virtio declares support for NETIF_F_FRAGLIST, but assumes that there are at most MAX_SKB_FRAGS + 2 fragments which isn't always true with a fraglist. A longer fraglist in the skb will make the call to skb_to_sgvec overflow the sg array, leading to memory corruption. Drop NETIF_F_FRAGLIST so we only get what we can handle. Cc: Michael S...

In my Linux VM, I am unable to change scatter-gather / tx-checksumming / TCP-segmentation offload features by ethtool command. I am using virtio nic with vhostuser port backend. It shows me an error: Cannot change tx-checksumming Cannot change scatter-gather Cannot change tcp-segmentation offload Could not change any device features Ony running command ethtool -k ens3, I get the following:

When I was preparing Xen''s netback driver for upstream one of the things I removed was the zero-copy guest transmit (i.e. netback receive) support. In this mode guest data pages ("foreign pages") were mapped into the backend domain (using Xen grant-table functionality) and placed into the skb''s paged frag list (skb_shinfo(skb)->frags, I hope I am using the right

Hi all, This patchset makes some key modifications to the original ''stable page writes'' patchset. First, it provides users (devices and filesystems) of a backing_dev_info the ability to declare whether or not it is necessary to ensure that page contents cannot change during writeout, whereas the current code assumes that this is true. Second, it relaxes the

Hi all, I was intending on trying out gjournal on a new disk i've added in my desktop. I had a look to see what the most recent patch provided by Pawel and found http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch I created the directories as per Pawel's original post (http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html) and the patch succeeded with no failed
