6 mount_ecryptfs_selinux - Security Enhanced Linux Policy for the
7 mount_ecryptfs processes
8
10 Security-Enhanced Linux secures the mount_ecryptfs processes via flexi‐
11 ble mandatory access control.
12
13 The mount_ecryptfs processes execute with the mount_ecryptfs_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 mount_ecryptfs_t
20
21
22
24 The mount_ecryptfs_t SELinux type can be entered via the
25 mount_ecryptfs_exec_t file type.
26
27 The default entrypoint paths for the mount_ecryptfs_t domain are the
28 following:
29
30 /usr/sbin/mount.ecryptfs, /usr/sbin/umount.ecryptfs,
31 /usr/sbin/mount.ecryptfs_private, /usr/sbin/umount.ecryptfs_private
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 mount_ecryptfs policy is very flexible allowing users to setup their
41 mount_ecryptfs processes in as secure a method as possible.
42
43 The following process types are defined for mount_ecryptfs:
44
45 mount_ecryptfs_t
46
47 Note: semanage permissive -a mount_ecryptfs_t can be used to make the
48 process type mount_ecryptfs_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
52
54 SELinux policy is customizable based on least access required.
55 mount_ecryptfs policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run mount_ecryptfs with the
57 tightest access possible.
58
59
60
61 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63
64 setsebool -P fips_mode 1
65
66
67
68 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70
71 setsebool -P nis_enabled 1
72
73
74
76 The SELinux process type mount_ecryptfs_t can manage files labeled with
77 the following file types. The paths listed are the default paths for
78 these file types. Note the processes UID still need to have DAC per‐
79 missions.

81 krb5_host_rcache_t

83 /var/tmp/krb5_0.rcache2
84 /var/cache/krb5rcache(/.*)?
85 /var/tmp/nfs_0
86 /var/tmp/DNS_25

104 SELinux requires files to have an extended attribute to define the file
105 type.
106
107 You can see the context of a file using the -Z option to ls
108
109 Policy governs the access confined processes have to these files.
110 SELinux mount_ecryptfs policy is very flexible allowing users to setup
111 their mount_ecryptfs processes in as secure a method as possible.
112
113 STANDARD FILE CONTEXT
114
115 SELinux defines the file context types for the mount_ecryptfs, if you
116 wanted to store files with these types in a diffent paths, you need to
117 execute the semanage command to specify alternate labeling and then use
118 restorecon to put the labels on disk.
119
120 semanage fcontext -a -t mount_ecryptfs_tmpfs_t '/srv/my‐
121 mount_ecryptfs_content(/.*)?'
122 restorecon -R -v /srv/mymount_ecryptfs_content
123
124 Note: SELinux often uses regular expressions to specify labels that
125 match multiple files.
126
127 The following file types are defined for mount_ecryptfs:
128
129
130
131 mount_ecryptfs_exec_t
132
133 - Set files with the mount_ecryptfs_exec_t type, if you want to transi‐
134 tion an executable to the mount_ecryptfs_t domain.
135
136
137 Paths:
138 /usr/sbin/mount.ecryptfs, /usr/sbin/umount.ecryptfs,
139 /usr/sbin/mount.ecryptfs_private, /usr/sbin/umount.ecryptfs_pri‐
140 vate
141
142
143 mount_ecryptfs_tmpfs_t
144
145 - Set files with the mount_ecryptfs_tmpfs_t type, if you want to store
146 mount ecryptfs files on a tmpfs file system.
147
148
149
150 Note: File context can be temporarily modified with the chcon command.
151 If you want to permanently change the file context you need to use the
152 semanage fcontext command. This will modify the SELinux labeling data‐
153 base. You will need to use restorecon to apply the labels.
154
155
157 semanage fcontext can also be used to manipulate default file context
158 mappings.
159
160 semanage permissive can also be used to manipulate whether or not a
161 process type is permissive.
162
163 semanage module can also be used to enable/disable/install/remove pol‐
164 icy modules.
165
166 semanage boolean can also be used to manipulate the booleans
167
168
169 system-config-selinux is a GUI tool available to customize SELinux pol‐
170 icy settings.
