     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
+
+reverse:<forward-command>
+    This implements the 'adb reverse' feature, i.e. the ability to reverse
+    socket connections from a device to the host. <forward-command> is one
+    of the forwarding commands that are described above, as in:
+
+      list-forward
+      forward:<local>;<remote>
+      forward:norebind:<local>;<remote>
+      killforward-all
+      killforward:<local>
+
+    Note that in this case, <local> corresponds to the socket on the device
+    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.

-      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.

- * 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()!

-   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
-
-   1. Definitions.
-
-      "License" shall mean the terms and conditions for use, reproduction,
-      and distribution as defined by Sections 1 through 9 of this document.
-
-      "Licensor" shall mean the copyright owner or entity authorized by
-      the copyright owner that is granting the License.
-
-      "Legal Entity" shall mean the union of the acting entity and all
-      other entities that control, are controlled by, or are under common
-      control with that entity. For the purposes of this definition,
-      "control" means (i) the power, direct or indirect, to cause the
-      direction or management of such entity, whether by contract or
-      otherwise, or (ii) ownership of fifty percent (50%) or more of the

-
-      "You" (or "Your") shall mean an individual or Legal Entity
-      exercising permissions granted by this License.
-
-      "Source" form shall mean the preferred form for making modifications,
-      including but not limited to software source code, documentation
-      source, and configuration files.
-
-      "Object" form shall mean any form resulting from mechanical
-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain
-      separable from, or merely link (or bind by name) to the interfaces of,
-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of
-      the copyright owner. For the purposes of this definition, "submitted"
-      means any form of electronic, verbal, or written communication sent
-      to the Licensor or its representatives, including but not limited to
-      communication on electronic mailing lists, source code control systems,
-      and issue tracking systems that are managed by, or on behalf of, the
-      Licensor for the purpose of discussing and improving the Work, but
-      excluding communication that is conspicuously marked or otherwise
-      designated in writing by the copyright owner as "Not a Contribution."
-
-      "Contributor" shall mean Licensor and any individual or Legal Entity
-      on behalf of whom a Contribution has been received by Licensor and
-      subsequently incorporated within the Work.
-
-   2. Grant of Copyright 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
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   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.
-
-   END OF TERMS AND CONDITIONS

+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\
+trouble: the fashion of the world is to avoid\n\
+cost, and you encounter it\n\
+LEONATO\n\
+Never came trouble to my house in the likeness";

-Netlink Protocol Library
-
-This library is a clean room re-implementation of libnl 2.0 and
-re-licensed under Apache 2.0. It was developed primarily to support
-wpa_supplicant. However, with additional development can be extended
-to support other netlink applications.

-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
-

+//   knee in the average time between log messages at this point,
+//   so we do not necessarily have to compare the rate against the
+//   measured performance (BM_log_maximum_retry) of the logger.
+//
+//   for example (reformatted):
+//
+//       Minimum time between log events per dgram_qlen:
+//       1   2   3   5   10  20  30  50  100  200 300 400 500 600

+//
+//   demonstrates a clear knee rising at 100, so this means that for this
+//   case max_dgram_qlen = 100 would be more than sufficient to handle the
+//   worst that the system could stuff into the logger. The
+//   BM_log_maximum_retry performance (derated by the log collection) on the
+//   same system was 33.2us so we would almost be fine with max_dgram_qlen = 50.
+//   BM_log_maxumum_retry with statistics off is roughly 20us, so

+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.

+ * This is an expensive way to keep people from recovering files from your
+ * non-snapshotted FFS filesystems using fsdb(8).  Really.  No more.  Only
+ * regular files are deleted, directories (and therefore names) will remain.
+ * Also, this assumes a fixed-block file system (like FFS, or a V7 or a
+ * System V file system).  In a logging file system, you'll have to have
+ * kernel support.
+ *
+ * A note on standards:  U.S. DoD 5220.22-M "National Industrial Security
+ * Program Operating Manual" ("NISPOM") is often cited as a reference
+ * for clearing and sanitizing magnetic media.  In fact, a matrix of
+ * "clearing" and "sanitization" methods for various media was given in
+ * Chapter 8 of the original 1995 version of NISPOM.  However, that
+ * matrix was *removed from the document* when Chapter 8 was rewritten
+ * in Change 2 to the document in 2001.  Recently, the Defense Security
+ * Service has made a revised clearing and sanitization matrix available
+ * in Microsoft Word format on the DSS web site.  The standardization
+ * status of this matrix is unclear.  Furthermore, one must be very
+ * careful when referring to this matrix: it is intended for the "clearing"
+ * prior to reuse or "sanitization" prior to disposal of *entire media*,
+ * not individual files and the only non-physically-destructive method of
+ * "sanitization" that is permitted for magnetic disks of any kind is
+ * specifically noted to be prohibited for media that have contained
+ * Top Secret data.
+ *
+ * It is impossible to actually conform to the exact procedure given in
+ * the matrix if one is overwriting a file, not an entire disk, because
+ * the procedure requires examination and comparison of the disk's defect
+ * lists.  Any program that claims to securely erase *files* while 
+ * conforming to the standard, then, is not correct.  We do as much of
+ * what the standard requires as can actually be done when erasing a
+ * file, rather than an entire disk; but that does not make us conformant.
+ *
+ * Furthermore, the presence of track caches, disk and controller write
+ * caches, and so forth make it extremely difficult to ensure that data
+ * have actually been written to the disk, particularly when one tries
+ * to repeatedly overwrite the same sectors in quick succession.  We call
+ * fsync(), but controllers with nonvolatile cache, as well as IDE disks
+ * that just plain lie about the stable storage of data, will defeat this.
+ *
+ * Finally, widely respected research suggests that the given procedure
+ * is nowhere near sufficient to prevent the recovery of data using special
+ * forensic equipment and techniques that are well-known.  This is 
+ * presumably one reason that the matrix requires physical media destruction,
+ * rather than any technique of the sort attempted here, for secret data.
+ *
+ * Caveat Emptor.
+ *
+ * rm_overwrite will return 0 on success.
