2017-04-25usb: Make sure usb/phy/of gets built-inAlexey Brodkin
DWC3 driver uses of_usb_get_phy_mode() which is implemented in drivers/usb/phy/of.c and in bare minimal configuration it might not be pulled in kernel binary.

2017-04-25bridge: move bridge multicast cleanup to ndo_uninitXin Long
During removing a bridge device, if the bridge is still up, a new mdb entry still can be added in br_multicast_add_group() after all mdb entries are removed in br_multicast_dev_del(). Like the path: mld_ifc_timer_expire -> mld_sendpack -> ... br_multicast_rcv -> br_multicast_add_group The new mp's timer will be set up. If the timer expires after the bridge is freed, it may cause use-after-free panic in br_multicast_group_expired.

With Nikolay's suggestion, this patch is to clean up bridge multicast in ndo_uninit after bridge dev is shutdown, instead of br_dev_delete, so that netif_running check in br_multicast_add_group can avoid this issue. v1->v2: - fix this issue by moving br_multicast_dev_del to ndo_uninit, instead of calling dev_close in br_dev_delete.

2017-04-25lpfc: Fix memory corruption of the lpfc_ncmd->list pointersJames Smart
lpfc was changing the private pointer that is set/maintained by the nvme_fc transport. This caused two issues: a) the transport, on teardown may erroneous attempt to free whatever address was set; and b) lfpc uses any value set in lpfc_nvme_fcp_abort() and assumes its a valid io request. Correct issue by properly defining a context structure for lpfc. Lpfc also updated to clear the private context structure on io completion. Since this bug caused scrutiny of the way lpfc moves local request structures between lists, also cleaned up list_del()'s to list_del_inits()'s. This is a nvme-specific bug. The patch was cut against the linux-block tree, for-4.12/block tree. It should be pulled in through that tree.

2017-04-25ipv6: fix source routingSabrina Dubroca
Commit a149e7c7ce81 ("ipv6: sr: add support for SRH injection through setsockopt") introduced handling of IPV6_SRCRT_TYPE_4, but at the same time restricted it to only IPV6_SRCRT_TYPE_0 and IPV6_SRCRT_TYPE_4. Previously, ipv6_push_exthdr() and fl6_update_dst() would also handle other values (ie STRICT and TYPE_2). Restore previous source routing behavior, by handling IPV6_SRCRT_STRICT and IPV6_SRCRT_TYPE_2 the same way as IPV6_SRCRT_TYPE_0 in ipv6_push_exthdr() and fl6_update_dst().

2017-04-25net: Generic XDPDavid S. Miller
This provides a generic SKB based non-optimized XDP path which is used if either the driver lacks a specific XDP implementation, or the user requests it via a new IFLA_XDP_FLAGS value named XDP_FLAGS_SKB_MODE. It is arguable that perhaps I should have required something like this as part of the initial XDP feature merge. I believe this is critical for two reasons: 1) Accessibility. More people can play with XDP with less dependencies. Yes I know we have XDP support in virtio_net, but that just creates another depedency for learning how to use this facility. I wrote this to make life easier for the XDP newbies. 2) As a model for what the expected semantics are. If there is a pure generic core implementation, it serves as a semantic example for driver folks adding XDP support. One thing I have not tried to address here is the issue of XDP_PACKET_HEADROOM, thanks to Daniel for spotting that. It seems incredibly expensive to do a skb_cow(skb, XDP_PACKET_HEADROOM) or whatever even if the XDP program doesn't try to push headers at all. I think we really need the verifier to somehow propagate whether certain XDP helpers are used or not. v5: - Handle both negative and positive offset after running prog - Fix mac length in XDP_TX case (Alexei) - Use rcu_dereference_protected() in free_netdev (kbuild test robot) v4: - Fix MAC header adjustmnet before calling prog (David Ahern) - Disable LRO when generic XDP is installed (Michael Chan) - Bypass qdisc et al. on XDP_TX and record the event (Alexei) - Do not perform generic XDP on reinjected packets (DaveM) v3: - Make sure XDP program sees packet at MAC header, push back MAC header if we do XDP_TX. (Alexei) - Elide GRO when generic XDP is in use. (Alexei) - Add XDP_FLAG_SKB_MODE flag which the user can use to request generic XDP even if the driver has an XDP implementation. (Alexei) - Report whether SKB mode is in use in rtnl_xdp_fill() via XDP_FLAGS attribute. (Daniel) v2: - Add some "fall through" comments in switch statements based upon feedback from Andrew Lunn - Use RCU for generic xdp_prog, thanks to Johannes Berg.

2017-04-25scsi: sd_zbc: Do not write lock zones for resetDamien Le Moal
Resetting a zone write pointer is equivalent to discarding sectors: after a reset, the zone sectors will contain zeros (or the format pattern). So there is no need for mutual exclusion between a zone reset and write. Similarly to discard, make it the responsability of the user to properly synchronize between reset and write (as is done now for discard and write).

2017-04-25qed - VF tunnelling support [VXLAN/GENEVE/GRE]Chopra, Manish
This patch adds hardware channel APIs support between VF and PF for tunnelling configuration for the VFs. According to that configuration VFs can run VXLAN/GENEVE/GRE tunnels over it with tunnel features offloaded. Using these APIs VF can also request for UDP ports configuration to the PF, although PF and it's child VFs share the same port.

2017-04-25tipc: fix socket flow control accounting error at tipc_recv_streamParthasarathy Bhuvaragan
Until now in tipc_recv_stream(), we update the received unacknowledged bytes based on a stack variable and not based on the actual message size. If the user buffer passed at tipc_recv_stream() is smaller than the received skb, the size variable in stack differs from the actual message size in the skb. This leads to a flow control accounting error causing permanent congestion. In this commit, we fix this accounting error by always using the size of the incoming message.

2017-04-25tipc: fix socket flow control accounting error at tipc_send_streamParthasarathy Bhuvaragan
Until now in tipc_send_stream(), we return -1 when the socket encounters link congestion even if the socket had successfully sent partial data. This is incorrect as the application resends the same the partial data leading to data corruption at receiver's end. In this commit, we return the partially sent bytes as the return value at link congestion.

2017-04-25ipv6: move stub initialization after ipv6 setup completionPaolo Abeni
The ipv6 stub pointer is currently initialized before the ipv6 routing subsystem: a 3rd party can access and use such stub before the routing data is ready. Moreover, such pointer is not cleared in case of initialization error, possibly leading to dangling pointers usage. This change addresses the above moving the stub initialization at the end of ipv6 init code.
