2014-01-09xen-netback: stop vif thread spinning if frontend is unresponsivePaul Durrant
The recent patch to improve guest receive side flow control (ca2f09f2) had a slight flaw in the wait condition for the vif thread in that any remaining skbs in the guest receive side netback internal queue would prevent the thread from sleeping. An unresponsive frontend can lead to a permanently non-empty internal queue and thus the thread will spin. In this case the thread should really sleep until the frontend becomes responsive again. This patch adds an extra flag to the vif which is set if the shared ring is full and cleared when skbs are drained into the shared ring. Thus, if the thread runs, finds the shared ring full and can make no progress the flag remains set. If the flag remains set then the thread will sleep, regardless of a non-empty queue, until the next event from the frontend.

2014-01-06vxlan: keep original skb ownershipEric Dumazet
Sathya Perla posted a patch trying to address following problem : <quote> The vxlan driver sets itself as the socket owner for all the TX flows it encapsulates (using vxlan_set_owner()) and assigns it's own skb destructor. This causes all tunneled traffic to land up on only one TXQ as all encapsulated skbs refer to the vxlan socket and not the original socket. Also, the vxlan skb destructor breaks some functionality for tunneled traffic like wmem accounting and as TCP small queues and FQ/pacing packet scheduler. </quote> I reworked Sathya patch and added some explanations. vxlan_xmit() can avoid one skb_clone()/dev_kfree_skb() pair and gain better drop monitor accuracy, by calling kfree_skb() when appropriate. The UDP socket used by vxlan to perform encapsulation of xmit packets do not need to be alive while packets leave vxlan code. Its better to keep original socket ownership to get proper feedback from qdisc and NIC layers. We use skb->sk to A) control amount of bytes/packets queued on behalf of a socket, but prior vxlan code did the skb->sk transfert without any limit/control on vxlan socket sk_sndbuf. B) security purposes (as selinux) or netfilter uses, and I do not think anything is prepared to handle vxlan stacked case in this area. By not changing ownership, vxlan tunnels behave like other tunnels. As Stephen mentioned, we might do the same change in L2TP.

2014-01-06hso: fix handling of modem port SERIAL_STATE notificationsDan Williams
The existing serial state notification handling expected older Option devices, having a hardcoded assumption that the Modem port was always USB interface #2. That isn't true for devices from the past few years. hso_serial_state_notification is a local cache of a USB Communications Interface Class SERIAL_STATE notification from the device, and the USB CDC specification (section 6.3, table 67 "Class-Specific Notifications") defines wIndex as the USB interface the event applies to. For hso devices this will always be the Modem port, as the Modem port is the only port which is set up to receive them by the driver. So instead of always expecting USB interface #2, instead validate the notification with the actual USB interface number of the Modem port. Signed-off-by: Dan Williams <dcbw@redhat.com> Tested-by: H.
