[lwip-users] [lwip]bug in pcb->queuelen?

[address@hidden]

Hi everyone,

first of all many thanks to Adam for his great work.

I'm evaluating lwIP 0.5.0 for a network embeddded product. I ported it 
to 8051 platform using Keil 6.2. CS8900A as ethernet interface, 8 bit 
access. I know that lwIP is a bit too heavy for 8051 arcitecture, but 
our application is very light.

Because some harware conflicts beetween our emulator and the 
development board, the CS8900A driver is not optimal and I can write 
about 150 bytes in 7ms... :-(

We encountered a problem: suddenly, the pcb->snd_queuelen counter in 
the tcp_receive() function (near the comment "Remove segment from the 
unacknowledged list if the incoming ACK acknowlegdes them") become 255. 
I'm quite sure there was one more decrement somewere.
Any hint?

Another small issue: someone told me to test stacks using nmap command 
in Linux. I compiled lwIP for Mandrake 8.1 and kernel 2.4.16, I ran 
nmap and lwIP crash. 

Thanks in advance,


Andrea Olivotto
