Hi. Currently I'm writing a kernel module using MAC Framework to control binding to local IP addresses (kind of mac_portacl variation) and I need some advice. I want to be able to write rules for module through sysctl (rule will contain IP addresses in human-readable format, e.g. "uid:1002:192.168.2.3") and I'm wondering how to translate addresses to network byte order without inet_* functions. Well, they look like they're available to use in kernel (using <netinet/in.h>) but it's no able to compile module with inet_* functions using typical Makefile (this one with ".include <bsd.kmod.mk>" line) - it just produces warnings, and all warnings are treated as errors in this case. So, possible solutions are: just add custom CFLAGS without "-Werror" to Makefile (but it's quite ugly though) or write an userspace application that will write an addresses in NBO to sysctl (but now sysctl won't be easy to read and modify by hand). What do you think? Thanks in advance for any useful hints. -- SIGSTOP
