6 winbind_helper_selinux - Security Enhanced Linux Policy for the win‐
7 bind_helper processes
8
10 Security-Enhanced Linux secures the winbind_helper processes via flexi‐
11 ble mandatory access control.
12 The winbind_helper processes execute with the winbind_helper_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_helper_t
20
24 The winbind_helper_t SELinux type can be entered via the win‐
25 bind_helper_exec_t file type.
26 The default entrypoint paths for the winbind_helper_t domain are the
28 following:
29 /usr/bin/ntlm_auth
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_helper policy is very flexible allowing users to setup their
40 winbind_helper processes in as secure a method as possible.
41 The following process types are defined for winbind_helper:
43 winbind_helper_t
45 Note: semanage permissive -a winbind_helper_t can be used to make the
47 process type winbind_helper_t permissive. SELinux does not deny access
48 to 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_helper policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run winbind_helper with the
56 tightest access possible.
57 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow Apache to use mod_auth_ntlm_winbind, you must turn
68 on the allow_httpd_mod_auth_ntlm_winbind boolean. Disabled by default.
69 setsebool -P allow_httpd_mod_auth_ntlm_winbind 1
71 If you want to allow confined applications to run with kerberos, you
75 must turn on the allow_kerberos boolean. Enabled by default.
76 setsebool -P allow_kerberos 1
78 If you want to allow sysadm to debug or ptrace all processes, you must
82 turn on the allow_ptrace boolean. Disabled by default.
83 setsebool -P allow_ptrace 1
85 If you want to allow system to run with NIS, you must turn on the
89 allow_ypbind boolean. Disabled by default.
90 setsebool -P allow_ypbind 1
92 If you want to allow all domains to have the kernel load modules, you
96 must turn on the domain_kernel_load_modules boolean. Disabled by
97 default.
98 setsebool -P domain_kernel_load_modules 1
100 If you want to allow all domains to execute in fips_mode, you must turn
104 on the fips_mode boolean. Enabled by default.
105 setsebool -P fips_mode 1
107 If you want to enable reading of urandom for all domains, you must turn
111 on the global_ssp boolean. Disabled by default.
112 setsebool -P global_ssp 1
114 If you want to allow confined applications to use nscd shared memory,
118 you must turn on the nscd_use_shm boolean. Enabled by default.
119 setsebool -P nscd_use_shm 1
121
125 The SELinux process type winbind_helper_t can manage files labeled with
126 the following file types. The paths listed are the default paths for
127 these file types. Note the processes UID still need to have DAC per‐
128 missions.
129 initrc_tmp_t
131 mnt_t
134 /mnt(/[^/]*)
136 /mnt(/[^/]*)?
137 /rhev(/[^/]*)?
138 /media(/[^/]*)
139 /media(/[^/]*)?
140 /etc/rhgb(/.*)?
141 /media/.hal-.*
142 /net
143 /afs
144 /rhev
145 /misc
146 tmp_t
148 /tmp
150 /usr/tmp
151 /var/tmp
152 /tmp-inst
153 /var/tmp-inst
154 /var/tmp/vi.recover
155
158 SELinux requires files to have an extended attribute to define the file
159 type.
160 You can see the context of a file using the -Z option to ls
162 Policy governs the access confined processes have to these files.
164 SELinux winbind_helper policy is very flexible allowing users to setup
165 their winbind_helper processes in as secure a method as possible.
166 The following file types are defined for winbind_helper:
168 winbind_helper_exec_t
172 - Set files with the winbind_helper_exec_t type, if you want to transi‐
174 tion an executable to the winbind_helper_t domain.
175 Note: File context can be temporarily modified with the chcon command.
179 If you want to permanently change the file context you need to use the
180 semanage fcontext command. This will modify the SELinux labeling data‐
181 base. You will need to use restorecon to apply the labels.
182
185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
