CVS commit: src/lib/libnvmm



Module Name:    src
Committed By:   maxv
Date:           Sun Feb 17 20:25:46 UTC 2019

Modified Files:
        src/lib/libnvmm: libnvmm_x86.c

Log Message:
Fix handling of SIB instructions. We were jumping to the SIB node _before_
fetching the displacement, so the node would always think there was no
displacement.

This didn't alter the final GPA we would be touching - because it is
fetched from the kernel directly and not from the computation -, but it
altered the instruction length, and on some guests (like Fedora 64bit),
the VCPU would resume execution at the wrong RIP and crash.

Now these guests work.
