NAME

       sediffx - graphical SELinux policy difference tool

SYNOPSIS

       sediffx [-d] [ORIGINAL_POLICY ; MODIFIED_POLICY]

DESCRIPTION

       sediffx	allows	the  user to graphically inspect the semantic differences between two SELinux policies.  All supported policy elements are
       examined.

POLICY

       sediffx supports loading SELinux policies in one of four formats.

       source A single text file containing policy source for versions 12 through 21. This file is usually named policy.conf.

       binary A single file containing a monolithic kernel binary policy for versions 15 through 21. This file is usually named by version  -  for
	      example, policy.20.

       modular
	      A list of policy packages each containing a loadable policy module. The first module listed must be a base module.

       policy list
	      A single text file containing all the information needed to load a policy, usually exported by SETools graphical utilities.

       Policies do not need to be the same format. If not provided sediffx will begin with no policies loaded.

OPTIONS

       -d, --diff-now
	      Load the policies and differentiate them immediately.  This option requires the user to specify the policies on the command line.

       -h, --help
	      Print help information and exit.

       -V, --version
	      Print version information and exit.

DIFFERENCES

       sediffx categorizes differences in policy elements into one of three forms.

	      added  The element exists only in the modified policy.

	      removed
		     The element exists only in the original policy.

	      modified
		     The  element  exists  in both policies but its semantic meaning has changed.  For example, a class is modified if one or more
		     permissions are added or removed.

       For all rules with types as their source or target, two additional forms of difference are recognized.  This helps distinguish  differences
       due to new types from differences in rules for existing types.

	      added, new type
		     The  rule	exists only in the modified policy; furthermore, one or more of the types in the rule do not exist in the original
		     policy.

	      removed, missing type
		     The rule exists only in the original policy; furthermore, one or more of the types in the rule do not exist in  the  modified
		     policy.

NOTE

       Most shells interpret the semicolon as a metacharacter, thus requiring a backslash like so: sediffx original.policy ; modified.policy
