The fstab.extra merge prepends the existing credential via
asprintf("%.*s", (int) existing->size, …). MachineCredential.size is
size_t, so for a credential >INT_MAX the (int) cast yields a negative
precision, which C treats as omitted — turning %.*s into an unbounded
read past the allocation. Reject such a credential up front with EFBIG;
for all realistic sizes the merge is unchanged.
