      "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.

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.
