usbnet: cleanup after bind() in probe()

2016-07-11T03:07:00Z

[ Upstream commit 1666984c8625b3db19a9abc298931d35ab7bc64b ] In case bind() works, but a later error forces bailing in probe() in error cases work and a timer may be scheduled. They must be killed. This fixes an error case related to the double free reported in http://www.spinics.net/lists/netdev/msg367669.html and needs to go on top of Linus' fix to cdc-ncm.

usbnet: Get EVENT_NO_RUNTIME_PM bit before it is cleared

2015-10-03T11:49:13Z

[ Upstream commit f50791ac1aca1ac1b0370d62397b43e9f831421a ] It is needed to check EVENT_NO_RUNTIME_PM bit of dev->flags in usbnet_stop(), but its value should be read before it is cleared when dev->flags is set to 0. The problem was spotted and the fix was provided by Oliver Neukum . Signed-off-by: Eugene Shatokhin Acked-by: Oliver Neukum Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

usbnet: avoid integer overflow in start_xmit

2015-05-09T20:46:18Z

transfer_buffer_length is of type u32. It's therefore wrong to assign it to a signed integer. This patch avoids the overflow. It's worth noting that entry->length here is a long; perhaps it would be beneficial at somepoint to change this to be unsigned as well, if nothing else relies on its signedness for error conditions or the like.

usbnet: rename work handler

2015-04-09T18:37:59Z

"kevent" is an extremely generic name that causes trouble if debugging for work queues is used. So change it to something clear. Signed-off-by: Oliver Neukum Signed-off-by: David S. Miller

usbnet: Fix tx_bytes statistic running backward in cdc_ncm

2015-03-29T19:06:45Z

cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path. Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a tx_bytes delta along with the tx_packets count.

usbnet: Fix tx_packets stat for FLAG_MULTI_FRAME drivers

2015-03-29T19:06:43Z

Currently the usbnet core does not update the tx_packets statistic for drivers with FLAG_MULTI_PACKET and there is no hook in the TX completion path where they could do this. cdc_ncm and dependent drivers are bumping tx_packets stat on the transmit path while asix and sr9800 aren't updating it at all. Add a packet count in struct skb_data so these drivers can fill it in, initialise it to 1 for other drivers, and add the packet count to the tx_packets statistic on completion.

usbnet: re-use native hex2bin()

usb: hub: rename khubd to hub_wq in documentation and comments

2014-09-24T05:33:19Z

USB hub has started to use a workqueue instead of kthread. Let's update the documentation and comments here and there. This patch mostly just replaces "khubd" with "hub_wq". There are only few exceptions where the whole sentence was updated. These more complicated changes can be found in the following files: Documentation/usb/hotplug.txt drivers/net/usb/usbnet.c drivers/usb/core/hcd.c drivers/usb/host/ohci-hcd.c drivers/usb/host/xhci.c Signed-off-by: Petr Mladek Acked-by: Alan Stern Signed-off-by: Greg Kroah-Hartman

cdc_subset: deal with a device that needs reset for timeout

This device needs to be reset to recover from a timeout. Unfortunately this can be handled only at the level of the subdrivers. Signed-off-by: Oliver Neukum Signed-off-by: David S. Miller
