Description jcpunk 2012-12-28 18:37:24 UTC
Description of problem: I would like to configure rsyncd to log directly to a specific file (/var/log/rsyncd.log).  The default selinux policy seems to let me create the logfile, but not append to it.


audit.log:type=AVC msg=audit(1356671905.822:1360202): avc:  denied  { append } for  pid=22174 comm="rsync" name="rsyncd.log" dev=sda6 ino=46 scontext=unconfined_u:system_r:rsync_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_log_t:s0 tclass=file
audit.log:type=AVC msg=audit(1356671906.132:1360203): avc:  denied  { append } for  pid=22177 comm="rsync" name="rsyncd.log" dev=sda6 ino=46 scontext=unconfined_u:system_r:rsync_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_log_t:s0 tclass=file



Version-Release number of selected component (if applicable): selinux-policy-3.7.19-155.el6_3.8


How reproducible: 100%


Steps to Reproduce:
1. set 'log file = /var/log/rsyncd.log' in /etc/rsyncd.conf
2. chkconfig rsync on
3. chkconfig xinetd on
4. do something worth logging
5. stop xinetd
6. start xinetd
7. do something worth logging
8. note new actions are not in the log
  
Actual results:
stops using log

Expected results:
continues to use log

Additional info:

rsyncd falls back to syslog when it cannot open the log file

Comment 2 Miroslav Grepl 2012-12-30 21:51:20 UTC
We allow it in Fedora

allow daemon logfile : file { ioctl getattr lock append } ;

You can allow it for now using

# grep rsync_t /var/log/audit/audit.log |audit2allow -R -M myrsync
# semodule -i myrsync.pp
