how to add new crypto algorithm inside the kernel

S

solomonml

Hi all,

I am using FreeBSD 7.2. I am trying to add one new encryption algorithm to the crypto library of IPsec. I added the .h and .c files of my new algorithm to opencrypto directory. I also modified the xform.h and xform.c of opencrypto to suite my needs. Finally I buildt the kernel.

My .c file is not compiled. I thought every .c file inside opencrypto will be compiled by default. But, this is not the case and there are undefined reference errors. I tried to see the makefile in /sys/ directory but I cant figure it out.

Please tell me where can I add some lines so that my .c file will be compiled and linked properly.

Thanx in advance
Solomon
 
Hmm, if I'm not wrong crypto stuff is built as module so you will need to modify /sys/modules/* stuff.

For building inside kernel, look into /sys/conf/files.*
 
Thanks richardpl.

I modified the /sys/conf/ files and the build and installation process completed successfully. But, when I try to add some IPsec security associations manually, there is "invalid argument" error. May be it's the reason since I didn't modify /sys/modules/*. I will try to modify and I will post my findings soon.
