2016-10-18bridge: multicast: restore perm router ports on multicast enableNikolay Aleksandrov
Satish reported a problem with the perm multicast router ports not getting reenabled after some series of events, in particular if it happens that the multicast snooping has been disabled and the port goes to disabled state then it will be deleted from the router port list, but if it moves into non-disabled state it will not be re-added because the mcast snooping is still disabled, and enabling snooping later does nothing. Here are the steps to reproduce, setup br0 with snooping enabled and eth1 added as a perm router (multicast_router = 2): 1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping 2. $ ip l set eth1 down ^ This step deletes the interface from the router list 3. $ ip l set eth1 up ^ This step does not add it again because mcast snooping is disabled 4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping 5. $ bridge -d -s mdb show <empty> At this point we have mcast enabled and eth1 as a perm router (value = 2) but it is not in the router list which is incorrect. After this change: 1. $ echo 0 > /sys/class/net/br0/bridge/multicast_snooping 2. $ ip l set eth1 down ^ This step deletes the interface from the router list 3. $ ip l set eth1 up ^ This step does not add it again because mcast snooping is disabled 4. $ echo 1 > /sys/class/net/br0/bridge/multicast_snooping 5. $ bridge -d -s mdb show router ports on br0: eth1 Note: we can directly do br_multicast_enable_port for all because the querier timer already has checks for the port state and will simply expire if it's in blocking/disabled. See the comment added by commit 9aa66382163e7 ("bridge: multicast: add a comment to br_port_state_selection about blocking state") Fixes: 561f1103a2b7 ("bridge: Add multicast_snooping sysfs toggle") Reported-by: Satish Ashok <sashok@cumulusnetworks.com> Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.

2016-10-18net: Introduce new api for walking upper and lower devicesDavid Ahern
This patch introduces netdev_walk_all_upper_dev_rcu, netdev_walk_all_lower_dev and netdev_walk_all_lower_dev_rcu. These functions recursively walk the adj_list of devices to determine all upper and lower devices. The functions take a callback function that is invoked for each device in the list. If the callback returns non-0, the walk is terminated and the functions return that code back to callers. v3 - simplified netdev_has_upper_dev_all_rcu and __netdev_has_upper_dev and removed typecast as suggested by Stephen v2 - fixed definition of netdev_next_lower_dev_rcu to mirror the upper_dev version.

This macro's last use was removed in commit d769ef81d5b59 ("RDS: Update rds_conn_shutdown to work with rds_conn_path") so make the macro and the __rds_conn_error function definition and declaration disappear.

2016-10-17net: pktgen: remove rcu locking in pktgen_change_name()Eric Dumazet
After Jesper commit back in linux-3.18, we trigger a lockdep splat in proc_create_data() while allocating memory from pktgen_change_name(). This patch converts t->if_lock to a mutex, since it is now only used from control path, and adds proper locking to pktgen_change_name() 1) pktgen_thread_lock to protect the outer loop (iterating threads) 2) t->if_lock to protect the inner loop (iterating devices) Note that before Jesper patch, pktgen_change_name() was lacking proper protection, but lockdep was not able to detect the problem.

2016-10-17ila: Don't use dest cache when gateway is setTom Herbert
If the gateway is set on an ILA route we don't need to bother with using the destination cache in the ILA route. Translation does not change the routing in this case so we can stick with orig_output in the lwstate output function. Tested: Ran netperf with and without gateway for LWT route.
