| Summary | 0017600: Dovecot SELinux policy insufficient | ||||
| Description | The SELinux policy for dovecot seems insufficient for SELinux to be left enforcing out of the box when using dovecot with at least MySQL and a home directory provided via SQL in the user_query. It may be a broader issue, but I have not tested in a more default state. I am following the same setup I run on CentOS 7 where it works. The symptom is that dovecot will complain in its logs that it cannot chdir, Jul 17 18:44:02 msa01 dovecot[141453]: imap(test@example.com)<142355><IQy65KqqreBMCcF0>: Error: chdir(/mailmount//example.com/test/) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) stat() failed: No such file or directory) | ||||
| Steps To Reproduce | Leave SELinux enforcing Setup dovecot to use the mysql driver and provide home via SQL query Set mail_location = maildir:~/Maildir in 10-mail.conf | ||||
| Additional Information | The `dontaudit` settings hide anything from appearing in the audit.log. Disabling those and setting SELinux permissive shows the following, #============= dovecot_auth_t ============== # src="dovecot_auth_t" tgt="init_t" class="unix_stream_socket", perms="{ read write }" # comm="auth" exe="" path="" #!!!!
