usb/kaweth: use GFP_ATOMIC under spin_lock in usb_start_wait_urb()

2015-01-12T21:42:49Z

Commit e4c7f259c5be ("USB: kaweth.c: use GFP_ATOMIC under spin_lock") makes sure that kaweth_internal_control_msg() allocates memory with GFP_ATOMIC, but kaweth_internal_control_msg() also calls usb_start_wait_urb() that still allocates memory with GFP_NOIO. The patch fixes usb_start_wait_urb() as well. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by: Alexey Khoroshilov Acked-by: Oliver Neukum Signed-off-by: David S. Miller

net: get rid of SET_ETHTOOL_OPS

2014-05-13T21:43:20Z

net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.

drivers/net: delete non-required instances of include

2014-01-16T19:53:26Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. This covers everything under drivers/net except for wireless, which has been submitted separately. Signed-off-by: Paul Gortmaker Signed-off-by: David S. Miller

usb: Fix FSF address in file headers

2013-12-06T17:37:55Z

Several files refer to an old address for the Free Software Foundation in the file header comment. Resolve by replacing the address with the URL so that we do not have to keep updating the header comments anytime the address changes.

kaweth: print correct debug ptr

We nowdays copy the buffer and free fw->data, so make the debug printk use the right thing. Signed-off-by: Alan Cox Signed-off-by: David S. Miller

USB: remove dbg() usage in USB networking drivers

2012-09-20T21:53:14Z

The dbg() USB macro is so old, it predates me. The USB networking drivers are the last hold-out using this macro, and we want to get rid of it, so replace the usage of it with the proper netdev_dbg() or dev_dbg() (depending on the context) calls. Some places we end up using a local variable for the debug call, so also convert the other existing dev_* calls to use it as well, to save tiny amounts of code space.

USB: kaweth.c: use GFP_ATOMIC under spin_lock

2012-07-27T20:45:50Z

The problem is that we call this with a spin lock held. The call tree is: kaweth_start_xmit() holds kaweth->device_lock. -> kaweth_async_set_rx_mode() -> kaweth_control() -> kaweth_internal_control_msg() The kaweth_internal_control_msg() function is only called from kaweth_control() which used GFP_ATOMIC for its allocations.

USB: Disable hub-initiated LPM for comms devices.

2012-05-18T22:42:55Z

Hub-initiated LPM is not good for USB communications devices. Comms devices should be able to tell when their link can go into a lower power state, because they know when an incoming transmission is finished. Ideally, these devices would slam their links into a lower power state, using the device-initiated LPM, after finishing the last packet of their data transfer. If we enable the idle timeouts for the parent hubs to enable hub-initiated LPM, we will get a lot of useless LPM packets on the bus as the devices reject LPM transitions when they're in the middle of receiving data. Worse, some devices might blindly accept the hub-initiated LPM and power down their radios while they're in the middle of receiving a transmission. The Intel Windows folks are disabling hub-initiated LPM for all USB communications devices under a xHCI USB 3.0 host. In order to keep the Linux behavior as close as possible to Windows, we need to do the same in Linux. Set the disable_hub_initiated_lpm flag for for all USB communications drivers. I know there aren't currently any USB 3.0 devices that implement these class specifications, but we should be ready if they do.

USB: kaweth.c: remove err() usage

2012-04-25T19:37:48Z

err() was a very old USB-specific macro that I thought had gone away. This patch removes it from being used in the driver and uses dev_err() instead. Signed-off-by: Greg Kroah-Hartman
