Patch "af_rose/x25: Sanity check the maximum user frame size" (commit 83e0bbcb) from Alan Cox got locking wrong. If we bail out due to user frame size being too large, we must unlock the socket beforehand. Signed-off-by: NJean Delvare <jdelvare@suse.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

A zero length frame filter was recently introduced in ROSE protocole. Previous commit makes the same at AX25 protocole level. This patch has the same purpose for NetRom protocole. The reason is that empty frames have no meaning in NetRom protocole. Signed-off-by: NBernard Pidoux <f6bvp@amsat.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.

In nr_release(), one code path calls sock_orphan() which will NULL out sk->sk_socket already. In the other case, handling states other than NR_STATE_{0,1,2,3}, seems to not be possible other than due to bugs. Even for an uninitialized nr->state value, that would be zero or NR_STATE_0. It might be wise to stick a WARN_ON() here. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: NEric W. Biederman <ebiederm@xmission.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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.

This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

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.
