Hi, While attempting to fix a PMTUD bug in 8.3-RELEASE-p4 that appears to now be resolved by r234342, I also came across r238516. It appears this fix only made it into 9/STABLE though, does anyone know why it wasn't brought back to 8? It's a fairly easy port, but I just wanted to confirm there wasn't something else at play I'm missing.
"If ip_output() returns EMSGSIZE to tcp_output(), then the latter calls tcp_mtudisc(), which in its turn may call tcp_output(). Under certain conditions (must admit they are very special) an infinite recursion can happen. To avoid recursion we can pass struct route to ip_output() and obtain correct mtu. This allows us not to use tcp_mtudisc() but call tcp_mss_update() directly."
