2010-09-27net: loopback driver cleanupEric Dumazet2-17/+9
loopback driver uses dev->ml_priv to store its percpu stats pointer. It uses ugly casts "(void __percpu __force *)" to shut up sparse complains. Define an union to better document we use ml_priv in loopback driver and define a lstats field with appropriate types. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2010-09-27net: fix rcu use in ip_route_output_slowEric Dumazet1-1/+1
__in_dev_get_rtnl(dev_out) is called while RTNL is not held, thus triggers a lockdep fault. At this point, we only perform a raw test of dev_out->ip_ptr being NULL, we dont need to make sure ip_ptr cant changed right after. We can use rcu_dereference_raw() for this.

2010-09-27rps: allocate rx queues in register_netdevice onlyEric Dumazet1-44/+32
Instead of having two places were we allocate dev->_rx, introduce netif_alloc_rx_queues() helper and call it only from register_netdevice(), not from alloc_netdev_mq() Goal is to let drivers change dev->num_rx_queues after allocating netdev and before registering it. This also removes a lot of ifdefs in net/core/dev.c Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-27net: update SOCK_MIN_RCVBUFEric Dumazet1-1/+5
SOCK_MIN_RCVBUF current value is 256 bytes It doesnt permit to receive the smallest possible frame, considering socket sk_rmem_alloc/sk_rcvbuf account skb truesizes. On 64bit arches, sizeof(struct sk_buff) is 240 bytes. Add the typical 64 bytes of headroom, and we go over the limit. With old kernels and 32bit arches, we were under the limit, if netdriver was doing copybreak. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-09-27net: skb_frag_t can be smaller on small archesEric Dumazet1-0/+5
On 32bit arches, if PAGE_SIZE is smaller than 65536, we can use 16bit offset and size fields. This patch saves 72 bytes per skb on i386, or 128 bytes after rounding. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-27net: propagate NETIF_F_HIGHDMA to vlansEric Dumazet1-3/+4
Automatically allows vlans to get NETIF_F_HIGHDMA if underlying device supports it. On 32bit arches (and more precisely if CONFIG_HIGHMEM is enabled), it can help to reduce cost of illegal_highdma() and __skb_linearize() calls. Tested on tg3 , bnx2, bonding, this worked very well. This is a generalization of a patch provided by Yi Zou & Jeff Kirsher. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-09-25ixgbevf: Refactor ring parameter re-sizeGreg Rose1-74/+79
The function to resize the Tx/Rx rings had the potential to dereference a NULL pointer and the code would attempt to resize the Tx ring even if the Rx ring allocation had failed. This would cause some confusion in the return code semantics. Fixed up to just unwind the allocations if any of them fail and return an error.

2010-09-25ip: take care of last fragment in ip_append_dataEric Dumazet1-3/+6
While investigating a bit, I found ip_fragment() slow path was taken because ip_append_data() provides following layout for a send(MTU + N*(MTU - 20)) syscall : - one skb with 1500 (mtu) bytes - N fragments of 1480 (mtu-20) bytes (before adding IP header) last fragment gets 17 bytes of trail data because of following bit: if (datalen == length + fraggap) alloclen += rt->dst.trailer_len; Then esp4 adds 16 bytes of data (while trailer_len is 17... hmm... another bug ?) In ip_fragment(), we notice last fragment is too big (1496 + 20) > mtu, so we take slow path, building another skb chain. In order to avoid taking slow path, we should correct ip_append_data() to make sure last fragment has real trail space, under mtu...

2010-09-24e1000: fix occasional panic on unloadJesse Brandeburg1-1/+19
Net drivers in general have an issue where timers fired by mod_timer or work threads with schedule_work are running outside of the rtnl_lock. With no other lock protection these routines are vulnerable to races with driver unload or reset paths. The longer term solution to this might be a redesign with safer locks being taken in the driver to guarantee no reentrance, but for now a safe and effective fix is to take the rtnl_lock in these routines.

2010-09-23e1000/e1000e/igb/ixgb/ixgbe: set NETIF_F_HIGHDMA for VLAN feature flagsYi Zou5-5/+15
If the netdev->features is set with NETIF_F_HIGHDMA, we should set the corresponding netdev->vlan_features as well to allow VLAN netdev created on top of the real netdev to be able to also benefit from HIGHDMA on 32bit system, reducing the performance hit that is caused by __skb_linearize(), particularly for large send. This is fixed in this patch for all Intel e1000, e1000e, igb, ixgbe, and ixgbe drivers since this should be beneficial to all devices supported by these drivers.

2010-09-21ath9k: clean up / fix aggregation session flushFelix Fietkau1-37/+26
The tid aggregation cleanup is a bit fragile, as it discards failed subframes in some places, and retransmits them in others. This could block the cleanup of an existing aggregation session, if a retransmission for a tid is issued, yet the tid is never scheduled again because of the cleanup state. Fix this by getting rid of as many subframes as possible, as early as possible, and immediately transmitting pending subframes as regular HT frames instead of waiting for the cleanup to complete. Drop all pending subframes while keeping track of the Block ACK window during aggregate tx completion to prevent sending out stale subframes, which could confuse the receiver side.
