6 iceauth_selinux - Security Enhanced Linux Policy for the iceauth pro‐
7 cesses
8
10 Security-Enhanced Linux secures the iceauth processes via flexible
11 mandatory access control.
12 The iceauth processes execute with the iceauth_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep iceauth_t
20
24 The iceauth_t SELinux type can be entered via the iceauth_exec_t file
25 type.
26 The default entrypoint paths for the iceauth_t domain are the follow‐
28 ing:
29 /usr/bin/iceauth, /usr/X11R6/bin/iceauth
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 iceauth policy is very flexible allowing users to setup their iceauth
40 processes in as secure a method as possible.
41 The following process types are defined for iceauth:
43 iceauth_t
45 Note: semanage permissive -a iceauth_t can be used to make the process
47 type iceauth_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. iceauth
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run iceauth with the tightest access possi‐
56 ble.
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 sysadm to debug or ptrace all processes, you must
68 turn on the allow_ptrace boolean. Disabled by default.
69 setsebool -P allow_ptrace 1
71 If you want to allow all domains to have the kernel load modules, you
75 must turn on the domain_kernel_load_modules boolean. Disabled by
76 default.
77 setsebool -P domain_kernel_load_modules 1
79 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84 setsebool -P fips_mode 1
86 If you want to enable reading of urandom for all domains, you must turn
90 on the global_ssp boolean. Disabled by default.
91 setsebool -P global_ssp 1
93 If you want to support NFS home directories, you must turn on the
97 use_nfs_home_dirs boolean. Disabled by default.
98 setsebool -P use_nfs_home_dirs 1
100 If you want to support SAMBA home directories, you must turn on the
104 use_samba_home_dirs boolean. Disabled by default.
105 setsebool -P use_samba_home_dirs 1
107
111 The SELinux process type iceauth_t can manage files labeled with the
112 following file types. The paths listed are the default paths for these
113 file types. Note the processes UID still need to have DAC permissions.
114 cifs_t
116 iceauth_home_t
119 /home/[^/]*/.DCOP.*
121 /home/[^/]*/.ICEauthority.*
122 /home/staff/.DCOP.*
123 /home/staff/.ICEauthority.*
124 initrc_tmp_t

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 iceauth policy is very flexible allowing users to setup their
163 iceauth processes in as secure a method as possible.
164 STANDARD FILE CONTEXT
166 SELinux defines the file context types for the iceauth, if you wanted
168 to 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 iceauth_home_t '/srv/myiceauth_content(/.*)?'
173 restorecon -R -v /srv/myiceauth_content
174 Note: SELinux often uses regular expressions to specify labels that
176 match multiple files.
177 The following file types are defined for iceauth:
179 iceauth_exec_t
183 - Set files with the iceauth_exec_t type, if you want to transition an
185 executable to the iceauth_t domain.
186 Paths:
189 /usr/bin/iceauth, /usr/X11R6/bin/iceauth
190 iceauth_home_t
193 - Set files with the iceauth_home_t type, if you want to store iceauth
195 files in the users home directory.
196 Paths:
199 /home/[^/]*/.DCOP.*, /home/[^/]*/.ICEauthority.*,
200 /home/staff/.DCOP.*, /home/staff/.ICEauthority.*
201 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
