* vold: Honor mount options for ext4/f2fs partitionsTom Marshall2020-04-111-1/+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 Marshall2020-04-111-6/+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.

| | | | | | | | | | | | | | | | | | | | | | When running a live GSI, userdata is a logical partition. If we don't fix up the fstab we'll derive the underlying block device instead of the device-mapper node for userdat_gsi, resulting in a corrupt data partition for both images.

* | Bind mount pkg specific dirs in the zygote child namespaces.Sudheer Shanka2018-09-271-1/+1
|/ | | | | | | | | | | | | | | - Also update vold to create sandboxes for secondary storage devices. - Since bind mounts are created in the process specific namespaces, we don't need /mnt/storage anymore which we were using it to prevent some bind mounts from propagating onto /mnt/runtime/write. - Create bind mounts for {media,obb} dirs similar to data dir in per process namespace. - Also fix a bug where we are not passing correct packages to vold when a new user starts.

| | | | | | | | | | | | | | | | | | Moves away from crufty char* operations to std::string utility methods, including android::base methods for splitting/parsing. Rewrite of how Process handles scanning procfs for filesystem references; now uses fts(3) for more sane traversal. Replace sscanf() with new FindValue() method, also has unit tests. Remove some unused methods. Switch almost everyone over to using modern logging library.

* Move even more vold commands over to Binder.Jeff Sharkey2017-09-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | This moves fstrim, obb and appfuse commands over to the new Binder interface. 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.

* Fix deadlock between vold and initDimitry Ivanov2017-01-191-6/+11
| | | | | | | | | | | | | | | | By setting property after listeners are initialized we avoid deadlock between vold and init where vold is waiting on property_service while init is blocked (and therefore is not able to accept connections) on vdc which is attempting to communicate with vold.

* Trim both internal and adopted private storage.Jeff Sharkey2015-07-011-14/+4
| | | | | | | | | | | | | Refactor fstrim code to be encapsulated in unique task object, and give it option of benchmarking when finished. Trimming now includes both storage from fstab and adopted private volumes. Cleaner timing stats are logged for each unique volume. Add wakelock during ongoing async move tasks. Push disk sysfs path to framework so it can parse any SD card registers as desired. Bug: 21831325 Change-Id: I76577685f5cae4929c251ad314ffdaeb5eb1c8bf
* Add f2fs support for private volumes.Jeff Sharkey2015-06-081-0/+5
| | | | | | | | | | | | | | When formatting volumes, pass along fsType string which can be "auto" to let the volume select the best choice. For now, private volumes assume that MMC devices (like SD cards) are best off using f2fs when both kernel support and tools are present, otherwise fall back to ext4. Use blkid when mounting to pick the right set of tools. Move filesystem utility methods into namespaces and place in separate directory to be more organized.

* Move crypt commands to a different listener in voldPaul Lawrence2015-06-041-0/+9
| | | | | | | | | | | In order to prevent this bug from happening, we must allow vold cryptfs commands to complete while a long running mount is underway. While waiting for vold to be changed to a binder interface, we will simply create two listeners, one for cryptfs and one for everything else.

* Different blkid and fsck execution domains.Jeff Sharkey2015-04-011-12/+37
| | | | | | | | | | | | vold works with two broad classes of block devices: untrusted devices that come in from the wild, and trusted devices like PrivateVolume which are encrypted. When running blkid and fsck, we pick which SELinux execution domain to use based on which class the device belongs to. Bug: 19993667 Change-Id: I2695f028710a4863f0c3b2ed6da437f466401272
* Progress towards dynamic storage support.Jeff Sharkey2015-03-301-36/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wire up new Disk and VolumeBase objects and events to start replacing older DirectVolume code. Use filesystem UUID as visible PublicVolume name to be more deterministic. When starting, create DiskSource instances based on fstab, and watch for kernel devices to appear. Turn matching devices into Disk objects, scan for partitions, and create any relevant VolumeBase objects. Broadcast all of these events towards userspace so the framework can decide what to mount. Keep track of the primary VolumeBase, and update the new per-user /storage/self/primary symlink for all started users. Provide a reset command that framework uses to start from a known state when runtime is restarted. When vold is unexpectedly killed, try recovering by unmounting everything under /mnt and /storage before moving forward. Remove UMS sharing support for now, since no current devices support it; MTP is the recommended solution going forward because it offers better multi-user support. Switch killProcessesWithOpenFiles() to directly take signal. Fix one SOCK_CLOEXEC bug, but SELinux says there are more lurking. Bug: 19993667 Change-Id: I2dad1303aa4667ec14c52f774e2a28b3c1c1ff6d
* Set SELinux contexts on device nodes created by vold.Stephen Smalley2014-09-301-0/+7
| | | | | | | | | | | | | | | | Extend vold to look up and set SELinux contexts on the device nodes it creates for extra loop devices and for volumes. Prior to this change, these device nodes simply inherited the type of their parent directory /dev/block, i.e. block_device, and vold therefore required create_file perms to block_device:blk_file. With this change we can scope vold down to accessing specific block device types. This depends on change Id3bea28f5958086716cd3db055bea309b3b5fa5a to allow vold to use setfscreatecon().

* vold: set klog level so e2fsck output is loggedKen Sumrall2013-04-101-0/+4
| | | | | | | | | When mounting an encrypted filesystem vold calls fs_mgr, which will call e2fsck on the fielsystem if it's configured to, and fs_mgr will attempt to log the output the kernel log. However, if won't log anything unless the klog level is set to 6, aka INFO. Change-Id: I8ac34941330262ea3414681b872fbbeb75391461
