It is designed to restore DSCPs -stored in conntrack marks - -The feature is intended for use and has been found useful for restoring -ingress classifications based on egress classifications across links -that bleach or otherwise change DSCP, typically home ISP Internet links. -Restoring DSCP on ingress on the WAN link allows qdiscs such as CAKE to -shape inbound packets according to policies that are easier to implement -on egress. - -Ingress classification is traditionally a challenging task since -iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT -lookups, hence are unable to see internal IPv4 addresses as used on the -typical home masquerading gateway. - -ctinfo understands the following parameters: - -dscp mask[/statemask] - -mask - a 32 bit mask of at least 6 contiguous bits where conndscp will -place the DSCP in conntrack mark. The DSCP is left-shifted by the -number of unset lower bits of the mask before storing into the mark -field. - -statemask - a 32 bit mask of (usually) 1 bit length, outside the area -specified by mask. This represents a conditional operation flag the -DSCP is only restored if the flag is set. This is useful to implement a -'one shot' iptables based classification where the 'complicated' -iptables rules are only run once to classify the connection on initial -(egress) packet and subsequent packets are all marked/restored with the -same DSCP. A mask of zero disables the conditional behaviour. - -optional parameters: - -zone - conntrack zone - -control - action related control (reclassify | pipe | drop | continue | -ok | goto chain <CHAIN_INDEX> - -Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> ---- - include/net/tc_act/tc_ctinfo.h | 28 ++ - include/uapi/linux/pkt_cls.h | 3 +- - include/uapi/linux/tc_act/tc_ctinfo.h | 34 +++ - net/sched/Kconfig | 13 + - net/sched/Makefile | 1 + - net/sched/act_ctinfo.c | 394 ++++++++++++++++++++++++++ - 6 files changed, 472 insertions(+), 1 deletion(-) - create mode 100644 include/net/tc_act/tc_ctinfo.h - create mode 100644 include/uapi/linux/tc_act/tc_ctinfo.h - create mode 100644 net/sched/act_ctinfo.c - -diff --git a/include/net/tc_act/tc_ctinfo.h b/include/net/tc_act/tc_ctinfo.h -new file mode 100644 -index 000000000000..d6a688571672 ---- /dev/null -+++ b/include/net/tc_act/tc_ctinfo.h -@@ -0,0 +1,28 @@ -+/* SPDX-License-Identifier: GPL-2.0 */ -+#ifndef __NET_TC_CTINFO_H -+#define __NET_TC_CTINFO_H -+ -+#include <net/act_api.h> -+ -+struct tcf_ctinfo_params { -+ struct rcu_head rcu;

This represents a conditional operation flag -whereby the DSCP is only restored if the flag is set. This is useful to -implement a 'one shot' iptables based classification where the -'complicated' iptables rules are only run once to classify the -connection on initial (egress) packet and subsequent packets are all -marked/restored with the same DSCP. A mask of zero disables the -conditional behaviour ie. the conntrack mark DSCP bits are always -restored to the ip diffserv field (assuming the conntrack entry is found -& the skb is an ipv4/ipv6 type) - -optional parameters: - -zone - conntrack zone - -control - action related control (reclassify | pipe | drop | continue | -ok | goto chain <CHAIN_INDEX>) - -e.g. dscp 0xfc000000/0x01000000 - -|----0xFC----conntrack mark----000000---| -| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0| -| DSCP | unused | flag |unused | -|-----------------------0x01---000000---| - | | - | | - ---| Conditional flag - v only restore if set -|-ip diffserv-| -| 6 bits | -|-------------| - -Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> ---- - include/net/tc_act/tc_ctinfo.h | 28 ++ - include/uapi/linux/pkt_cls.h | 3 +- - include/uapi/linux/tc_act/tc_ctinfo.h | 34 ++ - net/sched/Kconfig | 17 + - net/sched/Makefile | 1 + - net/sched/act_ctinfo.c | 395 ++++++++++++++++++++++ - tools/testing/selftests/tc-testing/config | 1 + - 7 files changed, 478 insertions(+), 1 deletion(-) - create mode 100644 include/net/tc_act/tc_ctinfo.h - create mode 100644 include/uapi/linux/tc_act/tc_ctinfo.h - create mode 100644 net/sched/act_ctinfo.c - -diff --git a/include/net/tc_act/tc_ctinfo.h b/include/net/tc_act/tc_ctinfo.h -new file mode 100644 -index 000000000000..d6a688571672 ---- /dev/null -+++ b/include/net/tc_act/tc_ctinfo.h -@@ -0,0 +1,28 @@ -+/* SPDX-License-Identifier: GPL-2.0 */ -+#ifndef __NET_TC_CTINFO_H -+#define __NET_TC_CTINFO_H -+ -+#include <net/act_api.h> -+ -+struct tcf_ctinfo_params { -+ struct rcu_head rcu; -+ struct net *net; -+ u32 dscpmask; -+ u32 dscpstatemask; -+ u32 cpmarkmask; -+ u16 zone; -+ u8 mode; -+ u8 dscpmaskshift; -+}; -+ -+struct tcf_ctinfo { -+ struct tc_action common; -+ struct tcf_ctinfo_params __rcu *params; -+ u64 stats_dscp_set; -+ u64 stats_dscp_error; -+ u64 stats_cpmark_set; -+}; -+ -+#define to_ctinfo(a) ((struct tcf_ctinfo *)a) -+ -+#endif /* __NET_TC_CTINFO_H */ -diff --git a/include/uapi/linux/pkt_cls.h b/include/uapi/linux/pkt_cls.h -index be382fb0592d..71e10c5a96a0 100644 ---- a/include/uapi/linux/pkt_cls.h -+++ b/include/uapi/linux/pkt_cls.h -@@ -68,7 +68,8 @@ enum { - TCA_ID_UNSPEC=0, - TCA_ID_POLICE=1, - /* other actions go here */ -- __TCA_ID_MAX=255 -+ TCA_ID_CTINFO, -+ __TCA_ID_MAX = 255 - }; - - #define TCA_ID_MAX __TCA_ID_MAX -diff --git a/include/uapi/linux/tc_act/tc_ctinfo.h b/include/uapi/linux/tc_act/tc_ctinfo.h -new file mode 100644 -index 000000000000..da803e05a89b ---- /dev/null -+++ b/include/uapi/linux/tc_act/tc_ctinfo.h -@@ -0,0 +1,34 @@ -+/* SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note */ -+#ifndef __UAPI_TC_CTINFO_H -+#define __UAPI_TC_CTINFO_H -+ -+#include <linux/types.h> -+#include <linux/pkt_cls.h> -+ -+struct tc_ctinfo { -+ tc_gen; -+}; -+ -+enum { -+ TCA_CTINFO_UNSPEC, -+ TCA_CTINFO_PAD, -+ TCA_CTINFO_TM, -+ TCA_CTINFO_ACT, -+ TCA_CTINFO_ZONE, -+ TCA_CTINFO_PARMS_DSCP_MASK, -+ TCA_CTINFO_PARMS_DSCP_STATEMASK, -+ TCA_CTINFO_PARMS_CPMARK_MASK, -+ TCA_CTINFO_STATS_DSCP_SET, -+ TCA_CTINFO_STATS_DSCP_ERROR, -+ TCA_CTINFO_STATS_CPMARK_SET, -+ __TCA_CTINFO_MAX -+}; -+ -+#define TCA_CTINFO_MAX (__TCA_CTINFO_MAX - 1) -+ -+enum { -+ CTINFO_MODE_DSCP = BIT(0), -+ CTINFO_MODE_CPMARK = BIT(1) -+}; -+ -+#endif -diff --git a/net/sched/Kconfig b/net/sched/Kconfig -index e95741388311..1d79d5dba6e4 100644 ---- a/net/sched/Kconfig -+++ b/net/sched/Kconfig -@@ -866,6 +866,23 @@ config NET_ACT_CONNMARK - To compile this code as a module, choose M here: the - module will be called act_connmark. - -+config NET_ACT_CTINFO -+ tristate "Netfilter Connection Mark Actions" -+ depends on NET_CLS_ACT && NETFILTER && IP_NF_IPTABLES -+ depends on NF_CONNTRACK && NF_CONNTRACK_MARK -+ help -+ Say Y here to allow transfer of a connmark stored information. -+ Current actions transfer connmark stored DSCP into -+ ipv4/v6 diffserv and/or to transfer connmark to packet -+ mark.
