6 pcp_pmcd_selinux - Security Enhanced Linux Policy for the pcp_pmcd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the pcp_pmcd processes via flexible
11 mandatory access control.
12 The pcp_pmcd processes execute with the pcp_pmcd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep pcp_pmcd_t
20
24 The pcp_pmcd_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_pmcd_exec_t file types.
27 The default entrypoint paths for the pcp_pmcd_t domain are the follow‐
29 ing:
30 all files on the system, /dev/cpu/mtrr, /usr/bin/pmcd,
32 /usr/libexec/pcp/bin/pmcd
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_pmcd policy is very flexible allowing users to setup their pcp_pmcd
42 processes in as secure a method as possible.
43 The following process types are defined for pcp_pmcd:
45 pcp_pmcd_t
47 Note: semanage permissive -a pcp_pmcd_t can be used to make the process
49 type pcp_pmcd_t permissive. SELinux does not deny access to permissive
50 process types, but the AVC (SELinux denials) messages are still gener‐
51 ated.
52
55 SELinux policy is customizable based on least access required.
56 pcp_pmcd policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run pcp_pmcd with the tightest
58 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

95 boolean. Disabled by default.
96 setsebool -P allow_execheap 1

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

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

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 allow pcp to bind to all unreserved_ports, you must turn
200 on the pcp_bind_all_unreserved_ports boolean. Disabled by default.
201 setsebool -P pcp_bind_all_unreserved_ports 1
203 If you want to boolean to determine whether the system permits loading
207 policy, setting enforcing mode, and changing boolean values. Set this
208 to true and you have to reboot to set it back, you must turn on the
209 secure_mode_policyload boolean. Disabled by default.

223 The SELinux process type pcp_pmcd_t can manage files labeled with the
224 following file types. The paths listed are the default paths for these
225 file types. Note the processes UID still need to have DAC permissions.
226 file_type
228 all files on the system
230
233 SELinux requires files to have an extended attribute to define the file
234 type.
235 You can see the context of a file using the -Z option to ls
237 Policy governs the access confined processes have to these files.
239 SELinux pcp_pmcd policy is very flexible allowing users to setup their
240 pcp_pmcd processes in as secure a method as possible.
241 The following file types are defined for pcp_pmcd:
243 pcp_pmcd_exec_t
247 - Set files with the pcp_pmcd_exec_t type, if you want to transition an
249 executable to the pcp_pmcd_t domain.
250 Paths:
253 /usr/bin/pmcd, /usr/libexec/pcp/bin/pmcd
254 pcp_pmcd_initrc_exec_t
257 - Set files with the pcp_pmcd_initrc_exec_t type, if you want to tran‐
259 sition an executable to the pcp_pmcd_initrc_t domain.
260 Note: File context can be temporarily modified with the chcon command.
264 If you want to permanently change the file context you need to use the
265 semanage fcontext command. This will modify the SELinux labeling data‐
266 base. You will need to use restorecon to apply the labels.
267
270 semanage fcontext can also be used to manipulate default file context
271 mappings.
272 semanage permissive can also be used to manipulate whether or not a
274 process type is permissive.
275 semanage module can also be used to enable/disable/install/remove pol‐
277 icy modules.
278 semanage boolean can also be used to manipulate the booleans
280 system-config-selinux is a GUI tool available to customize SELinux pol‐
283 icy settings.
