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.
71 anon_inodefs_t
73 cifs_t
76 data_home_t
79 /root/.local/share(/.*)?
81 /home/[^/]+/.local/share(/.*)?
82 dovecot_spool_t
84 /var/spool/dovecot(/.*)?
86 ecryptfs_t
88 /home/[^/]+/.Private(/.*)?
90 /home/[^/]+/.ecryptfs(/.*)?
91 fusefs_t
93 /var/run/user/[^/]*/gvfs
95 mail_home_rw_t
97 /root/Maildir(/.*)?
99 /root/.esmtp_queue(/.*)?
100 /var/lib/arpwatch/.esmtp_queue(/.*)?
101 /home/[^/]+/.maildir(/.*)?
102 /home/[^/]+/Maildir(/.*)?
103 /home/[^/]+/.esmtp_queue(/.*)?
104 nfs_t
106 user_home_t
109 /home/[^/]+/.+

114 SELinux requires files to have an extended attribute to define the file
115 type.
116 You can see the context of a file using the -Z option to ls
118 Policy governs the access confined processes have to these files.
120 SELinux procmail policy is very flexible allowing users to setup their
121 procmail processes in as secure a method as possible.
122 EQUIVALENCE DIRECTORIES
124 procmail policy stores data with multiple different file context types
127 under the /var/log/procmail directory. If you would like to store the
128 data in a different directory you can use the semanage command to cre‐
129 ate an equivalence mapping. If you wanted to store this data under the
130 /srv directory you would execute the following command:
131 semanage fcontext -a -e /var/log/procmail /srv/procmail
133 restorecon -R -v /srv/procmail
134 STANDARD FILE CONTEXT
136 SELinux defines the file context types for the procmail, if you wanted
138 to store files with these types in a diffent paths, you need to execute
139 the semanage command to sepecify alternate labeling and then use
140 restorecon to put the labels on disk.
141 semanage fcontext -a -t procmail_tmp_t '/srv/myprocmail_content(/.*)?'
143 restorecon -R -v /srv/myprocmail_content
144 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147 The following file types are defined for procmail:
149 procmail_exec_t
153 - Set files with the procmail_exec_t type, if you want to transition an
155 executable to the procmail_t domain.
156 procmail_home_t
160 - Set files with the procmail_home_t type, if you want to store proc‐
162 mail files in the users home directory.
163 Paths:
166 /root/.procmailrc, /home/[^/]+/.procmailrc
167 procmail_log_t
170 - Set files with the procmail_log_t type, if you want to treat the data
172 as procmail log data, usually stored under the /var/log directory.
173 Paths:
176 /var/log/procmail(/.*)?, /var/log/procmail.log.*
177 procmail_tmp_t
180 - Set files with the procmail_tmp_t type, if you want to store procmail
182 temporary files in the /tmp directories.
183 Note: File context can be temporarily modified with the chcon command.
187 If you want to permanently change the file context you need to use the
188 semanage fcontext command. This will modify the SELinux labeling data‐
189 base. You will need to use restorecon to apply the labels.
190
193 semanage fcontext can also be used to manipulate default file context
194 mappings.
195 semanage permissive can also be used to manipulate whether or not a
197 process type is permissive.
198 semanage module can also be used to enable/disable/install/remove pol‐
200 icy modules.
201 semanage boolean can also be used to manipulate the booleans
203 system-config-selinux is a GUI tool available to customize SELinux pol‐
206 icy settings.
