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
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
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
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
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
102
103
104
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
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
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.
