>Description:
 p0f and nmap hang on my Solaris2.8 boxes if they are compiled with the latest 
net/libpcap, 0.8.3.  truss shows they are stuck in "getmsg".  I let p0f run for 
a while and it did eventually see the packets, but not until several minutes 
after they had actually arrived.  Moving back to libpcap-0.7.2 fixes the 
problem.  The release notes at tcpdump.org mention a 64bit fix for gencode.c, 
I'm not sure if that's related or not.

 I haven't noticed this on my NetBSD/i386-current machine.  I don't have a 
NetBSD/sparc64 install to check anymore.
>How-To-Repeat:
Install the latest libpcap and nmap from pkgsrc, then try to nmap a host.
>Fix:
crn-sen:/usr/pkgsrc/net/libpcap #cvs -q update -D 20040927
