If that problem has been fixed, this would imply that SKAS should work on x86-64... or not? Well, I remember that problem being on IA32 emulation and IA32 wasn't included in the patch (for what I can see). Can you ask more information about this? Also, could you verify if at least with noprocmm and a host SKAS-V9 it works? Two things are to check: * Uml64 should use /proc/mm64 (unimplemented) * Uml64 should use the right version of PTRACE_FAULTINFO (I don't remember what I did, if I introduced PTRACE_EX_FAULTINFO or if I directly added the missing trap_no field in PTRACE_FAULTINFO; please verify). I won't have the time to check this at least until the 22 June.
