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 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 smoltclient_t can manage files labeled with
119 the following file types. The paths listed are the default paths for
120 these file types. Note the processes UID still need to have DAC per‐
121 missions.
122 initrc_tmp_t
124 mnt_t
127 /mnt(/[^/]*)
129 /mnt(/[^/]*)?
130 /rhev(/[^/]*)?
131 /media(/[^/]*)
132 /media(/[^/]*)?
133 /etc/rhgb(/.*)?
134 /media/.hal-.*
135 /net
136 /afs
137 /rhev
138 /misc
139 smoltclient_tmp_t
141 tmp_t
144 /tmp
146 /usr/tmp
147 /var/tmp
148 /tmp-inst
149 /var/tmp-inst
150 /var/tmp/vi.recover
151
154 SELinux requires files to have an extended attribute to define the file
155 type.
156 You can see the context of a file using the -Z option to ls
158 Policy governs the access confined processes have to these files.
160 SELinux smoltclient policy is very flexible allowing users to setup
161 their smoltclient processes in as secure a method as possible.
162 STANDARD FILE CONTEXT
164 SELinux defines the file context types for the smoltclient, if you
166 wanted to store files with these types in a diffent paths, you need to
167 execute the semanage command to sepecify alternate labeling and then
168 use restorecon to put the labels on disk.
169 semanage fcontext -a -t smoltclient_tmp_t '/srv/mysmoltclient_con‐
171 tent(/.*)?'
172 restorecon -R -v /srv/mysmoltclient_content
173 Note: SELinux often uses regular expressions to specify labels that
175 match multiple files.
176 The following file types are defined for smoltclient:
178 smoltclient_exec_t
182 - Set files with the smoltclient_exec_t type, if you want to transition
184 an executable to the smoltclient_t domain.
185 smoltclient_tmp_t
189 - Set files with the smoltclient_tmp_t type, if you want to store
191 smoltclient temporary files in the /tmp directories.
192 Note: File context can be temporarily modified with the chcon command.
196 If you want to permanently change the file context you need to use the
197 semanage fcontext command. This will modify the SELinux labeling data‐
198 base. You will need to use restorecon to apply the labels.
199
202 semanage fcontext can also be used to manipulate default file context
203 mappings.
204 semanage permissive can also be used to manipulate whether or not a
206 process type is permissive.
207 semanage module can also be used to enable/disable/install/remove pol‐
209 icy modules.
210 semanage boolean can also be used to manipulate the booleans
212 system-config-selinux is a GUI tool available to customize SELinux pol‐
215 icy settings.
