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 users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Disabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Disabled by default.
91
92       setsebool -P nscd_use_shm 1
93
94
95
96       If you want to support NFS home  directories,  you  must  turn  on  the
97       use_nfs_home_dirs boolean. Enabled by default.
98
99       setsebool -P use_nfs_home_dirs 1
100
101
102
103       If  you  want  to  support SAMBA home directories, you must turn on the
104       use_samba_home_dirs boolean. Disabled by default.
105
106       setsebool -P use_samba_home_dirs 1

MANAGED FILES

111       The SELinux process type user_screen_t can manage  files  labeled  with
112       the  following  file types.  The paths listed are the default paths for
113       these file types.  Note the processes UID still need to have  DAC  per‐
114       missions.
115
116       faillog_t
117
118            /var/log/btmp.*
119            /var/log/faillog.*
120            /var/log/tallylog.*
121            /var/run/faillock(/.*)?
122
123       initrc_var_run_t
124
125            /var/run/utmp
126            /var/run/random-seed
127            /var/run/runlevel.dir
128            /var/run/setmixer_flag
129
130       user_tmp_type
131
132            all user tmp files
133
134

COMMANDS

136       semanage  fcontext  can also be used to manipulate default file context
137       mappings.
138
139       semanage permissive can also be used to manipulate  whether  or  not  a
140       process type is permissive.
141
142       semanage  module can also be used to enable/disable/install/remove pol‐
143       icy modules.
144
145       semanage boolean can also be used to manipulate the booleans
146
147
148       system-config-selinux is a GUI tool available to customize SELinux pol‐
149       icy settings.
