6 rolekit_selinux - Security Enhanced Linux Policy for the rolekit pro‐
7 cesses
8
10 Security-Enhanced Linux secures the rolekit processes via flexible
11 mandatory access control.
12 The rolekit processes execute with the rolekit_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep rolekit_t
20
24 The rolekit_t SELinux type can be entered via the rolekit_exec_t file
25 type.
26 The default entrypoint paths for the rolekit_t domain are the follow‐
28 ing:
29 /usr/sbin/roled
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 rolekit policy is very flexible allowing users to setup their rolekit
40 processes in as secure a method as possible.
41 The following process types are defined for rolekit:
43 rolekit_t
45 Note: semanage permissive -a rolekit_t can be used to make the process
47 type rolekit_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. rolekit
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run rolekit with the tightest access possi‐
56 ble.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Disabled by default.
72 setsebool -P deny_execmem 1
74 If you want to control the ability to mmap a low area of the address
78 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
79 the mmap_low_allowed boolean. Disabled by default.
80 setsebool -P mmap_low_allowed 1
82 If you want to allow system to run with NIS, you must turn on the
86 nis_enabled boolean. Disabled by default.
87 setsebool -P nis_enabled 1
89 If you want to disable kernel module loading, you must turn on the se‐
93 cure_mode_insmod boolean. Disabled by default.
94 setsebool -P secure_mode_insmod 1
96 If you want to allow unconfined executables to make their heap memory
100 executable. Doing this is a really bad idea. Probably indicates a
101 badly coded executable, but could indicate an attack. This executable
102 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
103 echeap boolean. Disabled by default.
104 setsebool -P selinuxuser_execheap 1
106 If you want to allow unconfined executables to make their stack exe‐
110 cutable. This should never, ever be necessary. Probably indicates a
111 badly coded executable, but could indicate an attack. This executable
112 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
113 stack boolean. Enabled by default.
114 setsebool -P selinuxuser_execstack 1
116
120 The SELinux process type rolekit_t can manage files labeled with the
121 following file types. The paths listed are the default paths for these
122 file types. Note the processes UID still need to have DAC permissions.
123 file_type
125 all files on the system
127
130 SELinux requires files to have an extended attribute to define the file
131 type.
132 You can see the context of a file using the -Z option to ls
134 Policy governs the access confined processes have to these files.
136 SELinux rolekit policy is very flexible allowing users to setup their
137 rolekit processes in as secure a method as possible.
138 STANDARD FILE CONTEXT
140 SELinux defines the file context types for the rolekit, if you wanted
142 to store files with these types in a different paths, you need to exe‐
143 cute the semanage command to specify alternate labeling and then use
144 restorecon to put the labels on disk.
145 semanage fcontext -a -t rolekit_exec_t '/srv/rolekit/content(/.*)?'
147 restorecon -R -v /srv/myrolekit_content
148 Note: SELinux often uses regular expressions to specify labels that
150 match multiple files.
151 The following file types are defined for rolekit:
153 rolekit_exec_t
157 - Set files with the rolekit_exec_t type, if you want to transition an
159 executable to the rolekit_t domain.
160 rolekit_tmp_t
164 - Set files with the rolekit_tmp_t type, if you want to store rolekit
166 temporary files in the /tmp directories.
167 rolekit_unit_file_t
171 - Set files with the rolekit_unit_file_t type, if you want to treat the
173 files as rolekit unit content.
174 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192 semanage boolean can also be used to manipulate the booleans
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
197 icy settings.
