At present it has two independent modes of operation, +restoration of DSCP into IPv4/v6 diffserv and restoration of conntrack +marks into packet skb marks. + +It understands a number of parameters specific to this action in +additional to the usual action syntax. Each operating mode is +independent of the other so all options are optional, however not +specifying at least one mode is a bit pointless. + +Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE] + [CONTROL] [index <INDEX>] + +DSCP mode + +dscp enables copying of a DSCP stored in the conntrack mark into the +ipv4/v6 diffserv field. The mask is a 32bit field and specifies where +in the conntrack mark the DSCP value is located. It must be 6 +contiguous bits long. eg. 0xfc000000 would restore the DSCP from the +upper 6 bits of the conntrack mark. + +The DSCP copying may be optionally controlled by a statemask. The +statemask is a 32bit field, usually with a single bit set and must not +overlap the dscp mask. The DSCP restore operation will only take place +if the corresponding bit/s in conntrack mark ANDed with the statemask +yield a non zero result. + +eg. dscp 0xfc000000 0x01000000 would retrieve the DSCP from the top 6 +bits, whilst using bit 25 as a flag to do so. Bit 26 is unused in this +example. + +CPMARK mode + +cpmark enables copying of the conntrack mark to the packet skb mark. In +this mode it is completely equivalent to the existing act_connmark +action. Additional functionality is provided by the optional mask +parameter, whereby the stored conntrack mark is logically ANDed with the +cpmark mask before being stored into skb mark. This allows shared usage +of the conntrack mark between applications. + +eg. cpmark 0x00ffffff would restore only the lower 24 bits of the +conntrack mark, thus may be useful in the event that the upper 8 bits +are used by the DSCP function. + +Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE] + [CONTROL] [index <INDEX>] +where : + dscp MASK is the bitmask to restore DSCP + STATEMASK is the bitmask to determine conditional restoring + cpmark MASK mask applied to restored packet mark + ZONE is the conntrack zone + CONTROL := reclassify | pipe | drop | continue | ok | + goto chain <CHAIN_INDEX> + +Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> +Reviewed-by: Toke Høiland-Jørgensen <toke@redhat.com> +--- + include/uapi/linux/pkt_cls.h | 3 +- + include/uapi/linux/tc_act/tc_ctinfo.h | 34 ++++ + man/man8/tc-ctinfo.8 | 170 ++++++++++++++++ + tc/Makefile | 1 + + tc/m_ctinfo.c | 268 ++++++++++++++++++++++++++ + 5 files changed, 475 insertions(+), 1 deletion(-) + create mode 100644 include/uapi/linux/tc_act/tc_ctinfo.h + create mode 100644 man/man8/tc-ctinfo.8 + create mode 100644 tc/m_ctinfo.c + +diff --git a/include/uapi/linux/pkt_cls.h b/include/uapi/linux/pkt_cls.h +index 95d0db2a..a6e7e176 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=27, ++ __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 00000000..da803e05 +--- /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/man/man8/tc-ctinfo.8 b/man/man8/tc-ctinfo.8 +new file mode 100644 +index 00000000..096590d1 +--- /dev/null ++++ b/man/man8/tc-ctinfo.8 +@@ -0,0 +1,170 @@ ++.TH "ctinfo action in tc" 8 "4 Jun 2019" "iproute2" "Linux" ++.SH NAME ++ctinfo \- tc connmark processing action ++.SH SYNOPSIS ++.B tc ... action ctinfo ++[ ++.B dscp ++MASK [STATEMASK] ] [ ++.B cpmark ++[MASK] ] [ ++.B zone ++ZONE ] [ ++.B CONTROL ++] [ ++.B index ++<INDEX> ++] ++ ++.SH DESCRIPTION ++CTINFO (Conntrack Information) is a tc action for retrieving data from ++conntrack marks into various fields. At present it has two independent ++processing modes which may be viewed as sub-functions. ++ ++DSCP mode copies a DSCP stored in conntrack's connmark into the IPv4/v6 diffserv ++field. The copying may conditionally occur based on a flag also stored in the ++connmark. DSCP mode was designed to assist in restoring packet classifications on ++ingress, classifications which may then be used by qdiscs such as CAKE. It may be ++used in any circumstance where ingress classification needs to be maintained across ++links that otherwise bleach or remap according to their own policies. ++ ++CPMARK (copymark) mode copies the conntrack connmark into the packet's mark field. Without ++additional parameters it is functionally completely equivalent to the existing ++connmark action. An optional mask may be specified to mask which bits of the ++connmark are restored. This may be useful when DSCP and CPMARK modes are combined. ++ ++Simple statistics (tc -s) on DSCP restores and CPMARK copies are maintained where values for ++set indicate a count of packets altered for that mode. DSCP includes an error count ++where the destination packet's diffserv field was unwriteable. ++.SH PARAMETERS ++.SS DSCP mode parameters: ++.IP mask ++A mask of 6 contiguous bits indicating where the DSCP value is located in the 32 bit ++conntrack mark field. A mask must be provided for this mode. mask is a 32 bit ++unsigned value. ++.IP statemask ++A mask of at least 1 bit indicating where a conditional restore flag is located in the ++32 bit conntrack mark field. The statemask bit/s must NOT overlap the mask bits. The ++DSCP will be restored if the conntrack mark logically ANDed with the statemask yields ++a non-zero result. statemask is an optional unsigned 32 bit value. ++.SS CPMARK mode parameters: ++.IP mask ++Store the logically ANDed result of conntrack mark and mask into the packet's mark ++field. Default is 0xffffffff i.e. the whole mark field. mask is an optional unsigned 32 bit ++value ++.SS Overall action parameters: ++.IP zone ++Specify the conntrack zone when doing conntrack lookups for packets. ++zone is a 16bit unsigned decimal value. ++Default is 0. ++.IP CONTROL ++The following keywords allow to control how the tree of qdisc, classes, ++filters and actions is further traversed after this action. ++.RS ++.TP ++.B reclassify ++Restart with the first filter in the current list. ++.TP ++.B pipe ++Continue with the next action attached to the same filter. ++.TP ++.B drop ++Drop the packet. ++.TP ++.B shot ++synonym for ++.B drop ++.TP ++.B continue ++Continue classification with the next filter in line. ++.TP ++.B pass ++Finish classification process and return to calling qdisc for further packet ++processing. This is the default. ++.RE ++.IP index ++Specify an index for this action in order to being able to identify it in later ++commands. index is a 32bit unsigned decimal value. ++.SH EXAMPLES ++Example showing conditional restoration of DSCP on ingress via an IFB ++.RS ++.EX ++ ++#Set up the IFB interface ++.br ++tc qdisc add dev ifb4eth0 handle ffff: ingress ++ ++#Put CAKE qdisc on it ++.br ++tc qdisc add dev ifb4eth0 root cake bandwidth 40mbit ++ ++#Set interface UP ++.br ++ip link set dev ifb4eth0 up ++ ++#Add 2 actions, ctinfo to restore dscp & mirred to redirect the packets to IFB ++.br ++tc filter add dev eth0 parent ffff: protocol all prio 10 u32 \\ ++ match u32 0 0 flowid 1:1 action \\ ++ ctinfo dscp 0xfc000000 0x01000000 \\ ++ mirred egress redirect dev ifb4eth0 ++ ++tc -s qdisc show dev eth0 ingress ++ ++ filter parent ffff: protocol all pref 10 u32 chain 0 ++ filter parent ffff: protocol all pref 10 u32 chain 0 fh 800: ht divisor 1 ++ filter parent ffff: protocol all pref 10 u32 chain 0 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:1 not_in_hw ++ match 00000000/00000000 at 0 ++ action order 1: ctinfo zone 0 pipe ++ index 2 ref 1 bind 1 dscp 0xfc000000 0x01000000 installed 72 sec used 0 sec DSCP set 1333 error 0 CPMARK set 0 ++ Action statistics: ++ Sent 658484 bytes 1833 pkt (dropped 0, overlimits 0 requeues 0) ++ backlog 0b 0p requeues 0 ++ ++ action order 2: mirred (Egress Redirect to device ifb4eth0) stolen ++ index 1 ref 1 bind 1 installed 72 sec used 0 sec ++ Action statistics: ++ Sent 658484 bytes 1833 pkt (dropped 0, overlimits 0 requeues 0) ++ backlog 0b 0p requeues 0 ++.EE ++.RE ++ ++Example showing conditional restoration of DSCP on egress ++ ++This may appear nonsensical since iptables marking of egress packets is easy ++to achieve, however the iptables flow classification rules may be extensive ++and so some sort of set once and forget may be useful especially on cpu ++constrained devices. ++.RS ++.EX ++ ++# Send unmarked connections to a marking chain which needs to store a DSCP ++and set statemask bit in the connmark ++.br ++iptables -t mangle -A POSTROUTING -o eth0 -m connmark \\ ++ --mark 0x00000000/0x01000000 -g CLASS_MARKING_CHAIN ++ ++# Apply marked DSCP to the packets ++.br ++tc filter add dev eth0 protocol all prio 10 u32 \\ ++ match u32 0 0 flowid 1:1 action \\ ++ ctinfo dscp 0xfc000000 0x01000000 ++ ++tc -s filter show dev eth0 ++ filter parent 800e: protocol all pref 10 u32 chain 0 ++ filter parent 800e: protocol all pref 10 u32 chain 0 fh 800: ht divisor 1 ++ filter parent 800e: protocol all pref 10 u32 chain 0 fh 800::800 order 2048 key ht 800 bkt 0 flowid 1:1 not_in_hw ++ match 00000000/00000000 at 0 ++ action order 1: ctinfo zone 0 pipe ++ index 1 ref 1 bind 1 dscp 0xfc000000 0x01000000 installed 7414 sec used 0 sec DSCP set 53404 error 0 CPMARK set 0 ++ Action statistics: ++ Sent 32890260 bytes 120441 pkt (dropped 0, overlimits 0 requeues 0) ++ backlog 0b 0p requeues 0 ++.br ++.SH SEE ALSO ++.BR tc (8), ++.BR tc-cake (8) ++.BR tc-connmark (8) ++.BR tc-mirred (8) ++.SH AUTHORS ++ctinfo was written by Kevin Darbyshire-Bryant. +diff --git a/tc/Makefile b/tc/Makefile +index 2edaf2c8..ec93a9a1 100644 +--- a/tc/Makefile ++++ b/tc/Makefile +@@ -48,6 +48,7 @@ TCMODULES += m_csum.o + TCMODULES += m_simple.o + TCMODULES += m_vlan.o + TCMODULES += m_connmark.o ++TCMODULES += m_ctinfo.o + TCMODULES += m_bpf.o + TCMODULES += m_tunnel_key.o + TCMODULES += m_sample.o +diff --git a/tc/m_ctinfo.c b/tc/m_ctinfo.c +new file mode 100644 +index 00000000..5e451f87 +--- /dev/null ++++ b/tc/m_ctinfo.c +@@ -0,0 +1,268 @@ ++/* SPDX-License-Identifier: GPL-2.0 */ ++/* ++ * m_ctinfo.c netfilter ctinfo mark action ++ * ++ * Copyright (c) 2019 Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk> ++ */ ++ ++#include <stdio.h> ++#include <stdlib.h> ++#include <unistd.h> ++#include <string.h> ++#include "utils.h" ++#include "tc_util.h" ++#include <linux/tc_act/tc_ctinfo.h> ++ ++static void ++explain(void) ++{ ++ fprintf(stderr, ++ "Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE] [CONTROL] [index <INDEX>]\n" ++ "where :\n" ++ "\tdscp MASK bitmask location of stored DSCP\n" ++ "\t STATEMASK bitmask to determine conditional restoring\n" ++ "\tcpmark MASK mask applied to mark on restoration\n" ++ "\tZONE is the conntrack zone\n" ++ "\tCONTROL := reclassify | pipe | drop | continue | ok |\n" ++ "\t goto chain <CHAIN_INDEX>\n");
