6 procmail_selinux - Security Enhanced Linux Policy for the procmail pro‐
7 cesses
8
10 Security-Enhanced Linux secures the procmail processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep procmail_t
20
24 The procmail_t SELinux type can be entered via the procmail_exec_t file
25 type.
26 The default entrypoint paths for the procmail_t domain are the follow‐
28 ing:
29 /usr/bin/procmail
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for procmail:
43 procmail_t
45 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
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 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type procmail_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux procmail policy is very flexible allowing users to setup their
143 procmail processes in as secure a method as possible.
144 EQUIVALENCE DIRECTORIES
146 procmail policy stores data with multiple different file context types
149 under the /var/log/procmail directory. If you would like to store the
150 data in a different directory you can use the semanage command to cre‐
151 ate an equivalence mapping. If you wanted to store this data under the
152 /srv directory you would execute the following command:
153 semanage fcontext -a -e /var/log/procmail /srv/procmail
155 restorecon -R -v /srv/procmail
156 STANDARD FILE CONTEXT
158 SELinux defines the file context types for the procmail, if you wanted
160 to store files with these types in a different paths, you need to exe‐
161 cute the semanage command to specify alternate labeling and then use
162 restorecon to put the labels on disk.
163 semanage fcontext -a -t procmail_exec_t '/srv/procmail/content(/.*)?'
165 restorecon -R -v /srv/myprocmail_content
166 Note: SELinux often uses regular expressions to specify labels that
168 match multiple files.
169 The following file types are defined for procmail:
171 procmail_exec_t
175 - Set files with the procmail_exec_t type, if you want to transition an
177 executable to the procmail_t domain.
178 procmail_home_t
182 - Set files with the procmail_home_t type, if you want to store proc‐
184 mail files in the users home directory.
185 Paths:
188 /root/.procmailrc, /home/[^/]+/.procmailrc
189 procmail_log_t
192 - Set files with the procmail_log_t type, if you want to treat the data
194 as procmail log data, usually stored under the /var/log directory.
195 Paths:
198 /var/log/procmail(/.*)?, /var/log/procmail.log.*
199 procmail_tmp_t
202 - Set files with the procmail_tmp_t type, if you want to store procmail
204 temporary files in the /tmp directories.
205 Note: File context can be temporarily modified with the chcon command.
209 If you want to permanently change the file context you need to use the
210 semanage fcontext command. This will modify the SELinux labeling data‐
211 base. You will need to use restorecon to apply the labels.
212
215 semanage fcontext can also be used to manipulate default file context
216 mappings.
217 semanage permissive can also be used to manipulate whether or not a
219 process type is permissive.
220 semanage module can also be used to enable/disable/install/remove pol‐
222 icy modules.
223 semanage boolean can also be used to manipulate the booleans
225 system-config-selinux is a GUI tool available to customize SELinux pol‐
228 icy settings.
