Frankly I'm never a fan of syscall blocklisting. When I develop the Online Judge system for the programming contest training in Xidian University I deliberately avoid using seccomp. This thing is very likely to break innocent programs with some system change innocent as well (for example Glibc or libstdc++ update). -- Xi Ruoyao <xry111@xxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
