Pull NVMe fixes from Christoph: "Three more fixes for 4.13 below: - fix the incorrect bit for the doorbell buffer features (Changpeng Liu) - always use a 4k MR page size for RDMA, to not get in trouble with offset in non-4k page size systems (no-op for x86) (Max Gurtovoy) - and a fix for the new nvme host memory buffer support to keep the descriptor list DMA mapped when the buffer is enabled (me)"
2017-08-30ALSA: pcm: Fix power lock unbalance via OSS emulationTakashi Iwai
PCM OSS emulation issues the drain ioctl without power lock. It used to work in the earlier kernels as the power lock was taken inside snd_pcm_drain() itself. But since 68b4acd32249 ("ALSA: pcm: Apply power lock globally to common ioctls"), the power lock is taken outside the function. Due to that change, the call via OSS emulation leads to the unbalanced power lock, thus it deadlocks. As a quick fix, just take the power lock before snd_pcm_drain() call for OSS emulation path. A better cleanup will follow later.

2017-08-30nvme-pci: use dma memory for the host memory buffer descriptorsChristoph Hellwig
The NVMe 1.3 specification says in section 5.21.1.13: "After a successful completion of a Set Features enabling the host memory buffer, the host shall not write to the associated host memory region, buffer size, or descriptor list until the host memory buffer has been disabled." While this doesn't state that the descriptor list must remain accessible to the device it certainly implies it must remaing readable by the device. So switch to a dma coherent allocation for the descriptor list just to be safe - it's not like the cost for it matters compared to the actual memory buffers.

2017-08-30iwlwifi: mvm: Avoid deferring non bufferable framesDavid Spinadel
Use bcast station for all non bufferable frames on AP and AD-HOC. The host is no longer aware of STAs PS status because of buffer station offload, so we can't rely on mac80211 to toggle on IEEE80211_TX_CTL_NO_PS_BUFFER bit. A possible issue with buffering such frames, beside the obvious spec violation, is when a station disconnects while in PS but the AP isn't aware of that. In such scenarios the AP won't be able to send probe responses or auth frames so the STA won't be able to reconnect and the AP will have a queue hang.

2017-08-29neigh: increase queue_len_bytes to match wmem_defaultEric Dumazet
Florian reported UDP xmit drops that could be root caused to the too small neigh limit. Current limit is 64 KB, meaning that even a single UDP socket would hit it, since its default sk_sndbuf comes from net.core.wmem_default (~212992 bytes on 64bit arches). Once ARP/ND resolution is in progress, we should allow a little more packets to be queued, at least for one producer. Once neigh arp_queue is filled, a rogue socket should hit its sk_sndbuf limit and either block in sendmsg() or return -EAGAIN.

2017-08-29amd-xgbe: Interrupt summary bits are h/w version dependentTom Lendacky
There is a difference in the bit position of the normal interrupt summary enable (NIE) and abnormal interrupt summary enable (AIE) between revisions of the hardware. For older revisions the NIE and AIE bits are positions 16 and 15 respectively. For newer revisions the NIE and AIE bits are positions 15 and 14. The effect in changing the bit position is that newer hardware won't receive AIE interrupts in the current version of the driver. Specifically, the driver uses this interrupt to collect statistics on when a receive buffer unavailable event occurs and to restart the driver/device when a fatal bus error occurs. Update the driver to set the interrupt enable bit based on the reported version of the hardware. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.

Jiri Benc says: ==================== nsh: headers, GSO This adds header structs and helpers for NSH together with GSO support. Note there is no code in this patchset that actually manipulates the NSH headers. That was sent to netdev by Yi Yang ("[PATCH net-next v6 0/3] openvswitch: add NSH support"). The aim of this series is to lay the groundwork and ease the implementation for him. In addition to openvswitch, the NSH support should be added to tc (flower to match, act_nsh to push/pop NSH headers). That will come later. There's currently no plan to support NSH by other means than those two. The patch 3 in this patchset was written by Yi Yang, I took it from the aforementioned series and slightly modified it - see the note in the patch. ==================== Signed-off-by: David S.

Hopefully they'll get a single IANA registry for the values, too. (I asked them for that.) Factor out the code to be shared by the NSH implementation. NSH and MPLS values are added in this patch, too. For MPLS, the drafts incorrectly assign only a single value, while we have two MPLS ethertypes. I raised the problem with both groups.

RSB_SWAP0 needs to match the host CPU endian, and it needs to be set for LE and clear for BE. RSB_SWAP1 must always be cleared for SYSTEMPORT Lite. With these settings, we have the Receive Status Block always match the host endian and we do not need to perform any conversion. Since there is not necessarily a CONFIG_CPU_LITTLE_ENDIAN option defined, we test for !CONFIG_CPU_BIG_ENDIAN which is guaranteed to be set.
