2014-05-05net/mlx4_core: Load the Eth driver firstOr Gerlitz
When running in SRIOV mode, VM that is assigned with a non-provisioned Ethernet VFs get themselves a random mac when the Eth driver starts. In this case, if the IB driver startup code that deals with RoCE runs first, it will use a zero mac as the source mac for the Para-Virtual CM MADs which is buggy. To handle that, we change the order of loading. Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-05net/mlx4_core: Fix slave id computation for single port VFMatan Barak
The code that deals with computing the slave id based on a given GID gave wrong results when the number of single port VFs wasn't the same for port 1 vs. port 2 and the relevant VF is single ported on port 2. As a result, incoming CM MADs were dispatched to the wrong VF. Fixed that and added documentation to clarify the computation steps.

2014-05-05net: cdc_ncm: fix buffer overflowBjørn Mork
Commit 4d619f625a60 ("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.

2014-04-30gianfar: Avoid unnecessary reg accesses in adjust_link()Claudiu Manoil
For phy devices that don't issue interrupts upon link state changes, phylib polls the link state resulting in repeated calls to adjust_link(), even if the link state didn't change. As a result, some mac registers are repeatedly read and written with the same values, which is not ok. To fix this, adjust_link() has been refactored to check first whether the link state has changed and to take action only if needed, updating mac registers and local state variables. The 'new_state' local flag, set if one of the link params changed (link, speed or duplex), has been rendered useless and removed by this refactoring.

2014-04-30tcp_cubic: fix the range of delayed_ackLiu Yu
commit b9f47a3aaeab (tcp_cubic: limit delayed_ack ratio to prevent divide error) try to prevent divide error, but there is still a little chance that delayed_ack can reach zero. In case the param cnt get negative value, then ratio+cnt would overflow and may happen to be zero. As a result, min(ratio, ACK_RATIO_LIMIT) will calculate to be zero. In some old kernels, such as 2.6.32, there is a bug that would pass negative param, which then ultimately leads to this divide error. commit 5b35e1e6e9c (tcp: fix tcp_trim_head() to adjust segment count with skb MSS) fixed the negative param issue. However, it's safe that we fix the range of delayed_ack as well, to make sure we do not hit a divide by zero.

2014-04-30Revert "macvlan : fix checksums error when we are in bridge mode"Vlad Yasevich
This reverts commit 12a2856b604476c27d85a5f9a57ae1661fc46019. The commit above doesn't appear to be necessary any more as the checksums appear to be correctly computed/validated. Additionally the above commit breaks kvm configurations where one VM is using a device that support checksum offload (virtio) and the other VM does not. In this case, packets leaving virtio device will have CHECKSUM_PARTIAL set. The packets is forwarded to a macvtap that has offload features turned off. Since we use CHECKSUM_UNNECESSARY, the host does does not update the checksum and thus a bad checksum is passed up to the guest.

2014-04-30mactap: Fix checksum errors for non-gso packets in bridge modeVlad Yasevich
The following is a problematic configuration: VM1: virtio-net device connected to macvtap0@eth0 VM2: e1000 device connect to macvtap1@eth0 The problem is is that virtio-net supports checksum offloading and thus sends the packets to the host with CHECKSUM_PARTIAL set. On the other hand, e1000 does not support any acceleration. For small TCP packets (and this includes the 3-way handshake), e1000 ends up receiving packets that only have a partial checksum set. This causes TCP to fail checksum validation and to drop packets. As a result tcp connections can not be established. Commit 3e4f8b787370978733ca6cae452720a4f0c296b8 macvtap: Perform GSO on forwarding path. fixes this issue for large packets wthat will end up undergoing GSO. This commit adds a check for the non-GSO case and attempts to compute the checksum for partially checksummed packets in the non-GSO case.

2014-04-27sctp: reset flowi4_oif parameter on route lookupXufeng Zhang
commit 813b3b5db83 (ipv4: Use caller's on-stack flowi as-is in output route lookups.) introduces another regression which is very similar to the problem of commit e6b45241c (ipv4: reset flowi parameters on route connect) wants to fix: Before we call ip_route_output_key() in sctp_v4_get_dst() to get a dst that matches a bind address as the source address, we have already called this function previously and the flowi parameters have been initialized including flowi4_oif, so when we call this function again, the process in __ip_route_output_key() will be different because of the setting of flowi4_oif, and we'll get a networking device which corresponds to the inputted flowi4_oif as the output device, this is wrong because we'll never hit this place if the previously returned source address of dst match one of the bound addresses. To reproduce this problem, a vlan setting is enough: # ifconfig eth0 up # route del default # vconfig add eth0 2 # vconfig add eth0 3 # ifconfig eth0.2 10.0.1.14 netmask 255.255.255.0 # route add default gw 10.0.1.254 dev eth0.2 # ifconfig eth0.3 10.0.0.14 netmask 255.255.255.0 # ip rule add from 10.0.0.14 table 4 # ip route add table 4 default via 10.0.0.254 src 10.0.0.14 dev eth0.3 # sctp_darn -H 10.0.0.14 -P 36422 -h 10.1.4.134 -p 36422 -s -I You'll detect that all the flow are routed to eth0.2(10.0.1.254).

2014-04-27bridge: Handle IFLA_ADDRESS correctly when creating bridge deviceToshiaki Makita
When bridge device is created with IFLA_ADDRESS, we are not calling br_stp_change_bridge_id(), which leads to incorrect local fdb management and bridge id calculation, and prevents us from receiving frames on the bridge device.

2014-04-26i40e: fix Timesync Tx interrupt handler codeJacob Keller
This patch fixes the PTP Tx timestamp interrupt handler. The original code misinterpreted the interrupt handler design. We were clearing the ena_mask bit for the Timesync interrupts. This is done to indicate that the interrupt will be handled in a scheduled work item (instead of immediately) and that work item is responsible for re-enabling the interrupts. However, the Tx timestamp was being handled immediately and nothing was ever re-enabling it. This resulted in a single interrupt working for the life of the driver. This patch fixes the issue by instead clearing the bit from icr0 which is used to indicate that the interrupt was immediately handled and can be re-enabled right away. This patch also clears up a related issue due to writing the PRTTSYN_STAT_0 register, which was unintentionally clearing the cause bits for Timesync interrupts.

git://gitorious.org/linux-can/linux-can Marc Kleine-Budde says: ==================== this is a pull request for net/master, for the v3.15 release cycle, consisting of 26 patches. Thomas Gleixner contributes 21 patches for the c_can driver, which address several shortcomings in the driver like hardware initialisation, concurrency, message ordering and poor performance. Two patches Oliver Hartkopp, one adds a missing lock to the sja1000_isa driver, the other one fixes the return value in the generic bit time configuration function. And finally a patch by Alexander Stein, that fixes the slcan driver to use the correct spinlock variant. To make it 26 patches, Wolfgang Grandegger patch for the c_can_pci driver, which enables the bus master only for MSI and a patch by Wolfram Sang, which converts the 'instance' in the c_can driver to the proper type. ==================== Signed-off-by: David S.

2014-04-26Merge branch 'altera_tse'David S. Miller
Vince Bridgers says: ==================== This series of patches addresses a handful of issues found in testing and reported by users of the Altera Triple Speed Ethernet soft IP. The patches address the following issues (in summary) 1) The SGDMA soft IP was found to incorrectly process receive packets when the target physical address of the receive buffer was on a boundary that's not 32-bit aligned. One of the patches addresses this issue. 2) The pause quanta was not being set by the driver, one patch of this series sets the pause quanta to the IEEE defined default value since the hardware reset value is 0. 3) An issue in a error recovery path of the probe routine caused a kernel panic in the event a phy was probed and could not be found. A patch addresses this issue. 4) A change was made to the driver name for Ethtool support, and comments added to support an addition to Ethtool to support the Altera Triple Speed Ethernet controller. ==================== Signed-off-by: David S.
