This core is found on some Freescale SoCs and also some Coldfire SoCs. Support for Coldfire is missing though at the moment as they have an older revision of the core which does not have RX FIFO support. Signed-off-by:

There are two initializations of ndo_set_mac_address, one to a local function that is not used otherwise and one to a function that is defined elsewhere. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)<int(pr[0].line) or int(ps[0].column)<int(pr[0].column): cocci.print_main(fld,p0) // </smpl> akpm: - Use the standard eth_mac_addr() in uml_net_set_mac() - Remove unneeded and racy local set_ether_mac() - Remove duplicated (and incorrect) uml_netdev_ops.ndo_set_mac_address initializer.

Convert a few calls from kfree_skb to consume_skb Noticed while I was working on dropwatch that I was detecting lots of internal skb drops in several places. While some are legitimate, several were not, freeing skbs that were at the end of their life, rather than being discarded due to an error. This patch converts those calls sites from using kfree_skb to consume_skb, which quiets the in-kernel drop_monitor code from detecting them as drops. Tested successfully by myself Signed-off-by:

Patch to add -EAGAIN error to dropwatch netlink message handling code. -EAGAIN will be returned anytime userspace attempts to transition the state of the drop monitor service to a state that its already in. That allows user space to detect this condition, so it doesn't wait for a success ACK that will never arrive. Tested successfully by me Signed-off-by:

The new netpoll code in bridging contains use-after-free bugs that are non-trivial to fix. This patch fixes this by removing the code that uses skbs after they're freed. As a consequence, this means that we can no longer call bridge from the netpoll path, so this patch also removes the controller function in order to disable netpoll. Signed-off-by:

Even with jumbograms I cannot see any way in which we would need to records a larger than 65535 valued next-header offset. The maximum extension header length is (256 << 3) == 2048. There are only a handful of extension headers specified which we'd even accept (say 5 or 6), therefore the largest next-header offset we'd ever have to contend with is something less than say 16k. Therefore make it a u16 instead of a u32. Signed-off-by: -

smp_mb() inside bnx2_tx_avail() is used twice in the normal bnx2_start_xmit() path (see illustration below). The full memory barrier is only necessary during race conditions with tx completion. We can speed up the tx path by replacing smp_mb() in bnx2_tx_avail() with a compiler barrier. The compiler barrier is to force the compiler to fetch the tx_prod and tx_cons from memory. In the race condition between bnx2_start_xmit() and bnx2_tx_int(), we have the following situation: bnx2_start_xmit() bnx2_tx_int() if (!bnx2_tx_avail()) BUG(); ... if (!bnx2_tx_avail()) netif_tx_stop_queue(); update_tx_index(); smp_mb(); smp_mb(); if (bnx2_tx_avail()) if (netif_tx_queue_stopped() && netif_tx_wake_queue(); bnx2_tx_avail()) With smp_mb() removed from bnx2_tx_avail(), we need to add smp_mb() to bnx2_start_xmit() as shown above to properly order netif_tx_stop_queue() and bnx2_tx_avail() to check the ring index. If it is not strictly ordered, the tx queue can be stopped forever. This improves performance by about 5% with 2 ports running bi-directional 64-byte packets.

Yi Zou authored
When FCoE is disabled, there is a race condition that FCoE offload is turned off but the FCoE protocol driver is still queuing I/O thinking offload support still exists. This patch toggles off corresponding FCoE netdev feature flags and notify the FCoE stack first, allowing FCoE protocol stack driver to update its flags upon NETDEV_FEAT_CHANGE so no I/O will be using offload. Also, indicate FCoE offload flags in vlan_features in ixgbe_probe once and do not toggle them in ixgbe_fcoe_enable/disable so when FCoE is created on the VLAN interface, vlan_transfer_features() would properly update the VLAN netdev features flag and notify the FCoE protocol driver for NETDEV_FEAT_CHANGE.

This change removes UDP from the supported protocols for RSS hashing. The reason for removing this protocol is because IP fragmentation was causing a network flow to be broken into two streams, one for fragmented, and one for non-fragmented and this in turn was causing out-of-order issues.

This change makes it possible to limit the number of descriptors down to 48 per ring. The reason for this change is to address a variation on hardware errata 10 for 82546GB in which descriptors will be lost if more than 32 descriptors are fetched and the PCI-X MRBC is 512. Signed-off-by:

Hold rtnl_lock to get the right link state. While asynchronously resetting the device, hold rtnl_lock to get the right value from netif_running. If a reset is scheduled, and the device goes thru close and open, it may happen that reset and open may run in parallel. Holding rtnl_lock will avoid this. Signed-off-by:

It can happen that there are no packets in queue while calling tcp_xmit_retransmit_queue(). tcp_write_queue_head() then returns NULL and that gets deref'ed to get sacked into a local var.
