2019-01-17Fix potential size overflow in blockimg.cppxunchang1-3/+5
Switch to 64 bit integers since the size of the entire src/tgt images may not fit in size_t of ILP32. There are other theoretical overflow cases in memory allocation and I/O functions. However, they reside within a single transfer command and are less likely to happen. I will evaluate and address them in separate cls.

2019-01-12Create stash dir recursively.Yifan Hong1-1/+2
When applying an OTA package onto the device in OTA mode, if the recovery logs haven't been viewed, there is a chance that /cache/recovery does not exist. Then, stash creation will fail. Create stash directories recursively to avoid this error. Test: without /cache/recovery, sideload the OTA on cuttlefish Change-Id: I5cc01a067d866476a3594e795dcb5b15649e817b

2018-08-06Add an updater function to compute hash treeTianjie Xu1-18/+123
The new command is part of the transfer.list and allows us to compute the hash tree on non-ab devices. The required arguments for the hash_tree computation are: hash_tree_ranges source_ranges hash_algorithm salt_hex root_hash Bug: 25170618 Test: unit tests pass; run simulator with compute_hash_tree Change-Id: I8ff0d582cc8adabb8a060db7845f38b35b28e62c
2018-07-13applypatch: Consolidate CacheSizeCheck() and MakeFreeSpaceOnCache().Tao Bao1-3/+3
They are doing exactly the same thing, except for the slightly different error return value (1 vs -1). int CacheSizeCheck(size_t bytes); int MakeFreeSpaceOnCache(size_t bytes_needed); This CL consolidates the two functions and uses bool as its return type. // Checks whether /cache partition has at least 'bytes'-byte free space. Returns true immediately // if so. Otherwise, it will try to free some space by removing older logs, checks again and // returns the checking result. bool CheckAndFreeSpaceOnCache(size_t bytes); Test: Run recovery_unit_test and recovery_component_test on marlin.

2018-07-07updater: Add ABORT command.Tao Bao1-0/+7
This will be used for testing purpose only, replacing the previously used "fail", to intentionally abort an update. As we're separating the logic between commands parsing and execution, "abort" needs to be considered as a valid command during the parsing. Test: recovery_unit_test and recovery_component_test on marlin. Change-Id: I47c41c423e62c41cc8515fd92f3c5959be08da02
2018-07-03No longer print hash for stashed blocks during verification of retryTianjie Xu1-1/+3
During block verification, load stash reads from the source blocks on the device instead of the stashed files. And for interrupted update, it's pretty common that the source blocks has already been overwritten by subsequent commands. In that case the hash printing is mostly useless. Moreover we should have already printed the hash when the first update failed. Bug: 80241799 Test: Unit tests pass. No longer prints mismatching stashed source blocks on retry. Change-Id: I4effe684280b0325199f6cc4b2cc26e91295c2d7
2018-06-18updater: Defer the creation of the new data writer.Tao Bao1-24/+24
This avoids leaving the created new data writer thread unjoined, in the presence of transfer list parsing errors, or the early exit case on `total_blocks == 0`. Also fix a minor issue when dumping the errno on pthread_create error (pthread_create returns the error number, as opposed to setting errno). Test: Run recovery_component_test on marlin.

2018-06-05updater: Replace the reference arguments with pointers.Tao Bao1-102/+101
As suggested by the style guide (https://google.github.io/styleguide/cppguide.html#Reference_Arguments), all parameters passed by reference must be labeled const. This CL moves most of the non-const references in blockimg.cpp to pointers, except for the CommandParameters& parameter in PerformCommand* functions, which will be handled in separate CLs. Test: mmma -j bootable/recovery Test: Run recovery_component_test on marlin. Change-Id: I84299208e9a1699f5381fb2228d4120f0c8dacb3
2018-06-04tests: Add ResumableUpdaterTest.Tao Bao1-0/+1
This is a stress test that instantiates multiple testcases that interrupt a BBOTA update at every transfer command. Each testcase asserts the last_command_file after the interruption, verifies the update resumability, then resumes the update and asserts the updated image. The transfer list in the testcase covers most of the transfer commands (stash/free/move/bsdiff/zero/new), as well as some special pattern like having duplicate stash ids. This CL also addresses one issue in the updater code, by resetting the stash_map before each run. The stash map should be valid only per block_image_verify/block_image_update run. Having leftover may cause issue in subsequent runs, in particular when calling block_image_verify after a previous run of block_image_{update,verify}. Test: Run recovery_component_test on marlin. Change-Id: I6f9a0368d194a754ce41a9c9819c6d5be2657248
2018-05-31updater: Drop the 'blocks' parameter in LoadStash().Tao Bao1-15/+8
None of the callers actually uses the value. (Even in the earlier versions, e.g. the one in M, the value wasn't used either.) Test: Run recovery_component_test on marlin. Change-Id: I53e61a1afa211f71a200889ed3aa4046763b46ea
2018-05-26updater: Add Commmand class to manage BBOTA commands.Tao Bao1-63/+54
Move the commands map parsing out of PerformBlockImageUpdate(), as this can be done more easily by the caller. The goal (not done in this CL) is to decouple command parsing logic from the performers. This allows (a) focusing on the command logic in the performer; and (b) extending BBOTA commands syntax separately. Test: Run recovery_unit_test and recovery_component_test. Change-Id: Ife202398a7660b152d84a3ba17b90f93d19c55f2
2018-05-22updater: Use a bool to indicate if allowed to skip a command.Tao Bao1-22/+17

2018-05-21updater: Clean up the header lines computation.Tao Bao1-6/+4

2018-05-16Last command file should be updated after a command finishesTianjie Xu1-11/+7
The last command file has the last executed stash command by convention. So we should update the file after we actually finishes executing the command; instead of after loading src/tgt. Bug: 79756267 Test: unit tests pass Change-Id: I4535b5836e7eb13b3abe3d02f9f362ec5e9ec969
2018-05-08updater: Fix an issue when resuming an update.Tao Bao1-3/+6
We cannot skip "new" commands while resuming an update with last_command_file, because they read in the data sequentially from the package. Bug: 69858743 Test: Interrupt an update that has new commands. Check the update log. Change-Id: I05fb67246f5ea3ba2a0f78f10255c0d9b0bc2f5a
2018-05-08updater: Skip an updated partition on retry.Tao Bao1-39/+77
Prior to the change, the BBOTA updater would try to re-run all the commands for a given partition on retry, including creating stashes according to the list of commands. This could fail a retry when the previous update had moved on to next stage, with leftovers in /cache. This CL creates a marker on /cache upon successfully updating a partition. The update commands will be skipped when trying to apply updates on an updated partition. Note that the marker is expected to be removed while doing a normal boot (in particular, handled by RecoverySystem#handleAftermath). If that didn't happen, the updater would also remove the marker before starting next fresh update. Alternatively, we can achieve the same goal by changing the OTA script, which needs to additionally compare the checksum against the target build. For example, range_sha1("/system", "ranges") == SHA1_of_updated_system || block_image_update("/system"); The downside is that we need to pay that cost on each install, as the edify script doesn't support caching the result in a variable. Bug: 79165963 Test: Simulate the process on device (by triggering a reboot while updating /vendor). Check the update log and result. Change-Id: I731031fa336133e1221b33edfc469969706e8091
2018-04-26Rename CacheLocation to Paths.Tao Bao1-16/+12
We have a general need for overriding more paths (e.g. "/tmp"), mostly for testing purpose. Rename CacheLocation to Paths, and use that to manage TEMPORARY_{INSTALL,LOG}_FILE. Test: mmma -j bootable/recovery Test: recovery_component_test Change-Id: Ia8ce8e5695df37ca434f13ac4d3206de1e8e9396

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. Change-Id: Ib60ba1e3c6d111d9f33097759b17dbcef97a37bf
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
2017-11-10applypatch: Change the patch parameter to const Value& in Apply{BSDiff,Image}Patch.Tao Bao1-2/+2

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

2017-04-03Change 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.

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.

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.

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.

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.

2015-05-28Handle BLKDISCARD failuresSami Tolvanen1-2/+1
In the block updater, if BLKDISCARD fails, the error is silently ignored and some of the blocks may not be erased. This means the target partition will have inconsistent contents. If the ioctl fails, return an error and abort the update. Bug: 20614277 Change-Id: I33867ba9337c514de8ffae59f28584b285324067

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.
