* caif: Add support for CAIF over CDC NCM USB interfacesjur.brandeland@stericsson.com2011-12-05
| | | | | | | | | | | | | | | | | | | | | NCM 1.0 does not support anything but Ethernet framing, hence CAIF payload will be put into Ethernet frames. Discovery is based on fixed USB vendor 0x04cc (ST-Ericsson), product-id 0x230f (NCM). In this variant only CAIF payload is sent over the NCM interface. The CAIF stack (cfusbl.c) will when USB interface register first check if we got a CDC NCM USB interface with the right VID, PID. It will then read the device's Ethernet address and create a 'template' Ethernet TX header, using a broadcast address as the destination address, and EthType 0x88b5 (802.1 Local Experimental - vendor specific). A protocol handler for 0x88b5 is setup for reception of CAIF frames from the CDC NCM USB interface. Signed-off-by: Sjur Brændeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.

| * ixgbe: DCB: IEEE transitions may fail to reprogram hardware.John Fastabend2011-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transitioning through an IEEE DCBX version from a CEE DCBX and back (CEE->IEEE->CEE) may leave IEEE attributes programmed in the hardware. DCB uses a bit field in the set routines to determine which attributes PG, PFC, APP need to be reprogrammed. This is needed because user flow allows queueing a series of changes and then reprogramming the hardware with the entire set in one operation. When transitioning from IEEE DCBX mode back into CEE DCBX mode the PG and PFC bits need to be set so the possibly different CEE attributes get programmed into the device. This patch fixes broken logic that was evaluating to 0 and never setting any bits. Further this removes some checks for num_tc in set routines. This logic only worked when the number of traffic classes and user priorities were equal. This is no longer the case for X540 devices. Besides we can trust user input in this case if the device is incorrectly configured the DCB bandwidths will be incorrectly mapped but no OOPs, BUG, or hardware failure will occur.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The order of operations is important in DCBnl set_all(). When FCoE is configured it uses the up2tc map to learn which queues to configure the hardware offloads on. Therefore we need to setup the map before configuring FCoE. This is only seen when the both up2tc mappings and APP info are configured simultaneously.

| * e1000e: hitting BUG_ON() from napi_enableBruce Allan2011-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch from Mike McElroy created against the out-of-tree e1000e driver: Hitting the BUG_ON in napi_enable(). Code inspection shows that this can only be triggered by calling napi_enable() twice without an intervening napi_disable(). I saw the following sequence of events in the stack trace: 1) We simulated a cable pull using an Extreme switch. 2) e1000_tx_timeout() was entered. 3) e1000_reset_task() was called. Saw the message from e_err() in the console log. 4) e1000_reinit_locked was called. This function calls e1000_down() and e1000_up(). These functions call napi_disable() and napi_enable() respectively. 5) Then on another thread, a monitor task saw carrier was down and executed 'ip set link down' and 'ip set link up' commands. 6) Saw the '_E1000_RESETTING'warning fron the e1000_close function. 7) Either the e1000_open() executed between the e1000_down() and e1000_up() calls in step 4 or the e1000_open() call executed after the e1000_up() call. In either case, napi_enable() is called twice which triggers the BUG_ON.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We discovered that TCP stack could retransmit misaligned skbs if a malicious peer acknowledged sub MSS frame. This currently can happen only if output interface is non SG enabled : If SG is enabled, tcp builds headless skbs (all payload is included in fragments), so the tcp trimming process only removes parts of skb fragments, header stay aligned. Some arches cant handle misalignments, so force a head reallocation and shrink headroom to MAX_TCP_HEADER. Dont care about misaligments on x86 and PPC (or other arches setting NET_IP_ALIGN to 0) This patch introduces __pskb_copy() which can specify the headroom of new head, and pskb_copy() becomes a wrapper on top of __pskb_copy() Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Open vSwitch is a multilayer Ethernet switch targeted at virtualized environments. In addition to supporting a variety of features expected in a traditional hardware switch, it enables fine-grained programmatic extension and flow-based control of the network. This control is useful in a wide variety of applications but is particularly important in multi-server virtualization deployments, which are often characterized by highly dynamic endpoints and the need to maintain logical abstractions for multiple tenants. The Open vSwitch datapath provides an in-kernel fast path for packet forwarding. It is complemented by a userspace daemon, ovs-vswitchd, which is able to accept configuration from a variety of sources and translate it into packet processing rules.

RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit f2c31e32b378 (fix NULL dereferences in check_peer_redir()), dst_get_neighbour() should be guarded by rcu_read_lock() / rcu_read_unlock() section.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need rcu_read_lock() protection before using dst_get_neighbour(), and we must cache its value (pass it to __teql_resolve()) teql_master_xmit() is called under rcu_read_lock_bh() protection, its not enough.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 230dec6 (net/fec: add imx6q enet support) the FEC driver is no longer built by default for i.MX SoCs. Let the FEC driver be built by default again.
