6 pcp_plugin_selinux - Security Enhanced Linux Policy for the pcp_plugin
7 processes
8
10 Security-Enhanced Linux secures the pcp_plugin processes via flexible
11 mandatory access control.
12 The pcp_plugin processes execute with the pcp_plugin_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_plugin_t
20
24 The pcp_plugin_t SELinux type can be entered via the pcp_plugin_exec_t
25 file type.
26 The default entrypoint paths for the pcp_plugin_t domain are the fol‐
28 lowing:
29 /var/lib/pcp/pmdas/.*/Remove, /var/lib/pcp/pmdas/.*/Install,
31 /var/lib/pcp/pmdas/.*/Upgrade
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 pcp_plugin policy is very flexible allowing users to setup their
41 pcp_plugin processes in as secure a method as possible.
42 The following process types are defined for pcp_plugin:
44 pcp_plugin_t
46 Note: semanage permissive -a pcp_plugin_t can be used to make the
48 process type pcp_plugin_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required.
55 pcp_plugin policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run pcp_plugin with the tightest
57 access possible.
58 If you want to dontaudit all daemons scheduling requests (setsched,
62 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
63 Enabled by default.
64 setsebool -P daemons_dontaudit_scheduling 1
66 If you want to deny user domains applications to map a memory region as
70 both executable and writable, this is dangerous and the executable
71 should be reported in bugzilla, you must turn on the deny_execmem bool‐
72 ean. Disabled by default.
73 setsebool -P deny_execmem 1
75 If you want to control the ability to mmap a low area of the address
79 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
80 the mmap_low_allowed boolean. Disabled by default.
81 setsebool -P mmap_low_allowed 1
83 If you want to allow system to run with NIS, you must turn on the
87 nis_enabled boolean. Disabled by default.
88 setsebool -P nis_enabled 1
90 If you want to disable kernel module loading, you must turn on the se‐
94 cure_mode_insmod boolean. Disabled by default.
95 setsebool -P secure_mode_insmod 1
97 If you want to allow unconfined executables to make their heap memory
101 executable. Doing this is a really bad idea. Probably indicates a
102 badly coded executable, but could indicate an attack. This executable
103 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
104 echeap boolean. Disabled by default.
105 setsebool -P selinuxuser_execheap 1
107 If you want to allow unconfined executables to make their stack exe‐
111 cutable. This should never, ever be necessary. Probably indicates a
112 badly coded executable, but could indicate an attack. This executable
113 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
114 stack boolean. Enabled by default.
115 setsebool -P selinuxuser_execstack 1

121 The SELinux process type pcp_plugin_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.
124 file_type
126 all files on the system
128
131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux pcp_plugin policy is very flexible allowing users to setup
138 their pcp_plugin processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the pcp_plugin, if you
143 wanted to store files with these types in a different paths, you need
144 to execute the semanage command to specify alternate labeling and then
145 use restorecon to put the labels on disk.
146 semanage fcontext -a -t pcp_plugin_exec_t '/srv/pcp_plugin/con‐
148 tent(/.*)?'
149 restorecon -R -v /srv/mypcp_plugin_content
150 Note: SELinux often uses regular expressions to specify labels that
152 match multiple files.
153 The following file types are defined for pcp_plugin:
155 pcp_plugin_exec_t
159 - Set files with the pcp_plugin_exec_t type, if you want to transition
161 an executable to the pcp_plugin_t domain.
162 Paths:
165 /var/lib/pcp/pmdas/.*/Remove, /var/lib/pcp/pmdas/.*/Install,
166 /var/lib/pcp/pmdas/.*/Upgrade
167 pcp_plugin_initrc_exec_t
170 - Set files with the pcp_plugin_initrc_exec_t type, if you want to
172 transition an executable to the pcp_plugin_initrc_t domain.
173 Note: File context can be temporarily modified with the chcon command.
177 If you want to permanently change the file context you need to use the
178 semanage fcontext command. This will modify the SELinux labeling data‐
179 base. You will need to use restorecon to apply the labels.
180
183 semanage fcontext can also be used to manipulate default file context
184 mappings.
185 semanage permissive can also be used to manipulate whether or not a
187 process type is permissive.
188 semanage module can also be used to enable/disable/install/remove pol‐
190 icy modules.
191 semanage boolean can also be used to manipulate the booleans
193 system-config-selinux is a GUI tool available to customize SELinux pol‐
196 icy settings.
