NAME

6       depmod_selinux  -  Security  Enhanced  Linux Policy for the depmod pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  depmod_t  SELinux  type  can be entered via the depmod_exec_t file
25       type.
26
27       The default entrypoint paths for the depmod_t domain are the following:
28
29       /sbin/depmod.*, /usr/sbin/depmod.*
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       depmod policy is very flexible allowing users  to  setup  their  depmod
39       processes in as secure a method as possible.
40
41       The following process types are defined for depmod:
42
43       depmod_t
44
45       Note:  semanage  permissive -a depmod_t can be used to make the process
46       type depmod_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least access required.   depmod
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run depmod with the tightest access possible.
55
56
57
58       If you want to deny user domains applications to map a memory region as
59       both  executable  and  writable,  this  is dangerous and the executable
60       should be reported in bugzilla, you must turn on the deny_execmem bool‐
61       ean. Enabled by default.
62
63       setsebool -P deny_execmem 1
64
65
66
67       If you want to allow all domains to execute in fips_mode, you must turn
68       on the fips_mode boolean. Enabled by default.
69
70       setsebool -P fips_mode 1
71
72
73
74       If you want to control the ability to mmap a low area  of  the  address
75       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
76       the mmap_low_allowed boolean. Disabled by default.
77
78       setsebool -P mmap_low_allowed 1
79
80
81
82       If you want to disable kernel module loading,  you  must  turn  on  the
83       secure_mode_insmod boolean. Enabled by default.
84
85       setsebool -P secure_mode_insmod 1
86
87
88
89       If  you  want to allow unconfined executables to make their heap memory
90       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
91       badly  coded  executable, but could indicate an attack. This executable
92       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
93       uxuser_execheap boolean. Disabled by default.
94
95       setsebool -P selinuxuser_execheap 1
96
97
98
99       If  you  want  to allow unconfined executables to make their stack exe‐
100       cutable.  This should never, ever be necessary.  Probably  indicates  a
101       badly  coded  executable, but could indicate an attack. This executable
102       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
103       stack boolean. Enabled by default.
104
105       setsebool -P selinuxuser_execstack 1

MANAGED FILES

110       The  SELinux  process  type  depmod_t can manage files labeled with the
111       following file types.  The paths listed are the default paths for these
112       file types.  Note the processes UID still need to have DAC permissions.
113
114       file_type
115
116            all files on the system
117
118

FILE CONTEXTS

120       SELinux requires files to have an extended attribute to define the file
121       type.
122
123       You can see the context of a file using the -Z option to ls
124
125       Policy governs the access  confined  processes  have  to  these  files.
126       SELinux  depmod  policy  is very flexible allowing users to setup their
127       depmod processes in as secure a method as possible.
128
129       The following file types are defined for depmod:
130
131
132
133       depmod_exec_t
134
135       - Set files with the depmod_exec_t type, if you want to  transition  an
136       executable to the depmod_t domain.
137
138
139       Paths:
140            /sbin/depmod.*, /usr/sbin/depmod.*
141
142
143       Note:  File context can be temporarily modified with the chcon command.
144       If you want to permanently change the file context you need to use  the
145       semanage fcontext command.  This will modify the SELinux labeling data‐
146       base.  You will need to use restorecon to apply the labels.
147
148

COMMANDS

150       semanage fcontext can also be used to manipulate default  file  context
151       mappings.
152
153       semanage  permissive  can  also  be used to manipulate whether or not a
154       process type is permissive.
155
156       semanage module can also be used to enable/disable/install/remove  pol‐
157       icy modules.
158
159       semanage boolean can also be used to manipulate the booleans
160
161
162       system-config-selinux is a GUI tool available to customize SELinux pol‐
163       icy settings.
