Conflicts: drivers/net/ethernet/freescale/fec_main.c drivers/net/ethernet/renesas/sh_eth.c net/ipv4/gre.c The GRE conflict is between a bug fix (kfree_skb --> kfree_skb_list) and the splitting of the gre.c code into seperate files. The FEC conflict was two sets of changes adding ethtool support code in an "!CONFIG_M5272" CPP protected block. Finally the sh_eth.c conflict was between one commit add bits set in the .eesr_err_check mask whilst another commit removed the .tx_error_check member and assignments. Signed-off-by: David S.

2009-09-07wan: dlci/sdla transmit return dehackingStephen Hemminger
This is a brute force removal of the wierd slave interface done for DLCI -> SDLA transmit. Before it was using non-standard return values and freeing skb in caller. This changes it to using normal return values, and freeing in the callee. Luckly only one driver pair was doing this. Not tested on real hardware, in fact I wonder if this driver pair is even being used by any users. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

2009-07-05net: convert remaining non-symbolic return values in ndo_start_xmit() functionsPatrick McHardy
This patch converts the remaining occurences of raw return values to their symbolic counterparts in ndo_start_xmit() functions that were missed by the previous automatic conversion. Additionally code that assumed the symbolic value of NETDEV_TX_OK to be zero is changed to explicitly use NETDEV_TX_OK. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-11-12netdevice: safe convert to netdev_priv() #part-3Wang Chen
We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

2008-11-03drivers/net: Kill now superfluous ->last_rx stores.David S. Miller
The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-03-26[NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.YOSHIFUJI Hideaki

2007-10-10[NET]: Make the device list and device lookups per namespace.Eric W. Biederman
This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[NET]: Make device event notification network namespace safeEric W. Biederman
Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-04-25[SK_BUFF]: Introduce skb_reset_mac_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
