NAME

6       smbmount_selinux - Security Enhanced Linux Policy for the smbmount pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  smbmount  processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep smbmount_t
20
21
22

ENTRYPOINTS

24       The smbmount_t SELinux type can be entered via the smbmount_exec_t file
25       type.
26
27       The default entrypoint paths for the smbmount_t domain are the  follow‐
28       ing:
29
30       /usr/bin/smbmnt, /usr/bin/smbmount
31

PROCESS TYPES

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       smbmount policy is very flexible allowing users to setup their smbmount
40       processes in as secure a method as possible.
41
42       The following process types are defined for smbmount:
43
44       smbmount_t
45
46       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
51

BOOLEANS

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
58
59
60       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
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to deny any process from ptracing or  debugging  any  other
69       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
70       default.
71
72       setsebool -P deny_ptrace 1
73
74
75
76       If you want to allow any process  to  mmap  any  file  on  system  with
77       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
78       ean. Enabled by default.
79
80       setsebool -P domain_can_mmap_files 1
81
82
83
84       If you want to allow all domains write to kmsg_device, while kernel  is
85       executed  with  systemd.log_target=kmsg parameter, you must turn on the
86       domain_can_write_kmsg boolean. Disabled by default.
87
88       setsebool -P domain_can_write_kmsg 1
89
90
91
92       If you want to allow all domains to use other domains file descriptors,
93       you must turn on the domain_fd_use boolean. Enabled by default.
94
95       setsebool -P domain_fd_use 1
96
97
98
99       If  you  want to allow all domains to have the kernel load modules, you
100       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
101       default.
102
103       setsebool -P domain_kernel_load_modules 1
104
105
106
107       If you want to allow all domains to execute in fips_mode, you must turn
108       on the fips_mode boolean. Enabled by default.
109
110       setsebool -P fips_mode 1
111
112
113
114       If you want to enable reading of urandom for all domains, you must turn
115       on the global_ssp boolean. Disabled by default.
116
117       setsebool -P global_ssp 1
118

121       If  you  want  to allow confined applications to run with kerberos, you
122       must turn on the kerberos_enabled boolean. Enabled by default.
123
124       setsebool -P kerberos_enabled 1

MANAGED FILES

143       The SELinux process type smbmount_t can manage files labeled  with  the
144       following file types.  The paths listed are the default paths for these
145       file types.  Note the processes UID still need to have DAC permissions.
146

FILE CONTEXTS

196       SELinux requires files to have an extended attribute to define the file
197       type.
198
199       You can see the context of a file using the -Z option to ls
200
201       Policy  governs  the  access  confined  processes  have to these files.
202       SELinux smbmount policy is very flexible allowing users to setup  their
203       smbmount processes in as secure a method as possible.
204
205       The following file types are defined for smbmount:
206
207
208
209       smbmount_exec_t
210
211       - Set files with the smbmount_exec_t type, if you want to transition an
212       executable to the smbmount_t domain.
213
214
215       Paths:
216            /usr/bin/smbmnt, /usr/bin/smbmount
217
218
219       Note: File context can be temporarily modified with the chcon  command.
220       If  you want to permanently change the file context you need to use the
221       semanage fcontext command.  This will modify the SELinux labeling data‐
222       base.  You will need to use restorecon to apply the labels.
223
224

COMMANDS

226       semanage  fcontext  can also be used to manipulate default file context
227       mappings.
228
229       semanage permissive can also be used to manipulate  whether  or  not  a
230       process type is permissive.
231
232       semanage  module can also be used to enable/disable/install/remove pol‐
233       icy modules.
234
235       semanage boolean can also be used to manipulate the booleans
236
237
238       system-config-selinux is a GUI tool available to customize SELinux pol‐
239       icy settings.
