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 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 For example:
18 ps -eZ | grep winbind_rpcd_t
20
24 The winbind_rpcd_t SELinux type can be entered via the win‐
25 bind_rpcd_exec_t file type.
26 The default entrypoint paths for the winbind_rpcd_t domain are the fol‐
28 lowing:
29 /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 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 winbind_rpcd policy is very flexible allowing users to setup their win‐
40 bind_rpcd processes in as secure a method as possible.
41 The following process types are defined for winbind_rpcd:
43 winbind_rpcd_t
45 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
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 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 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71 If you want to allow samba to act as the domain controller, add users,
75 groups and change passwords, you must turn on the samba_domain_con‐
76 troller boolean. Disabled by default.
77 setsebool -P samba_domain_controller 1
79 If you want to allow samba and winbind-rpcd to share users home direc‐
83 tories, you must turn on the samba_enable_home_dirs boolean. Disabled
84 by default.
85 setsebool -P samba_enable_home_dirs 1
87
91 The SELinux process type winbind_rpcd_t can manage files labeled with
92 the following file types. The paths listed are the default paths for
93 these file types. Note the processes UID still need to have DAC per‐
94 missions.

100 /var/log/tallylog.*

147 SELinux requires files to have an extended attribute to define the file
148 type.
149 You can see the context of a file using the -Z option to ls
151 Policy governs the access confined processes have to these files.
153 SELinux winbind_rpcd policy is very flexible allowing users to setup
154 their winbind_rpcd processes in as secure a method as possible.
155 STANDARD FILE CONTEXT
157 SELinux defines the file context types for the winbind_rpcd, if you
159 wanted to store files with these types in a different paths, you need
160 to execute the semanage command to specify alternate labeling and then
161 use restorecon to put the labels on disk.
162 semanage fcontext -a -t winbind_rpcd_exec_t '/srv/winbind_rpcd/con‐
164 tent(/.*)?'
165 restorecon -R -v /srv/mywinbind_rpcd_content
166 Note: SELinux often uses regular expressions to specify labels that
168 match multiple files.
169 The following file types are defined for winbind_rpcd:
171 winbind_rpcd_exec_t
175 - Set files with the winbind_rpcd_exec_t type, if you want to transi‐
177 tion an executable to the winbind_rpcd_t domain.
178 Paths:
181 /usr/libexec/samba/rpcd_lsad, /usr/libexec/samba/samba-dcerpcd
182 winbind_rpcd_tmp_t
185 - Set files with the winbind_rpcd_tmp_t type, if you want to store win‐
187 bind rpcd temporary files in the /tmp directories.
188 winbind_rpcd_var_run_t
192 - Set files with the winbind_rpcd_var_run_t type, if you want to store
194 the winbind rpcd files under the /run or /var/run directory.
195 Note: File context can be temporarily modified with the chcon command.
199 If you want to permanently change the file context you need to use the
200 semanage fcontext command. This will modify the SELinux labeling data‐
201 base. You will need to use restorecon to apply the labels.
202
205 semanage fcontext can also be used to manipulate default file context
206 mappings.
207 semanage permissive can also be used to manipulate whether or not a
209 process type is permissive.
210 semanage module can also be used to enable/disable/install/remove pol‐
212 icy modules.
213 semanage boolean can also be used to manipulate the booleans
215 system-config-selinux is a GUI tool available to customize SELinux pol‐
218 icy settings.
