由 Trond Myklebust 提交于
The previous fix broke recovery of delegated stateids because it assumes that if we did not mark the delegation as suspect, then the delegation has effectively been revoked, and so it removes that delegation irrespectively of whether or not it is valid and still in use. While this is "mostly harmless" for ordinary I/O, we've seen pNFS fail with LAYOUTGET spinning in an infinite loop while complaining that we're using an invalid stateid (in this case the all-zero stateid). What we rather want to do here is ensure that the delegation is always correctly marked as needing testing when that is the case. So we want to close the loophole offered by nfs4_schedule_stateid_recovery(), which marks the state as needing to be reclaimed, but not the delegation that may be backing it.

Patch series "mmu_notifiers follow ups". Tetsuo has noticed some fallouts from 93065ac7 ("mm, oom: distinguish blockable mode for mmu notifiers"). One of them has been fixed and picked up by AMD/DRM maintainer [1]. XEN issue is fixed by patch 1. I have also clarified expectations about blockable semantic of invalidate_range_end. Finally the last patch removes MMU_INVALIDATE_DOES_NOT_BLOCK which is no longer used nor needed. [1] http://lkml.kernel.org/r/20180824135257.GU29735@dhcp22.suse.cz This patch (of 3): 93065ac7 ("mm, oom: distinguish blockable mode for mmu notifiers") has introduced blockable parameter to all mmu_notifiers and the notifier has to back off when called in !blockable case and it could block down the road. The above commit implemented that for mn_invl_range_start but both in_range checks are done unconditionally regardless of the blockable mode and as such they would fail all the time for regular calls. Fix this by checking blockable parameter as well. Once we are there we can remove the stale TODO. The lock has to be sleepable because we wait for completion down in gnttab_unmap_refs_sync.

Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

The !CONFIG_GENERIC_IOMAP version of ioport_map uses MMIO_UPPER_LIMIT to prevent users from making I/O accesses outside the expected I/O range - however it erroneously treats MMIO_UPPER_LIMIT as a mask which is contradictory to its other users. The introduction of CONFIG_INDIRECT_PIO, which subtracts an arbitrary amount from IO_SPACE_LIMIT to form MMIO_UPPER_LIMIT, results in ioport_map mangling the given port rather than capping it. We address this by aligning more closely with the CONFIG_GENERIC_IOMAP implementation of ioport_map by using the comparison operator and returning NULL where the port exceeds MMIO_UPPER_LIMIT. Though note that we preserve the existing behavior of masking with IO_SPACE_LIMIT such that we don't break existing buggy drivers that somehow rely on this masking.

Jann Horn points out that the vmacache_flush_all() function is not only potentially expensive, it's buggy too. It also happens to be entirely unnecessary, because the sequence number overflow case can be avoided by simply making the sequence number be 64-bit. That doesn't even grow the data structures in question, because the other adjacent fields are already 64-bit. So simplify the whole thing by just making the sequence number overflow case go away entirely, which gets rid of all the complications and makes the code faster too. Win-win. [ Oleg Nesterov points out that the VMACACHE_FULL_FLUSHES statistics also just goes away entirely with this ] Reported-by: NJann Horn <jannh@google.com> Suggested-by: NWill Deacon <will.deacon@arm.com> Acked-by: NDavidlohr Bueso <dave@stgolabs.net> Cc: Oleg Nesterov <oleg@redhat.com> Cc: stable@kernel.org Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
