2017-04-24mmc: meson-gx: remove unused members irq, ocr_mask from struct meson_hostHeiner Kallweit
Member ocr_mask is never used and member irq we can replace with a local variable in meson_mmc_probe. So let's remove both members.

2017-04-24dm verity: switch to using asynchronous hash crypto APIGilad Ben-Yossef
Use of the synchronous digest API limits dm-verity to using pure CPU based algorithm providers and rules out the use of off CPU algorithm providers which are normally asynchronous by nature, potentially freeing CPU cycles. This can reduce performance per Watt in situations such as during boot time when a lot of concurrent file accesses are made to the protected volume.

2017-04-24dm mpath: requeue after a small delay if blk_get_request() failsBart Van Assche
If blk_get_request() returns ENODEV then multipath_clone_and_map() causes a request to be requeued immediately. This can cause a kworker thread to spend 100% of the CPU time of a single core in __blk_mq_run_hw_queue() and also can cause device removal to never finish. Avoid this by only requeuing after a delay if blk_get_request() fails. Additionally, reduce the requeue delay.

Jakub Kicinski says: ==================== nfp: DMA flags, adjust head and fixes This series takes advantage of Alex's DMA_ATTR_SKIP_CPU_SYNC to make XDP packet modifications "correct" from DMA API point of view. It also allows us to parse the metadata before we run XDP at no additional DMA sync cost. That way we can get rid of the metadata memcpy, and remove the last upstream user of bpf_prog->xdp_adjust_head. David's patch adds a way to read capabilities from the management firmware. There are also two net-next fixes. Patch 4 which fixes what seems to be a result of a botched rebase on my part.

2017-04-24net/tcp_fastopen: Remove mss check in tcp_write_timeout()Wei Wang
Christoph Paasch from Apple found another firewall issue for TFO: After successful 3WHS using TFO, server and client starts to exchange data. Afterwards, a 10s idle time occurs on this connection. After that, firewall starts to drop every packet on this connection. The fix for this issue is to extend existing firewall blackhole detection logic in tcp_write_timeout() by removing the mss check.

2017-04-24net/tcp_fastopen: Disable active side TFO in certain scenariosWei Wang
Middlebox firewall issues can potentially cause server's data being blackholed after a successful 3WHS using TFO. Following are the related reports from Apple: https://www.nanog.org/sites/default/files/Paasch_Network_Support.pdf Slide 31 identifies an issue where the client ACK to the server's data sent during a TFO'd handshake is dropped. C ---> syn-data ---> S C <--- syn/ack ----- S C (accept & write) C <---- data ------- S C ----- ACK -> X S [retry and timeout] https://www.ietf.org/proceedings/94/slides/slides-94-tcpm-13.pdf Slide 5 shows a similar situation that the server's data gets dropped after 3WHS. C ---- syn-data ---> S C <--- syn/ack ----- S C ---- ack --------> S S (accept & write) C? X <- data ------ S [retry and timeout] This is the worst failure b/c the client can not detect such behavior to mitigate the situation (such as disabling TFO). Failing to proceed, the application (e.g., SSL library) may simply timeout and retry with TFO again, and the process repeats indefinitely. The proposed solution is to disable active TFO globally under the following circumstances: 1. client side TFO socket detects out of order FIN 2. client side TFO socket receives out of order RST We disable active side TFO globally for 1hr at first. Then if it happens again, we disable it for 2h, then 4h, 8h, ... And we reset the timeout to 1hr if a client side TFO sockets not opened on loopback has successfully received data segs from server. And we examine this condition during close(). The rational behind it is that when such firewall issue happens, application running on the client should eventually close the socket as it is not able to get the data it is expecting. Or application running on the server should close the socket as it is not able to receive any response from client. In both cases, out of order FIN or RST will get received on the client given that the firewall will not block them as no data are in those frames. And we want to disable active TFO globally as it helps if the middle box is very close to the client and most of the connections are likely to fail. Also, add a debug sysctl: tcp_fastopen_blackhole_detect_timeout_sec: the initial timeout to use when firewall blackhole issue happens. This can be set and read. When setting it to 0, it means to disable the active disable logic.

2017-04-24bnxt_en: Fix VF attributes reporting.Michael Chan
The .ndo_get_vf_config() is returning the wrong qos attribute. Fix the code that checks and reports the qos and spoofchk attributes. The BNXT_VF_QOS and BNXT_VF_LINK_UP flags should not be set by default during init. time. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-24bnxt_en: Pass DCB RoCE app priority to firmware.Michael Chan
When the driver gets the RoCE app priority set/delete call through DCBNL, the driver will send the information to the firmware to set up the priority VLAN tag for RDMA traffic.

2017-04-24openvswitch: Add eventmask support to CT action.Jarno Rajahalme
Add a new optional conntrack action attribute OVS_CT_ATTR_EVENTMASK, which can be used in conjunction with the commit flag (OVS_CT_ATTR_COMMIT) to set the mask of bits specifying which conntrack events (IPCT_*) should be delivered via the Netfilter netlink multicast groups. Default behavior depends on the system configuration, but typically a lot of events are delivered. This can be very chatty for the NFNLGRP_CONNTRACK_UPDATE group, even if only some types of events are of interest. Netfilter core init_conntrack() adds the event cache extension, so we only need to set the ctmask value. However, if the system is configured without support for events, the setting will be skipped due to extension not being found.

2017-04-24udp: disable inner UDP checksum offloads in IPsec caseAnsis Atteka
Otherwise, UDP checksum offloads could corrupt ESP packets by attempting to calculate UDP checksum when this inner UDP packet is already protected by IPsec. One way to reproduce this bug is to have a VM with virtio_net driver (UFO set to ON in the guest VM); and then encapsulate all guest's Ethernet frames in Geneve; and then further encrypt Geneve with IPsec. In this case following symptoms are observed: 1. If using ixgbe NIC, then it will complain with following error message: ixgbe 0000:01:00.1: partial checksum but l4 proto=32! 2. Receiving IPsec stack will drop all the corrupted ESP packets and increase XfrmInStateProtoError counter in /proc/net/xfrm_stat. 3. iperf UDP test from the VM with packet sizes above MTU will not work at all. 4. iperf TCP test from the VM will get ridiculously low performance because.

2017-04-24ASoC: bytcr_rt5640: Allow quirk set via module optionTakashi Iwai
The bytcr-rt5640 driver has a few quirk setups depending on the board, where the quirk value is set by DMI matching. When you have a new device to add the support, you often experience to try the different quirk by trial-and-error. Or, you may have a development model that still has no proper DMI string. In either case, you'd need to compile the driver at each time. This patch introduces a module option to override the quirk value on the fly. User can boot like snd-soc-sst-bytcr-rt5640.quirk=0x4004 to override the default value without recompilation. It's a raw value, so user needs to check the source code for the meaning of each bit.

2017-04-24ASoC: Call snd_soc_set_dmi_name() unconditionallyTakashi Iwai
Since recently UCM can pick up a configuration specific to the board via card longname field, and we introduced a helper function snd_soc_set_dmi_name() for that. So far, it was used only in one place (sound/soc/intel/boards/broadwell.c), but it should be more widely applied. This patch puts a big hammer for that: it lets snd_soc_register_card() calling snd_soc_set_dmi_name() unconditionally, so that all x86 devices get the better longname string. This would have no impact for other systems without DMI support, as snd_soc_set_dmi_name() is no-op on them.
