2019-05-01Implement FuseBlockDataProviderxunchang3-0/+64
Adds a fuse data provider that parses the metadata from a block map, reads the data from the given ranges of the block device; and provides the data to the fuse. Bug: 127071893 Test: unit tests pass, install a package from block map Change-Id: Ie9925ee9144e98642505b3f5e1a4a186d2b21ed0
2019-04-29Consolidate the codes that handle reboot/shutdown.Tao Bao2-10/+18
Test: Choose `Reboot system now`, `Power off`, `Reboot to bootloader` from recovery UI respectively. Test: `adb reboot recovery` while under sideload mode. Change-Id: I0f3d55b80b472178ea4f6970b29cd9df0778b639
2019-04-16Move load & restore logs to logging.cppxunchang2-10/+104
We perform these steps to perserve the recovery logs when wiping /cache partition. Move them to logging.cpp to keep the actually EraseVolume function concise. Bug: 130166585 Test: unit tests pass, mount cache and check last log after cache Change-Id: Idc52833817a446f3a0148a3dd2112f911c9ef48d
2019-04-15Move wipe cache|data to libinstallxunchang3-0/+297
Therefore, libinstall becomes the sole owner to handle the request from minadbd service. The change also includes 1. move logging.cpp out of librecovery 2. drop the dependency on common.h 3. now it's more sensible to move the wipe_cache as part of install_package. move the wipe_cache to the end of the function. Bug: 130166585 Test: wipe data and cache from menu Change-Id: I6f356dccdb38015c50acf756bac246f87c30fc1f
2019-04-03libotautil exports libfstab header.Tao Bao1-0/+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
2019-03-29Move install to separate modulexunchang3-0/+355
Build libinstall as a shared library. Also drop the dependency on the global variables in common.h. Test: unit tests pass, sideload an OTA Change-Id: I30a20047768ce00689fc0e7851c1c5d712a365a0
2019-03-26Move out the code to parse block map in MemMapxunchang2-71/+131
We will reuse them to implement the fuse provider from block maps. Test: unit tests pass, sideload an OTA Change-Id: Iaa409d19569c4ccc0bb24e12518044fcddb45c69
2018-09-13Move the parse of last_install to recovery-persistTianjie Xu3-0/+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

2018-08-28Remove otafaultTianjie Xu1-0/+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
2018-08-08`recovery` uses more shared libraries.Tao Bao1-9/+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
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

Test: compiles Bug: 78793464 Change-Id: Iff64bc1a597e70f749a9d825f7d386baa427be3d Merged-In: Iff64bc1a597e70f749a9d825f7d386baa427be3d (cherry picked from commit 92969c49dce519803ed0a1986781c474b1bbc82f)
2018-07-17Fix the arguments passed to getopt_long(3).Tao Bao2-0/+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. Change-Id: Ic6c37548f4db2f30aeabd40f387ca916eeca5392
2018-06-19Drop the dependency on AB_OTA_UPDATER flag.Tao Bao2-1/+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. Change-Id: I1d927d1ede9713fb42f73b4fe324aa5705ee6f99
2018-05-09tests: Add tests for ScreenRecoveryUI.Tao Bao2-0/+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
2018-05-04Move reboot() from common.h into otautil/sysutil.h.Tao Bao3-0/+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

2018-04-26Rename CacheLocation to Paths.Tao Bao4-88/+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
2018-04-13Remove the old log files if cache space is insufficient for OTATianjie Xu2-1/+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

2018-02-28Add a singleton CacheLocation to replace the hard coded locationsTianjie Xu3-0/+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
2017-11-09Load-balancing update_verifier worker threads.Tao Bao2-0/+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.

2017-11-07otautil: Remove the aborts in RangeSet::Parse().Tao Bao2-40/+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
2017-10-16otautil: Move RangeSet implementation into rangeset.cpp.Tao Bao3-151/+216

This reverts commit 26436d6d6010d5323349af7e119ff8f34f85c40c to re-land "Move error_code.h into otautil.". This way it stops requiring relative path ".." in LOCAL_C_INCLUDES (uncrypt and edify). Soong doesn't accept non-local ".." in "local_include_dirs". This CL needs to land with device-specific module changes (e.g. adding the dependency on libotautil).

2017-07-27otautil: Clean up dirCreateHierarchy().Tao Bao2-143/+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().
