6 pcp_pmlogger_selinux - Security Enhanced Linux Policy for the
7 pcp_pmlogger processes
8
10 Security-Enhanced Linux secures the pcp_pmlogger processes via flexible
11 mandatory access control.
12
13 The pcp_pmlogger processes execute with the pcp_pmlogger_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep pcp_pmlogger_t
20
21
22
24 The pcp_pmlogger_t SELinux type can be entered via the pcp_pmlog‐
25 ger_exec_t, file_type, unlabeled_t, proc_type, filesystem_type,
26 mtrr_device_t, sysctl_type file types.
27
28 The default entrypoint paths for the pcp_pmlogger_t domain are the fol‐
29 lowing:
30
31 /usr/bin/pmlogger, /usr/libexec/pcp/bin/pmlogger, all files on the sys‐
32 tem, /dev/cpu/mtrr
33
35 SELinux defines process types (domains) for each process running on the
36 system
37
38 You can see the context of a process using the -Z option to ps
39
40 Policy governs the access confined processes have to files. SELinux
41 pcp_pmlogger policy is very flexible allowing users to setup their
42 pcp_pmlogger processes in as secure a method as possible.
43
44 The following process types are defined for pcp_pmlogger:
45
46 pcp_pmlogger_t
47
48 Note: semanage permissive -a pcp_pmlogger_t can be used to make the
49 process type pcp_pmlogger_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
53
55 SELinux policy is customizable based on least access required.
56 pcp_pmlogger policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run pcp_pmlogger with the tight‐
58 est access possible.

62 If you want to allow all daemons to write corefiles to /, you must turn

91 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.

97 setsebool -P allow_execheap 1
98

168
169
170
171 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.

202 The SELinux process type pcp_pmlogger_t can manage files labeled with
203 the following file types. The paths listed are the default paths for
204 these file types. Note the processes UID still need to have DAC per‐
205 missions.
206
207 file_type
208
209 all files on the system
210
211
213 SELinux requires files to have an extended attribute to define the file
214 type.
215
216 You can see the context of a file using the -Z option to ls
217
218 Policy governs the access confined processes have to these files.
219 SELinux pcp_pmlogger policy is very flexible allowing users to setup
220 their pcp_pmlogger processes in as secure a method as possible.
221
222 The following file types are defined for pcp_pmlogger:
223
224
225
226 pcp_pmlogger_exec_t
227
228 - Set files with the pcp_pmlogger_exec_t type, if you want to transi‐
229 tion an executable to the pcp_pmlogger_t domain.
230
231
232 Paths:
233 /usr/bin/pmlogger, /usr/libexec/pcp/bin/pmlogger
234
235
236 pcp_pmlogger_initrc_exec_t
237
238 - Set files with the pcp_pmlogger_initrc_exec_t type, if you want to
239 transition an executable to the pcp_pmlogger_initrc_t domain.
240
241
242
243 Note: File context can be temporarily modified with the chcon command.
244 If you want to permanently change the file context you need to use the
245 semanage fcontext command. This will modify the SELinux labeling data‐
246 base. You will need to use restorecon to apply the labels.
247
248
250 semanage fcontext can also be used to manipulate default file context
251 mappings.
252
253 semanage permissive can also be used to manipulate whether or not a
254 process type is permissive.
255
256 semanage module can also be used to enable/disable/install/remove pol‐
257 icy modules.
258
259 semanage boolean can also be used to manipulate the booleans
260
261
262 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
