2016-09-15net/sched: act_tunnel_key: Remove rcu_read_lock protectionHadar Hen Zion1-13/+4
Remove rcu_read_lock protection from tunnel_key_dump and use rtnl_dereference, dump operation is protected by rtnl lock. Also, remove rcu_read_lock from tunnel_key_release and use rcu_dereference_protected. Both operations are running exclusively and a writer couldn't modify t->params while those functions are executed.

Commit d5709f7ab776 ("flow_dissector: For stripped vlan, get vlan info from skb->vlan_tci") made flow dissector look at vlan_proto when vlan is present. Since test_bpf sets skb->vlan_tci to ~0 (including VLAN_TAG_PRESENT) we have to populate skb->vlan_proto.

2016-09-13net: bridge: add helper to call /sbin/bridge-stpVivien Didelot1-12/+31
If /sbin/bridge-stp is available on the system, bridge tries to execute it instead of the kernel implementation when starting/stopping STP. If anything goes wrong with /sbin/bridge-stp, bridge silently falls back to kernel STP, making hard to debug userspace STP. This patch adds a br_stp_call_user helper to start/stop userspace STP and debug errors from the program: abnormal exit status is stored in the lower byte and normal exit status is stored in higher byte. Below is a simple example on a kernel with dynamic debug enabled: # ln -s /bin/false /sbin/bridge-stp # brctl stp br0 on br0: failed to start userspace STP (256) # dmesg br0: /sbin/bridge-stp exited with code 1 br0: failed to start userspace STP (256) br0: using kernel STP Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in.
