usbnet: remove generic hard_header_len check

2014-02-26T09:22:52Z

[ Upstream commit eb85569fe2d06c2fbf4de7b66c263ca095b397aa ] This patch removes a generic hard_header_len check from the usbnet module that is causing dropped packages under certain circumstances for devices that send rx packets that cross urb boundaries. One example is the AX88772B which occasionally send rx packets that cross urb boundaries where the remaining partial packet is sent with no hardware header. When the buffer with a partial packet is of less number of octets than the value of hard_header_len the buffer is discarded by the usbnet module. With AX88772B this can be reproduced by using ping with a packet size between 1965-1976. The bug has been reported here: https://bugzilla.kernel.org/show_bug.cgi?id=29082 This patch introduces the following changes: - Removes the generic hard_header_len check in the rx_complete function in the usbnet module. - Introduces a ETH_HLEN check for skbs that are not cloned from within a rx_fixup callback. - For safety a hard_header_len check is added to each rx_fixup callback function that could be affected by this change. These extra checks could possibly be removed by someone who has the hardware to test. - Removes a call to dev_kfree_skb_any() and instead utilizes the dev->done list to queue skbs for cleanup. The changes place full responsibility on the rx_fixup callback functions that clone skbs to only pass valid skbs to the usbnet_skb_return function.

net: asix: add missing flag to struct driver_info

2014-02-26T09:22:52Z

[ Upstream commit d43ff4cd798911736fb39025ec8004284b1b0bc2 ] The struct driver_info ax88178_info is assigned the function asix_rx_fixup_common as it's rx_fixup callback. This means that FLAG_MULTI_PACKET must be set as this function is cloning the data and calling usbnet_skb_return. Not setting this flag leads to usbnet_skb_return beeing called a second time from within the rx_process function in the usbnet module.

[ Upstream commit fdc3452cd2c7b2bfe0f378f92123f4f9a98fa2bd ] Commit 60e453a940ac ("USBNET: fix handling padding packet") added an extra SG entry in case padding is necessary, but failed to update the initialisation of the list. This can cause list traversal to fall off the end of the list, resulting in an oops.

dm9601: work around tx fifo sync issue on dm962x

2014-01-09T20:25:12Z

commit 4263c86dca5198da6bd3ad826d0b2304fbe25776 upstream. Certain dm962x revisions contain an bug, where if a USB bulk transfer retry (E.G. if bulk crc mismatch) happens right after a transfer with odd or maxpacket length, the internal tx hardware fifo gets out of sync causing the interface to stop working. Work around it by adding up to 3 bytes of padding to ensure this situation cannot trigger. This workaround also means we never pass multiple-of-maxpacket size skb's to usbnet, so the length adjustment to handle usbnet's padding of those can be removed.

usbnet: fix status interrupt urb handling

2013-12-08T15:29:11Z

[ Upstream commit 52f48d0d9aaa621ffa5e08d79da99a3f8c93b848 ] Since commit 7b0c5f21f348a66de495868b8df0284e8dfd6bbf "sierra_net: keep status interrupt URB active", sierra_net triggers status interrupt polling before the net_device is opened (in order to properly receive the sync message response). To be able to receive further interrupts, the interrupt urb needs to be re-submitted, so this patch removes the bogus check for netif_running().
