2015-05-29uncrypt: Write status when it reboots to factory resetTao Bao1-7/+10
When it reboots into recovery for a factory reset, it still needs to write the uncrypt status (-1) to the pipe. Bug: 21511893 Change-Id: I1a725820f1e1875146e49b5a6f28af2fbf284fc7
2015-05-28Separate uncrypt into two modesTao Bao2-98/+95
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 Change-Id: I14d25cb62770dd405cb56824d05d649c3a94f315
2015-05-06uncrypt: Switch to C++Tao Bao2-42/+40
Also apply some trivial changes like int -> bool and clean-ups. Change-Id: I5c6c42d34965305c394f4f2de78487bd1174992a (cherry picked from commit 381f455cac0905b023dde79625b06c27b6165dd0)
2015-05-06uncrypt: package on non-data partition should follow the right pathTao Bao1-20/+41
Fix the accidental change of behavior in [1]. OTA packages not on /data partition should still go through the path that has validity checks and wipe_misc() steps. [1]: commit eaf33654c1817bd665831a13c5bd0c04daabee02. Change-Id: I3e86e19f06603bfe6ecc691c9aa66a8a8a79c5fb (cherry picked from commit fb4ccef1df4f0bd8fa830c750f2970dd2df9e51b)

2014-12-11Add O_CREAT option for openSungmin Choi1-2/+10
Factory reset fails if there is no file, for example, RECOVERY_COMMAND_FILE_TMP. So create file as adding O_CREAT option if it does not exist. error log: --------- beginning of crash 12-10 02:35:17.190 3059 3059 F libc : Fatal signal 11 (SIGSEGV), code 1, fault addr 0x30 in tid 3059 (uncrypt) 12-10 02:35:17.296 766 1528 W NativeCrashListener: Couldn't find ProcessRecord for pid 3059 12-10 02:35:17.296 191 191 I DEBUG : *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** 12-10 02:35:17.296 191 191 E DEBUG : AM write failure (32 / Broken pipe) 12-10 02:35:17.296 191 191 I DEBUG : Build fingerprint: 'Android/aosp_hammerhead/hammerhead:5.1/LMP/hopemini12052127:userdebug/test-keys' 12-10 02:35:17.296 191 191 I DEBUG : Revision: '10' 12-10 02:35:17.297 191 191 I DEBUG : ABI: 'arm' 12-10 02:35:17.297 191 191 I DEBUG : pid: 3059, tid: 3059, name: uncrypt >>> /system/bin/uncrypt <<< 12-10 02:35:17.297 191 191 I DEBUG : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x30 12-10 02:35:17.302 191 191 I DEBUG : r0 00000001 r1 be94b690 r2 fffffe90 r3 b6fdbf7c 12-10 02:35:17.302 191 191 I DEBUG : r4 00000000 r5 00000000 r6 b6fd8ca4 r7 be94b67c 12-10 02:35:17.302 191 191 I DEBUG : r8 00000000 r9 ffffffff sl b6ff582b fp be94b68d 12-10 02:35:17.302 191 191 I DEBUG : ip b6fcfd08 sp be94b648 lr b6f98fe5 pc b6f98fe4 cpsr 20070030 12-10 02:35:17.303 191 191 I DEBUG : 12-10 02:35:17.303 191 191 I DEBUG : backtrace: 12-10 02:35:17.303 191 191 I DEBUG : #00 pc 00032fe4 /system/lib/libc.so (fputs+29) 12-10 02:35:17.303 191 191 I DEBUG : #01 pc 000016a1 /system/bin/uncrypt 12-10 02:35:17.303 191 191 I DEBUG : #02 pc 0000114b /system/bin/uncrypt 12-10 02:35:17.303 191 191 I DEBUG : #03 pc 00012df5 /system/lib/libc.so (__libc_init+44) 12-10 02:35:17.303 191 191 I DEBUG : #04 pc 000013cc /system/bin/uncrypt 12-10 02:35:17.325 191 191 I DEBUG : 12-10 02:35:17.325 191 191 I DEBUG : Tombstone written to: /data/tombstones/tombstone_00 Bug: 18709330 Change-Id: Ib5dccdd366e829049938a188ea5f98d9e4e282db

Always create the block map for packages on /data; don't only look at the encryptable/encrypted flags. Bug: 17395453 Change-Id: Iaa7643a32898328277841e324305b9419a9e071c
2014-08-26open misc device in write-only modeDoug Zongker2-19/+27
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
2014-08-19clear BCB in misc partition before rebootingDoug Zongker1-3/+43
Something is leaving behind wipe commands in the BCB area of the /misc partition. We don't know what is doing that. It should always be safe to zero out that area from uncrypt, though (because if uncrypt is running then it's got the command we want in the recovery command file rather than the BCB).

2014-02-14Fix a crash when going into recovery mode.Maxim Siniavine1-1/+6
When going into recovery mode withoug recovery command file present, uncrypt crashes and the device gets stuck and eventually shuts down. Check that the command file is present before trying to read from it. Change-Id: If0192d597032be0067738e437188d92993ce56f7
2014-01-16program to store unencrypted files in an encrypted filesystemDoug Zongker2-0/+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
