This patch will add support for the 82599 Dual port Backplane device (0x10f8). This device has the ability to link in serial (KR) and parallel (KX4/KX) modes, depending on what the switch capabilities are in the blade chassis.

tcp_splice_read() doesnt take into account socket's O_NONBLOCK flag Before this patch : splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE); causes a random endless block (if pipe is full) and splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK); will return 0 immediately if the TCP buffer is empty. User application has no way to instruct splice() that socket should be in blocking mode but pipe in nonblock more. Many projects cannot use splice(tcp -> pipe) because of this flaw. http://git.samba.org/?p=samba.git;a=history;f=source3/lib/recvfile.c;h=ea0159642137390a0f7e57a123684e6e63e47581;hb=HEAD http://lkml.indiana.edu/hypermail/linux/kernel/0807.2/0687.html Linus introduced SPLICE_F_NONBLOCK in commit 29e35094 (splice: add SPLICE_F_NONBLOCK flag ) It doesn't make the splice itself necessarily nonblocking (because the actual file descriptors that are spliced from/to may block unless they have the O_NONBLOCK flag set), but it makes the splice pipe operations nonblocking. Linus intention was clear : let SPLICE_F_NONBLOCK control the splice pipe mode only This patch instruct tcp_splice_read() to use the underlying file O_NONBLOCK flag, as other socket operations do. Users will then call : splice(socket,0,pipe,0,128*1024,SPLICE_F_MOVE | SPLICE_F_NONBLOCK ); to block on data coming from socket (if file is in blocking mode), and not block on pipe output (to avoid deadlock) First version of this patch was submitted by Octavian Purdila Reported-by: NVolker Lendecke <vl@samba.org> Reported-by: NJason Gunthorpe <jgunthorpe@obsidianresearch.com> Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NOctavian Purdila <opurdila@ixiacom.com> Acked-by: NLinus Torvalds <torvalds@linux-foundation.org> Acked-by: NJens Axboe <jens.axboe@oracle.com> Signed-off-by: NDavid S.

This patch against v2.6.31 adds support for route lookup using sk_mark in some more places. The benefits from this patch are the following. First, SO_MARK option now has effect on UDP sockets too. Second, ip_queue_xmit() and inet_sk_rebuild_header() could fail to do routing lookup correctly if TCP sockets with SO_MARK were used.

This is based on Michal Schmidt fix for skge. Most network drivers request their IRQ when the interface is activated. sky2 does it in ->probe() instead, because it can work with two-port cards where the two net_devices use the same IRQ. This works fine most of the time, except in some situations when the interface gets renamed. Consider this example: 1. modprobe sky2 The card is detected as eth0 and requests IRQ 17. Directory /proc/irq/17/eth0 is created. 2. There is an udev rule which says this interface should be called eth1, so udev renames eth0 -> eth1. 3. modprobe 8139too The Realtek card is detected as eth0. It will be using IRQ 17 too. 4. ip link set eth0 up Now 8139too requests IRQ 17. The result is: WARNING: at fs/proc/generic.c:590 proc_register ... proc_dir_entry '17/eth0' already registered The fix is for sky2 to name the irq based on the pci device, as is done by some other devices DRM, infiniband, ... ie. sky2@pci:0000:00:00 Signed-off-by: NStephen Hemminger <shemminger@vyatta.com> Reviewed-by: NMichal Schmidt <mschmidt@redhat.com> Signed-off-by: NDavid S.

And "ls /proc/irq/17" shows two subdirectories, both called eth0. Fix it by using a unique name for skge's IRQ, based on the PCI address. The naming from the example then looks like this: $ grep skge /proc/interrupts 17: 169 IO-APIC-fasteoi skge@pci:0000:00:0a.0, eth0 irqbalance daemon will have to be taught to recognize "skge@" as an Ethernet interrupt. This will be a one-liner addition in classify.c. I will send a patch to irqbalance if this change is accepted.

Acknowledge TCP window scale support by inserting the proper option in SYN/ACK and SYN headers even if our window scale is zero. This fixes the following observed behavior: 1. Client sends a SYN with TCP window scaling option and non zero window scale value to a Linux box. 2. Linux box notes large receive window from client. 3. Linux decides on a zero value of window scale for its part. 4. Due to compare against requested window scale size option, Linux does not to send windows scale TCP option header on SYN/ACK at all. With the following result: Client box thinks TCP window scaling is not supported, since SYN/ACK had no TCP window scale option, while Linux thinks that TCP window scaling is supported (and scale might be non zero), since SYN had TCP window scale option and we have a mismatched idea between the client and server regarding window sizes. Probably it also fixes up the following bug (not observed in practice): 1. Linux box opens TCP connection to some server. 2. Linux decides on zero value of window scale. 3. Due to compare against computed window scale size option, Linux does not to set windows scale TCP option header on SYN. With the expected result that the server OS does not use window scale option due to not receiving such an option in the SYN headers, leading to suboptimal performance.

Primary module parameter passed to bonding is pernament. That means if you release the primary slave and enslave it again, it becomes the primary slave again. But if you set primary slave via sysfs, the primary slave is only set once and it's not remembered in bond->params structure. Therefore the setting is lost after releasing the primary slave.

As noticed by Alan Stern, there is still one issue with the driver: we disable PCI IRQ on suspend, but other devices on the same IRQ line might still need the IRQ enabled to suspend properly. Nowadays, PCI core handles all power management work by itself, with one condition though: if we use dev_pm_ops. So, rework the driver to only quiesce 3c59x internal logic on suspend, while PCI core will manage PCI device power state with IRQs disabled. Suggested-by: NRafael J.
