6 smbmount_selinux - Security Enhanced Linux Policy for the smbmount pro‐
7 cesses
8
10 Security-Enhanced Linux secures the smbmount processes via flexible
11 mandatory access control.
12 The smbmount processes execute with the smbmount_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 For example:
18 ps -eZ | grep smbmount_t
20
24 The smbmount_t SELinux type can be entered via the smbmount_exec_t file
25 type.
26 The default entrypoint paths for the smbmount_t domain are the follow‐
28 ing:
29 /usr/bin/smbmnt, /usr/bin/smbmount
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 smbmount policy is very flexible allowing users to setup their smbmount
40 processes in as secure a method as possible.
41 The following process types are defined for smbmount:
43 smbmount_t
45 Note: semanage permissive -a smbmount_t can be used to make the process
47 type smbmount_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. smb‐
54 mount policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run smbmount with the tightest access
56 possible.
57 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‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Disabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91 setsebool -P nscd_use_shm 1

97 The SELinux process type smbmount_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

149 SELinux requires files to have an extended attribute to define the file
150 type.
151 You can see the context of a file using the -Z option to ls
153 Policy governs the access confined processes have to these files.
155 SELinux smbmount policy is very flexible allowing users to setup their
156 smbmount processes in as secure a method as possible.
157 The following file types are defined for smbmount:
159 smbmount_exec_t
163 - Set files with the smbmount_exec_t type, if you want to transition an
165 executable to the smbmount_t domain.
166 Paths:
169 /usr/bin/smbmnt, /usr/bin/smbmount
170 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.
