2019-10-18net/mlx5e: kTLS, Fix page refcnt leak in TX resync error flowTariq Toukan
All references for frag pages that are obtained in tx_sync_info_get() should be released. Release usually occurs in the corresponding CQE of the WQE. In error flows, not all fragments have a WQE posted for them, hence no matching CQE will be generated. For these pages, release the reference in the error flow.

2019-10-18USB: ldusb: fix read info leaksJohan Hovold
Fix broken read implementation, which could be used to trigger slab info leaks. The driver failed to check if the custom ring buffer was still empty when waking up after having waited for more data. This would happen on every interrupt-in completion, even if no data had been added to the ring buffer (e.g. on disconnect events). Due to missing sanity checks and uninitialised (kmalloced) ring-buffer entries, this meant that huge slab info leaks could easily be triggered. Note that the empty-buffer check after wakeup is enough to fix the info leak on disconnect, but let's clear the buffer on allocation and add a sanity check to read() to prevent further leaks.

2019-10-18IB/core: Use rdma_read_gid_l2_fields to compare GID L2 fieldsParav Pandit
Current code tries to derive VLAN ID and compares it with GID attribute for matching entry. This raw search fails on macvlan netdevice as its not a VLAN device, but its an upper device of a VLAN netdevice. Due to this limitation, incoming QP1 packets fail to match in the GID table. Such packets are dropped. Hence, to support it, use the existing rdma_read_gid_l2_fields() that takes care of diffferent device types.

The AB8500 GPADC driver is indeed a "general purpose ADC" driver, and while the IIO subsystem did not exist when the driver was first merged, it is never too late to clean things up and move it to the right place. Nowadays IIO provides the right abstractions and interfaces to do generic ADC work in the kernel. We have to cut a bunch of debugfs luggage to make this transition swift, but all these files to is read out the raw values of the ADC and the IIO subsystem already has a standard sysfs ABI for doing exactly this: no debugfs is needed.

This is a new driver for the ST-Ericsson AB8500 GPADC, which replaces the old driver in drivers/mfd/ab8500-gpadc.c and thus gets rid of another necessarily different custom driver from the times before IIO existed. The AB8500 GPADC can convert 10 different channels and these are used for monitoring voltages in the U8500 chipset, some are used for battery charging, some for temperature monitoring. As this is very core functionality that a lot of drivers depend on and was formerly compiled in with the AB8500 core driver, we deafault it to 'y' in Kconfig: it can be compiled out but it is really not advisible: the platform can for example overheat if we do.

2019-10-18net: usb: lan78xx: Connect PHY before registering MACAndrew Lunn
As soon as the netdev is registers, the kernel can start using the interface. If the driver connects the MAC to the PHY after the netdev is registered, there is a race condition where the interface can be opened without having the PHY connected. Change the order to close this race condition.

2019-10-18Merge branch 'vsock-virtio-make-the-credit-mechanism-more-robust'David S. Miller
Stefano Garzarella says: ==================== vsock/virtio: make the credit mechanism more robust This series makes the credit mechanism implemented in the virtio-vsock devices more robust. Patch 1 sends an update to the remote peer when the buf_alloc change. Patch 2 prevents a malicious peer (especially the guest) can consume all the memory of the other peer, discarding packets when the credit available is not respected. ==================== Signed-off-by: David S.

2019-10-18vsock/virtio: discard packets if credit is not respectedStefano Garzarella
If the remote peer doesn't respect the credit information (buf_alloc, fwd_cnt), sending more data than it can send, we should drop the packets to prevent a malicious peer from using all of our memory. This is patch follows the VIRTIO spec: "VIRTIO_VSOCK_OP_RW data packets MUST only be transmitted when the peer has sufficient free buffer space for the payload" Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Signed-off-by: David S.

2019-10-18vsock/virtio: send a credit update when buffer size is changedStefano Garzarella
When the user application set a new buffer size value, we should update the remote peer about this change, since it uses this information to calculate the credit available. Signed-off-by: Stefano Garzarella <sgarzare@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-10-18mlxsw: spectrum_trap: Push Ethernet header before reporting trapIdo Schimmel
devlink maintains packets and bytes statistics for each trap. Since eth_type_trans() was called to set the skb's protocol, the data pointer no longer points to the start of the packet and the bytes accounting is off by 14 bytes. Fix this by pushing the skb's data pointer to the start of the packet.

2019-10-18ASoC: SOF: control: return true when kcontrol values changeDragos Tarcatu
All the kcontrol put() functions are currently returning 0 when successful. This does not go well with alsamixer as it does not seem to get notified on SND_CTL_EVENT_MASK_VALUE callbacks when values change for (some of) the sof kcontrols. This patch fixes that by returning true for volume, switch and enum type kcontrols when values do change in put().

2019-10-18ASoC: stm32: sai: fix sysclk management on shutdownOlivier Moysan
The commit below, adds a call to sysclk callback on shutdown. This introduces a regression in stm32 SAI driver, as some clock services are called twice, leading to unbalanced calls. Move processing related to mclk from shutdown to sysclk callback. When requested frequency is 0, assume shutdown and release mclk.
