Add three new extended avrule statements with the following syntax: (allowx source_type target_type permissionx) (auditallowx source_type target_type permissionx) (dontauditx source_type target_type permissionx) source_type - type, typeattribute, or typealias target_type - type, typeattribute, typealias, or "self" keyword permissionx - named or anonymous permissionx statement, which has the syntax: (permissionx name (kind object expression)) name - unique identifier of the permissionx statement kind - must be "ioctl"; could be extended in the future object - class or classmap expression - standard CIL expression containing hexadecimal values, prefixed with '0x', and the expression keywords 'or', 'xor', 'and', 'not', 'range', or 'all'. Values must be between 0x0000 and 0xFFFF. Values may also be provided in decimal, or in octal if starting with '0'. For example: (allowx src_t tgt_t (ioctl cls (0x1111 0x1222 0x1333))) (allowx src_t tgt_t (ioctl cls (range 0x1400 0x14FF))) (allowx src_t tgt_t (ioctl cls (and (range 0x1600 0x19FF) (not (range 0x1750 0x175F))))) (permissionx ioctl_nodebug (ioctl cls (not (range 0x2010 0x2013)))) (allowx src_t tgt_t ioctl_nodebug) Signed-off-by: Steve Lawrence <slawrence@tresys.com> Acked-by: James Carter <jwcart2@tycho.nsa.gov> |
