mac_pton() parses MAC address in form XX:XX:XX:XX:XX:XX and only in that form. mac_pton() doesn't dirty result until it's sure string representation is valid. mac_pton() doesn't care about characters _after_ last octet, it's up to caller to deal with it. mac_pton() diverges from 0/-E return value convention. Target usage: if (!mac_pton(str, whatever->mac)) return -EINVAL; /* ->mac being u8 [ETH_ALEN] is filled at this point. */ /* optionally check str[3 * ETH_ALEN - 1] for termination */ Use mac_pton() in pktgen and netconsole for start.

At VLAN dismantle phase, unregister_vlan_dev() makes one synchronize_net() call after vlan_group_set_device(grp, vlan_id, NULL). This call can be safely removed because we are calling unregister_netdevice_queue() to queue device for deletion, and this process needs at least one rcu grace period to complete.

veth devices dont use the batched device unregisters yet. Since veth are a pair of devices, it makes sense to use a batch of two unregisters, this roughly divides dismantle time by two. Fix this by changing dellink() callers to always provide a non NULL head. (Idea from Michał Mirosław) This patch also handles macvlan case : We now dismantle all macvlans on top of a lower dev at once.

We have two cases. Either the socket is in TCP_ESTABLISHED state and connect() filled in the inet socket cork flow, or we looked up the route here and used an on-stack flow. Track which one it was, and use it to obtain src/dst addrs. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch enables ethtool to set the loopback mode on a given interface. By configuring the interface in loopback mode in conjunction with a policy route / rule, a userland application can stress the egress / ingress path exposing the flows of the change in progress and potentially help developer(s) understand the impact of those changes without even sending a packet out on the network. Following set of commands illustrates one such example - a) ip -4 addr add 192.168.1.1/24 dev eth1 b) ip -4 rule add from all iif eth1 lookup 250 c) ip -4 route add local 0/0 dev lo proto kernel scope host table 250 d) arp -Ds 192.168.1.100 eth1 e) arp -Ds 192.168.1.200 eth1 f) sysctl -w net.ipv4.ip_nonlocal_bind=1 g) sysctl -w net.ipv4.conf.all.accept_local=1 # Assuming that the machine has 8 cores h) taskset 000f netserver -L 192.168.1.200 i) taskset 00f0 netperf -t TCP_CRR -L 192.168.1.100 -H 192.168.1.200 -l 30 Signed-off-by: NMahesh Bandewar <maheshb@google.com> Acked-by: NBen Hutchings <bhutchings@solarflare.com> Signed-off-by: NDavid S.

This allows us to acquire the exact route keying information from the protocol, however that might be managed. It handles all of the possibilities, from the simplest case of storing the key in inet->cork.fl to the more complex setup SCTP has where individual transports determine the flow.

This is just like inet_csk_route_req() except that it operates after we've created the new child socket. In this way we can use the new socket's cork flow for proper route key storage. This will be used by DCCP and TCP child socket creation handling. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

All invokers of ip_queue_xmit() must make certain that the socket is locked. All of SCTP, TCP, DCCP, and L2TP now make sure this is the case. Therefore we can use the cork flow during output route lookup in ip_queue_xmit() when the socket route check fails. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

l2tp_xmit_skb() must take the socket lock. It makes use of ip_queue_xmit() which expects to execute in a socket atomic context. Since we execute this function in software interrupts, we cannot use the usual lock_sock()/release_sock() sequence, instead we have to use bh_lock_sock() and see if a user has the socket locked, and if so drop the packet.

Both l2tp_ip_connect() and l2tp_ip_sendmsg() must take the socket lock. They both modify socket state non-atomically, and in particular l2tp_ip_sendmsg() increments socket private counters without using atomic operations. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The hard_if_event is called by the notifier with rtnl_lock and tries to remove sysfs entries when a NETDEV_UNREGISTER event is received. This will automatically take the s_active lock. The s_active lock is also used when a new interface is added to a meshif through sysfs. In that situation we cannot wait for the rntl_lock before creating the actual batman-adv interface to prevent a deadlock. It is still possible to try to get the rtnl_lock and immediately abort the current operation when the trylock call failed. Signed-off-by: NSven Eckelmann <sven@narfation.org>

hardif_list_lock is unneccessary because we already ensure that no multiple admin operations can take place through rtnl_lock. hardif_list_lock only adds additional overhead and complexity. Critical functions now check whether they are called with rtnl_lock using ASSERT_RTNL. It indirectly fixes the problem that orig_hash_del_if() expects that only one interface is deleted from hardif_list at a time, but hardif_remove_interfaces() removes all at once and then calls orig_hash_del_if().

The bridge loop detection for batman-adv allows the bat0 interface to be bridged into an ethernet segment which other batman-adv nodes are connected to.
