We don't have quota support for NFS in the policy. I guess we should just allow it to write to all non XAttr file systems. Fixed in selinux-policy-3.7.19-142.el6 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: When running xfstest (test 230) on ext4 partition test fails because selinux denies writing to this partition. Partition is mounted with these options: '-o context=system_u:object_r:nfs_t:s0 -o grpquota,usrquota'. After mounting the partition /sbin/quotacheck is started but it outputs Permission denied for writing to mounted partition. When selinux is turned off everything runs as it should. Version-Release number of selected component (if applicable): Quota utilities version 3.17. Steps to Reproduce: 1. create ext4 partition 2. mount it with '-o context=system_u:object_r:nfs_t:s0 -o grpquota,usrquota' 3. run '/sbin/quotacheck -g -u -m /partition/mountpoint' (fails here) (following steps were not tested) 4. run '/sbin/quotaon /partition/mountpoint' 5. run '/usr/sbin/setquota -u user 1000 2000 3 5 /partition/mountpoint' 6. run '/usr/sbin/setquota -g user 1000 2000 3 5 /partition/mountpoint' Actual results: step 3 prits out: quotacheck: Cannot create new quotafile /partition/mountpoint/aquota.user.new: Permission denied quotacheck: Cannot initialize IO on new quotafile: Permission denied quotacheck: Cannot create new quotafile /partition/mountpoint/aquota.group.new: Permission denied quotacheck: Cannot initialize IO on new quotafile: Permission denied output in /var/log/audit/audit.log: type=AVC msg=audit(1330758684.492:658): avc: denied { write } for pid=10360 comm="quotacheck" name="/" dev=dm-1 ino=2 scontext=unconfined_u:unconfined_r:quota_t:s0-s0:c0.c1023 tcontext=system_u:object_r:nfs_t:s0 tclass=dir type=SYSCALL msg=audit(1330758684.492:658): arch=c000003e syscall=2 success=no exit=-13 a0=7fffee502160 a1=c2 a2=180 a3=7fffee501eb0 items=0 ppid=10173 pid=10360 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=1 comm="quotacheck" exe="/sbin/quotacheck" subj=unconfined_u:unconfined_r:quota_t:s0-s0:c0.c1023 key=(null) type=AVC msg=audit(1330758684.492:659): avc: denied { write } for pid=10360 comm="quotacheck" name="/" dev=dm-1 ino=2 scontext=unconfined_u:unconfined_r:quota_t:s0-s0:c0.c1023 tcontext=system_u:object_r:nfs_t:s0 tclass=dir type=SYSCALL msg=audit(1330758684.492:659): arch=c000003e syscall=2 success=no exit=-13 a0=7fffee502160 a1=c2 a2=180 a3=7fffee502180 items=0 ppid=10173 pid=10360 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts0 ses=1 comm="quotacheck" exe="/sbin/quotacheck" subj=unconfined_u:unconfined_r:quota_t:s0-s0:c0.c1023 key=(null) Expected results: step 3 should create two files in /parrtition/mountpoint - aquota.group and aquota.user steps 4,5,6 should then write into these files
