NAME

6       showmount_selinux  -  Security  Enhanced Linux Policy for the showmount
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the showmount  processes  via  flexible
11       mandatory access control.
12
13       The  showmount processes execute with the showmount_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep showmount_t
20
21
22

ENTRYPOINTS

24       The  showmount_t  SELinux  type can be entered via the showmount_exec_t
25       file type.
26
27       The default entrypoint paths for the showmount_t domain are the follow‐
28       ing:
29
30       /usr/sbin/showmount
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       showmount  policy  is very flexible allowing users to setup their show‐
40       mount processes in as secure a method as possible.
41
42       The following process types are defined for showmount:
43
44       showmount_t
45
46       Note: semanage permissive -a  showmount_t  can  be  used  to  make  the
47       process  type  showmount_t  permissive. SELinux does not deny access to
48       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.  show‐
54       mount policy is extremely flexible and has several booleans that  allow
55       you to manipulate the policy and run showmount with the tightest access
56       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 allow confined applications to use nscd shared memory,
68       you must turn on the nscd_use_shm boolean. Enabled by default.
69
70       setsebool -P nscd_use_shm 1
71
72
73

FILE CONTEXTS

75       SELinux requires files to have an extended attribute to define the file
76       type.
77
78       You can see the context of a file using the -Z option to ls
79
80       Policy  governs  the  access  confined  processes  have to these files.
81       SELinux showmount policy is very flexible allowing users to setup their
82       showmount processes in as secure a method as possible.
83
84       STANDARD FILE CONTEXT
85
86       SELinux defines the file context types for the showmount, if you wanted
87       to store files with these types in a different paths, you need to  exe‐
88       cute  the  semanage  command to specify alternate labeling and then use
89       restorecon to put the labels on disk.
90
91       semanage fcontext -a -t showmount_exec_t '/srv/showmount/content(/.*)?'
92       restorecon -R -v /srv/myshowmount_content
93
94       Note: SELinux often uses regular expressions  to  specify  labels  that
95       match multiple files.
96
97       The following file types are defined for showmount:
98
99
100
101       showmount_exec_t
102
103       -  Set  files with the showmount_exec_t type, if you want to transition
104       an executable to the showmount_t domain.
105
106
107
108       Note: File context can be temporarily modified with the chcon  command.
109       If  you want to permanently change the file context you need to use the
110       semanage fcontext command.  This will modify the SELinux labeling data‐
111       base.  You will need to use restorecon to apply the labels.

113

COMMANDS

115       semanage  fcontext  can also be used to manipulate default file context
116       mappings.
117
118       semanage permissive can also be used to manipulate  whether  or  not  a
119       process type is permissive.
120
121       semanage  module can also be used to enable/disable/install/remove pol‐
122       icy modules.
123
124       semanage boolean can also be used to manipulate the booleans
125
126
127       system-config-selinux is a GUI tool available to customize SELinux pol‐
128       icy settings.
