I have seen from some article,that if you set securebit to 1(could it be other value),that could increase system security(chattr),i can't figure this reason,i study the source code securebits.h file ,but still can't find out the meaning of SECURE_NOROOT and SECURE_NO_SETUID_FIXUP,and the issecure function,could someone point out what's the meaning of securebit?
