      "message": "ath9k: Group Key fix for VAPs\n\nWhen I set up multiple VAPs with ath9k, I encountered an issue that\nthe traffic may be lost after a while.\n\nThe detailed phenomenon is\n1. After a while the clients connected to one of these VAPs will get\ninto a state that no broadcast/multicast packets can be transfered\nsuccessfully while the unicast packets can be transfered normally.\n2. Minutes latter the unitcast packets transfer will fail as well,\nbecause the ARP entry is expired and it can\u0027t be freshed due to the\nbroadcast trouble.\n\nIt\u0027s caused by the group key overwritten and someone discussed this\nissue in ath9k-devel maillist before, but haven\u0027t work out a fix yet.\n\nI referred the method in madwifi, and made a patch for ath9k.\nThe method is to set the high bit of the sender(AP)\u0027s address, and\nassociated that mac and the group key. It requires the hardware\nsupports multicast frame key search. It seems true for AR9160.\n\nNot sure whether it\u0027s the correct way to fix this issue. But it seems\nto work in my test. The patch is attached, feel free to revise it.\n\nSigned-off-by: Daniel Yingqiang ma \u003cyma.cool@gmail.com\u003e\nSigned-off-by: John W. Linville \u003clinville@tuxdriver.com\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"

Also, key references are rcu-protected\nso we cannot do things atomically.\n\nThis patch changes key locking completely:\n * key operations are now atomic\n * hardware crypto offload is enabled and disabled from\n   a workqueue, due to that key freeing is also delayed\n * debugfs code is also run from a workqueue\n * keys reference STAs (and vice versa!) so during STA\n   unlink the STAs key reference is removed but not the\n   keys STA reference, to avoid races key todo work is\n   run before STA destruction.\n * fewer STA operations now need the RTNL which was\n   required due to key operations\n\nThis fixes the locking problems lockdep pointed out and also\nmakes things more light-weight because the rtnl isn\u0027t required\nas much.\n\nNote that the key todo lock/key mutex are global locks, this\nis not required, of course, they could be per-hardware instead.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nSigned-off-by: John W.

      "message": "[MAC80211]: fix race conditions with keys\n\nDuring receive processing, we select the key long before using it and\nbecause there\u0027s no locking it is possible that we kfree() the key\nafter having selected it but before using it for crypto operations.\nObviously, this is bad.\n\nSecondly, during transmit processing, there are two possible races: We\nhave a similar race between select_key() and using it for encryption,\nbut we also have a race here between select_key() and hardware\nencryption (both when a key is removed.)\n\nThis patch solves these issues by using RCU: when a key is to be freed,\nwe first remove the pointer from the appropriate places (sdata-\u003ekeys,\nsdata-\u003edefault_key, sta-\u003ekey) using rcu_assign_pointer() and then\nsynchronize_rcu(). Then, we can safely kfree() the key and remove it\nfrom the hardware. There\u0027s a window here where the hardware may still\nbe using it for decryption, but we can\u0027t work around that without having\ntwo hardware callbacks, one to disable the key for RX and one to disable\nit for TX; but the worst thing that will happen is that we receive a\npacket decrypted that we don\u0027t find a key for any more and then drop it.\n\nWhen we add a key, we first need to upload it to the hardware and then,\nusing rcu_assign_pointer() again, link it into our structures.\n\nIn the code using keys (TX/RX paths) we use rcu_dereference() to get the\nkey and enclose the whole tx/rx section in a rcu_read_lock() ...\nrcu_read_unlock() block. Because we\u0027ve uploaded the key to hardware\nbefore linking it into internal structures, we can guarantee that it is\nvalid once get to into tx().\n\nOne possible race condition remains, however: when we have hardware\nacceleration enabled and the driver shuts down the queues, we end up\nqueueing the frame. If now somebody removes the key, the key will be\nremoved from hwaccel and then then driver will be asked to encrypt the\nframe with a key index that has been removed. Hence, drivers will need\nto be aware that the hw_key_index they are passed might not be under\nall circumstances. Most drivers will, however, simply ignore that\ncondition and encrypt the frame with the selected key anyway, this\nonly results in a frame being encrypted with a wrong key or dropped\n(rightfully) because the key was not valid. There isn\u0027t much we can\ndo about it unless we want to walk the pending frame queue every time\na key is removed and remove all frames that used it.\n\nThis race condition, however, will most likely be solved once we add\nmultiqueue support to mac80211 because then frames will be queued\nfurther up the stack instead of after being processed.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nAcked-by: Michael Wu \u003cflamingice@sourmilk.net\u003e\nSigned-off-by: John W.

      "message": "[MAC80211]: rework key handling\n\nThis moves all the key handling code out from ieee80211_ioctl.c\ninto key.c and also does the following changes including documentation\nupdates in mac80211.h:\n\n 1) Turn off hardware acceleration for keys when the interface\n    is down. This is necessary because otherwise monitor\n    interfaces could be decrypting frames for other interfaces\n    that are down at the moment. Also, it should go some way\n    towards better suspend/resume support, in any case the\n    routines used here could be used for that as well.\n    Additionally, this makes the driver interface nicer, keys\n    for a specific local MAC address are only ever present\n    while an interface with that MAC address is enabled.\n\n 2) Change driver set_key() callback interface to allow only\n    return values of -ENOSPC, -EOPNOTSUPP and 0, warn on all\n    other return values. This allows debugging the stack when\n    a driver notices it\u0027s handed a key while it is down.\n\n 3) Invert the flag meaning to KEY_FLAG_UPLOADED_TO_HARDWARE.\n\n 4) Remove REMOVE_ALL_KEYS command as it isn\u0027t used nor do we\n    want to use it, we\u0027ll use DISABLE_KEY for each key. It is\n    hard to use REMOVE_ALL_KEYS because we can handle multiple\n    virtual interfaces with different key configuration, so we\u0027d\n    have to keep track of a lot of state for this and that isn\u0027t\n    worth it.\n\n 5) Warn when disabling a key fails, it musn\u0027t.\n\n 6) Remove IEEE80211_HW_NO_TKIP_WMM_HWACCEL in favour of per-key\n    IEEE80211_KEY_FLAG_WMM_STA to let driver sort it out itself.\n\n 7) Tell driver that a (non-WEP) key is used only for transmission\n    by using an all-zeroes station MAC address when configuring.\n\n 8) Change the set_key() callback to have access to the local MAC\n    address the key is being added for.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nAcked-by: Michael Wu \u003cflamingice@sourmilk.net\u003e\nSigned-off-by: John W.

      "message": "[MAC80211]: embed key conf in key, fix driver interface\n\nThis patch embeds the struct ieee80211_key_conf into struct ieee80211_key\nand thus avoids allocations and having data present twice.\n\nThis required some more changes:\n 1) The removal of the IEEE80211_KEY_DEFAULT_TX_KEY key flag.\n    This flag isn\u0027t used by drivers nor should it be since\n    we have a set_key_idx() callback. Maybe that callback needs\n    to be extended to include the key conf, but only a driver that\n    requires it will tell.\n 2) The removal of the IEEE80211_KEY_DEFAULT_WEP_ONLY key flag.\n    This flag is global, so it shouldn\u0027t be passed in the key\n    conf structure. Pass it to the function instead.\n\nAlso, this patch removes the AID parameter to the set_key() callback\nbecause it is currently unused and the hardware currently cannot know\nabout the AID anyway. I suspect this was used with some hardware that\nactually selected the AID itself, but that functionality was removed.\n\nAdditionally, I\u0027ve removed the ALG_NULL key algorithm since we have\nALG_NONE.\n\nSigned-off-by: Johannes Berg \u003cjohannes@sipsolutions.net\u003e\nAcked-by: Michael Wu \u003cflamingice@sourmilk.net\u003e\nSigned-off-by: John W.
