A userspace program might want to know if an MPTCP connection fell back to TCP. If the subflows are managed by a daemon, the userspace program might just want to...
It is currently unsupported. The goal is to change the TTL in the IPv4 header and in the corresponding v6 option. As discussed at the last meeting, the best for...
`virtme` is no longer maintained. `virtme-ng` bring many new features, fixes and is quicker (e.g. using virtiofs, init script, microvm, etc.) and it is also used by the new Netdev...
MPC packets could be explicitly dropped or reset by firewall somewhere in the network, e.g. with: iptables -t filter -A FORWARD -p tcp --tcp-option 30 -j DROP It sounds safer...
As reported by Paolo at the last meeting, Packetdrill can coalesce some TCP packets, but it can be problematic: it ignores MPTCP options, aggregate packets that are not continuous from...
We don't have a clear documentation and guidance for users. It is missing and we can see that by looking at the recent tickets we got from users. It might...
A kernel panic has been detected by the [CI](https://github.com/multipath-tcp/mptcp_net-next/actions/runs/7505454949/job/20434726552) (no debug kconfig). Click to expand but probably ignore this one, no debug info # INFO: validating network environment with pings...
Mainly according to [NIPA](https://netdev.bots.linux.dev/flakes.html?br-cnt=88&tn-needle=mptcp) (history [normal](https://netdev.bots.linux.dev/contest.html?executor=vmksft-mptcp) - [debug](https://netdev.bots.linux.dev/contest.html?executor=vmksft-mptcp-dbg)), this test is unstable. It looks like we can see the instability with and without unbalanced delay, but mainly with. In NIPA,...
Now that we have these counters from #385 showing the amount of bytes that have been transmitted: ```c __u64 mptcpi_bytes_retrans; __u64 mptcpi_bytes_sent; __u64 mptcpi_bytes_received; __u64 mptcpi_bytes_acked; ``` We can probably...
**If** there is a use-case, it might be good to expose the last time "an action happened", similar to the ones exposed with TCP: ```c info->tcpi_last_data_sent = jiffies_to_msecs(now - tp->lsndtime);...
