* Zero blocks before BLKDISCARDSami Tolvanen2015-06-091-9/+5
| | | | | | | | | | | Due to observed BLKDISCARD flakiness, overwrite blocks that we want to discard with zeros first to avoid later issues with dm-verity if BLKDISCARD is not successful. Bug: 20614277 Bug: 20881595 Change-Id: I0280fe115b020dcab35f49041fb55b7f8e793da3 (cherry picked from commit 96392b97f6bf1670d478494fb6df89a3410e53fa)

* Handle BLKDISCARD failuresSami Tolvanen2015-05-291-2/+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.

* Don't remove existing explicitly stashed blocksSami Tolvanen2015-04-171-10/+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

* Support resuming block based OTAsSami Tolvanen2015-01-301-346/+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.

* support for version 2 of block image diffsDoug Zongker2014-09-081-45/+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.
