[0/6] [NET]: virtio SG/TSO patches
Hi: Here are the patches I used for testing KVM with virtio-net using TSO. There are three patches for the tun device which are basically Rusty's patches with the mmap turned into copying (for correctness). Two patches are for the virtio-net frontend, one required to support receiving SG/TSO, and the other useful for testing SG per se. The other patch is to the KVM backend to make all this

[PATCH 1/4] virtio: wean net driver off NETDEV_TX_BUSY
Herbert tells me that returning NETDEV_TX_BUSY from hard_start_xmit is seen as a poor thing to do; we should cache the packet and stop the queue.

RFC: [0/2] Remove netloop by lazy copying in netback
Hi Keir: These two patches remove the need for netloop by performing the copying in netback and only if it is necessary. The rationale is that most packets will be processed without delay allowing them to be freed without copying at all. So instead of copying every packet destined to dom0 we''ll only copy those that linger longer than a specified amount of time (currently 0.5s). As it

[NET] front: Fix features on resume when csum is off
Hi Keir: [NET] front: Fix features on resume when csum is off When the netfront driver is resumed the features are renegotiated with the backend. However, I forgot take into account the status of the TX checksum setting. When TX checksum is disabled by the user, we cannot enable SG or TSO since both require checksum offload. This patch makes xennet check the checksum setting before

Xen netfront fixes for changed skbuff in net-2.6.22.git
Hi Herbert, I wonder if you''ve got a chance to look at netfront in light of the new stuff in davem''s network tree (the stuff that''s in http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.22.git). In particular, struct sk_buff has been changed so that "nh" has gone, and the replacement can be just an offset rather than a full pointer. This breaks the

qemu/rtl8139: Max transmit frame size
Hi: I noticed a bug in the realloc error checking code in the QEMU backend for RealTek8139. However, what''s worse is that there is no cap on the total size of the transmit buffer at all. So a guest can keep extending it until memory runs out. CP_TX_BUFFER_SIZE is already 64K. So it seems to me that we don''t need the while loop to extend the buffer at all since no transmitted

[PATCH] Fix bashism in scripts/Makefile.xen
Hi: The following patch replaces a bash-specific substitution with equivalent POSIX /bin/sh substitutions. This allows a Xen-patched Linux to build when /bin/sh is a POSIX shell other than bash.

vm_map_xen_pages removal breaks modular oprofile
Hi Keir: It has been brought to my attention that modular oprofile is broken because it now calls get_vm_area which is not an exported function. This appears to be the result of the changeset that removed vm_map_xen_pages which was only used by oprofile. So we either need to export get_vm_area in Xen, or put that function back. What do you think about this? Thanks, -- Visit Openswan at

[PATCH 1/2] virtio-net: don't disable guest csum when disable LRO
From: Tonghao Zhang <xiangxia.m.yue at gmail.com> Open vSwitch and Linux bridge will disable LRO of the interface when this interface added to them. Now when disable the LRO, the virtio-net csum is disable too. That drops the forwarding performance. Fixes: e59ff2c49ae1 ("virtio-net: disable guest csum during XDP set") Cc: Michael S.

Discussing `dash' in klibc mailing list
Peter, i ask you to permit discussion of `dash' in the klibc list. Pulled reasons are, that bugs and followups are distributed in bug tracking systems with arbitrary decisions. In the klibc there are also changes, that can be discussed widely, and opinions with possible solutions published. So far i have two problems. First is proposed change for test(1):

[Bridge] [PATCH] Remove rcu_assign_pointer() penalty for NULL pointers
Hello! The rcu_assign_pointer() primitive currently unconditionally executes a memory barrier, even when a NULL pointer is being assigned. This has lead some to avoid using rcu_assign_pointer() for NULL pointers, which loses the self-documenting advantages of rcu_assign_pointer() This patch uses __builtin_const_p() to omit needless memory barriers for NULL-pointer assignments at compile time
