6 pcp_pmwebd_selinux - Security Enhanced Linux Policy for the pcp_pmwebd
7 processes
8
10 Security-Enhanced Linux secures the pcp_pmwebd processes via flexible
11 mandatory access control.
12
13 The pcp_pmwebd processes execute with the pcp_pmwebd_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep pcp_pmwebd_t
20
21
22
24 The pcp_pmwebd_t SELinux type can be entered via the file_type, unla‐
25 beled_t, proc_type, filesystem_type, mtrr_device_t, sysctl_type,
26 pcp_pmwebd_exec_t file types.
27
28 The default entrypoint paths for the pcp_pmwebd_t domain are the fol‐
29 lowing:
30
31 all files on the system, /dev/cpu/mtrr, /usr/bin/pmwebd,
32 /usr/libexec/pcp/bin/pmwebd
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_pmwebd policy is very flexible allowing users to setup their
42 pcp_pmwebd processes in as secure a method as possible.
43
44 The following process types are defined for pcp_pmwebd:
45
46 pcp_pmwebd_t
47
48 Note: semanage permissive -a pcp_pmwebd_t can be used to make the
49 process type pcp_pmwebd_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_pmwebd policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run pcp_pmwebd with the tightest
58 access possible.

62 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.

88
89
90
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.
96
97 setsebool -P allow_execheap 1
98
99
100
101 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
106 setsebool -P allow_execmem 1
107

114 setsebool -P allow_execmod 1
115
116
117
118 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
124 setsebool -P allow_execstack 1
125
126
127
128 If you want to allow sysadm to debug or ptrace all processes, you must

154
155
156
157 If you want to enable reading of urandom for all domains, you must turn

161
162
163
164 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
167 setsebool -P init_upstart 1
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.
173
174 setsebool -P mmap_low_allowed 1
175
176
177
178 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

193
195 The SELinux process type pcp_pmwebd_t can manage files labeled with the
196 following file types. The paths listed are the default paths for these
197 file types. Note the processes UID still need to have DAC permissions.
198
199 file_type
200
201 all files on the system
202
203
205 SELinux requires files to have an extended attribute to define the file
206 type.
207
208 You can see the context of a file using the -Z option to ls
209
210 Policy governs the access confined processes have to these files.
211 SELinux pcp_pmwebd policy is very flexible allowing users to setup
212 their pcp_pmwebd processes in as secure a method as possible.
213
214 The following file types are defined for pcp_pmwebd:
215
216
217
218 pcp_pmwebd_exec_t
219
220 - Set files with the pcp_pmwebd_exec_t type, if you want to transition
221 an executable to the pcp_pmwebd_t domain.
222
223
224 Paths:
225 /usr/bin/pmwebd, /usr/libexec/pcp/bin/pmwebd
226
227
228 pcp_pmwebd_initrc_exec_t
229
230 - Set files with the pcp_pmwebd_initrc_exec_t type, if you want to
231 transition an executable to the pcp_pmwebd_initrc_t domain.
232
233
234
235 Note: File context can be temporarily modified with the chcon command.
236 If you want to permanently change the file context you need to use the
237 semanage fcontext command. This will modify the SELinux labeling data‐
238 base. You will need to use restorecon to apply the labels.
239
240
242 semanage fcontext can also be used to manipulate default file context
243 mappings.
244
245 semanage permissive can also be used to manipulate whether or not a
246 process type is permissive.
247
248 semanage module can also be used to enable/disable/install/remove pol‐
249 icy modules.
250
251 semanage boolean can also be used to manipulate the booleans
252
253
254 system-config-selinux is a GUI tool available to customize SELinux pol‐
255 icy settings.
