NAME

6       user_screen_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       user_screen processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the user_screen processes via  flexible
11       mandatory access control.
12
13       The  user_screen processes execute with the user_screen_t SELinux type.
14       You can check if you have these processes running by executing  the  ps
15       command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep user_screen_t

ENTRYPOINTS

24       The  user_screen_t  SELinux  type  can be entered via the screen_exec_t
25       file type.
26
27       The default entrypoint paths for the user_screen_t domain are the  fol‐
28       lowing:
29
30       /usr/bin/tmux, /usr/bin/screen
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       user_screen  policy  is  very  flexible  allowing  users to setup their
40       user_screen processes in as secure a method as possible.
41
42       The following process types are defined for user_screen:
43
44       user_screen_t
45
46       Note: semanage permissive -a user_screen_t can  be  used  to  make  the
47       process  type user_screen_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       user_screen policy is extremely flexible and has several booleans  that
55       allow  you to manipulate the policy and run user_screen with the tight‐
56       est access possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to  support  NFS  home directories, you must turn on the
68       use_nfs_home_dirs boolean. Enabled by default.
69
70       setsebool -P use_nfs_home_dirs 1
71
72
73
74       If you want to support SAMBA home directories, you  must  turn  on  the
75       use_samba_home_dirs boolean. Disabled by default.
76
77       setsebool -P use_samba_home_dirs 1

MANAGED FILES

82       The  SELinux  process  type user_screen_t can manage files labeled with
83       the following file types.  The paths listed are the default  paths  for
84       these  file  types.  Note the processes UID still need to have DAC per‐
85       missions.
86
87       faillog_t
88
89            /var/log/btmp.*
90            /var/log/faillog.*
91            /var/log/tallylog.*
92            /var/run/faillock(/.*)?
93
94       initrc_var_run_t
95
96            /var/run/utmp
97            /var/run/random-seed
98            /var/run/runlevel.dir
99            /var/run/setmixer_flag

COMMANDS

103       semanage fcontext can also be used to manipulate default  file  context
104       mappings.
105
106       semanage  permissive  can  also  be used to manipulate whether or not a
107       process type is permissive.
108
109       semanage module can also be used to enable/disable/install/remove  pol‐
110       icy modules.
111
112       semanage boolean can also be used to manipulate the booleans
113
114
115       system-config-selinux is a GUI tool available to customize SELinux pol‐
116       icy settings.
