Vladimir Oltean says: ==================== Cleanup for the bridge replay helpers This patch series brings some improvements to the logic added to the bridge and DSA to handle LAG interfaces sandwiched between a bridge and a DSA switch port. br0 / \ / \ bond0 swp2 / \ / \ swp0 swp1 In particular, it ensures that the switchdev object additions and deletions are well balanced per physical port. This is important for future work in the area of offloading local bridge FDB entries to hardware in the context of DSA requesting a replay of those entries at bridge join time (this will be submitted in a future patch series). Due to some difficulty ensuring that the deletion of local FDB entries pointing towards the bridge device itself is notified to switchdev in time (before the switchdev port disconnects from the bridge), this is potentially still not the final form in which the replay helpers will exist. I'm thinking about moving from the pull mode (in which DSA requests the replay) to a push mode (in which the bridge initiates the replay). Nonetheless, these preliminary changes are needed either way. The patch series also addresses some feedback from Nikolai which is long overdue by now (sorry). Switchdev driver maintainers were deliberately omitted due to the trivial nature of the driver changes (just a function prototype). Changes in v2: - fix build issue in patch 4 (function prototype mismatch) - move switchdev object unsync to the NETDEV_PRECHANGEUPPER code path ==================== Signed-off-by: -
Vladimir Oltean authored
When a DSA switch port leaves a bonding interface that is under a bridge, there might be dangling switchdev objects on that port left behind, because the bridge is not aware that its lower interface (the bond) changed state in any way. Call the bridge replay helpers with adding=false before changing dp->bridge_dev to NULL, because we need to simulate to dsa_slave_port_obj_del() that these notifications were emitted by the bridge. We add this hook to the NETDEV_PRECHANGEUPPER event handler, because we are calling into switchdev (and the __switchdev_handle_port_obj_del fanout helpers expect the upper/lower adjacency lists to still be valid) and PRECHANGEUPPER is the last moment in time when they still are.

When a switchdev port leaves a LAG that is a bridge port, the switchdev objects and port attributes offloaded to that port are not removed: ip link add br0 type bridge ip link add bond0 type bond mode 802.3ad ip link set swp0 master bond0 ip link set bond0 master br0 bridge vlan add dev bond0 vid 100 ip link set swp0 nomaster VLAN 100 will remain installed on swp0 despite it going into standalone mode, because as far as the bridge is concerned, nothing ever happened to its bridge port. Let's extend the bridge vlan, fdb and mdb replay functions to take a 'bool adding' argument, and make DSA and ocelot call the replay functions with 'adding' as false from the switchdev unsync path, for the switch port that leaves the bridge. Note that this patch in itself does not salvage anything, because in the current pull mode of operation, DSA still needs to call the replay helpers with adding=false. This will be done in another patch. Signed-off-by:

There is a slight inconvenience in the switchdev replay helpers added recently, and this is when: ip link add br0 type bridge ip link add bond0 type bond ip link set bond0 master br0 bridge vlan add dev bond0 vid 100 ip link set swp0 master bond0 ip link set swp1 master bond0 Since the underlying driver (currently only DSA) asks for a replay of VLANs when swp0 and swp1 join the LAG because it is bridged, what will happen is that DSA will try to react twice on the VLAN event for swp0. This is not really a huge problem right now, because most drivers accept duplicates since the bridge itself does, but it will become a problem when we add support for replaying switchdev object deletions. Let's fix this by adding a blank void *ctx in the replay helpers, which will be passed on by the bridge in the switchdev notifications. If the context is NULL, everything is the same as before. But if the context is populated with a valid pointer, the underlying switchdev driver (currently DSA) can use the pointer to 'see through' the bridge port (which in the example above is bond0) and 'know' that the event is only for a particular physical port offloading that bridge port, and not for all of them.

In the case where the driver asks for a replay of a certain type of event (port object or attribute) for a bridge port that is a LAG, it may do so because this port has just joined the LAG. But there might already be other switchdev ports in that LAG, and it is preferable that those preexisting switchdev ports do not act upon the replayed event. The solution is to add a context to switchdev events, which is NULL most of the time (when the bridge layer initiates the call) but which can be set to a value controlled by the switchdev driver when a replay is requested. The driver can then check the context to figure out if all ports within the LAG should act upon the switchdev event, or just the ones that match the context. We have to modify all switchdev_handle_* helper functions as well as the prototypes in the drivers that use these helpers too, because these helpers hide the underlying struct switchdev_notifier_info from us and there is no way to retrieve the context otherwise. The context structure will be populated and used in later patches. Signed-off-by:

Not using this driver, I did not realize it doesn't react to SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE notifications, but it implements just the bridge bypass operations (.ndo_fdb_{add,del}). So the call to br_fdb_replay just produces notifications that are ignored, delete it for now. Signed-off-by: -
Vladimir Oltean authored
Since commit 2c4eca3e ("net: bridge: switchdev: include local flag in FDB notifications"), the bridge emits SWITCHDEV_FDB_ADD_TO_DEVICE events with the is_local flag populated (but we ignore it nonetheless). We would like DSA to start treating this bit, but it is still not populated by the replay helper, so add it there too. Signed-off-by:

FB_MTU is used in 'tipc_msg_build()' to alloc smaller skb when memory allocation fails, which can avoid unnecessary sending failures. The value of FB_MTU now is 3744, and the data size will be: (3744 + SKB_DATA_ALIGN(sizeof(struct skb_shared_info)) + \ SKB_DATA_ALIGN(BUF_HEADROOM + BUF_TAILROOM + 3)) which is larger than one page(4096), and two pages will be allocated. To avoid it, replace '3744' with a calculation: (PAGE_SIZE - SKB_DATA_ALIGN(BUF_OVERHEAD) - \ SKB_DATA_ALIGN(sizeof(struct skb_shared_info))) What's more, alloc_skb_fclone() will call SKB_DATA_ALIGN for data size, and it's not necessary to make alignment for buf_size in tipc_buf_acquire(). So, just remove it. Fixes: 4c94cc2d ("tipc: fall back to smaller MTU if allocation of local send skb fails") Signed-off-by: -

Guillaume Nault says: ==================== net: reset MAC header consistently across L3 virtual devices Some virtual L3 devices, like vxlan-gpe and gre (in collect_md mode), reset the MAC header pointer after they parsed the outer headers. This accurately reflects the fact that the decapsulated packet is pure L3 packet, as that makes the MAC header 0 bytes long (the MAC and network header pointers are equal). However, many L3 devices only adjust the network header after decapsulation and leave the MAC header pointer to its original value. This can confuse other parts of the networking stack, like TC, which then considers the outer headers as one big MAC header. This patch series makes the following L3 tunnels behave like VXLAN-GPE: bareudp, ipip, sit, gre, ip6gre, ip6tnl, gtp. The case of gre is a bit special. It already resets the MAC header pointer in collect_md mode, so only the classical mode needs to be adjusted. However, gre also has a special case that expects the MAC header pointer to keep pointing to the outer header even after decapsulation. Therefore, patch 4 keeps an exception for this case. Ideally, we'd centralise the call to skb_reset_mac_header() in ip_tunnel_rcv(), to avoid manual calls in ipip (patch 2), sit (patch 3) and gre (patch 4). That's unfortunately not feasible currently, because of the gre special case discussed above that precludes us from resetting the MAC header unconditionally. The original motivation is to redirect bareudp packets to Ethernet devices (as described in patch 1). The rest of this series aims at bringing consistency across all L3 devices (apart from gre's special case unfortunately). Note: the gtp patch results from pure code inspection and has been compiled tested only. ==================== Signed-off-by: -

Reset the mac_header pointer even when the tunnel transports only L3 data (in the ARPHRD_ETHER case, this is already done by eth_type_trans). This prevents other parts of the stack from mistakenly accessing the outer header after the packet has been decapsulated. In practice, this allows to push an Ethernet header to ipip6, ip6ip6, mplsip6 or ip6gre packets and redirect them to an Ethernet device: $ tc filter add dev ip6tnl0 ingress matchall \ action vlan push_eth dst_mac 00:00:5e:00:53:01 \ src_mac 00:00:5e:00:53:00 \ action mirred egress redirect dev eth0 Without this patch, push_eth refuses to add an ethernet header because the skb appears to already have a MAC header.

Commit e271c7b4 ("gre: do not keep the GRE header around in collect medata mode") did reset the mac_header for the collect_md case. Let's extend this behaviour to classical gre devices as well. ipgre_header_parse() seems to be the only case that requires mac_header to point to the outer header. We can detect this case accurately by checking ->header_ops. For all other cases, we can reset mac_header. This allows to push an Ethernet header to ipgre packets and redirect them to an Ethernet device: $ tc filter add dev gre0 ingress matchall \ action vlan push_eth dst_mac 00:00:5e:00:53:01 \ src_mac 00:00:5e:00:53:00 \ action mirred egress redirect dev eth0 Before this patch, this worked only for collect_md gre devices. Now this works for regular gre devices as well. Only the special case of gre devices that use ipgre_header_ops isn't supported. Signed-off-by:

Even though sit transports L3 data (IPv6, IPv4 or MPLS) packets, it needs to reset the mac_header pointer, so that other parts of the stack don't mistakenly access the outer header after the packet has been decapsulated. There are two rx handlers to modify: ipip6_rcv() for the ip6ip mode and sit_tunnel_rcv() which is used to re-implement the ipip and mplsip modes of ipip.ko. This allows to push an Ethernet header to sit packets and redirect them to an Ethernet device: $ tc filter add dev sit0 ingress matchall \ action vlan push_eth dst_mac 00:00:5e:00:53:01 \ src_mac 00:00:5e:00:53:00 \ action mirred egress redirect dev eth0 Without this patch, push_eth refuses to add an ethernet header because the skb appears to already have a MAC header.
