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.
hmmm... how about this (untested) patch?
