Many places also simply do\n\n  return nlmsg_end(...);\n\nand the caller is expected to deal with it.\n\nThis also commonly (at least for me) causes errors, because it is very\ncommon to write\n\n  if (my_function(...))\n    /* error condition */\n\nand if my_function() does \"return nlmsg_end()\" this is of course wrong.\n\nAdditionally, there\u0027s not a single place in the kernel that actually\nneeds the message length returned, and if anyone needs it later then\nit\u0027ll be very easy to just use skb-\u003elen there.\n\nRemove this, and make the functions void. This removes a bunch of dead\ncode as described above. The patch adds lines because I did\n\n-\treturn nlmsg_end(...);\n+\tnlmsg_end(...);\n+\treturn 0;\n\nI could have preserved all the function\u0027s return values by returning\nskb-\u003elen, but instead I\u0027ve audited all the places calling the affected\nfunctions and found that none cared. A few places actually compared\nthe return value with \u003c\u003d 0 in dump functionality, but that could just\nbe changed to \u003c 0 with no change in behaviour, so I opted for the more\nefficient version.\n\nOne instance of the error I\u0027ve made numerous times now is also present\nin net/phonet/pn_netlink.c in the route_dumpit() function - it didn\u0027t\ncheck for \u003c0 or \u003c\u003d0 and thus broke out of the loop every single time.\nI\u0027ve preserved this since it will (I think) have caused the messages to\nuserspace to be formatted differently with just a single message for\nevery SKB returned to userspace. It\u0027s possible that this isn\u0027t needed\nfor the tools that actually use this, but I don\u0027t even know what they\nare so couldn\u0027t test that changing this behaviour would be acceptable.\n\nSigned-off-by: Johannes Berg \u003cjohannes.berg@intel.com\u003e\nSigned-off-by: David S.

      "message": "taskstats: use better ifdef for alignment\n\nCommit 4be2c95d (\"taskstats: pad taskstats netlink response for aligment\nissues on ia64\") added a null field to align the taskstats structure but\nthe discussion centered around ia64.  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.

      "message": "taskstats: pad taskstats netlink response for aligment issues on ia64\n\nThe taskstats structure is internally aligned on 8 byte boundaries but the\nlayout of the aggregrate reply, with two NLA headers and the pid (each 4\nbytes), actually force the entire structure to be unaligned.  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"

      "message": "include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h\n\npercpu.h is included by sched.h and module.h and thus ends up being\nincluded when building most .c files.  percpu.h includes slab.h which\nin turn includes gfp.h making everything defined by the two files\nuniversally available and complicating inclusion dependencies.\n\npercpu.h -\u003e slab.h dependency is about to be removed.  Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability.  As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n  http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n  only the necessary includes are there.  ie. if only gfp is used,\n  gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n  blocks and try to put the new include such that its order conforms\n  to its surrounding.  It\u0027s put in the include block which contains\n  core kernel includes, in the same order that the rest are ordered -\n  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n  doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n  because the file doesn\u0027t have fitting include block), it prints out\n  an error message indicating which .h file needs to be added to the\n  file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n   over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n   and ~3000 slab.h inclusions.  The script emitted errors for ~400\n   files.\n\n2. Each error was manually checked.  Some didn\u0027t need the inclusion,\n   some needed manual addition while adding it to implementation .h or\n   embedding .c file was more appropriate for others.  This step added\n   inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n   from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n   e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n   APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n   editing them as sprinkling gfp.h and slab.h inclusions around .h\n   files could easily lead to inclusion dependency hell.  Most gfp.h\n   inclusion directives were ignored as stuff from gfp.h was usually\n   wildly available and often used in preprocessor macros.  Each\n   slab.h inclusion directive was examined and added manually as\n   necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my\n   distributed build env didn\u0027t work with gcov compiles) and a few\n   more options had to be turned off depending on archs to make things\n   build (like ipr on powerpc/64 which failed due to missing writeq).\n\n   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n   * powerpc and powerpc64 SMP allmodconfig\n   * sparc and sparc64 SMP allmodconfig\n   * ia64 SMP allmodconfig\n   * s390 SMP allmodconfig\n   * alpha SMP allmodconfig\n   * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n   a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n"

      "message": "Add cgroupstats\n\nThis patch is inspired by the discussion at\nhttp://lkml.org/lkml/2007/4/11/187 and implements per cgroup statistics\nas suggested by Andrew Morton in http://lkml.org/lkml/2007/4/11/263.  The\npatch is on top of 2.6.21-mm1 with Paul\u0027s cgroups v9 patches (forward\nported)\n\nThis patch implements per cgroup statistics infrastructure and re-uses\ncode from the taskstats interface.  A new set of cgroup operations are\nregistered with commands and attributes.  It should be very easy to\n*extend* per cgroup statistics, by adding members to the cgroupstats\nstructure.\n\nThe current model for cgroupstats is a pull, a push model (to post\nstatistics on interesting events), should be very easy to add.  Currently\nuser space requests for statistics by passing the cgroup file\ndescriptor.  Statistics about the state of all the tasks in the cgroup\nis returned to user space.\n\nTODO\u0027s/NOTE:\n\nThis patch provides an infrastructure for implementing cgroup statistics.\nBased on the needs of each controller, we can incrementally add more statistics,\nevent based support for notification of statistics, accumulation of taskstats\ninto cgroup statistics in the future.\n\nSample output\n\n# ./cgroupstats -C /cgroup/a\nsleeping 2, blocked 0, running 1, stopped 0, uninterruptible 0\n\n# ./cgroupstats -C /cgroup/\nsleeping 154, blocked 0, running 0, stopped 0, uninterruptible 0\n\nIf the approach looks good, I\u0027ll enhance and post the user space utility for\nthe same\n\nFeedback, comments, test results are always welcome!\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Balbir Singh \u003cbalbir@linux.vnet.ibm.com\u003e\nCc: Paul Menage \u003cmenage@google.com\u003e\nCc: Jay Lan \u003cjlan@engr.sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
