2018-08-06Add an updater function to compute hash treeTianjie Xu1-0/+1
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
2018-07-30recovery: Add ability to interrupt UIJerry Zhang1-1/+38
Normally calling a UI method will block indefinitely until the UI is actually used. This creates a method to interrupt the UI, causing waitKey to return -2. This in turn, will cause ShowMenu to return -2. This allows switching between recovery and fastbootd via usb commands. Test: adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test Bug: 78793464 Change-Id: I4c6c9aa18d79070877841a5c9818acf723fa6096
2018-07-17Fix the arguments passed to getopt_long(3).Tao Bao1-0/+10
The getopt_long(3) implementation in Android (upstream freebsd) expects a null-terminated array while parsing long options with required args. if (long_options[match].has_arg == required_argument) { optarg = nargv[optind++]; } ... if (long_options[match].has_arg == required_argument && optarg == NULL) { return (BADARG); } This seems to make sense in practice, as getopt(3) takes the first two arguments of argc and argv that are "as passed to the main() function on program invocation", and both of C and C++ spec say "the value of argv[argc] shall be 0". Prior to the CL, we may run into undefined behavior on malformed input command line (e.g. missing arg for an option that requires one). This CL fixes the issue by always appending a nullptr to the argument list (but without counting that into argc). Test: Build and boot into recovery with commands. Change-Id: Ic6c37548f4db2f30aeabd40f387ca916eeca5392
2018-07-12tests: Clean up the temporary dirs post-run.Tao Bao2-21/+22
TemporaryDir only deletes empty dirs (not done by its dtor because it tries to keep the temporary files available on error exit). Also change FreeCacheTest::MockFreeSpaceChecker to be static. Test: Run recovery_unit_test on marlin. Check /data/local/tmp post-run. Change-Id: I1bd54eb840e3094b4f22ee84c059eec2998773bf
2018-07-12applypatch: Fix the return type of FreeSpaceForFile().Tao Bao1-6/+18
Prior to this CL, FreeSpaceForFile() was returning `size_t`, which may overflow on ILP32 when called on a partition with 4GiB+ free space. Additionally, it was returning static_cast<size_t>(-1) on error, but the caller in freecache.cpp didn't check for that. This CL changes its return type to `int64_t`, and moves the function into freecache.cpp since there's no external caller. Test: Run recovery_unit_test on marlin. Test: Code search shows no external user of FreeSpaceForFile(). Change-Id: I00f501a057726e1f1ab69f367c46c77b30f2d774
2018-07-10applypatch: Restrict applypatch_check to eMMC targets.Tao Bao1-85/+47
Also fix an error-pone behavior in previous code when verifying an eMMC target. As long as it loads the partition content successfully according to the SHAs embedded in the filename, it shouldn't further check against the SHAs given in the second argument. Because the loaded contents relate to a specific partition size. For example: apply_patch_check( "EMMC:/boot.img:src_size:src_hash:tgt_size:tgt_hash", "src_hash"); Assume "/boot.img" already has the desired hash of "tgt_hash", the previous code would give wrong verification result. The issue can be addressed by additionally listing "tgt_hash" as one of the desired SHAs (or by applying this CL). Bug: 110106408 Test: Run recovery_unit_test and recovery_component_test on marlin. Change-Id: I8daafdbecd083f687e24d563ab089caa25667633
2018-07-07updater: Add ABORT command.Tao Bao1-0/+24
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
2018-07-06tests: Split unit tests out of component/applypatch_test.cpp.Tao Bao1-0/+303

2018-06-25updater: Check the number of args in Command::Parse.Tao Bao1-0/+25
Additionally checks for excess args when parsing ERASE, FREE, NEW, STASH and ZERO. Note that the check for MOVE, BSDIFF, IMGDIFF has been covered in Command::ParseTargetInfoAndSourceInfo. Test: Run recovery_unit_test on marlin. Change-Id: Ic8bc9b7a8dcf98f1f8db2e259607564508726857
2018-06-25updater: Add Command parsing codes.Tao Bao1-0/+275
The added codes are not used in the updater yet. The switch will happen in subsequent CLs. Test: Run recovery_unit_test and recovery_component_test on marlin. Change-Id: I1ae8a233280f02c2171b43ef028bdccdacb39c59
2018-06-14tests: Skip ScreenRecoveryUITest on gr_init failure.Tao Bao1-1/+38
It addresses the ScreenRecoveryUITest failures on gce targets which don't have any graphics backend. Probing for all backend devices in tests could work, but would duplicate codes. This CL relies on the result of gr_init(). As a side effect, it may give false negatives if gr_init() is supposed to work but silently broken. But such issues are beyond ScreenRecoveryUITest's concern, which should be captured by the tests for minui or graphics backends instead. Fixes: 79616356 Test: Run recovery_unit_test on marlin. Test: Run recovery_unit_test on gce. Change-Id: I121aacc61c8a614447509506057ecfd8d86163e4
2018-06-06ui: join only if joinable.Tao Bao1-0/+5

2018-06-05tests: Specify the death test style to avoid flakiness.Tao Bao2-0/+5
As warned below (while running the test), the default death test style (i.e. "fast") doesn't work well in a threaded context, which causes test flakiness (timeout or early exit). [WARNING] external/googletest/googletest/src/gtest-death-test.cc:836:: Death tests use fork(), which is unsafe particularly in a threaded context. For this test, Google Test detected 3 threads. This CL specifies the death test styles to be "threadsafe" for the following death tests. - RangeSetTest.GetBlockNumber - RangeSetTest.file_range - ScreenRecoveryUITest.LoadAnimation_MissingAnimation Test: mmma -j bootable/recovery Test: Run recovery_unit_test on marlin. Test passes and the above warning is gone. Change-Id: I245bbc09286702d5cb326f878c4391e842b66cc5
2018-05-26updater: Add Commmand class to manage BBOTA commands.Tao Bao1-0/+37
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

2018-05-09screen_ui: Fix an issue in RTL locale detection.Tao Bao1-1/+1
The CL in [1] moved android.os.RecoverySystem to send the locale argument in well-formed BCP 47 language tags (e.g. "en-US" instead of "en_US"), with the matching changes to recovery code in [2]. However, the one in ScreenRecoveryUI::SetLocale() was missed, which broke RTL locale detection when using new format. [1] commit 38715228 in platform/frameworks/base [2] commit 2078b22e in platform/bootable/recovery Test: Set the locale to "ar-EG". `Run graphics test` under recovery. Check the progress bar. Test: Run recovery_unit_test on marlin. Change-Id: I7c7f5e0725bfb096109c7192c19f3f008e8e47e3
2018-05-09tests: Add tests for ScreenRecoveryUI.Tao Bao1-0/+167
In order to support that, this CL adds Paths::set_resource_dir() to override the default resource dir ("/res/images/") that's only available under recovery. Note that since there're external modules depending on libminui, it adds a separate function of res_set_resource_dir(), instead of requiring the dependency on libotautil for everyone. Test: mmma -j bootable/recovery Test: Run recovery_unit_test on marlin. Change-Id: I0a7dcf4476808bea9e634eaffc9676f6cbaf92b7

2018-05-03screen_ui: Merge Menu::Start() into its ctor.Tao Bao1-21/+7
Since we instantiate a Menu object each time for a given set of header/items, we don't have a use case of re-populating an existing Menu with different data (which is what Menu::Start() does). Test: mmma -j bootable/recovery Test: Run recovery_unit_test on marlin. Test: Build and boot into recovery image on angler. Check the UI. Change-Id: Iaa2ba9d406ebd74c015e43198c17c5335b38df53

2017-11-09Load-balancing update_verifier worker threads.Tao Bao1-0/+80
Prior to this CL, the block verification works were assigned based on the pattern of the ranges, which could lead to unbalanced workloads. This CL adds RangeSet::Split() and moves update_verifier over. a) For the following care_map.txt on walleye: system 20,0,347,348,540,556,32770,33084,98306,98620,163842,164156,229378,229692,294914,295228,524289,524291,524292,524348,529059 vendor 8,0,120,135,32770,32831,94564,98304,98306 Measured the time costs prior to and with this CL with the following script. $ cat test_update_verifier.sh #!/bin/sh adb shell stop adb shell "cp /data/local/tmp/care_map.txt /data/ota_package/" for i in $(seq 1 50) do echo "Iteration: $i" adb shell "bootctl set-active-boot-slot 0" adb shell "echo 3 > /proc/sys/vm/drop_caches" adb shell "time /data/local/tmp/update_verifier" sleep 3 done Without this CL, the average time cost is 5.66s, while with the CL it's reduced to 3.2s. b) For the following care_map.txt, measured the performance on marlin: system 18,0,271,286,457,8350,32770,33022,98306,98558,163842,164094,196609,204800,229378,229630,294914,295166,501547 vendor 10,0,42,44,85,2408,32770,32806,32807,36902,74242 It takes 12.9s and 5.6s without and with the CL respectively.

2017-11-07otautil: Remove the aborts in RangeSet::Parse().Tao Bao1-14/+64
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
2017-10-11Move rangeset.h and print_sha1.h into otautil.Tao Bao1-2/+2
Also drop the "bootable/recovery" path in LOCAL_C_INCLUDES from applypatch modules. Test: lunch aosp_{angler,bullhead,fugu,dragon,sailfish}-userdebug; mmma bootable/recovery Change-Id: Idd602a796894f971ee4f8fa3eafe36c42d9de986
2017-08-19Move Image/ImageChunk/PatchChunk declaration into header filesTianjie Xu1-1/+1
1. Move the declaration of the Image classes to the header file to make testing easier. 2. Also move rangeset.h to bootable/recovery to allow access in imgdiff. Test: recovery component test Change-Id: I68a863e60a3f2e7ae46ee48f48eb15391f5f4330
2017-08-01Add implemention of SortedRangeSetTianjie Xu1-0/+47
This is useful in imgdiff to maintain the block ranges of splitted source image. Bug: 34220646 Test: mma && unit tests pass Change-Id: I6427f2ea50f0e3b0aa3dd01880ec0206679b7429
2017-07-27otautil: Clean up dirCreateHierarchy().Tao Bao1-21/+11
- Changed to std::string based implementation (mostly moved from the former make_parents() in updater/install.cpp); - Removed the timestamp parameter, which is only neeed by file-based OTA; - Changed the type of mode from int to mode_t; - Renamed dirCreateHierarchy() to mkdir_recursively(). Test: recovery_unit_test passes. Test: No external user of dirCreateHierarchy() in code search. Change-Id: I71f8c4b29bab625513bbc3af6d0d1ecdc3a2719a
2017-07-25otautil: Delete dirUnlinkHierarchy().Tao Bao1-32/+0
This function has become obsolete since we've removed file-based OTA support (it was needed by 'delete_recursive' edify function earlier). Test: mmma -j bootable/recovery Test: Code search shows no active user of the function. Change-Id: If6faaa759d4c849b79acba4e6adb82baadc89f7a

2017-04-03Change the internal representation in RangeSet.Tao Bao1-6/+34
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'). Test: recovery_unit_test Test: Apply an incremental update with the new updater. Change-Id: Ia1fbb343370a152e1f7aa050cf914c2da09b1396
2017-03-31Move parse_range() and range_overlaps() into RangeSet.Tao Bao1-0/+84
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

matches_locale was expecting input locale string to have at most one underscore; as a result "zh_CN_#Hans" ignores "zh_CN" and matches into "zh". Fix the match function and add unit tests. Bug: 27837319 Change-Id: I4e8a66f91cae6ac2a46b6bf21f670d5ea564c7c8
2016-03-31recovery: use __android_log_pmsg_file_write for log filesMark Salyzyn1-0/+92
(cherry-pick from commit a4f701af93a5a739f34823cde0c493dfbc63537a) - Add call to __android_log_pmsg_file_write for recovery logging. - Add call to refresh pmsg if we reboot back into recovery and then allow overwrite of those logs. - Add a new one-time executable recovery-refresh that refreshes pmsg in post-fs phase of init. We rely on pmsg eventually scrolling off to age the content after recovery-persist has done its job. - Add a new one-time executable recovery-persist that transfers from pmsg to /data/misc/recovery/ directory if /cache is not mounted in post-fs-data phase of init. - Build and appropriately trigger the above two as required if BOARD_CACHEIMAGE_PARTITION_SIZE is undefined. - Add some simple unit tests NB: Test failure is expected on systems that do not deliver either the recovery-persist or recovery-refresh executables, e.g. systems with /cache. Tests also require a timely reboot sequence of test to truly verify, tests provide guidance on stderr to direct. Bug: 27176738 Change-Id: I17bb95980234984f6b2087fd5941b0a3126b706b
