Fix up remaining drivers returning a magic or an errno value from their ndo_start_xmit() functions that were missed in the first pass: - isdn_net: missed conversion - bpqether: missed conversion: skb is freed, so return NETDEV_TX_OK - hp100: intention appears to be to resubmit skb once resources are available, but due to no queue handling it is dropped for now. - lapbether: skb is freed, so return NETDEV_TX_OK Signed-off-by: NPatrick McHardy <kaber@trash.net> Signed-off-by: NDavid S.

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.

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 modifies every packet receive function registered with dev_add_pack() to drop packets if they are not from the initial network namespace.

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.

The rcu_dereference() primitive needs to be applied to an l-value in order to ensure that compiler writers don't get an opportunity to apply reordering optimizations that could result in multiple fetches or in other misbehavior. This patch pulls the rcu_dereference() calls in bpq_seq_next() up to the point at which the fetched pointers are still l-values, rather than after list_entry() has transformed them into r-values.

From Suzanne Wood <suzannew@cs.pdx.edu>: Clarify RCU implementation in bpqether.c. Because bpq_new_device() calls list_add_rcu() and bpq_free_device() calls list_del_rcu(), substitute list_for_each_entry_rcu() for list_for_each_entry() in bpq_get_ax25_dev() and in bpq_seq_start(). Add rcu dereference protection in bpq_seq_next(). The rcu_read_lock()/unlock() in bpq_device_event() are removed because netdev event handlers are called with RTNL locking in place. FYI: bpq_free_device() calls list_del_rcu() which, per list.h, requires synchronize_rcu() which can block or call_rcu() or call_rcu_bh() which cannot block. Herbert Xu notes that synchronization is done here by unregister_netdevice(). This calls synchronize_net() which in turn uses synchronize_rcu().

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!
