Patches Part 1
daemon@ATHENA.MIT.EDU (Alan Cox)
Mon Sep 4 22:30:48 1995
Date: Mon, 4 Sep 1995 10:47:04 +0100
From: Alan Cox <alan@cymru.net>
To: linux-net@vger.rutgers.edu, torvalds@cs.Helsinki.FI
*
* Mixed small fixes.
*
* The 0 length fragment/Solaris NFS bug
* Full BSD (arbitary length write) semantics on AF_UNIX stream
* The IGMP include diff I forgot to include last time
* AF_UNIX performance improvments
* Netrom sendmsg/recvmsg
* Improved iovec handling - now leaves iovec so further calls
* copy further data. Need to add memcpy_offset_fromiovec for
* AF_INET still.
*
*
* Linus what is the state on
*
* 1. Paul Gortmakers 8390 copy and checksum
* 2. His cleaned up timeout handling for net devices
* 3. sysctl() - I really need sysctl soon
*
* Other net channel people
*
* Tom May: Is there a final insw_and_checksum conclusion/code ?
*
*
* Please ACK the receipt of this, just so I know no mail
* is getting dropped.
*
