NAME

6       ping_selinux - Security Enhanced Linux Policy for the ping processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the ping processes via flexible manda‐
10       tory access control.
11
12       The ping processes execute with the ping_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep ping_t

21

ENTRYPOINTS

23       The ping_t SELinux type can be entered via the ping_exec_t file type.
24
25       The default entrypoint paths for the ping_t domain are the following:
26
27       /bin/ping.*,  /usr/bin/ping.*,   /usr/sbin/fping.*,   /usr/sbin/hping2,
28       /usr/sbin/send_arp, /usr/lib/heartbeat/send_arp

PROCESS TYPES

31       SELinux defines process types (domains) for each process running on the
32       system
33
34       You can see the context of a process using the -Z option to ps
35
36       Policy governs the access confined processes have  to  files.   SELinux
37       ping  policy  is  very flexible allowing users to setup their ping pro‐
38       cesses in as secure a method as possible.
39
40       The following process types are defined for ping:
41
42       ping_t, pingd_t
43
44       Note: semanage permissive -a ping_t can be used  to  make  the  process
45       type  ping_t  permissive.  SELinux  does  not deny access to permissive
46       process types, but the AVC (SELinux denials) messages are still  gener‐
47       ated.

BOOLEANS

51       SELinux  policy  is  customizable based on least access required.  ping
52       policy is extremely flexible and has several booleans that allow you to
53       manipulate the policy and run ping with the tightest access possible.
54
55
56
57       If you want to allow all domains to execute in fips_mode, you must turn
58       on the fips_mode boolean. Enabled by default.
59
60       setsebool -P fips_mode 1
61
62
63
64       If you want to allow system to run with  NIS,  you  must  turn  on  the
65       nis_enabled boolean. Disabled by default.
66
67       setsebool -P nis_enabled 1
68
69
70
71       If you want to allow confined users the ability to execute the ping and
72       traceroute commands, you must turn on the selinuxuser_ping boolean. En‐
73       abled by default.
74
75       setsebool -P selinuxuser_ping 1
76

78

PORT TYPES

80       SELinux defines port types to represent TCP and UDP ports.
81
82       You  can  see  the  types associated with a port by using the following
83       command:
84
85       semanage port -l
86
87
88       Policy governs the access  confined  processes  have  to  these  ports.
89       SELinux ping policy is very flexible allowing users to setup their ping
90       processes in as secure a method as possible.
91
92       The following port types are defined for ping:
93
94
95       pingd_port_t
96
97
98
99       Default Defined Ports:
100                 tcp 9125
101

MANAGED FILES

103       The SELinux process type ping_t can manage files labeled with the  fol‐
104       lowing  file  types.   The paths listed are the default paths for these
105       file types.  Note the processes UID still need to have DAC permissions.
106
107       krb5_host_rcache_t
108
109            /var/tmp/krb5_0.rcache2
110            /var/cache/krb5rcache(/.*)?
111            /var/tmp/nfs_0
112            /var/tmp/DNS_25
113            /var/tmp/host_0
114            /var/tmp/imap_0
115            /var/tmp/HTTP_23
116            /var/tmp/HTTP_48
117            /var/tmp/ldap_55
118            /var/tmp/ldap_487
119            /var/tmp/ldapmap1_0

121

FILE CONTEXTS

123       SELinux requires files to have an extended attribute to define the file
124       type.
125
126       You can see the context of a file using the -Z option to ls
127
128       Policy  governs  the  access  confined  processes  have to these files.
129       SELinux ping policy is very flexible allowing users to setup their ping
130       processes in as secure a method as possible.
131
132       STANDARD FILE CONTEXT
133
134       SELinux  defines  the file context types for the ping, if you wanted to
135       store files with these types in a different paths, you need to  execute
136       the  semanage  command  to  specify alternate labeling and then use re‐
137       storecon to put the labels on disk.
138
139       semanage fcontext -a -t ping_exec_t '/srv/ping/content(/.*)?'
140       restorecon -R -v /srv/myping_content
141
142       Note: SELinux often uses regular expressions  to  specify  labels  that
143       match multiple files.
144
145       The following file types are defined for ping:
146
147
148
149       ping_exec_t
150
151       - Set files with the ping_exec_t type, if you want to transition an ex‐
152       ecutable to the ping_t domain.
153
154
155       Paths:
156            /bin/ping.*, /usr/bin/ping.*, /usr/sbin/fping.*, /usr/sbin/hping2,
157            /usr/sbin/send_arp, /usr/lib/heartbeat/send_arp
158
159
160       pingd_etc_t
161
162       - Set files with the pingd_etc_t type, if you want to store pingd files
163       in the /etc directories.
164
165
166
167       pingd_exec_t
168
169       - Set files with the pingd_exec_t type, if you want  to  transition  an
170       executable to the pingd_t domain.
171
172
173
174       pingd_initrc_exec_t
175
176       -  Set  files with the pingd_initrc_exec_t type, if you want to transi‐
177       tion an executable to the pingd_initrc_t domain.
178
179
180
181       pingd_modules_t
182
183       - Set files with the pingd_modules_t type, if you  want  to  treat  the
184       files as pingd modules.
185
186
187
188       Note:  File context can be temporarily modified with the chcon command.
189       If you want to permanently change the file context you need to use  the
190       semanage fcontext command.  This will modify the SELinux labeling data‐
191       base.  You will need to use restorecon to apply the labels.
192
193

COMMANDS

195       semanage fcontext can also be used to manipulate default  file  context
196       mappings.
197
198       semanage  permissive  can  also  be used to manipulate whether or not a
199       process type is permissive.
200
201       semanage module can also be used to enable/disable/install/remove  pol‐
202       icy modules.
203
204       semanage port can also be used to manipulate the port definitions
205
206       semanage boolean can also be used to manipulate the booleans
207
208
209       system-config-selinux is a GUI tool available to customize SELinux pol‐
210       icy settings.
