NAME

6       unconfined_notrans_selinux  -  Security  Enhanced  Linux Policy for the
7       unconfined_notrans processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the  unconfined_notrans  processes  via
11       flexible mandatory access control.
12
13       The  unconfined_notrans processes execute with the unconfined_notrans_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
17       For example:
18
19       ps -eZ | grep unconfined_notrans_t
20
21
22

ENTRYPOINTS

24       The unconfined_notrans_t SELinux type can be entered via the file_type,
25       unlabeled_t,  proc_type,  unconfined_notrans_exec_t,   filesystem_type,
26       mtrr_device_t, sysctl_type file types.
27
28       The  default  entrypoint  paths for the unconfined_notrans_t domain are
29       the following:
30
31       all  files  on   the   system,   /usr/sbin/mock,   /usr/sbin/sysreport,
32       /dev/cpu/mtrr
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       unconfined_notrans  policy  is  very  flexible  allowing users to setup
42       their unconfined_notrans processes in as secure a method as possible.
43
44       The following process types are defined for unconfined_notrans:
45
46       unconfined_notrans_t
47
48       Note: semanage permissive -a unconfined_notrans_t can be used  to  make
49       the process type unconfined_notrans_t permissive. SELinux does not deny
50       access to permissive process types, but the AVC (SELinux denials)  mes‐
51       sages are still generated.
52
53

BOOLEANS

55       SELinux  policy is customizable based on least access required.  uncon‐
56       fined_notrans policy is extremely flexible  and  has  several  booleans
57       that allow you to manipulate the policy and run unconfined_notrans with
58       the tightest access possible.
59
60
61
62       If you want to allow direct login to the console device.  Required  for
63       System  390,  you must turn on the allow_console_login boolean. Enabled
64       by default.

66       setsebool -P allow_console_login 1
67
68
69

82
83
84
85       If  you  want to allow unconfined executables to make their heap memory
86       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
87       badly  coded  executable, but could indicate an attack. This executable
88       should be reported in bugzilla, you must  turn  on  the  allow_execheap
89       boolean. Disabled by default.
90
91       setsebool -P allow_execheap 1
92
93
94
95       If  you  want to allow unconfined executables to map a memory region as
96       both executable and writable, this  is  dangerous  and  the  executable
97       should  be  reported  in  bugzilla), you must turn on the allow_execmem
98       boolean. Enabled by default.

109
110
111
112       If you want to allow unconfined executables to make  their  stack  exe‐
113       cutable.   This  should  never, ever be necessary. Probably indicates a
114       badly coded executable, but could indicate an attack.  This  executable
115       should  be  reported in bugzilla), you must turn on the allow_execstack
116       boolean. Enabled by default.
117
118       setsebool -P allow_execstack 1
119
120

MANAGED FILES

234       The  SELinux process type unconfined_notrans_t can manage files labeled
235       with the following file types.  The paths listed are the default  paths
236       for  these  file  types.  Note the processes UID still need to have DAC
237       permissions.
238
239       file_type
240
241            all files on the system
242
243

FILE CONTEXTS

245       SELinux requires files to have an extended attribute to define the file
246       type.
247
248       You can see the context of a file using the -Z option to ls
249
250       Policy  governs  the  access  confined  processes  have to these files.
251       SELinux unconfined_notrans policy is very flexible  allowing  users  to
252       setup  their unconfined_notrans processes in as secure a method as pos‐
253       sible.
254
255       The following file types are defined for unconfined_notrans:
256
257
258
259       unconfined_notrans_exec_t
260
261       - Set files with the unconfined_notrans_exec_t type,  if  you  want  to
262       transition an executable to the unconfined_notrans_t domain.
263
264
265       Paths:
266            /usr/sbin/mock, /usr/sbin/sysreport
267
268
269       Note:  File context can be temporarily modified with the chcon command.
270       If you want to permanently change the file context you need to use  the
271       semanage fcontext command.  This will modify the SELinux labeling data‐
272       base.  You will need to use restorecon to apply the labels.
273
274

COMMANDS

276       semanage fcontext can also be used to manipulate default  file  context
277       mappings.
278
279       semanage  permissive  can  also  be used to manipulate whether or not a
280       process type is permissive.
281
282       semanage module can also be used to enable/disable/install/remove  pol‐
283       icy modules.
284
285       semanage boolean can also be used to manipulate the booleans
286
287
288       system-config-selinux is a GUI tool available to customize SELinux pol‐
289       icy settings.
