https://bugzilla.kernel.org/show_bug.cgi?id=219129 --- Comment #6 from Jordan Whited (jordan@xxxxxxxxxxxxxxxx) --- https://github.com/jwhited/tun-einval-repro/blob/main/main.go contains a simplified reproduction of the issue. This writes a GSO_TCPv4 packet to a TUN device w/GSO=1240 and 2 equal length segments. The write returns EINVAL with e269d79c7d35aa3808b1f3c1737d63dab504ddc8 absent the fix in 89add40066f9ed9abe5f7f886fe5789ff7e0c50e. -- You may reply to this email to add a comment.
