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 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 For example:
18 ps -eZ | grep pcp_pmlogger_t
20
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 The default entrypoint paths for the pcp_pmlogger_t domain are the fol‐
29 lowing:
30 /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 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_pmlogger policy is very flexible allowing users to setup their
42 pcp_pmlogger processes in as secure a method as possible.
43 The following process types are defined for pcp_pmlogger:
45 pcp_pmlogger_t
47 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
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.
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

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 allow pcp to bind to all unreserved_ports, you must turn
179 on the pcp_bind_all_unreserved_ports boolean. Disabled by default.
180 setsebool -P pcp_bind_all_unreserved_ports 1
182 If you want to boolean to determine whether the system permits loading
186 policy, setting enforcing mode, and changing boolean values. Set this
187 to true and you have to reboot to set it back, you must turn on the
188 secure_mode_policyload boolean. Disabled by default.
189 setsebool -P secure_mode_policyload 1
191 If you want to support X userspace object manager, you must turn on the
195 xserver_object_manager boolean. Disabled by default.
196 setsebool -P xserver_object_manager 1

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 file_type
208 all files on the system
210
213 SELinux requires files to have an extended attribute to define the file
214 type.
215 You can see the context of a file using the -Z option to ls
217 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 The following file types are defined for pcp_pmlogger:
223 pcp_pmlogger_exec_t
227 - 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 Paths:
233 /usr/bin/pmlogger, /usr/libexec/pcp/bin/pmlogger
234 pcp_pmlogger_initrc_exec_t
237 - 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 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
250 semanage fcontext can also be used to manipulate default file context
251 mappings.
252 semanage permissive can also be used to manipulate whether or not a
254 process type is permissive.
255 semanage module can also be used to enable/disable/install/remove pol‐
257 icy modules.
258 semanage boolean can also be used to manipulate the booleans
260 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
