Re: 2.6.11-rc2 TCP ignores PMTU ICMP (Re: Linux 2.6.11-rc2)

I just got an interesting "I see these problems too" report.  It
may provide a useful clue.  According to "Art Haas" [off-list ref]:

I'm running the current BK kernel now, and I'm not seeing the problems
right now because, I found, I do not have some of the IP masquerading
modules installed on my machine. When these modules get installed then
the cvs/rsync problems appear. 

 
I do have CONFIG_IP_NF_TARGET_MASQUERADE=y on the system where I'm
seeing this, though it's not doing anything just now.  Haven't yet
made time to see if disabling it improves things ... but if that's
a factor, it could explain why more people aren't suffering with
this problem.
