Our team is porting OpenBSD PF filter to OS X and the progress so far is good. However we're battling with lots of 'hidden' symbols we need access to. Yes we know this is kernel tied stuff, but the project is supposed to be kernel-tied as closely as possible, so this is OK. We need access to some functions like in_pcblookup* funcs and some primitive ones like _boottime_sec(). The question is simple - we can't link against these functions like _boottime_sec() because they are not exported from Kernel and kextload complains. Can you suggest me the way to workaround this - I just always can't copy-paste parts of the kernel (like I do now!) to implement some funcs. Yes, I understand this is hack, but for now we need a prototype to show to the customer - if it will be successfull I hope they will try to push Apple to help us, but without workaround my hands are tight. Let's start with simple - very simple func _boottime_sec() - it's not exported - how can I still link with it? This email sent to site_archiver@lists.apple.com
