"x86/mm: Flush more aggressively in lazy TLB mode\n\nSince commit:\n\n 94b1b03b519b (\"x86/mm: Rework lazy TLB mode and TLB freshness tracking\")\n\nx86\u0027s lazy TLB mode has been all the way lazy: when running a kernel thread\n(including the idle thread), the kernel keeps using the last user mm\u0027s\npage tables without attempting to maintain user TLB coherence at all.\n\nFrom a pure semantic perspective, this is fine -- kernel threads won\u0027t\nattempt to access user pages, so having stale TLB entries doesn\u0027t matter.\n\nUnfortunately, I forgot about a subtlety. By skipping TLB flushes,\nwe also allow any paging-structure caches that may exist on the CPU\nto become incoherent. This means that we can have a\npaging-structure cache entry that references a freed page table, and\nthe CPU is within its rights to do a speculative page walk starting\nat the freed page table.\n\nI can imagine this causing two different problems:\n\n - A speculative page walk starting from a bogus page table could read\n IO addresses. I haven\u0027t seen any reports of this causing problems.\n\n - A speculative page walk that involves a bogus page table can install\n garbage in the TLB. Such garbage would always be at a user VA, but\n some AMD CPUs have logic that triggers a machine check when it notices\n these bogus entries. I\u0027ve seen a couple reports of this.\n\nBoris further explains the failure mode:\n\n\u003e It is actually more of an optimization which assumes that paging-structure\n\u003e entries are in WB DRAM:\n\u003e\n\u003e \"TlbCacheDis: cacheable memory disable. Read-write. 0\u003dEnables\n\u003e performance optimization that assumes PML4, PDP, PDE, and PTE entries\n\u003e are in cacheable WB-DRAM; memory type checks may be bypassed, and\n\u003e addresses outside of WB-DRAM may result in undefined behavior or NB\n\u003e protocol errors. 1\u003dDisables performance optimization and allows PML4,\n\u003e PDP, PDE and PTE entries to be in any memory type. Operating systems\n\u003e that maintain page tables in memory types other than WB- DRAM must set\n\u003e TlbCacheDis to insure proper operation.\"\n\u003e\n\u003e The MCE generated is an NB protocol error to signal that\n\u003e\n\u003e \"Link: A specific coherent-only packet from a CPU was issued to an\n\u003e IO link. This may be caused by software which addresses page table\n\u003e structures in a memory type other than cacheable WB-DRAM without\n\u003e properly configuring MSRC001_0015[TlbCacheDis]. This may occur, for\n\u003e example, when page table structure addresses are above top of memory. In\n\u003e such cases, the NB will generate an MCE if it sees a mismatch between\n\u003e the memory operation generated by the core and the link type.\"\n\u003e\n\u003e I\u0027m assuming coherent-only packets don\u0027t go out on IO links, thus the\n\u003e error.\n\nTo fix this, reinstate TLB coherence in lazy mode. With this patch\napplied, we do it in one of two ways:\n\n - If we have PCID, we simply switch back to init_mm\u0027s page tables\n when we enter a kernel thread -- this seems to be quite cheap\n except for the cost of serializing the CPU.\n\n - If we don\u0027t have PCID, then we set a flag and switch to init_mm\n the first time we would otherwise need to flush the TLB.\n\nThe /sys/kernel/debug/x86/tlb_use_lazy_mode debug switch can be changed\nto override the default mode for benchmarking.\n\nIn theory, we could optimize this better by only flushing the TLB in\nlazy CPUs when a page table is freed. Doing that would require\nauditing the mm code to make sure that all page table freeing goes\nthrough tlb_remove_page() as well as reworking some data structures\nto implement the improved flush logic.\n\nReported-by: Markus Trippelsdorf \u003cmarkus@trippelsdorf.de\u003e\nReported-by: Adam Borowski \u003ckilobyte@angband.pl\u003e\nSigned-off-by: Andy Lutomirski \u003cluto@kernel.org\u003e\nSigned-off-by: Borislav Petkov \u003cbp@suse.de\u003e\nCc: Borislav Petkov \u003cbp@alien8.de\u003e\nCc: Brian Gerst \u003cbrgerst@gmail.com\u003e\nCc: Daniel Borkmann \u003cdaniel@iogearbox.net\u003e\nCc: Eric Biggers \u003cebiggers@google.com\u003e\nCc: Johannes Hirte \u003cjohannes.hirte@datenkhaos.de\u003e\nCc: Kees Cook \u003ckeescook@chromium.org\u003e\nCc: Kirill A.

swap readahead was introduced, a new knob\n\n /sys/kernel/mm/swap/vma_ra_max_order\n\nwas added as the max window of VMA swap readahead. This is to make it\npossible to use different max window for VMA based readahead and\noriginal physical readahead. But Minchan Kim pointed out that this will\ncause a regression because setting page-cluster sysctl to zero cannot\ndisable swap readahead with the change.\n\nTo fix the regression, the page-cluster sysctl is used as the max window\nof both the VMA based swap readahead and original physical swap\nreadahead. If more fine grained control is needed in the future, more\nknobs can be added as the subordinate knobs of the page-cluster sysctl.\n\nThe vma_ra_max_order knob is deleted. Because the knob was introduced\nin v4.14-rc1, and this patch is targeting being merged before v4.14\nreleasing, there should be no existing users of this newly added ABI.\n\nLink: http://lkml.kernel.org/r/20171011070847.16003-1-ying.huang@intel.com\nFixes: ec560175c0b6fce (\"mm, swap: VMA based swap readahead\")\nSigned-off-by: \"Huang, Ying\" \u003cying.huang@intel.com\u003e\nReported-by: Minchan Kim \u003cminchan@kernel.org\u003e\nAcked-by: Minchan Kim \u003cminchan@kernel.org\u003e\nAcked-by: Michal Hocko \u003cmhocko@suse.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Shaohua Li \u003cshli@kernel.org\u003e\nCc: Hugh Dickins \u003chughd@google.com\u003e\nCc: Fengguang Wu \u003cfengguang.wu@intel.com\u003e\nCc: Tim Chen \u003ctim.c.chen@intel.com\u003e\nCc: Dave Hansen \u003cdave.hansen@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a7b100953aa33a5bbdc3e5e7f2241b9c0704606e", "tree": "3088c7e029b713ac2402e829bd95a68cc66eee63", "parents": [ "ca182551857cc2c1e6a2b7f1e72090a137a15008" ], "author": { "name": "Will Deacon", "email": "will.deacon@arm.com", "time": "Fri Oct 13 15:58:25 2017 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 13 16:18:33 2017 -0700" }, "message": "mm: page_vma_mapped: ensure pmd is loaded with READ_ONCE outside of lock\n\nLoading the pmd without holding the pmd_lock exposes us to races with\nconcurrent updaters of the page tables but, worse still, it also allows\nthe compiler to cache the pmd value in a register and reuse it later on,\neven if we\u0027ve performed a READ_ONCE in between and seen a more recent\nvalue.\n\nIn the case of page_vma_mapped_walk, this leads to the following crash\nwhen the pmd loaded for the initial pmd_trans_huge check is all zeroes\nand a subsequent valid table entry is loaded by check_pmd.

Before this CR4 loading, the guest CR4 refers to L2\nCR4. Because these two CR4\u0027s are in different levels of guest, we\nshould vmx_set_cr4() rather than kvm_set_cr4() here. The latter, which\nis used to handle guest writes to its CR4, checks the guest change to\nCR4 and may fail if the change is invalid.\n\nThe failure may cause trouble. Consider we start\n a L1 guest with non-zero L1 PCID in use,\n (i.e. L1 CR4.PCIDE \u003d\u003d 1 \u0026\u0026 L1 CR3.PCID !\u003d 0)\nand\n a L2 guest with L2 PCID disabled,\n (i.e. L2 CR4.PCIDE \u003d\u003d 0)\nand following events may happen:\n\n1. If kvm_set_cr4() is used in load_vmcs12_host_state() to load L1 CR4\n into guest CR4 (in VMCS01) for L2 to L1 exit, it will fail because\n of PCID check. As a result, the guest CR4 recorded in L0 KVM (i.e.\n vcpu-\u003earch.cr4) is left to the value of L2 CR4.\n\n2. Later, if L1 attempts to change its CR4, e.g., clearing VMXE bit,\n kvm_set_cr4() in L0 KVM will think L1 also wants to enable PCID,\n because the wrong L2 CR4 is used by L0 KVM as L1 CR4. As L1\n CR3.PCID !\u003d 0, L0 KVM will inject GP to L1 guest.\n\nFixes: 4704d0befb072 (\"KVM: nVMX: Exiting from L2 to L1\")\nCc: qemu-stable@nongnu.org\nSigned-off-by: Haozhong Zhang \u003chaozhong.zhang@intel.com\u003e\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\n" }, { "commit": "2d30408ecfd450c8377186615b330d329ded18ea", "tree": "c216f8e271bb812e5d6b1b8e63b87a54bb4b7875", "parents": [ "47a4b71c0b15be08a0f5e3011e71551a269bbe59", "7c80f9e4a588f1925b07134bb2e3689335f6c6d8" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Oct 12 11:17:34 2017 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Thu Oct 12 11:17:34 2017 +0200" }, "message": "Merge tag \u0027fixes-for-v4.14-rc5\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus\n\nFelipe writes:\n\nUSB: fixes for v4.14-rc5\n\nA deadlock fix in dummy-hcd; Fixing a use-after-free bug in composite;\nRenesas got another fix for DMA programming (this time around a fix\nfor receiving ZLP); Tegra PHY got a suspend fix; A memory leak on our\nconfigfs ABI got plugged.\n\nOther than these, a couple other minor fixes on usbtest.\n" }, { "commit": "9d25e3cc83d731ae4eeb017fd07562fde3f80bef", "tree": "e0d0a942a97e23e8062fedb173f40e94a47aae65", "parents": [ "aba2d9a6385a5cc4f7a7e8eb5788e1ddbc213fc0" ], "author": { "name": "Marek Szyprowski", "email": "m.szyprowski@samsung.com", "time": "Mon Oct 09 13:40:23 2017 +0200" }, "committer": { "name": "Joerg Roedel", "email": "jroedel@suse.de", "time": "Thu Oct 12 10:25:11 2017 +0200" }, "message": "iommu/exynos: Remove initconst attribute to avoid potential kernel oops\n\nExynos SYSMMU registers standard platform device with sysmmu_of_match\ntable, what means that this table is accessed every time a new platform\ndevice is registered in a system.

That used to work fine, but changeset\n1f862a68df24 (\"[media] dvb_frontend: move kref to struct dvb_frontend\")\nadded a kref at struct dvb_frontend. So, now, instead of just\nfreeing the data, the error handling do a kref_put().\n\nThat works fine only after dvb_register_frontend() succeeds.\n\nWhile it would be possible to add a helper function that\nwould be initializing earlier the kref, that would require\nchanging every single DVB frontend on non-trivial ways, and\nwould make frontends different than other drivers.\n\nSo, instead of doing that, let\u0027s focus on the real issue:\nonly call kref_put() after kref_init(). That\u0027s easy to\ncheck, as, when the dvb frontend is successfuly registered,\nit will allocate its own private struct.
