Currently call gates are always treated as 32-bit gates. In IA-32e mode (either compatibility or 64-bit submode), system segment descriptors are always 64-bit. Treating them as 32-bit has the expected unfortunate effect: only the lower 32 bits of the offset are loaded, the stack pointer is truncated, a bad new stack pointer is loaded from the TSS (if switching privilege levels), etc. This change adds support for 64-bit call gate to the lcall and ljmp instructions. Additionally, there should be a check for non-canonical stack pointers, but I've omitted that since there doesn't seem to be checks for non-canonical addresses in this code elsewhere. I've left the raise_exception_err_ra lines unwapped at 80 columns to match the style in the rest of the file. Backports commit 0aca060526d3ff9632aaed66e8611814580c13de from qemu |
