Bug Description:

A bug in the vfio_pci driver was reported in junction with work on FPGA
cards. We were able to reproduce and root-cause the bug using system-tap.
The original bug description is below. An understanding of the referenced
dfl and opae tools is not required - it is the sequence of IOCTL calls and
IRQ vectors that matters:

> I’m trying to get an example AFU working that uses 2 IRQs, active at the same
> time. I’m hitting what looks to be a dfl_pci driver bug.
>
> The code tries to allocate two IRQ vectors: 0 and 1. I see opaevfio.c doing the
> right thing, picking the MSIX index. Allocating either IRQ 0 or IRQ 1 works fine
> and I confirm that the VFIO_DEVICE_SET_IRQS looks reasonable, choosing MSIX and
> either start of 0 or 1 and count 1.
>
> Note that opaevfio.c always passes count 1, so it will make separate calls for
> each IRQ vector.
>
> When I try to allocate both, I see the following:
>
> * If the VFIO_DEVICE_SET_IRQS ioctl is called first with start 0 and then
> start 1 (always count 1), the start 1 (second) ioctl trap returns EINVAL.
> * If I set up the vectors in decreasing order, so start 1 followed by start 0,
> the program works!
> * I ruled out OPAE SDK user space problems by setting up my program to
> allocate in increasing order, which would normally fail. I changed only the
> ioctl call in user space opaevfio.c, inverting bit 0 of start so that the
> driver is called in decreasing index order. Of course this binds the wrong
> vectors to the fds, but I don’t care about that for now. This works! From
> this, I conclude that it can’t be a user space problem since the difference
> between working and failing is solely the order in which IRQ vectors are

The EINVAL is coming from vfio_msi_set_block() here:
https://github.com/torvalds/linux/blob/master/drivers/vfio/pci/vfio_pci_intrs.c#L373

vfio_msi_set_block() is being called from vfio_pci_set_msi_trigger() here on
the second IRQ request:
https://github.com/torvalds/linux/blob/master/drivers/vfio/pci/vfio_pci_intrs.c#L530

We believe the bug is in vfio_pci_set_msi_trigger(), in the 2nd parameter to the call
to vfio_msi_enable() here:
https://github.com/torvalds/linux/blob/master/drivers/vfio/pci/vfio_pci_intrs.c#L533

In both the passing and failing cases, the first IRQ request results in a call
to vfio_msi_enable() at line 533 and the second IRQ request results in the
call to vfio_msi_set_block() at line 530. It is during the first IRQ request
that vfio_msi_enable() sets vdev->num_ctx based on the 2nd parameter (nvec).
vdev->num_ctx is part of the conditional that results in the EINVAL for the
failing case.

In the passing case, vdev->num_ctx is 2. In the failing case, it is 1.

I am attaching two text files containing trace information from systemtap: one for
the failing case and one for the passing case. They contain a lot more information
than is needed, but if you search for vfio_pci_set_msi_trigger and vfio_msi_set_block,
you will see values for some of the call parameters.
