kernel_fpu_begin() and kernel_fpu_end()\naround the padlock instructions fix the oops.\n\nSuresh wrote:\n\nThese padlock instructions though don\u0027t use/touch SSE registers, but it behaves\nsimilar to other SSE instructions. For example, it might cause DNA faults\nwhen cr0.ts is set. While this is a spurious DNA trap, it might cause\noops with the recent fpu code changes.\n\nThis is the code sequence that is probably causing this problem:\n\na) new app is getting exec\u0027d and it is somewhere in between\n start_thread() and flush_old_exec() in the load_xyz_binary()\n\nb) At pont \"a\", task\u0027s fpu state (like TS_USEDFPU, used_math() etc) is\n cleared.\n\nc) Now we get an interrupt/softirq which starts using these encrypt/decrypt\n routines in the network stack. This generates a math fault (as\n cr0.ts is \u00271\u0027) which sets TS_USEDFPU and restores the math that is\n in the task\u0027s xstate.\n\nd) Return to exec code path, which does start_thread() which does\n free_thread_xstate() and sets xstate pointer to NULL while\n the TS_USEDFPU is still set.\n\ne) At the next context switch from the new exec\u0027d task to another task,\n we have a scenarios where TS_USEDFPU is set but xstate pointer is null.\n This can cause an oops during unlazy_fpu() in __switch_to()\n\nNow:\n\n1) This should happen with or with out pre-emption. Viro also encountered\n similar problem with out CONFIG_PREEMPT.\n\n2) kernel_fpu_begin() and kernel_fpu_end() will fix this problem, because\n kernel_fpu_begin() will manually do a clts() and won\u0027t run in to the\n situation of setting TS_USEDFPU in step \"c\" above.\n\n3) This was working before the fpu changes, because its a spurious\n math fault which doesn\u0027t corrupt any fpu/sse registers and the task\u0027s\n math state was always in an allocated state.\n\nWith out the recent lazy fpu allocation changes, while we don\u0027t see oops,\nthere is a possible race still present in older kernels(for example,\nwhile kernel is using kernel_fpu_begin() in some optimized clear/copy\npage and an interrupt/softirq happens which uses these padlock\ninstructions generating DNA fault).\n\nThis is the failing scenario that existed even before the lazy fpu allocation\nchanges:\n\n0. CPU\u0027s TS flag is set\n\n1. kernel using FPU in some optimized copy routine and while doing\nkernel_fpu_begin() takes an interrupt just before doing clts()\n\n2. Takes an interrupt and ipsec uses padlock instruction. And we\ntake a DNA fault as TS flag is still set.\n\n3. We handle the DNA fault and set TS_USEDFPU and clear cr0.ts\n\n4. We complete the padlock routine\n\n5. Go back to step-1, which resumes clts() in kernel_fpu_begin(), finishes\nthe optimized copy routine and does kernel_fpu_end(). At this point,\nwe have cr0.ts again set to \u00271\u0027 but the task\u0027s TS_USEFPU is stilll\nset and not cleared.\n\n6. Now kernel resumes its user operation. And at the next context\nswitch, kernel sees it has do a FP save as TS_USEDFPU is still set\nand then will do a unlazy_fpu() in __switch_to(). unlazy_fpu()\nwill take a DNA fault, as cr0.ts is \u00271\u0027 and now, because we are\nin __switch_to(), math_state_restore() will get confused and will\nrestore the next task\u0027s FP state and will save it in prev tasks\u0027s FP state.\nRemember, in __switch_to() we are already on the stack of the next task\nbut take a DNA fault for the prev task.\n\nThis causes the fpu leakage.\n\nFix the padlock instruction usage by calling them inside the\ncontext of new routines irq_ts_save/restore(), which clear/restore cr0.ts\nmanually in the interrupt context. This will not generate spurious DNA\nin the context of the interrupt which will fix the oops encountered and\nthe possible FPU leakage issue.\n\nReported-and-bisected-by: Wolfgang Walter \u003cwolfgang.walter@stwm.de\u003e\nSigned-off-by: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\n" }, { "commit": "a12e61df4fa1cfae7a6b76976fa65a6fcb048e3f", "tree": "957c915298b299902aa80afa7c78e94c71b3dc25", "parents": [ "7b27718bdb1b70166383dec91391df5534d449ee", "30a2f3c60a84092c8084dfe788b710f8d0768cd4" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Aug 13 13:08:47 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Aug 13 13:08:47 2008 +0200" }, "message": "Merge commit \u0027v2.6.27-rc3\u0027 into x86/urgent\n" }, { "commit": "0ed89b06e49c326bff81d81f24b9ba955eb912d5", "tree": "7e54e48c84d6aa4a067ee67c4d688145b1303258", "parents": [ "b74548e76a0eab1f29546e7c5a589429c069a680" ], "author": { "name": "Johannes Weiner", "email": "hannes@saeurebad.de", "time": "Wed Aug 13 10:17:24 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Aug 13 11:57:18 2008 +0200" }, "message": "x86: propagate new nonpanic bootmem macros to CONFIG_HAVE_ARCH_BOOTMEM_NODE\n\nCommit 74768ed833344b \"page allocator: use no-panic variant of\nalloc_bootmem() in alloc_large_system_hash()\" introduced two new\n_nopanic macros which are undefined for CONFIG_HAVE_ARCH_BOOTMEM_NODE.\n\nSigned-off-by: Johannes Weiner \u003channes@saeurebad.de\u003e\nAcked-by: \"Jan Beulich\" \u003cjbeulich@novell.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "7019b1b50097a94d0f8a77b81bee0b19b108c634", "tree": "4213c3fc8a1459894c49eae167744fa96be1e93e", "parents": [ "f08c0761d6ff79e2f4c81f95fd01b761e0410785", "b74548e76a0eab1f29546e7c5a589429c069a680" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 11 16:44:35 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Aug 11 16:44:35 2008 -0700" }, "message": "Merge branch \u0027x86-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027x86-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n x86: fix 2.6.27rc1 cannot boot more than 8CPUs\n x86: make \"apic\" an early_param() on 32-bit, NULL check\n EFI, x86: fix function prototype\n x86, pci-calgary: fix function declaration\n x86: work around gcc 3.4.x bug\n x86: make \"apic\" an early_param() on 32-bit\n x86, debug: tone down arch/x86/kernel/mpparse.c debugging printk\n x86_64: restore the proper NR_IRQS define so larger systems work.\n x86: Restore proper vector locking during cpu hotplug\n x86: Fix broken VMI in 2.6.27-rc..\n x86: fdiv bug detection fix\n" }, { "commit": "b0fbaa6b5976962434349849673b9ff63631b6d4", "tree": "4bc19d6c321643be89684102a5fdae567702d02d", "parents": [ "9b0094f7f289d752868aae1a3984517d712cbb22" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Thu Aug 07 15:12:39 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Aug 11 18:50:19 2008 +0200" }, "message": "EFI, x86: fix function prototype\n\nFix function prototype in header file to match source code:\n\nlinux-next-20080807/arch/x86/kernel/efi_64.c:100:14: error: symbol \u0027efi_ioremap\u0027 redeclared with different type (originally declared at include2/asm/efi.h:89) - different address spaces\n\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "3c7569b284e1be55d086b61a70d9f545326f6d74", "tree": "18b36c05d17bc92441d1f007084fa4b98b7e9f9b", "parents": [ "d388e5fdc461344d04307a3fa83862b9ed429647" ], "author": { "name": "Eric W.

Page table existence is guaranteed by\nturning interrupts off (combined with the fact that we\u0027re always looking\nup the current mm, means we can do the lockless page table walk within the\nconstraints of the TLB shootdown design). Basically we can do this\nlockless pagetable walk in a similar manner to the way the CPU\u0027s pagetable\nwalker does not have to take any locks to find present ptes.\n\nThis patch (combined with the subsequent ones to convert direct IO to use\nit) was found to give about 10% performance improvement on a 2 socket 8\ncore Intel Xeon system running an OLTP workload on DB2 v9.5\n\n \"To test the effects of the patch, an OLTP workload was run on an IBM\n x3850 M2 server with 2 processors (quad-core Intel Xeon processors at\n 2.93 GHz) using IBM DB2 v9.5 running Linux 2.6.24rc7 kernel. Comparing\n runs with and without the patch resulted in an overall performance\n benefit of ~9.8%. Correspondingly, oprofiles showed that samples from\n __up_read and __down_read routines that is seen during thread contention\n for system resources was reduced from 2.8% down to .05%. Monitoring the\n /proc/vmstat output from the patched run showed that the counter for\n fast_gup contained a very high number while the fast_gup_slow value was\n zero.\"\n\n(fast_gup is the old name for get_user_pages_fast, fast_gup_slow is a\ncounter we had for the number of times the slowpath was invoked).\n\nThe main reason for the improvement is that DB2 has multiple threads each\nissuing direct-IO. Direct-IO uses get_user_pages, and thus the threads\ncontend the mmap_sem cacheline, and can also contend on page table locks.\n\nI would anticipate larger performance gains on larger systems, however I\nthink DB2 uses an adaptive mix of threads and processes, so it could be\nthat thread contention remains pretty constant as machine size increases.\nIn which case, we stuck with \"only\" a 10% gain.\n\nThe downside of using get_user_pages_fast is that if there is not a pte\nwith the correct permissions for the access, we end up falling back to\nget_user_pages and so the get_user_pages_fast is a bit of extra work.\nHowever this should not be the common case in most performance critical\ncode.\n\n[akpm@linux-foundation.org: coding-style fixes]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: Kconfig fix]\n[akpm@linux-foundation.org: Makefile fix/cleanup]\n[akpm@linux-foundation.org: warning fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Dave Kleikamp \u003cshaggy@austin.ibm.com\u003e\nCc: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\nCc: Zach Brown \u003czach.brown@oracle.com\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nReviewed-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a0a8f5364a5ad248aec6cb705e0092ff563edc2f", "tree": "fe942b13adc527f66103d529c2ee91da05086d1c", "parents": [ "2682497245e7d22160ae63032c378745a7f2cfe5" ], "author": { "name": "Nick Piggin", "email": "npiggin@suse.de", "time": "Fri Jul 25 19:45:20 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jul 26 12:00:05 2008 -0700" }, "message": "x86: implement pte_special\n\nImplement the pte_special bit for x86.

So I\nCC\u0027ed this to KVM camp. Comments are appreciated.\n\nA pointer to dma_mapping_ops to struct dev_archdata is added. If the\npointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it\u0027s\nNULL, the system-wide dma_ops pointer is used as before.\n\nIf it\u0027s useful for KVM people, I plan to implement a mechanism to register\na hook called when a new pci (or dma capable) device is created (it works\nwith hot plugging). It enables IOMMUs to set up an appropriate\ndma_mapping_ops per device.\n\nThe major obstacle is that dma_mapping_error doesn\u0027t take a pointer to the\ndevice unlike other DMA operations. So x86 can\u0027t have dma_mapping_ops per\ndevice. Note all the POWER IOMMUs use the same dma_mapping_error function\nso this is not a problem for POWER but x86 IOMMUs use different\ndma_mapping_error functions.\n\nThe first patch adds the device argument to dma_mapping_error. The patch\nis trivial but large since it touches lots of drivers and dma-mapping.h in\nall the architecture.\n\nThis patch:\n\ndma_mapping_error() doesn\u0027t take a pointer to the device unlike other DMA\noperations. So we can\u0027t have dma_mapping_ops per device.\n\nNote that POWER already has dma_mapping_ops per device but all the POWER\nIOMMUs use the same dma_mapping_error function. x86 IOMMUs use device\nargument.\n\n[akpm@linux-foundation.org: fix sge]\n[akpm@linux-foundation.org: fix svc_rdma]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix bnx2x]\n[akpm@linux-foundation.org: fix s2io]\n[akpm@linux-foundation.org: fix pasemi_mac]\n[akpm@linux-foundation.org: fix sdhci]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix sparc]\n[akpm@linux-foundation.org: fix ibmvscsi]\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Muli Ben-Yehuda \u003cmuli@il.ibm.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6ffac1e90a17ea0aded5c581204397421eec91b6", "tree": "c5ae5b695f1306f5415b5bf3968b4fcf69e823a1", "parents": [ "024e8ac04453b3525448c31ef39848cf675ba6db" ], "author": { "name": "Suresh Siddha", "email": "suresh.b.siddha@intel.com", "time": "Thu Jul 24 18:07:56 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sat Jul 26 16:37:04 2008 +0200" }, "message": "x64, fpu: fix possible FPU leakage in error conditions\n\nOn Thu, Jul 24, 2008 at 03:43:44PM -0700, Linus Torvalds wrote:\n\u003e So how about this patch as a starting point?

It adds a new syscall\npaccept. This syscall differs from accept in that it adds (at the userlevel)\ntwo additional parameters:\n\n- a signal mask\n- a flags value\n\nThe flags parameter can be used to set flag like SOCK_CLOEXEC. This is\nimlpemented here as well. Some people argued that this is a property which\nshould be inherited from the file desriptor for the server but this is against\nPOSIX. Additionally, we really want the signal mask parameter as well\n(similar to pselect, ppoll, etc). So an interface change in inevitable.\n\nThe flag value is the same as for socket and socketpair. I think diverging\nhere will only create confusion. Similar to the filesystem interfaces where\nthe use of the O_* constants differs, it is acceptable here.\n\nThe signal mask is handled as for pselect etc. The mask is temporarily\ninstalled for the thread and removed before the call returns. I modeled the\ncode after pselect. If there is a problem it\u0027s likely also in pselect.\n\nFor architectures which use socketcall I maintained this interface instead of\nadding a system call.

We get a false flood trigger on the kmap ptes, which results in the\nmmu spending all its time setting up and tearing down shadows.\n\nFix by setting the shadow accessed bit on emulated accesses.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "d2ebb4103ff349af6dac14955bf93e57487a6694", "tree": "5c205c2e36c4c4334855455336427d676e9535c0", "parents": [ "af9ca2d703f4cefbf6441bfe127c4191092ad394" ], "author": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Wed Apr 30 17:56:04 2008 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Sun Jul 20 12:40:48 2008 +0300" }, "message": "KVM: SVM: add tracing support for TDP page faults\n\nTo distinguish between real page faults and nested page faults they should be\ntraced as different events.

There\u0027s a reason that arch/x86/kernel/entry_32.S\n\u003e special-cases the _TIF_NEED_RESCHED flag: we don\u0027t want to exit out of\n\u003e vm86 mode unnecessarily.\n\u003e\n\u003e See the \"work_notifysig_v86\" label, and how it does that\n\u003e \"save_v86_state()\" thing etc etc.\n\nRight, I never liked having to fiddle with those TIF flags. Initially I\nneeded it because the hrtimer base lock could not nest in the rq lock.\nThat however is fixed these days.\n\nCurrently the only reason left to fiddle with the TIF flags is remote\nwakeups. We cannot program a remote cpu\u0027s hrtimer. I\u0027ve been thinking\nabout using the new and improved IPI function call stuff to implement\nhrtimer_start_on().\n\nHowever that does require that smp_call_function_single(.wait\u003d0) works\nfrom interrupt context - /me looks at the latest series from Jens - Yes\nthat does seem to be supported, good.\n\nHere\u0027s a stab at cleaning this stuff up ...\n\nMihai reported test success as well.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nTested-by: Mihai Moldovan \u003cionic@ionic.de\u003e\nCc: Michal Januszewski \u003cspock@gentoo.org\u003e\nCc: Antonino Daplas \u003cadaplas@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "94a1e869c7b96a9d30e260084866383a145fd8ae", "tree": "9331e15facc9af794ad1c21aaa231d4e5460eb80", "parents": [ "1bd9d6b64e1474f1a03f8660e8721d746cffae57" ], "author": { "name": "Mike Travis", "email": "travis@sgi.com", "time": "Fri Jul 18 18:11:31 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jul 20 10:21:11 2008 +0200" }, "message": "NR_CPUS: Replace per_cpu(..., smp_processor_id()) with __get_cpu_var\n\n * Slight optimization when getting one\u0027s own cpu_info percpu data.\n\nSigned-off-by: Mike Travis \u003ctravis@sgi.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c4dc59ae7af8c1c116d2cb4dffba337f032a6bee", "tree": "09c40158db101e722aebdc6592291574d8f34f6b", "parents": [ "63b5d7af2556a7de6bf72c5dd0b85a32fb4c3767" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jul 20 09:31:24 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jul 20 09:31:24 2008 +0200" }, "message": "x86, VisWS: turn into generic arch, eliminate leftover files\n\nremove unused leftovers.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "63b5d7af2556a7de6bf72c5dd0b85a32fb4c3767", "tree": "83465d3c04f62c241d08cc7663328374e9edea4d", "parents": [ "64898a8bad8c94ad7a4bd5cc86b66edfbb081f4a" ], "author": { "name": "Yinghai Lu", "email": "yhlu.kernel@gmail.com", "time": "Sat Jul 19 18:02:26 2008 -0700" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Jul 20 09:25:52 2008 +0200" }, "message": "x86: add -\u003epre_time_init to x86_quirks\n\nso NUMAQ can use that to call numaq_pre_time_init()\n\nThis allows us to remove a NUMAQ special from arch/x86/kernel/setup.c.\n\n(and paves the way to remove the NUMAQ subarch)\n\nSigned-off-by: Yinghai Lu \u003cyhlu.kernel@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" } ], "next": "64898a8bad8c94ad7a4bd5cc86b66edfbb081f4a" }
