NAME

6       iotop_selinux - Security Enhanced Linux Policy for the iotop processes
7

DESCRIPTION

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

21

ENTRYPOINTS

23       The iotop_t SELinux type can be entered via the iotop_exec_t file type.
24
25       The default entrypoint paths for the iotop_t domain are the following:
26
27       /usr/sbin/iotop
28

PROCESS TYPES

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

48

BOOLEANS

50       SELinux policy is customizable based on least access  required.   iotop
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run iotop with the tightest access possible.
53
54
55
56       If you want to allow users to resolve user passwd entries directly from
57       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
58       gin_nsswitch_use_ldap boolean. Disabled by default.
59
60       setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64       If you want to deny any process from ptracing or  debugging  any  other
65       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
66       default.
67
68       setsebool -P deny_ptrace 1
69
70
71
72       If you want to allow any process  to  mmap  any  file  on  system  with
73       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
74       ean. Enabled by default.
75
76       setsebool -P domain_can_mmap_files 1
77
78
79
80       If you want to allow all domains write to kmsg_device, while kernel  is
81       executed  with  systemd.log_target=kmsg parameter, you must turn on the
82       domain_can_write_kmsg boolean. Disabled by default.
83
84       setsebool -P domain_can_write_kmsg 1
85
86
87
88       If you want to allow all domains to use other domains file descriptors,
89       you must turn on the domain_fd_use boolean. Enabled by default.
90
91       setsebool -P domain_fd_use 1
92
93
94
95       If  you  want to allow all domains to have the kernel load modules, you
96       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
97       default.
98
99       setsebool -P domain_kernel_load_modules 1
100
101
102
103       If you want to allow all domains to execute in fips_mode, you must turn
104       on the fips_mode boolean. Enabled by default.
105
106       setsebool -P fips_mode 1
107
108
109
110       If you want to enable reading of urandom for all domains, you must turn
111       on the global_ssp boolean. Disabled by default.
112
113       setsebool -P global_ssp 1
114
115
116
117       If  you  want  to allow confined applications to run with kerberos, you
118       must turn on the kerberos_enabled boolean. Enabled by default.
119
120       setsebool -P kerberos_enabled 1
121
122
123
124       If you want to allow system to run with  NIS,  you  must  turn  on  the
125       nis_enabled boolean. Disabled by default.
126
127       setsebool -P nis_enabled 1
128
129
130
131       If  you  want to allow confined applications to use nscd shared memory,
132       you must turn on the nscd_use_shm boolean. Disabled by default.
133
134       setsebool -P nscd_use_shm 1
135
136
137

FILE CONTEXTS

139       SELinux requires files to have an extended attribute to define the file
140       type.
141
142       You can see the context of a file using the -Z option to ls
143
144       Policy  governs  the  access  confined  processes  have to these files.
145       SELinux iotop policy is very flexible allowing  users  to  setup  their
146       iotop processes in as secure a method as possible.
147
148       The following file types are defined for iotop:
149
150
151
152       iotop_exec_t
153
154       -  Set  files  with the iotop_exec_t type, if you want to transition an
155       executable to the iotop_t domain.
156
157
158
159       Note: File context can be temporarily modified with the chcon  command.
160       If  you want to permanently change the file context you need to use the
161       semanage fcontext command.  This will modify the SELinux labeling data‐
162       base.  You will need to use restorecon to apply the labels.
163
164

COMMANDS

166       semanage  fcontext  can also be used to manipulate default file context
167       mappings.
168
169       semanage permissive can also be used to manipulate  whether  or  not  a
170       process type is permissive.
171
172       semanage  module can also be used to enable/disable/install/remove pol‐
173       icy modules.
174
175       semanage boolean can also be used to manipulate the booleans
176
177
178       system-config-selinux is a GUI tool available to customize SELinux pol‐
179       icy settings.
