- * WARNING WARNING WARNING WARNING
- *
- * This program runs with CAP_SETUID and CAP_SETGID capabilities 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
- *
- * - 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 installed with CAP_SETUID and CAP_SETGID file
- * capabilities, 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 drop to the application's user id / group id, cd to the
- * package's data directory, then run the command there.
- *
- * NOTE: In the future it might not be possible to cd to the package's data
- * directory under that package's user id / group id, in which case this
- * utility will need to be changed accordingly.
- *
- * 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

-/* README
- *
- * What is this?
- *
- * sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
- * directory permissions (all files are given fixed owner, group, and
- * permissions at creation, owner, group, and permissions are not
- * changeable, symlinks and hardlinks are not createable, etc.
- *
- * See usage() for command line options.
- *
- * It must be run as root, but will drop to requested UID/GID as soon as it
- * mounts a filesystem. It will refuse to run if requested UID/GID are zero.
- *
- * Things I believe to be true:
- *
- * - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
- * CREAT) must bump that node's refcount
- * - don't forget that FORGET can forget multiple references (req->nlookup)
- * - if an op that returns a fuse_entry fails writing the reply to the
- * kernel, you must rollback the refcount to reflect the reference the
- * kernel did not actually acquire
- *
- * This daemon can also derive custom filesystem permissions based on directory
- * structure when requested. These custom permissions support several features:
- *
- * - Apps can access their own files in /Android/data/com.example/ without
- * requiring any additional GIDs.
- * - Separate permissions for protecting directories like Pictures and Music.
- * - Multi-user separation on the same physical device.

+// What is this?
+//
+// sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
+// directory permissions (all files are given fixed owner, group, and
+// permissions at creation, owner, group, and permissions are not
+// changeable, symlinks and hardlinks are not createable, etc.
+//
+// See usage() for command line options.
+//
+// It must be run as root, but will drop to requested UID/GID as soon as it
+// mounts a filesystem. It will refuse to run if requested UID/GID are zero.
+//
+// Things I believe to be true:
+//
+// - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
+// CREAT) must bump that node's refcount
+// - don't forget that FORGET can forget multiple references (req->nlookup)
+// - if an op that returns a fuse_entry fails writing the reply to the
+// kernel, you must rollback the refcount to reflect the reference the
+// kernel did not actually acquire
+//
+// This daemon can also derive custom filesystem permissions based on directory
+// structure when requested. These custom permissions support several features:
+//
+// - Apps can access their own files in /Android/data/com.example/ without
+// requiring any additional GIDs.
+// - Separate permissions for protecting directories like Pictures and Music.
+// - Multi-user separation on the same physical device.
