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 allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60
64 The SELinux process type rhcd_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.

106 SELinux requires files to have an extended attribute to define the file
107 type.
108 You can see the context of a file using the -Z option to ls
110 Policy governs the access confined processes have to these files.
112 SELinux rhcd policy is very flexible allowing users to setup their rhcd
113 processes in as secure a method as possible.
114 STANDARD FILE CONTEXT
116 SELinux defines the file context types for the rhcd, if you wanted to
118 store files with these types in a diffent paths, you need to execute
119 the semanage command to specify alternate labeling and then use re‐
120 storecon to put the labels on disk.
121 semanage fcontext -a -t rhcd_var_run_t '/srv/myrhcd_content(/.*)?'
123 restorecon -R -v /srv/myrhcd_content
124 Note: SELinux often uses regular expressions to specify labels that
126 match multiple files.
127 The following file types are defined for rhcd:
129 rhcd_exec_t
133 - Set files with the rhcd_exec_t type, if you want to transition an ex‐
135 ecutable to the rhcd_t domain.
136 rhcd_tmp_t
140 - Set files with the rhcd_tmp_t type, if you want to store rhcd tempo‐
142 rary files in the /tmp directories.
143 rhcd_tmpfs_t
147 - Set files with the rhcd_tmpfs_t type, if you want to store rhcd files
149 on a tmpfs file system.
150 rhcd_unit_file_t
154 - Set files with the rhcd_unit_file_t type, if you want to treat the
156 files as rhcd unit content.
157 rhcd_var_log_t
161 - Set files with the rhcd_var_log_t type, if you want to treat the data
163 as rhcd var log data, usually stored under the /var/log directory.
164 rhcd_var_run_t
168 - Set files with the rhcd_var_run_t type, if you want to store the rhcd
170 files under the /run or /var/run directory.
171 Note: File context can be temporarily modified with the chcon command.
175 If you want to permanently change the file context you need to use the
176 semanage fcontext command. This will modify the SELinux labeling data‐
177 base. You will need to use restorecon to apply the labels.
178
181 semanage fcontext can also be used to manipulate default file context
182 mappings.
183 semanage permissive can also be used to manipulate whether or not a
185 process type is permissive.
186 semanage module can also be used to enable/disable/install/remove pol‐
188 icy modules.
189 semanage boolean can also be used to manipulate the booleans
191 system-config-selinux is a GUI tool available to customize SELinux pol‐
194 icy settings.
