How do you treat differences in ABI ?
Dis-allow loading of module with different value of ABI ? Or were you
planning that module itself adapts to different versions of GRUB 2 ABI's?
The module itself could:
GRUB_MOD_INIT(foo)
{
if (grub_abi != GRUB_ABI)
{
grub_printf ("abi mismatch!\n");
return;
}
/* register our commands/terminals/disks/whatever */
}
Alternative: Export a symbol describing the ABI version in kernel
("grub_abi_3_14"). Access this symbol in each module (this can be hidden
in GRUB_MOD_INIT).
Then loading a module with wrong ABI version fails due to undefined symbol.
