* Create bootloader_message static library.Yabin Cui2016-06-301-10/+1
| | | | | | | | | | bootloader_messages merges bootloader_message_writer and bootloader.cpp, so we can use the same library to manage bootloader_message in normal boot and recovery mode. Bug: 29582118 Change-Id: I9efdf776ef8f02b53911ff43a518e035e0c29618
* uncrypt: split libbootloader_message_writer for reuse.Yabin Cui2016-04-081-1/+11
| | | | | | | | init and vold also need to write bootloader message, so split this function from uncrypt into a separate library. Bug: 27176738 Change-Id: If9b0887b4f6ffab6162d9cb47a6ceb7eedd60b4d
* move uncrypt from init.rc to uncrypt.rcTom Cherry2015-09-041-0/+2
| | | | | | | | | Move uncrypt from /init.rc to /system/etc/init/uncrypt.rc using the LOCAL_INIT_RC mechanism Bug 23186545 Change-Id: Ib8cb6dffd2212f524298279787fd557bc84aa7b9
* Use unique_ptr and unique_fd to manager FDs.Tao Bao2015-08-101-0/+2
| | | | | | | | Clean up leaky file descriptors in uncrypt/uncrypt.cpp. Add unique_fd for open() and unique_file for fopen() to close FDs on destruction. Bug: 21496020 Change-Id: I0174db0de9d5f59cd43b44757b8ef0f5912c91a2
* Separate uncrypt into two modesTao Bao2015-06-101-1/+1
| | | | | | | | | | | | | | | 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. Bug: 20012567 Bug: 20949086 (cherry picked from commit 158e11d6738a751b754d09df7275add589c31191) Change-Id: I349f6d368a0d6f6ee4332831c4cd4075a47426ff
* recovery: Switch to clangTao Bao2015-06-031-0/+2
| | | | | | And a few trival fixes to suppress warnings. Change-Id: I38734b5f4434643e85feab25f4807b46a45d8d65
* uncrypt: Switch to C++Tao Bao2015-05-061-1/+1
| | | | | | Also apply some trivial changes like int -> bool and clean-ups. Change-Id: Ic55fc8b82d7e91b321f69d10175be23d5c04eb92
* open misc device in write-only modeDoug Zongker2014-08-261-1/+1
| | | | | | | | | | Opening the misc block device in read-write mode runs afoul of SELinux, which keeps the wipe code from working. Fix. Also change various things to log to logcat so we can see them happening, for future debugging. Bug: 16715412 Change-Id: Ia14066f0a371cd605fcb544547b58a41acca70b9
* revert uncrypt back to dynamic linking, fix libsDoug Zongker2014-08-141-6/+1

* program to store unencrypted files in an encrypted filesystemDoug Zongker2014-01-161-0/+28
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
