+The system/ directory is intended for pieces of the world that are the

+
+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

+- 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 |
+ | ^^ |

+ ___________________________||_______
+ | || |
+ | 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>
