6 cmirrord_selinux - Security Enhanced Linux Policy for the cmirrord pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cmirrord processes via flexible
11 mandatory access control.
12 The cmirrord processes execute with the cmirrord_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 cmirrord_t
20
24 The cmirrord_t SELinux type can be entered via the cmirrord_exec_t file
25 type.
26 The default entrypoint paths for the cmirrord_t domain are the follow‐
28 ing:
29 /usr/sbin/cmirrord
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 cmirrord policy is very flexible allowing users to setup their cmirrord
40 processes in as secure a method as possible.
41 The following process types are defined for cmirrord:
43 cmirrord_t
45 Note: semanage permissive -a cmirrord_t can be used to make the process
47 type cmirrord_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. cmir‐
54 rord policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run cmirrord with the tightest access
56 possible.
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 allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72
76 The SELinux process type cmirrord_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

128 SELinux requires files to have an extended attribute to define the file
129 type.
130 You can see the context of a file using the -Z option to ls
132 Policy governs the access confined processes have to these files.
134 SELinux cmirrord policy is very flexible allowing users to setup their
135 cmirrord processes in as secure a method as possible.
136 STANDARD FILE CONTEXT
138 SELinux defines the file context types for the cmirrord, if you wanted
140 to store files with these types in a different paths, you need to exe‐
141 cute the semanage command to specify alternate labeling and then use
142 restorecon to put the labels on disk.
143 semanage fcontext -a -t cmirrord_exec_t '/srv/cmirrord/content(/.*)?'
145 restorecon -R -v /srv/mycmirrord_content
146 Note: SELinux often uses regular expressions to specify labels that
148 match multiple files.
149 The following file types are defined for cmirrord:
151 cmirrord_exec_t
155 - Set files with the cmirrord_exec_t type, if you want to transition an
157 executable to the cmirrord_t domain.
158 cmirrord_initrc_exec_t
162 - Set files with the cmirrord_initrc_exec_t type, if you want to tran‐
164 sition an executable to the cmirrord_initrc_t domain.
165 cmirrord_tmpfs_t
169 - Set files with the cmirrord_tmpfs_t type, if you want to store cmir‐
171 rord files on a tmpfs file system.
172 cmirrord_var_run_t
176 - Set files with the cmirrord_var_run_t type, if you want to store the
178 cmirrord files under the /run or /var/run directory.
179 Note: File context can be temporarily modified with the chcon command.
183 If you want to permanently change the file context you need to use the
184 semanage fcontext command. This will modify the SELinux labeling data‐
185 base. You will need to use restorecon to apply the labels.
186
189 semanage fcontext can also be used to manipulate default file context
190 mappings.
191 semanage permissive can also be used to manipulate whether or not a
193 process type is permissive.
194 semanage module can also be used to enable/disable/install/remove pol‐
196 icy modules.
197 semanage boolean can also be used to manipulate the booleans
199 system-config-selinux is a GUI tool available to customize SELinux pol‐
202 icy settings.
