2018-06-01net: hns3: Add missing break in misc_irq_handleYunsheng Lin
There is a break missing in the switch/case handling in hclge_misc_irq_handle, which causes the log to output uncorrectly. This patch adds the missing break, and change the dev_dbg to dev_warn in order to better catch the error.

2018-06-01net: hns3: Fix for phy not link up problem after resettingYunsheng Lin
When resetting, phy_state_machine may be accessing the phy through firmware if the phy is not stopped or disconnected, which will cause firemware timeout problem because the firmware is busy processing the reset request. This patch fixes it by disabling the phy when resetting.

2018-06-01net: hns3: Fix for hclge_reset running repeatly problemYunsheng Lin
When hardware sends the HCLGE_VECTOR0_EVENT_RST event through hclge_misc_irq_handle, currently driver enables misc_vector in the interrupt handle, and hardware generates the same interrupt for the same reset event again and again until the reset is complete, which causes hclge_reset running repeatly problem. This patch fixes by enabling the misc_vector after reset is complete.

2018-06-01net: hns3: Fix for service_task not running problem after resettingYunsheng Lin
When hclge_ae_stop is called during resetting, it will cancel the service_task by calling cancel_work_sync, which may cause the service_task to exit without clearing HCLGE_STATE_SERVICE_SCHED bit. If this happens, the service_task will never run again. This patch fixes this problem by clearing it after calling cancel_work_sync in hclge_ae_stop.

Petr Machata says: ==================== Test mirror-to-gretap with bridge in UL This patchset adds more tests to the mirror-to-gretap suite where bridge is present in the underlay. Specifically it adds tests for bridge VLAN handling, FDB, and bridge port STP status. In patches #1-#3, the codebase is refactored to support the new tests. In patch #4, an STP test is added to the mirroring library, that will later be called from bridge tests. In patches #5-#8, the test for mirror-to-gretap with an 802.1q bridge in underlay is adapted and more tests are added. In patch #9, an STP test is added to the test suite for mirror-to-gretap with an 802.1d bridge in underlay. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2018-06-01xprtrdma: Wait on empty sendctx queueChuck Lever
Currently, when the sendctx queue is exhausted during marshaling, the RPC/RDMA transport places the RPC task on the delayq, which forces a wait for HZ >> 2 before the marshal and send is retried. With this change, the transport now places such an RPC task on the pending queue, and wakes it just as soon as more sendctxs become available. This typically takes less than a millisecond, and the write_space waking mechanism is less deadlock-prone. Moreover, the waiting RPC task is holding the transport's write lock, which blocks the transport from sending RPCs. Therefore faster recovery from sendctx queue exhaustion is desirable.

2018-06-01ip_tunnel: restore binding to ifaces with a large mtuNicolas Dichtel
After commit f6cc9c054e77, the following conf is broken (note that the default loopback mtu is 65536, ie IP_MAX_MTU + 1): $ ip tunnel add gre1 mode gre local 10.125.0.1 remote 10.125.0.2 dev lo add tunnel "gre0" failed: Invalid argument $ ip l a type dummy $ ip l s dummy1 up $ ip l s dummy1 mtu 65535 $ ip tunnel add gre1 mode gre local 10.125.0.1 remote 10.125.0.2 dev dummy1 add tunnel "gre0" failed: Invalid argument dev_set_mtu() doesn't allow to set a mtu which is too large. First, let's cap the mtu returned by ip_tunnel_bind_dev(). Second, remove the magic value 0xFFF8 and use IP_MAX_MTU instead. 0xFFF8 seems to be there for ages, I don't know why this value was used. With a recent kernel, it's also possible to set a mtu > IP_MAX_MTU: $ ip l s dummy1 mtu 66000 After that patch, it's also possible to bind an ip tunnel on that kind of interface.

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. This cleans up the error handling a lot, as this code will never get hit.

2018-06-01kvm: Make VM ioctl do valloc for some archsMarc Orr
The kvm struct has been bloating. For example, it's tens of kilo-bytes for x86, which turns out to be a large amount of memory to allocate contiguously via kzalloc. Thus, this patch does the following: 1. Uses architecture-specific routines to allocate the kvm struct via vzalloc for x86. 2. Switches arm to __KVM_HAVE_ARCH_VM_ALLOC so that it can use vzalloc when has_vhe() is true. Other architectures continue to default to kalloc, as they have a dependency on kalloc or have a small-enough struct kvm.

2018-06-01kvm: Change return type to vm_fault_tSouptick Joarder
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. commit 1c8f422059ae ("mm: change return type to vm_fault_t") Signed-off-by: Souptick Joarder <jrdr.linux@gmail.com> Reviewed-by: Matthew Wilcox <mawilcox@microsoft.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
