6 matahari_serviced_selinux - Security Enhanced Linux Policy for the
7 matahari_serviced processes
8
10 Security-Enhanced Linux secures the matahari_serviced processes via
11 flexible mandatory access control.
12 The matahari_serviced processes execute with the matahari_serviced_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 matahari_serviced_t
20
24 The matahari_serviced_t SELinux type can be entered via the file_type,
25 unlabeled_t, proc_type, filesystem_type, mtrr_device_t, sysctl_type,
26 matahari_serviced_exec_t file types.
27 The default entrypoint paths for the matahari_serviced_t domain are the
29 following:
30 all files on the system, /dev/cpu/mtrr, /usr/sbin/matahari-serviced,
32 /usr/sbin/matahari-qmf-serviced, /usr/sbin/matahari-dbus-serviced
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 matahari_serviced policy is very flexible allowing users to setup their
42 matahari_serviced processes in as secure a method as possible.
43 The following process types are defined for matahari_serviced:
45 matahari_serviced_t
47 Note: semanage permissive -a matahari_serviced_t can be used to make
49 the process type matahari_serviced_t permissive. SELinux does not deny
50 access to permissive process types, but the AVC (SELinux denials) mes‐
51 sages are still generated.
52
55 SELinux policy is customizable based on least access required. mata‐
56 hari_serviced policy is extremely flexible and has several booleans
57 that allow you to manipulate the policy and run matahari_serviced with
58 the tightest access possible.
59 If you want to allow all daemons to write corefiles to /, you must turn
63 on the allow_daemons_dump_core boolean. Disabled by default.
64 setsebool -P allow_daemons_dump_core 1
66 If you want to allow all daemons to use tcp wrappers, you must turn on
70 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
71 setsebool -P allow_daemons_use_tcp_wrapper 1
73 If you want to allow all daemons the ability to read/write terminals,
77 you must turn on the allow_daemons_use_tty boolean. Disabled by
78 default.
79 setsebool -P allow_daemons_use_tty 1
81 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the allow_domain_fd_use boolean. Enabled by default.
86 setsebool -P allow_domain_fd_use 1
88 If you want to allow unconfined executables to make their heap memory
92 executable. Doing this is a really bad idea. Probably indicates a
93 badly coded executable, but could indicate an attack. This executable
94 should be reported in bugzilla, you must turn on the allow_execheap
95 boolean. Disabled by default.
96 setsebool -P allow_execheap 1
98 If you want to allow unconfined executables to map a memory region as
102 both executable and writable, this is dangerous and the executable
103 should be reported in bugzilla), you must turn on the allow_execmem
104 boolean. Enabled by default.
105 setsebool -P allow_execmem 1
107 If you want to allow all unconfined executables to use libraries
111 requiring text relocation that are not labeled textrel_shlib_t), you
112 must turn on the allow_execmod boolean. Enabled by default.
113 setsebool -P allow_execmod 1
115 If you want to allow unconfined executables to make their stack exe‐
119 cutable. This should never, ever be necessary. Probably indicates a
120 badly coded executable, but could indicate an attack. This executable
121 should be reported in bugzilla), you must turn on the allow_execstack
122 boolean. Enabled by default.
123 setsebool -P allow_execstack 1
125 If you want to allow sysadm to debug or ptrace all processes, you must
129 turn on the allow_ptrace boolean. Disabled by default.
130 setsebool -P allow_ptrace 1
132 If you want to enable cluster mode for daemons, you must turn on the
136 daemons_enable_cluster_mode boolean. Disabled by default.
137 setsebool -P daemons_enable_cluster_mode 1
139 If you want to allow all domains to have the kernel load modules, you
143 must turn on the domain_kernel_load_modules boolean. Disabled by
144 default.
145 setsebool -P domain_kernel_load_modules 1
147 If you want to allow all domains to execute in fips_mode, you must turn
151 on the fips_mode boolean. Enabled by default.
152 setsebool -P fips_mode 1
154 If you want to enable reading of urandom for all domains, you must turn
158 on the global_ssp boolean. Disabled by default.
159 setsebool -P global_ssp 1
161 If you want to enable support for upstart as the init program, you must
165 turn on the init_upstart boolean. Enabled by default.
166 setsebool -P init_upstart 1
168 If you want to allow certain domains to map low memory in the kernel,
172 you must turn on the mmap_low_allowed boolean. Disabled by default.
173 setsebool -P mmap_low_allowed 1
175 If you want to boolean to determine whether the system permits loading
179 policy, setting enforcing mode, and changing boolean values. Set this
180 to true and you have to reboot to set it back, you must turn on the
181 secure_mode_policyload boolean. Disabled by default.
182 setsebool -P secure_mode_policyload 1
184 If you want to support X userspace object manager, you must turn on the
188 xserver_object_manager boolean. Disabled by default.
189 setsebool -P xserver_object_manager 1

195 The SELinux process type matahari_serviced_t can manage files labeled
196 with the following file types. The paths listed are the default paths
197 for these file types. Note the processes UID still need to have DAC
198 permissions.
199 file_type
201 all files on the system
203
206 SELinux requires files to have an extended attribute to define the file
207 type.
208 You can see the context of a file using the -Z option to ls
210 Policy governs the access confined processes have to these files.
212 SELinux matahari_serviced policy is very flexible allowing users to
213 setup their matahari_serviced processes in as secure a method as possi‐
214 ble.
215 The following file types are defined for matahari_serviced:
217 matahari_serviced_exec_t
221 - Set files with the matahari_serviced_exec_t type, if you want to
223 transition an executable to the matahari_serviced_t domain.
224 Paths:
227 /usr/sbin/matahari-serviced, /usr/sbin/matahari-qmf-serviced,
228 /usr/sbin/matahari-dbus-serviced
229 Note: File context can be temporarily modified with the chcon command.
232 If you want to permanently change the file context you need to use the
233 semanage fcontext command. This will modify the SELinux labeling data‐
234 base. You will need to use restorecon to apply the labels.
235
238 semanage fcontext can also be used to manipulate default file context
239 mappings.
240 semanage permissive can also be used to manipulate whether or not a
242 process type is permissive.
243 semanage module can also be used to enable/disable/install/remove pol‐
245 icy modules.
246 semanage boolean can also be used to manipulate the booleans
248 system-config-selinux is a GUI tool available to customize SELinux pol‐
251 icy settings.
