This patch makes two enhancements to the routine used to set bit fields within a TIPC message header: 1) It now ignores any bits of the new field value that are not covered by the mask being used. (Previously, if the new value exceeded the size of the mask the extra bits could corrupt other fields in the message header word being updated.) 2) The code has been optimized to minimize the number of run-time endianness conversion operations by leveraging the fact that the mask (and, in some cases, the value as well) is constant and the necessary conversion can be performed by the compiler.

The file net/tipc/port.c takes a lock using the function tipc_port_lock and then releases the lock sometimes using tipc_port_unlock and sometimes using spin_unlock_bh(p_ptr->publ.lock). tipc_port_unlock simply does the spin_unlock_bh, but it seems cleaner to use it everywhere. The problem was fixed using the following semantic patch. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ struct port *p_ptr; @@ p_ptr = tipc_port_lock(...) ...

This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: NEric W.

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 enhances TIPC's stream socket send routine so that it avoids transmitting data in chunks that require fragmentation and reassembly, thereby improving performance at both the sending and receiving ends of the connection. The "maximum packet size" hint that records MTU info allows the socket to decide how big a chunk it should send; in the event that the hint has become stale, fragmentation may still occur, but the data will be passed correctly and the hint will be updated in time for the following send. Note: The 66060 byte pseudo-MTU used for intra-node connections requires the send routine to perform an additional check to ensure it does not exceed TIPC"s limit of 66000 bytes of user data per chunk.

This patch simplifies TIPC's Ethernet receive routine to take advantage of information already present in each incoming sk_buff indicating whether the packet was explicitly sent to the interface, has been broadcast to all interfaces, or was picked up because the interface is in promiscous mode. This new approach also fixes the problem of TIPC accepting unwanted traffic through UML's multicast-based Ethernet interfaces (which deliver traffic in a promiscuous manner even if the interface is not configured to be promiscuous).
