All 32-bit operations are implemented natively by the JIT, +except if the CPU lacks ll/sc instructions. + +Register mapping +================ +All 64-bit eBPF registers are mapped to native 32-bit MIPS register pairs, +and does not use any stack scratch space for register swapping. This means +that all eBPF register data is kept in CPU registers all the time, and +this simplifies the register management a lot. It also reduces the JIT's +pressure on temporary registers since we do not have to move data around. + +Native register pairs are ordered according to CPU endiannes, following +the O32 calling convention for passing 64-bit arguments and return values. +The eBPF return value, arguments and callee-saved registers are mapped to +their native MIPS equivalents. + +Since the 32 highest bits in the eBPF FP (frame pointer) register are +always zero, only one general-purpose register is actually needed for the +mapping. The MIPS fp register is used for this purpose. The high bits are +mapped to MIPS register r0. This saves us one CPU register, which is much +needed for temporaries, while still allowing us to treat the R10 (FP) +register just like any other eBPF register in the JIT. + +The MIPS gp (global pointer) and at (assembler temporary) registers are +used as internal temporary registers for constant blinding. CPU registers +t6-t9 are used internally by the JIT when constructing more complex 64-bit +operations. This is precisely what is needed - two registers to store an +operand value, and two more as scratch registers when performing the +operation. + +The register mapping is shown below. + + R0 - $v1, $v0 return value + R1 - $a1, $a0 argument 1, passed in registers + R2 - $a3, $a2 argument 2, passed in registers + R3 - $t1, $t0 argument 3, passed on stack + R4 - $t3, $t2 argument 4, passed on stack + R5 - $t4, $t3 argument 5, passed on stack + R6 - $s1, $s0 callee-saved + R7 - $s3, $s2 callee-saved + R8 - $s5, $s4 callee-saved + R9 - $s7, $s6 callee-saved + FP - $r0, $fp 32-bit frame pointer + AX - $gp, $at constant-blinding + $t6 - $t9 unallocated, JIT temporaries + +Jump offsets +============ +The JIT tries to map all conditional JMP operations to MIPS conditional +PC-relative branches. The MIPS branch offset field is 18 bits, in bytes, +which is equivalent to the eBPF 16-bit instruction offset. However, since +the JIT may emit more than one CPU instruction per eBPF instruction, the +field width may overflow. If that happens, the JIT converts the long +conditional jump to a short PC-relative branch with the condition +inverted, jumping over a long unconditional absolute jmp (j). + +This conversion will change the instruction offset mapping used for jumps, +and may in turn result in more branch offset overflows. The JIT therefore +dry-runs the translation until no more branches are converted and the +offsets do not change anymore. There is an upper bound on this of course, +and if the JIT hits that limit, the last two iterations are run with all +branches being converted. + +Tail call count +=============== +The current tail call count is stored in the 16-byte area of the caller's +stack frame that is reserved for the callee in the o32 ABI. The value is +initialized in the prologue, and propagated to the tail-callee by skipping +the initialization instructions when emitting the tail call. + +Signed-off-by: Johan Almbladh <johan.almbladh@anyfinetworks.com> +--- + create mode 100644 arch/mips/net/bpf_jit_comp.c + create mode 100644 arch/mips/net/bpf_jit_comp.h + create mode 100644 arch/mips/net/bpf_jit_comp32.c + +--- a/arch/mips/net/Makefile ++++ b/arch/mips/net/Makefile +@@ -2,4 +2,9 @@ + # MIPS networking code + + obj-$(CONFIG_MIPS_CBPF_JIT) += bpf_jit.o bpf_jit_asm.o +-obj-$(CONFIG_MIPS_EBPF_JIT) += ebpf_jit.o ++ ++ifeq ($(CONFIG_32BIT),y) ++ obj-$(CONFIG_MIPS_EBPF_JIT) += bpf_jit_comp.o bpf_jit_comp32.o ++else ++ obj-$(CONFIG_MIPS_EBPF_JIT) += ebpf_jit.o ++endif +--- /dev/null ++++ b/arch/mips/net/bpf_jit_comp.c +@@ -0,0 +1,1020 @@ ++// SPDX-License-Identifier: GPL-2.0-only ++/* ++ * Just-In-Time compiler for eBPF bytecode on MIPS. ++ * Implementation of JIT functions common to 32-bit and 64-bit CPUs. ++ * ++ * Copyright (c) 2021 Anyfi Networks AB. ++ * Author: Johan Almbladh <johan.almbladh@gmail.com> ++ * ++ * Based on code and ideas from ++ * Copyright (c) 2017 Cavium, Inc. ++ * Copyright (c) 2017 Shubham Bansal <illusionist.neo@gmail.com> ++ * Copyright (c) 2011 Mircea Gherzan <mgherzan@gmail.com> ++ */ ++ ++/* ++ * Code overview ++ * ============= ++ * ++ * - bpf_jit_comp.h ++ * Common definitions and utilities. ++ * ++ * - bpf_jit_comp.c ++ * Implementation of JIT top-level logic and exported JIT API functions. ++ * Implementation of internal operations shared by 32-bit and 64-bit code. ++ * JMP and ALU JIT control code, register control code, shared ALU and ++ * JMP/JMP32 JIT operations. ++ * ++ * - bpf_jit_comp32.c ++ * Implementation of functions to JIT prologue, epilogue and a single eBPF ++ * instruction for 32-bit MIPS CPUs.

This table is computed by dry-running the ++ * JIT without actually emitting anything. However, the computed PC-relative ++ * offset may overflow the 18-bit offset field width of the native MIPS ++ * branch instruction.

This makes sense for +block encryption, but given that ChaCha is also often used in the +context of networking, it makes sense to consider arbitrary length +inputs as well. + +For example, WireGuard typically uses 1420 byte packets, and performing +ChaCha encryption involves 5 invocations of chacha_4block_xor_neon() +and 3 invocations of chacha_block_xor_neon(), where the last one also +involves a memcpy() using a buffer on the stack to process the final +chunk of 1420 % 64 == 12 bytes. + +Let's optimize for this case as well, by letting chacha_4block_xor_neon() +deal with any input size between 64 and 256 bytes, using NEON permutation +instructions and overlapping loads and stores. This way, the 140 byte +tail of a 1420 byte input buffer can simply be processed in one go. + +This results in the following performance improvements for 1420 byte +blocks, without significant impact on power-of-2 input sizes.

The ++flowtable infrastructure discovers the topology behind the bridge device. This ++allows the flowtable to define a fastpath bypass between the bridge ports ++(represented as eth1 and eth2 in the example figure below) and the gateway ++device (represented as eth0) in your switch/router. ++ ++:: ++ fastpath bypass ++ .-------------------------. ++ / \ ++ | IP forwarding | ++ | / \ \/ ++ | br0 eth0 ..... eth0 ++ . / \ *host B* ++ -> eth1 eth2 ++ . *switch/router* ++ . ++ . ++ eth0 ++ *host A* ++ ++The flowtable infrastructure also supports for bridge VLAN filtering actions ++such as PVID and untagged. You can also stack a classic VLAN device on top of ++your bridge port. ++ ++If you would like that your flowtable defines a fastpath between your bridge ++ports and your IP forwarding path, you have to add your bridge ports (as ++represented by the real netdevice) to your flowtable definition. ++ ++Counters ++-------- ++ ++The flowtable can synchronize packet and byte counters with the existing ++connection tracking entry by specifying the counter statement in your flowtable ++definition, e.g. ++ ++:: ++ table inet x { ++ flowtable f { ++ hook ingress priority 0; devices = { eth0, eth1 }; ++ counter ++ } ++ ... ++ } ++ ++Counter support is available since Linux kernel 5.7. ++ ++Hardware offload ++---------------- ++ ++If your network device provides hardware offload support, you can turn it on by ++means of the 'offload' flag in your flowtable definition, e.g. ++ ++:: ++ table inet x { ++ flowtable f { ++ hook ingress priority 0; devices = { eth0, eth1 }; ++ flags offload; ++ } ++ ... ++ } ++ ++There is a workqueue that adds the flows to the hardware.

So, since bridging between eth0 (where Station B is +attached) and swp0 (where Station A is attached) is done in software, +the switchdev hardware will never learn the source address of Station B. +So the traffic towards that destination will be treated as unknown, i.e. +flooded. + +This is where the bridge notifications come in handy. When br0 on the +DUT sees frames with Station B's MAC address on eth0, the switchdev +driver gets these notifications and can install a rule to send frames +towards Station B's address that are incoming from swp0, swp1, swp2, +only towards the control interface.

It moves the entry in the software bridge +to swp1 and emits an addition notification towards that. + +As far as the switchdev driver is concerned, all that it needs to ensure +is that traffic between Station A and Station B is not forever broken. +If it does nothing, then the stale rule to send frames for Station B +towards the control interface remains in place. But Station B is no +longer reachable via the control interface, but via a port that can +offload the bridge port learning attribute. It's just that the port is +prevented from learning this address, since the rule overrides FDB +updates. So the rule needs to go. The question is via what mechanism. + +It sure would be possible for this switchdev driver to keep track of all +addresses which are sent to the control interface, and then also listen +for bridge notifier events on its own ports, searching for the ones that +have a MAC address which was previously sent to the control interface. +But this is cumbersome and inefficient. Instead, with one small change, +the bridge could notify of the address deletion from the old port, in a +symmetrical manner with how it did for the insertion. Then the switchdev +driver would not be required to monitor learn/forget events for its own +ports. It could just delete the rule towards the control interface upon +bridge entry migration. This would make hardware address learning be +possible again. Then it would take a few more packets until the hardware +and software FDB would be in sync again. + +Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> +Acked-by: Nikolay Aleksandrov <nikolay@nvidia.com> +Reviewed-by: Ido Schimmel <idosch@nvidia.com> +Reviewed-by: Andrew Lunn <andrew@lunn.ch> +Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> +Signed-off-by: Jakub Kicinski <kuba@kernel.org> +--- + net/bridge/br_fdb.c | 1 + + 1 file changed, 1 insertion(+) + +--- a/net/bridge/br_fdb.c ++++ b/net/bridge/br_fdb.c +@@ -602,6 +602,7 @@ void br_fdb_update(struct net_bridge *br + /* fastpath: update of existing entry */ + if (unlikely(source != fdb->dst && + !test_bit(BR_FDB_STICKY, &fdb->flags))) { ++ br_switchdev_fdb_notify(fdb, RTM_DELNEIGH); + fdb->dst = source; + fdb_modified = true; + /* Take over HW learned entry */ diff --git a/target/linux/generic/backport-5.15/721-v5.12-net-dsa-be-louder-when-a-non-legacy-FDB-operation-fa.patch b/target/linux/generic/backport-5.15/721-v5.12-net-dsa-be-louder-when-a-non-legacy-FDB-operation-fa.patch new file mode 100644 index 0000000000..f9337590f7 --- /dev/null +++ b/target/linux/generic/backport-5.15/721-v5.12-net-dsa-be-louder-when-a-non-legacy-FDB-operation-fa.patch @@ -0,0 +1,52 @@ +From 2fd186501b1cff155cc4a755c210793cfc0dffb5 Mon Sep 17 00:00:00 2001 +From: Vladimir Oltean <vladimir.oltean@nxp.com> +Date: Wed, 6 Jan 2021 11:51:31 +0200 +Subject: [PATCH] net: dsa: be louder when a non-legacy FDB operation fails + +The dev_close() call was added in commit c9eb3e0f8701 ("net: dsa: Add +support for learning FDB through notification") "to indicate inconsistent +situation" when we could not delete an FDB entry from the port. + +bridge fdb del d8:58:d7:00:ca:6d dev swp0 self master + +It is a bit drastic and at the same time not helpful if the above fails +to only print with netdev_dbg log level, but on the other hand to bring +the interface down. + +So increase the verbosity of the error message, and drop dev_close(). + +Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> +Reviewed-by: Andrew Lunn <andrew@lunn.ch> +Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> +Signed-off-by: Jakub Kicinski <kuba@kernel.org> +--- + net/dsa/slave.c | 10 +++++++--- + 1 file changed, 7 insertions(+), 3 deletions(-) + +--- a/net/dsa/slave.c ++++ b/net/dsa/slave.c +@@ -2112,7 +2112,9 @@ static void dsa_slave_switchdev_event_wo + + err = dsa_port_fdb_add(dp, fdb_info->addr, fdb_info->vid); + if (err) { +- netdev_dbg(dev, "fdb add failed err=%d\n", err); ++ netdev_err(dev, ++ "failed to add %pM vid %d to fdb: %d\n", ++ fdb_info->addr, fdb_info->vid, err); + break; + } + fdb_info->offloaded = true; +@@ -2127,9 +2129,11 @@ static void dsa_slave_switchdev_event_wo + + err = dsa_port_fdb_del(dp, fdb_info->addr, fdb_info->vid); + if (err) { +- netdev_dbg(dev, "fdb del failed err=%d\n", err); +- dev_close(dev); ++ netdev_err(dev, ++ "failed to delete %pM vid %d from fdb: %d\n", ++ fdb_info->addr, fdb_info->vid, err); + } ++ + break; + } + rtnl_unlock(); diff --git a/target/linux/generic/backport-5.15/722-v5.12-net-dsa-don-t-use-switchdev_notifier_fdb_info-in-dsa.patch b/target/linux/generic/backport-5.15/722-v5.12-net-dsa-don-t-use-switchdev_notifier_fdb_info-in-dsa.patch new file mode 100644 index 0000000000..c1aa8fda82 --- /dev/null +++ b/target/linux/generic/backport-5.15/722-v5.12-net-dsa-don-t-use-switchdev_notifier_fdb_info-in-dsa.patch @@ -0,0 +1,226 @@ +From c4bb76a9a0ef87c4cc1f636defed5f12deb9f5a7 Mon Sep 17 00:00:00 2001 +From: Vladimir Oltean <vladimir.oltean@nxp.com> +Date: Wed, 6 Jan 2021 11:51:32 +0200 +Subject: [PATCH] net: dsa: don't use switchdev_notifier_fdb_info in + dsa_switchdev_event_work + +Currently DSA doesn't add FDB entries on the CPU port, because it only +does so through switchdev, which is associated with a net_device, and +there are none of those for the CPU port. + +But actually FDB addresses on the CPU port have some use cases of their +own, if the switchdev operations are initiated from within the DSA +layer.

There + are cases where it might never find out though. Either way, DSA today + does not process that notification in any way. +- the hardware FDB of the DSA switch on AP 1 may learn autonomously that + Client B can be reached via swp0, if it receives any packet with + Client 1's source MAC address over Ethernet. +- the hardware FDB of the DSA switch on AP 2 still thinks that Client B + can be reached via swp0. It does not know that it has roamed to wlan0, + because it doesn't perform SA learning from the CPU port. + +Now Client A contacts Client B. +AP 1 routes the packet fine towards swp0 and delivers it on the Ethernet +segment. +AP 2 sees a frame on swp0 and its fdb says that the destination is swp0. +Hairpinning is disabled => drop. + +This problem comes from the fact that these switches have a 'blind spot' +for addresses coming from software bridging. The generic solution is not +to assume that hardware learning can be enabled somehow, but to listen +to more bridge learning events. It turns out that the bridge driver does +learn in software from all inbound frames, in __br_handle_local_finish. +A proper SWITCHDEV_FDB_ADD_TO_DEVICE notification is emitted for the +addresses serviced by the bridge on 'foreign' interfaces. The software +bridge also does the right thing on migration, by notifying that the old +entry is deleted, so that does not need to be special-cased in DSA. When +it is deleted, we just need to delete our static FDB entry towards the +CPU too, and wait. + +The problem is that DSA currently only cares about SWITCHDEV_FDB_ADD_TO_DEVICE +events received on its own interfaces, such as static FDB entries. + +Luckily we can change that, and DSA can listen to all switchdev FDB +add/del events in the system and figure out if those events were emitted +by a bridge that spans at least one of DSA's own ports. In case that is +true, DSA will also offload that address towards its own CPU port, in +the eventuality that there might be bridge clients attached to the DSA +switch who want to talk to the station connected to the foreign +interface. + +In terms of implementation, we need to keep the fdb_info->added_by_user +check for the case where the switchdev event was targeted directly at a +DSA switch port. But we don't need to look at that flag for snooped +events. So the check is currently too late, we need to move it earlier. +This also simplifies the code a bit, since we avoid uselessly allocating +and freeing switchdev_work. + +We could probably do some improvements in the future. For example, +multi-bridge support is rudimentary at the moment. If there are two +bridges spanning a DSA switch's ports, and both of them need to service +the same MAC address, then what will happen is that the migration of one +of those stations will trigger the deletion of the FDB entry from the +CPU port while it is still used by other bridge. That could be improved +with reference counting but is left for another time. + +This behavior needs to be enabled at driver level by setting +ds->assisted_learning_on_cpu_port = true. This is because we don't want +to inflict a potential performance penalty (accesses through +MDIO/I2C/SPI are expensive) to hardware that really doesn't need it +because address learning on the CPU port works there. + +Reported-by: DENG Qingfang <dqfext@gmail.com> +Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> +Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> +Reviewed-by: Andrew Lunn <andrew@lunn.ch> +Signed-off-by: Jakub Kicinski <kuba@kernel.org> +--- + include/net/dsa.h | 5 +++++ + net/dsa/slave.c | 66 +++++++++++++++++++++++++++++++++++++++++++++---------- + 2 files changed, 60 insertions(+), 11 deletions(-) + +--- a/include/net/dsa.h ++++ b/include/net/dsa.h +@@ -317,6 +317,11 @@ struct dsa_switch { + */ + bool untag_bridge_pvid; + ++ /* Let DSA manage the FDB entries towards the CPU, based on the ++ * software bridge database. ++ */ ++ bool assisted_learning_on_cpu_port; ++ + /* In case vlan_filtering_is_global is set, the VLAN awareness state + * should be retrieved from here and not from the per-port settings. + */ +--- a/net/dsa/slave.c ++++ b/net/dsa/slave.c +@@ -2149,6 +2149,28 @@ static void dsa_slave_switchdev_event_wo + dev_put(dp->slave); + } + ++static int dsa_lower_dev_walk(struct net_device *lower_dev, ++ struct netdev_nested_priv *priv) ++{ ++ if (dsa_slave_dev_check(lower_dev)) { ++ priv->data = (void *)netdev_priv(lower_dev); ++ return 1; ++ } ++ ++ return 0; ++} ++ ++static struct dsa_slave_priv *dsa_slave_dev_lower_find(struct net_device *dev) ++{ ++ struct netdev_nested_priv priv = { ++ .data = NULL, ++ }; ++ ++ netdev_walk_all_lower_dev_rcu(dev, dsa_lower_dev_walk, &priv); ++ ++ return (struct dsa_slave_priv *)priv.data; ++} ++ + /* Called under rcu_read_lock() */ + static int dsa_slave_switchdev_event(struct notifier_block *unused, + unsigned long event, void *ptr) +@@ -2167,10 +2189,37 @@ static int dsa_slave_switchdev_event(str + return notifier_from_errno(err); + case SWITCHDEV_FDB_ADD_TO_DEVICE: + case SWITCHDEV_FDB_DEL_TO_DEVICE: +- if (!dsa_slave_dev_check(dev)) +- return NOTIFY_DONE; ++ fdb_info = ptr; ++ ++ if (dsa_slave_dev_check(dev)) { ++ if (!fdb_info->added_by_user) ++ return NOTIFY_OK; ++ ++ dp = dsa_slave_to_port(dev); ++ } else { ++ /* Snoop addresses learnt on foreign interfaces ++ * bridged with us, for switches that don't ++ * automatically learn SA from CPU-injected traffic ++ */ ++ struct net_device *br_dev; ++ struct dsa_slave_priv *p; ++ ++ br_dev = netdev_master_upper_dev_get_rcu(dev); ++ if (!br_dev) ++ return NOTIFY_DONE; ++ ++ if (!netif_is_bridge_master(br_dev)) ++ return NOTIFY_DONE; ++ ++ p = dsa_slave_dev_lower_find(br_dev); ++ if (!p) ++ return NOTIFY_DONE; + +- dp = dsa_slave_to_port(dev); ++ dp = p->dp->cpu_dp; ++ ++ if (!dp->ds->assisted_learning_on_cpu_port) ++ return NOTIFY_DONE; ++ } + + if (!dp->ds->ops->port_fdb_add || !dp->ds->ops->port_fdb_del) + return NOTIFY_DONE; +@@ -2185,18 +2234,13 @@ static int dsa_slave_switchdev_event(str + switchdev_work->port = dp->index; + switchdev_work->event = event; + +- fdb_info = ptr; +- +- if (!fdb_info->added_by_user) { +- kfree(switchdev_work); +- return NOTIFY_OK; +- } +- + ether_addr_copy(switchdev_work->addr, + fdb_info->addr); + switchdev_work->vid = fdb_info->vid; + +- dev_hold(dev); ++ /* Hold a reference on the slave for dsa_fdb_offload_notify */ ++ if (dsa_is_user_port(dp->ds, dp->index)) ++ dev_hold(dev); + dsa_schedule_work(&switchdev_work->work); + break; + default: diff --git a/target/linux/generic/backport-5.15/730-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch b/target/linux/generic/backport-5.15/730-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch new file mode 100644 index 0000000000..f3a6f948ad --- /dev/null +++ b/target/linux/generic/backport-5.15/730-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch @@ -0,0 +1,84 @@ +From c3b8e07909dbe67b0d580416c1a5257643a73be7 Mon Sep 17 00:00:00 2001 +From: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com> +Date: Fri, 12 Mar 2021 00:07:03 -0800 +Subject: [PATCH] net: dsa: mt7530: setup core clock even in TRGMII mode + +A recent change to MIPS ralink reset logic made it so mt7530 actually +resets the switch on platforms such as mt7621 (where bit 2 is the reset +line for the switch).

It will not work with +PCI devices (e.g. of an integrated root complex) and esp. not with DSA +ports. + +There is an of_* variant of the nvmem binding which works without +devices. The returned data of a nvmem_cell_read() has to be freed after +use. On the other hand the return of_get_mac_address() points to some +static data without a lifetime. The trick for now, was to allocate a +device resource managed buffer which is then returned. This will only +work if we have an actual device. + +Change it, so that the caller of of_get_mac_address() has to supply a +buffer where the MAC address is written to. Unfortunately, this will +touch all drivers which use the of_get_mac_address(). + +Usually the code looks like: + + const char *addr; + addr = of_get_mac_address(np); + if (!IS_ERR(addr)) + ether_addr_copy(ndev->dev_addr, addr); + +This can then be simply rewritten as: + + of_get_mac_address(np, ndev->dev_addr); + +Sometimes is_valid_ether_addr() is used to test the MAC address. +of_get_mac_address() already makes sure, it just returns a valid MAC +address. Thus we can just test its return code. But we have to be +careful if there are still other sources for the MAC address before the +of_get_mac_address(). In this case we have to keep the +is_valid_ether_addr() call. + +The following coccinelle patch was used to convert common cases to the +new style.

the recent ability to deal gracefully with upper +interfaces it cannot offload, such as the bridge, bonding or team +drivers. When such uppers exist, the ports are still in standalone mode +as far as the hardware is concerned. + +But when we deliver packets to the software bridge in order for that to +do the forwarding, there is an unpleasant surprise in that the bridge +will refuse to forward them. This is because we unconditionally set +skb->offload_fwd_mark = true, meaning that the bridge thinks the frames +were already forwarded in hardware by us. + +Since dp->bridge_dev is populated only when there is hardware offload +for it, but not in the software fallback case, let's introduce a new +helper that can be called from the tagger data path which sets the +skb->offload_fwd_mark accordingly to zero when there is no hardware +offload for bridging. This lets the bridge forward packets back to other +interfaces of our switch, if needed. + +Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> +Reviewed-by: Tobias Waldekranz <tobias@waldekranz.com> +Signed-off-by: David S.

For example, when client C sends a packet to +A, the FDB lookup will indicate that it should be forwarded to swp0, but +the port matrix of swp3 and swp4 is configured to only allow the CPU to +be its destination, so it is dropped. + +However, this issue does not happen if the bridge is VLAN-aware. That is +because VLAN-aware bridges use independent VLAN learning, i.e. use VID +for FDB lookup, on offloaded ports. As swp3 and swp4 are not offloaded, +shared VLAN learning with default filter ID of 0 is used instead. So the +lookup for A with filter ID 0 never hits and the packet can be forwarded +to the CPU. + +In the current code, only two combinations were used to toggle user +ports' VLAN awareness: one is PCR.PORT_VLAN set to port matrix mode with +PVC.VLAN_ATTR set to transparent port, the other is PCR.PORT_VLAN set to +security mode with PVC.VLAN_ATTR set to user port. + +It turns out that only PVC.VLAN_ATTR contributes to VLAN awareness, and +port matrix mode just skips the VLAN table lookup. The reference manual +is somehow misleading when describing PORT_VLAN modes. It states that +PORT_MEM (VLAN port member) is used for destination if the VLAN table +lookup hits, but actually **PORT_MEM & PORT_MATRIX** (bitwise AND of +VLAN port member and port matrix) is used instead, which means we can +have two or more separate VLAN-aware bridges with the same PVID and +traffic won't leak between them. + +Therefore, to solve this, enable independent VLAN learning with PVID 0 +on VLAN-unaware bridges, by setting their PCR.PORT_VLAN to fallback +mode, while leaving standalone ports in port matrix mode. The CPU port +is always set to fallback mode to serve those bridges. + +During testing, it is found that FDB lookup with filter ID of 0 will +also hit entries with VID 0 even with independent VLAN learning. To +avoid that, install all VLANs with filter ID of 1. + +Signed-off-by: DENG Qingfang <dqfext@gmail.com> +Reviewed-by: Vladimir Oltean <olteanv@gmail.com> +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 { + };
