[Xen-devel] [PATCH] fix out-of-bounds memory access in linux-xen-low.c (gdbserver)

[Simon Kagstrom <simon.kagstrom@xxxxxx>]

The following patch fixes an out-of-bounds memory access in
xc_ptrace.c. Currently, Xen always copies the entire 512 byte extended
FPU state (fxsave) even if only the "regular" FPU state was
requested.

This breaks since the memory buffer allocated in
linux-xen-low.c:regsets_fetch_inferior_registers() is only large
enough to hold the "plain" FPU registers.
