NAME

6       user_seunshare_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       user_seunshare processes
8

DESCRIPTION

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

22

ENTRYPOINTS

24       The  user_seunshare_t  SELinux  type  can  be  entered  via  the  seun‐
25       share_exec_t file type.
26
27       The default entrypoint paths for the user_seunshare_t  domain  are  the
28       following:
29
30       /usr/sbin/seunshare
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_seunshare  policy  is  very flexible allowing users to setup their
40       user_seunshare processes in as secure a method as possible.
41
42       The following process types are defined for user_seunshare:
43
44       user_seunshare_t
45
46       Note: semanage permissive -a user_seunshare_t can be used to  make  the
47       process  type user_seunshare_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       user_seunshare policy is extremely flexible and  has  several  booleans
55       that allow you to manipulate the policy and run user_seunshare with the
56       tightest access possible.

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‐

MANAGED FILES

164       The SELinux process type user_seunshare_t can manage files labeled with
165       the following file types.  The paths listed are the default  paths  for
166       these  file  types.  Note the processes UID still need to have DAC per‐
167       missions.
168
169       cgroup_t
170
171            /sys/fs/cgroup
172
173       sandbox_file_t
174
175
176       sandbox_tmpfs_type
177
178            all sandbox content in tmpfs file systems

COMMANDS

182       semanage fcontext can also be used to manipulate default  file  context
183       mappings.
184
185       semanage  permissive  can  also  be used to manipulate whether or not a
186       process type is permissive.
187
188       semanage module can also be used to enable/disable/install/remove  pol‐
189       icy modules.
190
191       semanage boolean can also be used to manipulate the booleans
192
