Having a strange problem here with the lsm_sys_security call's return value.
When I use the dummy module, the lsm sycall returns -1.  As a simple example,
I used:

#include <stdio.h>
#include <errno.h>
#include <unistd.h>
#define __NR_lsm 223
#include <asm/unistd.h>

_syscall3(long, lsm, int, id, int, what, void *, data);
int main(int argc, char **argv)
{
	long ret;

	ret = lsm(110,3,0);
	printf("tryme: lsm call returned %ld.\n", ret)
}

and tweaked security.c:sys_security to intercept the return value from the
security_ops->sys_security() call.  The value returned from this call is in
fact -38 as it should be, but the above code reports the returned value was
-1.  Am I missing something obvious?

thanks,

kernel.)
