* [NET]: ethtool ops are the only wayMatthew Wilcox2007-07-311-3/+0
| | | | | | | | | | | | | | | During the transition to the ethtool_ops way of doing things, we supported calling the device's ->do_ioctl method to allow unconverted drivers to continue working. Those days are long behind us, all in-tree drivers use the ethtool_ops way, and so we no longer need to support this. The bonding driver is the biggest beneficiary of this; it no longer needs to call ioctl() as a fallback if ethtool_ops aren't supported. Also put a proper copyright statement on ethtool.c.

| | | | | | | | | | The set_multicast_list function may be called without holding the rtnl mutex, resulting in races when changing the underlying device's promiscous and allmulti state.

* [RTNETLINK]: rtnl_link: allow specifying initial device addressPatrick McHardy2007-07-122-2/+13

* [RTNETLINK]: rtnl_link API simplificationPatrick McHardy2007-07-121-21/+0
| | | | | | | | | | | | | | All drivers need to unregister their devices in the module unload function. While doing so they must hold the rtnl and atomically unregister the rtnl_link ops as well. This makes the rtnl_link_unregister function that takes the rtnl itself completely useless. Provide default newlink/dellink functions, make __rtnl_link_unregister and rtnl_link_unregister unregister all devices with matching rtnl_link_ops and change the existing users to take advantage of that.

* [VLAN]: Fix MAC address handlingPatrick McHardy2007-07-123-45/+56
| | | | | | | | | | | | | | | | | | The VLAN MAC address handling is broken in multiple ways. When the address differs when setting it, the real device is put in promiscous mode twice, but never taken out again. Additionally it doesn't resync when the real device's address is changed and needlessly puts it in promiscous mode when the vlan device is still down. Fix by moving address handling to vlan_dev_open/vlan_dev_stop and properly deal with address changes in the device notifier. Also switch to dev_unicast_add (which needs the exact same handling). Since the set_mac_address handler is identical to the generic ethernet one with these changes, kill it and use ether_setup(). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* [VLAN]: Convert name-based configuration functions to struct netdevice *Patrick McHardy2007-07-113-199/+109
| | | | | | | | | | | | | | | | | Move the device lookup and checks to the ioctl handler under the RTNL and change all name-based interfaces to take a struct net_device * instead. This allows to use them from a netlink interface, which identifies devices based on ifindex not name. It also avoids races between the ioctl interface and the (upcoming) netlink interface since now all changes happen under the RTNL. As a nice side effect this greatly simplifies error handling in the helper functions and fixes a number of incorrect error codes like -EINVAL for device not found.

* VLAN: kill_vid is only useful for VLAN filtering devicesStephen Hemminger2007-06-031-7/+3
| | | | | | | | | | | | | | The interface for network device VLAN extension was confusing. The kill_vid function is only really useful for devices that do hardware filtering. Devices that only do VLAN receiption without filtering were being forced to provide the hook, and there were bugs in those devices. Many drivers had kill_vid routine that called vlan_group_set_device, with NULL, but that is done already.

* [VLAN]: Allow VLAN interface on top of bridge interfaceJerome Borsboom2007-04-141-0/+3
| | | | | | | | | | | | | | When a VLAN interface is created on top of a bridge interface and netfilter is enabled to see the bridged packets, the packets can be corrupted when passing through the netfilter code. This is caused by the VLAN driver not setting the 'protocol' and 'nh' members of the sk_buff structure. In general, this is no problem as the VLAN interface is mostly connected to a physical ethernet interface which does not use the 'protocol' and 'nh' members. For a bridge interface, however, these members do matter. Signed-off-by: Jerome Borsboom <j.borsboom@erasmusmc.nl> Signed-off-by: David S. Miller <davem@davemloft.net>
* [VLAN]: Avoid a 4-order allocation.Dan Aloni2007-03-031-10/+32
| | | | | | | | | | | | | | This patch splits the vlan_group struct into a multi-allocated struct. On x86_64, the size of the original struct is a little more than 32KB, causing a 4-order allocation, which is prune to problems caused by buddy-system external fragmentation conditions. I couldn't just use vmalloc() because vfree() cannot be called in the softirq context of the RCU callback.

* [NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsumHerbert Xu2006-03-211-4/+2
| | | | | | | | | | | | | | | | | | | | We're now starting to have quite a number of places that do skb_pull followed immediately by an skb_postpull_rcsum. We can merge these two operations into one function with skb_pull_rcsum. This makes sense since most pull operations on receive skb's need to update the checksum. I've decided to make this out-of-line since it is fairly big and the fast path where hardware checksums are enabled need to call csum_partial anyway. Since this is a brand new function we get to add an extra check on the len argument. As it is most callers of skb_pull ignore its return value which essentially means that there is no check on the len argument.

* [VLAN]: Fix early vlan adding leads to not functional deviceTommy Christensen2005-07-121-0/+8
| | | | | | | | | | | | | | OK, I can see what's happening here. eth0 doesn't detect link-up until after a few seconds, so when the vlan interface is opened immediately after eth0 has been opened, it inherits the link-down state. Subsequently the vlan interface is never properly activated and are thus unable to transmit any packets. dev->state bits are not supposed to be manipulated directly. Something similar is probably needed for the netif_device_present() bit, although I don't know how this is meant to work for a virtual device. Signed-off-by: David S. Miller <davem@davemloft.net>

Most visible are the INET changes where several "depends on INET" are replaced with a single ifdef INET / endif pair. Several new files were created to accomplish this change - they are small but serve the purpose that config options are now distributed out where they belongs.
