Hi Andrew,

You can redirect syscalls to another function with loadable kernel modules.


Some documentation/examples you might want to read first:

/usr/share/examples/kld
http://www.r4k.net/mod/fbsdfun.html
http://packetstormsecurity.org/papers/unix/bsdkern.htm
http://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/driverbasics-
kld.html



With best regards,

Thijs Eilander
