struct sk_buff uses one union to define dst and rtable fields. We want to replace direct access to these pointers by accessors. First patch adds a new "unsigned long _skb_dst;" opaque field in this union. Signed-off-by:

With bi-directional stress traffic, the receiver could hang causing the hardware to stop and a "Detected Tx Unit Hang" message dumped to the system logfile. Temporarily workaround this issue by disabling Tx flow control by default. The issue is currently being investigated and a follow-on patch will be provided to revert this when it is resolved.

This patch provides support for the next generation Intel desktop and mobile gigabit ethernet LOM adapters. These adapters are the follow-on parts to the LOMs tied to the prior ICH chipsets and are comprised of a MAC in the PCH chipset and an external PHY (82577 for mobile and 82578 for desktop versions). New features consist of PHY wakeup to save power by completely turning off the MAC while in Sx state, and 4K jumbo frames. Signed-off-by:

The flow control thresholds, i.e. high and low watermarks of the Rx FIFO for when the hardware should transmit PAUSE frames (XON and XOFF, respectively), need to be tuned for more efficient use of the FIFO. The logic to set the thresholds for parts that support early-receive (ERT) was also wrong in that it should check whether jumbo frames are in use. Signed-off-by:

By default the driver opens 8 TX queues (defined by MLX4_EN_NUM_TX_RINGS). If the driver is configured to support Per Priority Flow Control, we open 8 additional TX rings. dev->real_num_tx_queues is always set to be MLX4_EN_NUM_TX_RINGS. The mlx4_en_select_queue() function uses standard hashing (skb_tx_hash) in case that PPFC is not supported or the skb contain a vlan tag, otherwise the queue is selected according to vlan priority.

net_cls: fix unconfigured struct tcf_proto keeps chaining and avoid kernel panic when we use cls_cgroup This patch fixes a bug which unconfigured struct tcf_proto keeps chaining in tc_ctl_tfilter(), and avoids kernel panic in cls_cgroup_classify() when we use cls_cgroup. When we execute 'tc filter add', tcf_proto is allocated, initialized by classifier's init(), and chained. After it's chained, tc_ctl_tfilter() calls classifier's change(). When classifier's change() fails, tc_ctl_tfilter() does not free and keeps tcf_proto. In addition, cls_cgroup is initialized in change() not in init(). It accesses unconfigured struct tcf_proto which is chained before change(), then hits Oops. Signed-off-by:

Patch to fix bad length checking in e1000. E1000 by default does two things: 1) Spans rx descriptors for packets that don't fit into 1 skb on recieve 2) Strips the crc from a frame by subtracting 4 bytes from the length prior to doing an skb_put Since the e1000 driver isn't written to support receiving packets that span multiple rx buffers, it checks the End of Packet bit of every frame, and discards it if its not set. This places us in a situation where, if we have a spanning packet, the first part is discarded, but the second part is not (since it is the end of packet, and it passes the EOP bit test). If the second part of the frame is small (4 bytes or less), we subtract 4 from it to remove its crc, underflow the length, and wind up in skb_over_panic, when we try to skb_put a huge number of bytes into the skb. This amounts to a remote DOS attack through careful selection of frame size in relation to interface MTU. The fix for this is already in the e1000e driver, as well as the e1000 sourceforge driver, but no one ever pushed it to e1000. This is lifted straight from e1000e, and prevents small frames from causing the underflow described above Signed-off-by:

After some discussion offline with Christoph Lameter and David Stevens regarding multicast behaviour in Linux, I'm submitting a slightly modified patch from the one Christoph submitted earlier. This patch provides a new socket option IP_MULTICAST_ALL. In this case, default behaviour is _unchanged_ from the current Linux standard. The socket option is set by default to provide original behaviour. Sockets wishing to receive data only from multicast groups they join explicitly will need to clear this socket option.

Add a phy_power_down parameter to forcedeth: set to 1 to power down the phy and disable the link when an interface goes down; set to 0 to always leave the phy powered up. The phy power state persists across reboots; Windows, some BIOSes, and older versions of Linux don't bother to power up the phy again, forcing users to remove all power to get the interface working (see http://bugzilla.kernel.org/show_bug.cgi?id=13072). Leaving the phy powered on is the safest default behavior. Users accustomed to seeing the link state reflect the interface state and/or wanting to minimize power consumption can set phy_power_down=1 if compatibility with other OSes is not an issue.

This patch adds a generic driver for SJA1000 chips on the OpenFirmware platform bus found on embedded PowerPC systems. You need a SJA1000 node definition in your flattened device tree source (DTS) file similar to: can@3,100 { compatible = "nxp,sja1000"; reg = <3 0x100 0x80>; interrupts = <2 0>; interrupt-parent = <&mpic>; nxp,external-clock-frequency = <16000000>; }; See also Documentation/powerpc/dts-bindings/can/sja1000.txt.

As discussed on the netdev mailing list, the member "base_addr" of "struct net_device" should not be (mis)used to store the virtual address to the SJA1000 register area. According to David Miller, it's only use is to allow ISA and similar primitive bus devices to have their I/O ports changed via ifconfig. The virtual address is now stored in the private data structure of the SJA1000 device and the callback functions use "struct sja1000_priv" instead of the unneeded "struct net_device". Signed-off-by:
