NAME

6       pcp_plugin_selinux  - Security Enhanced Linux Policy for the pcp_plugin
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the pcp_plugin processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep pcp_plugin_t
20
21
22

ENTRYPOINTS

24       The  pcp_plugin_t SELinux type can be entered via the pcp_plugin_exec_t
25       file type.
26
27       The default entrypoint paths for the pcp_plugin_t domain are  the  fol‐
28       lowing:
29
30       /var/lib/pcp/pmdas/.*/Remove,            /var/lib/pcp/pmdas/.*/Install,
31       /var/lib/pcp/pmdas/.*/Upgrade
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       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
43       The following process types are defined for pcp_plugin:
44
45       pcp_plugin_t
46
47       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
52

BOOLEANS

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
59
60
61       If you want to deny user domains applications to map a memory region as
62       both executable and writable, this  is  dangerous  and  the  executable
63       should be reported in bugzilla, you must turn on the deny_execmem bool‐
64       ean. Enabled by default.
65
66       setsebool -P deny_execmem 1
67
68
69
70       If you want to control the ability to mmap a low area  of  the  address
71       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
72       the mmap_low_allowed boolean. Disabled by default.
73
74       setsebool -P mmap_low_allowed 1
75
76
77
78       If you want to disable kernel module loading, you must turn on the  se‐
79       cure_mode_insmod boolean. Enabled by default.
80
81       setsebool -P secure_mode_insmod 1
82
83
84
85       If  you  want to allow unconfined executables to make their heap memory
86       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
87       badly  coded  executable, but could indicate an attack. This executable
88       should be reported in bugzilla, you must turn  on  the  selinuxuser_ex‐
89       echeap boolean. Disabled by default.
90
91       setsebool -P selinuxuser_execheap 1
92
93
94
95       If  you  want  to allow unconfined executables to make their stack exe‐
96       cutable.  This should never, ever be necessary.  Probably  indicates  a
97       badly  coded  executable, but could indicate an attack. This executable
98       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
99       stack boolean. Enabled by default.
100
101       setsebool -P selinuxuser_execstack 1

MANAGED FILES

106       The SELinux process type pcp_plugin_t can manage files labeled with the
107       following file types.  The paths listed are the default paths for these
108       file types.  Note the processes UID still need to have DAC permissions.
109
110       file_type
111
112            all files on the system
113
114

FILE CONTEXTS

116       SELinux requires files to have an extended attribute to define the file
117       type.
118
119       You can see the context of a file using the -Z option to ls
120
121       Policy governs the access  confined  processes  have  to  these  files.
122       SELinux  pcp_plugin  policy  is  very  flexible allowing users to setup
123       their pcp_plugin processes in as secure a method as possible.
124
125       The following file types are defined for pcp_plugin:
126
127
128
129       pcp_plugin_exec_t
130
131       - Set files with the pcp_plugin_exec_t type, if you want to  transition
132       an executable to the pcp_plugin_t domain.
133
134
135       Paths:
136            /var/lib/pcp/pmdas/.*/Remove,       /var/lib/pcp/pmdas/.*/Install,
137            /var/lib/pcp/pmdas/.*/Upgrade
138
139
140       pcp_plugin_initrc_exec_t
141
142       - Set files with the pcp_plugin_initrc_exec_t  type,  if  you  want  to
143       transition an executable to the pcp_plugin_initrc_t domain.
144
145
146
147       Note:  File context can be temporarily modified with the chcon command.
148       If you want to permanently change the file context you need to use  the
149       semanage fcontext command.  This will modify the SELinux labeling data‐
150       base.  You will need to use restorecon to apply the labels.
151
152

COMMANDS

154       semanage fcontext can also be used to manipulate default  file  context
155       mappings.
156
157       semanage  permissive  can  also  be used to manipulate whether or not a
158       process type is permissive.
159
160       semanage module can also be used to enable/disable/install/remove  pol‐
161       icy modules.
162
163       semanage boolean can also be used to manipulate the booleans
164
165
166       system-config-selinux is a GUI tool available to customize SELinux pol‐
167       icy settings.
