2010-08-23Staging: batman-adv: Don't write in not allocated packet_buffSven Eckelmann
Each net_device in a system will automatically managed as a possible batman_if and holds different informations like a buffer with a prepared originator messages. To reduce the memory usage, the packet_buff will only be allocated when the interface is really added/enabled for batman-adv. The function to update the hw address information inside the packet_buff just assumes that the packet_buff is always initialised and thus the kernel will just oops when we try to change the hw address of a not already fully enabled interface. We must always check if the packet_buff is allocated before we try to change information inside of it.

2010-08-23Staging: batman-adv: Don't use net_dev after dev_putSven Eckelmann
dev_put allows a device to be freed when all its references are dropped. After that we are not allowed to access that information anymore. Access to the data structure of a net_device must be surrounded a dev_hold and ended using dev_put. batman-adv adds a device to its own management structure in hardif_add_interface and will release it in hardif_remove_interface. Thus it must hold a reference all the time between those functions to prevent any access to the already released net_device structure.

2010-08-23Staging: batman-adv: Create batman_if only on register eventSven Eckelmann
We try to get all events for all net_devices to be able to add special sysfs folders for the batman-adv configuration. This also includes such events like NETDEV_POST_INIT which has no valid kobject according to v2.6.32-rc3-13-g7ffbe3f. This would create an oops in that situation. It is enough to create the batman_if only on NETDEV_REGISTER events because we will also receive those events for devices which already existed when we registered the notifier call.

2010-08-23Staging: batman-adv: fix own mac address detectionMarek Lindner
Earlier batman-adv versions would only create a batman_if struct after a corresponding interface had been activated by a user. Now each existing system interface has a batman_if struct and has to be checked by verifying the IF_ACTIVE flag.

2010-08-23Staging: batman-adv: always reply batman icmp packets with primary macMarek Lindner
When receiving an batman icmp echo request or in case of a time-to-live exceeded batman would reply with the mac address of the outgoing interface which might be a secondary interface. Because secondary interfaces are not globally known this might lead to confusion. Now, replies are sent with the mac address of the primary interface.

2010-08-23Staging: batman-adv: fix batman icmp originating from secondary interfaceMarek Lindner
If a batman icmp packet had to be routed over a secondary interface at the first hop, the mac address of that secondary interface would be written in the 'orig' field of the icmp packet. A node which is more than one hop away is not aware of the mac address because secondary interfaces are not flooded through the whole mesh and therefore can't send a reply. This patch always sends the mac address of the primary interface in the 'orig' field of the icmp packet.

2010-08-23block: add function call to switch the IO scheduler from a driverJens Axboe
Currently drivers must do an elevator_exit() + elevator_init() to switch IO schedulers. There are a few problems with this: - Since commit 1abec4fdbb142e3ccb6ce99832fae42129134a96, elevator_init() requires a zeroed out q->elevator pointer. The two existing in-kernel users don't do that. - It will only work at initialization time, since using the above two-staged construct does not properly quisce the queue. So add elevator_change() which takes care of this, and convert the elv_iosched_store() sysfs interface to use this helper as well.

It is not immediately clear what this option causes to become ignored.
