The address stored in the next link address is a word address but when

valid so return an error.
The algorithm is simply valid blocks have a next address and that
address's contents is zero.
Using the wrong address for the next link address gets arbitrary data,
obviously. In cases seen, the first block is considered valid when it is not.
If the block has in fact been invalidated there may be old data or
there may be no data, bad data, or partial data, there is no way of

Additionally, the transmit side must check that the

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

Many projects cannot use splice(tcp -> pipe) because of this flaw.

Linus introduced SPLICE_F_NONBLOCK in commit
29e350944fdc2dfca102500790d8ad6d6ff4f69d
(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)

sky2: irqname based on pci address
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 ...

IPv4 TCP fails to send window scale option when window scale is zero
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.

3c59x: Rework suspend and resume
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.

If allocation of the second ports fails, make sure that hw->ports

This fix is copied from a similar fix in the sky2 driver (

ixgbe: Remove ATR computation for UDP traffic
ATR support for UDP on 82599 needs to be redesigned, since the
current model doesn't make much sense. The fallout from having
it in though is it causes all UDP traffic to still compute the
ATR hashes on transmit, which are useless. This removal will
return upwards of 10% of relative computational overhead in
forwarding tests.

ixgbe patch to provide NIC's tx/rx counters via ethtool
When LRO is enabled, the received packet and byte counters represent the
LRO'd packets, not the packets/bytes on the wire. The Intel 82599 NIC has
registers that keep count of the physical packets. Add these counters to
the ethtool stats. The byte counters are 36-bit, but the high 4 bits were
being ignored in the 2.6.31 ixgbe driver: Read those as well to allow
longer time between polling the stats to detect wraps.
