* am f37bfb32: am 23aeeff5: Merge "Use the correct fuse_init_out structure size."Christopher Ferris2014-09-161-2/+28
|\ | | | | | | | | * commit 'f37bfb32eb82393d14e339684c9f508cea3b0ab4': Use the correct fuse_init_out structure size.
| * Use the correct fuse_init_out structure size.Christopher Ferris2014-09-151-2/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | Kernel 2.6.16 is the first stable kernel with struct fuse_init_out defined (fuse version 7.6). The structure is the same from 7.6 through 7.22. Beginning with 7.23, the structure increased in size and added new parameters. If the kernel only works on minor revs older than or equal to 22, then use the older structure size since this code only uses the 7.22 version of the structure.

| | | | | | | | | | | | | | | | | Before this change, FUSE lookup() would have the side effect of creating the directory on behalf of apps. This resulted in most directories being created just by Settings trying to measure disk space. Instead, we're switching to have vold do directory creation when an app doesn't have enough permissions. Create fs_mkdirs() utility to create all parent directories in a path as needed. Allow traversal (+x) into /storage directories. Fix FUSE derived permissions to be case insensitive. Mark well-known directories as .nomedia when created. Bug: 10577808, 10330221 Change-Id: I53114f2e63ffbe6de4ba6a72d94a232523231cad

| | | | | | | | | | | | | | | | | | | | The fuse_open_out structure returned to the kernel by handle_opendir() was not properly initializing all the fields.

Mirror single OBB directory between all users without requiring fancy bind mounts by letting a nodes graft in another part of the underlying tree. Move to everything having "sdcard_r" GID by default, and verify that calling apps hold "sdcard_rw" when performing mutations. Determines app group membership from new packages.list column. Flag to optionally enable sdcard_pics/sdcard_av permissions splitting. Flag to supply a default GID for all files. Ignore attempts to access security sensitive files. Fix run-as to check for new "package_info" GID. Change-Id: Id5f3680779109141c65fb8fa1daf56597f49ea0d
* | Richer SD card permissions through FUSE.Jeff Sharkey2013-08-082-57/+371
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes the FUSE daemon to synthesize an Android-specific set of filesystem permissions, even when the underlying media storage is permissionless. This is designed to support several features: First, apps can access their own files in /Android/data/com.example/ without requiring any external storage permissions. This is enabled by allowing o+x on parent directories, and assigning the UID owner based on the directory name (package name). The mapping from package to appId is parsed from packages.list, which is updated when apps are added/removed. Changes are observed through inotify. It creates missing package name directories when requested and valid. Second, support for separate permissions for photos and audio/video content on the device through new GIDs which are assigned based on top-level directory names. Finally, support for multi-user separation on the same physical media through new /Android/user/ directory, which will be bind-mounted into place. It recursively applies the above rules to each secondary user. rwxrwx--x root:sdcard_rw / rwxrwx--- root:sdcard_pics /Pictures rwxrwx--- root:sdcard_av /Music rwxrwx--x root:sdcard_rw /Android rwxrwx--x root:sdcard_rw /Android/data rwxrwx--- u0_a12:sdcard_rw /Android/data/com.example rwxrwx--x root:sdcard_rw /Android/obb/ rwxrwx--- u0_a12:sdcard_rw /Android/obb/com.example rwxrwx--- root:sdcard_all /Android/user rwxrwx--x root:sdcard_rw /Android/user/10 rwxrwx--- u10_a12:sdcard_rw /Android/user/10/Android/data/com.example These derived permissions are disabled by default. Switched option parsing to getopt(). Change-Id: I21bf5d79d13f0f07a6a116122b16395f4f97505b
* Raise the max file open limit in sdcardKen Sumrall2013-02-111-0/+9
| | | | | | | | | | | | The default is 1024 files, and in some testing, the limit has been hit. This raises the limit to 8192. Going higher starts to cause performance issues (I started to notice that around 16K open files in my testing) as sdcard does linear searches. If a higher max is needed, then the sdcard daemon will need some optimizations. Bug: 7442187 Change-Id: I7aba7f4556ed70651f36244294a6756f3d6b8963

| | | | | | | | | | | | | | | | | | | | | | | | | | Clang turned up some signed/unsigned comparison warnings. These warnings have been fixed by cleaning up sdcard slightly: - Don't use negative numbers for invalid gid/uid. - sdcard takes a fixed number of arguments now so assert on that instead of using a for loop. - Also fixed usage string to reflect this fact.

* | Make sdcard daemon multi-threaded.Jeff Brown2012-06-042-595/+638
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The essential idea here is that a handler thread only needs to hold a lock on the global node table while it is manipulating nodes. The actual I/O operation is then performed without holding any locks. By default, we use 2 threads but this can be configured on the command-line. Work is sheduled somewhat arbitrarily by the handler threads. Whichever thread happens to read() the next request first wins the right process it. This policy is very simple but potentially wastes threads when there isn't much work to be done. We can always improve this later if needed. Change-Id: Id27a27c2c9b40d4f8e35a6bef9dd84f0dfacf337

Be more careful about how the request header and data payload are extracted. For example, the old code did len -= hdr->len, but since len == hdr->len, this value was always 0. It turns out we didn't use len thereafter, but we might want to for sanity checking incoming requests. Use const to make it clearer what data is coming out of the request. Removed spurious error reply from FUSE_WRITE. It serves no purpose and is ignored by the kernel. Bug: 6488845 Change-Id: Ia328532979868f0aaea43744a49662f2f4511bfe

* sdcard: Fix lower case squashing for case insensitivity support.Mike Lockwood2011-01-171-21/+10
| | | | | | | | | | | | | | | | | | | | | | The fuse layer in the kernel does not support case insensitive file systems. But the sdcard daemon's fuse_lookup was returning the same file object for different file names, which caused problems in the kernel fuse layer's dcache, resulting in EBUSY errors if the same directory was opened twice under different names differing only by case. To fix this, the sdcard daemon will return different file objects for files or directories that differ only by case. Now the squashing occurs only in the interaction between the sdcard daemon and the underlying file system in /data/media, and sdcard maintains the illusion for the kernel fuse layer that there are two separate files. Example: Suppose both /mnt/sdcard/foo.txt and /mnt/sdcard/FOO.TXT are opened. Previously, the sdcard would squash this to a single node, and return the same node to the kernel fuse implementation twice, and would open the underlying file /data/media/foo.txt only once. Now sdcard will create two separate nodes will open /data/media/foo.txt twice, once for mnt/sdcard/foo.txt and again for /mnt/sdcard/FOO.TXT.
