Performance between DBT and Scan-and-Patch

[Mu Li]

I just want to know how slow it will be if we only use scan-and-patch to run the loaded Linux binary.

hmm... int 0x80 will simply generate an exception, and for TLS-related instructions, simply replacing GS: prefix with a privileged one will do the trick too.

Actually,it would be way faster but would take lots of latency(exceptions are not for ee) when you make syscalls
