<paul.durrant@xxxxxxxxxx> Date: Fri Jul 5 10:25:46 2019 +0200 x86/msi: fix loop termination condition in pci_msi_conf_write_intercept() The for loop that deals with MSI masking is coded as follows: for ( pos = 0; pos < entry->msi.nvec; ++pos, ++entry ) Thus the loop termination condition is dereferencing a struct pointer that is being incremented by the loop. A block of MSI entries stores the number of vectors in entry[0].msi.nvec, with all subsequent entries using a value of 0. Therefore, for a block of two or more MSIs will terminate the loop early, as entry[1].msi.nvec is 0. However, for a single MSI, ++entry moves the pointer out of bounds, and a bogus read is used for the termination condition. In the case that the loop body gets entered, there are subsequent OoB writes which clobber adjacent memory in the heap. This patch simply initializes a stack variable to the value of entry->msi.nvec before starting the loop and then uses that in the termination condition instead.

If such a guest appears to be started on an XSAVE enabled CPU and the feature is explicitly cleared in policy, leaked OSXSAVE bit from Xen will lead to guest crash early in boot.

The involved MSR (0xC0010055), however, is fully reserved starting from Fam16, and the two bits of interest are reserved for Fam12 and onwards (albeit I admit I wasn't able to find any Fam13 doc).

The commit having no description, it is hard to tell whether this was a mechanical dec->hex conversion mistake, or indeed intended. In any event the NB_CFG handling needs to be restricted to Fam16 and below: Fam17 doesn't really have such an MSR anymore. As per observation it's read-zero / write-discard now, so make PV uniformly (with the exception of pinned Dom0 vCPU-s) behave so, just like HVM already does. Mirror the NB_CFG behavior to MSR_FAM10H_MMIO_CONF_BASE as well, except that here the vendor/model check is kept in place (for now at least). A non-MMCFG extended config space access mechanism still appears to exist, but code to deal with it will need to be written down the road, when it can actually be tested.

There is a test in hpet_set_timer(), specific to 32-bit timers, that tries to disambiguate between a comparator value that is in the past and one that is sufficiently far in the future that it wraps. This is done by assuming that the delta between the main counter and comparator will be 'small' [1], if the comparator value is in the past. Unfortunately, more often than not, this is not the case if the timer is being re-started after a migrate and so the timer is set to fire far in the future (in excess of a minute in several observed cases) rather then set to fire immediately. This has a rather odd symptom where the guest console is alive enough to be able to deal with mouse pointer re-rendering, but any keyboard activity or mouse clicks yield no response. This patch simply adds an extra check of 'creation_finished' into hpet_set_timer() so that the 'small' time test is omitted when the function is called to restart timers after migration, and thus any negative delta causes a timer to fire immediately.
