* applypatch: Add backup_source parameter to PatchPartition.Tao Bao2019-09-233-11/+14
| | | | | | | | | | | | | | | | | | | And set it to false when installing recovery image via applypatch. We only need to back up the source partition when doing in-place update (e.g. when updating a given partition under recovery). When installing recovery image via applypatch, we won't touch the source partition (i.e. /boot). Removing the backup step also allows dropping the dac_override_allowed permission. Previously it was needed due to the access to /cache. Because applypatch runs as root:root, while /cache is owned by system:cache with 0770. Bug: 68319577 Test: Invoke the code that installs recovery image; check that recovery is installed successfully without denials. Test: recovery_unit_test passes on taimen.

* applypatch: Use static libs for libbrotli and libbz.Tao Bao2019-09-231-2/+4
| | | | | | | | | | | | | | | | | | | | Prior to this CL, applypatch was the only user of libbrotli.so and libbz.so (update_engine and puffin have been using the static versions). This CL switches applypatch to their static versions to save space in /system.

* applypatch: Refactor applypatch().Tao Bao2018-08-314-347/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | applypatch() was initially designed for file-based OTA, operating on individual files. It was later extended to allow patching eMMC targets as a whole, in favor of block-based updates. As we have deprecated file-based OTA since Oreo, part of the code in applypatch() has become obsolete. This CL refactors the related functions, by removing the obsolete logic and focusing on eMMC targets. Since this CL substantially changes applypatch APIs, it adds new functions to avoid unintentionally mixing them together. In particular, it removes `applypatch()`, `applypatch_check()`, `applypatch_flash()`, and adds `PatchPartition()`, `PatchPartitionCheck()`, `FlashPartition()` and `CheckPartition()`. It also replaces the old Edify functions `apply_patch()` and `apply_patch_check()` with `patch_partition()` and `patch_partition_check()` respectively. This CL requires matching changes to OTA generation script (in the same topic). Bug: 110106408 Test: Run recovery_unit_test and recovery_component_test on marlin. Test: `m dist` with non-A/B target. Verify /system/bin/install-recovery.sh on device. Test: `m dist` with non-A/B target using BOARD_USES_FULL_RECOVERY_IMAGE. Verify /system/bin/install-recovery.sh on device.

* applypatch: Change applypatch command-line arguments.Tao Bao2018-07-205-147/+145
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This applies to the standalone applypatch executable (/system/bin/applypatch on device). This executable is only used when installing (via patching or flashing) a recovery image on non-A/B device. This CL removes the support for patching non-eMMC targets from applypatch that has been deprecated as part of file-based OTA. For patching eMMC targets, it also drops the support for accepting multiple patches (not useful, since the source file must be fixed). This CL needs the matching change in the same topic, which writes the script of "/system/bin/install-recovery.sh". Note that this CL doesn't chanage the applypatch API signatures, in order to minimize the CL size. *BEFORE* usage: /system/bin/applypatch [-b <bonus-file>] <src-file> <tgt-file> <tgt-sha1> <tgt-size> [<src-sha1>:<patch> ...] or /system/bin/applypatch -c <file> [<sha1> ...] or /system/bin/applypatch -l Filenames may be of the form EMMC:<partition>:<len_1>:<sha1_1>:<len_2>:<sha1_2>:... to specify reading from or writing to an EMMC partition. *AFTER* Usage: check mode applypatch --check EMMC:<target-file>:<target-size>:<target-sha1> flash mode applypatch --flash <source-file> --target EMMC:<target-file>:<target-size>:<target-sha1> patch mode applypatch [--bonus <bonus-file>] --patch <patch-file> --target EMMC:<target-file>:<target-size>:<target-sha1> --source EMMC:<source-file>:<source-size>:<source-sha1> show license applypatch --license Bug: 110106408 Test: Run recovery_component_test and recovery_unit_test on marlin.

* applypatch: Consolidate CacheSizeCheck() and MakeFreeSpaceOnCache().Tao Bao2018-07-133-21/+12
| | | | | | | | | | | | | | | | | | 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.

* applypatch: Fix the return type of FreeSpaceForFile().Tao Bao2018-07-123-19/+33
| | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Convert deflate image chunks to raw if the raw data is smallerTianjie Xu2018-05-243-3/+5
| | | | | | | | | | | | | | | | | The imgpatch will fail on empty deflates because the bspatch won't call the sink function if the target length is zero. Instead of compressing an empty string, it's cleaner to not generate such empty deflate chunks in the patch. Therefore, we can just convert the chunk type to raw if the target length is smaller than the patch data. Also adjust some unit tests and add the testdata gzipped_source & gzipped_target. These two files are ~1K each and are generated by gzipping two slightly different regular files.

| | | | | | | | | | | Add a mandatory option in imgdiff to write the split info (i.e. patch_size, tgt_size, src_ranges) to file when handling large apks.

* Improve imgdiff for large zip filesTianjie Xu2017-09-062-19/+480
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the cache size limit for OTA generation, we used to split large zip files linearly into pieces and do bsdiff on them. As a result, i) we lose the advantage of imgdiff; ii) if there's an accidental order change of some huge files inside the zip, we'll create an insanely large patch. This patch splits the src&tgt more smartly based on the zip entry_name. If the entry_name is empty or no matching source is found for a target chunk, we'll skip adding its source and later do a bsdiff against the whole split source image (this rarely happens in our use cases except for the metadata inside a ziparchive). After the split, the target pieces are continuous and block aligned, while the sources pieces are mutually exclusive. (Some of the source blocks may not be used if there's no matching entry_name in the target.) Then we will generate patches accordingly between each split image pairs. Afterwards, if we apply imgpatch to each pair of split source/target images and add up the patched result, we can get back the original target image. For example: Input: [src_image, tgt_image] Split: [src-0,tgt-0; src-1,tgt-1, src-2,tgt-2] Diff: [ patch-0; patch-1; patch-2] Patch: [(src-0,patch-0)=tgt-0; (src-1,patch-1)=tgt-1; (src-2,patch-2)=tgt-2;] Append: [tgt-0 + tgt-1 + tgt-2 = tgt_image] Peformance: For the small package in b/34220646, we decrease the patch size of chrome.apk dramatically from 30M to 400K due to the order change of two big .so files. On two versions of angler, I also observe decent patch size decrease. For chrome.apk, we reduced the size from 5.9M to 3.2M; and for vevlet.apk from 8.0M to 6.5M.

* Fix a rare failure for imgdiff when random data equals gzip headerTianjie Xu2017-07-071-11/+14
| | | | | | | | | | | In a rare case, a random chunk will pass both the gzip header check and the inflation process; but fail the uncompressed length check in the footer. This leads to a imgdiff failure. So, we should treat this chunk as 'normal' instead of 'inflated' while generating the patch.

| | | | | | | | | | | | | | | | | 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.

* | Remove ota_close(int) and ota_fclose(FILE*).Tao Bao2016-11-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | We should always use unique_fd or unique_file to hold the FD or FILE* pointer when opening via ota_(f)open functions. This CL avoids accidentally closing raw FDs or FILE* pointers that are managed by unique_fd/unique_file. Test: recovery_component_test passes. Change-Id: If58eb8b5c5da507563f85efd5d56276472a1c957
* | Add ota_close(unique_fd&) and ota_fclose(std::unique_ptr<FILE>&).Tao Bao2016-11-231-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were using the below sequence prior to the CL in [1]. unique_fd fd(ota_open(...)); ota_close(fd); fd.reset(ota_open(...)); fd.reset() may unintentionally close the newly opened FD if it has the same value as the early ota_open. The CL in [1] changed to "ota_close(fd.release())" to avoid the issue. This CL adds a new overloaded function ota_close(unique_fd&) to handle the release automatically. Similarly add ota_fclose(std::unique_ptr<FILE>&). [1] commit 48cf770471ef53fbf0a1837196220862a0bdb18d. Bug: 33034669 Test: recovery_component_test passes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nexus 4 has flash errors that manifest during large writes (eg, of the radio partition). Writes of some blocks seem to be dropped silently, without any errors being returned to the user level. Make two changes to the partition-writing code: - break it up into 1MB writes instead of writing partitions with a single fwrite() call. Pause for 50ms in between every chunk. - read the partition back after writing and verify that we read what we wrote. Drop caches before reading so we (hopefully) are reading off the actual flash and not some cache. Neither of these should be necessary.

Move all the parsing of arguments into main.c (for the standalone binary) and into install.c (for the updater function). applypatch() takes patches as Value objects, so we can pass in blobs extracted from the package without ever writing them to temp files. The patching code is changed to read the patch from memory instead of a file. A bunch of compiler warnings (mostly about signed vs unsigned types) are fixed. Support for the IMGDIFF1 format is dropped. (We've been generating IMGDIFF2 packages for some time now.) Change-Id: I217563c500012750f27110db821928a06211323f
* relocate applypatch; add type system and new functions to edifyDoug Zongker2010-02-1817-0/+3882
- Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
