6 unconfined_mono_selinux - Security Enhanced Linux Policy for the uncon‐
7 fined_mono processes
8
10 Security-Enhanced Linux secures the unconfined_mono processes via flex‐
11 ible mandatory access control.
12 The unconfined_mono processes execute with the unconfined_mono_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep unconfined_mono_t
20
24 The unconfined_mono_t SELinux type can be entered via the file_type,
25 unlabeled_t, proc_type, filesystem_type, mtrr_device_t, mono_exec_t,
26 sysctl_type, xsession_exec_t file types.
27 The default entrypoint paths for the unconfined_mono_t domain are the
29 following:
30 all files on the system, /dev/cpu/mtrr, /usr/bin/mono.*,
32 /etc/kde3?/kdm/Xreset, /etc/kde3?/kdm/Xstartup, /etc/kde3?/kdm/Xses‐
33 sion, /etc/X11/[wx]dm/Xreset.*, /etc/X11/[wxg]dm/Xsession,
34 /etc/X11/Xsession[^/]*, /etc/X11/wdm/Xsetup.*, /etc/X11/wdm/Xstartup.*

37 SELinux defines process types (domains) for each process running on the
38 system
39 You can see the context of a process using the -Z option to ps
41 Policy governs the access confined processes have to files. SELinux
43 unconfined_mono policy is very flexible allowing users to setup their
44 unconfined_mono processes in as secure a method as possible.
45 The following process types are defined for unconfined_mono:
47 unconfined_mono_t
49 Note: semanage permissive -a unconfined_mono_t can be used to make the
51 process type unconfined_mono_t permissive. SELinux does not deny access
52 to permissive process types, but the AVC (SELinux denials) messages are
53 still generated.
54
57 SELinux policy is customizable based on least access required. uncon‐
58 fined_mono policy is extremely flexible and has several booleans that
59 allow you to manipulate the policy and run unconfined_mono with the
60 tightest access possible.
61 If you want to allow direct login to the console device. Required for
65 System 390, you must turn on the allow_console_login boolean. Enabled
66 by default.

76 If you want to allow unconfined executables to make their heap memory
80 executable. Doing this is a really bad idea. Probably indicates a

82 should be reported in bugzilla, you must turn on the allow_execheap
83 boolean. Disabled by default.
84 setsebool -P allow_execheap 1
86 If you want to allow unconfined executables to map a memory region as
90 both executable and writable, this is dangerous and the executable
91 should be reported in bugzilla), you must turn on the allow_execmem
92 boolean. Enabled by default.
93 setsebool -P allow_execmem 1
95 If you want to allow all unconfined executables to use libraries
99 requiring text relocation that are not labeled textrel_shlib_t), you
100 must turn on the allow_execmod boolean. Enabled by default.
101 setsebool -P allow_execmod 1
103 If you want to allow unconfined executables to make their stack exe‐
107 cutable. This should never, ever be necessary. Probably indicates a
108 badly coded executable, but could indicate an attack. This executable
109 should be reported in bugzilla), you must turn on the allow_execstack
110 boolean. Enabled by default.
111 setsebool -P allow_execstack 1

117 must turn on the allow_kerberos boolean. Enabled by default.
118 setsebool -P allow_kerberos 1
120 If you want to allow sysadm to debug or ptrace all processes, you must
124 turn on the allow_ptrace boolean. Disabled by default.
125 setsebool -P allow_ptrace 1
127 If you want to transition to confined nsplugin domains from unconfined
131 user, you must turn on the allow_unconfined_nsplugin_transition bool‐
132 ean. Disabled by default.
133 setsebool -P allow_unconfined_nsplugin_transition 1
135 If you want to allows clients to write to the X server shared memory
139 segments, you must turn on the allow_write_xshm boolean. Disabled by
140 default.
141 setsebool -P allow_write_xshm 1
143 If you want to allow system to run with NIS, you must turn on the
147 allow_ypbind boolean. Disabled by default.
148 setsebool -P allow_ypbind 1
150 If you want to allow all domains to have the kernel load modules, you
154 must turn on the domain_kernel_load_modules boolean. Disabled by
155 default.
156 setsebool -P domain_kernel_load_modules 1
158 If you want to allow all domains to execute in fips_mode, you must turn
162 on the fips_mode boolean. Enabled by default.
163 setsebool -P fips_mode 1
165 If you want to enable reading of urandom for all domains, you must turn
169 on the global_ssp boolean. Disabled by default.
170 setsebool -P global_ssp 1
172 If you want to allow certain domains to map low memory in the kernel,
176 you must turn on the mmap_low_allowed boolean. Disabled by default.
177 setsebool -P mmap_low_allowed 1
179 If you want to allow confined applications to use nscd shared memory,
183 you must turn on the nscd_use_shm boolean. Enabled by default.
184 setsebool -P nscd_use_shm 1
186 If you want to enabling secure mode disallows programs, such as new‐
190 role, from transitioning to administrative user domains, you must turn
191 on the secure_mode boolean. Disabled by default.
192 setsebool -P secure_mode 1
194 If you want to boolean to determine whether the system permits loading
198 policy, setting enforcing mode, and changing boolean values. Set this

243 The SELinux process type unconfined_mono_t can manage files labeled
244 with the following file types. The paths listed are the default paths
245 for these file types. Note the processes UID still need to have DAC
246 permissions.
247 file_type
249 all files on the system
251
254 semanage fcontext can also be used to manipulate default file context
255 mappings.
256 semanage permissive can also be used to manipulate whether or not a
258 process type is permissive.
259 semanage module can also be used to enable/disable/install/remove pol‐
261 icy modules.
262 semanage boolean can also be used to manipulate the booleans
264 system-config-selinux is a GUI tool available to customize SELinux pol‐
267 icy settings.
