Also, how do I get it to be able to write to the nfs directory?
type=AVC msg=audit(1354230531.020:131120): avc: denied { write } for pid=6958 comm="rsync" name="METEORS" dev=0:1c ino=251527171 scontext=system_u:system_r:rsync_t:s0-s0:c0.c1023 tcontext=system_u:object_r:nfs_t:s0 tclass=dir
allow_rsync_anon_write --> on
rsync_client --> off
rsync_export_all_ro --> off
rsync_use_cifs --> off
rsync_use_nfs --> on
I tried turning on allow_rsync_anon_write but that didn't help.
Eventually needed to add exceptions for:
module rsync-server 1.0;
require {
type autofs_t;
type rsync_t;
type nfs_t;
class file create;
class dir { write search add_name };
}
#============= rsync_t ==============
#!!!! This avc can be allowed using the boolean 'rsync_export_all_ro'
allow rsync_t autofs_t:dir search;
#!!!! This avc is allowed in the current policy
allow rsync_t nfs_t:dir { write search add_name };
#!!!! This avc is allowed in the current policy
allow rsync_t nfs_t:file create;
I made rsync as userdom_home_manager to fix these issues. Will backport. (In reply to comment #4) > I made rsync as userdom_home_manager to fix these issues. I meant in Fedora. I eventually had to disable dontaudit rules to be able to see:
type=AVC msg=audit(1354294154.636:548): avc: denied { write } for pid=14828 comm="rsync" name=".blah.cp9LNd" dev=0:21 ino=580976863 scontext=system_u:system_r:rsync_t:s0-s0:c0.c1023 tcontext=system_u:object_r:nfs_t:s0 tclass=file
module rsync-server 1.0;
require {
type autofs_t;
type rsync_t;
type nfs_t;
class file { write rename create unlink setattr };
class dir { write search setattr remove_name create add_name };
}
#============= rsync_t ==============
#!!!! This avc is allowed in the current policy
allow rsync_t autofs_t:dir search;
#!!!! This avc is allowed in the current policy
allow rsync_t nfs_t:dir { write search setattr remove_name create add_name };
allow rsync_t nfs_t:file write;
#!!!! This avc is allowed in the current policy
allow rsync_t nfs_t:file { rename create unlink setattr };
Yes, it will be covered by new rules. Looks good to me. Thanks! Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
