On what kernel are you testing this?

Comment 2 Tru Huynh 2009-01-28 21:58:44 UTC
2.6.18-92.1.22.el5 with cifs version 1.50cRH

Comment 3 Jeff Layton 2009-01-28 22:08:04 UTC
Could you test this with a 5.3 kernel (-128.el5 or later)?

If that doesn't work, then please try the test kernels on my people.redhat.com page:

    http://people.redhat.com/jlayton

...they have CIFS patches that I'm testing for 5.4. There are some plaintext auth fixes in there so it's possible that this is already fixed.

Comment 4 Tru Huynh 2009-01-28 22:50:47 UTC
According to Akemi (see CentOS entry) and by reading the cifs folder, the bug is still there on the GA of RHEL-5.3 (-128 release). I am attaching the 2 lines patch, maybe it's faster if you could check it against your src.rpm? otherwise I can download your src.rpm and glance at them.

Thanks

Tru

upstream patched from samba bugzilla

Comment 6 Tru Huynh 2009-01-28 22:58:11 UTC
ok I see the 2 patches which are fixing the issue:
465143	019-bz-465143-cifs-fix-plaintext-a.patch
465143	020-bz-465143-cifs-turn-off-unicod.patch

Any chance that they are pushed on kernel 5.3 BA ?

Comment 7 Jeff Layton 2009-01-28 23:08:26 UTC
Doubtful that that will make a 5.3.z release. It's not causing a panic or security issue. It should make 5.4 though.

Comment 8 Tru Huynh 2009-01-28 23:28:06 UTC
thanks for your time and input. Meanwhile any one who needs to have it fixed will need to request a RHEL support case from their regular support channel.It's probably also there on 4.7 also, maybe it could be fixed for 4.8?

Correct.

I believe the patches in question are already in the CIFS update for 4.8.

Comment 10 Tru Huynh 2009-01-28 23:52:01 UTC
yes, it's on your list of patches for 4.8 at http://people.redhat.com/jlayton/
