FAIRQ traffic shaping setup results in pfctl segmentation fault

[tschan]

Hi there,

yesterday I tried to switch my PRIQ traffic shaping setup over to FAIRQ. It seemed to be working at least until my DSL connection was disconnected and reestablished. After that outbound NAT broke completely.

After a lot of investigating I realized that pfctl was crashing when trying to load the automatically generated ruleset.

[2.5.2-RELEASE][admin@pfsense.homenet]/root: pfctl -f /tmp/rules.debug
Segmentation fault (core dumped)

I tracked the offending rules down to this:

 altq on pppoe2 fairq bandwidth 100Mb queue {  qACK,  qDefault,  qGames,  qOthersHigh,  qOthersLow  }
queue qACK on pppoe2 priority 6 fairq (  codel  , ecn  )
queue qDefault on pppoe2 priority 3 fairq (  codel  , ecn  , default  )
queue qGames on pppoe2 priority 5 fairq (  codel  , ecn  )
queue qOthersHigh on pppoe2 priority 4 fairq (  codel  , ecn  )
queue qOthersLow on pppoe2 priority 2 fairq (  codel  , ecn  )

As soon as this was removed (or changed from fairq to priq) it was no longer crashing.

This is my queue setup in the GUI:

Did I hit a bug in pfSense or am I doing something wrong?

@tschan This sounds like bug #11550, which is marked as closed but doesn't appear to be.
