Dear Sir/Madam;
A problem is troubling me in ages.
I want to add my encryption algorithm of ESP, an
algorithm like DES, into FreeBSD kernel so as to make
kernel recognize it. I added its definitions in
/usr/src/sys/net/pfkeyv2.h, added specific functions
implementation into /usr/src/sys/netinet6/esp.core.c
and added a new subdirectory in sys/crypto. Afterwards
I rebuild kernel, but system can't recognize my ESP
encryption algorithm when I use PF socket or setkey
command to add a new SA into SAD including my new
encryption.
In a word, please tell me what I should do
step by step if I want to add a new ESP encryption
algorithm that I have already implemented into kernel
so that I can use setkey commmand or sock system call
to add SAs into SAD and the kernel can use fucntions
I
provided to encrypt or decrypt incoming or outgoing IP
packages.
Any your assistance would be greatly appreciated.
Sincerelly yours,
Tang hongbin
