See commit 377bf1e4.\n\nIt\u0027s braindead in the first place to call disable_irq_nosync in shared\nhandlers, but ....\n\nMoving this call after we installed the handler looks innocent, but it\nis very subtle broken on SMP.\n\nInterrupt handlers rely on the fact, that the irq core prevents\nreentrancy.\n\nNow this debug call violates that promise because we run the handler\nw/o the IRQ_INPROGRESS protection - which we cannot apply here because\nthat would result in a possibly forever masked interrupt line.\n\nA concurrent real hardware interrupt on a different CPU results in\nhandler reentrancy and can lead to complete wreckage, which was\nunfortunately observed in reality and took a fricking long time to\ndebug.\n\nLeave the code here for now. We want this debug feature, but that\u0027s\nnot easy to fix. We really should get rid of those\ndisable_irq_nosync() abusers and remove that function completely.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Anton Vorontsov \u003cavorontsov@ru.mvista.com\u003e\nCc: David Woodhouse \u003cdwmw2@infradead.org\u003e\nCc: Arjan van de Ven \u003carjan@infradead.org\u003e\nCc: stable@kernel.org # .28 -\u003e .37\n" }, { "commit": "c1ee6264280e740a9d3ff3feef38642cf0a57013", "tree": "a5d3b9ce791551657458d53eafb47533ee34509a", "parents": [ "0cc9d5257857608ba85885b75fcada13d359b5d1" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Thu Feb 17 17:45:15 2011 +0100" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Sat Feb 19 12:10:51 2011 +0100" }, "message": "genirq: Prevent access beyond allocated_irqs bitmap\n\nLars-Peter Clausen pointed out:\n\n I stumbled upon this while looking through the existing archs using\n SPARSE_IRQ. Even with SPARSE_IRQ the NR_IRQS is still the upper\n limit for the number of IRQs.\n\n Both PXA and MMP set NR_IRQS to IRQ_BOARD_START, with\n IRQ_BOARD_START being the number of IRQs used by the core.\n\n In various machine files the nr_irqs field of the ARM machine\n defintion struct is then set to \"IRQ_BOARD_START + NR_BOARD_IRQS\".\n\n As a result \"nr_irqs\" will greater then NR_IRQS which then again\n causes the \"allocated_irqs\" bitmap in the core irq code to be\n accessed beyond its size overwriting unrelated data.\n\nThe core code really misses a sanity check there.\n\nThis went unnoticed so far as by chance the compiler/linker places\ndata behind that bitmap which gets initialized later on those affected\nplatforms.\n\nSo the obvious fix would be to add a sanity check in early_irq_init()\nand break all affected platforms. Though that check wants to be\nbackported to stable as well, which will require to fix all known\nproblematic platforms and probably some more yet not known ones as\nwell. Lots of churn.\n\nA way simpler solution is to allocate a slightly larger bitmap and\navoid the whole churn w/o breaking anything.

Implement an approach proposed by David Miller:\nuse an array of const pointers to refer to the individual structures, and export\nthis pointer array through the linker script rather than the structures per se.\nIt will consume 32 extra bytes per tracepoint (24 for structure padding and 8\nfor the pointers), but are less likely to break due to compiler changes.\n\nHistory:\n\ncommit 7e066fb8 tracepoints: add DECLARE_TRACE() and DEFINE_TRACE()\nadded the aligned(32) type and variable attribute to the tracepoint structures\nto deal with gcc happily aligning statically defined structures on 32-byte\nmultiples.\n\nOne attempt was to use a 8-byte alignment for tracepoint structures by applying\nboth the variable and type attribute to tracepoint structures definitions and\ndeclarations. It worked fine with gcc 4.5.1, but broke with gcc 4.4.4 and 4.4.5.\n\nThe reason is that the \"aligned\" attribute only specify the _minimum_ alignment\nfor a structure, leaving both the compiler and the linker free to align on\nlarger multiples. Because tracepoint.c expects the structures to be placed as an\narray within each section, up-alignment cause NULL-pointer exceptions due to the\nextra unexpected padding.\n\n(this patch applies on top of -tip)\n\nSigned-off-by: Mathieu Desnoyers \u003cmathieu.desnoyers@efficios.com\u003e\nAcked-by: David S.
