network stack problem in sparc64?

[Borja Marcos]

Hello,

I saw this some time ago but always forgot to report it.

I'm running a pair of machines with FreeBSD/sparc64 (various  
versions, one of them is running -STABLE now), and I've seen a  
problem with the network stack.

Looking at buffer and window sizes,

earendil# sysctl net.inet.tcp|fgrep space
net.inet.tcp.sendspace: 0
net.inet.tcp.recvspace: 0

earendil# sysctl net.inet.udp
net.inet.udp.checksum: 1
net.inet.udp.maxdgram: 0
net.inet.udp.recvspace: 0

When I try to modify them, it doesn't work at all. For example,  
trying to run nfcapd/nfsen in a sparc64 box, I get an error for a  
setsockopt() call

earendil# /usr/local/etc/rc.d/nfsen start
Starting nfsenStarting nfcpad: upstream1setsockopt(SO_RCVBUF,200000):  
Invalid argument
Terminated due to errors.
nfcapd exec error: exit: 255, signal: 0, coredump: 0


For x86 machines the values are correctly reported and they work as  
expected.

I have been poking Google for this but I haven't seen any mention of  
this.

Best regards,





Borja.


P.S: The example machine is running
earendil# uname -a
FreeBSD earendil.arnor.es 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #0:
