The socket 2 bind the addr in use, bind should fail with EADDRINUSE. So if bind success or errno != EADDRINUSE, testcase should be failed.

selftests: forwarding: Add test cases for unresolved multicast routes

2022-09-20T15:22:15Z

Add IPv4 and IPv6 test cases for unresolved multicast routes, testing that queued packets are forwarded after installing a matching (S, G) route. The test cases can be used to reproduce the bugs fixed in "ipmr: Always call ip{,6}_mr_forward() from RCU read-side critical section". Signed-off-by: Ido Schimmel Signed-off-by: Jakub Kicinski

Merge tag 'io_uring-6.0-2022-09-02' of git://git.kernel.dk/linux-block

2022-09-02T23:37:01Z

Pull io_uring fixes from Jens Axboe: - A single fix for over-eager retries for networking (Pavel) - Revert the notification slot support for zerocopy sends. It turns out that even after more than a year or development and testing, there's not full agreement on whether just using plain ordered notifications is Good Enough to avoid the complexity of using the notifications slots. Because of that, we decided that it's best left to a future final decision. We can always bring back this feature, but we can't really change it or remove it once we've released 6.0 with it enabled. The reverts leave the usual CQE notifications as the primary interface for knowing when data was sent, and when it was acked.

selftests: forwarding: Fix failing tests with old libnet

2022-08-11T05:36:14Z

The custom multipath hash tests use mausezahn in order to test how changes in various packet fields affect the packet distribution across the available nexthops. The tool uses the libnet library for various low-level packet construction and injection. The library started using the "SO_BINDTODEVICE" socket option for IPv6 sockets in version 1.1.6 and for IPv4 sockets in version 1.2. When the option is not set, packets are not routed according to the table associated with the VRF master device and tests fail. Fix this by prefixing the command with "ip vrf exec", which will cause the route lookup to occur in the VRF routing table. This makes the tests pass regardless of the libnet library version.

selftests: mptcp: make sendfile selftest work

2022-08-05T07:51:29Z

When the selftest got added, sendfile() on mptcp sockets returned -EOPNOTSUPP, so running 'mptcp_connect.sh -m sendfile' failed immediately. This is no longer the case, but the script fails anyway due to timeout. Let the receiver know once the sender has sent all data, just like with '-m mmap' mode. v2: need to respect cfg_wait too, as pm_userspace.sh relied on -m sendfile to keep the connection open (Mat Martineau) Fixes: 048d19d444be ("mptcp: add basic kselftest for mptcp") Reported-by: Xiumei Mu Reviewed-by: Mat Martineau Signed-off-by: Florian Westphal Signed-off-by: Mat Martineau Signed-off-by: David S.
