NAME

6       abrt_handle_event_selinux  -  Security  Enhanced  Linux  Policy for the
7       abrt_handle_event processes
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  abrt_handle_event  processes  via
11       flexible mandatory access control.
12
13       The  abrt_handle_event  processes  execute with the abrt_handle_event_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 abrt_handle_event_t
20
21
22

ENTRYPOINTS

24       The  abrt_handle_event_t  SELinux type can be entered via the abrt_han‐
25       dle_event_exec_t file type.
26
27       The default entrypoint paths for the abrt_handle_event_t domain are the
28       following:
29
30       /usr/libexec/abrt-handle-event
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       abrt_handle_event policy is very flexible allowing users to setup their
40       abrt_handle_event processes in as secure a method as possible.
41
42       The following process types are defined for abrt_handle_event:
43
44       abrt_handle_event_t
45
46       Note: semanage permissive -a abrt_handle_event_t can be  used  to  make
47       the  process type abrt_handle_event_t permissive. SELinux does not deny
48       access to permissive process types, but the AVC (SELinux denials)  mes‐
49       sages are still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       abrt_handle_event policy is extremely flexible and has several booleans
55       that  allow you to manipulate the policy and run abrt_handle_event with
56       the tightest access possible.
57
58
59
60       If you want  to  determine  whether  ABRT  can  run  in  the  abrt_han‐
61       dle_event_t  domain  to handle ABRT event scripts, you must turn on the
62       abrt_handle_event boolean. Disabled by default.
63
64       setsebool -P abrt_handle_event 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 deny any process from ptracing or debugging any other
78       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
79       default.
80
81       setsebool -P deny_ptrace 1
82
83
84
85       If  you  want  to  allow  any  process  to mmap any file on system with
86       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
87       ean. Enabled by default.
88
89       setsebool -P domain_can_mmap_files 1
90
91
92
93       If  you want to allow all domains write to kmsg_device, while kernel is
94       executed with systemd.log_target=kmsg parameter, you must turn  on  the
95       domain_can_write_kmsg boolean. Disabled by default.
96
97       setsebool -P domain_can_write_kmsg 1
98
99
100
101       If you want to allow all domains to use other domains file descriptors,
102       you must turn on the domain_fd_use boolean. Enabled by default.
103
104       setsebool -P domain_fd_use 1
105
106
107
108       If you want to allow all domains to have the kernel load  modules,  you
109       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
110       default.
111
112       setsebool -P domain_kernel_load_modules 1
113
114
115
116       If you want to allow all domains to execute in fips_mode, you must turn
117       on the fips_mode boolean. Enabled by default.
118
119       setsebool -P fips_mode 1
120
121
122
123       If you want to enable reading of urandom for all domains, you must turn
124       on the global_ssp boolean. Disabled by default.
125
126       setsebool -P global_ssp 1
127
128
129
130       If you want to control the ability to mmap a low area  of  the  address
131       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
132       the mmap_low_allowed boolean. Disabled by default.
133
134       setsebool -P mmap_low_allowed 1
135
136
137
138       If you want to disable kernel module loading,  you  must  turn  on  the
139       secure_mode_insmod boolean. Enabled by default.
140
141       setsebool -P secure_mode_insmod 1
142
143
144
145       If  you want to boolean to determine whether the system permits loading
146       policy, setting enforcing mode, and changing boolean values.  Set  this
147       to  true  and  you  have to reboot to set it back, you must turn on the
148       secure_mode_policyload boolean. Enabled by default.
149
150       setsebool -P secure_mode_policyload 1
151
152
153
154       If you want to allow unconfined executables to make their  heap  memory
155       executable.   Doing  this  is  a  really bad idea. Probably indicates a
156       badly coded executable, but could indicate an attack.  This  executable
157       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
158       uxuser_execheap boolean. Disabled by default.
159
160       setsebool -P selinuxuser_execheap 1
161
162
163
164       If you want to  allow  all  unconfined  executables  to  use  libraries
165       requiring  text  relocation  that  are not labeled textrel_shlib_t, you
166       must turn on the selinuxuser_execmod boolean. Enabled by default.
167
168       setsebool -P selinuxuser_execmod 1
169
170
171
172       If you want to allow unconfined executables to make  their  stack  exe‐
173       cutable.   This  should  never, ever be necessary. Probably indicates a
174       badly coded executable, but could indicate an attack.  This  executable
175       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
176       stack boolean. Enabled by default.
177
178       setsebool -P selinuxuser_execstack 1
179
180
181
182       If you want to support X userspace object manager, you must turn on the
183       xserver_object_manager boolean. Enabled by default.
184
185       setsebool -P xserver_object_manager 1
186

MANAGED FILES

190       The  SELinux  process type abrt_handle_event_t can manage files labeled
191       with the following file types.  The paths listed are the default  paths
192       for  these  file  types.  Note the processes UID still need to have DAC
193       permissions.
194
195       file_type
196
197            all files on the system
198
199

FILE CONTEXTS

201       SELinux requires files to have an extended attribute to define the file
202       type.
203
204       You can see the context of a file using the -Z option to ls
205
206       Policy  governs  the  access  confined  processes  have to these files.
207       SELinux abrt_handle_event policy is very  flexible  allowing  users  to
208       setup their abrt_handle_event processes in as secure a method as possi‐
209       ble.
210
211       The following file types are defined for abrt_handle_event:
212
213
214
215       abrt_handle_event_exec_t
216
217       - Set files with the abrt_handle_event_exec_t  type,  if  you  want  to
218       transition an executable to the abrt_handle_event_t domain.
219
220
221
222       Note:  File context can be temporarily modified with the chcon command.
223       If you want to permanently change the file context you need to use  the
224       semanage fcontext command.  This will modify the SELinux labeling data‐
225       base.  You will need to use restorecon to apply the labels.
226
227

COMMANDS

229       semanage fcontext can also be used to manipulate default  file  context
230       mappings.
231
232       semanage  permissive  can  also  be used to manipulate whether or not a
233       process type is permissive.
234
235       semanage module can also be used to enable/disable/install/remove  pol‐
236       icy modules.
237
238       semanage boolean can also be used to manipulate the booleans
239
240
241       system-config-selinux is a GUI tool available to customize SELinux pol‐
242       icy settings.
