USB: kaweth.c: use GFP_ATOMIC under spin_lock

2012-08-09T15:27:52+00:00

[ Upstream commit e4c7f259c5be99dcfc3d98f913590663b0305bf8 ]

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.

cdc_ether: add Novatel USB551L device IDs for FLAG_WWAN

commit 4e6304b8420aba5311ba21fd68dab2924ae4d91a upstream.

Needs to be tagged with FLAG_WWAN, which since it has generic
descriptors, won't happen if we don't override the generic
driver info.

cdc_ether: Ignore bogus union descriptor for RNDIS devices

2012-05-21T16:40:02+00:00

commit 6eddcb4c82883451aec3be1240f17793370fa62f upstream.

Some RNDIS devices include a bogus CDC Union descriptor pointing
to non-existing interfaces.  The RNDIS code is already prepared
to handle devices without a CDC Union descriptor by hardwiring
the driver to use interfaces 0 and 1, which is correct for the
devices with the bogus descriptor as well. So we can reuse the
existing workaround.

usbnet: fix skb traversing races during unlink(v2)

2012-05-21T16:40:01+00:00

commit 5b6e9bcdeb65634b4ad604eb4536404bbfc62cfa upstream.

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock before unlink, but may
cause skb traversing races:
	- after URB is unlinked and the queue lock is released,
	the refered skb and skb->next may be moved to done queue,
	even be released
	- in skb_queue_walk_safe, the next skb is still obtained
	by next pointer of the last skb
	- so maybe trigger oops or other problems

This patch extends the usage of entry->state to describe 'start_unlink'
state, so always holding the queue(rx/tx) lock to change the state if
the referd skb is in rx or tx queue because we need to know if the
refered urb has been started unlinking in unlink_urbs.

The other part of this patch is based on Huajun's patch:
always traverse from head of the tx/rx queue to get skb which is
to be unlinked but not been started unlinking.

asix: Fix tx transfer padding for full-speed USB

2012-05-21T16:39:59+00:00

[ Upstream commit 2a5809499e35b53a6044fd34e72b242688b7a862 ]

The asix.c USB Ethernet driver avoids ending a tx transfer with a zero-
length packet by appending a four-byte padding to transfers whose length
is a multiple of maxpacket. However, the hard-coded 512 byte maxpacket
length is valid for high-speed USB only; full-speed USB uses 64 byte
packets.

smsc95xx: mark link down on startup and let PHY interrupt deal with carrier changes

commit 07d69d4238418746a7b85c5d05ec17c658a2a390 upstream.

Without this patch sysfs reports the cable as present

flag@flag-desktop:~$ cat /sys/class/net/eth0/carrier

flag@flag-desktop:~$ sudo mii-tool eth0
eth0: no link

net: usb: smsc75xx: fix mtu

2012-04-27T16:51:20+00:00

[ Upstream commit a99ff7d0123b19ecad3b589480b6542716ab6b52 ]

Make smsc75xx recalculate the hard_mtu after adjusting the
hard_header_len.

Without this, usbnet adjusts the MTU down to 1492 bytes, and the host is
unable to receive standard 1500-byte frames from the device.

Inspired by same fix on cdc_eem 78fb72f7936c01d5b426c03a691eca082b03f2b9.

Tested on ARM/Omap3 with EVB-LAN7500-LC.
