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" }, { "commit": "66aa4a55fe0548c8b13a195c61774db65c5896cd", "tree": "d689361c310ae55678f9fbd73b8d2d273f830ecc", "parents": [ "5c58c47a4f3758c81594402451d8fe0d8accb4e8" ], "author": { "name": "Tom Goff", "email": "thomas.goff@boeing.com", "time": "Fri Mar 19 15:38:50 2010 +0000" }, "committer": { "name": "David S.

Thus, currently 32-bit tasks on 64-bit platforms\ncannot properly receive events and fail with all kinds of\nstrange problems, for instance wpa_supplicant never notices\ndisassociations, due to the way the 64-bit event looks (to a\n32-bit process), the fact that the address is all zeroes is\nlost, it thinks instead it is 00:00:00:00:01:00.\n\nThe same problem existed with the ioctls, until David Miller\nfixed those some time ago in an heroic effort.\n\nA different problem caused by this is that we cannot send the\nASSOCREQIE/ASSOCRESPIE events because sending them causes a\n32-bit wpa_supplicant on a 64-bit system to overwrite its\ninternal information, which is worse than it not getting the\ninformation at all -- so we currently resort to sending a\ncustom string event that it then parses. This, however, has a\nsevere size limitation we are frequently hitting with modern\naccess points; this limitation would can be lifted after this\npatch by sending the correct binary, not custom, event.\n\nA similar problem apparently happens for some other netlink\nusers on x86_64 with 32-bit tasks due to the alignment for\n64-bit quantities.\n\nIn order to fix these problems, I have implemented a way to\nsend compat messages to tasks. When sending an event, we send\nthe non-compat event data together with a compat event data in\nskb_shinfo(main_skb)-\u003efrag_list. Then, when the event is read\nfrom the socket, the netlink code makes sure to pass out only\nthe skb that is compatible with the task. This approach was\nsuggested by David Miller, my original approach required\nalways sending two skbs but that had various small problems.\n\nTo determine whether compat is needed or not, I have used the\nMSG_CMSG_COMPAT flag, and adjusted the call path for recv and\nrecvfrom to include it, even if those calls do not have a cmsg\nparameter.\n\nI have not solved one small part of the problem, and I don\u0027t\nthink it is necessary to: if a 32-bit application uses read()\nrather than any form of recvmsg() it will still get the wrong\n(64-bit) event. However, neither do applications actually do\nthis, nor would it be a regression.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nSigned-off-by: David S.

This flag can\nbe used by unicast and broadcast listeners to avoid receiving\nENOBUFS errors.\n\nGenerally speaking, ENOBUFS errors are useful to notify two things\nto the listener:\n\na) You may increase the receiver buffer size via setsockopt().\nb) You have lost messages, you may be out of sync.\n\nIn some cases, ignoring ENOBUFS errors can be useful. For example:\n\na) nfnetlink_queue: this subsystem does not have any sort of resync\nmethod and you can decide to ignore ENOBUFS once you have set a\ngiven buffer size.\n\nb) ctnetlink: you can use this together with the socket flag\nNETLINK_BROADCAST_SEND_ERROR to stop getting ENOBUFS errors as\nyou do not need to resync (packets whose event are not delivered\nare drop to provide reliable logging and state-synchronization).\n\nMoreover, the use of NETLINK_NO_ENOBUFS also reduces a \"go up, go down\"\neffect in terms of performance which is due to the netlink congestion\ncontrol when the listener cannot back off. The effect is the following:\n\n1) throughput rate goes up and netlink messages are inserted in the\nreceiver buffer.\n2) Then, netlink buffer fills and overruns (set on nlk-\u003estate bit 0).\n3) While the listener empties the receiver buffer, netlink keeps\ndropping messages. Thus, throughput goes dramatically down.\n4) Then, once the listener has emptied the buffer (nlk-\u003estate\nbit 0 is set off), goto step 1.\n\nThis effect is easy to trigger with netlink broadcast under heavy\nload, and it is more noticeable when using a big receiver buffer.\nYou can find some results in [1] that show this problem.\n\n[1] http://1984.lsi.us.es/linux/netlink/\n\nThis patch also includes the use of sk_drop to account the number of\nnetlink messages drop due to overrun.
