Reason of the panic is that list_first_entry() is blindly called in macvlan_handle_frame() even if the list was empty. vlan is set to incorrect pointer which leads to the crash. I'm fixing this by protecting port->vlans list by rcu and by preventing from getting incorrect pointer in case the list is empty.

| * mwifiex: fix setting of multicast filterDaniel Drake2013-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A small bug in this code was causing the ALLMULTI filter to be set when in fact we were just wanting to program a selective multicast list to the hardware. Fix that bug and remove a redundant if condition in the code that follows. This fixes wakeup behaviour when multicast WOL is enabled. Previously, all multicast packets would wake up the system. Now, only those that the host intended to receive trigger wakeups.

The error is hit within an hour or two. This issue happens when an interrupt comes in early while host sleep is still activated. Driver handles this case by auto cancelling host sleep. However is_suspended flag is still set which prevents any cmd or data from being sent to firmware. Fix it by clearing is_suspended flag in this path.

| * iwl4965: workaround connection regression on passive channelStanislaw Gruszka2013-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Jake reported that since commit 1672c0e31917f49d31d30d79067103432bc20cc7 "mac80211: start auth/assoc timeout on frame status", he is unable to connect to his AP, which is configured to use passive channel. After switch to passive channel 4965 firmware drops any TX packet until it receives beacon. Before commit 1672c0e3 we waited on channel and retransmit packet after 200ms, that makes we receive beacon on the meantime and association process succeed. New mac80211 behaviour cause that any ASSOC frame fail immediately on iwl4965 and we can not associate. This patch restore old mac80211 behaviour for iwl4965, by removing IEEE80211_HW_REPORTS_TX_ACK_STATUS feature. This feature will be added again to iwl4965 driver, when different, more complex workaround for this firmware issue, will be added to the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add handling of rx descriptor underflow. This fixes a fault that could happen on slow machines, where data is received faster than the CPU can handle. In such a case the device will use up all rx descriptors and refuse to send any more data before confirming that it is ok. This patch enables necessary interrupt to discover such a situation and will handle them by dropping everything in the ring buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch claim to fix "WARNING: at net/mac80211/util.c:599 ieee80211_can_queue_work.isra.7+0x30/0x40", which was reported at: https://bugzilla.redhat.com/show_bug.cgi?id=922295 We use ATH_STAT_STARTED flag to disallow to perform ath5k_tx_complete_poll_work() code, hence reschedule ah->tx_complete_work, when we stop device. This flag was defined in ath5k code, but it was not used. I didn't get feedback if the fix works, so patch is compile only tested.

| | | | | | | | | | | | | | | | | | | | | | | | If no keycache slots are available, ath_key_config can return -ENOSPC. If the key index is not checked for errors, it can lead to logspam that looks like this: "ath: wiphy0: keyreset: keycache entry 228 out of range" This can cause follow-up errors if the invalid keycache index gets used for tx.

| * | tile: support new Tilera hypervisorChris Metcalf2013-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tilera hypervisor shipped in releases up through MDE 4.1 launches the client operating system (i.e. Linux) at privilege level 1 (PL1). Starting with MDE 4.2, as part of the work to enable KVM, the Tilera hypervisor launches Linux at PL2 instead. This commit makes the KERNEL_PL option default to 2 for tilegx, while still saying at 1 for tilepro, which doesn't have an updated hypervisor. It also explains how and when you might want to choose another value. In addition, we change a small buglet in the on-chip Ethernet driver, where we were failing to use the KERNEL_PL constant in an API call. To make the transition cleaner, this change also provides the updated hv_init() API for the new hypervisor that supports announcing Linux's compiled-in PL, so the hypervisor can generate a suitable error in the case of a mismatched hypervisor and Linux binary.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver and firmware sync up through SYNC messages, and the firmware's affirmative reply to these SYNC messages appears to be the "Reset" indication received via the status interrupt endpoint. Thus the driver needs the status interrupt endpoint always active so that the Reset indication can be received even if the netdev is closed, which is the case right after device insertion. If the Reset indication is not received by the driver, it continues sending SYNC messages to the firmware, which crashes about 10 seconds later and the device stops responding.

Add functions to refcount the status interrupt URB submit/kill operation so that sub-drivers and the generic driver don't fight over whether the status interrupt URB is active or not. A sub-driver can call usbnet_status_start() at any time, but the URB is only submitted the first time the function is called. Likewise, when the sub-driver is done with the URB, it calls usbnet_status_stop() but the URB is only killed when all users have stopped it. The URB is still killed and re-submitted for suspend/resume, as before, with the same refcount it had at suspend.

Each CQ-notify with rearm can result in an event. The EQ may get full resulting in a HW error. Fix this by not re-arming the CQ while notifying a valid completion. Also, there's no need to wait for 1ms after destroying RXQ, as the code in be_rx_cq_clean() waits for the flush compl to arrive.
