* uncrypt: fix ioctl direction for F2FS_IOC_GET_PIN_FILEDevin Kim2018-09-121-1/+1
| | | | | | The direction should be set as READ, not WRITE Change-Id: Id695276f25c1d75bca3a02d87e4a59623e95cb00
* uncrypt: Depend on commonly used shared libs.Tao Bao2018-08-231-5/+7
| | | | | | | | | | | | We already have these shared libraries on device. And `uncrypt` doesn't need to be statically linked (it wasn't, even prior to this change). With this change, the size of uncrypt goes down from 139KiB to 33KiB (aosp_marlin-userdebug). Test: Build and flash on marlin. Trigger a factory reset (which calls `uncrypt` to set up the BCB).

* f2fs: support f2fs by setting unmovable bit for package fileJaegeuk Kim2018-03-221-4/+38
| | | | | | | | | | | | | | | This enables to use uncrypt for f2fs update-on-reboot. It requires kernel patch named: "f2fs: add an ioctl to disable GC for specific file" If any operation fails during uncrypt, please delete package file as soon as possible, and create the file again to move forward. IOWs, don't leave the package file for a long time. Bug: 70309376 Bug: 30170612 Change-Id: I3b4233e7da756f107be35364521699deaf2e7139 Signed-off-by: Jaegeuk Kim <jaegeuk@google.com>

* Revert "Revert "Move error_code.h into otautil.""Tao Bao2017-10-092-2/+2
| | | | | | | | | | | | | | | | This reverts commit 26436d6d6010d5323349af7e119ff8f34f85c40c to re-land "Move error_code.h into otautil.". This way it stops requiring relative path ".." in LOCAL_C_INCLUDES (uncrypt and edify). Soong doesn't accept non-local ".." in "local_include_dirs". This CL needs to land with device-specific module changes (e.g. adding the dependency on libotautil).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fstab settings of early-mounted partitions (e.g., /vendor) will be in kernel device tree. Switch to the new API to get the whole settings with those in device tree: fs_mgr_read_fstab_with_dt("/etc/recovery.fstab") The original default /fstab.{ro.hardware} might be moved to /vendor/etc/. or /odm/etc/. Use another new API to get the default fstab instead of using the hard-coded /fstab.{ro.hardware}. This API also includes the settings from device tree: fs_mgr_read_fstab_default() Bug: 35811655 Test: boot sailfish recovery Change-Id: Iaa56ac7f7b4c4dfc7180c65f03e9a37b94f1de09

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some conditions, ioctl(fd, FIBMAP, &block) returns block number 0.This is a failure to locate the actual block number of the update package and will result in an invalid block.map. This CL retries ioctl a few times if it returns block number as 0. Bug: 31632090 Test: On N9, uncrypt retries ioctl and produces the correct blockmap.

* | uncrypt: Communicate via /dev/socket/uncrypt.Tao Bao2016-03-032-79/+184
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We used to rely on files (e.g. /cache/recovery/command and /cache/recovery/uncrypt_status) to communicate between uncrypt and its caller (i.e. system_server). Since A/B devices may not have /cache partitions anymore, we switch to socket communication instead. We will keep the use of /cache/recovery/uncrypt_file to indicate the OTA package to be uncrypt'd though. Because there is existing logic in ShutdownThread.java that depends on the existence of the file to detect pending uncrypt works. This part won't affect A/B devices without /cache partitions, because such devices won't need uncrypt service (i.e the real de-encrypt work) anyway.

* uncrypt: remove O_SYNC to avoid time-out failuresJaegeuk Kim2015-11-041-1/+1
| | | | | | | | | | | This patch removes costly O_SYNC flag for encrypted block device. After writing whole decrypted blocks, fsync should guarantee their consistency from further power failures. This patch reduces the elapsed time significantly consumed by upgrading packages on an encrypted partition, so that it could avoid another time-out failures too.

* Separate uncrypt into two modesTao Bao2015-06-102-95/+92
| | | | | | | | | | | | | | | uncrypt needs to be triggered to prepare the OTA package before rebooting into the recovery. Separate uncrypt into two modes. In mode 1, it uncrypts the OTA package, but will not reboot the device. In mode 2, it wipes the /misc partition and reboots. Needs matching changes in frameworks/base, system/core and external/sepolicy to work properly.

* program to store unencrypted files in an encrypted filesystemDoug Zongker2014-01-162-0/+405
uncrypt can read a file on an encrypted filesystem and rewrite it to the same blocks on the underlying (unencrypted) block device. This destroys the contents of the file as far as the encrypted filesystem is concerned, but allows the data to be read without the encryption key if you know which blocks of the raw device to access. uncrypt produces a "block map" file which lists the blocks that contain the file. For unencrypted filesystem, uncrypt will produce the block map without touching the data. Bug: 12188746 Change-Id: Ib7259b9e14dac8af406796b429d58378a00c7c63
