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

128 SELinux requires files to have an extended attribute to define the file
129 type.
130 You can see the context of a file using the -Z option to ls
132 Policy governs the access confined processes have to these files.
134 SELinux procmail policy is very flexible allowing users to setup their
135 procmail processes in as secure a method as possible.
136 EQUIVALENCE DIRECTORIES
138 procmail policy stores data with multiple different file context types
141 under the /var/log/procmail directory. If you would like to store the
142 data in a different directory you can use the semanage command to cre‐
143 ate an equivalence mapping. If you wanted to store this data under the
144 /srv directory you would execute the following command:
145 semanage fcontext -a -e /var/log/procmail /srv/procmail
147 restorecon -R -v /srv/procmail
148 STANDARD FILE CONTEXT
150 SELinux defines the file context types for the procmail, if you wanted
152 to store files with these types in a diffent paths, you need to execute
153 the semanage command to specify alternate labeling and then use re‐
154 storecon to put the labels on disk.
155 semanage fcontext -a -t procmail_tmp_t '/srv/myprocmail_content(/.*)?'
157 restorecon -R -v /srv/myprocmail_content
158 Note: SELinux often uses regular expressions to specify labels that
160 match multiple files.
161 The following file types are defined for procmail:
163 procmail_exec_t
167 - Set files with the procmail_exec_t type, if you want to transition an
169 executable to the procmail_t domain.
170 procmail_home_t
174 - Set files with the procmail_home_t type, if you want to store proc‐
176 mail files in the users home directory.
177 Paths:
180 /root/.procmailrc, /home/[^/]+/.procmailrc
181 procmail_log_t
184 - Set files with the procmail_log_t type, if you want to treat the data
186 as procmail log data, usually stored under the /var/log directory.
187 Paths:
190 /var/log/procmail(/.*)?, /var/log/procmail.log.*
191 procmail_tmp_t
194 - Set files with the procmail_tmp_t type, if you want to store procmail
196 temporary files in the /tmp directories.
197 Note: File context can be temporarily modified with the chcon command.
201 If you want to permanently change the file context you need to use the
202 semanage fcontext command. This will modify the SELinux labeling data‐
203 base. You will need to use restorecon to apply the labels.
204
207 semanage fcontext can also be used to manipulate default file context
208 mappings.
209 semanage permissive can also be used to manipulate whether or not a
211 process type is permissive.
212 semanage module can also be used to enable/disable/install/remove pol‐
214 icy modules.
215 semanage boolean can also be used to manipulate the booleans
217 system-config-selinux is a GUI tool available to customize SELinux pol‐
220 icy settings.
