6 user_dbusd_selinux - Security Enhanced Linux Policy for the user_dbusd
7 processes
8
10 Security-Enhanced Linux secures the user_dbusd processes via flexible
11 mandatory access control.
12 The user_dbusd processes execute with the user_dbusd_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep user_dbusd_t
20
24 The user_dbusd_t SELinux type can be entered via the dbusd_exec_t file
25 type.
26 The default entrypoint paths for the user_dbusd_t domain are the fol‐
28 lowing:
29 /usr/bin/dbus-daemon(-1)?, /bin/dbus-daemon, /lib/dbus-1/dbus-daemon-
31 launch-helper, /usr/lib/dbus-1/dbus-daemon-launch-helper,
32 /usr/libexec/dbus-1/dbus-daemon-launch-helper
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 user_dbusd policy is very flexible allowing users to setup their
42 user_dbusd processes in as secure a method as possible.
43 The following process types are defined for user_dbusd:
45 user_dbusd_t
47 Note: semanage permissive -a user_dbusd_t can be used to make the
49 process type user_dbusd_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 user_dbusd policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run user_dbusd with the tightest
58 access possible.
59 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65 setsebool -P authlogin_nsswitch_use_ldap 1
67 If you want to deny any process from ptracing or debugging any other
71 processes, you must turn on the deny_ptrace boolean. Enabled by
72 default.
73 setsebool -P deny_ptrace 1
75 If you want to allow any process to mmap any file on system with
79 attribute file_type, you must turn on the domain_can_mmap_files bool‐
80 ean. Enabled by default.
81 setsebool -P domain_can_mmap_files 1
83 If you want to allow all domains write to kmsg_device, while kernel is
87 executed with systemd.log_target=kmsg parameter, you must turn on the
88 domain_can_write_kmsg boolean. Disabled by default.
89 setsebool -P domain_can_write_kmsg 1
91 If you want to allow all domains to use other domains file descriptors,
95 you must turn on the domain_fd_use boolean. Enabled by default.
96 setsebool -P domain_fd_use 1
98 If you want to allow all domains to have the kernel load modules, you
102 must turn on the domain_kernel_load_modules boolean. Disabled by
103 default.
104 setsebool -P domain_kernel_load_modules 1
106 If you want to allow all domains to execute in fips_mode, you must turn
110 on the fips_mode boolean. Enabled by default.
111 setsebool -P fips_mode 1
113 If you want to enable reading of urandom for all domains, you must turn
117 on the global_ssp boolean. Disabled by default.
118 setsebool -P global_ssp 1
120 If you want to allow confined applications to run with kerberos, you
124 must turn on the kerberos_enabled boolean. Enabled by default.
125 setsebool -P kerberos_enabled 1
127 If you want to allow system to run with NIS, you must turn on the
131 nis_enabled boolean. Disabled by default.
132 setsebool -P nis_enabled 1
134 If you want to allow confined applications to use nscd shared memory,
138 you must turn on the nscd_use_shm boolean. Disabled by default.
139 setsebool -P nscd_use_shm 1
141 If you want to support ecryptfs home directories, you must turn on the
145 use_ecryptfs_home_dirs boolean. Disabled by default.
146 setsebool -P use_ecryptfs_home_dirs 1
148 If you want to support fusefs home directories, you must turn on the
152 use_fusefs_home_dirs boolean. Disabled by default.
153 setsebool -P use_fusefs_home_dirs 1
155 If you want to support NFS home directories, you must turn on the
159 use_nfs_home_dirs boolean. Disabled by default.
160 setsebool -P use_nfs_home_dirs 1
162 If you want to support SAMBA home directories, you must turn on the
166 use_samba_home_dirs boolean. Disabled by default.
167 setsebool -P use_samba_home_dirs 1

173 The SELinux process type user_dbusd_t can manage files labeled with the
174 following file types. The paths listed are the default paths for these
175 file types. Note the processes UID still need to have DAC permissions.

181 /home/[^/]+/.Private(/.*)?

219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
