6 unconfined_dbusd_selinux - Security Enhanced Linux Policy for the
7 unconfined_dbusd processes
8
10 Security-Enhanced Linux secures the unconfined_dbusd processes via
11 flexible mandatory access control.
12 The unconfined_dbusd processes execute with the unconfined_dbusd_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep unconfined_dbusd_t
20
24 The unconfined_dbusd_t SELinux type can be entered via the
25 dbusd_exec_t, file_type, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the unconfined_dbusd_t domain are the
29 following:
30 /usr/bin/dbus-daemon(-1)?, /bin/dbus-daemon, /lib/dbus-1/dbus-daemon-
32 launch-helper, /usr/libexec/dbus-daemon-launch-helper,
33 /lib64/dbus-1/dbus-daemon-launch-helper, all files on the system,
34 /dev/cpu/mtrr
35
37 SELinux defines process types (domains) for each process running on the
38 system
39 You can see the context of a process using the -Z option to ps
41 Policy governs the access confined processes have to files. SELinux
43 unconfined_dbusd policy is very flexible allowing users to setup their
44 unconfined_dbusd processes in as secure a method as possible.
45 The following process types are defined for unconfined_dbusd:
47 unconfined_dbusd_t
49 Note: semanage permissive -a unconfined_dbusd_t can be used to make the
51 process type unconfined_dbusd_t permissive. SELinux does not deny
52 access to permissive process types, but the AVC (SELinux denials) mes‐
53 sages are still generated.
54
57 SELinux policy is customizable based on least access required. uncon‐
58 fined_dbusd policy is extremely flexible and has several booleans that
59 allow you to manipulate the policy and run unconfined_dbusd with the
60 tightest access possible.
61 If you want to allow all domains to use other domains file descriptors,
65 you must turn on the allow_domain_fd_use boolean. Enabled by default.
66 setsebool -P allow_domain_fd_use 1
68 If you want to allow unconfined executables to make their heap memory
72 executable. Doing this is a really bad idea. Probably indicates a
73 badly coded executable, but could indicate an attack. This executable
74 should be reported in bugzilla, you must turn on the allow_execheap
75 boolean. Disabled by default.
76 setsebool -P allow_execheap 1
78 If you want to allow unconfined executables to map a memory region as
82 both executable and writable, this is dangerous and the executable
83 should be reported in bugzilla), you must turn on the allow_execmem
84 boolean. Enabled by default.
85 setsebool -P allow_execmem 1
87 If you want to allow all unconfined executables to use libraries
91 requiring text relocation that are not labeled textrel_shlib_t), you
92 must turn on the allow_execmod boolean. Enabled by default.
93 setsebool -P allow_execmod 1
95 If you want to allow unconfined executables to make their stack exe‐
99 cutable. This should never, ever be necessary. Probably indicates a
100 badly coded executable, but could indicate an attack. This executable
101 should be reported in bugzilla), you must turn on the allow_execstack
102 boolean. Enabled by default.
103 setsebool -P allow_execstack 1
105 If you want to allow confined applications to run with kerberos, you
109 must turn on the allow_kerberos boolean. Enabled by default.
110 setsebool -P allow_kerberos 1
112 If you want to allow sysadm to debug or ptrace all processes, you must
116 turn on the allow_ptrace boolean. Disabled by default.
117 setsebool -P allow_ptrace 1
119 If you want to allow system to run with NIS, you must turn on the
123 allow_ypbind boolean. Disabled by default.
124 setsebool -P allow_ypbind 1
126 If you want to allow all domains to have the kernel load modules, you
130 must turn on the domain_kernel_load_modules boolean. Disabled by
131 default.
132 setsebool -P domain_kernel_load_modules 1
134 If you want to allow all domains to execute in fips_mode, you must turn
138 on the fips_mode boolean. Enabled by default.
139 setsebool -P fips_mode 1
141 If you want to enable reading of urandom for all domains, you must turn
145 on the global_ssp boolean. Disabled by default.
146 setsebool -P global_ssp 1
148 If you want to allow certain domains to map low memory in the kernel,
152 you must turn on the mmap_low_allowed boolean. Disabled by default.
153 setsebool -P mmap_low_allowed 1
155 If you want to allow confined applications to use nscd shared memory,
159 you must turn on the nscd_use_shm boolean. Enabled by default.
160 setsebool -P nscd_use_shm 1
162 If you want to boolean to determine whether the system permits loading
166 policy, setting enforcing mode, and changing boolean values. Set this
167 to true and you have to reboot to set it back, you must turn on the
168 secure_mode_policyload boolean. Disabled by default.
169 setsebool -P secure_mode_policyload 1
171 If you want to support NFS home directories, you must turn on the
175 use_nfs_home_dirs boolean. Disabled by default.
176 setsebool -P use_nfs_home_dirs 1
178 If you want to support SAMBA home directories, you must turn on the
182 use_samba_home_dirs boolean. Disabled by default.
183 setsebool -P use_samba_home_dirs 1
185 If you want to support X userspace object manager, you must turn on the
189 xserver_object_manager boolean. Disabled by default.
190 setsebool -P xserver_object_manager 1

196 The SELinux process type unconfined_dbusd_t can manage files labeled
197 with the following file types. The paths listed are the default paths
198 for these file types. Note the processes UID still need to have DAC
199 permissions.
200 file_type
202 all files on the system
204
207 semanage fcontext can also be used to manipulate default file context
208 mappings.
209 semanage permissive can also be used to manipulate whether or not a
211 process type is permissive.
212 semanage module can also be used to enable/disable/install/remove pol‐
214 icy modules.
215 semanage boolean can also be used to manipulate the booleans
217 system-config-selinux is a GUI tool available to customize SELinux pol‐
220 icy settings.
