2018-12-21serial/sunsu: fix refcount leakYangtao Li1-5/+26
The function of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. su_get_type() doesn't do that. The match node are used as an identifier to compare against the current node, so we can directly drop the refcount after getting the node from the path as it is not used as pointer. Fix this by use a single variable and drop the refcount right after of_find_node_by_path(). Signed-off-by: Yangtao Li <tiny.windzz@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The current implementation of elan_i2c is known to not support those 2 laptops. A proper fix is to tweak both elantech and elan_i2c to transmit the correct information from PS/2, which would make a bad candidate for stable.

The gpio IP on Armada 370 at offset 0x18180 has neither a clk nor pwm registers. So there is no need for a clk as the pwm isn't used anyhow.

2018-12-21gpio: gpio-omap: Revert deferred wakeup quirk handling for regressionsTony Lindgren1-59/+5
Commit ec0daae685b2 ("gpio: omap: Add level wakeup handling for omap4 based SoCs") attempted to fix omap4 GPIO wakeup handling as it was blocking deeper SoC idle states. However this caused a regression for GPIOs during runtime having over second long latencies for Ethernet GPIO interrupt as reportedy by Russell King <rmk+kernel@armlinux.org.uk>. Let's fix this issue by doing a partial revert of the breaking commit. We still want to keep the quirk handling around as it is also used for OMAP_GPIO_QUIRK_IDLE_REMOVE_TRIGGER. The real fix for omap4 GPIO wakeup handling involves fixes for omap_set_gpio_trigger() and omap_gpio_unmask_irq() and will be posted separately. And we must keep the wakeup bit enabled during runtime because of module doing clock autogating with autoidle configured.

2018-12-20net/mlx5e: XDP, Support Enhanced Multi-Packet TX WQETariq Toukan4-27/+173
Add support for the HW feature of multi-packet WQE in XDP xmit flow. The conventional TX descriptor (WQE, Work Queue Element) serves a single packet. Our HW has support for multi-packet WQE (MPWQE) in which a single descriptor serves multiple TX packets. This reduces both the PCI overhead and the CPU cycles wasted on writing them. In this patch we add support for the HW feature, which is supported starting from ConnectX-5. Performance: Tested packet rate for UDP 64Byte multi-stream over ConnectX-5 NICs. CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz XDP_TX: We see a huge gain on single port ConnectX-5, and reach the 100 Mpps milestone. * Single-port HCA: Before: 70 Mpps After: 100 Mpps (+42.8%) * Dual-port HCA: Before: 51.7 Mpps After: 57.3 Mpps (+10.8%) * In both cases we tested traffic on one port and for now On Dual-port HCAs we see only small gain, we are working to overcome this bottleneck, but for the moment only with experimental firmware on dual port HCAs we can reach the wanted numbers as seen on Single-port HCAs. XDP_REDIRECT: Redirect from (A) ConnectX-5 to (B) ConnectX-5. Due to a setup limitation, (A) and (B) are on different NUMA nodes, so absolute performance numbers are not optimal. Note: Below is the transmit rate of (B), not the redirect rate of (A) which is in some cases higher. * (B) is single-port: Before: 77 Mpps After: 90 Mpps (+16.8%) * (B) is dual-port: Before: 61 Mpps After: 72 Mpps (+18%) Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2018-12-20virtio-net: ethtool configurable LROWillem de Bruijn1-0/+33
Virtio-net devices negotiate LRO support with the host. Display the initially negotiated state with ethtool -k. Also allow configuring it with ethtool -K, reusing the existing virtnet_set_guest_offloads helper that configures LRO for XDP. This is conditional on VIRTIO_NET_F_CTRL_GUEST_OFFLOADS. Virtio-net negotiates TSO4 and TSO6 separately, but ethtool does not distinguish between the two. Display LRO as on only if any offload is active. RTNL is held while calling virtnet_set_features, same as on the path from virtnet_xdp_set. Changes v1 -> v2 - allow ethtool config (-K) only if VIRTIO_NET_F_CTRL_GUEST_OFFLOADS - show LRO as enabled if any LRO variant is enabled - do not allow configuration while XDP is active - differentiate current features from the capable set, to restore on XDP down only those features that were active on XDP up - move test out of VIRTIO_NET_F_CSUM/TSO branch, which is tx only Signed-off-by: Willem de Bruijn <willemb@google.com> Acked-by: Michael S.

2018-12-20ppp: Move PFC decompression to PPP generic layerSam Protsenko4-20/+62
Extract "Protocol" field decompression code from transport protocols to PPP generic layer, where it actually belongs. As a consequence, this patch fixes incorrect place of PFC decompression in L2TP driver (when it's not PPPOX_BOUND) and also enables this decompression for other protocols, like PPPoE. Protocol field decompression also happens in PPP Multilink Protocol code and in PPP compression protocols implementations (bsd, deflate, mppe). It looks like there is no easy way to get rid of that, so it was decided to leave it as is, but provide those cases with appropriate comments instead. Changes in v2: - Fix the order of checking skb data room and proto decompression - Remove "inline" keyword from ppp_decompress_proto() - Don't split line before function name - Prefix ppp_decompress_proto() function with "__" - Add ppp_decompress_proto() function with skb data room checks - Add description for introduced functions - Fix comments (as per review on mailing list) Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org> Reviewed-by: Guillaume Nault <g.nault@alphalink.fr> Signed-off-by: David S.

2018-12-20net: dsa: microchip: fix unicast frame leakTristram Ha1-4/+4
Port partitioning is done by enabling UNICAST_VLAN_BOUNDARY and changing the default port membership of 0x7f to other values such that there is no communication between ports. In KSZ9477 the member for port 1 is 0x41; port 2, 0x42; port 3, 0x44; port 4, 0x48; port 5, 0x50; and port 7, 0x60. Port 6 is the host port. Setting a zero value can be used to stop port from receiving. However, when UNICAST_VLAN_BOUNDARY is disabled and the unicast addresses are already learned in the dynamic MAC table, setting zero still allows devices connected to those ports to communicate. This does not apply to multicast and broadcast addresses though. To prevent these leaks and make the function of port membership consistent UNICAST_VLAN_BOUNDARY should never be disabled. Note that UNICAST_VLAN_BOUNDARY is enabled by default in KSZ9477.

2018-12-20mlxsw: spectrum: Switch to VID 4095 as default VIDIdo Schimmel3-21/+11
There is no need to abuse VID 1 anymore and we can instead use VID 4095 as the default VLAN, which will be configured on the port throughout its lifetime. The OVS join / leave functions are changed to enable VIDs 1-4094 (inclusive) instead of 2-4095. This because VID 4095 is now the default VLAN instead of 1.

2018-12-20mlxsw: spectrum: Add an helper function to cleanup VLAN entriesIdo Schimmel1-5/+10
VLAN entries on a port can be associated with either a bridge VLAN or a router port. Before the VLAN entry is destroyed these associations need to be cleaned up. Currently, this is always invoked from the function which destroys the VLAN entry, but next patch is going to skip the destruction of the default entry when a port in unlinked from a LAG. The above does not mean that the associations should not be cleaned up, so add a helper that will be invoked from both call sites.

2018-12-20mlxsw: spectrum: Allow controlling destruction of default port VLANIdo Schimmel1-4/+9
The function allows flushing all the existing VLAN entries on a port. It is invoked when a port is destroyed and when it is unlinked from a LAG. In the latter case, when moving to the new default VLAN, there will not be a need to destroy the default VLAN entry. Therefore, add an argument that allows to control whether the default port VLAN should be destroyed or not. Currently it is always set to 'true'.

Currently, the driver does not set the port's PVID when initializing a new port. This is because the driver is using VID 1 as PVID which is the firmware default. Subsequent patches are going to change the PVID the driver is setting when initializing a new port. Prepare for that by explicitly setting the port's PVID.

2018-12-20mlxsw: spectrum_router: Do not force specific configuration orderIdo Schimmel3-2/+24
In symmetric routing, the only two members in the VLAN corresponding to the L3 VNI are the router port and the VXLAN tunnel. In case the VXLAN device is already enslaved to the bridge and only later the VLAN interface is configured, the tunnel will not be offloaded. The reason for this is that when the router interface (RIF) corresponding to the VLAN interface is configured, it calls the core fid_get() API which does not check if NVE should be enabled on the FID. Instead, call into the bridge code which will check if NVE should be enabled on the FID. This effectively means that the same code path is used to retrieve a FID when either a local port or a router port joins the FID.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-12-20 This series contains updates to e100, igb, ixgbe, i40e and ice drivers. I replaced spinlocks for mutex locks to reduce the latency on CPU0 for igb when updating the statistics. This work was based off a patch provided by Jan Jablonsky, which was against an older version of the igb driver. Jesus adjusts the receive packet buffer size from 32K to 30K when running in QAV mode, to stay within 60K for total packet buffer size for igb. Vinicius adds igb kernel documentation regarding the CBS algorithm and its implementation in the i210 family of NICs. YueHaibing from Huawei fixed the e100 driver that was potentially passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL() instead. Konstantin Khorenko fixes i40e where we were not setting up the neigh_priv_len in our net_device, which caused the driver to read beyond the neighbor entry allocated memory. Miroslav Lichvar extends the PTP gettime() to read the system clock by adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e. Young Xiao fixed the ice driver to only enable NAPI on q_vectors that actually have transmit and receive rings. Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the NIC does not wake up when a cable is plugged in. This was due to the driver not setting PME during runtime suspend. Stephen Douthit enables the ixgbe driver allow DSA devices to use the MII interface to talk to switches. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Use the mii_bus callbacks to address the entire clause 22/45 address space. Enables userspace to poke switch registers instead of a single PHY address. The ixgbe firmware may be polling PHYs in a way that is not protected by the mii_bus lock. This isn't new behavior, but as Andrew Lunn pointed out there are more addresses available for conflicts.

2018-12-20igb: Fix an issue that PME is not enabled during runtime suspendKai-Heng Feng1-3/+5
I210 ethernet card doesn't wakeup when a cable gets plugged. It's because its PME is not set. Since commit 42eca2302146 ("PCI: Don't touch card regs after runtime suspend D3"), if the PCI state is saved, pci_pm_runtime_suspend() stops calling pci_finish_runtime_suspend(), which enables the PCI PME. To fix the issue, let's not to save PCI states when it's runtime suspend, to let the PCI subsystem enables PME.

Out of bound read reported by KASan. i40iw_net_event() reads unconditionally 16 bytes from neigh->primary_key while the memory allocated for "neighbour" struct is evaluated in neigh_alloc() as tbl->entry_size + dev->neigh_priv_len where "dev" is a net_device.
