Panic happened because we eat 4 bytes of skb headroom on each
(re)transmission when sending frame without the payload and the header
length not being multiple of 4 (i.e. QoS header has 26 bytes). On such
case because paylad_aling=2 is bigger than header_align=0 we increase
header_align by 4 bytes. To prevent that we could change the check to:

	if (payload_length && payload_align > header_align)
		header_align += 4;

but not aligning payload at all is more effective and alignment is not
really needed by H/W (that has been tested on OpenWrt project for few

ath9k: Fix RTC_DERIVED_CLK usage 2014-12-06T23:55:35+00:00 Miaoqing Pan miaoqing@qca.qualcomm.com 2014-11-06T05:22:23+00:00 ad0ef9e8b8432bc4af8cf87a68e92a6b5bca53ef commit 4e6ce4dc7ce71d0886908d55129d5d6482a27ff9 upstream. Based on the reference clock, which could be 25MHz or 40MHz, AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550. But, when a chip reset is done, processing the initvals sets the register back to the default value. Fix this by moving the code in ath9k_hw_init_pll() to ar9003_hw_override_ini().

commit 805dbe17d1c832ad341f14fae8cedf41b67ca6fa upstream.

The driver is not released when ieee80211_register_hw fails in
mac80211_hwsim_create_radio, leading to the access to the unregistered (and
possibly freed) device in platform_driver_unregister:

Revert "iwlwifi: mvm: treat EAPOLs like mgmt frames wrt rate" 2014-11-14T17:00:09+00:00 Emmanuel Grumbach emmanuel.grumbach@intel.com 2014-10-20T05:29:55+00:00 70f08e0880b59a09b7320d3caa7788610c6a45ca commit 1ffde699aae127e7abdb98dbdedc2cc6a973a1a1 upstream. This reverts commit aa11bbf3df026d6b1c6b528bef634fd9de7c2619. This commit was causing connection issues and is not needed if IWL_MVM_RS_RSSI_BASED_INIT_RATE is set to false by default. Regardless of the issues mentioned above, this patch added the following WARNING: WARNING: CPU: 0 PID: 3946 at drivers/net/wireless/iwlwifi/mvm/tx.c:190 iwl_mvm_set_tx_params+0x60a/0x6f0 [iwlmvm]() Got an HT rate for a non data frame 0x8 CPU: 0 PID: 3946 Comm: wpa_supplicant Tainted: G O 3.17.0+ #6 Hardware name: LENOVO 20ANCTO1WW/20ANCTO1WW, BIOS GLET71WW (2.25 ) 07/02/2014 0000000000000009 ffffffff814fa911 ffff8804288db8f8 ffffffff81064f52 0000000000001808 ffff8804288db948 ffff88040add8660 ffff8804291b5600 0000000000000000 ffffffff81064fb7 ffffffffa07b73d0 0000000000000020 Call Trace: [<ffffffff814fa911>] ? dump_stack+0x41/0x51 [<ffffffff81064f52>] ? warn_slowpath_common+0x72/0x90 [<ffffffff81064fb7>] ? warn_slowpath_fmt+0x47/0x50 [<ffffffffa07a39ea>] ? iwl_mvm_set_tx_params+0x60a/0x6f0 [iwlmvm] [<ffffffffa07a3cf8>] ? iwl_mvm_tx_skb+0x48/0x3c0 [iwlmvm] [<ffffffffa079cb9b>] ? iwl_mvm_mac_tx+0x7b/0x180 [iwlmvm] [<ffffffffa0746ce9>] ? __ieee80211_tx+0x2b9/0x3c0 [mac80211] [<ffffffffa07492f3>] ? ieee80211_tx+0xb3/0x100 [mac80211] [<ffffffffa0749c49>] ? ieee80211_subif_start_xmit+0x459/0xca0 [mac80211] [<ffffffff814116e7>] ? dev_hard_start_xmit+0x337/0x5f0 [<ffffffff81430d46>] ? sch_direct_xmit+0x96/0x1f0 [<ffffffff81411ba3>] ? __dev_queue_xmit+0x203/0x4f0 [<ffffffff8142f670>] ? ether_setup+0x70/0x70 [<ffffffff814e96a1>] ? packet_sendmsg+0xf81/0x1110 [<ffffffff8140625c>] ? skb_free_datagram+0xc/0x40 [<ffffffff813f7538>] ? sock_sendmsg+0x88/0xc0 [<ffffffff813f7274>] ? move_addr_to_kernel.part.20+0x14/0x60 [<ffffffff811c47c2>] ? __inode_wait_for_writeback+0x62/0xb0 [<ffffffff813f7a91>] ?
