2019-03-23updater: Allow devices to suppress BLKDISCARDandi341-0/+2
* On some devices TRIM is disabled for security reasons. Don't fail flashing the ROM because discard isn't possible in this case. Change-Id: I044619c3e0b01a496d967ef136501d0190240ad4
2018-02-28Add a singleton CacheLocation to replace the hard coded locationsTianjie Xu1-4/+5
This class allows us to set the following locations dynamically: cache_temp_source, last_command_file, stash_directory_base. In the updater's main function, we reset the values of these variables to their default locations in /cache; while we can set them to temp files in unit tests or host simulation. Test: unit tests pass Change-Id: I528652650caa41373617ab055d41b1f1a4ec0f87
2018-02-28Fix the behavior of undefined commands in BlockImageVerifyTianjie Xu1-2/+4
In BlockImageVerify some commands are undefined, e.g. "erase", "new", "zero". And we should not error out if the corresponding function pointer of these commands is null; otherwise we will fail the verification. The old code is: if (cmd->f != nullptr && cmd->f(params) == -1) return false; In the last_command_file change the logic was wrongly modified to if (cmd->f == nullptr) return false; ... if (cmd->f(params) == -1) return false; Test: sideload an incremental OTA twice on bullhead Change-Id: I2561c365badb850da0e416629ccd61f0df7da5d7
2018-02-07Log the last command to cacheTianjie Xu1-9/+172
When performing an update, save the index and cmdline of the current command into the last command file if this command writes to the stash either explicitly of implicitly. This mitigates the overhead to update the last command file for every command. I ran a simple test on angler and the time to update 1000 times is ~2.3 seconds. Upon resuming an update, read the saved index first; then 1. In verification mode, check if all commands before the saved index have already produced the expected target blocks. If not, delete the last command file so that we will later resume the update from the start of the transfer list. 2. In update mode, skip all commands before the saved index. Therefore, we can avoid deleting stashes with duplicate id unintentionally; and also speed up the update. If an update succeeds or is unresumable, delete the last command file. Bug: 69858743 Test: Unittest passed, apply a failed update with invalid cmd on angler and check the last_command content, apply a failed update with invalid source hash and last_command is deleted.

2018-01-29Avoid overwrite of the error message in AbortFnTianjie Xu1-9/+9
The AbortFn() used to overwrite the error message, hiding the real failure reported in ErrorAbort(). And we will miss the failure in the script patterns like 'blockimageupdate() || abort()' We will ensure there's one line break at the end of ErrorAbort's error message; and append to the existing error message when calling abort(). Test: Message from ErrorAbort shows up in the log Change-Id: I3aebd06629c5129330250c7fe5e8cdead2ae85bc

2017-11-07otautil: Remove the aborts in RangeSet::Parse().Tao Bao1-1/+19
We used to CHECK and abort on parsing errors. While it works fine for the updater use case (because recovery starts updater in a forked process and collects the process exit code), it's difficult for other clients to use RangeSet as a library (e.g. update_verifier). This CL switches the aborts to returning empty RangeSet instead. Callers need to check the parsing results explicitly. The CL also separates RangeSet::PushBack() into a function, and moves SortedRangeSet::Clear() into RangeSet. Test: recovery_unit_test Test: Sideload an OTA package with the new updater on angler. Test: Sideload an OTA package with injected range string errors. The updater aborts from the explicit checks. Change-Id: If2b7f6f41dc93af917a21c7877a83e98dc3fd016
2017-10-20Finish the new data receiver when update failsTianjie Xu1-16/+41
The thread to receive new data may still be alive after we exit PerformBlockImageUpdate() upon failures. This caused memory corruption when we run the unittest repeatedly. Set the receiver_available flag to false and make sure the receiver exits when the update fails. Bug: 65430057 Test: unittests passed with tsan Change-Id: Icb232d13fb96c78262249ffbd29cdbe5b77f1fce

2017-07-22Fix a case when brotli writer fails to write last few blocks of dataTianjie Xu1-94/+81
receive_new_data may exit too early if the zip processor has sent all the raw data. As a result, the last few 'new' commands will fail even though the brotli decoder has more output in its buffer. Restruct the code so that 'NewThreadInfo' owns the decoder state solely; and receive_brotli_new_data is responsible for the decompression. Also reduce the test data size to 100 blocks to avoid the test timeout. Bug: 63802629 Test: recovery_component_test. on bullhead, apply full updates with and w/o brotli compressed entries, apply an incremental update.

2017-07-08Add support to decompress brotli compressed new dataTianjie Xu1-32/+143
Add a new writer that can decode the brotli-compressed system/vendor new data stored in the OTA zip. Brotli generally gives better compression rate at the cost of slightly increased time consumption. The patch.dat is already compressed by BZ; so there's no point to further compress it. For the given 1.9G bullhead system image: Size: 875M -> 787M; ~10% reduction of package size. Time: 147s -> 153s; ~4% increase of the block_image_update execution time. (I guess I/O takes much longer time than decompression.) Also it takes 4 minutes to compress the system image on my local machine, 3 more minutes than zip. Test: recovery tests pass && apply a full OTA with brotli compressed system/vendor.new.dat on bullhead Change-Id: I232335ebf662a9c55579ca073ad45265700a621e
2017-05-24Retry the update if ApplyBSDiffPatch | ApplyImagePatch failsTianjie Xu1-0/+2
We have seen one case when bspatch failed likely due to patch corruption. Since the package has passed verification before, we want to reboot and retry the patch command again since there's no alternative for users. We won't delete the stash before reboot, and the src has passed SHA1 check. If there's an error on the patch, it will fail the package verification during retry. Bug: 37855643 Test: angler reboots and retries the update when bspatch fails. Change-Id: I2ebac9621bd1f0649bb301b9a28a0dd079ed4e1d
2017-04-08Abort the update if there's not enough new dataTianjie Xu1-4/+26
Right now the update stuck in a deadlock if there's less new data than expection. Add some checkers and abort the update if such case happens. Also add a corresponding test. Bug: 36787146 Test: update aborts correctly on bullhead && recovery_component_test passes Change-Id: I914e4a2a4cf157b99ef2fc65bd21c6981e38ca47
2017-04-03Change the internal representation in RangeSet.Tao Bao1-205/+187
This CL makes the following changes to RangeSet: - Uses std::pair<size_t, size_t> to represent a Range; - Uses std::vector<Range> to represent a RangeSet; - Provides const iterators (forward and reverse); - Provides const accessor; - 'blocks()' returns the number of blocks (formerly 'size'); - 'size()' returns the number of Range's (formerly 'count').

2017-03-31updater: Keep the parsed parameters in std::unique_ptr.Tao Bao1-160/+157

2017-03-31Move parse_range() and range_overlaps() into RangeSet.Tao Bao1-110/+18
Also move RangeSet into a header file to make it testable, and add unit tests. In RangeSet::Parse() (the former parse_range()), use libbase logging to do assertions. This has the same effect as the previous exit(EXIT_FAILURE) to terminate the updater process and abort an update. The difference lies in the exit status code (i.e. WEXITSTATUS(status) in install.cpp), which changes from 1 (i.e. EXIT_FAILURE) to 0. Test: recovery_unit_test Test: Apply an incremental update with the new updater. Change-Id: Ie8393c78b0d8ae0fd5f0ca0646d871308d71fff0

LOG(INFO) already appends a newline. Don't print redundant newline. Test: No extra blank lines when calling ui_print(). And on-screen UI shows the same. Change-Id: I74e9a8504a7146a6cb3dae02fe2406d0dd54069b
2017-03-29updater: Move RangeSinkWrite into RangeSinkState.Tao Bao1-164/+146

2017-03-28applypatch: Change the ssize_t length parameters to size_t.Tao Bao1-41/+40
Mostly for applypatch family APIs like ApplyBSDiffPatch() and ApplyImagePatch(). Changing to size_t doesn't indicate they would necessarily work with very large size_t (e.g. > ssize_t), just similar to write(2). But otherwise accepting negative length doesn't make much sense. Also change the return type of SinkFn from ssize_t to size_t. Callers tell a successful sink by comparing the number of written bytes against the desired value. Negative return values like -1 are not needed. This also makes it consistent with bsdiff::bspatch interface. Test: recovery_component_test Test: Apply an incremental with the new updater. Change-Id: I7ff1615203a5c9854134f75d019e266f4ea6e714
2017-03-28updater: Clean up LoadSrcTgtVersion2().Tao Bao1-146/+143
Rename to LoadSourceBlocks() by moving the target blocks parsing part into the caller. This allows detecting whether the target blocks have already had the expected data before loading the source blocks. It doesn't affect anything when applying an update package for the first time, but it skips loading the unneeded source blocks when resuming an update. It additionally avoids unnecessarily dumping the "corrupt" source/stash blocks when resuming an update. Bug: 33694730 Test: Apply an incremental update with the new updater. Test: Resume an incremental update with the new updater. Change-Id: I794fd0d1045be7b3b7f8619285dc0dade01398d0
2017-03-24updater: Remove some redundant arguments.Tao Bao1-78/+65
Clean up a few functions that take CommandParameters& as the first parameter. We don't need to take duplicate arguments if they always come from CommandParameters. This redundancy came from the point we replaced strtok()s (commit baad2d454dc07ce916442987a2908a93fe6ae298). Test: Apply an incremental update with the new updater.

2017-03-22Fix the permission of stashed blocks created by updaterTianjie Xu1-0/+12
Our updater created the stashes with root permission. This causes an access denial when the RecoverySystem service tries to clean up these blocks after a failing update. As a result, the subsequent OTA updates may fail due to insufficient cache space.

2017-03-13Print SHA-1 in hex for corrupted blocksTianjie Xu1-3/+140
It will be helpful for debug if we know which blocks are corrupted after a verification failure.

2016-04-27updater: Don't zero out CommandParameters with memset(3).Tao Bao1-2/+1
[1] switched a few things to android::base::unique_fd including CommandParameters.fd. However, we were using memset(3) to zero out the struct, which effectively assigned unique_fd(0) to fd. When it called fd.reset(), file descriptor 0 was unintentionally closed. When FD 0 was later reassigned via open(2), it led to lseek(2) errors: "Bad file descriptor". This CL switches to using braced-init (i.e. '= {}') instead, so that the default constructor unique_fd(-1) would be called.

2016-03-25Skip stashing source blocks in verify modeTianjie Xu1-8/+46
Currently block_image_verify() stashes source blocks to /cache and in some case triggers I/O errors. To avoid this risk, We create a map from the hash value to the source blocks' range_set. When executing stash command in verify mode, source range is saved but block contents aren't stashed. And load_stash could get its value from either the stashed file from the previous update, or the contents on the source partition specified by the saved range.

2015-04-17Don't remove existing explicitly stashed blocksSami Tolvanen1-10/+28
When automatically stashing overlapping blocks, should the stash file already exist due to an explicit stash command, it's not safe to remove the stash file after the command has completed. Note that it is safe to assume that the stash file will remain in place during the execution of the next command, so we don't have take other measures to preserve overlapping blocks. The stash file itself will be removed by a free command when it's no longer needed. Bug: 20297065 Change-Id: I8ff1a798b94086adff183c5aac03260eb947ae2c

2015-01-30Support resuming block based OTAsSami Tolvanen1-346/+1460
Add support for transfer list version 3, which allows us to verify the status of each command and resume an interrupted block based OTA update. Notes on the changes: - Move the previous BlockImageUpdateFn to a shorter and reusable PerformBlockImageUpdate, which can be used also in BlockImageVerifyFn for verification. - Split individual transfer list commands into separate functions with unified parameters for clarity, and use a hash table to locate them during execution. - Move common block reading and writing to ReadBlocks and WriteBlocks to reduce code duplication, and rename the readblock and writeblock to less confusing read_all and write_all. The coding style of the new functions follows the existing style in the updater/edify code.

2014-09-26support for version 2 of block image diffsDoug Zongker1-45/+209
In version 2 of block image diffs, we support a new command to load data from the image and store it in the "stash table" and then subsequently use entries in the stash table to fill in missing bits of source data we're not allowed to read when doing move/bsdiff/imgdiff commands. This leads to smaller update packages because we can break cycles in the ordering of how pieces are updated by storing data away and using it later, rather than not using the data as input to the patch system at all. This comes at the cost of the RAM or scratch disk needed to store the data. The implementation is backwards compatible; it can still handle the existing version 1 of the transfer file format.
