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": "4cad6c7c38930618d77e65af82c1403d63879eee", "tree": "9e8c14e0819c42c8ac290f6a0bba5ca45a3ecef2", "parents": [ "f32338319f10c4ca5499c19edc5b3618896920ba" ], "author": { "name": "Sujith", "email": "Sujith.Manoharan@atheros.com", "time": "Wed Feb 10 14:52:21 2010 +0530" }, "committer": { "name": "John W.

As the comment\nindicates, the BUG_ON can be removed since the ampdu_action\ncallback must already exist when the state is !\u003d IDLE.\n\nThe second problem isn\u0027t easily exploitable but there\u0027s a\nrace condition due to unconditionally setting the state to\nOPERATIONAL when a delBA frame is received, even when no\naggregation session was ever initiated. All the drivers\naccept stopping the session even then, but that opens a\nrace window where crashes could happen before the driver\naccepts it. Right now, a WARN_ON may happen with non-HT\ndrivers, while the race opens only for HT drivers.\n\nFor this case, there are two things necessary to fix it:\n 1) don\u0027t process spurious delBA frames, and be more careful\n about the session state; don\u0027t drop the lock\n\n 2) HT drivers need to be prepared to handle a session stop\n even before the session was really started -- this is\n true for all drivers (that support aggregation) but\n iwlwifi which can be fixed easily.

As a first rough\nversion, it actually stops the AC queue for extended periods of time,\nwhich can be removed by adding buffering internal to mac80211, but is\ncurrently not a huge problem because people rarely use multiple TIDs\nthat are in the same AC (and iwlwifi currently doesn\u0027t operate as AP).\n\nThis is a short-term fix, my current medium-term plan, which I hope to\nexecute soon as well, but am not sure can finish before .30, looks like\nthis:\n 1) rework the internal queuing layer in mac80211 that we use for\n fragments if the driver stopped queue in the middle of a fragmented\n frame to be able to queue more frames at once (rather than just a\n single frame with its fragments)\n 2) instead of stopping the entire AC queue, queue up the frames in a\n per-station/per-TID queue during aggregation session initiation,\n when the session has come up take all those frames and put them\n onto the queue from 1)\n 3) push the ampdu queue layer abstraction this patch introduces in\n mac80211 into the driver, and remove the virtual queue stuff from\n mac80211 again\n\nThis plan will probably also affect ath9k in that mac80211 queues the\nframes instead of passing them down, even when there are no ampdu queues.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nSigned-off-by: John W.
