Hi,
Some days ago I reported a PMTU bug I observed:
+------------------------------------------------ | I think I have found a Path MTU Discovery bug in Linux-2.2.7-ac1. | | 1. Linux sends a packet > PMTU | 2. "ICMP Host Unreachable - need to frag" received | 3. PMTU-sized packet is sent | 4. data which comes after the packet from 1. is sent in PMTU-sized | packets. | | The problem is that the data remaining in the packet 1. which comes after | the PMTU length is never resent. So the TCP connection stalls at this point. +------------------------------------------------
I just re-tested with Linux-2.2.7-ac2: the same thing happens. The problem is easily reproducable.
SysInfo: -------- dual CPU AlphaServer 2000 4/200, Linux-2.2.7-ac2 SMP, well maintained Red Hat 5.2 / Alpha egcs-1.0.3a compiler (the one that comes with RH 5.2: there is no gcc in RH 5.2 / Alpha)
Greetings, Rob van Nieuwkerk
