NAME

6       sosreport_selinux  -  Security  Enhanced Linux Policy for the sosreport
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the sosreport  processes  via  flexible
11       mandatory access control.
12
13       The  sosreport processes execute with the sosreport_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep sosreport_t
20
21
22

ENTRYPOINTS

24       The  sosreport_t  SELinux  type can be entered via the sosreport_exec_t
25       file type.
26
27       The default entrypoint paths for the sosreport_t domain are the follow‐
28       ing:
29
30       /usr/sbin/sosreport
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       sosreport  policy is very flexible allowing users to setup their sosre‐
40       port processes in as secure a method as possible.
41
42       The following process types are defined for sosreport:
43
44       sosreport_t
45
46       Note: semanage permissive -a  sosreport_t  can  be  used  to  make  the
47       process  type  sosreport_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy is customizable based on least access required.  sosre‐
54       port policy is extremely flexible and has several booleans  that  allow
55       you to manipulate the policy and run sosreport with the tightest access
56       possible.
57
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to deny user domains applications to map a memory region as
69       both  executable  and  writable,  this  is dangerous and the executable
70       should be reported in bugzilla, you must turn on the deny_execmem bool‐
71       ean. Enabled by default.
72
73       setsebool -P deny_execmem 1
74
75
76
77       If you want to allow all domains to execute in fips_mode, you must turn
78       on the fips_mode boolean. Enabled by default.
79
80       setsebool -P fips_mode 1
81
82
83
84       If you want to allow confined applications to run  with  kerberos,  you
85       must turn on the kerberos_enabled boolean. Disabled by default.
86
87       setsebool -P kerberos_enabled 1
88
89
90
91       If  you  want  to control the ability to mmap a low area of the address
92       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
93       the mmap_low_allowed boolean. Disabled by default.
94
95       setsebool -P mmap_low_allowed 1
96
97
98
99       If  you  want  to  allow  system  to run with NIS, you must turn on the
100       nis_enabled boolean. Disabled by default.
101
102       setsebool -P nis_enabled 1
103
104
105
106       If you want to allow confined applications to use nscd  shared  memory,
107       you must turn on the nscd_use_shm boolean. Disabled by default.
108
109       setsebool -P nscd_use_shm 1
110
111
112
113       If  you  want  to  disable  kernel module loading, you must turn on the
114       secure_mode_insmod boolean. Enabled by default.
115
116       setsebool -P secure_mode_insmod 1
117
118
119
120       If you want to allow unconfined executables to make their  heap  memory
121       executable.   Doing  this  is  a  really bad idea. Probably indicates a
122       badly coded executable, but could indicate an attack.  This  executable
123       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
124       uxuser_execheap boolean. Disabled by default.
125
126       setsebool -P selinuxuser_execheap 1
127
128
129
130       If you want to allow unconfined executables to make  their  stack  exe‐
131       cutable.   This  should  never, ever be necessary. Probably indicates a
132       badly coded executable, but could indicate an attack.  This  executable
133       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
134       stack boolean. Disabled by default.
135
136       setsebool -P selinuxuser_execstack 1

MANAGED FILES

141       The SELinux process type sosreport_t can manage files labeled with  the
142       following file types.  The paths listed are the default paths for these
143       file types.  Note the processes UID still need to have DAC permissions.
144
145       file_type
146
147            all files on the system
148
149

FILE CONTEXTS

151       SELinux requires files to have an extended attribute to define the file
152       type.
153
154       You can see the context of a file using the -Z option to ls
155
156       Policy  governs  the  access  confined  processes  have to these files.
157       SELinux sosreport policy is very flexible allowing users to setup their
158       sosreport processes in as secure a method as possible.
159
160       STANDARD FILE CONTEXT
161
162       SELinux defines the file context types for the sosreport, if you wanted
163       to store files with these types in a diffent paths, you need to execute
164       the  semanage  command  to  sepecify  alternate  labeling  and then use
165       restorecon to put the labels on disk.
166
167       semanage  fcontext  -a  -t  sosreport_var_run_t  '/srv/mysosreport_con‐
168       tent(/.*)?'
169       restorecon -R -v /srv/mysosreport_content
170
171       Note:  SELinux  often  uses  regular expressions to specify labels that
172       match multiple files.
173
174       The following file types are defined for sosreport:
175
176
177
178       sosreport_exec_t
179
180       - Set files with the sosreport_exec_t type, if you want  to  transition
181       an executable to the sosreport_t domain.
182
183
184
185       sosreport_tmp_t
186
187       -  Set files with the sosreport_tmp_t type, if you want to store sosre‐
188       port temporary files in the /tmp directories.
189
190
191
192       sosreport_tmpfs_t
193
194       - Set files with the sosreport_tmpfs_t type, if you want to store  sos‐
195       report files on a tmpfs file system.
196
197
198
199       sosreport_var_run_t
200
201       - Set files with the sosreport_var_run_t type, if you want to store the
202       sosreport files under the /run or /var/run directory.
203
204
205
206       Note: File context can be temporarily modified with the chcon  command.
207       If  you want to permanently change the file context you need to use the
208       semanage fcontext command.  This will modify the SELinux labeling data‐
209       base.  You will need to use restorecon to apply the labels.
210
211

COMMANDS

213       semanage  fcontext  can also be used to manipulate default file context
214       mappings.
215
216       semanage permissive can also be used to manipulate  whether  or  not  a
217       process type is permissive.
218
219       semanage  module can also be used to enable/disable/install/remove pol‐
220       icy modules.
221
222       semanage boolean can also be used to manipulate the booleans
223
224
225       system-config-selinux is a GUI tool available to customize SELinux pol‐
226       icy settings.
