 |
|
I recently started working on tweaking some networking settings on my system to try to get better responsiveness. I got it all working fine with a script in /etc/local.d, but I'd really like to get it set up so that they get applied by udev rules since I would like the settings applied to any USB networking adapters and virtual network devices I set up on this system after boot. I'm using eudev-3.2 with the old style interface naming. The udev rules I'm using (in /etc/udev/rules.d/99-x-local.rules) are:
| Code: |
KERNEL=="wlan*", SUBSYSTEM=="net", ACTION=="add", RUN(program)+="/usr/local/sbin/tc-setup.sh %E{INTERFACE}"
KERNEL=="eth*", SUBSYSTEM=="net", ACTION=="add", RUN(program)+="/usr/local/sbin/tc-setup.sh %E{INTERFACE}"
KERNEL=="tun*", SUBSYSTEM=="net", ACTION=="add", RUN(program)+="/usr/local/sbin/tc-setup.sh %E{INTERFACE}"
|
and /usr/local/sbin/tc-setup.sh contains:
| Code: |
#!/bin/bash
info=`/sbin/tc qdisc show dev $1 2>&1`
root=`grep root <<< ${info}`
if ( echo ${root} | grep -q pfifo_fast ) ; then
/sbin/tc qdisc replace dev $1 handle 1 root prio
/sbin/tc qdisc add dev $1 handle 11 parent 1:1 sfq limit 100 perturb 5
/sbin/tc qdisc add dev $1 handle 12 parent 1:2 sfq limit 500 perturb 10
/sbin/tc qdisc add dev $1 handle 13 parent 1:3 sfq limit 1000 perturb 15
elif ( echo ${root} | grep -q mq ) ; then
queues=`grep -v mq <<< ${info} | wc -l`
for i in `seq $queues` ; do
/sbin/tc qdisc replace dev $1 handle ${i} parent :${i} prio
/sbin/tc qdisc add dev $1 handle ${i}1 parent ${i}:1 sfq limit 100 perturb 5
/sbin/tc qdisc add dev $1 handle ${i}2 parent ${i}:2 sfq limit 500 perturb 10
/sbin/tc qdisc add dev $1 handle ${i}3 parent ${i}:3 sfq limit 1000 perturb 15
done

This runs correctly for tunX interfaces, but doesn't run for ethX or wlanX interfaces. It works find when invoked manually for any interface.
Output from `udevadm test --action=add /sys/class/net/eth0`:

indicates that /usr/local/sbin/tc-setup.sh should be getting run when eth0 gets processed, but it isn't.
At this point, I've tried just about everything I can think of with the rules and script, and can't figure this out, so I'm hoping someone else might have some insight into why this isn't working. |
