<andrew.cooper3@xxxxxxxxxx> Date: Thu Nov 16 12:03:26 2017 +0100 x86/shadow: correct SH_LINEAR mapping detection in sh_guess_wrmap() The fix for XSA-243 / CVE-2017-15592 (c/s bf2b4eadcf379) introduced a change in behaviour for sh_guest_wrmap(), where it had to cope with no shadow linear mapping being present. As the name suggests, guest_vtable is a mapping of the guests pagetable, not Xen's pagetable, meaning that it isn't the pagetable we need to check for the shadow linear slot in. The practical upshot is that a shadow HVM vcpu which switches into 4-level paging mode, with an L4 pagetable that contains a mapping which aliases Xen's SH_LINEAR_PT_VIRT_START will fool the safety check for whether a SHADOW_LINEAR mapping is present. As the check passes (when it should have failed), Xen subsequently falls over the missing mapping with a pagefault such as: (XEN) Pagetable walk from ffff8140a0503880: (XEN) L4[0x102] = 000000046c218063 ffffffffffffffff (XEN) L3[0x102] = 000000046c218063 ffffffffffffffff (XEN) L2[0x102] = 000000046c218063 ffffffffffffffff (XEN) L1[0x103] = 0000000000000000 ffffffffffffffff This is part of XSA-243.

It invokes set_tlbflush_timestamp() on the first iteration, however. Code inside the function takes care of this, but - the assertion in _put_final_page_type() would trigger on the second iteration if time stamps in a debug build are permitted to be sufficiently much wider than the default 6 bits (see WRAP_MASK in flushtlb.c), - it returning -EINTR (for a continuation to be scheduled) would leave the page inconsistent state (until the re-invocation completes). Make the set_tlbflush_timestamp() invocation conditional, bypassing it (for now) only in the case we really can't tolerate the stamp to be stored. This is part of XSA-240.

Corresponding L2/L3 PTE will need be cleared in such scenario. However, concurrent paging structure modifications on different CPUs may cause the L2/L3 PTEs to be already be cleared or set to reference a superpage. Therefore the logic to enumerate the L1/L2 page table and to reset the corresponding L2/L3 PTE need to be protected with spinlock.

However, variable `pl1e` is not protected by the lock before L1 page table is enumerated. A race condition may happen if this code path is invoked simultaneously on different CPUs. For example, `pl1e` value on CPU0 may hold an obsolete value, pointing to a page which has just been freed on CPU1. Besides, before this page is reused, it will still be holding the old PTEs, referencing consecutive page frames. Consequently the `free_xen_pagetable(l2e_to_l1e(ol2e))` will be triggered on CPU0, resulting the unexpected free of a normal page. This patch fixes the above problem by protecting the `pl1e` with the lock. Also, there're other potential race conditions. For instance, the L2/L3 entry may be modified concurrently on different CPUs, by routines such as map_pages_to_xen(), modify_xen_mappings() etc. To fix this, this patch will check the _PAGE_PRESENT and _PAGE_PSE flags, after the spinlock is obtained, for the corresponding L2/L3 entry.

It is not used by Linux or MiniOS; but it is used by NetBSD and Novell Netware. There are significant numbers of people who are never going to use the feature, along with significant numbers who need the feature. Add a Kconfig option for the feature (default to 'y'). Also add a command-line option to control whether PV linear pagetables are allowed (default to 'true'). NB that we leave linear_pt_count in the page struct. It's in a union, so its presence doesn't increase the size of the data struct. Changing the layout of the other elements based on configuration options is asking for trouble however; so we'll just leave it there and ASSERT that it's zero.
