I thought we did handle source-address policy routing for PMTU
messages at least.  I just checked ip_rt_frag_needed and it does

		if (rth->fl.fl4_dst != daddr ||
		    rth->fl.fl4_src != skeys[i] ||
		    rth->rt_dst != daddr ||
		    rth->rt_src != iph->saddr ||
		    rth->fl.oif != ikeys[k] ||
		    rth->fl.iif != 0 ||
		    dst_metric_locked(&rth->u.dst, RTAX_MTU) ||
		    !net_eq(dev_net(rth->u.dst.dev), net) ||
		    rt_is_expired(rth))
			continue;

Cheers,
