Powersave looks like it got broken at some point but we'll fix that up when the command submission stuff is more understandable, which this series helps to do. That said, this patch should not further break powersave. Signed-off-by:

Slightly different approach here since there are so many arguments to the firmware command. Just let the caller fill them in before pushing the command to the firmware. Signed-off-by:

For now; it's a pretty easy command to hook up and whenever OLPC figures out how they want the userspace interface to look (ie, not iwpriv commands) we can easily add it back in. Since the cfg80211 conversion it wasn't working anyway. Signed-off-by:

On our hardware (050d:7050 Belkin Components F5D7050 Wireless G Adapter), setting any WEP key with non zero index, cause rx frames corruption. Note: perhaps (I did not check) this can be fixed differently - by using hw_key_idx the same as true MAC key index. But according to the comment in rt2x00mac_set_key(): "the hardware requires keys to be assigned in correct order (When key 1 is provided but key 0 is not, then the key is not found by the hardware during RX)" this will be quite problematic. Since WEP should not be used, disabling hardware crypto offload for it will not hurt much. Beside static one key WEP will still be offloaded. Signed-off-by:

The user ratekbs of MCS15 ShortGI is incorrect and can not be lesser than MCS15 rate. This incorrect rate may affect switching to higher rates as the rate control algorithm always finds MCS15 is better than MCS15 ShortGI and results in lower throughput. Fix this by feeding the correct user ratekbs for MCS15 ShortGI rate. This issue affects 3 stream case very badly as the 3 stream rates are not used at all once we scale down to MCS15 from 3 stream rates. Signed-off-by:

replace valid and valid_single_stream in rate table with bit masks and reorganize the code so adding 3x3 rate control would be easier. Signed-off-by:

Key locking simplification removed key->sdata != NULL verification from ieee80211_key_free(). While that is fine for most use cases, there is one path where this function can be called with an unlinked key (i.e., key->sdata == NULL && key->local == NULL). This results in a NULL pointer dereference with the current implementation. This is known to happen at least with FT protocol when wpa_supplicant tries to configure the key before association. Avoid the issue by passing in the local pointer to ieee80211_key_free(). In addition, do not clear the key from hw_accel or debugfs if it has not yet been added. At least the hw_accel one could trigger another NULL pointer dereference. Signed-off-by:

In AP mode, there is no need to notify the driver about QoS changes for the monitor interface that is created. The warning in ieee80211_bss_info_change_notify() would be hit otherwise. Signed-off-by:

The noisefloor array index always corresponds to the rx chain number it belongs to (with an offset of 3 for the extension chain). It's much simpler (and actually more correct) to directly use the chainmask to calculate the bitmask for the noisefloor array, instead of using these weird chip revision checks and hardcoded mask values.

When the hardware is configured in HT20 mode, noise floor readings for the extension channel often return invalid values, which keep the values in the NF history buffer at the hardware-specific maximum limit. Fix this by discarding the extension channel values when in HT20 mode. Signed-off-by:

When an aggregation session is being cleaned up, while the tx status for some frames is being processed, the TID is flushed and its buffers are sent out. Unfortunately that left the pending un-acked frames unprocessed, thus leaking buffers. Fix this by reordering the code so that those frames are processed first, before the TID is flushed.

I just had the following: WARNING: at drivers/net/wireless/iwlwifi/iwl-agn-tx.c:574 iwlagn_tx_skb+0x1576/0x15f0 [iwlagn]() Call Trace: <IRQ> [<ffffffff8105c5df>] warn_slowpath_common+0x7f/0xc0 [<ffffffff8105c63a>] warn_slowpath_null+0x1a/0x20 [<ffffffffa0290b46>] iwlagn_tx_skb+0x1576/0x15f0 [iwlagn] [<ffffffffa027076c>] iwl_mac_tx+0x5c/0x260 [iwlagn] [<ffffffffa01bdf5b>] __ieee80211_tx+0x10b/0x1a0 [mac80211] [<ffffffffa01bfb86>] ieee80211_tx_pending+0x186/0x2d0 [mac80211] [<ffffffff81062ea5>] tasklet_action+0x125/0x130 [<ffffffff810634a6>] __do_softirq+0x106/0x270 [<ffffffff8100c09c>] call_softirq+0x1c/0x30 iwlagn 0000:02:00.0: Attempting to modify non-existing station 107 Note that 107 == 0x6b which is slab poison. The reason is that mac80211 passed a freed station pointer to mac80211, because as it happened iwlwifi reset itself while mac80211 was disconnecting from the network. It turns out that we do take care to look up the station pointer in ieee80211_tx_pending_skb, but then don't use it, which obviously is a bug. Fix this by removing the ieee80211_tx_h_sta handler and assigning the station pointer directly. Signed-off-by:

Use kmemdup when some other buffer is immediately copied into the allocated region. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...)
