I noticed this first with 1.1.76. Someone reported this in 1.1.85
and it is still there in 1.1.88.
These "tcp.c:tcp_data bug acked < copied" messages are rare (usually
only once or twice a week on a loaded system). That's why I can't
tell if this is fixed in 1.1.90 - if I upgrade to 1.1.90, the bug
will probably not manifest itself until 1.1.92 is released... :-)
Everything seems to work fine, but the message contains the word "bug"
so I report it here... Alan?
Another problem: the routing table becomes full of never used routes
to network addresses, but with incorrect netmask (255.255.255.255).
I guess this has something to do with ICMP NET REDIRECT handling...
Most of these routes are redundant (the gateway is the same as the
default one) and maybe they shouldn't be added at all?
If it helps: at least some of these subnets should have netmasks
like 255.255.255.224 (not on byte boundaries).
This long routing table doesn't seem to cause any problems so far,
but I guess it may take longer to find the correct route (for every
packet) in such a large table... (150+ entries after few days up)
If this is a bug, are there any chances of fixing it before 1.2?
Or am I missing something? Maybe it is a feature, not a bug? :-)
