2018-11-24selftests/net: add txring_overwriteWillem de Bruijn
Packet sockets with PACKET_TX_RING send skbs with user data in frags. Before commit 5cd8d46ea156 ("packet: copy user buffers before orphan or clone") ring slots could be released prematurely, possibly allowing a process to overwrite data still in flight. This test opens two packet sockets, one to send and one to read. The sender has a tx ring of one slot. It sends two packets with different payload, then reads both and verifies their payload. Before the above commit, both receive calls return the same data as the send calls use the same buffer. From the commit, the clone needed for looping onto a packet socket triggers an skb_copy_ubufs to create a private copy. The separate sends each arrive correctly.

commit 3327a9c46352f1 ("selftests: add functionals test for UDP GRO") make use of ipv6 NAT, but such a feature is not currently implied by selftests. Since the 'ip[6]tables' commands may actually create nft rules, depending on the specific user-space version, let's pull both NF and NFT nat modules plus the needed deps.

This skeleton sets up a topology with three VXLAN endpoints: one "local", possibly offloaded, and two "remote", formed using veth pairs and likely purely software bridges. The "local" endpoint is connected to host systems by a VLAN-unaware bridge. Since VXLAN tunnels must be unique per namespace, each of the "remote" endpoints is in its own namespace.

2018-11-19selftests: forwarding: lib: Add in_ns()Petr Machata
In order to run a certain command inside another network namespace, it's possible to use "ip netns exec ns command". However then one can't use functions defined in lib.sh or a test suite. One option is to do "ip netns exec ns bash -c command", provided that all functions that one wishes to use (and their dependencies) are published using "export -f". That may not be practical. Therefore, introduce a helper in_ns(), which wraps a given command in a boilerplate of "ip netns exec" and "source lib.sh", thus making all library functions available. (Custom functions that a script wishes to run within a namespace still need to be exported.) Because quotes in "$@" aren't recognized in heredoc, hand-expand the array in an explicit for loop, leveraging printf %q to handle proper quoting.

2018-11-19selftests: forwarding: lib: Support NUM_NETIFS of 0Petr Machata
So far the case of NUM_NETIFS of 0 has not been interesting. However if one wishes to reuse the lib.sh routines in a setup of a separate namespace, being able to import like this is handy. Therefore replace the {1..$NUM_NETIFS} references, which cause iteration over 1 and 0, with an explicit for loop like we do in setup_wait() and tc_offload_check(), so that for NUM_NETIFS of 0 no iteration is done.

2018-10-24net/ipv6: Allow onlink routes to have a device mismatch if it is the default ↵David Ahern
route The intent of ip6_route_check_nh_onlink is to make sure the gateway given for an onlink route is not actually on a connected route for a different interface (e.g., 2001:db8:1::/64 is on dev eth1 and then an onlink route has a via 2001:db8:1::1 dev eth2). If the gateway lookup hits the default route then it most likely will be a different interface than the onlink route which is ok. Update ip6_route_check_nh_onlink to disregard the device mismatch if the gateway lookup hits the default route. Turns out the existing onlink tests are passing because there is no default route or it is an unreachable default, so update the onlink tests to have a default route other than unreachable.

Immediately after mlxsw module is probed and lldpad started, added APP entries are briefly in "unknown" state before becoming "pending". That's the state that lldpad_app_wait_set() typically sees, and since there are no pending entries at that time, it bails out. However the entries have not been pushed to the kernel yet at that point, and thus the test case fails. Fix by waiting for both unknown and pending entries to disappear before proceeding.
