From 4ef8d2e014e377895e55ad1bd2e5eb2cef092e66 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 17 Jul 2014 12:02:06 +0000 Subject: [PATCH] qos-scripts: fix ingress packet marking with ifb Split connection mark into two parts: The lower nibble contains the confirmed conntrack mark which is not generated by default/reclassify rules. The upper nibble contains the current value specified by default/reclassify rules. For egress, the default/reclassify value is preferred For ingress, the connection mark is preferred Signed-off-by: Felix Fietkau SVN-Revision: 41682 --- .../qos-scripts/files/usr/lib/qos/generate.sh | 23 +++++++++++-------- .../qos-scripts/files/usr/lib/qos/tcrules.awk | 17 +++++++++++--- 2 files changed, 27 insertions(+), 13 deletions(-) diff --git a/package/network/config/qos-scripts/files/usr/lib/qos/generate.sh b/package/network/config/qos-scripts/files/usr/lib/qos/generate.sh index 07ec34f51c..7f2376389d 100755 --- a/package/network/config/qos-scripts/files/usr/lib/qos/generate.sh +++ b/package/network/config/qos-scripts/files/usr/lib/qos/generate.sh @@ -53,8 +53,8 @@ parse_matching_rule() { done config_get type "$section" TYPE case "$type" in - classify) unset pkt; append "$var" "-m mark --mark 0/0xff";; - default) pkt=1; append "$var" "-m mark --mark 0/0xff";; + classify) unset pkt; append "$var" "-m mark --mark 0/0x0f";; + default) pkt=1; append "$var" "-m mark --mark 0/0xf0";; reclassify) pkt=1;; esac append "$var" "${proto:+-p $proto}" @@ -165,8 +165,8 @@ parse_matching_rule() { config_get class "${value##!}" classnr [ -z "$class" ] && continue; case "$value" in - !*) append "$var" "-m mark ! --mark $class/0xff";; - *) append "$var" "-m mark --mark $class/0xff";; + !*) append "$var" "-m mark ! --mark $class/0x0f";; + *) append "$var" "-m mark --mark $class/0x0f";; esac ;; 1:TOS) @@ -268,12 +268,13 @@ cls_var() { } tcrules() { - dir=/usr/lib/qos - [ -e $dir/tcrules.awk ] || dir=. + _dir=/usr/lib/qos + [ -e $_dir/tcrules.awk ] || _dir=. echo "$cstr" | awk \ -v device="$dev" \ -v linespeed="$rate" \ - -f $dir/tcrules.awk + -v direction="$dir" \ + -f $_dir/tcrules.awk } start_interface() { @@ -389,6 +390,7 @@ add_rules() { unset iptrule } + target=$(($target | ($target << 4))) parse_matching_rule iptrule "$rule" "$options" "$prefix" "-j MARK --set-mark $target/0xff" append "$var" "$iptrule" "$N" done @@ -407,7 +409,7 @@ start_cg() { config_get maxsize "$class" maxsize [ -z "$maxsize" -o -z "$mark" ] || { add_insmod ipt_length - append pktrules "iptables -t mangle -A qos_${cg} -m mark --mark $mark/0xff -m length --length $maxsize: -j MARK --set-mark 0/0xff" "$N" + append pktrules "iptables -t mangle -A qos_${cg} -m mark --mark $mark/0x0f -m length --length $maxsize: -j MARK --set-mark 0/0xff" "$N" } done add_rules pktrules "$rules" "iptables -t mangle -A qos_${cg}" @@ -427,9 +429,10 @@ $INSMOD iptables -t mangle -N qos_${cg} >&- 2>&- iptables -t mangle -N qos_${cg}_ct >&- 2>&- ${iptrules:+${iptrules}${N}iptables -t mangle -A qos_${cg}_ct -j CONNMARK --save-mark --mask 0xff} -iptables -t mangle -A qos_${cg} -j CONNMARK --restore-mark --mask 0xff -iptables -t mangle -A qos_${cg} -m mark --mark 0/0xff -j qos_${cg}_ct +iptables -t mangle -A qos_${cg} -j CONNMARK --restore-mark --mask 0x0f +iptables -t mangle -A qos_${cg} -m mark --mark 0/0x0f -j qos_${cg}_ct $pktrules +${iptrules:+${iptrules}${N}iptables -t mangle -A qos_${cg} -j CONNMARK --save-mark --mask 0xf0} $up$N${down:+${down}$N} EOF unset INSMOD diff --git a/package/network/config/qos-scripts/files/usr/lib/qos/tcrules.awk b/package/network/config/qos-scripts/files/usr/lib/qos/tcrules.awk index 2a8871495e..8f8eefd938 100644 --- a/package/network/config/qos-scripts/files/usr/lib/qos/tcrules.awk +++ b/package/network/config/qos-scripts/files/usr/lib/qos/tcrules.awk @@ -32,7 +32,7 @@ END { sum_rtprio += prio[i] } } - + # allocation of m1 in rt classes: # sum(d * m1) must not exceed dmax * (linespeed - allocated) dmax = 0 @@ -46,7 +46,7 @@ END { if (d[i] > dmax) dmax = d[i] } } - } + } ds_avail = dmax * (linespeed - allocated) for (i = 1; i <= n; i++) { @@ -84,7 +84,18 @@ END { # filter rule for (i = 1; i <= n; i++) { - print "tc filter add dev "device" parent 1: prio "class[i]" protocol ip handle "class[i]"/0xff fw flowid 1:"class[i] "0" + filter_cmd = "tc filter add dev "device" parent 1: prio %d protocol ip handle %s fw flowid 1:%d0\n"; + if (direction == "up") { + filter_1 = sprintf("0x%x0/0xf0", class[i]) + filter_2 = sprintf("0x0%x/0x0f", class[i]) + } else { + filter_1 = sprintf("0x0%x/0x0f", class[i]) + filter_2 = sprintf("0x%x0/0xf0", class[i]) + } + + printf filter_cmd, class[i] * 2, filter_1, class[i] + printf filter_cmd, class[i] * 2 + 1, filter_2, class[i] + filterc=1 if (filter[i] != "") { print " tc filter add dev "device" parent "class[i]"00: handle "filterc"0 "filter[i] -- 2.30.2
