6 winbind_rpcd_selinux - Security Enhanced Linux Policy for the win‐
7 bind_rpcd processes
8
10 Security-Enhanced Linux secures the winbind_rpcd processes via flexible
11 mandatory access control.
12
13 The winbind_rpcd processes execute with the winbind_rpcd_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep winbind_rpcd_t
20
21
22
24 The winbind_rpcd_t SELinux type can be entered via the win‐
25 bind_rpcd_exec_t file type.
26
27 The default entrypoint paths for the winbind_rpcd_t domain are the fol‐
28 lowing:
29
30 /usr/libexec/samba/rpcd_lsad, /usr/libexec/samba/samba-dcerpcd
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 winbind_rpcd policy is very flexible allowing users to setup their win‐
40 bind_rpcd processes in as secure a method as possible.
41
42 The following process types are defined for winbind_rpcd:
43
44 winbind_rpcd_t
45
46 Note: semanage permissive -a winbind_rpcd_t can be used to make the
47 process type winbind_rpcd_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. win‐
54 bind_rpcd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run winbind_rpcd with the tight‐
56 est 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 confined applications to run with kerberos, you
68 must turn on the kerberos_enabled boolean. Enabled by default.
69
70 setsebool -P kerberos_enabled 1
71
72
73
74 If you want to allow samba and winbind-rpcd to share users home direc‐
75 tories, you must turn on the samba_enable_home_dirs boolean. Disabled
76 by default.
77
78 setsebool -P samba_enable_home_dirs 1
79
80
81
83 The SELinux process type winbind_rpcd_t can manage files labeled with
84 the following file types. The paths listed are the default paths for
85 these file types. Note the processes UID still need to have DAC per‐
86 missions.
87
88 samba_log_t
89
90 /var/log/samba(/.*)?
91
92 samba_var_t
93
94 /var/nmbd(/.*)?
95 /var/lib/samba(/.*)?
96 /var/cache/samba(/.*)?
97
98 user_home_type
99
100 all user home files
101
102 winbind_rpcd_var_run_t
103
104
105 winbind_var_run_t
106
107 /var/run/winbindd(/.*)?
108 /var/run/samba/winbindd(/.*)?
109 /var/lib/samba/winbindd_privileged(/.*)?
110 /var/cache/samba/winbindd_privileged(/.*)?
111
112
114 SELinux requires files to have an extended attribute to define the file
115 type.
116
117 You can see the context of a file using the -Z option to ls
118
119 Policy governs the access confined processes have to these files.
120 SELinux winbind_rpcd policy is very flexible allowing users to setup
121 their winbind_rpcd processes in as secure a method as possible.
122
123 STANDARD FILE CONTEXT
124
125 SELinux defines the file context types for the winbind_rpcd, if you
126 wanted to store files with these types in a diffent paths, you need to
127 execute the semanage command to specify alternate labeling and then use
128 restorecon to put the labels on disk.
129
130 semanage fcontext -a -t winbind_rpcd_var_run_t '/srv/mywin‐
131 bind_rpcd_content(/.*)?'
132 restorecon -R -v /srv/mywinbind_rpcd_content
133
134 Note: SELinux often uses regular expressions to specify labels that
135 match multiple files.
136
137 The following file types are defined for winbind_rpcd:
138
139
140
141 winbind_rpcd_exec_t
142
143 - Set files with the winbind_rpcd_exec_t type, if you want to transi‐
144 tion an executable to the winbind_rpcd_t domain.
145
146
147 Paths:
148 /usr/libexec/samba/rpcd_lsad, /usr/libexec/samba/samba-dcerpcd
149
150
151 winbind_rpcd_var_run_t
152
153 - Set files with the winbind_rpcd_var_run_t type, if you want to store
154 the winbind rpcd files under the /run or /var/run directory.
155
156
157
158 Note: File context can be temporarily modified with the chcon command.
159 If you want to permanently change the file context you need to use the
160 semanage fcontext command. This will modify the SELinux labeling data‐
161 base. You will need to use restorecon to apply the labels.
162
163
165 semanage fcontext can also be used to manipulate default file context
166 mappings.
167
168 semanage permissive can also be used to manipulate whether or not a
169 process type is permissive.
170
171 semanage module can also be used to enable/disable/install/remove pol‐
172 icy modules.
173
174 semanage boolean can also be used to manipulate the booleans
175
176
177 system-config-selinux is a GUI tool available to customize SELinux pol‐
178 icy settings.
