  "message": "[PKT_SCHED] RED: Fix overflow in calculation of queue average\n\nOverflow can occur very easily with 32 bits, e.g., with 1 second\nus_idle is approx. 2^20, which leaves only 11-Wlog bits for queue\nlength. Since the EWMA exponent is typically around 9, queue\nlengths larger than 2^2 cause overflow. Whether the affected\nbranch is taken when us_idle is as high as 1 second, depends on\nScell_log, but with rather reasonable configuration Scell_log is\nlarge enough to cause p-\u003eStab to have zero index, which always\nresults zero shift (typically also few other small indices result\nin zero shift).\n\nSigned-off-by: Ilpo Järvinen \u003cilpo.jarvinen@helsinki.fi\u003e\nSigned-off-by: David S.
