Network device TX is never run in IRQ context, and skb is freed outside of the IRQ-disabling spin lock. So checking for IRQ was a waste of time here. Signed-off-by:

Add 'autoconf' and 'disable_ipv6' parameters to the IPv6 module. The first controls if IPv6 addresses are autoconfigured from prefixes received in Router Advertisements. The IPv6 loopback (::1) and link-local addresses are still configured. The second controls if IPv6 addresses are desired at all. No IPv6 addresses will be added to any interfaces. Signed-off-by:

We should not be stopping the subqueues in cpmac_end_xmit but rather test the status of them. Replace the calls to netif_subqueue_stop by __netif_subqueue_stopped. This fixes an unrecoverable exception from happening when running the driver. Signed-off-by:

This patch adds a generic driver for SJA1000 chips on the OpenFirmware platform bus found on embedded PowerPC systems. You need a SJA1000 node definition in your flattened device tree source (DTS) file similar to: can@3,100 { compatible = "nxp,sja1000"; reg = <3 0x100 0x80>; interrupts = <2 0>; interrupt-parent = <&mpic>; nxp,external-clock-frequency = <16000000>; }; See also Documentation/powerpc/dts-bindings/can/sja1000.txt.

As discussed on the netdev mailing list, the member "base_addr" of "struct net_device" should not be (mis)used to store the virtual address to the SJA1000 register area. According to David Miller, it's only use is to allow ISA and similar primitive bus devices to have their I/O ports changed via ifconfig. The virtual address is now stored in the private data structure of the SJA1000 device and the callback functions use "struct sja1000_priv" instead of the unneeded "struct net_device". Signed-off-by:

Warning messages coming from rtl8150 driver can flood the console and make a DTV/set-top-box unable to decode video/audio frames. 'Pegasus' driver handles this situation similarly, preventing this from happening there. It happens with a low cost BCM MIPS embedded platform, whenever timeout errors were coming from usbnet device, making platform unusable for viewer watching. Signed-off-by:

This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial. Signed-off-by:

Writes to the DMA descriptors may sit in the internal Blackfin data buffers and not actually be available when the DMA engine goes to fetch them. This does not typically happen, but when dealing with short/fast packets such as UDP and polling KGDB, this occurs much more frequently. Same goes for heavy loads as seen by netperf tests or large scp transfers. So force the buffers to drain with SSYNC otherwise we get random malformed packets. Signed-off-by:

Somewhat luckily, I was looking into these parts with very fine comb because I've made somewhat similar changes on the same area (conflicts that arose weren't that lucky though). The loop was very much overengineered recently in commit 91521944 (tcp: Use SKB queue and list helpers instead of doing it by-hand), while it basically just wants to know if there are skbs after 'skb'. Also it got broken because skb1 = skb->next got translated into skb1 = skb1->next (though abstracted) improperly. Note that 'skb1' is pointing to previous sk_buff than skb or NULL if at head. Two things went wrong: - We'll kfree 'skb' on the first iteration instead of the skbuff following 'skb' (it would require required SACK reneging to recover I think). - The list head case where 'skb1' is NULL is checked too early and the loop won't execute whereas it previously did. Conclusion, mostly revert the recent changes which makes the cset very messy looking but using proper accessor in the previous-like version. The effective changes against the original can be viewed with: git-diff 91521944^ \ net/ipv4/tcp_input.c | sed -n -e '57,70 p' Signed-off-by:

[PATCH net-next] bonding: allow bond in mode balance-alb to work properly in bridge -try4.3 (updated) changes v4.2 -> v4.3 - memcpy the address always, not just in case it differs from master->dev_addr - compare_ether_addr_64bits() is not used so there is no direct need to make new header file (I think it would be good to have bond stuff in separate file anyway). changes v4.1 -> v4.2 - use skb->pkt_type == PACKET_HOST compare rather then comparing skb dest addr against skb->dev->dev_addr The problem is described in following bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=487763 Basically here's what's going on. In every mode, bonding interface uses the same mac address for all enslaved devices (except fail_over_mac). Only balance-alb will simultaneously use multiple MAC addresses across different slaves. When you put this kind of bond device into a bridge it will only add one of mac adresses into a hash list of mac addresses, say X. This mac address is marked as local. But this bonding interface also has mac address Y. Now then packet arrives with destination address Y, this address is not marked as local and the packed looks like it needs to be forwarded. This packet is then lost which is wrong. Notice that interfaces can be added and removed from bond while it is in bridge. *** When the multiple addresses for bridge port approach failed to solve this issue due to STP I started to think other way to solve this. I returned to previous solution but tweaked one. This patch solves the situation in the bonding without touching bridge code. For every incoming frame to bonding the destination address is compared to current address of the slave device from which tha packet came. If these two match destination address is replaced by mac address of the master. This address is known by bridge so it is delivered properly. Note that the comparsion is not made directly, it's used skb->pkt_type == PACKET_HOST instead. This is "set" previously in eth_type_trans(). I experimentally tried that this works as good as searching through the slave list (v4 of this patch). Jirka Signed-off-by:
