+Date:		May 2008

+Description:
+		The Trusted Computing Group(TCG) runtime Integrity
+		Measurement Architecture(IMA) maintains a list of hash
+		values of executables and other sensitive system files
+		loaded into the run-time of this system.  At runtime,
+		the policy can be constrained based on LSM specific data.
+		Policies are loaded into the securityfs file ima/policy
+		by opening the file, writing the rules one at a time and
+		then closing the file.  The new policy takes effect after
+		the file ima/policy is closed.
+
+		rule format: action [condition ...]
+
+		action: measure | dont_measure
+		condition:= base | lsm
+			base:	[[func=] [mask=] [fsmagic=] [uid=]]
+			lsm:	[[subj_user=] [subj_role=] [subj_type=]
+				 [obj_user=] [obj_role=] [obj_type=]]
+
+		base: 	func:= [BPRM_CHECK][FILE_MMAP][INODE_PERMISSION]
+			mask:= [MAY_READ] [MAY_WRITE] [MAY_APPEND] [MAY_EXEC]
+			fsmagic:= hex value
+			uid:= decimal value
+		lsm:  	are LSM specific
+
+		default policy:
+			# PROC_SUPER_MAGIC
+			dont_measure fsmagic=0x9fa0
+			# SYSFS_MAGIC
+			dont_measure fsmagic=0x62656572
+			# DEBUGFS_MAGIC
+			dont_measure fsmagic=0x64626720
+			# TMPFS_MAGIC
+			dont_measure fsmagic=0x01021994
+			# SECURITYFS_MAGIC
+			dont_measure fsmagic=0x73636673
+
+			measure func=BPRM_CHECK
+			measure func=FILE_MMAP mask=MAY_EXEC
+			measure func=INODE_PERM mask=MAY_READ uid=0
+
+		The default policy measures all executables in bprm_check,
+		all files mmapped executable in file_mmap, and all files
+		open for read by root in inode_permission.
+
+		Examples of LSM specific definitions:
+
+		SELinux:
+			# SELINUX_MAGIC
+			dont_measure fsmagic=0xF97CFF8C
+
+			dont_measure obj_type=var_log_t
+			dont_measure obj_type=auditd_log_t
+			measure subj_user=system_u func=INODE_PERM mask=MAY_READ
+			measure subj_role=system_r func=INODE_PERM mask=MAY_READ
+
+		Smack:
+			measure subj_user=_ func=INODE_PERM mask=MAY_READ
