6 showmount_selinux - Security Enhanced Linux Policy for the showmount
7 processes
8
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
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
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.
50
51
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
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 The following file types are defined for showmount:
85
86
87
88 showmount_exec_t
89
90 - Set files with the showmount_exec_t type, if you want to transition
91 an executable to the showmount_t domain.
92
93
94
95 Note: File context can be temporarily modified with the chcon command.
96 If you want to permanently change the file context you need to use the
97 semanage fcontext command. This will modify the SELinux labeling data‐
98 base. You will need to use restorecon to apply the labels.
99
100
102 semanage fcontext can also be used to manipulate default file context
103 mappings.
104
105 semanage permissive can also be used to manipulate whether or not a
106 process type is permissive.
107
108 semanage module can also be used to enable/disable/install/remove pol‐
109 icy modules.
110
111 semanage boolean can also be used to manipulate the booleans
112
113
114 system-config-selinux is a GUI tool available to customize SELinux pol‐
115 icy settings.
