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 allow users to resolve user passwd entries directly from
62       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
63       gin_nsswitch_use_ldap boolean. Disabled by default.
64
65       setsebool -P authlogin_nsswitch_use_ldap 1
66
67
68
69       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. Enabled by default.
73
74       setsebool -P deny_execmem 1
75
76
77
78       If you want to allow all domains to execute in fips_mode, you must turn
79       on the fips_mode boolean. Enabled by default.
80
81       setsebool -P fips_mode 1
82
83
84
85       If  you  want  to allow confined applications to run with kerberos, you
86       must turn on the kerberos_enabled boolean. Enabled by default.
87
88       setsebool -P kerberos_enabled 1
89
90
91
92       If you want to control the ability to mmap a low area  of  the  address
93       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
94       the mmap_low_allowed boolean. Disabled by default.
95
96       setsebool -P mmap_low_allowed 1
97
98
99
100       If you want to allow system to run with  NIS,  you  must  turn  on  the
101       nis_enabled boolean. Disabled by default.
102
103       setsebool -P nis_enabled 1
104
105
106
107       If  you  want to allow confined applications to use nscd shared memory,
108       you must turn on the nscd_use_shm boolean. Disabled by default.
109
110       setsebool -P nscd_use_shm 1
111
112
113
114       If you want to disable kernel module loading,  you  must  turn  on  the
115       secure_mode_insmod boolean. Enabled by default.
116
117       setsebool -P secure_mode_insmod 1
118
119
120
121       If  you  want to allow unconfined executables to make their heap memory
122       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
123       badly  coded  executable, but could indicate an attack. This executable
124       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
125       uxuser_execheap boolean. Disabled by default.
126
127       setsebool -P selinuxuser_execheap 1
128
129
130
131       If  you  want  to allow unconfined executables to make their stack exe‐
132       cutable.  This should never, ever be necessary.  Probably  indicates  a
133       badly  coded  executable, but could indicate an attack. This executable
134       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
135       stack boolean. Enabled by default.
136
137       setsebool -P selinuxuser_execstack 1
138

MANAGED FILES

142       The SELinux process type pcp_plugin_t can manage files labeled with the
143       following file types.  The paths listed are the default paths for these
144       file types.  Note the processes UID still need to have DAC permissions.
145
146       file_type
147
148            all files on the system
149
150

FILE CONTEXTS

152       SELinux requires files to have an extended attribute to define the file
153       type.
154
155       You can see the context of a file using the -Z option to ls
156
157       Policy governs the access  confined  processes  have  to  these  files.
158       SELinux  pcp_plugin  policy  is  very  flexible allowing users to setup
159       their pcp_plugin processes in as secure a method as possible.
160
161       The following file types are defined for pcp_plugin:
162
163
164
165       pcp_plugin_exec_t
166
167       - Set files with the pcp_plugin_exec_t type, if you want to  transition
168       an executable to the pcp_plugin_t domain.
169
170
171       Paths:
172            /var/lib/pcp/pmdas/.*/Remove,       /var/lib/pcp/pmdas/.*/Install,
173            /var/lib/pcp/pmdas/.*/Upgrade
174
175
176       pcp_plugin_initrc_exec_t
177
178       - Set files with the pcp_plugin_initrc_exec_t  type,  if  you  want  to
179       transition an executable to the pcp_plugin_initrc_t domain.
180
181
182
183       Note:  File context can be temporarily modified with the chcon command.
184       If you want to permanently change the file context you need to use  the
185       semanage fcontext command.  This will modify the SELinux labeling data‐
186       base.  You will need to use restorecon to apply the labels.
187
188

COMMANDS

190       semanage fcontext can also be used to manipulate default  file  context
191       mappings.
192
193       semanage  permissive  can  also  be used to manipulate whether or not a
194       process type is permissive.
195
196       semanage module can also be used to enable/disable/install/remove  pol‐
197       icy modules.
198
199       semanage boolean can also be used to manipulate the booleans
200
201
202       system-config-selinux is a GUI tool available to customize SELinux pol‐
203       icy settings.
