6 pcp_pmproxy_selinux - Security Enhanced Linux Policy for the
7 pcp_pmproxy processes
8
10 Security-Enhanced Linux secures the pcp_pmproxy processes via flexible
11 mandatory access control.
12 The pcp_pmproxy processes execute with the pcp_pmproxy_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep pcp_pmproxy_t
20
24 The pcp_pmproxy_t SELinux type can be entered via the file_type, unla‐
25 beled_t, proc_type, filesystem_type, pcp_pmproxy_exec_t, mtrr_device_t,
26 sysctl_type file types.
27 The default entrypoint paths for the pcp_pmproxy_t domain are the fol‐
29 lowing:
30 all files on the system, /usr/bin/pmproxy,
32 /usr/libexec/pcp/bin/pmproxy, /dev/cpu/mtrr
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 pcp_pmproxy policy is very flexible allowing users to setup their
42 pcp_pmproxy processes in as secure a method as possible.
43 The following process types are defined for pcp_pmproxy:
45 pcp_pmproxy_t
47 Note: semanage permissive -a pcp_pmproxy_t can be used to make the
49 process type pcp_pmproxy_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 pcp_pmproxy policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run pcp_pmproxy with the tight‐
58 est access possible.

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

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 confined applications to run with kerberos, you
129 must turn on the allow_kerberos boolean. Enabled by default.
130 setsebool -P allow_kerberos 1
132 If you want to allow sysadm to debug or ptrace all processes, you must
136 turn on the allow_ptrace boolean. Disabled by default.
137 setsebool -P allow_ptrace 1

143 allow_ypbind boolean. Disabled by default.
144 setsebool -P allow_ypbind 1
146 If you want to enable cluster mode for daemons, you must turn on the
150 daemons_enable_cluster_mode boolean. Disabled by default.
151 setsebool -P daemons_enable_cluster_mode 1
153 If you want to allow all domains to have the kernel load modules, you
157 must turn on the domain_kernel_load_modules boolean. Disabled by
158 default.
159 setsebool -P domain_kernel_load_modules 1
161 If you want to allow all domains to execute in fips_mode, you must turn
165 on the fips_mode boolean. Enabled by default.
166 setsebool -P fips_mode 1
168 If you want to enable reading of urandom for all domains, you must turn
172 on the global_ssp boolean. Disabled by default.
173 setsebool -P global_ssp 1
175 If you want to enable support for upstart as the init program, you must
179 turn on the init_upstart boolean. Enabled by default.
180 setsebool -P init_upstart 1
182 If you want to allow certain domains to map low memory in the kernel,
186 you must turn on the mmap_low_allowed boolean. Disabled by default.
187 setsebool -P mmap_low_allowed 1
189 If you want to allow confined applications to use nscd shared memory,
193 you must turn on the nscd_use_shm boolean. Enabled by default.
194 setsebool -P nscd_use_shm 1
196 If you want to boolean to determine whether the system permits loading
200 policy, setting enforcing mode, and changing boolean values. Set this
201 to true and you have to reboot to set it back, you must turn on the
202 secure_mode_policyload boolean. Disabled by default.
203 setsebool -P secure_mode_policyload 1
205 If you want to support X userspace object manager, you must turn on the
209 xserver_object_manager boolean. Disabled by default.
210 setsebool -P xserver_object_manager 1

216 The SELinux process type pcp_pmproxy_t can manage files labeled with
217 the following file types. The paths listed are the default paths for
218 these file types. Note the processes UID still need to have DAC per‐
219 missions.
220 file_type
222 all files on the system
224
227 SELinux requires files to have an extended attribute to define the file
228 type.
229 You can see the context of a file using the -Z option to ls
231 Policy governs the access confined processes have to these files.
233 SELinux pcp_pmproxy policy is very flexible allowing users to setup
234 their pcp_pmproxy processes in as secure a method as possible.
235 The following file types are defined for pcp_pmproxy:
237 pcp_pmproxy_exec_t
241 - Set files with the pcp_pmproxy_exec_t type, if you want to transition
243 an executable to the pcp_pmproxy_t domain.
244 Paths:
247 /usr/bin/pmproxy, /usr/libexec/pcp/bin/pmproxy
248 pcp_pmproxy_initrc_exec_t
251 - Set files with the pcp_pmproxy_initrc_exec_t type, if you want to
253 transition an executable to the pcp_pmproxy_initrc_t domain.
254 Note: File context can be temporarily modified with the chcon command.
258 If you want to permanently change the file context you need to use the
259 semanage fcontext command. This will modify the SELinux labeling data‐
260 base. You will need to use restorecon to apply the labels.
261
264 semanage fcontext can also be used to manipulate default file context
265 mappings.
266 semanage permissive can also be used to manipulate whether or not a
268 process type is permissive.
269 semanage module can also be used to enable/disable/install/remove pol‐
271 icy modules.
272 semanage boolean can also be used to manipulate the booleans
274 system-config-selinux is a GUI tool available to customize SELinux pol‐
277 icy settings.
