Description of problem: SELinux policy does not allow syslogd to write to named pipes. How reproducible: Everytime Steps to Reproduce: 1. Create named pipe in /var/log/ (eg. mkfifo /var/log/msgpipe) 2. Edit syslog.conf to use the pipe (eg. *.notice;authpriv.none |/var/log/msgpipe) 3. start syslogd Actual results: kernel: audit(): avc: denied { read write } for pid=xxx comm="syslogd" name="msgpipe" dev=xxx ino=xxx scontext=user_u:system_r:syslogd_t:s0 tcontext=user_u:object_r:var_log_t:s0 tclass=fifo_file Expected results: syslogd starts with no avc: denied messages. Additional info: Enable fifo in policy (policy/modules/system/logging.te) by adding: allow syslogd_t var_t:fifo_file { ioctl read write };
