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 deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64 setsebool -P deny_execmem 1
66 If you want to control the ability to mmap a low area of the address
70 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
71 the mmap_low_allowed boolean. Disabled by default.
72 setsebool -P mmap_low_allowed 1
74 If you want to disable kernel module loading, you must turn on the se‐
78 cure_mode_insmod boolean. Enabled by default.
79 setsebool -P secure_mode_insmod 1
81 If you want to allow unconfined executables to make their heap memory
85 executable. Doing this is a really bad idea. Probably indicates a
86 badly coded executable, but could indicate an attack. This executable
87 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
88 echeap boolean. Disabled by default.
89 setsebool -P selinuxuser_execheap 1
91 If you want to allow unconfined executables to make their stack exe‐
95 cutable. This should never, ever be necessary. Probably indicates a
96 badly coded executable, but could indicate an attack. This executable
97 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
98 stack boolean. Enabled by default.
99 setsebool -P selinuxuser_execstack 1

105 The SELinux process type rolekit_t can manage files labeled with the
106 following file types. The paths listed are the default paths for these
107 file types. Note the processes UID still need to have DAC permissions.
108 file_type
110 all files on the system
112
115 SELinux requires files to have an extended attribute to define the file
116 type.
117 You can see the context of a file using the -Z option to ls
119 Policy governs the access confined processes have to these files.
121 SELinux rolekit policy is very flexible allowing users to setup their
122 rolekit processes in as secure a method as possible.
123 STANDARD FILE CONTEXT
125 SELinux defines the file context types for the rolekit, if you wanted
127 to store files with these types in a diffent paths, you need to execute
128 the semanage command to specify alternate labeling and then use re‐
129 storecon to put the labels on disk.
130 semanage fcontext -a -t rolekit_unit_file_t '/srv/myrolekit_con‐
132 tent(/.*)?'
133 restorecon -R -v /srv/myrolekit_content
134 Note: SELinux often uses regular expressions to specify labels that
136 match multiple files.
137 The following file types are defined for rolekit:
139 rolekit_exec_t
143 - Set files with the rolekit_exec_t type, if you want to transition an
145 executable to the rolekit_t domain.
146 rolekit_tmp_t
150 - Set files with the rolekit_tmp_t type, if you want to store rolekit
152 temporary files in the /tmp directories.
153 rolekit_unit_file_t
157 - Set files with the rolekit_unit_file_t type, if you want to treat the
159 files as rolekit unit content.
160 Note: File context can be temporarily modified with the chcon command.
164 If you want to permanently change the file context you need to use the
165 semanage fcontext command. This will modify the SELinux labeling data‐
166 base. You will need to use restorecon to apply the labels.
167
170 semanage fcontext can also be used to manipulate default file context
171 mappings.
172 semanage permissive can also be used to manipulate whether or not a
174 process type is permissive.
175 semanage module can also be used to enable/disable/install/remove pol‐
177 icy modules.
178 semanage boolean can also be used to manipulate the booleans
180 system-config-selinux is a GUI tool available to customize SELinux pol‐
183 icy settings.
