b43: Fix Bugzilla #14181 and the bug from the previous 'fix'

2009-11-10T00:51:53Z

commit d50bae33d1358b909ade05ae121d83d3a60ab63f upstream. "b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported in Bugzilla No. 14181; however, it introduced a new bug. Whenever the radio switch was turned off, it was necessary to unload and reload the driver for it to recognize the switch again. This patch fixes both the original bug in #14181 and the bug introduced by the previous patch. It must be stated, however, that if there is a BCM4306/3 with an rfkill switch (not yet proven), then the driver will need an unload/reload cycle to turn the device back on.

b43: Refresh RX poison on buffer recycling

2009-05-08T21:54:34Z

upstream commit: cf68636a9773aa97915497fe54fa4a51e3f08f3a The RX buffer poison needs to be refreshed, if we recycle an RX buffer, because it might be (partially) overwritten by some DMA operations.

b43: Poison RX buffers

2009-05-08T21:54:34Z

upstream commit: ec9a1d8c13e36440eda0f3c79b8149080e3ab5ba This patch adds poisoning and sanity checking to the RX DMA buffers. This is used for protection against buggy hardware/firmware that raises RX interrupts without doing an actual DMA transfer. This mechanism protects against rare "bad packets" (due to uninitialized skb data) and rare kernel crashes due to uninitialized RX headers. The poison is selected to not match on valid frames and to be cheap for checking. The poison check mechanism _might_ trigger incorrectly, if we are voluntarily receiving frames with bad PLCP headers. However, this is nonfatal, because the chance of such a match is basically zero and in case it happens it just results in dropping the packet. Bad-PLCP RX defaults to off, and you should leave it off unless you want to listen to the latest news broadcasted by your microwave oven. This patch also moves the initialization of the RX-header "length" field in front of the mapping of the DMA buffer. The CPU should not touch the buffer after we mapped it.

b43: fix b43_plcp_get_bitrate_idx_ofdm return type

2009-05-02T17:23:33Z

upstream commit: a3c0b87c4f21911fb7185902dd13f0e3cd7f33f7 This patch fixes the return type of b43_plcp_get_bitrate_idx_ofdm. If the plcp contains an error, the function return value is 255 instead of -1, and the packet was not dropped. This causes a warning in __ieee80211_rx function because rate idx is out of range.

Revert "b43/b43legacy: add RFKILL_STATE_HARD_BLOCKED support"

This reverts commit bc19d6e0b74ef03a3baf035412c95192b54dfc6f, which as Larry Finger reports causes the radio LED on his system to no longer respond to rfkill switch events. Reported-by: Larry Finger Requested-by: John W. Linville Signed-off-by: Linus Torvalds

b43: Fix for another Bluetooth Coexistence SPROM Programming error for BCM4306

2008-08-18T15:05:15Z

In trying to help users on the Ubuntu Bugzilla, I discovered another BCM4306 with the Bluetooth Coexistence programming error in the SPROM. This patch is contingent on the one that added the Linksys device with subdevice code of 0x0014. Signed-off-by: Larry Finger Cc: Stable Signed-off-by: John W. Linville

mac80211: partially fix skb->cb use

2008-07-29T20:55:08Z

This patch fixes mac80211 to not use the skb->cb over the queue step from virtual interfaces to the master. The patch also, for now, disables aggregation because that would still require requeuing, will fix that in a separate patch. There are two other places (software requeue and powersaving stations) where requeue can happen, but that is not currently used by any drivers/not possible to use respectively.
