6 dcc_client_selinux - Security Enhanced Linux Policy for the dcc_client
7 processes
8
10 Security-Enhanced Linux secures the dcc_client processes via flexible
11 mandatory access control.
12 The dcc_client processes execute with the dcc_client_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep dcc_client_t
20
24 The dcc_client_t SELinux type can be entered via the dcc_client_exec_t
25 file type.
26 The default entrypoint paths for the dcc_client_t domain are the fol‐
28 lowing:
29 /usr/bin/dccproc
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 dcc_client policy is very flexible allowing users to setup their
40 dcc_client processes in as secure a method as possible.
41 The following process types are defined for dcc_client:
43 dcc_client_t
45 Note: semanage permissive -a dcc_client_t can be used to make the
47 process type dcc_client_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 dcc_client policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dcc_client with the tightest
56 access possible.
57 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to allow sysadm to debug or ptrace all processes, you must
75 turn on the allow_ptrace boolean. Disabled by default.
76 setsebool -P allow_ptrace 1
78 If you want to allow system to run with NIS, you must turn on the
82 allow_ypbind boolean. Disabled by default.
83 setsebool -P allow_ypbind 1
85 If you want to allow all domains to have the kernel load modules, you
89 must turn on the domain_kernel_load_modules boolean. Disabled by
90 default.
91 setsebool -P domain_kernel_load_modules 1
93 If you want to allow all domains to execute in fips_mode, you must turn
97 on the fips_mode boolean. Enabled by default.
98 setsebool -P fips_mode 1
100 If you want to enable reading of urandom for all domains, you must turn
104 on the global_ssp boolean. Disabled by default.
105 setsebool -P global_ssp 1
107 If you want to allow confined applications to use nscd shared memory,
111 you must turn on the nscd_use_shm boolean. Enabled by default.
112 setsebool -P nscd_use_shm 1
114
118 The SELinux process type dcc_client_t can manage files labeled with the
119 following file types. The paths listed are the default paths for these
120 file types. Note the processes UID still need to have DAC permissions.
121 dcc_client_map_t
123 /etc/dcc/map
125 /var/dcc/map
126 /var/lib/dcc/map

166 SELinux requires files to have an extended attribute to define the file
167 type.
168 You can see the context of a file using the -Z option to ls
170 Policy governs the access confined processes have to these files.
172 SELinux dcc_client policy is very flexible allowing users to setup
173 their dcc_client processes in as secure a method as possible.
174 STANDARD FILE CONTEXT
176 SELinux defines the file context types for the dcc_client, if you
178 wanted to store files with these types in a diffent paths, you need to
179 execute the semanage command to sepecify alternate labeling and then
180 use restorecon to put the labels on disk.
181 semanage fcontext -a -t dcc_client_tmp_t '/srv/mydcc_client_con‐
183 tent(/.*)?'
184 restorecon -R -v /srv/mydcc_client_content
185 Note: SELinux often uses regular expressions to specify labels that
187 match multiple files.
188 The following file types are defined for dcc_client:
190 dcc_client_exec_t
194 - Set files with the dcc_client_exec_t type, if you want to transition
196 an executable to the dcc_client_t domain.
197 dcc_client_map_t
201 - Set files with the dcc_client_map_t type, if you want to treat the
203 files as dcc client map data.
204 Paths:
207 /etc/dcc/map, /var/dcc/map, /var/lib/dcc/map, /var/run/dcc/map
208 dcc_client_tmp_t
211 - Set files with the dcc_client_tmp_t type, if you want to store dcc
213 client temporary files in the /tmp directories.
214 Note: File context can be temporarily modified with the chcon command.
218 If you want to permanently change the file context you need to use the
219 semanage fcontext command. This will modify the SELinux labeling data‐
220 base. You will need to use restorecon to apply the labels.
221
224 semanage fcontext can also be used to manipulate default file context
225 mappings.
226 semanage permissive can also be used to manipulate whether or not a
228 process type is permissive.
229 semanage module can also be used to enable/disable/install/remove pol‐
231 icy modules.
232 semanage boolean can also be used to manipulate the booleans
234 system-config-selinux is a GUI tool available to customize SELinux pol‐
237 icy settings.
