2011-02-17drivers/net: Call netif_carrier_off at the end of the probeIvan Vecera
Without calling of netif_carrier_off at the end of the probe the operstate is unknown when the device is initially opened. By default the carrier is on so when the device is opened and netif_carrier_on is called the link watch event is not fired and operstate remains zero (unknown). This patch fixes this behavior in forcedeth and r8169. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Acked-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: David S.

2011-02-17IB/qib: Prevent double completions after a timeout or RNR errorMike Marciniszyn
There is a double completion associated with error handling for RC QPs. The sequence is: - The do_rc_ack() routine fields an RNR nack and there are 0 rnr_retries configured on the QP. - qib_error_qp() stops the pending timer - qib_rc_send_complete() is called from sdma_complete() - qib_rc_send_complete() starts the timer because the msb of the psn just completed says an ack is needed. - a bunch of flushes occur as ipoib posts WQEs to an error'ed QP - rc_timeout() calls qib_restart_rc() - qib_restart_rc() calls qib_send_complete() with a IB_WC_RETRY_EXC_ERR on a wqe that has already been completed in the past The fix avoids starting the timer since another packet will never arrive.

2011-02-17sfc: Implement hardware acceleration of RFSBen Hutchings
Use the existing filter management functions to insert TCP/IPv4 and UDP/IPv4 4-tuple filters for Receive Flow Steering. For each channel, track how many RFS filters are being added during processing of received packets and scan the corresponding number of table entries for filters that may be reclaimed. Do this in batches to reduce lock overhead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2011-02-17netfilter: tproxy: do not assign timewait sockets to skb->skFlorian Westphal
Assigning a socket in timewait state to skb->sk can trigger kernel oops, e.g. in nfnetlink_log, which does: if (skb->sk) { read_lock_bh(&skb->sk->sk_callback_lock); if (skb->sk->sk_socket && skb->sk->sk_socket->file) ... in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket is invalid. Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT, or xt_TPROXY must not assign a timewait socket to skb->sk. This does the latter. If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment, thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule. The 'SYN to TW socket' case is left unchanged -- we try to redirect to the listener socket.

It turns out hw->mac.ops.setup_sfp is only set for 82599, so one should check to be sure that pointer is set before continuing in ixgbe_sfp_config_module_task.

2011-02-16block: revert block_dev read-only checkChuck Ebbert
This reverts commit 75f1dc0d076d ("block: check bdev_read_only() from blkdev_get()"). That commit added stricter checking to make sure devices that were being used read-only were actually opened in that mode. It turns out that the change breaks a bunch of kernel code that opens block devices. Affected systems include dm, md, and the loop device. Because strict checking for read-only opens of block devices was not done before this, the code that opens the devices was opening them read-write even if they were being used read-only. Auditing all that code will take time, and new userspace packages for dm, mdadm, etc. will also be required.

2011-02-17drm/nv40: fix tiling-related setup for a number of chipsetsBen Skeggs
Due to the default case handling the older chipsets, a bunch of the newer ones ended up having the wrong tiling regs used. This commit switches the default case to handle the newest chipsets. This also makes nv4e touch the "extra" tiling regs. "nv" doesn't touch them for C51 but traces of the NVIDIA binary driver show it being done there. I couldn't find NV41/NV45 traces to confirm the behaviour there, but an educated guess was taken at each of them. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
