"netstat" uses kvm_read(), etc. to read kernel symbols. However, this doesn't work when the symbols you're looking for are in an KLD module (eg, ng_socket.ko) -- the symbol will not be found. So I added some code/hackery to look for any loaded modules and if on named "ng_socket.ko" was found, try finding the symbol in there. My question is, should kvm_read() and friends be "enhanced" with this ability to find a symbol by searching through the loaded KLD modules? Seems a bit hackish, but then again so is the whole kvm() idea. I'd be willing to add this code if so.. it's not much. Unrelated question: SYSINIT() doesn't work from KLD modules. Is this problem being addressed? -Archie ___________________________________________________________________________ Archie Cobbs * Whistle Communications, Inc. * http://www.whistle.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
