2017-09-01mlxsw: spectrum_router: Set abort trap in all virtual routersIdo Schimmel
When the abort mechanism is invoked a default route directing packets to the CPU is programmed in all the virtual routers currently in use. This can result in packet loss in case a new VRF is configured. Upon abort, program the default route in all virtual routers, whether they are in use or not. The patch is directed at net-next since post-abort fixes aren't critical and packet loss due to a missing default route will be insignificant compared to packet loss caused by the CPU port policer.

2017-09-01mlxsw: spectrum_router: Trap packets hitting anycast routesIdo Schimmel
I relied on the fact that anycast routes use the loopback device as their nexthop device to trap packets hitting them to the CPU. After commit 4832c30d5458 ("net: ipv6: put host and anycast routes on device with address") this is no longer the case and such routes are programmed with a forward action (note the 'offload' flag): anycast cafe:: dev enp3s0np7 proto kernel metric 0 offload pref medium This will prevent the router from locally receiving packets destined to the Subnet-Router anycast address. Fix this by specifically programming anycast routes with action trap, which results in the following output: anycast cafe:: dev enp3s0np7 proto kernel metric 0 pref medium Fixes: 4832c30d5458 ("net: ipv6: put host and anycast routes on device with address") Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2017-09-01mlxsw: spectrum: Forbid linking to devices that have uppersIdo Schimmel
The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the device in case a port is enslaved to a master netdev such as bridge or bond. Since the driver ignores events unrelated to its ports and their uppers, it's possible to engineer situations in which the device's data path differs from the kernel's. One example to such a situation is when a port is enslaved to a bond that is already enslaved to a bridge. When the bond was enslaved the driver ignored the event - as the bond wasn't one of its uppers - and therefore a bridge port instance isn't created in the device. Until such configurations are supported forbid them by checking that the upper device doesn't have uppers of its own.

2017-09-01bpf: Only set node->ref = 1 if it has not been setMartin KaFai Lau
This patch writes 'node->ref = 1' only if node->ref is 0. The number of lookups/s for a ~1M entries LRU map increased by ~30% (260097 to 343313). Other writes on 'node->ref = 0' is not changed. In those cases, the same cache line has to be changed anyway.

2017-09-01bpf: Inline LRU map lookupMartin KaFai Lau
Inline the lru map lookup to save the cost in making calls to bpf_map_lookup_elem() and htab_lru_map_lookup_elem(). Different LRU hash size is tested. The benefit diminishes when the cache miss starts to dominate in the bigger LRU hash. Considering the change is simple, it is still worth to optimize.

2017-09-01bpf: Add lru_hash_lookup performance testMartin KaFai Lau
Create a new case to test the LRU lookup performance. At the beginning, the LRU map is fully loaded (i.e. the number of keys is equal to map->max_entries). The lookup is done through key 0 to num_map_entries and then repeats from 0 again.
