faa0935ffb772759f795d6b29c6db6f83e8531c4 13-Jan-2015 Narayan Kamath <narayan@google.com> sdcard : inode numbers must be fully representable as uint32_t.

This works around a bug on on 64 bit kernels + sdcard daemons
where we were using memory addresses as inode numbers.

Vold mounts the sdcard with noexec, but the fuse deamon
mounts with exec, so it is still possible to execute
binaries:

/dev/fuse /storage/sdcard1 fuse rw,nosuid,nodev,relatime,
user_id=1023,group_id=1023,default_permissions,allow_other 0 0

/dev/block/vold/179:65 /mnt/media_rw/sdcard1 vfat rw,dirsync,
nosuid,nodev,noexec,relatime,uid=1023,gid=1023,fmask=0007,
dmask=0007,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,
shortname=mixed,utf8,errors=remount-ro 0 0

With this change both vold and fuse mounts with noexec.

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.

dfe0cbab3f9039f34af1dc9e31faf8155737ec2d 04-Jul-2013 Jeff Sharkey <jsharkey@android.com> Richer SD card permissions through FUSE.

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().

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.

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.

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.

Use constants to specify MAX_READ and MAX_WRITE buffer sizes and
use that to determine the size of the buffers that we need.

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.

For existing files, sdcard will do case insensitive matching
when case sensitive lookup fails.

b94d320b1e7e2a3493147f6763cd2825b111a4d8 18-Jan-2011 Mike Lockwood <lockwood@android.com> sdcard: Fix lower case squashing for case insensitivity support.

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.

>2GB files were failing strangely when pread was used instead of
pread64. Also writing to files should use pwrite64 in case they grow
over 2GB.

In response to a RENAME, we actually need to rename and move the virtual
node. To support this, filenames are now allocated separately, as reallocing
the whole node to accommodate a longer filename would break the direct
mapping of fhs and inodes to fuse pointers.

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.

usage: sdcard <path> <uid> <gid>

It must be run as root, but will change to uid/gid as soon as it
mounts a filesystem on /sdcard. It will refuse to run if uid or
gid are zero.
