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 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 control the ability to mmap a low area of the address
70       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
71       the mmap_low_allowed boolean. Disabled by default.
72
73       setsebool -P mmap_low_allowed 1
74
75
76
77       If  you  want  to  disable  kernel module loading, you must turn on the
78       secure_mode_insmod boolean. Enabled by default.
79
80       setsebool -P secure_mode_insmod 1
81
82
83
84       If you want to allow unconfined executables to make their  heap  memory
85       executable.   Doing  this  is  a  really bad idea. Probably indicates a
86       badly coded executable, but could indicate an attack.  This  executable
87       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
88       uxuser_execheap boolean. Disabled by default.
89
90       setsebool -P selinuxuser_execheap 1
91
92
93
94       If you want to allow unconfined executables to make  their  stack  exe‐
95       cutable.   This  should  never, ever be necessary. Probably indicates a
96       badly coded executable, but could indicate an attack.  This  executable
97       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
98       stack boolean. Disabled by default.
99
100       setsebool -P selinuxuser_execstack 1

MANAGED FILES

105       The SELinux process type sosreport_t can manage files labeled with  the
106       following file types.  The paths listed are the default paths for these
107       file types.  Note the processes UID still need to have DAC permissions.
108
109       file_type
110
111            all files on the system
112
113

FILE CONTEXTS

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy  governs  the  access  confined  processes  have to these files.
121       SELinux sosreport policy is very flexible allowing users to setup their
122       sosreport processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux defines the file context types for the sosreport, if you wanted
127       to store files with these types in a diffent paths, you need to execute
128       the  semanage  command  to  sepecify  alternate  labeling  and then use
129       restorecon to put the labels on disk.
130
131       semanage  fcontext  -a  -t  sosreport_var_run_t  '/srv/mysosreport_con‐
132       tent(/.*)?'
133       restorecon -R -v /srv/mysosreport_content
134
135       Note:  SELinux  often  uses  regular expressions to specify labels that
136       match multiple files.
137
138       The following file types are defined for sosreport:
139
140
141
142       sosreport_exec_t
143
144       - Set files with the sosreport_exec_t type, if you want  to  transition
145       an executable to the sosreport_t domain.
146
147
148
149       sosreport_tmp_t
150
151       -  Set files with the sosreport_tmp_t type, if you want to store sosre‐
152       port temporary files in the /tmp directories.
153
154
155
156       sosreport_tmpfs_t
157
158       - Set files with the sosreport_tmpfs_t type, if you want to store  sos‐
159       report files on a tmpfs file system.
160
161
162
163       sosreport_var_run_t
164
165       - Set files with the sosreport_var_run_t type, if you want to store the
166       sosreport files under the /run or /var/run directory.
167
168
169
170       Note: File context can be temporarily modified with the chcon  command.
171       If  you want to permanently change the file context you need to use the
172       semanage fcontext command.  This will modify the SELinux labeling data‐
173       base.  You will need to use restorecon to apply the labels.
174
175

COMMANDS

177       semanage  fcontext  can also be used to manipulate default file context
178       mappings.
179
180       semanage permissive can also be used to manipulate  whether  or  not  a
181       process type is permissive.
182
183       semanage  module can also be used to enable/disable/install/remove pol‐
184       icy modules.
185
186       semanage boolean can also be used to manipulate the booleans
187
188
189       system-config-selinux is a GUI tool available to customize SELinux pol‐
190       icy settings.
