* Allow uncrypt to work without socket communicationTianjie Xu2016-11-111-2/+18
| | | | | | | | | | | | | It was inconvenient to uncrypt a update package under adb shell because the uncrypt executable required a socket to start its job. Add a workaround to allow uncrypt executes without socket communication. Test: run uncrypt under adb shell, and the block map generates successfully Bug: 29906218 Change-Id: Ibc328b31636d925dc429ede8dcec7392a721dd53 (cherry picked from commit 28c1e5d3aa9610db6e141380b1435937fc7f07db)
* Verify wipe package when wiping A/B device in recovery.Yabin Cui2016-10-191-1/+18
| | | | | | | | | | | | | | | To increase the security of wiping A/B devices, let uncrypt write wipe package in misc partition. Then recovery verifies the wipe package before wiping the device. Based on the original cherrypick, this CL also has additional changes to address the LOG statements and libziparchive changes. Bug: 29159185 Test: Build and boot into recovery. Change-Id: I186691bab1928d3dc036bc5542abd64a81bc2168 (cherry picked from commit 6faf0265c9b58db2c15b53f6d29025629d52f882)
* Create bootloader_message static library.Yabin Cui2016-10-181-1/+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 (cherry picked from commit 2f272c0551f984e83bc5abaf240e0dddb38a3326)

* save uncrypt status to last_installTianjie Xu2016-09-131-0/+21
| | | | | | | | | | | Save the uncrypt time cost to /cache/recovery/uncrypt_status. Recovery reads the file and saves its contents to last_install. Bug: 31383361 Test: Tested on angler and uncrypt_time reports correctly. Change-Id: I5cd3f7b6ca069d69086d09acfea8fc4f1215c833 Merged-In: I5cd3f7b6ca069d69086d09acfea8fc4f1215c833

* | uncrypt: Communicate via /dev/socket/uncrypt.Tao Bao2016-03-031-79/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Retire pre-recovery service.Tao Bao2016-02-231-13/+1
|/ | | | | | | | | | The framework CL in [1] removes the use of "pre-recovery" service which is basically to trigger a reboot into the recovery. [1] commit e8a403d57c8ea540f8287cdaee8b90f0cf9626a3 Bug: 26830925 Change-Id: I131f31a228df59e4f9c3024b238bbdee0be2b157

* uncrypt: generate map file by renaming tmp file.Yabin Cui2016-02-011-75/+93
| | | | | | | | | Writing map file directly can break consistency in map file if it fails in the middle. Instead, we write a temporary file and rename the temporary file to map file. Bug: 26883096 Change-Id: I5e99e942e1b75e758af5f7a48f8a08a0b0041d6a
* uncrypt: avoid use-after-freeDaniel Micay2016-01-121-3/+4

* We can use fclose directly in std::unique_ptr.Elliott Hughes2015-11-131-5/+5
| | | | | | | | It turns out the standard explicitly states that if the pointer is null, the deleter function won't be called. So it doesn't matter that fclose(3) doesn't accept null. Change-Id: I10e6e0d62209ec03ac60e673edd46f32ba279a04
* 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 Bao2015-06-101-94/+91
| | | | | | | | | | | | | | | 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.
