I'm a colleague of Lynn's and wanted to put my old C experience to use here,
but have hit a snag. I'm attempting to insert my hook early in iPXE's
execution through __init_fn but it never executes. The debug text strings
don't even appear in the final binary unless I stuff the code into something
else, like 'core/device.c'. Am I missing something in the following code?
/* Relevant includes: */
#include <stdio.h>
#include <errno.h>
#include <ipxe/efi/efi.h>
#include <ipxe/init.h>
/* Skipping the meat of the hook/wrap code */
static void dj1_wrap_init(void) {
printf("DJ1_wrap_init - Called\n");
/* The start/stop logic depends on this value being NULL when we start
*/
dj1_orig_FreePool = NULL;
/* CAUTION: If this is uncommented we enable wrapping for ALL of these
calls! */
dj1_wrap_start();
}
/**
* Prepare for FreePool wrapping - This tells core/init.c to call dj1_wrap_init()
*/
struct init_fn dj1_efi_wrap_init_fn __init_fn ( INIT_EARLY ) = {
.initialise = dj1_wrap_init,
};
