Move crypt commands to a different listener in vold 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.

Add f2fs support for private volumes. 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.

CheckBattery.cpp \
Securely encrypt the master key Move all key management into vold Reuse vold's existing key management through the crypto footer to manage the device wide keys. Use ro.crypto.type flag to determine crypto type, which prevents any issues when running in block encrypted mode, as well as speeding up boot in block or no encryption. This is one of four changes to enable this functionality: https://android-review.googlesource.com/#/c/148586/ https://android-review.googlesource.com/#/c/148604/ https://android-review.googlesource.com/#/c/148606/ https://android-review.googlesource.com/#/c/148607/ Bug: 18151196 Change-Id: I3c68691717a61b5e1df76423ca0c02baff0dab98

VoldUtil.c \
Checkpoint of better dynamic device support. This is the first in a series of changes that are designed to introduce better support for dynamic block devices. It starts by defining a new Volume object which represents a storage endpoint that knows how to mount, unmount, and format itself. This could be a filesystem directly on a partition, or it could be an emulated FUSE filesystem, an ASEC, or an OBB. These new volumes can be "stacked" so that unmounting a volume will also unmount any volumes stacked above it. Volumes that provide shared storage can also be asked to present themselves (through bind mounts) into user-specific mount areas. This change also adds a Disk class which is created based on block kernel netlink events. Instead of waiting for partition events from the kernel, it uses gptfdisk to read partition details and creates the relevant Volume objects. Change-Id: I0e8bc1f8f9dcb24405f5e795c0658998e22ae2f7

cryptfs.c \
Disk.cpp \
VolumeBase.cpp \
PublicVolume.cpp \
Support for private (adopted) volumes. This adds support for private volumes which is just a filesystem wrapped in a dm-crypt layer. For now we're using the exact same configuration as internal encryption (aes-cbc-essiv:sha256), but we don't store any key material on the removable media. Instead, we store the key on internal storage, and use the GPT partition GUID to identify which key should be used. This means that private external storage is effectively as secure as the internal storage of the device. That is, if the internal storage is encrypted, then our external storage key is also encrypted. When partitioning disks, we now support a "private" mode which has a PrivateVolume partition, and a currently unused 16MB metadata partition reserved for future use. It also supports a "mixed" mode which creates both a PublicVolume and PrivateVolume on the same disk. Mixed mode is currently experimental. For now, just add ext4 support to PrivateVolume; we'll look at f2fs in a future change. Add VolumeBase lifecycle for setting up crypto mappings, and extract blkid logic into shared method. Sprinkle some more "static" around the cryptfs code to improve invariants. Bug: 19993667 Change-Id: Ibd1df6250735b706959a1eb9d9f7219ea85912a0

EmulatedVolume.cpp \
Utils.cpp \
Migrate primary external storage. When requested, kick off a thread that will migrate storage contents between two locations. This is performed in several steps that also interact with the framework: 1. Take old and new volumes offline during migration 2. Wipe new location clean (10% of progress) 3. Copy files from old to new (60% of progress) 4. Inform framework that move was successful so it can persist 5. Wipe old location clean (15% of progress) Derives a hacky progress estimate by using a rough proxy of free disk space changes while a cp/rm is taking place. Add new internal path for direct access to volumes to bypass any FUSE emulation overhead, and send it to framework. Remove mutex around various exec calls since setexeccon() is already per-thread.

MoveTask.cpp \
Initial pass at storage benchmarks. 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.

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

Don't try to encrypt in place a filesystem that is too large and return proper errors If the already existing filesystem encompasses the entire /data partition and does not leave the last 16 Kbytes for the crypto footer, refuse to do encrypt in place and return an error.

Have vold grab a partial wakelock when encrypting The Progress bar UI grabs a full wakelock when encrypting, but we've seen a case where it looks like the progress bar UI crashes, and the wakelock is lost, and then all hell breaks loose. The enablecrypto command has a lot of work to do, and it will take some time, so it should grab a wakelock to ensure it can finish without being interrupted and put to sleep. It grabs a partial wake lock, as it doesn't need the screen to be on to do its work. If the UI wants to keep it on, it should also grab a full wakelock, which it does. If the UI crashes, the screen may turn off, but the encryption will keep going, and vold will reboot the device when it's done. Change-Id: I51d3a72b8c77383044a3facb1604c1ee510733ae

Fix alignment of buffer used for dm_ioctl. Since the dm_ioctl struct was being allocated on the stack as a large character array, it was getting character alignment rather than the proper alignment for the struct.

Adding support of dm-req-crypt Currently Android provides disk encryption support using dm-crypt which is based on bios. dm-crypt uses 512 bytes packet size for crypto operations. While 512 bytes size packet is ok for SW based disk encryption, it is inefficient for HW based crypto engines. dm-req-crypt is similar to dm-crypt except it uses block requests rathe bios for crypto operations. block requests when unpacked carries data upto 512KB. Hence, HW based crypto engine can be used more efficiently. Also move create disk encryption key before framework start as HW based disk encryption creates key in secure side. Key creation can take sometime to create the key securely. If framework is started before creating the key, it is possible that framework requests service from secure side. Secure side can serve mostly one request at a time. Secure side may reject framework request if key creation request is still going on. This may cause problem in the system b/17475056 Enable hardware crypto for userdata encryption Change-Id: I5480ab72a37c02532218a18faaba598a824589fd Signed-off-by: Iliyan Malchev <malchev@google.com>

Change key derivation to scrypt scrypt is a sequential memory-hard key derivation algorithm that makes it more difficult for adversaries to brute force passwords using specialized equipment. See http://www.tarsnap.com/scrypt/scrypt.pdf for more details of the algorithm. This adds support for initializing disk encryption using scrypt and upgrading from the previous PBKDF2 algorithm.

Changes to encryption to work with the new filesystem manager The new filesystem manager is in charge of mounting the block devices now, removing much of the knowledge from init.<device>.rc. This also let us clean up some init code dealing with encryption, so this change updates vold to work with that. More cleanup is possible, but the main goal of the filesystem manager was to enable e2fsck, not a full cleanup of encryption. Change-Id: I00ea80a923d14770ed8fdd190e8840be195f8514
