NAME

6       samba_net_selinux  -  Security  Enhanced Linux Policy for the samba_net
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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

BOOLEANS

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. Enabled 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

MANAGED FILES

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.
92
93       auth_cache_t
94
95            /var/cache/coolkey(/.*)?
96
97       ctdbd_var_lib_t
98
99            /var/lib/ctdb(/.*)?
100            /var/lib/ctdbd(/.*)?
101
102       krb5_keytab_t
103
104            /var/kerberos/krb5(/.*)?
105            /etc/krb5.keytab
106            /etc/krb5kdc/kadm5.keytab
107            /var/kerberos/krb5kdc/kadm5.keytab
108
109       realmd_var_cache_t
110
111            /var/cache/realmd(/.*)?
112
113       samba_secrets_t
114
115            /etc/samba/smbpasswd
116            /etc/samba/passdb.tdb
117            /etc/samba/MACHINE.SID
118            /etc/samba/secrets.tdb

FILE CONTEXTS

122       SELinux requires files to have an extended attribute to define the file
123       type.
124
125       You can see the context of a file using the -Z option to ls
126
127       Policy  governs  the  access  confined  processes  have to these files.
128       SELinux samba_net policy is very flexible allowing users to setup their
129       samba_net processes in as secure a method as possible.
130
131       STANDARD FILE CONTEXT
132
133       SELinux defines the file context types for the samba_net, if you wanted
134       to store files with these types in a diffent paths, you need to execute
135       the  semanage  command  to  sepecify  alternate  labeling  and then use
136       restorecon to put the labels on disk.
137
138       semanage  fcontext   -a   -t   samba_net_tmp_t   '/srv/mysamba_net_con‐
139       tent(/.*)?'
140       restorecon -R -v /srv/mysamba_net_content
141
142       Note:  SELinux  often  uses  regular expressions to specify labels that
143       match multiple files.
144
145       The following file types are defined for samba_net:
146
147
148
149       samba_net_exec_t
150
151       - Set files with the samba_net_exec_t type, if you want  to  transition
152       an executable to the samba_net_t domain.
153
154
155
156       samba_net_tmp_t
157
158       -  Set  files with the samba_net_tmp_t type, if you want to store samba
159       net temporary files in the /tmp directories.
160
161
162
163       Note: File context can be temporarily modified with the chcon  command.
164       If  you want to permanently change the file context you need to use the
165       semanage fcontext command.  This will modify the SELinux labeling data‐
166       base.  You will need to use restorecon to apply the labels.
167
168

COMMANDS

170       semanage  fcontext  can also be used to manipulate default file context
171       mappings.
172
173       semanage permissive can also be used to manipulate  whether  or  not  a
174       process type is permissive.
175
176       semanage  module can also be used to enable/disable/install/remove pol‐
177       icy modules.
178
179       semanage boolean can also be used to manipulate the booleans
180
181
182       system-config-selinux is a GUI tool available to customize SELinux pol‐
183       icy settings.
