6 glance_scrubber_selinux - Security Enhanced Linux Policy for the
7 glance_scrubber processes
8
10 Security-Enhanced Linux secures the glance_scrubber processes via flex‐
11 ible mandatory access control.
12 The glance_scrubber processes execute with the glance_scrubber_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 glance_scrubber_t
20
24 The glance_scrubber_t SELinux type can be entered via the file_type,
25 glance_scrubber_exec_t, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the glance_scrubber_t domain are the
29 following:
30 all files on the system, /usr/bin/glance-scrubber, /dev/cpu/mtrr
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 glance_scrubber policy is very flexible allowing users to setup their
41 glance_scrubber processes in as secure a method as possible.
42 The following process types are defined for glance_scrubber:
44 glance_scrubber_t
46 Note: semanage permissive -a glance_scrubber_t can be used to make the
48 process type glance_scrubber_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required.
55 glance_scrubber policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run glance_scrubber with
57 the tightest access possible.
58 If you want to allow all daemons to write corefiles to /, you must turn
62 on the allow_daemons_dump_core boolean. Disabled by default.
63 setsebool -P allow_daemons_dump_core 1
65 If you want to allow all daemons to use tcp wrappers, you must turn on
69 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
70 setsebool -P allow_daemons_use_tcp_wrapper 1
72 If you want to allow all daemons the ability to read/write terminals,
76 you must turn on the allow_daemons_use_tty boolean. Disabled by
77 default.
78 setsebool -P allow_daemons_use_tty 1
80 If you want to allow all domains to use other domains file descriptors,
84 you must turn on the allow_domain_fd_use boolean. Enabled by default.
85 setsebool -P allow_domain_fd_use 1
87 If you want to allow unconfined executables to make their heap memory
91 executable. Doing this is a really bad idea. Probably indicates a
92 badly coded executable, but could indicate an attack. This executable
93 should be reported in bugzilla, you must turn on the allow_execheap
94 boolean. Disabled by default.
95 setsebool -P allow_execheap 1
97 If you want to allow unconfined executables to map a memory region as
101 both executable and writable, this is dangerous and the executable
102 should be reported in bugzilla), you must turn on the allow_execmem
103 boolean. Enabled by default.
104 setsebool -P allow_execmem 1
106 If you want to allow all unconfined executables to use libraries
110 requiring text relocation that are not labeled textrel_shlib_t), you
111 must turn on the allow_execmod boolean. Enabled by default.
112 setsebool -P allow_execmod 1
114 If you want to allow unconfined executables to make their stack exe‐
118 cutable. This should never, ever be necessary. Probably indicates a
119 badly coded executable, but could indicate an attack. This executable
120 should be reported in bugzilla), you must turn on the allow_execstack
121 boolean. Enabled by default.
122 setsebool -P allow_execstack 1
124 If you want to allow sysadm to debug or ptrace all processes, you must
128 turn on the allow_ptrace boolean. Disabled by default.
129 setsebool -P allow_ptrace 1
131 If you want to enable cluster mode for daemons, you must turn on the
135 daemons_enable_cluster_mode boolean. Disabled by default.
136 setsebool -P daemons_enable_cluster_mode 1
138 If you want to allow all domains to have the kernel load modules, you
142 must turn on the domain_kernel_load_modules boolean. Disabled by
143 default.
144 setsebool -P domain_kernel_load_modules 1
146 If you want to allow all domains to execute in fips_mode, you must turn
150 on the fips_mode boolean. Enabled by default.
151 setsebool -P fips_mode 1
153 If you want to enable reading of urandom for all domains, you must turn
157 on the global_ssp boolean. Disabled by default.
158 setsebool -P global_ssp 1
160 If you want to enable support for upstart as the init program, you must
164 turn on the init_upstart boolean. Enabled by default.
165 setsebool -P init_upstart 1
167 If you want to allow certain domains to map low memory in the kernel,
171 you must turn on the mmap_low_allowed boolean. Disabled by default.
172 setsebool -P mmap_low_allowed 1
174 If you want to boolean to determine whether the system permits loading
178 policy, setting enforcing mode, and changing boolean values. Set this
179 to true and you have to reboot to set it back, you must turn on the
180 secure_mode_policyload boolean. Disabled by default.
181 setsebool -P secure_mode_policyload 1
183 If you want to support X userspace object manager, you must turn on the
187 xserver_object_manager boolean. Disabled by default.
188 setsebool -P xserver_object_manager 1

194 The SELinux process type glance_scrubber_t can manage files labeled
195 with the following file types. The paths listed are the default paths
196 for these file types. Note the processes UID still need to have DAC
197 permissions.
198 file_type
200 all files on the system
202
205 SELinux requires files to have an extended attribute to define the file
206 type.
207 You can see the context of a file using the -Z option to ls
209 Policy governs the access confined processes have to these files.
211 SELinux glance_scrubber policy is very flexible allowing users to setup
212 their glance_scrubber processes in as secure a method as possible.
213 The following file types are defined for glance_scrubber:
215 glance_scrubber_exec_t
219 - Set files with the glance_scrubber_exec_t type, if you want to tran‐
221 sition an executable to the glance_scrubber_t domain.
222 glance_scrubber_initrc_exec_t
226 - Set files with the glance_scrubber_initrc_exec_t type, if you want to
228 transition an executable to the glance_scrubber_initrc_t domain.
229 Note: File context can be temporarily modified with the chcon command.
233 If you want to permanently change the file context you need to use the
234 semanage fcontext command. This will modify the SELinux labeling data‐
235 base. You will need to use restorecon to apply the labels.
236
239 semanage fcontext can also be used to manipulate default file context
240 mappings.
241 semanage permissive can also be used to manipulate whether or not a
243 process type is permissive.
244 semanage module can also be used to enable/disable/install/remove pol‐
246 icy modules.
247 semanage boolean can also be used to manipulate the booleans
249 system-config-selinux is a GUI tool available to customize SELinux pol‐
252 icy settings.
