2007-07-14[VLAN]: Use multicast list synchronization helpersPatrick McHardy
Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-14[VLAN]: Fix promiscous/allmulti synchronization racesPatrick McHardy
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. Use the change_rx_mode hook, which is always invoked under the rtnl. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-11[VLAN]: Fix MAC address handlingPatrick McHardy
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.

2007-07-10[VLAN]: Keep track of number of QoS mappingsPatrick McHardy
Keep track of the number of configured ingress/egress QoS mappings to avoid iteration while calculating the netlink attribute size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-07-10[VLAN]: Convert name-based configuration functions to struct netdevice *Patrick McHardy
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.

2007-04-25[NET]: cleanup extra semicolonsStephen Hemminger
Spring cleaning time... There seems to be a lot of places in the network code that have extra bogus semicolons after conditionals. Most commonly is a bogus semicolon after: switch() { } Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-13[VLAN]: Allow VLAN interface on top of bridge interfaceJerome Borsboom
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>

2006-03-20[NET]: Replace skb_pull/skb_postpull_rcsum with skb_pull_rcsumHerbert Xu
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.

2005-08-29[NET]: Kill skb->real_devDavid S. Miller
Bonding just wants the device before the skb_bond() decapsulation occurs, so simply pass that original device into packet_type->func() as an argument. It remains to be seen whether we can use this same exact thing to get rid of skb->input_dev as well. Signed-off-by: David S. Miller <davem@davemloft.net>
2005-04-16Linux-2.6.12-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!
