* support for version 2 of block image diffsDoug Zongker2014-09-261-45/+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.

|/ | | | | | | | Otherwise, overflow problems can occur with images larger than 2G since the offsets will overflow a 32-bit off_t. Change-Id: I05951a38ebeae83ad2cb938594e8d8adb323e2aa Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
* fix two bugs in block image updaterDoug Zongker2014-08-211-18/+32
| | | | | | | | | The computation of file offsets was overflowing for partitions larger than 2 GB. The parsing of the transfer file could fail at the end if the data happened to not be properly null-terminated. Bug: 16984795 Change-Id: I3ce6eb3e54ab7b55aa9bbed252da5a7eacd3317a
