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. This is all switchdev driver private +business, which the notification makes possible. + +All is fine until someone unplugs Station B's cable and moves it to the +other switch: + + DUT + +-------------------------------------+ + | br0 | + | +------+ +------+ +------+ +------+ | + | | | | | | | | | | + | | swp0 | | swp1 | | swp2 | | eth0 | | + +-------------------------------------+ + | | | + Station A | | + | | + +--+------+--+ +--+------+--+ + | | | | | | | | + | | swp0 | | | | swp0 | | + Another | +------+ | | +------+ | Another + switch | br0 | | br0 | switch + | +------+ | | +------+ | + | | | | | | | | + | | swp1 | | | | swp1 | | + +--+------+--+ +--+------+--+ + | + Station B + +Luckily for the use cases we care about, Station B is noisy enough that +the DUT hears it (on swp1 this time). swp1 receives the frames and +delivers them to the bridge, who enters the unlikely path in br_fdb_update +of updating an existing entry. 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.

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 +Signed-off-by: Vladimir Oltean +Reviewed-by: Florian Fainelli +Reviewed-by: Andrew Lunn +Signed-off-by: Jakub Kicinski +--- + 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-5.10/730-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch b/target/linux/generic/backport-5.10/730-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-5.10/730-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 +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. Afterwards, I've manually gone over the drivers and fixed the +return code variable: either used a new one or if one was already +available use that.

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.

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.

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 -Signed-off-by: Vladimir Oltean -Reviewed-by: Florian Fainelli -Reviewed-by: Andrew Lunn -Signed-off-by: Jakub Kicinski ---- - 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-5.10/780-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch b/target/linux/generic/backport-5.10/780-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch deleted file mode 100644 index f3a6f948ad..0000000000 --- a/target/linux/generic/backport-5.10/780-net-dsa-mt7530-setup-core-clock-even-in-TRGMII-mode.patch +++ /dev/null @@ -1,84 +0,0 @@ -From c3b8e07909dbe67b0d580416c1a5257643a73be7 Mon Sep 17 00:00:00 2001 -From: Ilya Lipnitskiy -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).

the bridge - -DSA has gained 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 -Reviewed-by: Tobias Waldekranz -Signed-off-by: David S.
