6 uml_switch_selinux - Security Enhanced Linux Policy for the uml_switch
7 processes
8
10 Security-Enhanced Linux secures the uml_switch processes via flexible
11 mandatory access control.
12 The uml_switch processes execute with the uml_switch_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 uml_switch_t
20
24 The uml_switch_t SELinux type can be entered via the uml_switch_exec_t
25 file type.
26 The default entrypoint paths for the uml_switch_t domain are the fol‐
28 lowing:
29 /usr/bin/uml_switch
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 uml_switch policy is very flexible allowing users to setup their
40 uml_switch processes in as secure a method as possible.
41 The following process types are defined for uml_switch:
43 uml_switch_t
45 Note: semanage permissive -a uml_switch_t can be used to make the
47 process type uml_switch_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 uml_switch policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run uml_switch with the tightest
56 access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.

83 you must turn on the allow_domain_fd_use boolean. Enabled by default.

86 If you want to allow sysadm to debug or ptrace all processes, you must
90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to enable cluster mode for daemons, you must turn on the
97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type uml_switch_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

200 SELinux requires files to have an extended attribute to define the file
201 type.
202 You can see the context of a file using the -Z option to ls
204 Policy governs the access confined processes have to these files.
206 SELinux uml_switch policy is very flexible allowing users to setup
207 their uml_switch processes in as secure a method as possible.
208 STANDARD FILE CONTEXT
210 SELinux defines the file context types for the uml_switch, if you
212 wanted to store files with these types in a diffent paths, you need to
213 execute the semanage command to sepecify alternate labeling and then
214 use restorecon to put the labels on disk.
215 semanage fcontext -a -t uml_switch_var_run_t '/srv/myuml_switch_con‐
217 tent(/.*)?'
218 restorecon -R -v /srv/myuml_switch_content
219 Note: SELinux often uses regular expressions to specify labels that
221 match multiple files.
222 The following file types are defined for uml_switch:
224 uml_switch_exec_t
228 - Set files with the uml_switch_exec_t type, if you want to transition
230 an executable to the uml_switch_t domain.
231 uml_switch_var_run_t
235 - Set files with the uml_switch_var_run_t type, if you want to store
237 the uml switch files under the /run or /var/run directory.
238 Note: File context can be temporarily modified with the chcon command.
242 If you want to permanently change the file context you need to use the
243 semanage fcontext command. This will modify the SELinux labeling data‐
244 base. You will need to use restorecon to apply the labels.
245
248 semanage fcontext can also be used to manipulate default file context
249 mappings.
250 semanage permissive can also be used to manipulate whether or not a
252 process type is permissive.
253 semanage module can also be used to enable/disable/install/remove pol‐
255 icy modules.
256 semanage boolean can also be used to manipulate the booleans
258 system-config-selinux is a GUI tool available to customize SELinux pol‐
261 icy settings.
