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 users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 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 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1
93
97 The SELinux process type dcc_client_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.
100 dcc_client_map_t
102 /etc/dcc/map
104 /var/dcc/map
105 /var/lib/dcc/map
106 /var/run/dcc/map
107 dcc_client_tmp_t
109 dcc_var_t
112 /etc/dcc(/.*)?
114 /var/dcc(/.*)?
115 /var/lib/dcc(/.*)?
116
119 SELinux requires files to have an extended attribute to define the file
120 type.
121 You can see the context of a file using the -Z option to ls
123 Policy governs the access confined processes have to these files.
125 SELinux dcc_client policy is very flexible allowing users to setup
126 their dcc_client processes in as secure a method as possible.
127 STANDARD FILE CONTEXT
129 SELinux defines the file context types for the dcc_client, if you
131 wanted to store files with these types in a diffent paths, you need to
132 execute the semanage command to sepecify alternate labeling and then
133 use restorecon to put the labels on disk.
134 semanage fcontext -a -t dcc_client_tmp_t '/srv/mydcc_client_con‐
136 tent(/.*)?'
137 restorecon -R -v /srv/mydcc_client_content
138 Note: SELinux often uses regular expressions to specify labels that
140 match multiple files.
141 The following file types are defined for dcc_client:
143 dcc_client_exec_t
147 - Set files with the dcc_client_exec_t type, if you want to transition
149 an executable to the dcc_client_t domain.
150 dcc_client_map_t
154 - Set files with the dcc_client_map_t type, if you want to treat the
156 files as dcc client map data.
157 Paths:
160 /etc/dcc/map, /var/dcc/map, /var/lib/dcc/map, /var/run/dcc/map
161 dcc_client_tmp_t
164 - Set files with the dcc_client_tmp_t type, if you want to store dcc
166 client temporary files in the /tmp directories.
167 Note: File context can be temporarily modified with the chcon command.
171 If you want to permanently change the file context you need to use the
172 semanage fcontext command. This will modify the SELinux labeling data‐
173 base. You will need to use restorecon to apply the labels.
174
177 semanage fcontext can also be used to manipulate default file context
178 mappings.
179 semanage permissive can also be used to manipulate whether or not a
181 process type is permissive.
182 semanage module can also be used to enable/disable/install/remove pol‐
184 icy modules.
185 semanage boolean can also be used to manipulate the booleans
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
190 icy settings.
