<george.dunlap@xxxxxxxxxx> Date: Tue Nov 28 13:45:13 2017 +0100 p2m: Check return value of p2m_set_entry() when decreasing reservation If the entire range specified to p2m_pod_decrease_reservation() is marked populate-on-demand, then it will make a single p2m_set_entry() call, reducing its PoD entry count. Unfortunately, in the right circumstances, this p2m_set_entry() call may fail. It that case, repeated calls to decrease_reservation() may cause p2m->pod.entry_count to fall below zero, potentially tripping over BUG_ON()s to the contrary. Instead, check to see if the entry succeeded, and return false if not. The caller will then call guest_remove_page() on the gfns, which will return -EINVAL upon finding no valid memory there to return. Unfortunately if the order > 0, the entry may have partially changed. A domain_crash() is probably the safest thing in that case. Other p2m_set_entry() calls in the same function should be fine, because they are writing the entry at its current order. Nonetheless, check the return value and crash if our assumption turns otu to be wrong. This is part of XSA-247.

Unfortunately, the p2m_set_entry() calls may fail if the underlying pagetable structure needs to change and the domain has exhausted its p2m memory pool: for instance, if we're removing a 2MiB region out of a 1GiB entry (in the p2m_pod_zero_check_superpage() case), or a 4k region out of a 2MiB or larger entry (in the p2m_pod_zero_check() case); and the return value is not checked. The underlying mfn will then be added into the PoD cache, and at some point mapped into another location in the p2m. If the guest afterwards ballons out this memory, it will be freed to the hypervisor and potentially reused by another domain, in spite of the fact that the original domain still has writable mappings to it. There are several places where p2m_set_entry() shouldn't be able to fail, as it is guaranteed to write an entry of the same order that succeeded before. Add a backstop of crashing the domain just in case, and an ASSERT_UNREACHABLE() to flag up the broken assumption on debug builds. While we're here, use PAGE_ORDER_2M rather than a magic constant. This is part of XSA-247.

However, the error is not propagated resulting to the callers to retry infinitely the PoD. Prevent the infinite loop by return false when it is not possible to shatter the large mapping.
