Here is good summary of why using lgpl in apache product is not a great option: https://issues.apache.org/jira/browse/LEGAL-192?focusedCommentId=13907462=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-13907462 "These are not LEGAL restrictions. They are POLICY restrictions. They impact the downstream, not the ASF." My understanding that cilium and bcc legally can use existing libbpf, but they would have to provide non standard redistribution policy (apache2 plus lgpl 2.1 wording) which I suspect is not something cilium or bcc projects would want to do. So the best way forward is to dual license libbpf as lpgl 2.1 and apache2 -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[iovisor-dev] minutes: IO Visor TSC/Dev Meeting
Hi All, Thanks for joining the call today. Here are my notes! Cheers, Brenden === Discussion === Brenden: * 0.7.0 tag released to support 4.18 * Flaky test on fc26 - usdt3 - monitor and perhaps relax contraints in test Yonghong: * Discussing API for BTF support in kernel * prototyping currently the kernel interface * will need a few more weeks * Introspection improvements * Duplicating some ip/tc functionality into bpftool * Reason: want one integrated tool for all bpf introspection * Some debate about what the value of duplicating code is * Need to avoid too many tools * Lots of non-net users: cgroups, tc, xdp, perf * dual license libbpf to converge the code? Alexei: * bpf-next opened, swamped with code reviews Jiong: * 32 bit support * standalone flow control analyzer in progress * will try to remove extra config flags William: * AF_XDP for OVS * without zero copy driver, perf tests * > 3Mpps rx so far * working on port->port forwarding, with memcpy * needs zero-copy driver to improve tx speeds * will try with i40e driver === Attendees === Brenden Blanco Jakub Kicinski Jiong Wang Yonghong Song Jesper Brouer Alexei Starovoitov Joe Stringer Brendan Gregg William Tu JohnF -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Hi, Link regarding using LGPL with Apache licensed software, (from, https://www.apache.org/legal/resolved.html#category-x) ` WHICH LICENSES MAY NOT BE INCLUDED WITHIN APACHE PRODUCTS?¶ GNU LGPL The LGPL is ineligible primarily due to the restrictions it places on larger works, violating the third license criterion. ` Because we have a specific warning on the apache license site it seems best to get libbpf dual licensed. We would happily start using it in cilium[1] for example after the dual license was in place.
