* 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
| | | | | | | | | The `std::string package` variable goes out of scope but the input_path variable is then used to access the memory as it's set to `c_str()`. This was detected via OpenBSD malloc's junk filling feature. Change-Id: Ic4b939347881b6ebebf71884e7e2272ce99510e2
* uncrypt: Suppress the compiler warnings on LP64.Tao Bao2015-12-091-10/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have the following warnings when compiling uncrypt on LP64 (e.g. aosp_angler-userdebug). bootable/recovery/uncrypt/uncrypt.cpp:77:53: warning: format specifies type 'long long' but the argument has type 'off64_t' (aka 'long') [-Wformat] ALOGE("error seeking to offset %lld: %s\n", offset, strerror(errno)); ~~~~ ^~~~~~ %ld bootable/recovery/uncrypt/uncrypt.cpp:84:54: warning: format specifies type 'long long' but the argument has type 'unsigned long' [-Wformat] ALOGE("error writing offset %lld: %s\n", (offset + written), strerror(errno)); ~~~~ ^~~~~~~~~~~~~~~~~~ %lu bootable/recovery/uncrypt/uncrypt.cpp:246:16: warning: comparison of integers of different signs: 'size_t' (aka 'unsigned long') and 'off_t' (aka 'long') [-Wsign-compare] while (pos < sb.st_size) { ~~~ ^ ~~~~~~~~~~ According to POSIX spec [1], we have: off_t and blksize_t shall be signed integer types; size_t shall be an unsigned integer type; blksize_t and size_t are no greater than the width of type long. And on Android, we always have a 64-bit st_size from stat(2) (//bionic/libc/include/sys/stat.h). Fix the type and add necessary casts to suppress the warnings.

* 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.

* Use unique_ptr and unique_fd to manager FDs.Tao Bao2015-08-101-16/+16
| | | | | | | | 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

| | | | | | Bug: 22534003 Change-Id: I2bc22418c416491da573875dce78daed24f2c046 (cherry picked from commit 6e9dda70cb00dd1f1948e071d7df7ca6e2bd8332)
* uncrypt: Write status when it reboots to factory resetTao Bao2015-06-101-7/+10
| | | | | | | | | When it reboots into recovery for a factory reset, it still needs to write the uncrypt status (-1) to the pipe. Bug: 21511893 (cherry picked from commit 2c2cae8a4a18b85043bb6260a59ac7d1589016bf) Change-Id: Ia5a75c5edf3afbd916153da1b4de4db2f00d0209
* 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. Bug: 20012567 Bug: 20949086 (cherry picked from commit 158e11d6738a751b754d09df7275add589c31191) Change-Id: I349f6d368a0d6f6ee4332831c4cd4075a47426ff

* uncrypt: Switch to C++Tao Bao2015-05-061-0/+465
Also apply some trivial changes like int -> bool and clean-ups. Change-Id: Ic55fc8b82d7e91b321f69d10175be23d5c04eb92
