Hi,
As others have noted before me, there is some bitrot in the
register_binfmt() function in fs/exec.c. Does anyone know who the
current maintainer of this code is?
In case the maintainer is reading this, the code in question is this:
int register_binfmt(struct linux_binfmt * fmt)
{
struct linux_binfmt ** tmp = &formats;
if (!fmt)
return -EINVAL;
if (fmt->next)
return -EBUSY;
write_lock(&binfmt_lock);
while (*tmp) {
if (fmt == *tmp) {
write_unlock(&binfmt_lock);
return -EBUSY;
}
tmp = &(*tmp)->next;
}
fmt->next = formats;
formats = fmt;
write_unlock(&binfmt_lock);
return 0;
}
The tmp pointer here is declared as a struct linux_binfmt ** pointer
but a linux_binfmt * would have sufficed as *tmp is never assigned to.
Regards,
Robin Boerdijk
