2009-10-14Phonet: routing table backendRémi Denis-Courmont1-6/+94
The Phonet "universe" only has 64 addresses, so we keep a trivial flat routing table. Signed-off-by: Rémi Denis-Courmont <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2009-09-30net: Make setsockopt() optlen be unsigned.David S. Miller1-1/+1
This provides safety against negative optlen at the type level instead of depending upon (sometimes non-trivial) checks against this sprinkled all over the the place, in each and every implementation. Based upon work done by Arjan van de Ven and feedback from Linus Torvalds. Signed-off-by: David S. Miller <[email protected]>

2009-09-24Phonet: fix race for port number in concurrent bind()Rémi Denis-Courmont1-8/+8
Allocating a port number to a socket and hashing that socket shall be an atomic operation with regards to other port allocation. Otherwise, we could allocate a port that is already being allocated to another socket. Signed-off-by: Rémi Denis-Courmont <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2009-09-24sysctl: remove "struct file *" argument of ->proc_handlerAlexey Dobriyan1-2/+2
It's unused. It isn't needed -- read or write flag is already passed and sysctl shouldn't care about the rest. It _was_ used in two places at arch/frv for some reason.

2009-09-11Phonet: back-end for autoconfigured addressesRémi Denis-Courmont1-1/+25
In some cases, the network device driver knows what layer-3 address the device should have. This adds support for the Phonet stack to automatically request from the driver and add that address to the network device.

2009-02-24netlink: change nlmsg_notify() return value logicPablo Neira Ayuso1-2/+3
This patch changes the return value of nlmsg_notify() as follows: If NETLINK_BROADCAST_ERROR is set by any of the listeners and an error in the delivery happened, return the broadcast error; else if there are no listeners apart from the socket that requested a change with the echo flag, return the result of the unicast notification. Thus, with this patch, the unicast notification is handled in the same way of a broadcast listener that has set the NETLINK_BROADCAST_ERROR socket flag. This patch is useful in case that the caller of nlmsg_notify() wants to know the result of the delivery of a netlink notification (including the broadcast delivery) and take any action in case that the delivery failed. For example, ctnetlink can drop packets if the event delivery failed to provide reliable logging and state-synchronization at the cost of dropping packets. This patch also modifies the rtnetlink code to ignore the return value of rtnl_notify() in all callers. The function rtnl_notify() (before this patch) returned the error of the unicast notification which makes rtnl_set_sk_err() reports errors to all listeners. This is not of any help since the origin of the change (the socket that requested the echoing) notices the ENOBUFS error if the notification fails and should resync itself.
