It takes the position where to\n        start and end the zeroing which avoids length calculations and\n\tmakes code clearer.\n\nzero_user_segment(page, start, end)\n\n        Same for a single segment.\n\nzero_user(page, start, length)\n\n        Length variant for the case where we know the length.\n\nWe remove the zero_user_page macro. Issues:\n\n1. Its a macro. Inline functions are preferable.\n\n2. The KM_USER0 macro is only defined for HIGHMEM.\n\n   Having to treat this special case everywhere makes the\n   code needlessly complex. The parameter for zeroing is always\n   KM_USER0 except in one single case that we open code.\n\nAvoiding KM_USER0 makes a lot of code not having to be dealing\nwith the special casing for HIGHMEM anymore. Dealing with\nkmap is only necessary for HIGHMEM configurations. In those\nconfigurations we use KM_USER0 like we do for a series of other\nfunctions defined in highmem.h.\n\nSince KM_USER0 is depends on HIGHMEM the existing zero_user_page\nfunction could not be a macro. zero_user_* functions introduced\nhere can be be inline because that constant is not used when these\nfunctions are called.\n\nAlso extract the flushing of the caches to be outside of the kmap.\n\n[akpm@linux-foundation.org: fix nfs and ntfs build]\n[akpm@linux-foundation.org: fix ntfs build some more]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Steven French \u003csfrench@us.ibm.com\u003e\nCc: Michael Halcrow \u003cmhalcrow@us.ibm.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nCc: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: \"J.

This\nhas the annoying \"feature\" that mounting can take a few seconds if the\njournal is large as we have clear it all.

      "message": "[PATCH] Prepare for __copy_from_user_inatomic to not zero missed bytes\n\nThe problem is that when we write to a file, the copy from userspace to\npagecache is first done with preemption disabled, so if the source address is\nnot immediately available the copy fails *and* *zeros* *the* *destination*.\n\nThis is a problem because a concurrent read (which admittedly is an odd thing\nto do) might see zeros rather that was there before the write, or what was\nthere after, or some mixture of the two (any of these being a reasonable thing\nto see).\n\nIf the copy did fail, it will immediately be retried with preemption\nre-enabled so any transient problem with accessing the source won\u0027t cause an\nerror.\n\nThe first copying does not need to zero any uncopied bytes, and doing so\ncauses the problem.  It uses copy_from_user_atomic rather than copy_from_user\nso the simple expedient is to change copy_from_user_atomic to *not* zero out\nbytes on failure.\n\nThe first of these two patches prepares for the change by fixing two places\nwhich assume copy_from_user_atomic does zero the tail.  The two usages are\nvery similar pieces of code which copy from a userspace iovec into one or more\npage-cache pages.  These are changed to remove the assumption.\n\nThe second patch changes __copy_from_user_inatomic* to not zero the tail.\nOnce these are accepted, I will look at similar patches of other architectures\nwhere this is important (ppc, mips and sparc being the ones I can find).\n\nThis patch:\n\nThere is a problem with __copy_from_user_inatomic zeroing the tail of the\nbuffer in the case of an error.  As it is called in atomic context, the error\nmay be transient, so it results in zeros being written where maybe they\nshouldn\u0027t be.\n\nIn the usage in filemap, this opens a window for a well timed read to see data\n(zeros) which is not consistent with any ordering of reads and writes.\n\nMost cases where __copy_from_user_inatomic is called, a failure results in\n__copy_from_user being called immediately.  As long as the latter zeros the\ntail, the former doesn\u0027t need to.  However in *copy_from_user_iovec\nimplementations (in both filemap and ntfs/file), it is assumed that\ncopy_from_user_inatomic will zero the tail.\n\nThis patch removes that assumption, so that after this patch it will\nbe safe for copy_from_user_inatomic to not zero the tail.\n\nThis patch also adds some commentary to filemap.h and asm-i386/uaccess.h.\n\nAfter this patch, all architectures that might disable preempt when\nkmap_atomic is called need to have their __copy_from_user_inatomic* \"fixed\".\nThis includes\n - powerpc\n - i386\n - mips\n - sparc\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Anton Altaparmakov \u003caia21@cantab.net\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Ralf Baechle \u003cralf@linux-mips.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
