NAME

6       ftpdctl_selinux  -  Security Enhanced Linux Policy for the ftpdctl pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  ftpdctl  processes  via  flexible
11       mandatory access control.
12
13       The  ftpdctl processes execute with the ftpdctl_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 ftpdctl_t
20
21
22

ENTRYPOINTS

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

BOOLEANS

53       SELinux policy is customizable based on least access required.  ftpdctl
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run ftpdctl with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow all daemons the ability to  read/write  terminals,
61       you must turn on the daemons_use_tty boolean. Disabled by default.
62
63       setsebool -P daemons_use_tty 1
64
65
66
67       If  you  want  to deny any process from ptracing or debugging any other
68       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
69       default.
70
71       setsebool -P deny_ptrace 1
72
73
74
75       If  you  want  to  allow  any  process  to mmap any file on system with
76       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
77       ean. Enabled by default.
78
79       setsebool -P domain_can_mmap_files 1
80
81
82
83       If  you want to allow all domains write to kmsg_device, while kernel is
84       executed with systemd.log_target=kmsg parameter, you must turn  on  the
85       domain_can_write_kmsg boolean. Disabled by default.
86
87       setsebool -P domain_can_write_kmsg 1
88
89
90
91       If you want to allow all domains to use other domains file descriptors,
92       you must turn on the domain_fd_use boolean. Enabled by default.
93
94       setsebool -P domain_fd_use 1
95
96
97
98       If you want to allow all domains to have the kernel load  modules,  you
99       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
100       default.
101
102       setsebool -P domain_kernel_load_modules 1
103
104
105
106       If you want to allow all domains to execute in fips_mode, you must turn
107       on the fips_mode boolean. Enabled by default.
108
109       setsebool -P fips_mode 1
110
111
112
113       If you want to enable reading of urandom for all domains, you must turn
114       on the global_ssp boolean. Disabled by default.
115
116       setsebool -P global_ssp 1

FILE CONTEXTS

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

COMMANDS

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