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
