From a25b5d257dbfbff808b19bf8c48565435e6bef9d Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Mon, 8 Feb 2016 11:46:22 -0800 Subject: lzma: Port size-checking ulzman() version to coreboot We've had a second version of ulzma() that would check the input and output buffer sizes in libpayload for a while now. Since it's generally never a bad idea to double-check for overruns, let's port it to coreboot and use it where applicable. (This requires a small fix in the four byte at a time read optimization we only have in coreboot, since it made the stream counter hit the end a little earlier than the algorithm liked and could trigger an assertion.) BRANCH=None BUG=None TEST=Booted Oak, Jerry and Falco.
