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 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 setsebool -P authlogin_nsswitch_use_ldap 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. Enabled by default.
73 setsebool -P deny_execmem 1
75 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 setsebool -P fips_mode 1
82 If you want to allow confined applications to run with kerberos, you
86 must turn on the kerberos_enabled boolean. Enabled by default.
87 setsebool -P kerberos_enabled 1
89 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 setsebool -P mmap_low_allowed 1
97 If you want to allow system to run with NIS, you must turn on the
101 nis_enabled boolean. Disabled by default.
102 setsebool -P nis_enabled 1
104 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 setsebool -P nscd_use_shm 1
111 If you want to disable kernel module loading, you must turn on the
115 secure_mode_insmod boolean. Enabled by default.
116 setsebool -P secure_mode_insmod 1
118 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 setsebool -P selinuxuser_execheap 1
128 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 setsebool -P selinuxuser_execstack 1
138
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 file_type
147 all files on the system
149
152 SELinux requires files to have an extended attribute to define the file
153 type.
154 You can see the context of a file using the -Z option to ls
156 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 The following file types are defined for pcp_plugin:
162 pcp_plugin_exec_t
166 - Set files with the pcp_plugin_exec_t type, if you want to transition
168 an executable to the pcp_plugin_t domain.
169 Paths:
172 /var/lib/pcp/pmdas/.*/Remove, /var/lib/pcp/pmdas/.*/Install,
173 /var/lib/pcp/pmdas/.*/Upgrade
174 pcp_plugin_initrc_exec_t
177 - 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 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
190 semanage fcontext can also be used to manipulate default file context
191 mappings.
192 semanage permissive can also be used to manipulate whether or not a
194 process type is permissive.
195 semanage module can also be used to enable/disable/install/remove pol‐
197 icy modules.
198 semanage boolean can also be used to manipulate the booleans
200 system-config-selinux is a GUI tool available to customize SELinux pol‐
203 icy settings.
