[iproute2] addattr_* vs. maxlen

[iproute2] addattr_* vs. maxlen

[Thorsten Glaser]

Hi,

(please Cc me, I’m no longer subscribed)

can please someone explain THIS (tc/q_htb.c):

	tail = addattr_nest(n, 1024, TCA_OPTIONS);

	if (rate64 >= (1ULL << 32))
		addattr_l(n, 1124, TCA_HTB_RATE64, &rate64, sizeof(rate64));

	if (ceil64 >= (1ULL << 32))
		addattr_l(n, 1224, TCA_HTB_CEIL64, &ceil64, sizeof(ceil64));

	addattr_l(n, 2024, TCA_HTB_PARMS, &opt, sizeof(opt));
	addattr_l(n, 3024, TCA_HTB_RTAB, rtab, 1024);
	addattr_l(n, 4024, TCA_HTB_CTAB, ctab, 1024);

From the reading of the libnetlink(3) manpage I’d have expected maxlen
to stay constant, and to be defined somehow near n’s allocation?

Thanks in advance,
