It also permits\nconcurrent calls to synchronize_sched_expedited() to share a single call\nto try_stop_cpu() through use of an atomically incremented\nsynchronize_sched_expedited_count variable. Unfortunately, this is\nsubject to failure as follows:\n\no\tTask A invokes synchronize_sched_expedited(), try_stop_cpus()\n\tsucceeds, but Task A is preempted before getting to the atomic\n\tincrement of synchronize_sched_expedited_count.\n\no\tTask B also invokes synchronize_sched_expedited(), with exactly\n\tthe same outcome as Task A.\n\no\tTask C also invokes synchronize_sched_expedited(), again with\n\texactly the same outcome as Tasks A and B.\n\no\tTask D also invokes synchronize_sched_expedited(), but only\n\tgets as far as acquiring the mutex within try_stop_cpus()\n\tbefore being preempted, interrupted, or otherwise delayed.\n\no\tTask E also invokes synchronize_sched_expedited(), but only\n\tgets to the snapshotting of synchronize_sched_expedited_count.\n\no\tTasks A, B, and C all increment synchronize_sched_expedited_count.\n\no\tTask E fails to get the mutex, so checks the new value\n\tof synchronize_sched_expedited_count. It finds that the\n\tvalue has increased, so (wrongly) assumes that its work\n\thas been done, returning despite there having been no\n\texpedited grace period since it began.\n\nThe solution is to have the lowest-numbered CPU atomically increment\nthe synchronize_sched_expedited_count variable within the\nsynchronize_sched_expedited_cpu_stop() function, which is under\nthe protection of the mutex acquired by try_stop_cpus(). However, this\nalso requires that piggybacking tasks wait for three rather than two\ninstances of try_stop_cpu(), because we cannot control the order in\nwhich the per-CPU callback function occur.\n\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nSigned-off-by: Paul E.

That code was\ndoubly obscure because (a) the code itself lives in lib/bugs.c (for\ndubious reasons) and (b) it gets called from the architecture-specific\n\"module_finalize()\" rather than from generic code.\n\nCalling it from arch-specific code makes no sense what-so-ever to begin\nwith, and is now actively wrong since that code isn\u0027t protected by the\nmodule loading lock any more.\n\nSo this commit moves the \"module_bug_{finalize,cleanup}()\" calls away\nfrom the arch-specific code, and into the generic code - and in the\nprocess protects it with the module_mutex so that the list operations\nare now safe.\n\nFuture fixups:\n - move the module list handling code into kernel/module.c where it\n belongs.\n - get rid of \u0027module_bug_list\u0027 and just use the regular

I tried for so long: this bug goes back to\nKSM swapping in 2.6.33.\n\nNotice how reuse_swap_page() allows an exclusive page to be reused, but\nonly does SetPageDirty if it can delete it from swap cache right then -\nif it\u0027s currently under Writeback, it has to be left in cache and we\ndon\u0027t SetPageDirty, but the page can be reused. Fine, the dirty bit\nwill get set in the pte; but notice how zap_pte_range() does not bother\nto transfer pte_dirty to page_dirty when unmapping a PageAnon.\n\nIf KSM chooses to share such a page, it will look like a clean copy of\nswapcache, and not be written out to swap when its memory is needed;\nthen stale data read back from swap when it\u0027s needed again.\n\nWe could fix this in reuse_swap_page() (or even refuse to reuse a\npage under writeback), but it\u0027s more honest to fix my oversight in\nKSM\u0027s write_protect_page().

It\ndeals with these by attempting to translate them through the current set of\npage tables.\n\nThis is fine for userspace memory and vmalloc()\u0027d areas as they are governed by\npage tables. However, since the regions above 0x80000000 aren\u0027t translated\nthrough the page tables by the MMU, the kernel doesn\u0027t bother to set up page\ntables for them (see paging_init()).\n\nThis means flush_icache_range() as it stands cannot be used to flush regions of\nthe VM area between 0x80000000 and 0x9fffffff where the kernel resides if the\ndata cache is operating in WriteBack mode.\n\nTo fix this, make flush_icache_range() first check for addresses in the upper\nhalf of VM space and deal with them appropriately, before dealing with any\nrange in the page table mapped area.\n\nOrdinarily, this is not a problem, but it has the capacity to make kprobes and\nkgdb malfunction. It should not affect gdbstub, signal frame setup or module\nloading as gdb has its own flush functions, and the others take place in the\npage table mapped area only.\n\nSigned-off-by: David Howells

This forces use of a fresh scatterlist for each DMA\noperation, which makes recycling a single scatterlist impossible.\n\nChange the behavior of the kfifo_dma functions to match the usage of the\ndma_map_sg function. This means that users must respect the returned\nnents value. The sample code is updated to reflect the change.\n\nThis bug is trivial to cause: call kfifo_dma_in_prepare() such that it\nprepares a scatterlist with a single entry comprising the whole fifo.\nThis is the case when you map the entirety of a newly created empty fifo.\nThis causes the setup_sgl() function to mark the first scatterlist entry\nas the end of the chain, no matter what comes after it.\n\nAfterwards, add and remove some data from the fifo such that another call\nto kfifo_dma_in_prepare() will create two scatterlist entries. It returns\nnents\u003d2. However, due to the previous sg_mark_end() call, sg_is_last()\nwill now return true for the first scatterlist element. This causes the\nsample code to print a single scatterlist element when it should print\ntwo.\n\nBy removing the call to sg_mark_end(), we make the API as similar as\npossible to the DMA mapping API. All users are required to respect the\nreturned nents.\n\nSigned-off-by: Ira W.
