The issue exists on other platforms\nwith inefficient unaligned access and adding them piecemeal would be an\nunmaintainable mess.\n\nThis patch uses Dave Miller\u0027s suggestion of using a combination of\nCONFIG_64BIT \u0026\u0026 !CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS to determine\nwhether alignment is needed.\n\nNote that this will cause breakage on those platforms with applications\nlike iotop which had hard-coded offsets into the packet to access the\ntaskstats structure.\n\nThe message seen on systems without the alignment fixes looks like: kernel\nunaligned access to 0xe000023879dca9bc, ip\u003d0xa000000100133d10\n\nThe addresses may vary but resolve to locations inside __delayacct_add_tsk.\n\niotop makes what I\u0027d call unreasonable assumptions about the contents of a\nnetlink genetlink packet containing generic attributes. They\u0027re typed and\nhave headers that specify value lengths, so the client can (should)\nidentify and skip the ones the client doesn\u0027t understand.\n\nThe kernel, as of version 2.6.36, presented a packet like so:\n+--------------------------------+\n| genlmsghdr - 4 bytes |\n+--------------------------------+\n| NLA header - 4 bytes | /* Aggregate header */\n+-+------------------------------+\n| | NLA header - 4 bytes | /* PID header */\n| +------------------------------+\n| | pid/tgid - 4 bytes |\n| +------------------------------+\n| | NLA header - 4 bytes | /* stats header */\n| + -----------------------------+ \u003c- oops. aligned on 4 byte boundary\n| | struct taskstats - 328 bytes |\n+-+------------------------------+\n\nThe iotop code expects that the kernel will behave as it did then,\nassuming that the packet format is set in stone. The format is set in\nstone, but the packet offsets are not. There\u0027s nothing in the packet\nformat that guarantees that the packet will be sent in exactly the same\nway. The attribute contents are set (or versioned) and the aggregate\ncontents are set but they can be anywhere in the packet.\n\nThe issue here isn\u0027t that an unaligned structure gets passed to userspace,\nit\u0027s that the NLA infrastructure has something of a weakness: The 4 byte\nattribute header may force the payload to be unaligned. The taskstats\nstructure is created at an unaligned location and then 64-bit values are\noperated on inside the kernel, so the unaligned access warnings gets\nspewed everywhere.\n\nIt\u0027s possible to use the unaligned access API to operate on the structure\nin the kernel but it seems like a wasted effort to work around userspace\ncode that isn\u0027t following the packet format. Any new additions would also\nneed the be worked around. It\u0027s a maintenance nightmare.\n\nThe conclusion of the earlier discussion seemed to be \"ok fine, if we have\nto break it, don\u0027t break it on arches that don\u0027t have the problem.\" Dave\npointed out that the unaligned access problem doesn\u0027t only exist on ia64,\nbut also on other 64-bit arches that don\u0027t have efficient unaligned access\nand it should be fixed there as well. The committed version of the patch\nand this addition keep with the conclusion of that discussion not to break\nit unnecessarily, which the pid padding and the packet padding fixes did\ndo. x86_64 and powerpc don\u0027t suffer this problem so they shouldn\u0027t suffer\nthe solution. Other 64-bit architectures do and will, though.\n\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nReported-by: David S. Miller \u003cdavem@davemloft.net\u003e\nAcked-by: David S.

This causes\nthe kernel to issue unaligned access warnings on some architectures like\nia64. Unfortunately, some software out there doesn\u0027t properly unroll the\nNLA packet and assumes that the start of the taskstats structure will\nalways be 20 bytes from the start of the netlink payload. Aligning the\nstart of the taskstats structure breaks this software, which we don\u0027t\nwant. So, for now the alignment only happens on architectures that\nrequire it and those users will have to update to fixed versions of those\npackages. Space is reserved in the packet only when needed. This ifdef\nshould be removed in several years e.g. 2012 once we can be confident\nthat fixed versions are installed on most systems. We add the padding\nbefore the aggregate since the aggregate is already a defined type.\n\nCommit 85893120 (\"delayacct: align to 8 byte boundary on 64-bit systems\")\npreviously addressed the alignment issues by padding out the pid field.\nThis was supposed to be a compatible change but the circumstances\ndescribed above mean that it wasn\u0027t. This patch backs out that change,\nsince it was a hack, and introduces a new NULL attribute type to provide\nthe padding. Padding the response with 4 bytes avoids allocating an\naligned taskstats structure and copying it back. Since the structure\nweighs in at 328 bytes, it\u0027s too big to do it on the stack.\n\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nReported-by: Brian Rogers \u003cbrian@xyzw.org\u003e\nCc: Jeff Mahoney \u003cjeffm@suse.com\u003e\nCc: Guillaume Chazarain \u003cguichaz@gmail.com\u003e\nCc: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "b5776c4a6d0afc13697e8452b9ebe1cc4d961b74", "tree": "0b60b679d636a9759849fea1cd36a33438fff5ef", "parents": [ "5e06b6492e53ab2a4e467763a9ee9f70b032c301" ], "author": { "name": "john stultz", "email": "johnstul@us.ibm.com", "time": "Thu Dec 16 19:03:27 2010 +0000" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Wed Dec 22 22:44:43 2010 +0000" }, "message": "Fix rounding in clocks_calc_mult_shift()\n\nRussell King reports:\n| On the ARM dev boards, we have a 32-bit counter running at 24MHz.

Currently, such users need to\nexplicitly flush the workqueue multiple times depending on the\npossible depth of such chained queueing.\n\nThis patch updates the queueing path such that a work item can queue\nfurther work items on the same workqueue even when WQ_DYING is set.\nThe flush on destruction is automatically retried until the workqueue\nis empty. This guarantees that the workqueue is empty on destruction\nwhile allowing chained queueing.\n\nThe flush retry logic whines if it takes too many retries to drain the\nworkqueue.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\n" }, { "commit": "de5e9d58200aafea4a33abcadcd12eb69eaba5c4", "tree": "6f94c2e558772070d283d25a4ba3d9b1738bb95b", "parents": [ "55ec86f848a5f872fd43f5d7206464a0af419110", "050c6c9b896625d9fa498265be17b82c5fc65257" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Dec 20 09:05:26 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Dec 20 09:05:26 2010 -0800" }, "message": "Merge branch \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip\n\n* \u0027sched-fixes-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:\n sched: Remove debugging check\n" }, { "commit": "050c6c9b896625d9fa498265be17b82c5fc65257", "tree": "998a73afe0c3eddd35754cd4de54a65fc4313cec", "parents": [ "8e92c20183ed0579d94501311b81c42b65cb2129" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Dec 19 23:24:27 2010 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Sun Dec 19 23:24:27 2010 +0100" }, "message": "sched: Remove debugging check\n\nLinus reported that the new warning introduced by commit f26f9aff6aaf\n\"Sched: fix skip_clock_update optimization\" triggers.
