Scott Feldman says: ==================== rocker: enable by default untagged VLAN support This patch set is a followup to Simon Horman's RFC patch: [PATCH/RFC net-next] rocker: by default accept untagged packets Now, on port probe, we install untagged VLAN (vid=0) support for each port as the default. This is equivalent to the command: bridge vlan add vid 0 dev DEV self Accepting untagged VLAN pkts is a reasonable default, but the user could override this with: bridge vlan del vid 0 dev DEV self With this, we no longer need 8021q module to install vid=0 when port interface opens. In fact, we don't need support for legacy VLAN ndo ops at all since they're superseded by bridge_setlink/dellink. So remove legacy VLAN ndo ops support in driver. (The legacy VLAN ndo ops are supported by bonding/team drivers, but don't fit into the transaction model offered by switchdev, so switching all VLAN functions to bridge_setlink/dellink switchdev support gets us stacked driver + transaction model support). ==================== Signed-off-by: -

Remove support for legacy ndo ops .ndo_vlan_rx_add_vid/.ndo_vlan_rx_kill_vid. Rocker will use bridge_setlink/dellink exclusively for VLAN add/del operations. The legacy ops are needed if using 8021q driver module to setup VLANs on the port. But an alternative exists in using bridge_setlink/delink to setup VLANs, which doesn't depend on 8021q module. So rocker will switch to the newer setlink/dellink ops. VLANs can added/delete from the port, regardless if port is bridged or not, using the bridge commands: bridge vlan [add|del] vid VID dev DEV self (Yes, I agree it's confusing to use the "bridge" command to set a VLAN on a non-bridged port). Using setlink/dellink over legacy ops let's us handle the stacked driver case automatically. It's built-in. setlink also pass additional flags (PVID, egress untagged) that aren't available with the legacy ops. Signed-off-by:

When the port joins a bridge, the port's internal VLAN ID needs to change to the bridge's internal VLAN ID. Likewise, when leaving the bridge, the internal VLAN ID reverts back the port's original internal VLAN ID. (The internal VLAN ID is used by device to internally mark untagged pkts with some VLAN, which will eventually be removed on egress...think PVID). When the internal VLAN ID changes, we need to update the VLAN table entries and the router MAC entries for IP/IPv6 to reflect the new internal VLAN ID. This patch makes use of the common rocker_port_vlan_add/del functions to make sure the tables are updated for the current internal VLAN ID. Signed-off-by:

On port probe, install by default untagged VLAN support. This is equivalent to running the command: bridge vlan add vid 0 dev DEV self A user could, if they wanted, manaully removing untagged support from the port by running the command: bridge vlan del vid 0 dev DEV self But installing it by default on port initialization gives the normal expected behavior.

When allocating the array of rocker port pointers, zero the array values so we can test for !NULL to see if port is allocated/registered. We'll need this later when installing untagged VLAN support for each port, during port probe. It's a long story, but to install a VLAN (vid=0 for untagged, in this case) on a port, we'll need to scan other ports to see if the VLAN group for that VLAN has been setup. To scan the other ports, we need to walk the port array. Signed-off-by:

The driver allocates one page for each buffer on the rx ring, which is too much on architectures like ppc64 and can cause unexpected allocation failures when the system is under stress. Now, we keep a memory pool per queue, and if the architecture's PAGE_SIZE is greater than 4k, we fragment pages and assign each 4k segment to a ring element, which reduces the overall memory consumption on such architectures. This helps avoiding errors like the example below: [bnx2x_alloc_rx_sge:435(eth1)]Can't alloc sge [c00000037ffeb900] [d000000075eddeb4] .bnx2x_alloc_rx_sge+0x44/0x200 [bnx2x] [c00000037ffeb9b0] [d000000075ee0b34] .bnx2x_fill_frag_skb+0x1ac/0x460 [bnx2x] [c00000037ffebac0] [d000000075ee11f0] .bnx2x_tpa_stop+0x160/0x2e8 [bnx2x] [c00000037ffebb90] [d000000075ee1560] .bnx2x_rx_int+0x1e8/0xc30 [bnx2x] [c00000037ffebcd0] [d000000075ee2084] .bnx2x_poll+0xdc/0x3d8 [bnx2x] (unreliable) Signed-off-by:

If new optional attribute OVS_USERSPACE_ATTR_ACTIONS is added to an OVS_ACTION_ATTR_USERSPACE action, then include the datapath actions in the upcall. This Directly associates the sampled packet with the path it takes through the virtual switch. Path information currently includes mangling, encapsulation and decapsulation actions for tunneling protocols GRE, VXLAN, Geneve, MPLS and QinQ, but this extension requires no further changes to accommodate datapath actions that may be added in the future. Adding path information enhances visibility into complex virtual networks. Signed-off-by:

When we scan a packet for GRO processing, we want to see the most common packet types in the front of the offload_base list. So add a priority field so we can handle this properly. IPv4/IPv6 get the highest priority with the implicit zero priority field. Next comes ethernet with a priority of 10, and then we have the MPLS types with a priority of 15. Suggested-by:

Commit dff173de ("bnx2x: Fix statistics locking scheme") changed the bnx2x locking around statistics state into using a mutex - but the lock is being accessed via a timer which is forbidden. [If compiled with CONFIG_DEBUG_MUTEXES, logs show a warning about accessing the mutex in interrupt context] This moves the implementation into using a semaphore [with size '1'] instead.

When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.

sparc: Resolve conflict between sparc v9 and M7 on usage of bit 9 of TTE Bit 9 of TTE is CV (Cacheable in V-cache) on sparc v9 processor while the same bit 9 is MCDE (Memory Corruption Detection Enable) on M7 processor. This creates a conflicting usage of the same bit. Kernel sets TTE.cv bit on all pages for sun4v architecture which works well for sparc v9 but enables memory corruption detection on M7 processor which is not the intent. This patch adds code to determine if kernel is running on M7 processor and takes steps to not enable memory corruption detection in TTE erroneously. Signed-off-by:
