* net: dsa: Don't dereference dst->cpu_dp->netdevFlorian Fainelli2017-08-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we do not have a master network device attached dst->cpu_dp will be NULL and accessing cpu_dp->netdev will create a trace similar to the one below. The correct check is on dst->cpu_dp period.

* net: dsa: ksz: fix skb freeingVivien Didelot2017-08-111-4/+9
| | | | | | | | | | | | | | | | The DSA layer frees the original skb when an xmit function returns NULL, meaning an error occurred. But if the tagging code copied the original skb, it is responsible of freeing the copy if an error occurs. The ksz tagging code currently has two issues: if skb_put_padto fails, the skb copy is not freed, and the original skb will be freed twice. To fix that, move skb_put_padto inside both branches of the skb_tailroom condition, before freeing the original skb, and free the copy on error.

* net: dsa: Initialize ds->cpu_port_mask earlierFlorian Fainelli2017-07-251-6/+7
| | | | | | | | | | | | | | | | | | The mt7530 driver has its dsa_switch_ops::get_tag_protocol function check ds->cpu_port_mask to issue a warning in case the configured CPU port is not capable of supporting tags. After commit 14be36c2c96c ("net: dsa: Initialize all CPU and enabled ports masks in dsa_ds_parse()") we slightly re-arranged the initialization such that this was no longer working. Just make sure that ds->cpu_port_mask is set prior to the first call to get_tag_protocol, thus restoring the expected contract. In case of error, the CPU port bit is cleared.

* net: dsa: add cross-chip multicast supportVivien Didelot2017-06-161-10/+20
| | | | | | | | | | | | | | | | | | Similarly to how cross-chip VLAN works, define a bitmap of multicast group members for a switch, now including its DSA ports, so that multicast traffic can be sent to all switches of the fabric. A switch may drop the frames if no user port is a member. This brings support for multicast in a multi-chip environment. As of now, all switches of the fabric must support the multicast operations in order to program a single fabric port.

| | | | | | | | | | | | | | | | | | In a multi-chip switch fabric, it is currently the responsibility of the driver to add the CPU or DSA (interconnecting chips together) ports as members of a new VLAN entry. This makes the drivers more complicated. We want the DSA drivers to be stupid and the DSA core being the one responsible for caring about the abstracted switch logic and topology. Make the DSA core program the CPU and DSA ports as part of the VLAN. This makes all chips of the data path to be aware of VIDs spanning the the whole fabric and thus, seamlessly add support for cross-chip VLAN.

| | | | | | | | | | | | | | | | | | Now that the VLAN object is propagated to every switch chip of the switch fabric, we can easily ensure that they all support the required VLAN operations before modifying an entry on a single switch. To achieve that, remove the condition skipping other target switches, and add a bitmap of VLAN members, eventually containing the target port, if we are programming the switch target. This will allow us to easily add other VLAN members, such as the DSA or CPU ports (to introduce cross-chip VLAN support) or the other port members if we want to reduce hardware accesses later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 9520ed8fb841 ("net: dsa: use cpu_switch instead of ds[0]") replaced the use of dst->ds[0] with dst->cpu_switch since that is functionally equivalent, however, we can now run into an use after free scenario after unbinding then rebinding the switch driver. The use after free happens because we do correctly initialize dst->cpu_switch the first time we probe in dsa_cpu_parse(), then we unbind the driver: dsa_dst_unapply() is called, and we rebind again. dst->cpu_switch now points to a freed "ds" structure, and so when we finally dereference it in dsa_cpu_port_ethtool_setup(), we oops. To fix this, simply set dst->cpu_switch to NULL in dsa_dst_unapply() which guarantees that we always correctly re-assign dst->cpu_switch in dsa_cpu_parse().

| | | | | | | | | | | | | | | | | | | | | | | | Add two new DSA_NOTIFIER_FDB_ADD and DSA_NOTIFIER_FDB_DEL events to notify not only a single switch, but all switches of a the fabric when an FDB entry is added or removed. For the moment, keep the current behavior and ignore other switches.

* | net: dsa: add notifier for ageing timeVivien Didelot2017-05-233-29/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch keeps the port-wide ageing time handling code in dsa_port_ageing_time, pushes the requested ageing time value in a new switch fabric notification, and moves the switch-wide ageing time handling code in dsa_switch_ageing_time. This has the effect that now not only the switch that the target port belongs to can be programmed, but all switches composing the switch fabric. For the moment, keep the current behavior and ignore other switches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DSA notifier events and info structure definitions are not meant for DSA drivers and users, but only used internally by the DSA core files. Move them from the public net/dsa.h file to the private dsa_priv.h file. Also use this opportunity to turn the events into an anonymous enum, because we don't care about the values, and this will prevent future conflicts when adding (and sorting) new events.
