If CONFIG_OF is not set, make of_mdiobus_register() call mdiobus_register() instead of returning -ENOSYS. This way, we can just call of_mdiobus_register() from all DT-enabled drivers to handle the compat cases.

Rajesh Borundia says: ==================== qlcnic: Bug fixes. This patch series contain following bug fixes. * Fix panic where driver was accessing un-initialized crb_intr_mask in non Multi-Tx queue mode while dumping TX queue. * Do not set netdev->real_num_tx_queues directly from driver instead use kernel defined netif_set_real_num_tx_queues() API. Also notify stack about change in number of Rx queues. Please apply this series to net. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

The jme driver forgot to check the return status from pci_map_page in its tx path, causing a dma api warning on unmap. Easy fix, just do the check and augment the tx path to tell the stack that the driver is busy so we re-queue the frame.

Florian Westphal says: ==================== net: ip: push gso skb forwarding handling down the stack Turns out doing the segmentation in forwarding was not a bright idea, there are corner-cases where this has unintended side-effects. This patch pushes the segmentation downwards. After this, netif_skb_dev_features() function can be removed again, it was only added to fetch the features of the output device, we can just use skb->dev after the pushdown. Tested with following setup: host -> kvm_router -> kvm_host mtu 1500 mtu1280 - 'host' has route to kvm_host with locked mtu of 1500 - gso/gro enabled on all interfaces Did tests with all of following combinations: - netfilter conntrack off and on on kvm_router - virtio-net and e1000 driver on kvm_router - tcp and udp bulk xmit from host to kvm_host for tcp, I added TCPMSS mangling on kvm_host to make it lie about tcp mss. Also added a dummy '-t mangle -A POSTROUTING -p udp -f' rule to make sure no udp fragments are seen in the 'conntrack on' and 'virtio-net' case. Also checked (with ping -M do -s 1400)' that it still sends the wanted icmp error message when size exceeds 1280. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Doing the segmentation in the forward path has one major drawback: When using virtio, we may process gso udp packets coming from host network stack. In that case, netfilter POSTROUTING will see one packet with udp header followed by multiple ip fragments. Delay the segmentation and do it after POSTROUTING invocation to avoid this.

If conntrack defragments incoming ipv6 frags it stores largest original frag size in ip6cb and sets ->local_df. We must thus first test the largest original frag size vs. mtu, and not vice versa. Without this patch PKTTOOBIG is still generated in ip6_fragment() later in the stack, but 1) IPSTATS_MIB_INTOOBIGERRORS won't increment 2) packet did (needlessly) traverse netfilter postrouting hook.

local_df means 'ignore DF bit if set', so if its set we're allowed to perform ip fragmentation. This wasn't noticed earlier because the output path also drops such skbs (and emits needed icmp error) and because netfilter ip defrag did not set local_df until couple of days ago. Only difference is that DF-packets-larger-than MTU now discarded earlier (f.e. we avoid pointless netfilter postrouting trip). While at it, drop the repeated test ip_exceeds_mtu, checking it once is enough...

Under "heavy" RX load, the driver cannot handle the descriptors fast enough. In detail, when a descriptor is consumed, its used flag is cleared and once the RX budget is consumed all descriptors with a cleared used flag are prepared to receive more data. Under load though, the HW may constantly receive more data and use those descriptors with a cleared used flag before they are actually prepared for next usage. The head and tail pointers into the RX-ring should always be valid and we can omit clearing and checking of the used flag.

In ip_tunnel_rcv(), set skb->network_header to inner IP header before IP_ECN_decapsulate(). Without the fix, IP_ECN_decapsulate() takes outer IP header as inner IP header, possibly causing error messages or packet drops. Note that this skb_reset_network_header() call was in this spot when the original feature for checking consistency of ECN bits through tunnels was added in eccc1bb8 ("tunnel: drop packet if ECN present with not-ECT"). It was only removed from this spot in 3d7b46cd ("ip_tunnel: push generic protocol handling to ip_tunnel module."). Fixes: 3d7b46cd ("ip_tunnel: push generic protocol handling to ip_tunnel module.")

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e1000e only. David provides four fixes for e1000e, first is a workaround for a hardware erratum on 82579 devices which experienced packet loss in gigabit and 100 speeds when interconnect between the PHY and MAC is exiting K1 power saving state. Second expands the scope of a workaround to include i217 and i218 parts as well to address over aggressive transmit behavior when connecting at 10Mbs half-duplex. Next is to resolve a reported link flap issue on 82579 parts which was root caused as an interoperability problem between 82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. Lastly, restricts the workaround of putting the PHY into MDIO slow mode to access the PHY id to relevant parts since this issue has been fixed on the newer hardware. ==================== Signed-off-by: David S.

Several customers have reported a link flap issue on 82579. The symptoms are random and intermittent link losses when 82579 is connected to specific link partners. Issue has been root caused as interoperability problem between 82579 and at least some Broadcom PHYs in the Energy Efficient Ethernet wake mechanism. To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M Low Power Idle. This solution will cause an increase of power in 100M EEE link. It will cost additional 28mW in this specific mode.

Problem: 82579 parts experience packet loss in Gig and 100 speeds when interconnect between PHY and MAC is exiting K1 power saving state.

Commit 4d619f62 ("net: cdc_ncm: no point in filling up the NTBs if we send ZLPs") changed the padding logic for devices with the ZLP flag set. This meant that frames of any size will be sent without additional padding, except for the single byte added if the size is a multiple of the USB packet size. But if the unpadded size is identical to the maximum frame size, and the maximum size is a multiplum of the USB packet size, then this one-byte padding will overflow the buffer. Prevent padding if already at maximum frame size, letting usbnet transmit a ZLP instead in this case.

Right now the core vsock module is the owner of the proto family. This means there's nothing preventing the transport module from unloading if there are open sockets, which results in a panic. Fix that by allowing the transport to be the owner, which will refcount it properly. Includes version bump to 1.0.1.0-k Passes checkpatch this time, I swear...

John W. Linville says: ==================== pull request: wireless 2014-05-01 Please pull the following batch of fixes intended for the 3.15 stream! For the Bluetooth bits, Gustavo says: "Some fixes for 3.15. There is a revert for the intel driver, a new device id, and two important SSP fixes from Johan." On top of that... Ben Hutchings gives us a fix for an unbalanced irq enable in an rtl8192cu error path. Colin Ian King provides an rtlwifi fix for an uninitialized variable. Felix Fietkau brings a pair of ath9k fixes, one that corrects a hardware initialization value and another that removes an (unnecessary) flag that was being used in a way that led to a software tx queue hang in ath9k. Gertjan van Wingerde pushes a MAINTAINERS change to remove himself from the rt2x00 maintainer team. Hans de Goede fixes a brcmfmac firmware load hang. Larry Finger changes rtlwifi to use the correct queue for V0 traffic on rtl8192se. Rajkumar Manoharan corrects a race in ath9k driver initialization. Stanislaw Gruszka fixes an rt2x00 bug in which disabling beaconing once on USB devices led to permanently disabling beaconing for those devices. Tim Harvey provides fixes for a pair of ath9k issues that can lead to soft lockups in that driver. Please let me know if there are problems! ==================== Signed-off-by: David S.
