2 daysselftests: mptcp: connect: also cover checksumMatthieu Baerts (NGI0)
commit fdf0f60a2bb02ba581d9e71d583e69dd0714a521 upstream. The checksum mode has been added a while ago, but it is only validated when manually launching mptcp_connect.sh with "-C". The different CIs were then not validating these MPTCP Connect tests with checksum enabled. To make sure they do, add a new test program executing mptcp_connect.sh with the checksum mode.

commit 37848a456fc38c191aedfe41f662cc24db8c23d9 upstream. The "mmap" and "sendfile" alternate modes for mptcp_connect.sh/.c are available from the beginning, but only tested when mptcp_connect.sh is manually launched with "-m mmap" or "-m sendfile", not via the kselftests helpers. The MPTCP CI was manually running "mptcp_connect.sh -m mmap", but not "-m sendfile". Plus other CIs, especially the ones validating the stable releases, were not validating these alternate modes. To make sure these modes are validated by these CIs, add two new test programs executing mptcp_connect.sh with the alternate modes.

2025-07-17selftests: net: lib: Move logging from forwarding/lib.sh herePetr Machata
[ Upstream commit b219bcfcc92e9bd50c6277ac68cb75f64b403e5e ] Many net selftests invent their own logging helpers. These really should be in a library sourced by these tests. Currently forwarding/lib.sh has a suite of perfectly fine logging helpers, but sourcing a forwarding/ library from a higher-level directory smells of layering violation. In this patch, move the logging helpers to net/lib.sh so that every net test can use them. Together with the logging helpers, it's also necessary to move pause_on_fail(), and EXIT_STATUS and RET. Existing lib.sh users might be using these same names for their functions or variables. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

2025-05-29bridge: mdb: Allow replace of a host-joined groupPetr Machata
[ Upstream commit d9e9f6d7b7d0c520bb87f19d2cbc57aeeb2091d5 ] Attempts to replace an MDB group membership of the host itself are currently bounced: # ip link add name br up type bridge vlan_filtering 1 # bridge mdb replace dev br port br grp 239.0.0.1 vid 2 # bridge mdb replace dev br port br grp 239.0.0.1 vid 2 Error: bridge: Group is already joined by host. A similar operation done on a member port would succeed. Ignore the check for replacement of host group memberships as well. The bit of code that this enables is br_multicast_host_join(), which, for already-joined groups only refreshes the MC group expiration timer, which is desirable; and a userspace notification, also desirable. Change a selftest that exercises this code path from expecting a rejection to expecting a pass. The rest of MDB selftests pass without modification.

[ Upstream commit 7d3f3b4367f315a61fc615e3138f3d320da8c466 ] Check number of paths by fib_info_num_path(), and update_or_create_fnhe() for every path. Problem is that pmtu is cached only for the oif that has received icmp message "need to frag", other oifs will still try to use "default" iface mtu. An example topology showing the problem: | host1 +---------+ | dummy0 | 10.179.20.18/32 mtu9000 +---------+ +-----------+----------------+ +---------+ +---------+ | ens17f0 | 10.179.2.141/31 | ens17f1 | 10.179.2.13/31 +---------+ +---------+ | (all here have mtu 9000) | +------+ +------+ | ro1 | 10.179.2.140/31 | ro2 | 10.179.2.12/31 +------+ +------+ | | ---------+------------+-------------------+------ | +-----+ | ro3 | 10.10.10.10 mtu1500 +-----+ | ======================================== some networks ======================================== | +-----+ | eth0| 10.10.30.30 mtu9000 +-----+ | host2 host1 have enabled multipath and sysctl net.ipv4.fib_multipath_hash_policy = 1: default proto static src 10.179.20.18 nexthop via 10.179.2.12 dev ens17f1 weight 1 nexthop via 10.179.2.140 dev ens17f0 weight 1 When host1 tries to do pmtud from 10.179.20.18/32 to host2, host1 receives at ens17f1 iface an icmp packet from ro3 that ro3 mtu=1500. And host1 caches it in nexthop exceptions cache. Problem is that it is cached only for the iface that has received icmp, and there is no way that ro3 will send icmp msg to host1 via another path. Host1 now have this routes to host2: ip r g 10.10.30.30 sport 30000 dport 443 10.10.30.30 via 10.179.2.12 dev ens17f1 src 10.179.20.18 uid 0 cache expires 521sec mtu 1500 ip r g 10.10.30.30 sport 30033 dport 443 10.10.30.30 via 10.179.2.140 dev ens17f0 src 10.179.20.18 uid 0 cache So when host1 tries again to reach host2 with mtu>1500, if packet flow is lucky enough to be hashed with oif=ens17f1 its ok, if oif=ens17f0 it blackholes and still gets icmp msgs from ro3 to ens17f1, until lucky day when ro3 will send it through another flow to ens17f0.

2025-02-17selftests: mptcp: connect: -f: no reconnectMatthieu Baerts (NGI0)
commit 5368a67307b3b2c347dc8965ac55b888be665934 upstream. The '-f' parameter is there to force the kernel to emit MPTCP FASTCLOSE by closing the connection with unread bytes in the receive queue. The xdisconnect() helper was used to stop the connection, but it does more than that: it will shut it down, then wait before reconnecting to the same address. This causes the mptcp_join's "fastclose test" to fail all the time. This failure is due to a recent change, with commit 218cc166321f ("selftests: mptcp: avoid spurious errors on disconnect"), but that went unnoticed because the test is currently ignored. The recent modification only shown an existing issue: xdisconnect() doesn't need to be used here, only the shutdown() part is needed.

But the kernel currently dismisses GSO requests only after checking MTU/PMTU on gso_size. This means any packets, regardless of their payload sizes, could be dropped when PMTU becomes smaller than requested gso_size. We encountered this issue in production and it caused a reliability problem that new QUIC connection cannot be established before PMTU cache expired, while non GSO sockets still worked fine at the same time. Ideally, do not check any GSO related constraints when payload size is smaller than requested gso_size, and return EMSGSIZE instead of EINVAL on MTU/PMTU check failure to be more specific on the error cause.

2024-12-05ipv6: Fix soft lockups in fib6_select_path under high next hop churnOmid Ehtemam-Haghighi
[ Upstream commit d9ccb18f83ea2bb654289b6ecf014fd267cc988b ] Soft lockups have been observed on a cluster of Linux-based edge routers located in a highly dynamic environment. Using the `bird` service, these routers continuously update BGP-advertised routes due to frequently changing nexthop destinations, while also managing significant IPv6 traffic. The lockups occur during the traversal of the multipath circular linked-list in the `fib6_select_path` function, particularly while iterating through the siblings in the list. The issue typically arises when the nodes of the linked list are unexpectedly deleted concurrently on a different core—indicated by their 'next' and 'previous' elements pointing back to the node itself and their reference count dropping to zero. This results in an infinite loop, leading to a soft lockup that triggers a system panic via the watchdog timer. Apply RCU primitives in the problematic code sections to resolve the issue. Where necessary, update the references to fib6_siblings to annotate or use the RCU APIs. Include a test script that reproduces the issue. The script periodically updates the routing table while generating a heavy load of outgoing IPv6 traffic through multiple iperf3 clients. It consistently induces infinite soft lockups within a couple of minutes.

This is done so we can cover different combinations (large mtu on client, small on server, link has lowest mtu, etc). Furthermore, file size is random, even for the first run. Rework this script and always use the same file size on initial run so that at least the first round can be expected to have reproducible behavior. Second round will use random mtu/filesize. Raise the failure limit to that of the file size, this should avoid all errneous test errors. Currently, first fin will remove the offload, so if one peer is already closing remaining data is handled by classic path, which result in larger-than-expected counter and a test failure. Given packet path also counts tcp/ip headers, in case offload is completely broken this test will still fail (as expected). The test counter limit could be made more strict again in the future once flowtable can keep a connection in offloaded state until FINs in both directions were seen.

The one_bridge_two_pvids() test intends to check that there is no leakage of traffic between bridge ports which have a single VLAN - the PVID VLAN. Because of a typo, port $swp1 is configured with a PVID twice (second command overwrites first), and $swp2 isn't configured at all (and since the bridge vlan_default_pvid property is set to 0, this port will not have a PVID at all, so it will drop all untagged and priority-tagged traffic). So, instead of testing the configuration that was intended, we are testing a different one, where one port has PVID 2 and the other has no PVID. This incorrect version of the test should also pass, but is ineffective for its purpose, so fix the typo. This typo has an impact on results of the test, potentially leading to wrong conclusions regarding the functionality of a network device. The tests results: TEST: Switch ports in VLAN-aware bridge with different PVIDs: Unicast non-IP untagged [ OK ] Multicast non-IP untagged [ OK ] Broadcast non-IP untagged [ OK ] Unicast IPv4 untagged [ OK ] Multicast IPv4 untagged [ OK ] Unicast IPv6 untagged [ OK ] Multicast IPv6 untagged [ OK ] Unicast non-IP VID 1 [ OK ] Multicast non-IP VID 1 [ OK ] Broadcast non-IP VID 1 [ OK ] Unicast IPv4 VID 1 [ OK ] Multicast IPv4 VID 1 [ OK ] Unicast IPv6 VID 1 [ OK ] Multicast IPv6 VID 1 [ OK ] Unicast non-IP VID 4094 [ OK ] Multicast non-IP VID 4094 [ OK ] Broadcast non-IP VID 4094 [ OK ] Unicast IPv4 VID 4094 [ OK ] Multicast IPv4 VID 4094 [ OK ] Unicast IPv6 VID 4094 [ OK ] Multicast IPv6 VID 4094 [ OK ] Fixes: 476a4f05d9b8 ("selftests: forwarding: add a no_forwarding.sh test") Reviewed-by: Hangbin Liu <liuhangbin@gmail.com> Reviewed-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Kacper Ludwinski <kac.ludwinski@icloud.com> Link: https://patch.msgid.link/20241002051016.849-1-kac.ludwinski@icloud.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
