• d32ae76f2   sch_qfq: accurate wsum handling ... Browse Code »

  We can underestimate q->wsum in case of "tc class replace ... qfq"
  and/or qdisc_create_dflt() error.

  wsum is not really used in fast path, only at qfq qdisc/class setup,
  to catch user error.

• 6bafcac32   sch_qfq: fix overflow in qfq_update_start() ... Browse Code »

  grp->slot_shift is between 22 and 41, so using 32bit wide variables is
  probably a typo.

  This could explain QFQ hangs Dave reported to me, after 2^23 packets ?

  (23 = 64 - 41)

• 0545a3037   pkt_sched: QFQ - quick fair queue scheduler ... Browse Code »

  This is an implementation of the Quick Fair Queue scheduler developed
  by Fabio Checconi. The same algorithm is already implemented in ipfw
  in FreeBSD. Fabio had an earlier version developed on Linux, I just
  cleaned it up. Thanks to Eric Dumazet for testing this under load.
