+
+/*
+ * Implementation of the POSIX open_memstream() function, which Linux has
+ * but BSD lacks.
+ *
+ * Summary:
+ * - Works like a file-backed FILE* opened with fopen(name, "w"), but the
+ *   backing is a chunk of memory rather than a file.
+ * - The buffer expands as you write more data.  Seeking past the end
+ *   of the file and then writing to it zero-fills the gap.
+ * - The values at "*bufp" and "*sizep" should be considered read-only,
+ *   and are only valid immediately after an fflush() or fclose().
+ * - A '\0' is maintained just past the end of the file. This is not included
+ *   in "*sizep".  (The behavior w.r.t. fseek() is not clearly defined.
+ *   The spec says the null byte is written when a write() advances EOF,
+ *   but it looks like glibc ensures the null byte is always found at EOF,
+ *   even if you just seeked backwards.  The example on the opengroup.org
+ *   page suggests that this is the expected behavior.  The null must be
+ *   present after a no-op fflush(), which we can't see, so we have to save
+ *   and restore it.  Annoying, but allows file truncation.)
+ * - After fclose(), the caller must eventually free(*bufp).
+ *
+ * This is built out of funopen(), which BSD has but Linux lacks.  There is
+ * no flush() operator, so we need to keep the user pointers up to date
+ * after each operation.
+ *
+ * I don't think Windows has any of the above, but we don't need to use
+ * them there, so we just supply a stub.

+ * CHA (Cursor Horizontal Absolute)
+ *    Sequence: ESC [ n G
+ *    Effect: moves cursor to column n
+ *
+ * EL (Erase Line)
+ *    Sequence: ESC [ n K
+ *    Effect: if n is 0 or missing, clear from cursor to end of line
+ *    Effect: if n is 1, clear from beginning of line to cursor
+ *    Effect: if n is 2, clear entire line
+ *
+ * CUF (CUrsor Forward)
+ *    Sequence: ESC [ n C
+ *    Effect: moves cursor forward of n chars

-#
-# Tag names are one or more ASCII letters and numbers or underscores, i.e.

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+
+   2. Grant of Copyright License. Subject to the terms and conditions of

+      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

+      modifications, and in Source or Object form, provided that You

+
+      (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,

+      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

+      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

+      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.

+ *  WARNING WARNING WARNING WARNING
+ *
+ *  This program runs as set-uid root on Android production devices.
+ *  Be very conservative when modifying it to avoid any serious
+ *  security issue. Keep in mind the following:
+ *
+ *  - This program should only run for the 'root' or 'shell' users
+ *
+ *  - Statically link against the C library, and avoid anything that
+ *    is more complex than simple system calls until the uid/gid has
+ *    been dropped to that of a normal user or you are sure to exit.
+ *
+ *    This avoids depending on environment variables, system properties
+ *    and other external factors that may affect the C library in
+ *    unpredictable ways.
+ *
+ *  - Do not trust user input and/or the filesystem whenever possible.
+ *
+ *  Read README.TXT for more details.
+ *
+ *
+ *
+ * The purpose of this program is to run a command as a specific
+ * application user-id. Typical usage is:
+ *
+ *   run-as <package-name> <command> <args>
+ *
+ *  The 'run-as' binary is setuid, but will check the following:
+ *
+ *  - that it is invoked from the 'shell' or 'root' user (abort otherwise)
+ *  - that '<package-name>' is the name of an installed and debuggable package
+ *  - that the package's data directory is well-formed (see package.c)
+ *
+ *  If so, it will cd to the package's data directory, drop to the application's
+ *  user id / group id then run the command there.
+ *
+ *  This can be useful for a number of different things on production devices:
+ *
+ *  - Allow application developers to look at their own applicative data
+ *    during development.
+ *
+ *  - Run the 'gdbserver' binary executable to allow native debugging
