2016-01-07updater: Add a function to check first blockTianjie Xu1-0/+55
Add and register a function to check if the device has been remounted since last update during incremental OTA. This function reads block 0 and executes before partition recovery for version >= 4. Bug: 21124327 Change-Id: I8b915b9f1d4736b3609daa9d16bd123225be357f (cherry picked from commit 30bf4765593e639966df9f460df22c3fe912e7bf)

2015-10-19Error correction: Use libfec in blockimg.cpp for recoverySami Tolvanen1-0/+76
Add block_image_recover function to rewrite corrupted blocks on the partition. This can be attempted if block_image_verify fails. Note that we cannot use libfec during block_image_update as it may overwrite blocks required for error correction. A separate recovery pass in case the image is corrupted is the only viable option.

2015-09-26updater: Skip empty lines in the transfer list file.Tao Bao1-0/+4
We have the last line being empty as a result of android::base::Split("a\nb\n"), which leads to "missing command" warnings in the update. Just skip all the empty lines. Bug: 24373789 Change-Id: I5827e4600bd5cf0418d95477e4592fec47bbd3a9

2015-05-29Handle BLKDISCARD failuresSami Tolvanen1-2/+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. Bug: 20614277 Change-Id: I33867ba9337c514de8ffae59f28584b285324067 (cherry picked from commit cc2428c8181d18c9a88db908fa4eabd2db5601ad)

2015-04-17Don't remove existing explicitly stashed blocksSami Tolvanen1-10/+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

2015-01-30Support resuming block based OTAsSami Tolvanen1-346/+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.

2014-09-26support for version 2 of block image diffsDoug Zongker1-45/+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.
