Netfilter Users,
I am trying to prioritize traffic from specific IP addresses by using an
ingress filter to set the TOS filed with a pedit action.
In my simple test, I try to set the TOS to 15.
The commands I use are as follows...
sudo tc qdisc add dev wlan0 handle ffff: ingress
sudo tc filter add dev wlan0 protocol ip parent ffff: u32 match ip src
10.0.1.99/32 action pedit ex munge ip dsfield set $((15 << 2)) retain
0xfc action pass
This results in all traffic from the IP being dropped.
I deleted the ingress qdisc and re-added it then added a filter with
just the pass action.
The packets go through.
sudo tc filter add dev wlan0 protocol ip parent ffff: u32 match ip src
10.0.1.99/32 action pass
pi@GW-13:~ $ tc -p -s -d filter show dev wlan0 parent ffff:
filter protocol ip pref 49152 u32 chain 0
filter protocol ip pref 49152 u32 chain 0 fh 800: ht divisor 1
filter protocol ip pref 49152 u32 chain 0 fh 800::800 order 2048 key ht
800 bkt 0 terminal flowid ??? not_in_hw
match IP src 10.0.1.99/32
action order 1: gact action pass
random type none pass val 0
index 1 ref 1 bind 1 installed 6 sec firstused 6 sec
Action statistics:
Sent 2710836 bytes 1917 pkt (dropped 0, overlimits 0 requeues 0)
backlog 0b 0p requeues 0
This seems to indicate the problem is with the pedit action.
Or am I missing something?
hanks in advance,
Keith
