Subject: [UPDATE] Zerocopy 2.4.1 rev 3


You know where to get it:

ftp://ftp.kernel.org/pub/linux/kernel/people/davem/zerocopy-2.4.1-3.diff.gz

Fixes:

1) pskb_expand_tail could corrupt SKB frag lists in some
cases, leading to OOPS

2) Need to check for out of window data even in the
partial packet cases of tcp_data_queue

3) Merged in some small net fixes from the AC patches.

As of this moment, I know of no bugs (ie. corrupts data or crashes
kernel) in the zerocopy patches.

Some people have asked me about making a patch against the AC
patches. It is doable, but would be quite a bit of work for me.

If someone would like to do this and put those patches up somewhere,
they can feel free to do so. Just let everyone on linux-kernel
and netdev know about it. Probably, after the next zerocopy patch
revision, I will ask Alan to add the zerocopy stuff to his tree
anyways. Things really look good right now.

Thanks.

Later,
David S. Miller
