selinux_raw_context_to_color - Return RGB color string for an SELinux
int selinux_raw_context_to_color(security_context_t raw,
selinux_raw_context_to_color returns a color_str associated to the raw
context raw provided that the mcstransd(8) daemon is running, the
policy is an MLS type policy (MCS or MLS) and there is a color
configuration file secolor.conf(5) (see the FILES section).
The color_str string is a space separated list of eight hexadecimal RGB
triples, each prefixed by a hash character (#). These represent the
user:role:type:range components of the foreground and background
colors. An example string is shown in the EXAMPLE section.
The returned color_str string must be freed with free(3).
If a color has not been configured for a specific user, role, type
and/or range component of context raw, then
selinux_raw_context_to_color will select the color returned in
color_str in order of precedence as follows:
role, type, range
user, type, range
user, role, range
user, role, type
If there are no entries in the secolor.conf file for any of the
components of context raw (or the file is not present), then the
default string returned in color_str is:
----- user ---- ---- role ---- ---- type ---- ---- range ----
#000000 #ffffff #000000 #ffffff #000000 #ffffff #000000 #ffffff
On success, zero is returned.
On failure, -1 is returned with errno set appropriately.
ENOENT If the mcstransd(8) daemon is not running.
selinux_raw_context_to_color obtains the translated entry from the
active policy secolor.conf(5) file as returned by
selinux_colors_path(3). The file format is described in
1. The primary use of selinux_raw_context_to_color is to return a color
that corresponds to a range, that can then be used to highlight
information at different MLS levels.
2. The mcstransd(8) daemon process security level must dominate the raw
security level passed to it by the selinux_raw_context_to_color
function. If not, the range color selected will be as defined by the
order of precedence.
selinux_raw_context_to_color returns the foreground and background
colors of the context string components (user:role:type:range) as RGB
triples as follows:
user : role : type : range
fg bg : fg bg : fg bg : fg bg
#000000 #ffffff #ffffff #000000 #d2b48c #ffa500 #000000 #008000
black white : white black : tan orange : black green
selinux(8), selinux_colors_path(3), mcstransd(8), secolor.conf(5),
