Fun set of conflict resolutions here... For the mac80211 stuff, these were fortunately just parallel adds. Trivially resolved. In drivers/net/phy/phy.c we had a bug fix in 'net' that moved the function phy_disable_interrupts() earlier in the file, whilst in 'net-next' the phy_error() call from this function was removed. In net/ipv4/xfrm4_policy.c, David Ahern's changes to remove the 'rt_table_id' member of rtable collided with a bug fix in 'net' that added a new struct member "rt_mtu_locked" which needs to be copied over here. The mlxsw driver conflict consisted of net-next separating the span code and definitions into separate files, whilst a 'net' bug fix made some changes to that moved code. The mlx5 infiniband conflict resolution was quite non-trivial, the RDMA tree's merge commit was used as a guide here, and here are their notes: ==================== Due to bug fixes found by the syzkaller bot and taken into the for-rc branch after development for the 4.17 merge window had already started being taken into the for-next branch, there were fairly non-trivial merge issues that would need to be resolved between the for-rc branch and the for-next branch. This merge resolves those conflicts and provides a unified base upon which ongoing development for 4.17 can be based. Conflicts: drivers/infiniband/hw/mlx5/main.c - Commit 42cea83f9524 (IB/mlx5: Fix cleanup order on unload) added to for-rc and commit b5ca15ad7e61 (IB/mlx5: Add proper representors support) add as part of the devel cycle both needed to modify the init/de-init functions used by mlx5. To support the new representors, the new functions added by the cleanup patch needed to be made non-static, and the init/de-init list added by the representors patch needed to be modified to match the init/de-init list changes made by the cleanup patch. Updates: drivers/infiniband/hw/mlx5/mlx5_ib.h - Update function prototypes added by representors patch to reflect new function names as changed by cleanup patch drivers/infiniband/hw/mlx5/ib_rep.c - Update init/de-init stage list to match new order from cleanup patch ==================== Signed-off-by: David S.

These have appeared in a linux-next release and have a build success report from the 0day robot. * The 4.16 rework of altmap handling led to some configurations leaking page table allocations due to freeing from the altmap reservation rather than the page allocator. The impact without the fix is leaked memory and a WARN() message when tearing down libnvdimm namespaces. The rework also missed a place where error handling code needed to be removed that can lead to a crash if devm_memremap_pages() fails. * acpi_map_pxm_to_node() had a latent bug whereby it could misidentify the closest online node to a given proximity domain. * Block integrity handling was reworked several kernels back to allow calling add_disk() after setting up the integrity profile. The nd_btt and nd_blk drivers are just now catching up to fix automatic partition detection at driver load time. * The new peristence_domain attribute, a platform indicator of whether cpu caches are powerfail protected for example, is meant to be a single value enum and not a set of flags.

2018-03-22net: hns3: Changes required in PF mailbox to support VF resetSalil Mehta3-1/+44
PF needs to assert the VF reset when it receives the request to reset from VF. After receiving request PF ackknowledges the request by replying back MBX_ASSERTING_RESET message to VF. VF then goes to pending state and wait for hardware to complete the reset. This patch contains code to handle the received VF message, inform the VF of assertion and reset the VF using cmdq interface.

2018-03-22net: hns3: Add *Asserting Reset* mailbox message & handling in VFSalil Mehta2-0/+13
Reset Asserting message is forwarded by PF to inform VF about the hardware reset which is about to happen. This might be due to the earlier VF reset request received by the PF or because PF for any reason decides to undergo reset. This message results in VF to go in pending state in which it polls the hardware to complete the reset and then further resets/tears its own stack.

2018-03-22net: hns3: Changes to support ARQ(Asynchronous Receive Queue)Salil Mehta5-14/+111
Current mailbox CRQ could consists of both synchronous and async responses from the PF. Synchronous responses are time critical and should be handed over to the waiting tasks/context as quickly as possible otherwise timeout occurs. Above problem gets accentuated if CRQ consists of even single async message. Hence, it is important to have quick handling of synchronous messages and maybe deferred handling of async messages This patch introduces separate ARQ(async receive queues) for the async messages. These messages are processed later with repsect to mailbox task while synchronous messages still gets processed in context to mailbox interrupt. ARQ is important as VF reset introduces some new async messages like MBX_ASSERTING_RESET which adds up to the presssure on the responses for synchronousmessages and they timeout even more quickly.

2018-03-22net: hns3: Add support to re-initialize the hclge deviceSalil Mehta2-14/+106

2018-03-22net: hns3: Add VF Reset device state and its handlingSalil Mehta3-5/+68
This introduces the hclge device reset states of "requested" and "pending" and also its handling in context to Reset Service Task. Device gets into requested state because of any VF reset request asserted from upper layers, for example due to watchdog timeout expiration. Requested state would result in eventually forwarding the VF reset request to PF which would actually reset the VF. Device will get into pending state if: 1. VF receives the acknowledgement from PF for the VF reset request it originally sent to PF. 2. Reset Service Task detects that after asserting VF reset for certain times the data-path is not working and device then decides to assert full VF reset(this means also resetting the PCIe interface). 3. PF intimates the VF that it has undergone reset. Pending state would result in VF to poll for hardware reset completion status and then resetting the stack/enet layer, which in turn means reinitializing the ring management/enet layer. Note: we would be adding support of 3. later as a separate patch. This decision should not affect VF reset as its event handling is generic in nature.

PF already supports reset functionality to handle the network stack watchdog timeout trigger but the existing code is not generic enough to be used to support VF reset as well. This patch does following: 1. Makes the existing watchdog timeout handler in enet layer generic i.e. suitable for both VF and PF and 2. Introduces the new reset event handler for the VF code. 3.

2018-03-22net: hns3: export pci table of hclge and hclgevf to userspaceYunsheng Lin2-0/+4
There is no module that is dependent on hclge or hclgevf's symbol, but hns_enet need them to provide ops for it to run. When there is a need to auto load the hns3 driver, the auto load will fail because hclge or hclgevf is not loaded. Hns_enet has already exported the pci table, so this patch exports the pci table for hclge and hclgevf module too.

VF queue reset flow is different from PF queue reset flow. VF driver should stop VF queue first, then send message to PF and PF do the reset.

2018-03-22net: hns3: reallocate tx/rx buffer after changing mtuFuyun Liang1-14/+22
When changing the mtu, the max frame size also will be changed. The tx buffer size and the rx buffer size to be allocated are determined by max frame size. So when max frame size is changed, the tx buffer and rx buffer need to be reallocated. When the tc_num is changed, the tx buffer and rx buffer need to be reallocated too. So calling set_mtu and buffer_alloc separately is better. Signed-off-by: Fuyun Liang <liangfuyun1@huawei.com> Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: David S.

We have a functional dependency on the FIXED_PHY MDIO bus because we register fixed PHY devices "the old way" which only works if the code that does this has had a chance to run before the fixed MDIO bus is probed. Make sure we account for that and have dsa_loop_bdinfo.o be either built-in or modular depending on whether CONFIG_FIXED_PHY reflects that too.

Make common function for detaching internals of device during changes to MTU and RSS. Make sure no more packets are transmitted and all packets have been received before doing device teardown. Change the wait logic to be common and use usleep_range(). Changes transmit enabling logic so that transmit queues are disabled during the period when lower device is being changed. And enabled only after sub channels are setup. This avoids issue where it could be that a packet was being sent while subchannel was not initialized.

2018-03-22ppp: avoid loop in xmit recursion detection codeGuillaume Nault1-12/+14
We already detect situations where a PPP channel sends packets back to its upper PPP device. While this is enough to avoid deadlocking on xmit locks, this doesn't prevent packets from looping between the channel and the unit. The problem is that ppp_start_xmit() enqueues packets in ppp->file.xq before checking for xmit recursion. Therefore, __ppp_xmit_process() might dequeue a packet from ppp->file.xq and send it on the channel which, in turn, loops it back on the unit. Then ppp_start_xmit() queues the packet back to ppp->file.xq and __ppp_xmit_process() picks it up and sends it again through the channel. Therefore, the packet will loop between __ppp_xmit_process() and ppp_start_xmit() until some other part of the xmit path drops it. For L2TP, we rapidly fill the skb's headroom and pppol2tp_xmit() drops the packet after a few iterations. But PPTP reallocates the headroom if necessary, letting the loop run and exhaust the machine resources (as reported in https://bugzilla.kernel.org/show_bug.cgi?id=199109). Fix this by letting __ppp_xmit_process() enqueue the skb to ppp->file.xq, so that we can check for recursion before adding it to the queue. Now ppp_xmit_process() can drop the packet when recursion is detected. __ppp_channel_push() is a bit special. It calls __ppp_xmit_process() without having any actual packet to send. This is used by ppp_output_wakeup() to re-enable transmission on the parent unit (for implementations like ppp_async.c, where the .start_xmit() function might not consume the skb, leaving it in ppp->xmit_pending and disabling transmission). Therefore, __ppp_xmit_process() needs to handle the case where skb is NULL, dequeuing as many packets as possible from ppp->file.xq.
