[OOPS] 2.6.8 and ingress scheduling

[lkml]

hello,

the last line (filter add) in the "wondershaper" script does sth. to the
kernel, that lets it panic on receiving network packets.

now, if I could capture the trace, that was great... nothing is on disk,
its also more than fits on the screen, and no scrollback exists.

please cc answers/questions,

regards,

peter



PS: excerpt from wondershaper script:

[...]
tc qdisc add dev $DEV handle ffff: ingress
# filter *everything* to it (0.0.0.0/0), drop everything that's
# coming in too fast:

tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip src \
   0.0.0.0/0 police rate ${DOWNLINK}kbit burst 10k drop flowid :1
