Attribute failed policy validation

Attribute failed policy validation

[Marco Berizzi]

Hi Folks,

I'm getting this message after the upgrade from linux 4.18 
to 4.19

root@Calimero:~# tc qdisc add dev eth0 root handle 1:0 hfsc default 1
Error: Attribute failed policy validation.

root@Calimero:~# lsmod  |  grep hfsc
sch_hfsc               24576  0

root@Calimero:~# tc -V
tc utility, iproute2-ss181023

Am I doing anything wrong?

caused by:
commit 8b4c3cdd9dd8290343ce959a132d3b334062c5b9
net: sched: Add policy validation for tc attributes

Looks like TCA_OPTIONS is NLA_BINARY in hfsc case, so
we can't enforce NLA_NESTED :-(

Yep. I'll send a fix.
