NAME

6       procmail_selinux - Security Enhanced Linux Policy for the procmail pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  procmail  processes  via  flexible
11       mandatory access control.
12
13       The  procmail  processes  execute with the procmail_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 procmail_t
20
21
22

ENTRYPOINTS

24       The procmail_t SELinux type can be entered via the procmail_exec_t file
25       type.
26
27       The default entrypoint paths for the procmail_t domain are the  follow‐
28       ing:
29
30       /usr/bin/procmail
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       procmail policy is very flexible allowing users to setup their procmail
40       processes in as secure a method as possible.
41
42       The following process types are defined for procmail:
43
44       procmail_t
45
46       Note: semanage permissive -a procmail_t can be used to make the process
47       type  procmail_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.  proc‐
54       mail policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run procmail with the tightest access
56       possible.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you  want  to allow confined applications to run with kerberos, you
68       must turn on the allow_kerberos boolean. Enabled by default.
69
70       setsebool -P allow_kerberos 1
71
72
73
74       If you want to allow sysadm to debug or ptrace all processes, you  must
75       turn on the allow_ptrace boolean. Disabled by default.
76
77       setsebool -P allow_ptrace 1
78
79
80
81       If  you  want  to  allow  system  to run with NIS, you must turn on the
82       allow_ypbind boolean. Disabled by default.
83
84       setsebool -P allow_ypbind 1
85
86
87
88       If you want to allow all domains to have the kernel load  modules,  you
89       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
90       default.
91
92       setsebool -P domain_kernel_load_modules 1
93
94
95
96       If you want to allow all domains to execute in fips_mode, you must turn
97       on the fips_mode boolean. Enabled by default.
98
99       setsebool -P fips_mode 1
100
101
102
103       If you want to enable reading of urandom for all domains, you must turn
104       on the global_ssp boolean. Disabled by default.
105
106       setsebool -P global_ssp 1
107
108
109
110       If you want to allow confined applications to use nscd  shared  memory,
111       you must turn on the nscd_use_shm boolean. Enabled by default.
112
113       setsebool -P nscd_use_shm 1
114
115
116
117       If  you  want  to  support  NFS  home directories, you must turn on the
118       use_nfs_home_dirs boolean. Disabled by default.
119
120       setsebool -P use_nfs_home_dirs 1
121
122
123
124       If you want to support SAMBA home directories, you  must  turn  on  the
125       use_samba_home_dirs boolean. Disabled by default.
126
127       setsebool -P use_samba_home_dirs 1

MANAGED FILES

132       The  SELinux  process type procmail_t can manage files labeled with the
133       following file types.  The paths listed are the default paths for these
134       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

198       SELinux requires files to have an extended attribute to define the file
199       type.
200
201       You can see the context of a file using the -Z option to ls
202
203       Policy governs the access  confined  processes  have  to  these  files.
204       SELinux  procmail policy is very flexible allowing users to setup their
205       procmail processes in as secure a method as possible.
206
207       EQUIVALENCE DIRECTORIES
208
209
210       procmail policy stores data with multiple different file context  types
211       under  the /var/log/procmail directory.  If you would like to store the
212       data in a different directory you can use the semanage command to  cre‐
213       ate an equivalence mapping.  If you wanted to store this data under the
214       /srv dirctory you would execute the following command:
215
216       semanage fcontext -a -e /var/log/procmail /srv/procmail
217       restorecon -R -v /srv/procmail
218
219       STANDARD FILE CONTEXT
220
221       SELinux defines the file context types for the procmail, if you  wanted
222       to store files with these types in a diffent paths, you need to execute
223       the semanage command  to  sepecify  alternate  labeling  and  then  use
224       restorecon to put the labels on disk.
225
226       semanage fcontext -a -t procmail_tmp_t '/srv/myprocmail_content(/.*)?'
227       restorecon -R -v /srv/myprocmail_content
228
229       Note:  SELinux  often  uses  regular expressions to specify labels that
230       match multiple files.
231
232       The following file types are defined for procmail:
233
234
235
236       procmail_exec_t
237
238       - Set files with the procmail_exec_t type, if you want to transition an
239       executable to the procmail_t domain.
240
241
242
243       procmail_home_t
244
245       -  Set  files with the procmail_home_t type, if you want to store proc‐
246       mail files in the users home directory.
247
248
249       Paths:
250            /root/.procmailrc,   /home/[^/]*/.procmailrc,   /home/staff/.proc‐
251            mailrc
252
253
254       procmail_log_t
255
256       - Set files with the procmail_log_t type, if you want to treat the data
257       as procmail log data, usually stored under the /var/log directory.
258
259
260       Paths:
261            /var/log/procmail(/.*)?, /var/log/procmail.log.*
262
263
264       procmail_tmp_t
265
266       - Set files with the procmail_tmp_t type, if you want to store procmail
267       temporary files in the /tmp directories.
268
269
270
271       Note:  File context can be temporarily modified with the chcon command.
272       If you want to permanently change the file context you need to use  the
273       semanage fcontext command.  This will modify the SELinux labeling data‐
274       base.  You will need to use restorecon to apply the labels.
275
276

COMMANDS

278       semanage fcontext can also be used to manipulate default  file  context
279       mappings.
280
281       semanage  permissive  can  also  be used to manipulate whether or not a
282       process type is permissive.
283
284       semanage module can also be used to enable/disable/install/remove  pol‐
285       icy modules.
286
287       semanage boolean can also be used to manipulate the booleans
288
289
290       system-config-selinux is a GUI tool available to customize SELinux pol‐
291       icy settings.
