6 smoltclient_selinux - Security Enhanced Linux Policy for the smolt‐
7 client processes
8
10 Security-Enhanced Linux secures the smoltclient processes via flexible
11 mandatory access control.
12 The smoltclient processes execute with the smoltclient_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 smoltclient_t
20
24 The smoltclient_t SELinux type can be entered via the smolt‐
25 client_exec_t file type.
26 The default entrypoint paths for the smoltclient_t domain are the fol‐
28 lowing:
29 /usr/share/smolt/client/sendProfile.py
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 smoltclient policy is very flexible allowing users to setup their
40 smoltclient processes in as secure a method as possible.
41 The following process types are defined for smoltclient:
43 smoltclient_t
45 Note: semanage permissive -a smoltclient_t can be used to make the
47 process type smoltclient_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. smolt‐
54 client policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run smoltclient 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 deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139
143 The SELinux process type smoltclient_t can manage files labeled with
144 the following file types. The paths listed are the default paths for
145 these file types. Note the processes UID still need to have DAC per‐
146 missions.
147 smoltclient_tmp_t
149
153 SELinux requires files to have an extended attribute to define the file
154 type.
155 You can see the context of a file using the -Z option to ls
157 Policy governs the access confined processes have to these files.
159 SELinux smoltclient policy is very flexible allowing users to setup
160 their smoltclient processes in as secure a method as possible.
161 STANDARD FILE CONTEXT
163 SELinux defines the file context types for the smoltclient, if you
165 wanted to store files with these types in a diffent paths, you need to
166 execute the semanage command to sepecify alternate labeling and then
167 use restorecon to put the labels on disk.
168 semanage fcontext -a -t smoltclient_tmp_t '/srv/mysmoltclient_con‐
170 tent(/.*)?'
171 restorecon -R -v /srv/mysmoltclient_content
172 Note: SELinux often uses regular expressions to specify labels that
174 match multiple files.
175 The following file types are defined for smoltclient:
177 smoltclient_exec_t
181 - Set files with the smoltclient_exec_t type, if you want to transition
183 an executable to the smoltclient_t domain.
184 smoltclient_tmp_t
188 - Set files with the smoltclient_tmp_t type, if you want to store
190 smoltclient temporary files in the /tmp directories.
191 Note: File context can be temporarily modified with the chcon command.
195 If you want to permanently change the file context you need to use the
196 semanage fcontext command. This will modify the SELinux labeling data‐
197 base. You will need to use restorecon to apply the labels.
198
201 semanage fcontext can also be used to manipulate default file context
202 mappings.
203 semanage permissive can also be used to manipulate whether or not a
205 process type is permissive.
206 semanage module can also be used to enable/disable/install/remove pol‐
208 icy modules.
209 semanage boolean can also be used to manipulate the booleans
211 system-config-selinux is a GUI tool available to customize SELinux pol‐
214 icy settings.
