6 rhcd_selinux - Security Enhanced Linux Policy for the rhcd processes
7
9 Security-Enhanced Linux secures the rhcd processes via flexible manda‐
10 tory access control.
11 The rhcd processes execute with the rhcd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep rhcd_t
19
23 The rhcd_t SELinux type can be entered via the rhcd_exec_t file type.
24 The default entrypoint paths for the rhcd_t domain are the following:
26 /usr/sbin/rhcd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 rhcd policy is very flexible allowing users to setup their rhcd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for rhcd:
40 rhcd_t
42 Note: semanage permissive -a rhcd_t can be used to make the process
44 type rhcd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. rhcd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run rhcd with the tightest access possible.
53 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59 setsebool -P daemons_dontaudit_scheduling 1
61 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66 setsebool -P fips_mode 1
68
72 The SELinux process type rhcd_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

114 SELinux requires files to have an extended attribute to define the file
115 type.
116 You can see the context of a file using the -Z option to ls
118 Policy governs the access confined processes have to these files.
120 SELinux rhcd policy is very flexible allowing users to setup their rhcd
121 processes in as secure a method as possible.
122 STANDARD FILE CONTEXT
124 SELinux defines the file context types for the rhcd, if you wanted to
126 store files with these types in a different paths, you need to execute
127 the semanage command to specify alternate labeling and then use re‐
128 storecon to put the labels on disk.
129 semanage fcontext -a -t rhcd_exec_t '/srv/rhcd/content(/.*)?'
131 restorecon -R -v /srv/myrhcd_content
132 Note: SELinux often uses regular expressions to specify labels that
134 match multiple files.
135 The following file types are defined for rhcd:
137 rhcd_exec_t
141 - Set files with the rhcd_exec_t type, if you want to transition an ex‐
143 ecutable to the rhcd_t domain.
144 rhcd_tmp_t
148 - Set files with the rhcd_tmp_t type, if you want to store rhcd tempo‐
150 rary files in the /tmp directories.
151 rhcd_tmpfs_t
155 - Set files with the rhcd_tmpfs_t type, if you want to store rhcd files
157 on a tmpfs file system.
158 rhcd_unit_file_t
162 - Set files with the rhcd_unit_file_t type, if you want to treat the
164 files as rhcd unit content.
165 rhcd_var_log_t
169 - Set files with the rhcd_var_log_t type, if you want to treat the data
171 as rhcd var log data, usually stored under the /var/log directory.
172 rhcd_var_run_t
176 - Set files with the rhcd_var_run_t type, if you want to store the rhcd
178 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.
