Hello,

There are couple of patches for modprobe and insmod...

You could see them on the top at:
http://linux-ima.git.sourceforge.net/git/gitweb.cgi?p=linux-ima/module-init-tools.git;a=summary

It first tries to read signature from xattr, then from file...
"modprobe -v" will show 'ima='  parameter with signature.
