drivers/net/usb: Correct code taking the size of a pointer

2010-01-06T22:26:25+00:00

commit 6057912d7baad31be9819518674ffad349a065b1 upstream. sizeof(dev->dev_addr) is the size of a pointer. A few lines above, the size of this field is obtained using netdev->addr_len for a call to memcpy, so do the same here. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // Signed-off-by: Julia Lawall Signed-off-by: David S.

hso: fix soft-lockup

2009-12-08T18:22:27+00:00

commit dcfcb256cc23c4436691b0fe677275306699d6a1 upstream. Fix soft-lockup in hso.c which is triggered on SMP machine when modem is removed while file descriptor(s) under /dev are still open: old version called kref_put() too early which resulted in destroying hso_serial and hso_device objects which were still used later on.

smsc95xx: fix transmission where ZLP is expected

2009-10-12T19:40:28+00:00

[ Upstream commit ec4756238239f1a331d9fb95bad8b281dad56855 ] Usbnet framework assumes USB hardware doesn't handle zero length packets, but SMSC LAN95xx requires these to be sent for correct operation. This patch fixes an easily reproducible tx lockup when sending a frame that results in exactly 512 bytes in a USB transmission (e.g. a UDP frame with 458 data bytes, due to IP headers and our USB headers). It adds an extra flag to usbnet for the hardware driver to indicate that it can handle and requires the zero length packets. This patch should not affect other usbnet users, please also consider for -stable. Signed-off-by: Steve Glendinning Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

kaweth: Fix memory leak in kaweth_control()

2009-10-05T16:31:58+00:00

commit 051b982bcc620695de629d29c333c95b66e9b95e upstream. kaweth_control() never frees the buffer that it allocates for the USB control message. Test case: while :; do ifconfig eth2 down ; ifconfig eth2 up ; done This is a tiny buffer so it is a slow leak. If you want to speed up the process, you can change the allocation size to e.g. 16384 bytes, and it will consume several megabytes within a few minutes.

USB host CDC Phonet network interface driver

2009-07-21T19:40:39+00:00

Many Nokia handsets support a Phonet interface to the cellular modem via a vendor-specific USB interface. CDC Phonet follows the Communications Device Class model, with one control interface, and and a pair of inactive and active data alternative interface. The later has two bulk endpoint, one per direction. This was tested against Nokia E61, Nokia N95, and the existing Phonet gadget function for the Linux composite USB gadget framework.

cdc-eem: bad crc checking

2009-07-17T01:06:25+00:00

When the driver received an EEM packet with CRC option enabled, driver must compute and check the CRC of the Ethernet data. Previous version computes CRC on Ethernet data plus the original CRC value. Skbuff is correctly trimed but the old length is used when CRC is computed. Signed-off-by: Vincent CUISSARD Signed-off-by: David S. Miller
