7 cesses

10 Security-Enhanced Linux secures the qemu_dm processes via flexible
11 mandatory access control.
12
13 The qemu_dm processes execute with the qemu_dm_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep qemu_dm_t
20
21
22
24 The qemu_dm_t SELinux type can be entered via the qemu_dm_exec_t file
25 type.
26
27 The default entrypoint paths for the qemu_dm_t domain are the follow‐
28 ing:

31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 qemu_dm policy is very flexible allowing users to setup their qemu_dm
40 processes in as secure a method as possible.
41
42 The following process types are defined for qemu_dm:
43
44 qemu_dm_t
45
46 Note: semanage permissive -a qemu_dm_t can be used to make the process
47 type qemu_dm_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. qemu_dm
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run qemu_dm with the tightest access possi‐
56 ble.

59
60 If you want to deny any process from ptracing or debugging any other
61 processes, you must turn on the deny_ptrace boolean. Enabled by
62 default.
63
64 setsebool -P deny_ptrace 1
65
66
67
68 If you want to allow any process to mmap any file on system with
69 attribute file_type, you must turn on the domain_can_mmap_files bool‐
70 ean. Enabled by default.
71
72 setsebool -P domain_can_mmap_files 1
73
74
75
76 If you want to allow all domains write to kmsg_device, while kernel is
77 executed with systemd.log_target=kmsg parameter, you must turn on the
78 domain_can_write_kmsg boolean. Disabled by default.
79
80 setsebool -P domain_can_write_kmsg 1
81
82
83
84 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the domain_fd_use boolean. Enabled by default.
86
87 setsebool -P domain_fd_use 1
88
89
90
91 If you want to allow all domains to have the kernel load modules, you
92 must turn on the domain_kernel_load_modules boolean. Disabled by
93 default.
94
95 setsebool -P domain_kernel_load_modules 1
96
97
98
99 If you want to allow all domains to execute in fips_mode, you must turn
100 on the fips_mode boolean. Enabled by default.
101
102 setsebool -P fips_mode 1
103
104
105
106 If you want to enable reading of urandom for all domains, you must turn
107 on the global_ssp boolean. Disabled by default.
108
109 setsebool -P global_ssp 1
110
111
112
113 If you want to allow xend to run qemu-dm. Not required if using par‐
114 avirt and no vfb, you must turn on the xend_run_qemu boolean. Enabled
115 by default.
116
117 setsebool -P xend_run_qemu 1
118
119
120
122 The SELinux process type qemu_dm_t can manage files labeled with the
123 following file types. The paths listed are the default paths for these
124 file types. Note the processes UID still need to have DAC permissions.

131 semanage fcontext can also be used to manipulate default file context
132 mappings.
133
134 semanage permissive can also be used to manipulate whether or not a
135 process type is permissive.
136
137 semanage module can also be used to enable/disable/install/remove pol‐
138 icy modules.
139
140 semanage boolean can also be used to manipulate the booleans
141

143 system-config-selinux is a GUI tool available to customize SELinux pol‐
144 icy settings.
