for its internal version number.
As a special exception, the server will respond with a 4-byte
hex string corresponding to its internal version number, without
any OKAY or FAIL.
host:kill
Ask the ADB server to quit immediately. This is used when the
ADB client detects that an obsolete server is running after an
upgrade.
host:devices
Ask to return the list of available Android devices and their
state. After the OKAY, this is followed by a 4-byte hex len,
and a string that will be dumped as-is by the client, then
the connection is closed
host:track-devices
This is a variant of host:devices which doesn't close the
connection. Instead, a new device list description is sent
each time a device is added/removed or the state of a given
device changes (hex4 + content). This allows tools like DDMS
to track the state of connected devices in real-time without
polling the server repeatedly.
host:emulator:<port>
This is a special query that is sent to the ADB server when a
new emulator starts up. <port> is a decimal number corresponding
to the emulator's ADB control port, i.e. the TCP port that the
emulator will forward automatically to the adbd daemon running
in the emulator system.
This mechanism allows the ADB server to know when new emulator
instances start.
host:transport:<serial-number>
Ask to switch the connection to the device/emulator identified by
<serial-number>. After the OKAY response, every client request will
be sent directly to the adbd daemon running on the device.
(Used to implement the -s option)
host:transport-usb
Ask to switch the connection to one device connected through USB
to the host machine. This will fail if there are more than one such
devices. (Used to implement the -d convenience option)
host:transport-local
Ask to switch the connection to one emulator connected through TCP.
This will fail if there is more than one such emulator instance
running. (Used to implement the -e convenience option)
host:transport-any
Another host:transport variant. Ask to switch the connection to
either the device or emulator connect to/running on the host.
Will fail if there is more than one such device/emulator available.
(Used when neither -s, -d or -e are provided)
host-serial:<serial-number>:<request>
This is a special form of query, where the 'host-serial:<serial-number>:'
prefix can be used to indicate that the client is asking the ADB server
for information related to a specific device. <request> can be in one
of the format described below.
host-usb:<request>
A variant of host-serial used to target the single USB device connected
to the host. This will fail if there is none or more than one.
host-local:<request>
A variant of host-serial used to target the single emulator instance
running on the host. This will fail if therre is none or more than one.
host:<request>
When asking for information related to a device, 'host:' can also be
interpreted as 'any single device or emulator connected to/running on
the host'.
<host-prefix>:get-product
XXX
<host-prefix>:get-serialno
Returns the serial number of the corresponding device/emulator.
Note that emulator serial numbers are of the form "emulator-5554"
<host-prefix>:get-state
Returns the state of a given device as a string.
<host-prefix>:forward:<local>;<remote>
Asks the ADB server to forward local connections from <local>
to the <remote> address on a given device.
There, <host-prefix> can be one of the
host-serial/host-usb/host-local/host prefixes as described previously
and indicates which device/emulator to target.
the format of <local> is one of:
tcp:<port> -> TCP connection on localhost:<port>
local:<path> -> Unix local domain socket on <path>
the format of <remote> is one of:
tcp:<port> -> TCP localhost:<port> on device
local:<path> -> Unix local domain socket on device
jdwp:<pid> -> JDWP thread on VM process <pid>
or even any one of the local services described below.
LOCAL SERVICES:
All the queries below assumed that you already switched the transport
to a real device, or that you have used a query prefix as described
above.
shell:command arg1 arg2 ...
Run 'command arg1 arg2 ...' in a shell on the device, and return
its output and error streams. Note that arguments must be separated
by spaces. If an argument contains a space, it must be quoted with
double-quotes. Arguments cannot contain double quotes or things
will go very wrong.
Note that this is the non-interactive version of "adb shell"
shell:
Start an interactive shell session on the device. Redirect
stdin/stdout/stderr as appropriate. Note that the ADB server uses
this to implement "adb shell", but will also cook the input before
sending it to the device (see interactive_shell() in commandline.c)
remount:
Ask adbd to remount the device's filesystem in read-write mode,
instead of read-only. This is usually necessary before performing
an "adb sync" or "adb push" request.
This request may not succeed on certain builds which do not allow
that.
dev:<path>
Opens a device file and connects the client directly to it for
read/write purposes. Useful for debugging, but may require special
priviledges and thus may not run on all devices. <path> is a full
path from the root of the filesystem.
tcp:<port>
Tries to connect to tcp port <port> on localhost.
tcp:<port>:<server-name>
Tries to connect to tcp port <port> on machine <server-name> from
the device. This can be useful to debug some networking/proxy
issues that can only be revealed on the device itself.
local:<path>
Tries to connect to a Unix domain socket <path> on the device
localreserved:<path>
localabstract:<path>
localfilesystem:<path>
Variants of local:<path> that are used to access other Android
socket namespaces.
log:<name>
Opens one of the system logs (/dev/log/<name>) and allows the client
to read them directly. Used to implement 'adb logcat'. The stream
will be read-only for the client.
framebuffer:
This service is used to send snapshots of the framebuffer to a client.
It requires sufficient priviledges but works as follow:
After the OKAY, the service sends 16-byte binary structure
containing the following fields (little-endian format):
depth: uint32_t: framebuffer depth
size: uint32_t: framebuffer size in bytes
width: uint32_t: framebuffer width in pixels
height: uint32_t: framebuffer height in pixels
With the current implementation, depth is always 16, and
size is always width*height*2
Then, each time the client wants a snapshot, it should send
one byte through the channel, which will trigger the service
to send it 'size' bytes of framebuffer data.
If the adbd daemon doesn't have sufficient priviledges to open
the framebuffer device, the connection is simply closed immediately.
dns:<server-name>
This service is an exception because it only runs within the ADB server.
It is used to implement USB networking, i.e. to provide a network connection
to the device through the host machine (note: this is the exact opposite of
network thetering).
It is used to perform a gethostbyname(<address>) on the host and return
the corresponding IP address as a 4-byte string.
recover:<size>
This service is used to upload a recovery image to the device. <size>
must be a number corresponding to the size of the file. The service works
by:
- creating a file named /tmp/update
- reading 'size' bytes from the client and writing them to /tmp/update
- when everything is read succesfully, create a file named /tmp/update.start
This service can only work when the device is in recovery mode. Otherwise,
the /tmp directory doesn't exist and the connection will be closed immediately.
jdwp:<pid>
Connects to the JDWP thread running in the VM of process <pid>.
track-jdwp
This is used to send the list of JDWP pids periodically to the client.
The format of the returned data is the following:
<hex4>: the length of all content as a 4-char hexadecimal string
<content>: a series of ASCII lines of the following format:
<pid> "\n"
This service is used by DDMS to know which debuggable processes are running
on the device/emulator.
Note that there is no single-shot service to retrieve the list only once.
sync:
This starts the file synchronisation service, used to implement "adb push"
and "adb pull". Since this service is pretty complex, it will be detailed
in a companion document named SYNC.TXT

/* here's how these things work.
when adbd starts, it creates a unix server socket
named @vm-debug-control (@ is a shortcut for "first byte is zero"
to use the private namespace instead of the file system)
when a new JDWP daemon thread starts in a new VM process, it creates
a connection to @vm-debug-control to announce its availability.
JDWP thread @vm-debug-control
| |
|-------------------------------> |
| hello I'm in process <pid> |
| |
| |
the connection is kept alive. it will be closed automatically if
the JDWP process terminates (this allows adbd to detect dead
processes).
adbd thus maintains a list of "active" JDWP processes. it can send
its content to clients through the "device:debug-ports" service,
or even updates through the "device:track-debug-ports" service.
when a debugger wants to connect, it simply runs the command
equivalent to "adb forward tcp:<hostport> jdwp:<pid>"
"jdwp:<pid>" is a new forward destination format used to target
a given JDWP process on the device. when sutch a request arrives,
adbd does the following:
- first, it calls socketpair() to create a pair of equivalent
sockets.
- it attaches the first socket in the pair to a local socket
which is itself attached to the transport's remote socket:
- it sends the file descriptor of the second socket directly
to the JDWP process with the help of sendmsg()
JDWP thread @vm-debug-control
| |
| <----------------------|
| OK, try this file descriptor |
| |
| |
then, the JDWP thread uses this new socket descriptor as its
pass-through connection to the debugger (and receives the
JDWP-Handshake message, answers to it, etc...)
this gives the following graphics:
____________________________________
| |
| ADB Server (host) |
| |
Debugger <---> LocalSocket <----> RemoteSocket |
| ^^ |
|___________________________||_______|
||
Transport ||
(TCP for emulator - USB for device) ||
||
___________________________||_______
| || |
| ADBD (device) || |
| VV |
JDWP <======> LocalSocket <----> RemoteSocket |
| |
|____________________________________|
due to the way adb works, this doesn't need a special socket
type or fancy handling of socket termination if either the debugger
or the JDWP process closes the connection.
THIS IS THE SIMPLEST IMPLEMENTATION I COULD FIND, IF YOU HAPPEN
TO HAVE A BETTER IDEA, LET ME KNOW - Digit

--- a replacement for aproto -------------------------------------------
When it comes down to it, aproto's primary purpose is to forward
various streams between the host computer and client device (in either
direction).
This replacement further simplifies the concept, reducing the protocol
to an extremely straightforward model optimized to accomplish the
forwarding of these streams and removing additional state or
complexity.
The host side becomes a simple comms bridge with no "UI", which will
be used by either commandline or interactive tools to communicate with
a device or emulator that is connected to the bridge.
The protocol is designed to be straightforward and well-defined enough
that if it needs to be reimplemented in another environment (Java
perhaps), there should not problems ensuring perfect interoperability.
The protocol discards the layering aproto has and should allow the
implementation to be much more robust.
--- protocol overview and basics ---------------------------------------
The transport layer deals in "messages", which consist of a 24 byte
header followed (optionally) by a payload. The header consists of 6
32 bit words which are sent across the wire in little endian format.
struct message {
unsigned command; /* command identifier constant */
unsigned arg0; /* first argument */
unsigned arg1; /* second argument */
unsigned data_length; /* length of payload (0 is allowed) */
unsigned data_crc32; /* crc32 of data payload */
unsigned magic; /* command ^ 0xffffffff */
};
Receipt of an invalid message header, corrupt message payload, or an
unrecognized command MUST result in the closing of the remote
connection. The protocol depends on shared state and any break in the
message stream will result in state getting out of sync.
The following sections describe the six defined message types in
detail. Their format is COMMAND(arg0, arg1, payload) where the payload
is represented by a quoted string or an empty string if none should be
sent.
The identifiers "local-id" and "remote-id" are always relative to the
*sender* of the message, so for a receiver, the meanings are effectively
reversed.
--- CONNECT(version, maxdata, "system-identity-string") ----------------
The CONNECT message establishes the presence of a remote system.
The version is used to ensure protocol compatibility and maxdata
declares the maximum message body size that the remote system
is willing to accept.
Currently, version=0x01000000 and maxdata=4096
Both sides send a CONNECT message when the connection between them is
established. Until a CONNECT message is received no other messages may
be sent. Any messages received before a CONNECT message MUST be ignored.
If a CONNECT message is received with an unknown version or insufficiently
large maxdata value, the connection with the other side must be closed.
The system identity string should be "<systemtype>:<serialno>:<banner>"
where systemtype is "bootloader", "device", or "host", serialno is some
kind of unique ID (or empty), and banner is a human-readable version
or identifier string (informational only).
--- OPEN(local-id, 0, "destination") -----------------------------------
The OPEN message informs the recipient that the sender has a stream
identified by local-id that it wishes to connect to the named
destination in the message payload. The local-id may not be zero.
The OPEN message MUST result in either a READY message indicating that
the connection has been established (and identifying the other end) or
a CLOSE message, indicating failure. An OPEN message also implies
a READY message sent at the same time.
Common destination naming conventions include:
* "tcp:<host>:<port>" - host may be omitted to indicate localhost
* "udp:<host>:<port>" - host may be omitted to indicate localhost
* "local-dgram:<identifier>"
* "local-stream:<identifier>"
* "shell" - local shell service
* "upload" - service for pushing files across (like aproto's /sync)
* "fs-bridge" - FUSE protocol filesystem bridge
--- READY(local-id, remote-id, "") -------------------------------------
The READY message informs the recipient that the sender's stream
identified by local-id is ready for write messages and that it is
connected to the recipient's stream identified by remote-id.
Neither the local-id nor the remote-id may be zero.
A READY message containing a remote-id which does not map to an open
stream on the recipient's side is ignored. The stream may have been
closed while this message was in-flight.
The local-id is ignored on all but the first READY message (where it
is used to establish the connection). Nonetheless, the local-id MUST
not change on later READY messages sent to the same stream.
--- WRITE(0, remote-id, "data") ----------------------------------------
The WRITE message sends data to the recipient's stream identified by
remote-id. The payload MUST be <= maxdata in length.
A WRITE message containing a remote-id which does not map to an open
stream on the recipient's side is ignored. The stream may have been
closed while this message was in-flight.
A WRITE message may not be sent until a READY message is received.
Once a WRITE message is sent, an additional WRITE message may not be
sent until another READY message has been received. Recipients of
a WRITE message that is in violation of this requirement will CLOSE
the connection.
--- CLOSE(local-id, remote-id, "") -------------------------------------
The CLOSE message informs recipient that the connection between the
sender's stream (local-id) and the recipient's stream (remote-id) is
broken. The remote-id MUST not be zero, but the local-id MAY be zero
if this CLOSE indicates a failed OPEN.
A CLOSE message containing a remote-id which does not map to an open
stream on the recipient's side is ignored. The stream may have
already been closed by the recipient while this message was in-flight.
The recipient should not respond to a CLOSE message in any way. The
recipient should cancel pending WRITEs or CLOSEs, but this is not a
requirement, since they will be ignored.
--- SYNC(online, sequence, "") -----------------------------------------
The SYNC message is used by the io pump to make sure that stale
outbound messages are discarded when the connection to the remote side
is broken. It is only used internally to the bridge and never valid
to send across the wire.
* when the connection to the remote side goes offline, the io pump
sends a SYNC(0, 0) and starts discarding all messages
* when the connection to the remote side is established, the io pump
sends a SYNC(1, token) and continues to discard messages
* when the io pump receives a matching SYNC(1, token), it once again
starts accepting messages to forward to the remote side
--- message command constants ------------------------------------------
#define A_SYNC 0x434e5953
#define A_CNXN 0x4e584e43
#define A_OPEN 0x4e45504f
#define A_OKAY 0x59414b4f
#define A_CLSE 0x45534c43
#define A_WRTE 0x45545257
--- implementation details ---------------------------------------------
The core of the bridge program will use three threads. One thread
will be a select/epoll loop to handle io between various inbound and
outbound connections and the connection to the remote side.
The remote side connection will be implemented as two threads (one for
reading, one for writing) and a datagram socketpair to provide the
channel between the main select/epoll thread and the remote connection
threadpair. The reason for this is that for usb connections, the
kernel interface on linux and osx does not allow you to do meaningful
nonblocking IO.
The endian swapping for the message headers will happen (as needed) in
the remote connection threadpair and that the rest of the program will
always treat message header values as native-endian.
The bridge program will be able to have a number of mini-servers
compiled in. They will be published under known names (examples
"shell", "fs-bridge", etc) and upon receiving an OPEN() to such a
service, the bridge program will create a stream socketpair and spawn
a thread or subprocess to handle the io.
--- simplified / embedded implementation -------------------------------
For limited environments, like the bootloader, it is allowable to
support a smaller, fixed number of channels using pre-assigned channel
ID numbers such that only one stream may be connected to a bootloader
endpoint at any given time. The protocol remains unchanged, but the
"embedded" version of it is less dynamic.
The bootloader will support two streams. A "bootloader:debug" stream,
which may be opened to get debug messages from the bootloader and a
"bootloader:control", stream which will support the set of basic
bootloader commands.
Example command stream dialogues:
"flash_kernel,2515049,........\n" "okay\n"
"flash_ramdisk,5038,........\n" "fail,flash write error\n"
"bogus_command......" <CLOSE>
--- future expansion ---------------------------------------------------
I plan on providing either a message or a special control stream so that
the client device could ask the host computer to setup inbound socket
translations on the fly on behalf of the client device.
The initial design does handshaking to provide flow control, with a
message flow that looks like:
>OPEN <READY >WRITE <READY >WRITE <READY >WRITE <CLOSE
The far side may choose to issue the READY message as soon as it receives
a WRITE or it may defer the READY until the write to the local stream
succeeds. A future version may want to do some level of windowing where
multiple WRITEs may be sent without requiring individual READY acks.
------------------------------------------------------------------------
--- smartsockets -------------------------------------------------------
Port 5037 is used for smart sockets which allow a client on the host
side to request access to a service in the host adb daemon or in the
remote (device) daemon. The service is requested by ascii name,
preceeded by a 4 digit hex length. Upon successful connection an
"OKAY" response is sent, otherwise a "FAIL" message is returned. Once
connected the client is talking to that (remote or local) service.
client: <hex4> <service-name>
server: "OKAY"
client: <hex4> <service-name>
server: "FAIL" <hex4> <reason>
