If the iucv_path_connect() call fails then return an error code that corresponds to the iucv_path_connect() failure condition; instead of returning -ECONNREFUSED for any failure. This helps to improve error handling for user space applications (e.g. inform the user that the z/VM guest is not authorized to connect to other guest virtual machines). The error return codes are based on those described in connect(2).

The loop in iucv_callback_txdone presumes existence of an entry with msg->tag in the send_skb_q list. In error cases this assumption might be wrong and might cause an endless loop. Loop is rewritten to guarantee loop end in case of missing msg->tag entry in send_skb_q. Signed-off-by: NUrsula Braun <braunu@de.ibm.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Many-many code in the kernel initialized the timer->function and timer->data together with calling init_timer(timer). There is already a helper for this. Use it for networking code. The patch is HUGE, but makes the code 130 lines shorter (98 insertions(+), 228 deletions(-)).

Finally, the zero_it argument can be completely removed from the callers and from the function prototype. Besides, fix the checkpatch.pl warnings about using the assignments inside if-s. This patch is rather big, and it is a part of the previous one. I splitted it wishing to make the patches more readable. Hope this particular split helped.

AF_IUCV socket programs may waste Linux storage, because af_iucv allocates an skb whenever posted by the receive callback routine and receives the message immediately. Message receival is now postponed if data from previous callbacks has not yet been transferred to the receiving socket program. Instead a message handle is saved in a message queue as a reminder. Once messages could be given to the receiving socket program, there is an additional checking for entries in the message queue, followed by skb allocation and message receival if applicable.

This patch passes in the namespace a new socket should be created in and has the socket code do the appropriate reference counting. By virtue of this all socket create methods are touched. In addition the socket create methods are modified so that they will fail if you attempt to create a socket in a non-default network namespace. Failing if we attempt to create a socket outside of the default network namespace ensures that as we incrementally make the network stack network namespace aware we will not export functionality that someone has not audited and made certain is network namespace safe. Allowing us to partially enable network namespaces before all of the exotic protocols are supported. Any protocol layers I have missed will fail to compile because I now pass an extra parameter into the socket creation code.

With the inital implementation we missed to implement a skb backlog queue . The result is that socket receive processing tossed packets. Since AF_IUCV connections are working synchronously it leads to connection hangs. Problems with read, close and select also occured. Using a skb backlog queue is fixing all of these problems .

For the common, open coded 'skb->h.raw = skb->data' operation, so that we can later turn skb->h.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 cases: skb->h.raw = skb->data; skb->h.raw = {skb_push|[__]skb_pull}() The next ones will handle the slightly more "complex" cases.
