6 xm_selinux - Security Enhanced Linux Policy for the xm processes
7
9 Security-Enhanced Linux secures the xm processes via flexible mandatory
10 access control.
11 The xm processes execute with the xm_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15 For example:
17 ps -eZ | grep xm_t
19
23 The xm_t SELinux type can be entered via the xm_exec_t file type.
24 The default entrypoint paths for the xm_t domain are the following:
26 /usr/sbin/xm, /usr/bin/virsh
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux xm
36 policy is very flexible allowing users to setup their xm processes in
37 as secure a method as possible.
38 The following process types are defined for xm:
40 xm_t, xm_ssh_t
42 Note: semanage permissive -a xm_t can be used to make the process type
44 xm_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
49 SELinux policy is customizable based on least access required. xm pol‐
50 icy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run xm with the tightest access possible.
52 If you want to allow all daemons the ability to read/write terminals,
56 you must turn on the allow_daemons_use_tty boolean. Disabled by
57 default.
58 setsebool -P allow_daemons_use_tty 1
60 If you want to allow all domains to use other domains file descriptors,
64 you must turn on the allow_domain_fd_use boolean. Enabled by default.
65 setsebool -P allow_domain_fd_use 1
67 If you want to allow sysadm to debug or ptrace all processes, you must
71 turn on the allow_ptrace boolean. Disabled by default.
72 setsebool -P allow_ptrace 1
74 If you want to allow all domains to have the kernel load modules, you
78 must turn on the domain_kernel_load_modules boolean. Disabled by
79 default.
80 setsebool -P domain_kernel_load_modules 1
82 If you want to allow all domains to execute in fips_mode, you must turn
86 on the fips_mode boolean. Enabled by default.
87 setsebool -P fips_mode 1
89 If you want to enable reading of urandom for all domains, you must turn
93 on the global_ssp boolean. Disabled by default.
94 setsebool -P global_ssp 1
96 If you want to allow virt to manage nfs files, you must turn on the
100 virt_use_nfs boolean. Disabled by default.
101 setsebool -P virt_use_nfs 1
103 If you want to allow virt to manage cifs files, you must turn on the
107 virt_use_samba boolean. Disabled by default.
108 setsebool -P virt_use_samba 1
110
114 The SELinux process type xm_t can manage files labeled with the follow‐
115 ing file types. The paths listed are the default paths for these file
116 types. Note the processes UID still need to have DAC permissions.

195 SELinux requires files to have an extended attribute to define the file
196 type.
197 You can see the context of a file using the -Z option to ls
199 Policy governs the access confined processes have to these files.
201 SELinux xm policy is very flexible allowing users to setup their xm
202 processes in as secure a method as possible.
203 The following file types are defined for xm:
205 xm_exec_t
209 - Set files with the xm_exec_t type, if you want to transition an exe‐
211 cutable to the xm_t domain.
212 Paths:
215 /usr/sbin/xm, /usr/bin/virsh
216 Note: File context can be temporarily modified with the chcon command.
219 If you want to permanently change the file context you need to use the
220 semanage fcontext command. This will modify the SELinux labeling data‐
221 base. You will need to use restorecon to apply the labels.
222
225 semanage fcontext can also be used to manipulate default file context
226 mappings.
227 semanage permissive can also be used to manipulate whether or not a
229 process type is permissive.
230 semanage module can also be used to enable/disable/install/remove pol‐
232 icy modules.
233 semanage boolean can also be used to manipulate the booleans
235 system-config-selinux is a GUI tool available to customize SELinux pol‐
238 icy settings.
