This should allow +ptrace.h to be used alongside libc's sigcontext.h (if any) without +ill effects. + +This should make the situation unambiguous: <asm/sigcontext.h> is +the header to include for the sigframe-specific definitions, while +<asm/ptrace.h> is the header to include for ptrace-specific +definitions. + +To avoid conflicting with existing usage, <asm/sigcontext.h> +remains the canonical way to get the common definitions for +SVE_VQ_MIN, sve_vq_from_vl() etc., both in userspace and in the +kernel: relying on these being defined as a side effect of +including just <asm/ptrace.h> was

It is designed to restore +information contained in firewall conntrack marks to other packet fields +and is typically used on packet ingress paths. At present it has two +independent sub-functions or operating modes, DSCP restoration mode & +skb mark restoration mode. + +The DSCP restore mode: + +This mode copies DSCP values that have been placed in the firewall +conntrack mark back into the IPv4/v6 diffserv fields of relevant +packets. + +The DSCP restoration 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 +but by no means limited to CAKE to shape inbound packets according to +policies that are easier to set & mark 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. Thus marking the connection in some +manner on egress for later restoration of classification on ingress is +easier to implement. + +Parameters related to DSCP restore mode: + +dscpmask - a 32 bit mask of 6 contiguous bits and indicate bits of the +conntrack mark field contain the DSCP value to be restored. + +statemask - a 32 bit mask of (usually) 1 bit length, outside the area +specified by dscpmask. 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) + +e.g. dscpmask 0xfc000000 statemask 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 | +|-------------| + +The skb mark restore mode (cpmark): + +This mode copies the firewall conntrack mark to the skb's mark field. +It is completely the functional equivalent of the existing act_connmark +action with the additional feature of being able to apply a mask to the +restored value. + +Parameters related to skb mark restore mode: + +mask - a 32 bit mask applied to the firewall conntrack mark to mask out +bits unwanted for restoration.

This results in WARNs during network interface bringup and shutdown +when a copper SFP module is connected, as phy_start() and phy_stop() are +called twice in a row for the same phy_device: + + % ip link set up dev eth0 + ------------[ cut here ]------------ + called from state UP + WARNING: CPU: 1 PID: 155 at drivers/net/phy/phy.c:895 phy_start+0x74/0xc0 + Modules linked in: + CPU: 1 PID: 155 Comm: backend Not tainted 5.2.0+ #1 + NIP: c0227bf0 LR: c0227bf0 CTR: c004d224 + REGS: df547720 TRAP: 0700 Not tainted (5.2.0+) + MSR: 00029000 <CE,EE,ME> CR: 24002822 XER: 00000000 + + GPR00: c0227bf0 df5477d8 df5d7080 00000014 df9d2370 df9d5ac4 1f4eb000 00000001 + GPR08: c061fe58 00000000 00000000 df5477d8 0000003c 100c8768 00000000 00000000 + GPR16: df486a00 c046f1c8 c046eea0 00000000 c046e904 c0239604 db68449c 00000000 + GPR24: e9083204 00000000 00000001 db684460 e9083404 00000000 db6dce00 db6dcc00 + NIP [c0227bf0] phy_start+0x74/0xc0 + LR [c0227bf0] phy_start+0x74/0xc0 + Call Trace: + [df5477d8] [c0227bf0] phy_start+0x74/0xc0 (unreliable) + [df5477e8] [c023cad0] startup_gfar+0x398/0x3f4 + [df547828] [c023cf08] gfar_enet_open+0x364/0x374 + [df547898] [c029d870] __dev_open+0xe4/0x140 + [df5478c8] [c029db70] __dev_change_flags+0xf0/0x188 + [df5478f8] [c029dc28] dev_change_flags+0x20/0x54 + [df547918] [c02ae304] do_setlink+0x310/0x818 + [df547a08] [c02b1eb8] __rtnl_newlink+0x384/0x6b0 + [df547c28] [c02b222c] rtnl_newlink+0x48/0x68 + [df547c48] [c02ad7c8] rtnetlink_rcv_msg+0x240/0x27c + [df547c98] [c02cc068] netlink_rcv_skb+0x8c/0xf0 + [df547cd8] [c02cba3c] netlink_unicast+0x114/0x19c + [df547d08] [c02cbd74] netlink_sendmsg+0x2b0/0x2c0 + [df547d58] [c027b668] sock_sendmsg_nosec+0x20/0x40 + [df547d68] [c027d080] ___sys_sendmsg+0x17c/0x1dc + [df547e98] [c027df7c] __sys_sendmsg+0x68/0x84 + [df547ef8] [c027e430] sys_socketcall+0x1a0/0x204 + [df547f38] [c000d1d8] ret_from_syscall+0x0/0x38 + --- interrupt: c01 at 0xfd4e030 + LR = 0xfd4e010 + Instruction dump: + 813f0188 38800000 2b890005 419d0014 3d40c046 5529103a 394aa208 7c8a482e + 3c60c046 3863a1b8 4cc63182 4be009a1 <0fe00000> 48000030 3c60c046 3863a1d0 + ---[ end trace d4c095aeaf6ea998 ]--- + +and + + % ip link set down dev eth0 + ------------[ cut here ]------------ + called from state HALTED + WARNING: CPU: 1 PID: 184 at drivers/net/phy/phy.c:858 phy_stop+0x3c/0x88 + + <...> + + Call Trace: + [df581788] [c0228450] phy_stop+0x3c/0x88 (unreliable) + [df581798] [c022d548] sfp_sm_phy_detach+0x1c/0x44 + [df5817a8] [c022e8cc] sfp_sm_event+0x4b0/0x87c + [df581848] [c022f04c] sfp_upstream_stop+0x34/0x44 + [df581858] [c0225608] phylink_stop+0x7c/0xe4 + [df581868] [c023c57c] stop_gfar+0x7c/0x94 + [df581888] [c023c5b8] gfar_close+0x24/0x94 + [df5818a8] [c0298688] __dev_close_many+0xdc/0xf8 + [df5818c8] [c029db58] __dev_change_flags+0xd8/0x188 + [df5818f8] [c029dc28] dev_change_flags+0x20/0x54 + [df581918] [c02ae304] do_setlink+0x310/0x818 + [df581a08] [c02b1eb8] __rtnl_newlink+0x384/0x6b0 + [df581c28] [c02b222c] rtnl_newlink+0x48/0x68 + [df581c48] [c02ad7c8] rtnetlink_rcv_msg+0x240/0x27c + [df581c98] [c02cc068] netlink_rcv_skb+0x8c/0xf0 + [df581cd8] [c02cba3c] netlink_unicast+0x114/0x19c + [df581d08] [c02cbd74] netlink_sendmsg+0x2b0/0x2c0 + [df581d58] [c027b668] sock_sendmsg_nosec+0x20/0x40 + [df581d68] [c027d080] ___sys_sendmsg+0x17c/0x1dc + [df581e98] [c027df7c] __sys_sendmsg+0x68/0x84 + [df581ef8] [c027e430] sys_socketcall+0x1a0/0x204 + [df581f38] [c000d1d8] ret_from_syscall+0x0/0x38 + + <...> + + ---[ end trace d4c095aeaf6ea999 ]--- + +SFP modules with the 1000Base-X interface are not affected. + +Place explicit calls to phy_start() and phy_stop() before enabling or after +disabling an attached SFP module, where phydev is not yet set (or is +already unset), so they will be made only from the inside of sfp-bus, if +needed. + +Fixes: 217962615662 ("net: phy: warn if phy_start is called from invalid state") +Signed-off-by: Arseny Solokha <asolokha@kb.kras.ru> +Acked-by: Russell King <rmk+kernel@armlinux.org.uk> +Signed-off-by: David S.

In combination with a suitable tc filter action +(act_ctinfo) DSCP values are able to be stored in the mark on egress and +restored on ingress across links that otherwise alter or bleach DSCP. + +This is useful for qdiscs such as CAKE which are able to shape according +to policies based on DSCP. + +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. + +x_tables CONNMARK set-dscpmark target solves the problem of storing the +DSCP to the conntrack mark in a way suitable for the new act_ctinfo tc +action to restore. + +The set-dscpmark option accepts 2 parameters, a 32bit 'dscpmask' and a +32bit 'statemask'. The dscp mask must be 6 contiguous bits and +represents the area where the DSCP will be stored in the connmark. The +state mask is a minimum 1 bit length mask that must not overlap with the +dscpmask. It represents a flag which is set when the DSCP has been +stored in the conntrack mark. 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 state +mask of zero disables the setting of a status bit/s. + +example syntax with a suitably modified iptables user space application: + +iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --set-dscpmark 0xfc000000/0x01000000 + +Would store the DSCP in the top 6 bits of the 32bit mark field, and use +the LSB of the top byte as the 'DSCP has been stored' marker. + +|----0xFC----conntrack mark----000000---| +| Bits 31-26 | bit 25 | bit24 |~~~ Bit 0| +| DSCP | unused | flag |unused | +|-----------------------0x01---000000---| + ^ ^ + | | + ---| Conditional flag + | set this when dscp +|-ip diffserv-| stored in mark +| 6 bits | +|-------------| + +an identically configured tc action to restore looks like: + +tc filter 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: not_in_hw + match 00000000/00000000 at 0 + action order 1: ctinfo zone 0 pipe + index 2 ref 1 bind 1 dscp 0xfc000000/0x1000000 + + action order 2: mirred (Egress Redirect to device ifb4eth0) stolen + index 1 ref 1 bind 1 + +|----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/uapi/linux/netfilter/xt_connmark.h | 10 ++++ + net/netfilter/xt_connmark.c | 55 ++++++++++++++++++---- + 2 files changed, 57 insertions(+), 8 deletions(-) + +--- a/include/uapi/linux/netfilter/xt_connmark.h ++++ b/include/uapi/linux/netfilter/xt_connmark.h +@@ -20,6 +20,11 @@ enum { + };
