6 samba_net_selinux - Security Enhanced Linux Policy for the samba_net
7 processes
8
10 Security-Enhanced Linux secures the samba_net processes via flexible
11 mandatory access control.
12
13 The samba_net processes execute with the samba_net_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 samba_net_t
20
21
22
24 The samba_net_t SELinux type can be entered via the samba_net_exec_t
25 file type.
26
27 The default entrypoint paths for the samba_net_t domain are the follow‐
28 ing:
29
30 /usr/bin/net
31
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 samba_net policy is very flexible allowing users to setup their
40 samba_net processes in as secure a method as possible.
41
42 The following process types are defined for samba_net:
43
44 samba_net_t
45
46 Note: semanage permissive -a samba_net_t can be used to make the
47 process type samba_net_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 samba_net policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run samba_net with the tightest
56 access possible.
57
58
59
60 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62
63 setsebool -P fips_mode 1
64
65
66
67 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69
70 setsebool -P nis_enabled 1
71
72
73
74 If you want to support NFS home directories, you must turn on the
75 use_nfs_home_dirs boolean. Disabled by default.
76
77 setsebool -P use_nfs_home_dirs 1
78
79
80
81 If you want to support SAMBA home directories, you must turn on the
82 use_samba_home_dirs boolean. Disabled by default.
83
84 setsebool -P use_samba_home_dirs 1
85
86
87
89 The SELinux process type samba_net_t can manage files labeled with the
90 following file types. The paths listed are the default paths for these
91 file types. Note the processes UID still need to have DAC permissions.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141
142 You can see the context of a file using the -Z option to ls
143
144 Policy governs the access confined processes have to these files.
145 SELinux samba_net policy is very flexible allowing users to setup their
146 samba_net processes in as secure a method as possible.
147
148 STANDARD FILE CONTEXT
149
150 SELinux defines the file context types for the samba_net, if you wanted
151 to store files with these types in a different paths, you need to exe‐
152 cute the semanage command to specify alternate labeling and then use
153 restorecon to put the labels on disk.
154
155 semanage fcontext -a -t samba_net_exec_t '/srv/samba_net/content(/.*)?'
156 restorecon -R -v /srv/mysamba_net_content
157
158 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160
161 The following file types are defined for samba_net:
162
163
164
165 samba_net_exec_t
166
167 - Set files with the samba_net_exec_t type, if you want to transition
168 an executable to the samba_net_t domain.
169
170
171
172 samba_net_tmp_t
173
174 - Set files with the samba_net_tmp_t type, if you want to store samba
175 net temporary files in the /tmp directories.
176
177
178
179 Note: File context can be temporarily modified with the chcon command.
180 If you want to permanently change the file context you need to use the
181 semanage fcontext command. This will modify the SELinux labeling data‐
182 base. You will need to use restorecon to apply the labels.
183
184
186 semanage fcontext can also be used to manipulate default file context
187 mappings.
188
189 semanage permissive can also be used to manipulate whether or not a
190 process type is permissive.
191
192 semanage module can also be used to enable/disable/install/remove pol‐
193 icy modules.
194
195 semanage boolean can also be used to manipulate the booleans
196
197
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
199 icy settings.
