2012-07-09iwlegacy: don't mess up the SCD when removing a keyEmmanuel Grumbach
When we remove a key, we put a key index which was supposed to tell the fw that we are actually removing the key. But instead the fw took that index as a valid index and messed up the SRAM of the device. This memory corruption on the device mangled the data of the SCD. The impact on the user is that SCD queue 2 got stuck after having removed keys.

2012-04-10mac80211: remove antenna_sel_tx TX info fieldJohannes Berg
This field is never set to anything non-zero in mac80211, so we should be able to remove it. Unfortunately though, the iwlwifi and iwlegacy drivers use it for their internal TX status processing (which shouldn't be using the rate control API to start with), so add a new field "status.antenna" for them, at least for now. In the future, I plan to use the new field to hold the hardware queue, while the SKB's queue mapping holds the AC. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2012-03-26iwlegacy: do not nulify il->vif on resetStanislaw Gruszka
This il->vif is dereferenced in different part of iwlegacy code, so do not nullify it. This should fix random crashes observed in companion with microcode errors i.e. crash in il3945_config_ap(). Additionally this should address also WARNING: at drivers/net/wireless/iwlegacy/common.c:4656 il_mac_remove_interface at least one of the possible reasons of that warning.

2012-03-25net: add a truesize parameter to skb_add_rx_frag()Eric Dumazet
skb_add_rx_frag() API is misleading. Network skbs built with this helper can use uncharged kernel memory and eventually stress/crash machine in OOM.

2012-02-29iwlegacy: remove enum iw_calib and related codeGreg Dietsche
Remove the enum il_calib. It defined one identifier: IL_CALIB_MAX. Remove the function il4965_calib_free_results. It was doing nothing because IL_CALIB_MAX is zero. Next, remove calib_results from the il_priv structure and also remove the associated return type/struct il_calib_result. Signed-off-by: Greg Dietsche <Gregory.Dietsche@cuw.edu> Signed-off-by: John W.

2012-02-29mac80211: handle non-bufferable MMPDUs correctlyJohannes Berg
This renames the IEEE80211_TX_CTL_POLL_RESPONSE TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also uses it for non-bufferable MMPDUs (all MMPDUs but deauth, disassoc and action frames.) Previously, mac80211 would let the MMPDU through but not set the flag so drivers supporting some hardware aids for avoiding the PS races would then reject the frame.
