- Add man page sections '(N)' to external references, and '()' on
functions described in the same man page.
- Escape minus signs when those are expected to be used on the command
line or files.
- Mark files and variables in italic; Note headings, function names,
constants, program options and man page references in bold.
- Do not justify and hyphenate SEE ALSO section, and avoid hyphenation
on symbol names by prepending them with \%.
- Remove trailing dot from NAME section description.
- Split sections with a no-op command '.', to visually distinguish them
but to avoid introducing spurious vertical space in the formatted
output.
- Add explicit .sp commands in the SYNOPSIS section between function
prototypes, and fix space placement in function protoypes.
- Split header includes with .br (instead of the explicit or implicit
.sp) so that they are vertically contiguous.
- Add missing {} around SELINUXTYPE and POLICYTYPE variable text in
paths.
- Remove unneeded formatting commands.
- Remove spurious blank lines.

.SH "NAME"
|
|
user_contexts \- The SELinux user contexts configuration files
|
|
.
|
|
.SH "DESCRIPTION"
|
|
These optional user context configuration files contain entries that allow SELinux-aware login applications such as
|
|
.BR PAM (8)
|
|
(running in their own process context), to determine the context that a users login session should run under.
|
|
.sp
|
|
SELinux-aware login applications generally use one or more of the following libselinux functions that read these files from the active policy path:
|
|
.RS
|
|
.BR get_default_context (3)
|
|
.br
|
|
.BR get_ordered_context_list (3)
|
|
.br
|
|
.BR get_ordered_context_list_with_level (3)

.BR get_default_context_with_rolelevel (3)

.sp
|
|
There can be one file for each SELinux user configured on the system. The file path is formed using the path returned by
|
|
.BR \%selinux_user_contexts_path (3)
|
|
for the active policy, with the SELinux user name appended, for example:
|
|
.RS
|
|
.I /etc/selinux/{SELINUXTYPE}/contexts/users/unconfined_u
|
|
.br
|
|
.I /etc/selinux/{SELINUXTYPE}/contexts/users/xguest_u
|
|
.RE
|
|
.sp
|
|
Where \fI{SELINUXTYPE}\fR is the entry from the selinux configuration file \fIconfig\fR (see \fBselinux_config\fR(5)).
|
|
.sp
|
|
These files contain context information as described in the
|
|
.B FILE FORMAT
|
|
section.
|
|
.
|
|
.SH "FILE FORMAT"
|
|
Each line in the user context configuration file consists of the following:
|
|
.RS
|
|
.I login_process user_login_process
|
|
.RE
|
|
.sp
|
|
Where:
|
|
.RS
|
|
.I login_process
|
|
.RS
|
|
This consists of a \fIrole\fB:\fItype\fR[\fB:\fIrange\fR] entry that represents the login process context.
|
|
.RE
|
|
.I user_login_process
|
|
.RS
|
|
This consists of a \fIrole\fB:\fItype\fR[\fB:\fIrange\fR] entry that represents the user login process context.
