2009-02-11iwlwifi: fix suspend/resume and its usage of pci saved stateReinette Chatre
Here we do two things: First, revert "iwlwifi: save PCI state before suspend, restore after resume". That misguided patch led to being unable to use iwlwifi devices after resume. Next, indicate to PCI driver that the saved PCI state is valid during suspend. We restore PCI state and enable the device when network interface is created, similarly PCI state is saved and the device is disabled when network interface is removed. Thus, when .suspend is called the PCI state is saved and device is disabled. This is the case even if an interface is never created as PCI state is saved and device disabled during .probe. PCI driver assumes PCI state is saved in .suspend. Saving the state at this time will save state of disabled device and thus cause problems during resume (resuming a disabled device). We thus indicate directly to PCI driver that current PCI saved state is valid.

2009-02-11ath5k: fix bf->skb==NULL panic in ath5k_tasklet_rxBob Copeland
Under memory pressure, we may not be able to allocate a new skb for new packets. If the allocation fails, ath5k_tasklet_rx will exit but will leave a buffer in the list with a NULL skb, eventually triggering a BUG_ON. Extract the skb allocation from ath5k_rxbuf_setup() and change the tasklet to allocate the next skb before accepting a packet.

A difference was found in the code used to index the OFDM power tables. When the Linux driver was changed, my unit works at a much greater range than before.

However Artur Skawina <art.08.09@gmail.com> has shown that it can happen in reverse order as well. This is very bad and could lead to memory corruptions, oopses and panics.

Mac80211 provides 2 structures to handle bitrates, namely ieee80211_rate and ieee80211_tx_rate. To determine the short preamble mode for an outgoing frame, the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE must be checked on ieee80211_tx_rate and not ieee80211_rate (which rt2x00 did).

2009-01-16rt2x00: fix a wrong parameter for __test_and_clear_bit() in rt2x00rfkill_free().Rami Rosen
When running modprobe rt73usb, and then rmmod rt73usb, and then iwconfig, the wlan0 device does not disappear. When repeating this process again, we get a kernel Oops errors and "BUG: unable to handle kernel paging request..." message in the kernel log. The reason for this is that there is an error in rt2x00rfkill_free(), which is called in the process of removing the device (rt2x00lib_remove_dev() in rt2x00dev.c). rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is bit number 1 () in rt2x00dev->flags instead of in rt2x00dev->rfkill_state. As a result, when checking the DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call ieee80211_unregister_hw(). This patch corrects this: the parameter for __test_and_clear_bit() in rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not &rt2x00dev->flags.

2009-01-16iwlwifi: remove CMD_WANT_SKB flag if send_cmd_sync failureZhu Yi
In function iwl_send_cmd_sync(), if the flag CMD_WANT_SKB is set but we are not provided with a valid SKB (cmd->meta.u.skb == NULL), we need to remove the CMD_WANT_SKB flag from the TX cmd queue. Otherwise in case the cmd comes in later, it will possibly set an invalid address. Thus it causes an invalid memory access. This fixed the bug http://bugzilla.kernel.org/show_bug.cgi?id=11326.

2009-01-12rt2x00: Fix rt2500usb HW crypto: WEP 128 & AESIvo van Doorn
The TXD_W0_CIPHER field is a 1-bit field. It only acts as boolean value to indicate if the frame must be encrypted or not. The way rt2x00_set_field32() worked it would grab the least signifcant bit from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP worked since they had odd-numbered values, while WEP 128 and AES were even numbers and didn't work. Correctly booleanize the txdecs->cipher value to allow the hardware to encrypt the outgoing data. After this we can enable HW crypto by default again.

2009-01-12ath9k: Revert fix to TX status reporting for retries and MCS indexJouni Malinen
This patch reverts "ath9k: Fix TX status reporting for retries and MCS index" because that change ended up breaking ath9k rate control. While the MCS index reporting to mac80211 was indeed fixed by the patch, it did not take into account that the ath9k rate control algorithm was updating private tables based on this index and the index comes through the rate control API call, i.e., based on mac80211 TX status call. In addition, it looks like the "fix" to remove +1 from TX status 'count' field was not correct based on ieee80211_tx_status() implementation that counts the total of count values, but starting from -1, not 0. The TX status reporting for frames using MCS needs to be fixed somehow, but it does not look like there is any easy fix for the ath9k rate control algorithm, so the best option now seems to be to revert the change and bring it back once the rate control code is cleaned up to handle this better.
