From 0a1ec07a67bd8b0033dace237249654d015efa21 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 20 Apr 2009 01:25:46 +0000 Subject: net: skb_copy_datagram_const_iovec() There's an skb_copy_datagram_iovec() to copy out of a paged skb, but it modifies the iovec, and does not support starting at an offset in the destination. We want both in tun.c, so let's add the function. It's a carbon copy of skb_copy_datagram_iovec() with enough changes to be annoying. Signed-off-by: Michael S. Tsirkin Signed-off-by: David S.

Tsirkin" Date: Mon, 20 Apr 2009 01:26:11 +0000 Subject: tun: fix tun_chr_aio_write so that aio works aio_write gets const struct iovec * but tun_chr_aio_write casts this to struct iovec * and modifies the iovec. As a result, attempts to use io_submit to send packets to a tun device fail with weird errors such as EINVAL. Since tun is the only user of skb_copy_datagram_from_iovec, we can fix this simply by changing the later so that it does not touch the iovec passed to it. Signed-off-by: Michael S.
