CAIF HSI uses a timer for inactivity. Upon timeout HSI-wake signaling is initiated to allow power-down of the HSI block. Signed-off-by:

Some platforms do not allow to put HSI block into low-power mode when FIFO is not empty. The patch flushes (by reading) FIFO at wake down sequence. Asynchronous read and write is implemented for that. As a side effect this will also greatly improve performance. Signed-off-by:

Under stressed conditions a race could happen when del_timer_sync() was called from softirq context at the same time when mod_timer_pending() for the same timer was called from the workqueue. This leaded to a state mismatch in the CAIF HSI driver and following unexpected link wakeup procedure. The fix puts del_timer_sync() and mod_timer_pending() calls under a spin lock to protect against the race condition. Signed-off-by:

To ease skb->truesize sanitization, its better to be able to localize all references to skb frags size. Define accessors : skb_frag_size() to fetch frag size, and skb_frag_size_{set|add|sub}() to manipulate it. Signed-off-by:Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by:

Calling icmpv6_send() on a local message size error leads to an incorrect update of the path mtu. So use xfrm6_local_rxpmtu() to notify about the pmtu if the IPV6_DONTFRAG socket option is set on an udp or raw socket, according RFC 3542 and use ipv6_local_error() otherwise. Signed-off-by:

ip6_append_data() builds packets based on the mtu from dst_mtu(rt->dst.path). On IPsec the effective mtu is lower because we need to add the protocol headers and trailers later when we do the IPsec transformations. So after the IPsec transformations the packet might be too big, which leads to a slowpath fragmentation then. This patch fixes this by building the packets based on the lower IPsec mtu from dst_mtu(&rt->dst) and adapts the exthdr handling to this. Signed-off-by:

The pointer to mtu_info is taken from the common buffer of the skb, thus it can't be a NULL pointer. This patch removes this check on mtu_info. Signed-off-by:

The following configuration used to work as I expected. At least we could use the fcoe interfaces to do MPIO and the bond0 iface to do load balancing or failover. ---eth2.228-fcoe | eth2 -----| | |---- bond0 | eth3 -----| | ---eth3.228-fcoe This worked because of a change we added to allow inactive slaves to rx 'exact' matches. This functionality was kept intact with the rx_handler mechanism. However now the vlan interface attached to the active slave never receives traffic because the bonding rx_handler updates the skb->dev and goto's another_round. Previously, the vlan_do_receive() logic was called before the bonding rx_handler. Now by the time vlan_do_receive calls vlan_find_dev() the skb->dev is set to bond0 and it is clear no vlan is attached to this iface. The vlan lookup fails. This patch moves the VLAN check above the rx_handler. A VLAN tagged frame is now routed to the eth2.228-fcoe iface in the above schematic. Untagged frames continue to the bond0 as normal. This case also remains intact, eth2 --> bond0 --> vlan.228 Here the skb is VLAN tagged but the vlan lookup fails on eth2 causing the bonding rx_handler to be called. On the second pass the vlan lookup is on the bond0 iface and completes as expected. Putting a VLAN.228 on both the bond0 and eth2 device will result in eth2.228 receiving the skb. I don't think this is completely unexpected and was the result prior to the rx_handler result. Note, the same setup is also used for other storage traffic that MPIO is used with eg. iSCSI and similar setups can be contrived without storage protocols.

The cs89x0 driver was initial placed in the apple/ when it should have been placed in the cirrus/. This resolves the issue by moving the dirver and fixing up the respective Kconfig(s) and Makefile(s). Thanks to Sascha for reporting the issue. -v2 Fix a config error that was introduced with v1 by removing the dependency on MACE for NET_VENDOR_APPLE.

pppol2tp_xmit() calls skb_cow_head(skb, 2) before calling l2tp_xmit_skb() Then l2tp_xmit_skb() calls again skb_cow_head(skb, large_headroom) This patchs changes the first skb_cow_head() call to supply the needed headroom to make sure at most one (expensive) pskb_expand_head() is done.

Based on a patch from Michael Ellerman, clean up a significant portion of the transmit path. There was a lot of duplication here. Even worse, we were always checksumming tx packets and ignoring the skb->ip_summed field. Also remove NETIF_F_FRAGLIST from dev->features, I'm not sure why it was enabled. Signed-off-by:

The ehea adapter has a mode where it will avoid partial cacheline DMA writes on receive by always padding packets to fall on a cacheline boundary. Unfortunately we currently aren't allocating enough space for a full ethernet MTU packet to be rounded up, so this optimisation doesn't hit. It's unfortunate that the next largest packet size exposed by the hypervisor interface is 2kB, meaning our skb allocation comes out of a 4kB SLAB. However the performance increase due to this optimisation is quite large and my TCP stream numbers increase from 900MB to 1000MB/sec. Signed-off-by:
