NAME

6       unconfined_cronjob_selinux  -  Security  Enhanced  Linux Policy for the
7       unconfined_cronjob processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the  unconfined_cronjob  processes  via
11       flexible mandatory access control.
12
13       The  unconfined_cronjob processes execute with the unconfined_cronjob_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_cronjob_t

PROCESS TYPES

24       SELinux defines process types (domains) for each process running on the
25       system
26
27       You can see the context of a process using the -Z option to ps
28
29       Policy governs the access confined processes have  to  files.   SELinux
30       unconfined_cronjob  policy  is  very  flexible  allowing users to setup
31       their unconfined_cronjob processes in as secure a method as possible.
32
33       The following process types are defined for unconfined_cronjob:
34
35       unconfined_cronjob_t
36
37       Note: semanage permissive -a unconfined_cronjob_t can be used  to  make
38       the process type unconfined_cronjob_t permissive. SELinux does not deny
39       access to permissive process types, but the AVC (SELinux denials)  mes‐
40       sages are still generated.
41
42

BOOLEANS

44       SELinux  policy is customizable based on least access required.  uncon‐
45       fined_cronjob policy is extremely flexible  and  has  several  booleans
46       that allow you to manipulate the policy and run unconfined_cronjob with
47       the tightest access possible.
48
49
50
51       If you want to deny user domains applications to map a memory region as
52       both  executable  and  writable,  this  is dangerous and the executable
53       should be reported in bugzilla, you must turn on the deny_execmem bool‐
54       ean. Enabled by default.
55
56       setsebool -P deny_execmem 1
57
58
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 control the ability to mmap a low area  of  the  address
114       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
115       the mmap_low_allowed boolean. Disabled by default.
116
117       setsebool -P mmap_low_allowed 1
118
119
120
121       If you want to disable kernel module loading,  you  must  turn  on  the
122       secure_mode_insmod boolean. Enabled by default.
123
124       setsebool -P secure_mode_insmod 1
125
126
127
128       If  you want to boolean to determine whether the system permits loading
129       policy, setting enforcing mode, and changing boolean values.  Set  this
130       to  true  and  you  have to reboot to set it back, you must turn on the
131       secure_mode_policyload boolean. Enabled by default.
132
133       setsebool -P secure_mode_policyload 1
134
135
136
137       If you want to allow unconfined executables to make their  heap  memory
138       executable.   Doing  this  is  a  really bad idea. Probably indicates a
139       badly coded executable, but could indicate an attack.  This  executable
140       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
141       uxuser_execheap boolean. Disabled by default.
142
143       setsebool -P selinuxuser_execheap 1
144
145
146
147       If you want to  allow  all  unconfined  executables  to  use  libraries
148       requiring  text  relocation  that  are not labeled textrel_shlib_t, you
149       must turn on the selinuxuser_execmod boolean. Enabled by default.
150
151       setsebool -P selinuxuser_execmod 1
152
153
154
155       If you want to allow unconfined executables to make  their  stack  exe‐
156       cutable.   This  should  never, ever be necessary. Probably indicates a
157       badly coded executable, but could indicate an attack.  This  executable
158       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
159       stack boolean. Enabled by default.
160
161       setsebool -P selinuxuser_execstack 1
162
163
164
165       If you want to support X userspace object manager, you must turn on the
166       xserver_object_manager boolean. Enabled by default.
167
168       setsebool -P xserver_object_manager 1
169

MANAGED FILES

173       The  SELinux process type unconfined_cronjob_t can manage files labeled
174       with the following file types.  The paths listed are the default  paths
175       for  these  file  types.  Note the processes UID still need to have DAC
176       permissions.
177
178       file_type
179
180            all files on the system
181
182

COMMANDS

184       semanage fcontext can also be used to manipulate default  file  context
185       mappings.
186
187       semanage  permissive  can  also  be used to manipulate whether or not a
188       process type is permissive.
189
190       semanage module can also be used to enable/disable/install/remove  pol‐
191       icy modules.
192
193       semanage boolean can also be used to manipulate the booleans
194
195
196       system-config-selinux is a GUI tool available to customize SELinux pol‐
197       icy settings.
