This gives a compromised emulator a chance to change the state back between the two reads, potentially keeping Xen in a loop indefinitely. Instead: * Read p->state once in each of the wait_on_xen_event_channel() tests, * re-use that value the next time around, * and insist that the states continue to transition "forward" (with the exception of the transition to STATE_IOREQ_NONE). This is XSA-262.

Currently HPET interrupts are always treated as ISA and thus injected through the vPIC. This is wrong because HPET interrupts when not in legacy mode should be injected from the IO-APIC. To make things worse, the supported interrupt routing values are set to [20..23], which clearly falls outside of the ISA range, thus leading to an ASSERT in debug builds or memory corruption in non-debug builds because the interrupt injection code will write out of the bounds of the arch.hvm_domain.vpic array. Since the HPET interrupt source can change between ISA and IO-APIC always destroy the timer before changing the mode, or else Xen risks changing it while the timer is active. Note that vpt interrupt injection is racy in the sense that the vIO-APIC RTE entry can be written by the guest in between the call to pt_irq_masked and hvm_ioapic_assert, or the call to pt_update_irq and pt_intr_post. Those are not deemed to be security issues, but rather quirks of the current implementation. In the worse case the guest might lose interrupts or get multiple interrupt vectors injected for the same timer source. This is part of XSA-261. Address actual and potential compiler warnings. Fix formatting.

Swap it out for a ratelimited printk with just enough information to work out what is going on. Not all #DB exceptions are traps, so blindly continuing is not a safe action to take. We don't let PV guests select these settings in the real %dr7 to begin with, but for added safety against unexpected situations, detect the fault cases and crash in an obvious manner.

Use an interrupt stack table for #DB to prevent the exception being taken with a guest controlled stack pointer.

The normal exception path is simplified as a result, and compat_post_handle_exception() is removed entirely.

Have the handler follow the manuals guidance, which avoids leaking hypervisor debugging activities into guest context.

Looking at c/s 31ae587e6f which introduced the smap_check logic, it exists only to work around a bug in guest_walk_tables() was resolved by the aformentioned commit. Remove the unused variables and associated infrastructure.
