Description Chris Rogers 2009-07-23 14:30:31 UTC

When the system boots, all filesystems listed in /etc/fstab are expected to mount with all options listed.  However, when one filesystem has both quota and noexec options, the noexec option is ignored, while quotas work.  If the quota option is removed, noexec will work.

Line in /etc/fstab:
/dev/md4 /home ext3 noatime,nosuid,noexec,usrjquota=aquota.user,jqfmt=vfsv0 0 0

Output of mount:
/dev/md4 on /home type ext3 (rw,noexec,nosuid,noatime,usrjquota=aquota.user,jqfmt=vfsv0)

Output of /proc/mounts:
/dev/md4 /home ext3 rw,errors=continue,data=ordered,jqfmt=vfsv0,usrjquota=aquota.user 0 0

If I run 'mount -o remount /home', then the output of /proc/mounts becomes:
/dev/md4 /home ext3 rw,nosuid,noexec,noatime,errors=continue,data=ordered,jqfmt=vfsv0,usrjquota=aquota.user 0 0

Once I remount the filesystem by hand, everything works as it should.  I am having the same results with both of the following kernels:
-gentoo-sources-2.6.29-r5
-hardened-sources-2.6.28-r9

During initial setup I used the following stage3 tarball:
stage3-amd64-hardened-2008.0

Reproducible: Always

Steps to Reproduce:
1.  Copy /bin/echo to /home
2.  run '/home/echo a'


Actual Results:  
'a' is echoed to the console

Expected Results:  
bash: /home/echo: Permission denied
