I finally got around to testing this issue with an upstream kernel. I used the latest version, 4.5.0-040500rc4-generic. The bug still exists in that version of the kernel.
Sorry it took so long for me to get around to this; I'm a college student and I've been really busy with classes for the past few weeks. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1536861 Title: Simultaneous TCP Open does not work correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1536861/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
