6 cdcc_selinux - Security Enhanced Linux Policy for the cdcc processes
7
9 Security-Enhanced Linux secures the cdcc processes via flexible manda‐
10 tory access control.
11 The cdcc processes execute with the cdcc_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 cdcc_t
19
23 The cdcc_t SELinux type can be entered via the cdcc_exec_t file type.
24 The default entrypoint paths for the cdcc_t domain are the following:
26 /usr/bin/cdcc
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 cdcc policy is very flexible allowing users to setup their cdcc pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for cdcc:
40 cdcc_t
42 Note: semanage permissive -a cdcc_t can be used to make the process
44 type cdcc_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. cdcc
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run cdcc with the tightest access possible.
53 If you want to allow all domains to use other domains file descriptors,
57 you must turn on the allow_domain_fd_use boolean. Enabled by default.
58 setsebool -P allow_domain_fd_use 1
60 If you want to allow confined applications to run with kerberos, you
64 must turn on the allow_kerberos boolean. Enabled by default.
65 setsebool -P allow_kerberos 1
67 If you want to allow sysadm to debug or ptrace all processes, you must
71 turn on the allow_ptrace boolean. Disabled by default.
72 setsebool -P allow_ptrace 1
74 If you want to allow system to run with NIS, you must turn on the
78 allow_ypbind boolean. Disabled by default.
79 setsebool -P allow_ypbind 1
81 If you want to allow all domains to have the kernel load modules, you
85 must turn on the domain_kernel_load_modules boolean. Disabled by
86 default.
87 setsebool -P domain_kernel_load_modules 1
89 If you want to allow all domains to execute in fips_mode, you must turn
93 on the fips_mode boolean. Enabled by default.
94 setsebool -P fips_mode 1
96 If you want to enable reading of urandom for all domains, you must turn
100 on the global_ssp boolean. Disabled by default.
101 setsebool -P global_ssp 1
103 If you want to allow confined applications to use nscd shared memory,
107 you must turn on the nscd_use_shm boolean. Enabled by default.
108 setsebool -P nscd_use_shm 1

114 The SELinux process type cdcc_t can manage files labeled with the fol‐
115 lowing file types. The paths listed are the default paths for these
116 file types. Note the processes UID still need to have DAC permissions.

156 SELinux requires files to have an extended attribute to define the file
157 type.
158 You can see the context of a file using the -Z option to ls
160 Policy governs the access confined processes have to these files.
162 SELinux cdcc policy is very flexible allowing users to setup their cdcc
163 processes in as secure a method as possible.
164 STANDARD FILE CONTEXT
166 SELinux defines the file context types for the cdcc, if you wanted to
168 store files with these types in a diffent paths, you need to execute
169 the semanage command to sepecify alternate labeling and then use
170 restorecon to put the labels on disk.
171 semanage fcontext -a -t cdcc_tmp_t '/srv/mycdcc_content(/.*)?'
173 restorecon -R -v /srv/mycdcc_content
174 Note: SELinux often uses regular expressions to specify labels that
176 match multiple files.
177 The following file types are defined for cdcc:
179 cdcc_exec_t
183 - Set files with the cdcc_exec_t type, if you want to transition an
185 executable to the cdcc_t domain.
186 cdcc_tmp_t
190 - Set files with the cdcc_tmp_t type, if you want to store cdcc tempo‐
192 rary files in the /tmp directories.
193 Note: File context can be temporarily modified with the chcon command.
197 If you want to permanently change the file context you need to use the
198 semanage fcontext command. This will modify the SELinux labeling data‐
199 base. You will need to use restorecon to apply the labels.
200
203 semanage fcontext can also be used to manipulate default file context
204 mappings.
205 semanage permissive can also be used to manipulate whether or not a
207 process type is permissive.
208 semanage module can also be used to enable/disable/install/remove pol‐
210 icy modules.
211 semanage boolean can also be used to manipulate the booleans
213 system-config-selinux is a GUI tool available to customize SELinux pol‐
216 icy settings.
