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 daemons_dump_core boolean. Disabled by default.
62 setsebool -P daemons_dump_core 1

82 you must turn on the daemons_use_tty boolean. Disabled by default.
83 setsebool -P daemons_use_tty 1
85 If you want to deny any process from ptracing or debugging any other
89 processes, you must turn on the deny_ptrace boolean. Enabled by
90 default.
91 setsebool -P deny_ptrace 1
93 If you want to allow any process to mmap any file on system with
97 attribute file_type, you must turn on the domain_can_mmap_files bool‐
98 ean. Enabled by default.
99 setsebool -P domain_can_mmap_files 1
101 If you want to allow all domains write to kmsg_device, while kernel is
105 executed with systemd.log_target=kmsg parameter, you must turn on the
106 domain_can_write_kmsg boolean. Disabled by default.
107 setsebool -P domain_can_write_kmsg 1
109 If you want to allow all domains to use other domains file descriptors,
113 you must turn on the domain_fd_use boolean. Enabled by default.
114 setsebool -P domain_fd_use 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

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

187 SELinux requires files to have an extended attribute to define the file
188 type.
189 You can see the context of a file using the -Z option to ls
191 Policy governs the access confined processes have to these files.
193 SELinux uml_switch policy is very flexible allowing users to setup
194 their uml_switch processes in as secure a method as possible.
195 STANDARD FILE CONTEXT
197 SELinux defines the file context types for the uml_switch, if you
199 wanted to store files with these types in a diffent paths, you need to
200 execute the semanage command to sepecify alternate labeling and then
201 use restorecon to put the labels on disk.
202 semanage fcontext -a -t uml_switch_var_run_t '/srv/myuml_switch_con‐
204 tent(/.*)?'
205 restorecon -R -v /srv/myuml_switch_content
206 Note: SELinux often uses regular expressions to specify labels that
208 match multiple files.
209 The following file types are defined for uml_switch:
211 uml_switch_exec_t
215 - Set files with the uml_switch_exec_t type, if you want to transition
217 an executable to the uml_switch_t domain.
218 uml_switch_var_run_t
222 - Set files with the uml_switch_var_run_t type, if you want to store
224 the uml switch files under the /run or /var/run directory.
225 Note: File context can be temporarily modified with the chcon command.
229 If you want to permanently change the file context you need to use the
230 semanage fcontext command. This will modify the SELinux labeling data‐
231 base. You will need to use restorecon to apply the labels.
232
235 semanage fcontext can also be used to manipulate default file context
236 mappings.
237 semanage permissive can also be used to manipulate whether or not a
239 process type is permissive.
240 semanage module can also be used to enable/disable/install/remove pol‐
242 icy modules.
243 semanage boolean can also be used to manipulate the booleans
245 system-config-selinux is a GUI tool available to customize SELinux pol‐
248 icy settings.
