[Bug 1736804] Re: No tcp_keepalive_time in LXD container

[Bug 1736804] Re: No tcp_keepalive_time in LXD container

The commit mentioned in comment #4 has been upstream since kernel v4.5. Marking the main linux task as fix released. ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to

I tested on 4.14 (Ubuntu) and 4.15 (Mainline) tcp_keepalive_time appears on both in new user namespaces. ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1736804
