2009-12-21ath9k: Fix TX queue drainingSujith
When TX DMA termination has failed, the HW has to be reset completely. Doing a fast channel change in this case is insufficient. Also, change the debug level of a couple of messages to FATAL.

2009-12-21iwlwifi: fix more eeprom endian bugsJohannes Berg
I've also for a long time had a problem with the temperature calculation code, which I had fixed by byte-swapping the values, and now it turns out that was the correct fix after all. Also, any use of iwl_eeprom_query_addr() that is for more than a u8 must be cast to little endian, and some structs as well. Fix all this. Again, no real impact on platforms that already are little endian.

2009-12-21iwlwifi: fix EEPROM/OTP reading endian annotations and a bugJohannes Berg
The construct "le16_to_cpu((__force __le16)(r >> 16))" has always bothered me when looking through the iwlwifi code, it shouldn't be necessary to __force anything, and before this code, "r" was obtained with an ioread32, which swaps each of the two u16 values in it properly when swapping the entire u32 value. I've had arguments about this code with people before, but always conceded they were right because removing it only made things not work at all on big endian platforms. However, analysing a failure of the OTP reading code, I now finally figured out what is going on, and why my intuition about that code being wrong was right all along. It turns out that the 'priv->eeprom' u8 array really wants to have the data in it in little endian. So the force code above and all really converts *to* little endian, not from it. Cf., for instance, the function iwl_eeprom_query16() -- it reads two u8 values and combines them into a u16, in a little-endian way. And considering it more, it makes sense to have the eeprom array as on the device, after all not all values really are 16-bit values, the MAC address for instance is not. Now, what this really means is that all the annotations are completely wrong. The eeprom reading code should fill the priv->eeprom array as a __le16 array, with __le16 values. This also means that iwl_read_otp_word() should really have a __le16 pointer as the data argument, since it should be filling that in a format suitable for priv->eeprom. Propagating these changes throughout, iwl_find_otp_image() is found to be, now obviously visible, defective -- it uses the data returned by iwl_read_otp_word() directly as if it was CPU endianness. Fixing that, which is this hunk of the patch: - next_link_addr = link_value * sizeof(u16); + next_link_addr = le16_to_cpu(link_value) * sizeof(u16); is the only real change of this patch. Everything else is just fixing the sparse annotations. Also, the bug only shows up on big endian platforms with a 1000 series card. 5000 and previous series do not use OTP, and 6000 series has shadow RAM support which means we don't ever use the defective code on any cards but 1000.

2009-12-21drivers/net/wireless: Correct code taking the size of a pointerJulia Lawall
sizeof(iv16) and sizeof(iv32) are the sizes of pointers. Change them to the size of the copied data. Furthermore, iveiv_entry is a local structure that has just been initialized and is not visible outside this function. Thus, there would seem to be no point to copy data into it. The order of the arguments is thus changed to copy the data into the parameters, which are provided as pointers, suggesting in this case that they should be used to return values. A simplified version of the semantic patch that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2009-12-21ath9k: Last fix for TX software padding.Benoit Papillault
First, we copy/paste the padding stuff from ath9k_tx to ath_tx_cabq since it needs to same kind of padding, but for internally generated beacons. Next, software padding done on TX needs to be removed before calling ieee80211_tx_status. The code was already there in ath_tx_complete but it was wrong. Fix it by using ath9k_cmn_padpos.

2009-12-21iwlwifi: power up all devices for EEPROM readReinette Chatre
Recent commits "iwlwifi: remove power-wasting calls to apm_ops.init()" and "iwlagn: power up device before initializing EEPROM" had the goal of reducing device power consumption from the time the module is loaded until the interface is brought up and the device's power saving mechanisms kick in. The idea is that once the module is loaded there is no need for the device to consume power until the interface is brought up. With the current solution the device is only powered up during EEPROM read, and then so also only if the EEPROM type is OTP. We have found that on certain platforms even non-OTP devices require power to be up during EEPROM read. On these platforms the driver never loads and the system log contains the following: iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080403D8 We thus now power up all devices during EEPROM read. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-12-18can/at91: don't check platform_get_irq's return value against zeroUwe Kleine-König
platform_get_irq returns -ENXIO on failure, so !irq was probably always true. Better use (int)irq <= 0. Note that a return value of zero is still handled as error even though this could mean irq0. This is a followup to 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 that changed the return value of platform_get_irq from 0 to -ENXIO on error.

2009-12-18bnx2: reset_task is crashing the kernel. Fixing it.Breno Leitao
If bnx2 schedules a reset via the reset_task, e.g., due to a TX timeout, it's possible for the NIC to be disabled with packets pending for transmit. In this case, napi_disable will loop forever, eventually crashing the kernel. This patch moves the disable of the device to after the napi_disable call.

2009-12-18e100: Fix broken cbs accounting due to missing memset.Roger Oksanen
Alan Stern noticed that e100 caused slab corruption. commit 98468efddb101f8a29af974101c17ba513b07be1 changed the allocation of cbs to use dma pools that don't return zeroed memory, especially the cb->status field used to track which cb to clean, causing (the visible) double freeing of skbs and a wrong free cbs count. Now the cbs are explicitly zeroed at allocation time.

2009-12-15ixgbe: allow tx of pre-formatted vlan tagged packetsGurucharan Shetty
When the 82598 is fed 802.1q packets, it chokes with an error of the form: ixgbe: eth0: ixgbe_tx_csum: partial checksum but proto=81! As the logic there was not smart enough to look into the vlan header to pick out the encapsulated protocol. There are times when we'd like to send these packets out without having to configure a vlan on the interface. Here we check for the vlan tag and allow the packet to go out with the correct hardware checksum. This patch is a clone of a previously submitted patch by Arthur Jones <ajones@riverbed.com> for igb (Commit - fa4a7ef36ec834fee1719636b30d2f28f4cb0166).

Modified patch with Dave's comments to replace mdelay with proper msleep. Fix 82598 copper link issue, where the phy prematurely indicates link before it is ready to process packets. The new function looks for phy link and indicates that, when it is available. If phy is not ready within few seconds of MAC indicating link, the function will return failure which translates to link down indication.

2009-12-13can: Fix data length code handling in rx pathOliver Hartkopp
A valid CAN dataframe can have a data length code (DLC) of 0 .. 8 data bytes. When reading the CAN controllers register the 4-bit value may contain values from 0 .. 15 which may exceed the reserved space in the socket buffer! The ISO 11898-1 Chapter 8.4.2.3 (DLC field) says that register values > 8 should be reduced to 8 without any error reporting or frame drop. This patch introduces a new helper macro to cast a given 4-bit data length code (dlc) to __u8 and ensure the DLC value to be max. 8 bytes. The different handlings in the rx path of the CAN netdevice drivers are fixed.
