* clang-format many files.Paul Crowley2018-09-181-7/+8
| | | | | Test: Format-only changes; treehugger suffices. Change-Id: I23cde3f0bbcac13bef555d13514e922c79d5ad48
* Move to modern utility methods from android::base.Jeff Sharkey2017-10-171-2/+0
| | | | | | | | | | | | | | | | | | 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.

* Destroy vold socket interface completely.Jeff Sharkey2017-09-181-5/+0
| | | | | | | | Long live Binder. Test: yes Bug: 13758960 Change-Id: If6be379b5a873f1b0c66dd1522b87413ad10fc46
* 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.

* Add a new "virtual disk" feature.Jeff Sharkey2017-03-251-0/+2
| | | | | | | | | | | | | | | 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. Bug: 34903607 Test: builds, boots, virtual disk works Change-Id: I04c5b33e37319d867542985a56b7999a9b7cf35d
* vold: fix 64 bit ioctl errorMateusz Nowak2015-10-211-2/+2
| | | | | | | | | | | Changing the num_sectors used in ioctl with BLKGETSIZE because the kernel expects an unsigned long type and then changes 64 bits with a 64 bits userspace. This overwrites what's located close to the parameter location if any.

* Fixed type mismatch for ioctl(BLKGETSIZE)Hiroaki Miyazawa2015-03-301-1/+1
| | | | | | | | | | | | | | | | ioctl(BLKGETSIZE) expects unsigned long (8 bytes on 64 bit environment). This is fixing fails in android.os.storage.StorageManagerIntegrationTest (in FrameworkCoreTests). To verify, install FrameworksCoreTests.apk and do: adb shell am instrument -r -w -e class android.os.storage.\ StorageManagerIntegrationTest#testMountSingleEncryptedObb \ com.android.frameworks.coretests/android.test.InstrumentationTestRunner Change-Id: Ib6d5c7490c02521c93f107c35ad0aac49f6a3f1a
* Added support for ext4 ASEC resizing.Daniel Rosenberg2014-06-101-0/+1
| | | | | | | | | ASECs formatted as ext4 can now be resized using vdc asec resize. Refactored some common code. Requires resize2fs. Change-Id: Ie78bb6015114a7bc4af42b16d1f299322ffc1e2a Signed-off-by: Daniel Rosenberg <drosen@google.com>
* Add in ext4 support for ASEC containersKenny Root2012-04-251-0/+1
| | | | | | | | | Now forward locked applications will be in ASEC containers both internal to the system and externally. This change adds support for putting applications in ext4-based ASECs. Change-Id: I8d6765b72dd2606e429c067b47a2dbcaa8bef37d
* vold: Bugfixes & cleanupsSan Mehat2010-03-131-2/+6
| | | | | | | | | | | | | - Fix issue where container-names > 64 bytes were getting truncated in the kernel. lo_name is only 64 bytes in length, so we now hash the container id via md5 - Add 'dump' command to dump loop and devicemapper status - Add 'debug' command to enable more detailed logging at runtime - Log vold IPC arguments (minus encryption keys) - Fix premature return from Loop::lookupActive() and friends Change-Id: I0e833261a445ce9dc1a8187e5501d27daba1ca76 Signed-off-by: San Mehat <san@google.com>

| | | | | | | | - Supports up to 4096 containers - Keys are now implemented - specifying a key of 'none' means no encryption. Otherwise, the key must be a string of 32 characters Signed-off-by: San Mehat <san@google.com>
