Paul Moore 0faee34ebd policycoreutils: secon: add support for setrans color information in prompt output
This patch adds support for displaying SELinux context information in
colors defined by mcstrans(8)/secolor.conf(5).  The new behavior is
enabled through the use of the "-C/--color" option and requires the
"-P" option also be specified.

The reason for this addition is that in some situations, notably MLS,
users find it helpful to add SELinux context information to their prompt:

	# example taken from the RHEL6 CC certification bash scripts
	SEROLE=`secon -rP 2>/dev/null`
	SEMLS=`secon -lP 2>/dev/null`
	PS1="[\u/$SEROLE/$SEMLS@\h \W]\\$ "
	export PS1

With the added functionality provided by this patch we can also display
the associated color information (note the addition of the "C" option):

	SEROLE=`secon -rP 2>/dev/null`
	SEMLS=`secon -lPC 2>/dev/null`
	PS1="[\u/$SEROLE/$SEMLS@\h \W]\\$ "
	export PS1

Note that in the example above only the MLS range is colored, but the
patch does provide support for all of the color information provided
by mcstransd/secolor.conf (user,role,type,range).

Finally, one quick word on the colors themselves; the secolor.conf
configuration file allows 32-bit colors but the ANSI color coding only
allows 8-bit colors so the colors displayed by secon using the "-C"
option will be a bit lossy.

outputs data in a format suitable for a prompt
.TP
\fB\-C\fR, \fB\-\-color\fR
outputs data with the associated ANSI color codes (requires -P)
.TP

show the sensitivity level of the security context
.TP
\fB\-c\fR, \fB\-\-clearance\fR
show the clearance level of the security context
.TP
\fB\-m\fR, \fB\-\-mls-range\fR
show the sensitivity level and clearance, as a range, of the security context
.TP
\fB\-R\fR, \fB\-\-raw\fR
outputs the sensitivity level and clearance in an untranslated format.
.TP
\fB\-f\fR, \fB\-\-file\fR
gets the context from the specified file FILE
.TP
\fB\-L\fR, \fB\-\-link\fR
gets the context from the specified file FILE (doesn't follow symlinks)
.TP
\fB\-p\fR, \fB\-\-pid\fR
gets the context from the specified process PID
.TP
\fB\-\-pid\-exec\fR
gets the exec context from the specified process PID
.TP
\fB\-\-pid\-fs\fR
gets the fscreate context from the specified process PID
.TP
\fB\-\-current\fR, \fB\-\-self\fR
gets the context from the current process
.TP
\fB\-\-current\-exec\fR, \fB\-\-self\-exec\fR
gets the exec context from the current process
.TP
\fB\-\-current\-fs\fR, \fB\-\-self\-fs\fR
gets the fscreate context from the current process
.TP
\fB\-\-parent\fR
gets the context from the parent of the current process
.TP
\fB\-\-parent\-exec\fR
gets the exec context from the parent of the current process
.TP
\fB\-\-parent\-fs\fR
gets the fscreate context from the parent of the current process
.PP
Additional argument
.I CONTEXT
may be provided and will be used if no options have been specified to make
.B secon
get it's context from another source.
If that argument is
.I -
then the context will be read from stdin.
.br
If there is no arugment,
.B secon
will try reading a context from stdin, if that is not a tty, otherwise
.B secon
will act as though \fB\-\-self\fR had been passed.
.PP
If none of \fB\-\-user\fR, \fB\-\-role\fR, \fB\-\-type\fR, \fB\-\-level\fR or
\fB\-\-mls\-range\fR is passed.
Then all of them will be output.
