2021-12-22net/mlx5e: Fix interoperability between XSK and ICOSQ recovery flowMaxim Mikityanskiy5-4/+58
Both regular RQ and XSKRQ use the same ICOSQ for UMRs. When doing recovery for the ICOSQ, don't forget to deactivate XSKRQ. XSK can be opened and closed while channels are active, so a new mutex prevents the ICOSQ recovery from running at the same time. The ICOSQ recovery deactivates and reactivates XSKRQ, so any parallel change in XSK state would break consistency. As the regular RQ is running, it's not enough to just flush the recovery work, because it can be rescheduled.

2021-12-22net/mlx5e: Fix skb memory leak when TC classifier action offloads are disabledGal Pressman1-1/+1
When TC classifier action offloads are disabled (CONFIG_MLX5_CLS_ACT in Kconfig), the mlx5e_rep_tc_receive() function which is responsible for passing the skb to the stack (or freeing it) is defined as a nop, and results in leaking the skb memory. Replace the nop with a call to napi_gro_receive() to resolve the leak.

2021-12-22scsi: vmw_pvscsi: Set residual data length conditionallyAlexey Makhalov1-2/+5
The PVSCSI implementation in the VMware hypervisor under specific configuration ("SCSI Bus Sharing" set to "Physical") returns zero dataLen in the completion descriptor for READ CAPACITY(16). As a result, the kernel can not detect proper disk geometry. This can be recognized by the kernel message: [ 0.776588] sd 1:0:0:0: [sdb] Sector size 0 reported, assuming 512. The PVSCSI implementation in QEMU does not set dataLen at all, keeping it zeroed. This leads to a boot hang as was reported by Shmulik Ladkani. It is likely that the controller returns the garbage at the end of the buffer. Residual length should be set by the driver in that case. The SCSI layer will erase corresponding data. See commit bdb2b8cab439 ("[SCSI] erase invalid data returned by device") for details. Commit e662502b3a78 ("scsi: vmw_pvscsi: Set correct residual data length") introduced the issue by setting residual length unconditionally, causing the SCSI layer to erase the useful payload beyond dataLen when this value is returned as 0. As a result, considering existing issues in implementations of PVSCSI controllers, we do not want to call scsi_set_resid() when dataLen == 0. Calling scsi_set_resid() has no effect if dataLen equals buffer length.

The completer in the "or,ev %r1,%r30,%r30" instruction is reversed, so we are not clipping the LWS number when we are called from a 32-bit process (W=0). We need to nulify the following depdi instruction when the least-significant bit of %r30 is 1. If the %r20 register is not clipped, a user process could perform a LWS call that would branch to an undefined location in the kernel and potentially crash the machine.

2021-12-21KVM: VMX: Wake vCPU when delivering posted IRQ even if vCPU == this vCPUSean Christopherson1-2/+1
Drop a check that guards triggering a posted interrupt on the currently running vCPU, and more importantly guards waking the target vCPU if triggering a posted interrupt fails because the vCPU isn't IN_GUEST_MODE. If a vIRQ is delivered from asynchronous context, the target vCPU can be the currently running vCPU and can also be blocking, in which case skipping kvm_vcpu_wake_up() is effectively dropping what is supposed to be a wake event for the vCPU. The "do nothing" logic when "vcpu == running_vcpu" mostly works only because the majority of calls to ->deliver_posted_interrupt(), especially when using posted interrupts, come from synchronous KVM context. But if a device is exposed to the guest using vfio-pci passthrough, the VFIO IRQ and vCPU are bound to the same pCPU, and the IRQ is _not_ configured to use posted interrupts, wake events from the device will be delivered to KVM from IRQ context, e.g. vfio_msihandler() | |-> eventfd_signal() | |-> ... | |-> irqfd_wakeup() | |->kvm_arch_set_irq_inatomic() | |-> kvm_irq_delivery_to_apic_fast() | |-> kvm_apic_set_irq() This also aligns the non-nested and nested usage of triggering posted interrupts, and will allow for additional cleanups.
