An extra list_del() during the module load failure and unload resulted in a crash with a list corruption. Now sctp can be unloaded again. Signed-off-by:

The Motorola MOTOMAGX phones (Z6, E8, Zn5 so far) are providing combined ACM/BLAN USB configuration. Since it has Vendor Specific class, the corresponding drivers (cdc-acm, zaurus) can't find it just by interface info. This patch adds usb id so the zaurus driver can properly handle this combined device. Signed-off-by:

Make usbnet_get_link() fall back to ethtool_op_get_link() instead of defaulting to 1. This makes usbnet_get_link return valid results without the need for a driver specific check_connect or mii ops as long as the driver calls netif_carrier_{on,off}() as appropriate. cdc_ether is an example of such a driver.

The current implementation of carrier detect in veth is broken. It reports the link is down until both sides of the veth pair are administatively up and then forever after it reports link up. So fix veth so that it only reports link up when both interfaces of the pair are administratively up. Signed-off-by:

The Ericsson F3507g wireless broadband module provides a CDC Ethernet compliant interface, but identifies it as a "Mobile Direct Line" CDC subclass, thereby preventing the CDC Ethernet class driver from picking it up. This patch adds the device id to cdc_ether.c as a workaround. Ericsson has provided a "class" driver for this device: http://kerneltrap.org/mailarchive/linux-net/2008/10/28/3832094 But closer inspection of that driver reveals that it adds little more than duplication of code from cdc_ether.c.

This is 2nd attempt to implement the initialization/reading of MAC address from EEPROM. The first used PCI's VPD and there were some problems, some devices are not able to read EEPROM content by VPD. The 2nd one uses direct access to EEPROM through bit-banging interface and my testing results seem to be much better. I tested 5 systems each with different Realtek NICs and I didn't find any problem. AFAIK Francois's NICs also works fine. Original description: This fixes the problem when MAC address is set by ifconfig or by ip link commands and this address is stored in the device after reboot. The power-off is needed to get right MAC address. This is problem when Xen daemon is running because it renames the device name from ethX to pethX and sets its MAC address to FE:FF:FF:FF:FF:FF. After reboot the device is still using FE:FF:FF:FF:FF:FF. Signed-off-by:

There's conflicting assumptions in shifting, the caller assumes that dupsack results in S'ed skbs (or a part of it) for sure but never gave a hint to tcp_sacktag_one when dsack is actually in use. Thus DSACK retrans_out -= pcount was not taken and the counter became out of sync. Remove obstacle from that information flow to get DSACKs accounted in tcp_sacktag_one as expected. Signed-off-by:

The netpoll entry checks are required to ensure that we don't receive normal packets when invoked via netpoll. Unfortunately it only ever worked for the netif_receive_skb/netif_rx entry points. The VLAN (and subsequently GRO) entry point didn't have the check and therefore can trigger all sorts of weird problems. This patch adds the netpoll check to all entry points. I'm still uneasy with receiving at all under netpoll (which apparently is only used by the out-of-tree kdump code). The reason is it is perfectly legal to receive all data including headers into highmem if netpoll is off, but if you try to do that with netpoll on and someone gets a printk in an IRQ handler you're going to get a nice BUG_ON.

As these ioctls are 32/64-bit compatible two simple COMPATIBLE_IOCTL entries in fs/compat_ioctl.c will do the job. Signed-off-by:

free_uid() and free_user_ns() are corecursive when CONFIG_USER_SCHED=n, but free_user_ns() is called from free_uid() by way of uid_hash_remove(), which requires uidhash_lock to be held. free_user_ns() then calls free_uid() to complete the destruction.

Feeding 32-bit length cast down to 'u16' to min() to calculate the FIFO count in musb_host_tx() risks sending a short packet prematurely for transfer sizes over 64 KB. Similarly, although data transfer size shouldn't exceed 65535 bytes for the control endpoint, making musb_h_ep0_continue() more robust WRT URBs with possibly oversized buffer will not hurt either...

For some strange reason the host side musb_giveback() decides that it's always got an IN transfer when the hardware endpoint is using a shared FIFO. This causes musb_save_toggle() to read the toggle state from the RXCSR register instead of TXCSR, and may also cause unneeded reloading of RX endpoint registers. Signed-off-by:

The musb_h_disable() routine can oops in some cases: - It's not safe to read hep->hcpriv outside musb->lock, since it gets changed on completion IRQ paths. - The list iterators aren't safe to use in that way; just remove the first element while !list_empty(), so deletions on other code paths can't make trouble. We need two "scrub the list" loops because only one branch should touch hardware and advance the schedule.
