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 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 For example:
18 ps -eZ | grep mount_ecryptfs_t
20
24 The mount_ecryptfs_t SELinux type can be entered via the
25 mount_ecryptfs_exec_t file type.
26 The default entrypoint paths for the mount_ecryptfs_t domain are the
28 following:
29 /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 You can see the context of a process using the -Z option to ps
38 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 The following process types are defined for mount_ecryptfs:
44 mount_ecryptfs_t
46 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
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 If you want to allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64 setsebool -P authlogin_nsswitch_use_ldap 1
66 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71 setsebool -P fips_mode 1
73 If you want to allow confined applications to run with kerberos, you
77 must turn on the kerberos_enabled boolean. Enabled by default.
78 setsebool -P kerberos_enabled 1
80 If you want to allow system to run with NIS, you must turn on the
84 nis_enabled boolean. Disabled by default.
85 setsebool -P nis_enabled 1
87 If you want to allow confined applications to use nscd shared memory,
91 you must turn on the nscd_use_shm boolean. Enabled by default.
92 setsebool -P nscd_use_shm 1
94
98 The SELinux process type mount_ecryptfs_t can manage files labeled with
99 the following file types. The paths listed are the default paths for
100 these file types. Note the processes UID still need to have DAC per‐
101 missions.
102 mount_ecryptfs_tmpfs_t
104 pam_var_console_t
107 /var/run/console(/.*)?
109 user_tmp_t
111 /dev/shm/mono.*
113 /var/run/user(/.*)?
114 /tmp/.ICE-unix(/.*)?
115 /tmp/.X11-unix(/.*)?
116 /dev/shm/pulse-shm.*
117 /tmp/.X0-lock
118 /tmp/hsperfdata_root
119 /var/tmp/hsperfdata_root
120 /home/[^/]+/tmp
121 /home/[^/]+/.tmp
122 /tmp/gconfd-[^/]+
123
126 SELinux requires files to have an extended attribute to define the file
127 type.
128 You can see the context of a file using the -Z option to ls
130 Policy governs the access confined processes have to these files.
132 SELinux mount_ecryptfs policy is very flexible allowing users to setup
133 their mount_ecryptfs processes in as secure a method as possible.
134 STANDARD FILE CONTEXT
136 SELinux defines the file context types for the mount_ecryptfs, if you
138 wanted to store files with these types in a diffent paths, you need to
139 execute the semanage command to sepecify alternate labeling and then
140 use restorecon to put the labels on disk.
141 semanage fcontext -a -t mount_ecryptfs_tmpfs_t
143 '/srv/mymount_ecryptfs_content(/.*)?'
144 restorecon -R -v /srv/mymount_ecryptfs_content
145 Note: SELinux often uses regular expressions to specify labels that
147 match multiple files.
148 The following file types are defined for mount_ecryptfs:
150 mount_ecryptfs_exec_t
154 - Set files with the mount_ecryptfs_exec_t type, if you want to transi‐
156 tion an executable to the mount_ecryptfs_t domain.
157 Paths:
160 /usr/sbin/mount.ecryptfs, /usr/sbin/umount.ecryptfs,
161 /usr/sbin/mount.ecryptfs_private, /usr/sbin/umount.ecryptfs_pri‐
162 vate
163 mount_ecryptfs_tmpfs_t
166 - Set files with the mount_ecryptfs_tmpfs_t type, if you want to store
168 mount ecryptfs files on a tmpfs file system.
169 Note: File context can be temporarily modified with the chcon command.
173 If you want to permanently change the file context you need to use the
174 semanage fcontext command. This will modify the SELinux labeling data‐
175 base. You will need to use restorecon to apply the labels.
176
179 semanage fcontext can also be used to manipulate default file context
180 mappings.
181 semanage permissive can also be used to manipulate whether or not a
183 process type is permissive.
184 semanage module can also be used to enable/disable/install/remove pol‐
186 icy modules.
187 semanage boolean can also be used to manipulate the booleans
189 system-config-selinux is a GUI tool available to customize SELinux pol‐
192 icy settings.
