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 all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112 setsebool -P nscd_use_shm 1
114
118 The SELinux process type smbmount_t can manage files labeled with the
119 following file types. The paths listed are the default paths for these
120 file types. Note the processes UID still need to have DAC permissions.

202 SELinux requires files to have an extended attribute to define the file
203 type.
204 You can see the context of a file using the -Z option to ls
206 Policy governs the access confined processes have to these files.
208 SELinux smbmount policy is very flexible allowing users to setup their
209 smbmount processes in as secure a method as possible.
210 The following file types are defined for smbmount:
212 smbmount_exec_t
216 - Set files with the smbmount_exec_t type, if you want to transition an
218 executable to the smbmount_t domain.
219 Paths:
222 /usr/bin/smbmnt, /usr/bin/smbmount
223 Note: File context can be temporarily modified with the chcon command.
226 If you want to permanently change the file context you need to use the
227 semanage fcontext command. This will modify the SELinux labeling data‐
228 base. You will need to use restorecon to apply the labels.
229
232 semanage fcontext can also be used to manipulate default file context
233 mappings.
234 semanage permissive can also be used to manipulate whether or not a
236 process type is permissive.
237 semanage module can also be used to enable/disable/install/remove pol‐
239 icy modules.
240 semanage boolean can also be used to manipulate the booleans
242 system-config-selinux is a GUI tool available to customize SELinux pol‐
245 icy settings.
