The .match_method field is a u8, so we shouldn't be casting to a u16, and because it is only one byte, we do not need to byte swap anything. Just assign the value directly.

2016-12-10net: phy: phy drivers should not set SUPPORTED_[Asym_]PauseTimur Tabi
Instead of having individual PHY drivers set the SUPPORTED_Pause and SUPPORTED_Asym_Pause flags, phylib itself should set those flags, unless there is a hardware erratum or other special case. During autonegotiation, the PHYs will determine whether to enable pause frame support. Pause frames are a feature that is supported by the MAC. It is the MAC that generates the frames and that processes them. The PHY can only be configured to allow them to pass through. This commit also effectively reverts the recently applied c7a61319 ("net: phy: dp83848: Support ethernet pause frames"). So the new process is: 1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause and SUPPORTED_AsymPause bits in phydev->supported. This indicates that the PHY supports pause frames. 2) The MAC driver checks phydev->supported before it calls phy_start(). If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver sets those bits in phydev->advertising, if it wants to enable pause frame support. 3) When the link state changes, the MAC driver checks phydev->pause and phydev->asym_pause, If the bits are set, then it enables the corresponding features in the MAC. The algorithm is: if (phydev->pause) The MAC should be programmed to receive and honor pause frames it receives, i.e. enable receive flow control. if (phydev->pause != phydev->asym_pause) The MAC should be programmed to transmit pause frames when needed, i.e. enable transmit flow control.

2016-12-10net: ethernet: stmmac: remove private tx queue lockLino Sanfilippo
The driver uses a private lock for synchronization of the xmit function and the xmit completion handler, but since the NETIF_F_LLTX flag is not set, the xmit function is also called with the xmit_lock held. On the other hand the completion handler uses the reverse locking order by first taking the private lock and (in case that the tx queue had been stopped) then the xmit_lock. Improve the locking by removing the private lock and using only the xmit_lock for synchronization instead. Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: David S.

2016-12-09ibmveth: set correct gso_size and gso_typeThomas Falcon
This patch is based on an earlier one submitted by Jon Maxwell with the following commit message: "We recently encountered a bug where a few customers using ibmveth on the same LPAR hit an issue where a TCP session hung when large receive was enabled. Closer analysis revealed that the session was stuck because the one side was advertising a zero window repeatedly. We narrowed this down to the fact the ibmveth driver did not set gso_size which is translated by TCP into the MSS later up the stack. The MSS is used to calculate the TCP window size and as that was abnormally large, it was calculating a zero window, even although the sockets receive buffer was completely empty." We rely on the Virtual I/O Server partition in a pseries environment to provide the MSS through the TCP header checksum field. The stipulation is that users should not disable checksum offloading if rx packet aggregation is enabled through VIOS. Some firmware offerings provide the MSS in the RX buffer. This is signalled by a bit in the RX queue descriptor.

2016-12-09net: qcom/emac: add support for the Qualcomm Technologies QDF2400Timur Tabi
The QDF2432 and the QDF2400 have slightly different internal PHYs, so there are some programming differences. Some of the registers in the QDF2400 have moved, and some registers require different values during initialization. Because of the differences, and because HIDs are a scare resource, the ACPI tables specify the hardware version in an _HRV property. Version 1 is the QDF2432, and version 2 is the QDF2400. Any future SOC that has the same internal PHY but different programming requirements will be assigned the next available version number.

2016-12-09net: qcom/emac: move phy init code to separate filesTimur Tabi
The internal PHY of the EMAC differs on each SOC, and the list will only continue to grow. By separating the code into individual files, we can add support for more SOCs more cleanly. Note: The internal PHY is also sometimes called the SGMII device. We also stop referring to the various PHY variations by version number, so no more "v2", "v3", etc. Instead, the devices are named after the SOC they are, which is in sync with the device tree property names. Future patches will probably rearrange more code among the files. Signed-off-by: Timur Tabi <timur@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

I consider these urgent enough to send for 4.9 consideration since they fix the kernel's handling of ARS (Address Range Scrub) commands. Especially for platforms without machine-check-recovery capabilities, successful execution of ARS commands enables the platform to potentially break out of an infinite reboot problem if a media error is present in the boot path. There is also a one line fix for a device-dax read-only mapping regression. Commits 9a901f5495e2 ("acpi, nfit: fix extended status translations for ACPI DSMs") and 325896ffdf90 ("device-dax: fix private mapping restriction, permit read-only") are true regression fixes for changes introduced this cycle. Commit efda1b5d87cb ("acpi, nfit, libnvdimm: fix / harden ars_status output length handling") fixes the kernel's handling of zero-length results, this never would have worked in the past, but we only just recently discovered a BIOS implementation that emits this arguably spec non-compliant result. The remaining two commits are additional fall out from thinking through the implications of a zero / truncated length result of the ARS Status command. In order to mitigate the risk that these changes introduce yet more regressions they are backstopped by a new unit test in commit a7de92dac9f0 ("tools/testing/nvdimm: unit test acpi_nfit_ctl()") that mocks up inputs to acpi_nfit_ctl()" * 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: device-dax: fix private mapping restriction, permit read-only tools/testing/nvdimm: unit test acpi_nfit_ctl() acpi, nfit: fix bus vs dimm confusion in xlat_status acpi, nfit: validate ars_status output buffer size acpi, nfit, libnvdimm: fix / harden ars_status output length handling acpi, nfit: fix extended status translations for ACPI DSMs

git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next Johan Hedberg says: ==================== pull request: bluetooth-next 2016-12-08 I didn't miss your "net-next is closed" email, but it did come as a bit of a surprise, and due to time-zone differences I didn't have a chance to react to it until now. We would have had a couple of patches in bluetooth-next that we'd still have wanted to get to 4.10. Out of these the most critical one is the H7/CT2 patch for Bluetooth Security Manager Protocol, something that couldn't be published before the Bluetooth 5.0 specification went public (yesterday). If these really can't go to net-next we'll likely be sending at least this patch through bluetooth.git to net.git for rc1 inclusion. ==================== Signed-off-by: David S.

2016-12-08mlx4: xdp: Reserve headroom for receiving packet when XDP prog is activeMartin KaFai Lau
Reserve XDP_PACKET_HEADROOM for packet and enable bpf_xdp_adjust_head() support. This patch only affects the code path when XDP is active. After testing, the tx_dropped counter is incremented if the xdp_prog sends more than wire MTU.

2016-12-08mlx4: xdp: Allow raising MTU up to one page minus eth and vlan hdrsMartin KaFai Lau
When XDP is active in mlx4, mlx4 is using one page/pkt. At the same time (i.e. when XDP is active), it is currently limiting MTU to be FRAG_SZ0 - ETH_HLEN - (2 * VLAN_HLEN) which is 1514 in x86. AFAICT, we can at least raise the MTU limit up to PAGE_SIZE - ETH_HLEN - (2 * VLAN_HLEN) which this patch is doing. It will be useful in the next patch which allows XDP program to extend the packet by adding new header(s). Note: In the earlier XDP patches, there is already existing guard to ensure the page/pkt scheme only applies when XDP is active in mlx4.

2016-12-08bpf: xdp: Allow head adjustment in XDP progMartin KaFai Lau
This patch allows XDP prog to extend/remove the packet data at the head (like adding or removing header). It is done by adding a new XDP helper bpf_xdp_adjust_head(). It also renames bpf_helper_changes_skb_data() to bpf_helper_changes_pkt_data() to better reflect that XDP prog does not work on skb. This patch adds one "xdp_adjust_head" bit to bpf_prog for the XDP-capable driver to check if the XDP prog requires bpf_xdp_adjust_head() support. The driver can then decide to error out during XDP_SETUP_PROG.
