Package: src:linux Version: 3.16.7-2 Severity: normal Dear Maintainer,
the 3.16 series seems to have issues with displaying throughput rates for at least HTB queues. Given this simple egress HTTP shaping setup: /sbin/tc qdisc add dev eth0 root handle 1: htb default 30 /sbin/tc class add dev eth0 parent 1: classid 1:1 htb rate 1000mbit burst 15k /sbin/tc class add dev eth0 parent 1:1 classid 1:10 htb rate 250mbit burst 15k /sbin/tc filter add dev eth0 protocol ip parent 1: prio 1 u32 match ip sport 80 0xffff flowid 1:10 when trying to show statistics for the queues I get: # tc -s class show dev eth0 class htb 1:10 parent 1:1 prio 0 rate 250Mbit ceil 250Mbit burst 15312b cburst 1562b Sent 4772823221 bytes 3243231 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 lended: 1549924 borrowed: 0 giants: 0 tokens: 6286 ctokens: -589 class htb 1:1 root rate 1Gbit ceil 1Gbit burst 15125b cburst 1375b Sent 4772823221 bytes 3243231 pkt (dropped 0, overlimits 0 requeues 0) rate 0bit 0pps backlog 0b 0p requeues 0 lended: 0 borrowed: 0 giants: 0 tokens: 1641 ctokens: -78 The rate and pps counters are always stuck at 0 despite ample amounts of traffic moving through that queue.
