Description Keiichi Mori 2001-03-13 06:55:31 EST 
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [muriyari-ja] (X11; U; Linux 2.2.16-22 i686)


When Windows9x client access to SAMBA server, it cannot create files over
size limited by quota.
It is normal behavior.
But when Windows2000 client access to, it can create files over size
limited by quota.
(Windows2000 shows a Warning message.)



Reproducible: Always
Steps to Reproduce:
1.create quota file system. (/etc/fstab: /dev/hda5 /home usrquota,....)
2.Edit quota with edquota command. 
3.Edit smb.config so as to access the partition limited by quota.)
4.Windows 2000 client access to SAMBA server, and create( copy, ...) big
file (over limited size).


Actual Results:  Windows2000 shows Warning message. But it has created file
over limited size.


Expected Results:  SAMBA don not let Windows2000 client to create file over
limit size.
Comment 1 Keiichi Mori 2001-03-29 04:58:27 EST 
I make a patch for this problem.
I'm sure that the problem has been resolved by applying this patch.

Would you try to test this patch?
If you approve this patch, would you apply this patch to samba RPM package?

Comment 2 Bill Nottingham 2001-03-29 17:16:45 EST 
*** Bug 33915 has been marked as a duplicate of this bug. ***
Comment 3 Bill Nottingham 2001-03-29 17:17:43 EST 
This patch is completely broken; it does not build in a 7.0 environment.

Does this problem only occur when running on a 2.4.recent kernel?
Comment 4 Keiichi Mori 2001-03-29 23:13:28 EST 
This problem occur when running on both 2.2 kernel and a 2.4.recent kernel

But I'm sorry. I have mixed the patch for this problem and the patch only for
kernel2.4.
So I break up the patch what I sent to you into two patches.

"samba-quotafix.patch" is a patch for resolving this problems.
I build this on RH7.0 environment and on RH7.1 QA0327 environment.

"samba-quota4kernel24.patch" is a patch for samba running on kernel 2.4.
I build this only on RH7.1 QA0327 environment.

Comment 5 Bill Nottingham 2001-03-30 00:17:10 EST 
OK, both parts are applied in 2.0.7-35; the first patch may make its
way into a 7.0 samba package.
Comment 6 Keiichi Mori 2001-04-01 20:39:52 EDT 
Thank you very much.
If you release sampa-2.0.7-35 package, I'd like to test this and report.
