Mangling IP Options fields

[Quinton Hoole]

Hi Jonas

Thanks for your kind offer of help! I assume you meant it ;-)  If so, 
here goes...

I've been struggling to get a working development platform, and finally 
have a Fedora Core 3 system, with kernel-2.6.11-1.14_FC3, which I've 
built from source and tested.

Now I try to use patch-o-matic to apply the IPV4OPTSSTRIP patch, but get 
the following error:
===================
Do you want to apply this patch [N/y/t/f/a/r/b/w/q/?] y
Testing patch base/IPV4OPTSSTRIP.patch...
Warning - no help text file could be found in either
/usr/src/linux/net/ipv4/netfilter/Config.help
or /usr/src/linux/Documentation/Configure.help
fgrep: /usr/src/linux/net/ipv4/netfilter/Config.in: No such file or 
directory
Could not find place to slot in Config.in line
TEST FAILED: patch NOT applied.
===================

I installed the kernel source RPM according to the instructions in the 
FC3  (http://fedora.redhat.com/docs/release-notes/fc3/x86/), which 
places  the kernel source in

/usr/src/redhat/BUILD/kernel-2.6.11/linux-2.6.11

For convenience I  created a symbolic link from /usr/src/linux to the above.

Then by executing the following I got the error above:
[root at quinton-lap1 patch-o-matic]# KERNEL_DIR=/usr/src/linux ./runme base

What am I doing wrong?  Should I be using a standard kernel from 
kernel.org, rather than my FC3 kernel?
