Description of problem: clamsmtpd in its default configuration (/etc/clamd.d/clamsmtp.conf) uses /var/lib/clamd.clamsmtp as the data directory. This directory is labeled by default with var_lib_t type, and SELinux prevents clamd to write its temporary data there. Version-Release number of selected component (if applicable): clamsmtp-1.10-1.fc14.x86_64 clamav-0.96.5-1400.fc14.x86_64 clamav-server-0.96.5-1400.fc14.x86_64 postfix-2.7.1-1.fc14.x86_64 selinux-policy-targeted-3.9.7-20.fc14.noarch How reproducible: 100 % Steps to Reproduce: 1. Install F14 with the above packages, and without sendmail. 2. Configure postfix to use clamav/clamsmtpd - for example using this howto: http://www.debian-administration.org/articles/259 3. label the port 10026 as smtp_port_t using the following command: semanage port -a -t smtp_port_t -p tcp 10026 4. start postfix, clamav, clamsmtpd 5. telnet localhost 10025, and send a test e-mail using SMTP Actual results: internal server error with the following line in /var/log/maillog: clamav error: /var/lib/clamd.clamsmtp/clamsmtpd.SgR8xa: lstat() failed: Permission denied. ERROR Expected results: The verified e-mail should be passed back to postfix. Additional info: Labeling the files the following way fixes the problem: semanage fcontext -a -t clamd_var_lib_t /var/lib/clamd.clamsmtp/'(.*)' semanage fcontext -a -t clamd_var_lib_t /var/lib/clamd.clamsmtp I think the above two settings should be added to the default policy for clamd. The label of port 10026 (smtp_port_t) can be also added to the policy.
Looks like we need a policy update for this. @dwalsh, the package installs the directory as part of the spec. The ports 10025 and 10026 are user configurable but the config file uses those by default, so I'm not sure if they should be labeled or not.
clamsmtp needs selinux-policy. Currently is runs unprotected so we should write policy for it.
Miroslav lets add /var/lib/clamd.* gen_context(system_u:object_r:clamd_var_lib_t,s0) for now to F13 and F14 10025 is labeled network_port(amavisd_send, tcp,10025,s0)
10025 is OK, but 10026 should probably be labeled smtp_port_t. At least this is what worked for me.
Just assigning to Dan Williams who is likely more able to handle this.
This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
