NAME

6       samba_unconfined_net_selinux  -  Security Enhanced Linux Policy for the
7       samba_unconfined_net processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the samba_unconfined_net processes  via
11       flexible mandatory access control.
12
13       The   samba_unconfined_net  processes  execute  with  the  samba_uncon‐
14       fined_net_t SELinux type. You can check if  you  have  these  processes
15       running by executing the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep samba_unconfined_net_t
20

22

ENTRYPOINTS

24       The   samba_unconfined_net_t  SELinux  type  can  be  entered  via  the
25       samba_net_exec_t file type.
26
27       The default entrypoint paths for the samba_unconfined_net_t domain  are
28       the following:
29
30       /usr/bin/net
31

PROCESS TYPES

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       samba_unconfined_net  policy  is  very flexible allowing users to setup
40       their samba_unconfined_net processes in as secure a method as possible.
41
42       The following process types are defined for samba_unconfined_net:
43
44       samba_unconfined_net_t
45
46       Note: semanage permissive -a samba_unconfined_net_t can be used to make
47       the  process  type  samba_unconfined_net_t permissive. SELinux does not
48       deny access to permissive process types, but the AVC (SELinux  denials)
49       messages are still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       samba_unconfined_net policy is extremely flexible and has several bool‐
55       eans  that  allow  you  to  manipulate  the policy and run samba_uncon‐
56       fined_net with the tightest access possible.
57
58
59
60       If you want to deny user domains applications to map a memory region as
61       both  executable  and  writable,  this  is dangerous and the executable
62       should be reported in bugzilla, you must turn on the deny_execmem bool‐
63       ean. Enabled by default.
64
65       setsebool -P deny_execmem 1
66
67
68
69       If  you  want  to deny any process from ptracing or debugging any other
70       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
71       default.
72
73       setsebool -P deny_ptrace 1
74
75
76
77       If  you  want  to  allow  any  process  to mmap any file on system with
78       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
79       ean. Enabled by default.
80
81       setsebool -P domain_can_mmap_files 1
82
83
84
85       If  you want to allow all domains write to kmsg_device, while kernel is
86       executed with systemd.log_target=kmsg parameter, you must turn  on  the
87       domain_can_write_kmsg boolean. Disabled by default.
88
89       setsebool -P domain_can_write_kmsg 1
90
91
92
93       If you want to allow all domains to use other domains file descriptors,
94       you must turn on the domain_fd_use boolean. Enabled by default.
95
96       setsebool -P domain_fd_use 1
97
98
99
100       If you want to allow all domains to have the kernel load  modules,  you
101       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
102       default.
103
104       setsebool -P domain_kernel_load_modules 1
105
106
107
108       If you want to allow all domains to execute in fips_mode, you must turn
109       on the fips_mode boolean. Enabled by default.
110
111       setsebool -P fips_mode 1
112
113
114
115       If you want to enable reading of urandom for all domains, you must turn
116       on the global_ssp boolean. Disabled by default.
117
118       setsebool -P global_ssp 1
119
120
121
122       If you want to control the ability to mmap a low area  of  the  address
123       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
124       the mmap_low_allowed boolean. Disabled by default.
125
126       setsebool -P mmap_low_allowed 1
127
128
129
130       If you want to disable kernel module loading,  you  must  turn  on  the
131       secure_mode_insmod boolean. Enabled by default.
132
133       setsebool -P secure_mode_insmod 1
134
135
136
137       If  you want to boolean to determine whether the system permits loading
138       policy, setting enforcing mode, and changing boolean values.  Set  this
139       to  true  and  you  have to reboot to set it back, you must turn on the
140       secure_mode_policyload boolean. Enabled by default.
141
142       setsebool -P secure_mode_policyload 1
143
144
145
146       If you want to allow unconfined executables to make their  heap  memory
147       executable.   Doing  this  is  a  really bad idea. Probably indicates a
148       badly coded executable, but could indicate an attack.  This  executable
149       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
150       uxuser_execheap boolean. Disabled by default.
151
152       setsebool -P selinuxuser_execheap 1
153
154
155
156       If you want to  allow  all  unconfined  executables  to  use  libraries
157       requiring  text  relocation  that  are not labeled textrel_shlib_t, you
158       must turn on the selinuxuser_execmod boolean. Enabled by default.
159
160       setsebool -P selinuxuser_execmod 1
161
162
163
164       If you want to allow unconfined executables to make  their  stack  exe‐
165       cutable.   This  should  never, ever be necessary. Probably indicates a
166       badly coded executable, but could indicate an attack.  This  executable
167       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
168       stack boolean. Enabled by default.
169
170       setsebool -P selinuxuser_execstack 1
171
172
173
174       If you want to support X userspace object manager, you must turn on the
175       xserver_object_manager boolean. Enabled by default.
176
177       setsebool -P xserver_object_manager 1
178

MANAGED FILES

182       The  SELinux  process  type  samba_unconfined_net_t  can  manage  files
183       labeled with the following  file  types.   The  paths  listed  are  the
184       default  paths for these file types.  Note the processes UID still need
185       to have DAC permissions.
186
187       file_type
188
189            all files on the system
190
191

COMMANDS

193       semanage fcontext can also be used to manipulate default  file  context
194       mappings.
195
196       semanage  permissive  can  also  be used to manipulate whether or not a
197       process type is permissive.
198
199       semanage module can also be used to enable/disable/install/remove  pol‐
200       icy modules.
201
202       semanage boolean can also be used to manipulate the booleans
203
204
205       system-config-selinux is a GUI tool available to customize SELinux pol‐
206       icy settings.
