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": "318e5313923197e71a94f7b18835151649384b7f", "tree": "d0ceb60fb9c5b4aacbeae3165587064e2e23c86d", "parents": [ "dbaaba1d0abf6871c7db6e3d15a46206bc386db1" ], "author": { "name": "Herbert Xu", "email": "herbert@gondor.apana.org.au", "time": "Tue Aug 05 13:34:30 2008 +0800" }, "committer": { "name": "Herbert Xu", "email": "herbert@gondor.apana.org.au", "time": "Wed Aug 13 20:08:44 2008 +1000" }, "message": "crypto: hash - Add missing top-level functions\n\nThe top-level functions init/update/final were missing for ahash.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\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": "6bf90b2bf4084a64bbcf96a0b93dc64c77288028", "tree": "e2a760beec4bab92de0d611b174d0a7c5b94a4f7", "parents": [ "83ac794f15d2311d8e9e641c73618011f2f7f0a1" ], "author": { "name": "Rami Rosen", "email": "ramirose@gmail.com", "time": "Wed Aug 13 02:35:39 2008 -0700" }, "committer": { "name": "David S.

You can obviously screw up and take the same lock _twice_\n\u003e (which will deadlock), but at least you cannot get into ABBA situations.\n\u003e\n\u003e So maybe the right thing to do is to just teach lockdep about \"lock\n\u003e protection locks\". That would have solved the multi-queue issues for\n\u003e networking too - all the actual network drivers would still have taken\n\u003e just their single queue lock, but the one case that needs to take all of\n\u003e them would have taken a separate top-level lock first.\n\u003e\n\u003e Never mind that the multi-queue locks were always taken in the same order:\n\u003e it\u0027s never wrong to just have some top-level serialization, and anybody\n\u003e who needs to take \u003cn\u003e locks might as well do \u003cn+1\u003e, because they sure as\n\u003e hell aren\u0027t going to be on _any_ fastpaths.\n\u003e\n\u003e So the simplest solution really sounds like just teaching lockdep about\n\u003e that one special case. It\u0027s not \"nesting\" exactly, although it\u0027s obviously\n\u003e related to it.\n\nDo as Linus suggested. The lock protection lock is called nest_lock.\n\nNote that we still have the MAX_LOCK_DEPTH (48) limit to consider, so anything\nthat spills that it still up shit creek.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "4f3e7524b2e703d9f8b02ac338153a53dd7ede66", "tree": "0033ade94f230d6044ad318e3791c55ad611069e", "parents": [ "f82b217e3513fe3af342c0f3ee1494e86250c21c" ], "author": { "name": "Peter Zijlstra", "email": "a.p.zijlstra@chello.nl", "time": "Mon Aug 11 09:30:23 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Aug 11 09:30:23 2008 +0200" }, "message": "lockdep: map_acquire\n\nMost the free-standing lock_acquire() usages look remarkably similar, sweep\nthem into a new helper.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "f82b217e3513fe3af342c0f3ee1494e86250c21c", "tree": "144b724c9e0c491c0983087627000080b25b9852", "parents": [ "1b12bbc747560ea68bcc132c3d05699e52271da0" ], "author": { "name": "Dave Jones", "email": "davej@redhat.com", "time": "Mon Aug 11 09:30:23 2008 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Mon Aug 11 09:30:23 2008 +0200" }, "message": "lockdep: shrink held_lock structure\n\nstruct held_lock {\n u64 prev_chain_key; /* 0 8 */\n struct lock_class * class; /* 8 8 */\n long unsigned int acquire_ip; /* 16 8 */\n struct lockdep_map * instance; /* 24 8 */\n int irq_context; /* 32 4 */\n int trylock; /* 36 4 */\n int read; /* 40 4 */\n int check; /* 44 4 */\n int hardirqs_off; /* 48 4 */\n\n /* size: 56, cachelines: 1 */\n /* padding: 4 */\n /* last cacheline: 56 bytes */\n};\n\nstruct held_lock {\n u64 prev_chain_key; /* 0 8 */\n long unsigned int acquire_ip; /* 8 8 */\n struct lockdep_map * instance; /* 16 8 */\n unsigned int class_idx:11; /* 24:21 4 */\n unsigned int irq_context:2; /* 24:19 4 */\n unsigned int trylock:1; /* 24:18 4 */\n unsigned int read:2; /* 24:16 4 */\n unsigned int check:2; /* 24:14 4 */\n unsigned int hardirqs_off:1; /* 24:13 4 */\n\n /* size: 32, cachelines: 1 */\n /* padding: 4 */\n /* bit_padding: 13 bits */\n /* last cacheline: 32 bytes */\n};\n\n[mingo@elte.hu: shrunk hlock-\u003eclass too]\n[peterz@infradead.org: fixup bit sizes]\nSigned-off-by: Dave Jones \u003cdavej@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\n" } ], "next": "64aa348edc617dea17bbd01ddee4e47886d5ec8c" }
