Red Hat Bugzilla – Bug 135548
Please include CIFS support in RHEL 3.0 kernel

Description of problem:
Red Hat have stated that they will support Red Hat Enterprise Linux
3.0 until October 31st 2008.
However, many organisations (including my own) are currently
replacing Windows NT4.0 servers with Windows 2003 servers. Shares on
these machines are not accessible via the smbfs, but are accessible
via the cifs module. Therefore cifs support needs to be built into
I have created my own kernel rpm that includes CIFS support (and no
other changes). I'm willing to attach a copy if that helps.
Note that this uses version 1.20c and not the 1.0.2b that is stated
on the above site at present.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Red Hat Enterprise Linux 3.0
2. Try to connect to a Windows 2003 share
Actual Results: cli_negprot: SMB signing is mandatory and we have
10312: protocol negotiation failed
SMB connection failed
Expected Results: A mounted share like
//server/share on /mnt/server/share type cifs (rw,mand)
This not just an enhancement, it's vital for business that are using
Linux to connect to Windows shares.
Same issue in our business. RedHat should provide workaround if no
kernel module will be available.
There is a potential workaround mentioned at
http://www.w00tlinux.com/bb/sutra256692.html - see the first reply to the query.
The workaround isn't really acceptable if you care about the security of your
data. In the UK many organisations are expected to take all necessary steps to
secure their data, under the 1998 Data Protection Act. Disabling security is
therefore not an option.
At the moment I'm recompiling the kernel to include the CIFS module. Since this
is a module that you can either have running or not, I can't see how this would
affect any current usage of the kernel. I'm well aware of the reasons for
backporting security updates as it avoids breaking existing vendors software,
but I don't think this applies in this case. Can you say otherwise?
I can see that this module is included in the 2.6 kernel, and I do think that
this is one of the 2.6 features that should be put into 2.4. I'm already using
it, and it works great!
This bug is filed against RHEL 3, which is in maintenance phase.
During the maintenance phase, only security errata and select mission
critical bug fixes will be released for enterprise products. Since
this bug does not meet that criteria, it is now being closed.

support representative. You may be asked to provide detailed
information on how this bug is affecting you.
