2017-06-17net: dsa: Fix legacy probingFlorian Fainelli1-11/+8
After commit 6d3c8c0dd88a ("net: dsa: Remove master_netdev and use dst->cpu_dp->netdev") and a29342e73911 ("net: dsa: Associate slave network device with CPU port") we would be seeing NULL pointer dereferences when accessing dst->cpu_dp->netdev too early. In the legacy code, we actually know early in advance the master network device, so pass it down to the relevant functions.

2017-06-16net: dsa: add cross-chip multicast supportVivien Didelot1-10/+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.

2017-06-15net: dsa: assign default CPU port to all portsVivien Didelot1-11/+19
The current code only assigns the default cpu_dp to all user ports of the switch to which the CPU port belongs. The user ports of the other switches of the fabric thus don't have a default CPU port. This patch fixes this by assigning the cpu_dp of all user ports of all switches of the fabric when the tree is fully parsed.

In preparation for supporting multiple CPU ports, remove dst->master_netdev and ds->master_netdev and replace them with only one instance of the common object we have for a port: struct dsa_port::netdev. ds->master_netdev is currently write only and would be helpful in the case where we have two switches, both with CPU ports, and also connected within each other, which the multi-CPU port patch series would address.

2017-06-08net: dsa: add CPU and DSA ports as VLAN membersVivien Didelot1-0/+3
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.

2017-06-08net: dsa: check VLAN capability of every switchVivien Didelot1-10/+17
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.

2017-06-04net: dsa: Fix stale cpu_switch reference after unbind then bindFlorian Fainelli1-1/+3
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().

2017-05-24net: dsa: support cross-chip ageing timeVivien Didelot3-6/+0
Now that the switchdev bridge ageing time attribute is propagated to all switch chips of the fabric, each switch can check if the requested value is valid and program itself, so that the whole fabric shares a common ageing time setting. This is especially needed for switch chips in between others, containing no bridge port members but evidently used in the data path. To achieve that, remove the condition which skips the other switches. We also don't need to identify the target switch anymore, thus remove the sw_index member of the dsa_notifier_ageing_time_info notifier structure.

Instead of having multiple STP state helpers scoping a slave device supporting both the DSA logic and the switchdev binding, provide a single dsa_port_set_state helper scoping a DSA port, as well as its dsa_port_set_state_now wrapper which skips the prepare phase. This allows us to better separate the DSA logic from the slave device handling.

2017-05-18net: dsa: include switchdev.h only onceVivien Didelot1-1/+0
DSA drivers and core use switchdev. Include switchdev.h only once, in the dsa.h public header, so that inclusion in DSA drivers or forward declarations of switchdev structures in not necessary anymore.

2017-05-18net: dsa: include dsa.h only onceVivien Didelot13-12/+14
The public include/net/dsa.h file is meant for DSA drivers, while all DSA core files share a common private header net/dsa/dsa_priv.h file. Ensure that dsa_priv.h is the only DSA core file to include net/dsa.h, and add a new line to separate absolute and relative headers at the same time.
