-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

+    This implements the 'adb reverse' feature, i.e. the ability to reverse

+      forward:norebind:<local>;<remote>
+      killforward-all

+    and <remote> corresponds to the socket on the host.
+
+    The output of reverse:list-forward is the same as host:list-forward
+    except that <serial> will be just 'host'.

+This file tries to document file related 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. See the SERVICES.TXT to learn more
+about the other requests that are possible.
+
+SYNC SERVICES:
+
+
+Requesting the sync service ("sync:") using the protocol as described in
+SERVICES.TXT sets the connection in sync mode. This mode is a binary mode that
+differ from the regular adb protocol. The connection stays in sync mode until
+explicitly terminated (see below).
+
+After the initial "sync:" command is sent the server must respond with either
+"OKAY" or "FAIL" as per usual. 
+
+In sync mode both the server and the client will frequently use eight-byte
+packets to communicate in this document called sync request and sync
+responses. The first four bytes is an id and specifies sync request is
+represented by four utf-8 characters. The last four bytes is a Little-Endian
+integer, with various uses. This number will be called "length" below. In fact
+all binary integers are Little-Endian in the sync mode. Sync mode is
+implicitly exited after each sync request, and normal adb communication
+follows as described in SERVICES.TXT.
+
+The following sync requests are accepted:
+LIST - List the files in a folder
+SEND - Send a file to device
+RECV - Retreive a file from device
+
+Not yet documented:
+STAT - Stat a file
+ULNK - Unlink (remove) a file. (Not currently supported)
+
+For all of the sync request above the must be followed by length number of
+bytes containing an utf-8 string with a remote filename.
+
+LIST:
+Lists files in the directory specified by the remote filename. The server will
+respond with zero or more directory entries or "dents".
+
+The directory entries will be returned in the following form
+1. A four-byte sync response id beeing "DENT"
+2. A four-byte integer representing file mode.
+3. A four-byte integer representing file size.
+4. A four-byte integer representing last modified time.
+5. A four-byte integer representing file name length.
+6. length number of bytes containing an utf-8 string representing the file
+   name.
+
+When an sync response "DONE" is received the listing is done.
+
+SEND:
+The remote file name is split into two parts separated by the last
+comma (","). The first part is the actual path, while the second is a decimal
+encoded file mode containing the permissions of the file on device.
+
+Note that some file types will be deleted before the copying starts, and if
+the transfer fails. Some file types will not be deleted, which allows
+  adb push disk_image /some_block_device
+to work.
+
+After this the actual file is sent in chunks. Each chucks has the following
+format.
+A sync request with id "DATA" and length equal to the chunk size. After
+follows chunk size number of bytes. This is repeated until the file is
+transfered. Each chunk must not be larger than 64k.
+
+When the file is tranfered a sync request "DONE" is sent, where length is set
+to the last modified time for the file. The server responds to this last
+request (but not to chuck requests) with an "OKAY" sync response (length can
+be ignored).
+
+
+RECV:
+Retrieves a file from device to a local file. The remote path is the path to
+the file that will be returned. Just as for the SEND sync request the file
+received is split up into chunks. The sync response id is "DATA" and length is
+the chuck size. After follows chunk size number of bytes. This is repeated
+until the file is transfered. Each chuck will not be larger than 64k.
+
+When the file is transfered a sync resopnse "DONE" is retrieved where the
+length can be ignored.

+//
+// One caveat is that arraysize() doesn't accept any array of an
+// anonymous type or a type defined inside a function.  In these rare
+// cases, you have to use the unsafe ARRAYSIZE_UNSAFE() macro below.  This is
+// due to a limitation in C++'s template system.  The limitation might
+// eventually be removed, but it hasn't happened yet.

+// ARRAYSIZE_UNSAFE performs essentially the same calculation as arraysize,
+// but can be used on anonymous types or types defined inside
+// functions.  It's less safe than arraysize as it accepts some
+// (although not all) pointers.  Therefore, you should use arraysize
+// whenever possible.
+//
+// The expression ARRAYSIZE_UNSAFE(a) is a compile-time constant of type
+// size_t.
+//
+// ARRAYSIZE_UNSAFE catches a few type errors.  If you see a compiler error
+//
+//   "warning: division by zero in ..."
+//
+// when using ARRAYSIZE_UNSAFE, you are (wrongfully) giving it a pointer.
+// You should only use ARRAYSIZE_UNSAFE on statically allocated arrays.
+//
+// The following comments are on the implementation details, and can
+// be ignored by the users.
+//
+// ARRAYSIZE_UNSAFE(arr) works by inspecting sizeof(arr) (the # of bytes in
+// the array) and sizeof(*(arr)) (the # of bytes in one array
+// element).  If the former is divisible by the latter, perhaps arr is
+// indeed an array, in which case the division result is the # of
+// elements in the array.  Otherwise, arr cannot possibly be an array,
+// and we generate a compiler error to prevent the code from
+// compiling.
+//
+// Since the size of bool is implementation-defined, we need to cast
+// !(sizeof(a) & sizeof(*(a))) to size_t in order to ensure the final
+// result has type size_t.
+//
+// This macro is not perfect as it wrongfully accepts certain
+// pointers, namely where the pointer size is divisible by the pointee
+// size.  Since all our code has to go through a 32-bit compiler,
+// where a pointer is 4 bytes, this means all pointers to a type whose
+// size is 3 or greater than 4 will be (righteously) rejected.

-This version of init contains code to perform "bootcharting", i.e. generating log
-files that can be later processed by the tools provided by www.bootchart.org.
-
-To activate it, you need to define build 'init' with the INIT_BOOTCHART environment
-variable defined to 'true', for example:
-
-    touch system/init/init.c
-    m INIT_BOOTCHART=true
-
-On the emulator, use the new -bootchart <timeout> option to boot with bootcharting
-activated for <timeout> seconds.
-
-Otherwise, flash your device, and start it. Then create a file on the /data partition
-with a command like the following:
-
-  adb shell 'echo $TIMEOUT > /data/bootchart-start'
-
-Where the value of $TIMEOUT corresponds to the wanted bootcharted period in seconds;
-for example, to bootchart for 2 minutes, do:
-
-  adb shell 'echo 120 > /data/bootchart-start'
-
-Reboot your device, bootcharting will begin and stop after the period you gave.
-You can also stop the bootcharting at any moment by doing the following:
-
-  adb shell 'echo 1 > /data/bootchart-stop'
-
-Note that /data/bootchart-stop is deleted automatically by init at the end of the
-bootcharting. This is not the case of /data/bootchart-start, so don't forget to delete it
-when you're done collecting data:
-
-  adb shell rm /data/bootchart-start
-
-The log files are placed in /data/bootchart/. you must run the script tools/grab-bootchart.sh
-which will use ADB to retrieve them and create a bootchart.tgz file that can be used with
-the bootchart parser/renderer, or even uploaded directly to the form located at:
-
-  http://www.bootchart.org/download.html
-
-NOTE: the bootchart.org webform doesn't seem to work at the moment, you can generate an
-      image on your machine by doing the following:
-
-         1/ download the sources from www.bootchart.org
-         2/ unpack them
-         3/ in the source directory, type 'ant' to build the bootchart program
-         4/ type 'java -jar bootchart.jar /path/to/bootchart.tgz
-
-technical note:
-
-this implementation of bootcharting does use the 'bootchartd' script provided by
-www.bootchart.org, but a C re-implementation that is directly compiled into our init
-program.

+On the emulator, use the new -bootchart <timeout> option to boot with
+bootcharting activated for <timeout> seconds.
 
-   mount tmpfs tmpfs /dev
-   mkdir /dev/pts
-   mkdir /dev/socket
-   mount devpts devpts /dev/pts
-   mount proc proc /proc
-   mount sysfs sysfs /sys
+On a device, create /data/bootchart/start with a command like the following:
 
-   write /proc/cpu/alignment 4
+  adb shell 'echo $TIMEOUT > /data/bootchart/start'
 
-   ifup lo
+Where the value of $TIMEOUT corresponds to the desired bootcharted period in
+seconds. Bootcharting will stop after that many seconds have elapsed.
+You can also stop the bootcharting at any moment by doing the following:
 
-   hostname localhost
-   domainname localhost
+  adb shell 'echo 1 > /data/bootchart/stop'
 
-   mount yaffs2 mtd@system /system
-   mount yaffs2 mtd@userdata /data
+Note that /data/bootchart/stop is deleted automatically by init at the end of
+the bootcharting. This is not the case with /data/bootchart/start, so don't
+forget to delete it when you're done collecting data.
 
-   import /system/etc/init.conf
+The log files are written to /data/bootchart/. A script is provided to
+retrieve them and create a bootchart.tgz file that can be used with the
+bootchart command-line utility:
 
-   class_start default
+  sudo apt-get install pybootchartgui
+  ANDROID_SERIAL=<device serial number>
+  $ANDROID_BUILD_TOP/system/core/init/grab-bootchart.sh

-Debugging notes
----------------
+Debugging init
+--------------
 By default, programs executed by init will drop stdout and stderr into
 /dev/null. To help with debugging, you can execute your program via the
-Andoird program logwrapper. This will redirect stdout/stderr into the
+Android program logwrapper. This will redirect stdout/stderr into the
 Android logging system (accessed via logcat).
 
 For example
 service akmd /system/bin/logwrapper /sbin/akmd
+
+For quicker turnaround when working on init itself, use:
+
+  mm -j
+  m ramdisk-nodeps
+  m bootimage-nodeps
+  adb reboot bootloader
+  fastboot boot $ANDROID_PRODUCT_OUT/boot.img
+
+Alternatively, use the emulator:
+
+  emulator -partition-size 1024 -verbose -show-kernel -no-window
+
+You might want to call klog_set_level(6) after the klog_init() call
+so you see the kernel logging in dmesg (or the emulator output).

- * Backtracing functions for ARM.
- *
- * This implementation uses the exception unwinding tables provided by
- * the compiler to unwind call frames.  Refer to the ARM Exception Handling ABI
- * documentation (EHABI) for more details about what's going on here.
- *
- * An ELF binary may contain an EXIDX section that provides an index to
- * the exception handling table of each function, sorted by program
- * counter address.
- *
- * This implementation also supports unwinding other processes via ptrace().
- * In that case, the EXIDX section is found by reading the ELF section table
- * structures using ptrace().
- *
- * Because the tables are used for exception handling, it can happen that
- * a given function will not have an exception handling table.  In particular,
- * exceptions are assumed to only ever be thrown at call sites.  Therefore,
- * by definition leaf functions will not have exception handling tables.
- * This may make unwinding impossible in some cases although we can still get
- * some idea of the call stack by examining the PC and LR registers.
- *
- * As we are only interested in backtrace information, we do not need
- * to perform all of the work of unwinding such as restoring register
- * state and running cleanup functions.  Unwinding is performed virtually on
- * an abstract machine context consisting of just the ARM core registers.
- * Furthermore, we do not run generic "personality functions" because
- * we may not be in a position to execute arbitrary code, especially if
- * we are running in a signal handler or using ptrace()!

-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

+       If messages fail, a negative error code will be returned to the caller.
+
+       The -ENOTCONN return code indicates that the logger daemon is stopped.
+
+       The  -EBADF return code indicates that the log access point can not be
+       opened, or the log buffer id is out of range.
+
+       For the  -EAGAIN  return code,  this means that the logging message was
+       temporarily backed-up either because of Denial Of Service (DOS) logging
+       pressure from some chatty application or service in the Android system,
+       or if too small of a value is set in /proc/sys/net/unix/max_dgram_qlen.
+       To aid in diagnosing the occurence of this,  a binary event from liblog
+       will be sent to the  log  daemon  once a  new  message  can get through
+       indicating how many  messages were  dropped  as a result.   Please take
+       action to resolve the structural problems at the source.
+
+       It is generally not advised for the caller to retry the  -EAGAIN return
+       code as  this  will  only  make the  problem(s)  worse  and  cause your
+       application to temporarily drop to the  logger daemon  priority,  BATCH
+       scheduling policy and background task cgroup. If you require a group of
+       messages to be passed atomically,  merge  them  into  one  message with
+       embedded newlines to the maximum length LOGGER_ENTRY_MAX_PAYLOAD.
+
+       Other return codes  from  writing operation can be returned.  Since the
+       library retries on EINTR, -EINTR should never be returned.

+I learn in this letter that Don Peter of Arragon\n\
+comes this night to Messina\n\
+MESSENGER\n\
+He is very near by this: he was not three leagues off\n\
+when I left him\n\
+LEONATO\n\
+How many gentlemen have you lost in this action?\n\
+MESSENGER\n\
+But few of any sort, and none of name\n\
+LEONATO\n\
+A victory is twice itself when the achiever brings\n\
+home full numbers. I find here that Don Peter hath\n\
+bestowed much honour on a young Florentine called Claudio\n\
+MESSENGER\n\
+Much deserved on his part and equally remembered by\n\
+Don Pedro: he hath borne himself beyond the\n\
+promise of his age, doing, in the figure of a lamb,\n\
+the feats of a lion: he hath indeed better\n\
+bettered expectation than you must expect of me to\n\
+tell you how\n\
+LEONATO\n\
+He hath an uncle here in Messina will be very much\n\
+glad of it.\n\
+MESSENGER\n\
+I have already delivered him letters, and there\n\
+appears much joy in him; even so much that joy could\n\
+not show itself modest enough without a badge of\n\
+bitterness.\n\
+LEONATO\n\
+Did he break out into tears?\n\
+MESSENGER\n\
+In great measure.\n\
+LEONATO\n\
+A kind overflow of kindness: there are no faces\n\
+truer than those that are so washed. How much\n\
+better is it to weep at joy than to joy at weeping!\n\
+BEATRICE\n\
+I pray you, is Signior Mountanto returned from the\n\
+wars or no?\n\
+MESSENGER\n\
+I know none of that name, lady: there was none such\n\
+in the army of any sort.\n\
+LEONATO\n\
+What is he that you ask for, niece?\n\
+HERO\n\
+My cousin means Signior Benedick of Padua.\n\
+MESSENGER\n\
+O, he's returned; and as pleasant as ever he was.\n\
+BEATRICE\n\
+He set up his bills here in Messina and challenged\n\
+Cupid at the flight; and my uncle's fool, reading\n\
+the challenge, subscribed for Cupid, and challenged\n\
+him at the bird-bolt. I pray you, how many hath he\n\
+killed and eaten in these wars? But how many hath\n\
+he killed? for indeed I promised to eat all of his killing.\n\
+LEONATO\n\
+Faith, niece, you tax Signior Benedick too much;\n\
+but he'll be meet with you, I doubt it not.\n\
+MESSENGER\n\
+He hath done good service, lady, in these wars.\n\
+BEATRICE\n\
+You had musty victual, and he hath holp to eat it:\n\
+he is a very valiant trencherman; he hath an\n\
+excellent stomach.\n\
+MESSENGER\n\
+And a good soldier too, lady.\n\
+BEATRICE\n\
+And a good soldier to a lady: but what is he to a lord?\n\
+MESSENGER\n\
+A lord to a lord, a man to a man; stuffed with all\n\
+honourable virtues.\n\
+BEATRICE\n\
+It is so, indeed; he is no less than a stuffed man:\n\
+but for the stuffing,--well, we are all mortal.\n\
+LEONATO\n\
+You must not, sir, mistake my niece. There is a\n\
+kind of merry war betwixt Signior Benedick and her:\n\
+they never meet but there's a skirmish of wit\n\
+between them.\n\
+BEATRICE\n\
+Alas! he gets nothing by that. In our last\n\
+conflict four of his five wits went halting off, and\n\
+now is the whole man governed with one: so that if\n\
+he have wit enough to keep himself warm, let him\n\
+bear it for a difference between himself and his\n\
+horse; for it is all the wealth that he hath left,\n\
+to be known a reasonable creature. Who is his\n\
+companion now? He hath every month a new sworn brother.\n\
+MESSENGER\n\
+Is't possible?\n\
+BEATRICE\n\
+Very easily possible: he wears his faith but as\n\
+the fashion of his hat; it ever changes with the\n\
+next block.\n\
+MESSENGER\n\
+I see, lady, the gentleman is not in your books.\n\
+BEATRICE\n\
+No; an he were, I would burn my study. But, I pray\n\
+you, who is his companion? Is there no young\n\
+squarer now that will make a voyage with him to the devil?\n\
+MESSENGER\n\
+He is most in the company of the right noble Claudio.\n\
+BEATRICE\n\
+O Lord, he will hang upon him like a disease: he\n\
+is sooner caught than the pestilence, and the taker\n\
+runs presently mad. God help the noble Claudio! if\n\
+he have caught the Benedick, it will cost him a\n\
+thousand pound ere a' be cured.\n\
+MESSENGER\n\
+I will hold friends with you, lady.\n\
+BEATRICE\n\
+Do, good friend.\n\
+LEONATO\n\
+You will never run mad, niece.\n\
+BEATRICE\n\
+No, not till a hot January.\n\
+MESSENGER\n\
+Don Pedro is approached.\n\
+Enter DON PEDRO, DON JOHN, CLAUDIO, BENEDICK, and BALTHASAR\n\
+\n\
+DON PEDRO\n\
+Good Signior Leonato, you are come to meet your\n\

+cost, and you encounter it\n\

-NETLINK OVERVIEW
-
-* Each netlink message consists of a bitstream with a netlink header.
-* After this header a second header *can* be used specific to the netlink
-  family in use. This library was tested using the generic netlink
-  protocol defined by struct genlmsghdr to support nl80211.
-* After the header(s) netlink attributes can be appended to the message
-  which hold can hold basic types such as unsigned integers and strings.
-* Attributes can also be nested. This is accomplished by calling "nla_nest_start"
-  which creates an empty attribute with nest attributes as its payload. Then to
-  close the nest, "nla_nest_end" is called.
-* All data structures in this implementation are byte-aligned (Currently 4 bytes).
-* Acknowledgements (ACKs) are sent as NLMSG_ERROR netlink message types (0x2) and
-  have an error value of 0.
-
-KNOWN ISSUES
-
-  GENERAL
-  * Not tested for thread safety
-
-  Android.mk
-  * No dynamic library because of netlink cache not implemented and
-    not tested for thread safety
-
-  attr.c
-  * nla_parse - does not use nla_policy argument
-
-  cache.c
-  * netlink cache not implemented and only supports one netlink family id
-    which is stored in the nl_cache pointer instead of an actual cache
-
-  netlink.c
-  * nl_recvmsgs - does not support nl_cb_overwrite_recv()
-  * nl_recv - sets/unsets asynchronous socket flag
-

+Auditd Daemon
+
+The audit daemon is a simplified version of its desktop
+counterpart designed to gather the audit logs from the
+audit kernel subsystem. The audit subsystem of the kernel
+includes Linux Security Modules (LSM) messages as well.
+
+To enable the audit subsystem, you must add this to your
+kernel config:
+CONFIG_AUDIT=y
+
+To enable a LSM, you must consult that LSM's documentation, the
+example below is for SELinux:
+CONFIG_SECURITY_SELINUX=y
+
+This does not include possible dependencies that may need to be
+satisfied for that particular LSM.
