[ Upstream commit 1233898ab758cbcf5f6fea10b8dd16a0b2c24fab ] The mirror_gre_scale test creates as many ERSPAN sessions as the underlying chip supports, and tests that they all work. In order to determine that it issues a stream of ICMP packets and checks if they are mirrored as expected. However, the mausezahn invocation missed the -6 flag to identify the use of IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to ICMP6. It also didn't pass an explicit source IP address, which apparently worked at some point in the past, but does not anymore. To fix these issues, extend the function mirror_test() in mirror_lib by detecting the IPv6 protocol addresses, and using a different ICMP scheme. Fix __mirror_gre_test() in the selftest itself to pass a source IP address. Signed-off-by: Petr Machata <petrm@nvidia.com> Signed-off-by: David S.

[ Upstream commit 5888a61cb4e00695075bbacfd86f3fa73af00413 ] 'mptcp_connect' already has a timeout for poll() but in some cases, it is not enough. With "timeout" tool, we will force the command to fail if it doesn't finish on time. Thanks to that, the script will continue and display details about the current state before marking the test as failed. Displaying this state is very important to be able to understand the issue. Best to have our CI reporting the issue than just "the test hanged". Note that in mptcp_connect.sh, we were using a long timeout to validate the fact we cannot create a socket if a sysctl is set. We don't need this timeout. In diag.sh, we want to send signals to mptcp_connect instances that have been started in the netns. But we cannot send this signal to 'timeout' otherwise that will stop the timeout and messages telling us SIGUSR1 has been received will be printed. Instead of trying to find the right PID and storing them in an array, we can simply use the output of 'ip netns pids' which is all the PIDs we want to send signal to.

[ Upstream commit c8d0260cdd96fdccdef0509c4160e28a1012a5d7 ]
The FDB roaming test installs a destination MAC address on the wrong
interface of an FDB database and tests whether the mirroring fails, because
packets are sent to the wrong port. The test by mistake installs the FDB
entry as local. This worked previously, because drivers were notified of
local FDB entries in the same way as of static entries. However that has
been fixed in the commit 6ab4c3117aec ("net: bridge: don't notify switchdev
for local FDB addresses"), and local entries are not notified anymore. As a
result, the HW is not reconfigured for the FDB roam, and mirroring keeps
working, failing the test.
To fix the issue, mark the FDB entry as static.

Test that all possible combinations of inner and outer ECN bits result in the correct inner ECN marking according to RFC 6040 4.2. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
The ECN bit defines ECT(1) = 1, ECT(0) = 2. So inner 0x02 + outer 0x01
should be inner ECT(0) + outer ECT(1). Based on the description of
__INET_ECN_decapsulate, the final decapsulate value should be
ECT(1). So fix the test expect value to 0x01.
Before the fix:
TEST: VXLAN: ECN decap: 01/02->0x02 [FAIL]
Expected to capture 10 packets, got 0.
After the fix:
TEST: VXLAN: ECN decap: 01/02->0x01 [ OK ]

The join self tests previously used the '-c' command line option to

option.
Restore the capture functionality with '-c' and move the syncookie test
option to '-k'.

When mirroring to a gretap in hardware the device expects to be
programmed with the egress port and all the encapsulating headers. This
requires the driver to resolve the path the packet will take in the
software data path and program the device accordingly.
If the path cannot be resolved (in this case because of an unresolved
neighbor), then mirror installation fails until the path is resolved.
This results in a race that causes the test to sometimes fail.
Fix this by setting the neighbor's state to permanent, so that it is
always valid.
