6 cobblerd_selinux - Security Enhanced Linux Policy for the cobblerd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cobblerd processes via flexible
11 mandatory access control.
12 The cobblerd processes execute with the cobblerd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep cobblerd_t
20
24 The cobblerd_t SELinux type can be entered via the cobblerd_exec_t file
25 type.
26 The default entrypoint paths for the cobblerd_t domain are the follow‐
28 ing:
29 /usr/bin/cobblerd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 cobblerd policy is very flexible allowing users to setup their cobblerd
40 processes in as secure a method as possible.
41 The following process types are defined for cobblerd:
43 cobblerd_t
45 Note: semanage permissive -a cobblerd_t can be used to make the process
47 type cobblerd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. cob‐
54 blerd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run cobblerd with the tightest access
56 possible.
57 If you want to determine whether Cobbler can connect to the network us‐
61 ing TCP, you must turn on the cobbler_can_network_connect boolean. Dis‐
62 abled by default.
63 setsebool -P cobbler_can_network_connect 1
65 If you want to determine whether Cobbler can access cifs file systems,
69 you must turn on the cobbler_use_cifs boolean. Disabled by default.
70 setsebool -P cobbler_use_cifs 1
72 If you want to determine whether Cobbler can access nfs file systems,
76 you must turn on the cobbler_use_nfs boolean. Disabled by default.
77 setsebool -P cobbler_use_nfs 1
79 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84 setsebool -P fips_mode 1
86
90 SELinux defines port types to represent TCP and UDP ports.
91 You can see the types associated with a port by using the following
93 command:
94 semanage port -l
96 Policy governs the access confined processes have to these ports.
99 SELinux cobblerd policy is very flexible allowing users to setup their
100 cobblerd processes in as secure a method as possible.
101 The following port types are defined for cobblerd:
103 cobbler_port_t
106 Default Defined Ports:
110 tcp 25151
111
113 The SELinux process type cobblerd_t can manage files labeled with the
114 following file types. The paths listed are the default paths for these
115 file types. Note the processes UID still need to have DAC permissions.

247 SELinux requires files to have an extended attribute to define the file
248 type.
249 You can see the context of a file using the -Z option to ls
251 Policy governs the access confined processes have to these files.
253 SELinux cobblerd policy is very flexible allowing users to setup their
254 cobblerd processes in as secure a method as possible.
255 The following file types are defined for cobblerd:
257 cobblerd_exec_t
261 - Set files with the cobblerd_exec_t type, if you want to transition an
263 executable to the cobblerd_t domain.
264 cobblerd_initrc_exec_t
268 - Set files with the cobblerd_initrc_exec_t type, if you want to tran‐
270 sition an executable to the cobblerd_initrc_t domain.
271 Note: File context can be temporarily modified with the chcon command.
275 If you want to permanently change the file context you need to use the
276 semanage fcontext command. This will modify the SELinux labeling data‐
277 base. You will need to use restorecon to apply the labels.
278
281 If you want to share files with multiple domains (Apache, FTP, rsync,
282 Samba), you can set a file context of public_content_t and public_con‐
283 tent_rw_t. These context allow any of the above domains to read the
284 content. If you want a particular domain to write to the public_con‐
285 tent_rw_t domain, you must set the appropriate boolean.
286 Allow cobblerd servers to read the /var/cobblerd directory by adding
288 the public_content_t file type to the directory and by restoring the
289 file type.
290 semanage fcontext -a -t public_content_t "/var/cobblerd(/.*)?"
292 restorecon -F -R -v /var/cobblerd
293 Allow cobblerd servers to read and write /var/cobblerd/incoming by
295 adding the public_content_rw_t type to the directory and by restoring
296 the file type. You also need to turn on the cobblerd_anon_write bool‐
297 ean.
298 semanage fcontext -a -t public_content_rw_t "/var/cobblerd/incom‐
300 ing(/.*)?"
301 restorecon -F -R -v /var/cobblerd/incoming
302 setsebool -P cobblerd_anon_write 1
303 If you want to determine whether Cobbler can modify public files used
306 for public file transfer services., you must turn on the cob‐
307 bler_anon_write boolean.
308 setsebool -P cobbler_anon_write 1
310
313 semanage fcontext can also be used to manipulate default file context
314 mappings.
315 semanage permissive can also be used to manipulate whether or not a
317 process type is permissive.
318 semanage module can also be used to enable/disable/install/remove pol‐
320 icy modules.
321 semanage port can also be used to manipulate the port definitions
323 semanage boolean can also be used to manipulate the booleans
325 system-config-selinux is a GUI tool available to customize SELinux pol‐
328 icy settings.
