* vold: Honor mount options for ext4/f2fs partitionsTom Marshall2020-04-111-2/+10
| | | | | | | | | | | | | * Save mount options and fstype for DiskPartition objects * Pass mount options and fstype to PublicVolume ctor * Pass mount options to ext4::Mount/f2fs:Mount * Use specified/default fstype if blkid fails This is trivially extensible for other fs types.

* vold: Support internal storage partitionsTom Marshall2020-04-111-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | * Support nonremovable disks and expose a nonremovable flag in the DiskCreated message. * New DiskPartition class to hold single partitions. DiskPartition is used when the fs_mgr entry has a partnum (eg. when fs_mgr_flags contains voldmanaged=label:#). Override disk partitioning methods to prevent destroying the emmc.

* Create a new MOUNT_EXTERNAL_LEGACY storage mode.Sudheer Shanka2019-01-181-1/+1
| | | | | | | | | | | | | | | | | | Apps that are already installed on the device before isolated_storage feature is enabled will be granted MOUNT_EXTERNAL_LEGACY mode. In this mode, /mnt/runtime/write will be mounted at /storage giving them same level of access as in P. A new mount directory /mnt/runtime/full is also created which will be used for mounting at /storage for apps started with MOUNT_EXTERNAL_FULL mode. This will allow apps with WRITE_MEDIA_STORAGE permission to read/write anywhere on the secondary devices without needing to bypass sdcardfs.

This change also separates creating/destroying and mounting/unmounting of OBB volumes, which means they finally flow nicely into the modern VolumeInfo/VolumeBase design. We now generate unique identifiers for all OBB volumes, instead of using a shady MD5 hash. Change all "loop" and "dm" devices to tag the kernel resources with a vold-specific prefix so that we can clean them up if vold crashes; there are new destroyAll() methods that handle this cleanup. Move appfuse mounting/unmounting into VolumeManager so it can be shared. Move various model objects into a separate directory to tidy things up.

* Add a new "virtual disk" feature.Jeff Sharkey2017-03-251-0/+3
| | | | | | | | | | | | | | | It's extremely difficult to test storage related logic on devices that don't have physical SD card slots. So to support better debugging and testing, add a new "virtual disk" feature which mounts a 512MB file through loop device. It relies on the kernel having the "loop.max_part" value set to something other than 0 via the boot command line, since that allows all the existing partition logic to fall into place.

* Let's reinvent storage, yet again!Jeff Sharkey2015-06-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we're treating storage as a runtime permission, we need to grant read/write access without killing the app. This is really tricky, since we had been using GIDs for access control, and they're set in stone once Zygote drops privileges. The only thing left that can change dynamically is the filesystem itself, so let's do that. This means changing the FUSE daemon to present itself as three different views: /mnt/runtime_default/foo - view for apps with no access /mnt/runtime_read/foo - view for apps with read access /mnt/runtime_write/foo - view for apps with write access There is still a single location for all the backing files, and filesystem permissions are derived the same way for each view, but the file modes are masked off differently for each mountpoint. During Zygote fork, it wires up the appropriate storage access into an isolated mount namespace based on the current app permissions. When the app is granted permissions dynamically at runtime, the system asks vold to jump into the existing mount namespace and bind mount the newly granted access model into place.

* Initial pass at storage benchmarks.Jeff Sharkey2015-05-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | Now that we're offering to store private app data on adopted storage devices, the performance of those devices is much more important to overall user experience. To help set user expectations, this change offers to execute a real-world benchmark on a storage device, returning a metric that can be used to compare internal and external storage. The benchmark is generated from the strace-instrumented storage access patterns of typical apps. A typical device completes the benchmark in under two seconds on internal storage, a UHS-3 SD card is even faster (!), but a very slow Class 4 SD card takes about 30 seconds to complete, giving us a clear signal. The measured benchmark numbers are logged along with information about the storage device, such as manufacturer, model, etc. Card serial numbers are scrubbed from output.

* Wider volume mutation lock, move force adoptable.Jeff Sharkey2015-04-211-1/+7
| | | | | | | | | | We eventually should move back to per-disk locks, but use a giant lock to keep development rolling forward. Also move force adoptable flag to framework since, since encrypted devices don't have persisted properties loaded early during boot. Bug: 19993667 Change-Id: Ifa3016ef41b038f8f71fc30bc81596cfd21dcd2a
