* libotautil exports libfstab header.Tao Bao2019-04-031-0/+4
| | | | | | | | | | | | otautil/roots.h includes <fstab/fstab.h>, but users of otautil/roots.h don't need to explicitly depend on libfstab unless they have a real need. Also remove the unneeded include of <fstab/fstab.h> from fsck_unshare_blocks.cpp. Test: mmma -j bootable/recovery Change-Id: Id3dc995a4769e631ab242843ee439bd94b2bf0bc
* Move install to separate modulexunchang2019-03-293-0/+355

| | | | | | | We will reuse them to implement the fuse provider from block maps. Test: unit tests pass, sideload an OTA Change-Id: Iaa409d19569c4ccc0bb24e12518044fcddb45c69
* Move the parse of last_install to recovery-persistTianjie Xu2018-09-133-0/+148
| | | | | | | | | | | | | | | The recovery-persist used to look for the related recovery logs in persist storage, and copy them under /data/misc/recovery during the normal boot process. As we also want to find out the sideload information from last_install, it makes more sense to move the parse & report of non-a/b metrics to recovery-persist. Thus we can avoid the race condition of the file system between the native code and RecoverySystem. Bug: 114278989 Test: unit test pass, check the event buffer for metrics report Change-Id: I32d7b2b831bc74a61a70af9a2f0b8a7e9b3e36ee
* Enable c++17 in recovery_defaults.Tao Bao2018-08-281-21/+17

* Remove otafaultTianjie Xu2018-08-281-0/+1
| | | | | | | | | | Now it's less beneficial to inject I/O faults since we don't see many of them. Remove the library that mocks I/O failures. And switch to android::base I/O when possible. Bug: 113032079 Test: unit tests pass Change-Id: I9f2a92b7ba80f4da6ff9e2abc27f2680138f942c
* `recovery` uses more shared libraries.Tao Bao2018-08-081-9/+8
| | | | | | | | | | Bug: 110380063 Test: `m -j installclean && mmma -j bootable/recovery` with aosp_taimen-userdebug Test: Build (`m -j bootimage`) and boot into recovery. Check that `adb sideload` and `Run graphics test` both work. Test: Run recovery_unit_test and recovery_component_test on marlin. Change-Id: Ie6ed0e7cafa352d5faff9d1b6ccef724a0415e65
* Add an updater function to compute hash treeTianjie Xu2018-08-061-0/+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
* Fix the arguments passed to getopt_long(3).Tao Bao2018-07-172-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Drop the dependency on AB_OTA_UPDATER flag.Tao Bao2018-06-192-1/+13
| | | | | | | | | | | | | | | | This shortens the gap between A/B and non-A/B builds, by replacing the dependency on build-time flag with runtime detection instead. It also allows building and testing both paths regardless of the target OTA type. The size increase to /sbin/recovery looks negligible (< 0.01%). - marlin: increased from 2084928 to 2085024; - angler: increased from 2084776 to 2084896. Test: Run recovery_component_test on angler and marlin. Test: Sideload an A/B OTA package on marlin. Test: Sideload a non-A/B OTA package on angler.

* tests: Add tests for ScreenRecoveryUI.Tao Bao2018-05-092-0/+12
| | | | | | | | | | | | 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
* Move reboot() from common.h into otautil/sysutil.h.Tao Bao2018-05-043-0/+15
| | | | | | | | | | | | This breaks the dependency on common.h (which belongs to recovery/librecovery) from librecovery_ui. reboot() is now owned by libotautil, which is expected to be a leaf node to be depended on. With the change, recovery and updater also share the same reboot() code now. Test: mmma -j bootable/recovery Change-Id: I1cc5d702cfe49302048db33d31c9c87ddc97ac71

* otautil: Only build the needed files for host build.Tao Bao2018-05-041-7/+10
| | | | | | | This avoids unnecessarily breaking mac build. Test: `mmma -j bootable/recovery` on Linux and macOS. Change-Id: I1dc00364c895866a4757c2a43beb3432ae1e4113
* Merge libmounts into libotautil.Tao Bao2018-04-283-0/+116
| | | | | | | | | Export its header (mounts.h) from there, and drop the dot dot dependency from libupdater / updater. Test: mmma bootable/recovery Test: recovery_component_test Change-Id: Ic26a6b9b78a34dbe1f178b138f3abaafffbec44c
* Rename CacheLocation to Paths.Tao Bao2018-04-264-88/+111
| | | | | | | | | | 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
* Remove the old log files if cache space is insufficient for OTATianjie Xu2018-04-132-1/+13
| | | | | | | | | | | We set the limit of the max stash size to 80% of cache size. But the cache space can still be insufficient for the update if the log files occupy a large chunk of /cache. So remove the old logs for now to make room for the update. Bug: 77528881 Test: unit tests pass Change-Id: Ia8bcb0ace11f8164ad9290bfb360e08e31d282cb
* Set the update locations to default in CacheLocation's constructorTianjie Xu2018-03-082-9/+5
| | | | | | | | | Otherwise the applypatch executable will fail to back up the source file to /cache when patching the recovery image. Bug: 74198354 Test: run applypatch from boot to recovery Change-Id: I6e5b9cd06d6ed0b26066b779a348437ecf984b92
* Add a singleton CacheLocation to replace the hard coded locationsTianjie Xu2018-02-283-0/+105
| | | | | | | | | | | | 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
* Load-balancing update_verifier worker threads.Tao Bao2017-11-092-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* otautil: Remove the aborts in RangeSet::Parse().Tao Bao2017-11-072-40/+87
| | | | | | | | | | | | | | | | | | | 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

This way it stops requiring relative path ".." in LOCAL_C_INCLUDES (uncrypt and edify). Soong doesn't accept non-local ".." in "local_include_dirs".

* otautil: Clean up dirCreateHierarchy().Tao Bao2017-07-272-143/+95
| | | | | | | | | | | | - 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().
