mac80211: call skb_dequeue/ieee80211_free_txskb instead of __skb_queue_purge

2012-11-26T20:14:05Z

commit 1f98ab7fef48a2968f37f422c256c9fbd978c3f0 upstream. Fixes more wifi status skb leaks, leading to hostapd/wpa_supplicant hangs. Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg Signed-off-by: Greg Kroah-Hartman

mac80211: use ieee80211_free_txskb to fix possible skb leaks

2012-10-21T16:32:41Z

commit c3e7724b6bc2f25e46c38dbe68f09d71fafeafb8 upstream. A few places free skbs using dev_kfree_skb even though they're called after ieee80211_subif_start_xmit might have cloned it for tracking tx status. Use ieee80211_free_txskb here to prevent skb leaks.

mac80211: fix DS to MBSS address translation

2012-08-22T07:45:05Z

The destination address of unicast frames forwarded through a mesh gate was being replaced with the broadcast address. Instead leave the original destination address as the mesh DA. If the nexthop address is not in the mpath table it will be resolved. If that fails, the frame will be forwarded to known mesh gates.

mac80211: tx: do not drop non-robust mgmt to non-MFP stas.

2012-07-12T10:10:48Z

When drop_unencrypted is enabled and MFP is disabled, non-robust management frames for not-yet associated STA are dropped. This isn't visible as many management frames sent from the kernel have TX_INTFL_DONT_ENCRYPT set and management frames injected from a monitor vif have TX_CTL_INJECTED so aren't dropped. But management frames sent from userspace via NL80211_CMD_FRAME do not have this flag set, so are dropped. This patch make it always accept non-robust management frames.

mac80211: restructure key selection

2012-07-12T10:10:47Z

The "no key" case in key selection that decides whether to drop the frame or not is impossible to understand, restructure the code. Signed-off-by: Johannes Berg [cavallar@lri.fr: removed blank line and restructured action frame clause] Signed-off-by: Nicolas Cavallari

mac80211: Fix the Problem of Unreachable Mesh STA from DS

2012-07-11T20:24:54Z

This patch fixes the problem of unreachable mesh STA from Distribution System (DS) due to the introduction of previous patch solving the mesh STA joining from one MBSS to another MBSS. Reported-by: Georgiewskiy Yuriy Signed-off-by: Chun-Yeow Yeoh Signed-off-by: John W. Linville

mac80211: fix read outside array bounds

2012-07-10T15:42:52Z

ieee802_1d_to_ac is defined as a const int[8], but the tid parameter has a range from 0 to 15. Cc: stable@vger.kernel.org Signed-off-by: Christian Lamparter Signed-off-by: John W. Linville

mac80211: reduce IEEE80211_TX_MAX_RATES

2012-07-03T11:48:37Z

IEEE80211_TX_MAX_RATES can be reduced from 5 to 4 as there is no current hardware supporting a rate chain with 5 multi rate stages (mrr), so 4 mrr stages are sufficient. The memory that is freed within the ieee80211_tx_info struct will be used in the upcoming Transmission Power Control (TPC) implementation.

mac80211: remove tx_frags driver callback

2012-07-02T13:40:18Z

The implementation of tx_frags is buggy due to not handling queue stop, and there's no driver implementing it so remove it. Signed-off-by: Johannes Berg
