[NET]: Fix two issues wrt. SO_BINDTODEVICE.

2007-09-14T23:41:03+00:00

1) Comments suggest that setting optlen to zero will unbind
   the socket from whatever device it might be attached to.  This
   hasn't been the case since at least 2.2.x because the first thing
   this function does is return -EINVAL if 'optlen' is less than
   sizeof(int).

   This check also means that passing in a two byte string doesn't
   work so well.  It's almost as if this code was testing with "eth?"
   patterned strings and nothing else :-)

   Fix this by breaking the logic of this facility out into a
   seperate function which validates optlen more appropriately.

   The optlen==0 and small string cases now work properly.

2) We should reset the cached route of the socket after we have made
   the device binding changes, not before.

[NET]: Do not dereference iov if length is zero

2007-09-11T08:29:07+00:00

When msg_iovlen is zero we shouldn't try to dereference
msg_iov.  Right now the only thing that tries to do so
is skb_copy_and_csum_datagram_iovec.  Since the total
length should also be zero if msg_iovlen is zero, it's
sufficient to check the total length there and simply
return if it's zero.

[PKTGEN]: Remove write-only variable.

2007-08-31T05:46:36+00:00

The pktgen_thread.pid is set to current->pid and is never used
after this. So remove this at all.

Found during isolating the explicit pid/tgid usage.

[PKTGEN]: Fix multiqueue oops.

2007-08-28T22:43:14+00:00

Initially pkt_dev can be NULL this causes netif_subqueue_stopped to 
oops. The patch below should cure it. But maybe the pktgen TX logic 
should be reworked to better support the new multiqueue support.

[NET]: Fix crash in dev_mc_sync()/dev_mc_unsync()

2007-08-27T01:35:43+00:00

This patch fixes a crash that may occur when the routine dev_mc_sync()
deletes an address from the list it is currently going through. It
saves the pointer to the next element before deleting the current one.
The problem may also exist in dev_mc_unsync().

[NET]: Share correct feature code between bridging and bonding

2007-08-14T05:52:14+00:00

http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the
bonding driver may produce bogus combinations of the checksum
flags and SG/TSO.

For example, if you bond devices with NETIF_F_HW_CSUM and
NETIF_F_IP_CSUM you'll end up with a bonding device that
has neither flag set.  If both have TSO then this produces
an illegal combination.

The bridge device on the other hand has the correct code to
deal with this.

In fact, the same code can be used for both.  So this patch
moves that logic into net/core/dev.c and uses it for both
bonding and bridging.

In the process I've made small adjustments such as only
setting GSO_ROBUST if at least one constituent device
supports it.

net_msg_warn is not defined because it is in net/sock.h which isn't
