Pull Page Table Isolation (PTI) v4.14 backporting base tree from Ingo Molnar: "This tree contains the v4.14 PTI backport preparatory tree, which consists of four merges of upstream trees and 7 cherry-picked commits, which the upcoming PTI work depends on" NOTE! The resulting tree is exactly the same as the original base tree (ie the diff between this commit and its immediate first parent is empty). The only reason for this merge is literally to have a common point for the actual PTI changes so that the commits can be shared in both the 4.15 and 4.14 trees. * 'WIP.x86-pti.base-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm/kasan: Don't use vmemmap_populate() to initialize shadow locking/barriers: Convert users of lockless_dereference() to READ_ONCE() locking/barriers: Add implicit smp_read_barrier_depends() to READ_ONCE() bpf: fix build issues on um due to mising bpf_perf_event.h perf/x86: Enable free running PEBS for REGS_USER/INTR x86: Make X86_BUG_FXSAVE_LEAK detectable in CPUID on AMD x86/cpufeature: Add User-Mode Instruction Prevention definitions

[ Note, this is a Git cherry-pick of the following commit: d17a1d97: ("x86/mm/kasan: don't use vmemmap_populate() to initialize shadow") ... for easier x86 PTI code testing and back-porting. ] The KASAN shadow is currently mapped using vmemmap_populate() since that provides a semi-convenient way to map pages into init_top_pgt. However, since that no longer zeroes the mapped pages, it is not suitable for KASAN, which requires zeroed shadow memory. Add kasan_populate_shadow() interface and use it instead of vmemmap_populate(). Besides, this allows us to take advantage of gigantic pages and use them to populate the shadow, which should save us some memory wasted on page tables and reduce TLB pressure.

This reverts commits 5c9d2d5c, c7da82b8, and e7fe7b5c. We'll probably need to revisit this, but basically we should not complicate the get_user_pages_fast() case, and checking the actual page table protection key bits will require more care anyway, since the protection keys depend on the exact state of the VM in question. Particularly when doing a "remote" page lookup (ie in somebody elses VM, not your own), you need to be much more careful than this was. Dave Hansen says: "So, the underlying bug here is that we now a get_user_pages_remote() and then go ahead and do the p*_access_permitted() checks against the current PKRU. This was introduced recently with the addition of the new p??_access_permitted() calls. We have checks in the VMA path for the "remote" gups and we avoid consulting PKRU for them. This got missed in the pkeys selftests because I did a ptrace read, but not a *write*. I also didn't explicitly test it against something where a COW needed to be done" It's also not entirely clear that it makes sense to check the protection key bits at this level at all. But one possible eventual solution is to make the get_user_pages_fast() case just abort if it sees protection key bits set, which makes us fall back to the regular get_user_pages() case, which then has a vma and can do the check there if we want to. We'll see. Somewhat related to this all: what we _do_ want to do some day is to check the PAGE_USER bit - it should obviously always be set for user pages, but it would be a good check to have back. Because we have no generic way to test for it, we lost it as part of moving over from the architecture-specific x86 GUP implementation to the generic one in commit e585513b ("x86/mm/gup: Switch GUP to the generic get_user_page_fast() implementation").

git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi由 Linus Torvalds 提交于
Pull SCSI fixes from James Bottomley: "The most important one is the bfa fix because it's easy to oops the kernel with this driver (this includes the commit that corrects the compiler warning in the original), a regression in the new timespec conversion in aacraid and a regression in the Fibre Channel ELS handling patch. The other three are a theoretical problem with termination in the vendor/host matching code and a use after free in lpfc. The additional patches are a fix for an I/O hang in the mq code under certain circumstances and a rare oops in some debugging code" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: scsi: core: Fix a scsi_show_rq() NULL pointer dereference scsi: MAINTAINERS: change FCoE list to linux-scsi scsi: libsas: fix length error in sas_smp_handler() scsi: bfa: fix type conversion warning scsi: core: run queue if SCSI device queue isn't ready and queue is idle scsi: scsi_devinfo: cleanly zero-pad devinfo strings scsi: scsi_devinfo: handle non-terminated strings scsi: bfa: fix access to bfad_im_port_s scsi: aacraid: address UBSAN warning regression scsi: libfc: fix ELS request handling scsi: lpfc: Use after free in lpfc_rq_buf_free()

Currently mdio read/write takes around ~115us as the timeout between status check is set to 100us. By reducing the timeout to 1us mdio read/write takes ~15us to complete. This improves the link up event response.

Move static key increments to the beginning of the init function so they pair 1:1 with decrements in ingress/clsact_destroy, which is called in case ingress/clsact_init fails.

Since in qdisc_create, the destroy op is called when init fails, we don't do cleanup in init and leave it up to destroy. This fixes use-after-free when trying to put already freed block.
