Summary
vfio/pci: Lock external INTx masking ops
Details

In the Linux kernel, the following vulnerability has been resolved:

vfio/pci: Lock external INTx masking ops

Mask operations through config space changes to DisINTx may race INTx configuration changes via ioctl. Create wrappers that add locking for paths outside of the core interrupt code.

In particular, irqtype is updated holding igate, therefore testing isintx() requires holding igate. For example clearing DisINTx from config space can otherwise race changes of the interrupt configuration.

This aligns interfaces which may trigger the INTx eventfd into two camps, one side serialized by igate and the other only enabled while INTx is configured. A subsequent patch introduces synchronization for the latter flows.
