* cxgb4: Add control net_device for configuring PCIe VFHariprasad Shenai2016-08-151-18/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: For instance, the current APIs assume a 1-to-1 mapping of Network Ports, Physical Functions and the SR-IOV Virtual Functions of those Physical Functions. This is not the case with our cards where any Virtual Function can be hooked up to any Port -- or any number of Ports the current Linux APIs also assume only 1 Network Interface/Port can be accessed per Virtual Function. Another issue is that these APIs assume that the Administrative Driver is attached to the Physical Function Associated with a Virtual Function. This is not the case with our card where all administration is performed by a Driver which is not attached to any of the Physical Functions which have SR-IOV PCI Capabilities. Another consequence of these assumptions is the inability to utilize all of the cards SR-IOV resources. For instance, our cards have SR-IOV Capabilities on Physical Functions 0..3 and the administrative Driver attaches to Physical Function 4. Each of the Physical Functions 0..3 can support up to 16 Virtual Functions. With the current Linux APIs, a 2-Port card would only be able to use the Virtual Functions on Physical Function 0..1 and not allow the Virtual Functions on Physical Functions 2..3 to be used since there are no Ports 2..3 on a 2-Port card. Fix: Since the control node is always the netdevice for all VF ACL commands. Created a dummy netdevice for each Physical Function from 0 to 3 through which one could control their VFs. The device won't be associated with any port, since it doesn't need to transmit/receive. Its purely used for VF management purpose only. The device will be registered only when VF for a particular PF is configured using PCI sysfs interface and unregistered while pci_disable_sriov() for the PF is called.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dmitry Torokhov says: ==================== Make /proc per net namespace objects belong to container Currently [almost] all /proc objects belong to the global root, even if data belongs to a given namespace within a container and (at least for sysctls) we work around permssions checks to allow container's root to access the data. This series changes ownership of net namespace /proc objects (/proc/net/self/* and /proc/sys/net/*) to be container's root and not global root when there exists mapping for container's root in user namespace. This helps when running Android CTS in a container, but I think it makes sense regardless. Changes from V1: - added fix for crash when !CONFIG_NET_NS (new patch #1) - addressed Eric'c comments for error handling style in patch #3 and added his Ack - adjusted patch #2 to use the same style of erro handling - sent out as series instead of separate patches ==================== Signed-off-by: David S.

| * net: make net namespace sysctls belong to container's ownerDmitry Torokhov2016-08-153-9/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If net namespace is attached to a user namespace let's make container's root owner of sysctls affecting said network namespace instead of global root. This also allows us to clean up net_ctl_permissions() because we do not need to fudge permissions anymore for the container's owner since it now owns the objects in question. Acked-by: "Eric W.

| | | | | | | | | | | | | | | | | | | | | | | | There are certain parameters that belong to net namespace and that are exported in /proc. They should be controllable by the container's owner, but are currently owned by global root and thus not available. Let's change proc code to inherit ownership of parent entry, and when create per-ns "net" proc entry set it up as owned by container's owner.

| * netns: do not call pernet ops for not yet set up init_net namespaceDmitry Torokhov2016-08-151-4/+17
|/ | | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_NET_NS is disabled, registering pernet operations causes init() to be called immediately with init_net as an argument. Unfortunately this leads to some pernet ops, such as proc_net_ns_init() to be called too early, when init_net namespace has not been fully initialized. This causes issues when we want to change pernet ops to use more data from the net namespace in question, for example reference user namespace that owns our network namespace. To fix this we could either play game of musical chairs and rearrange init order, or we could do the same as when CONFIG_NET_NS is enabled, and postpone calling pernet ops->init() until namespace is set up properly. Note that we can not simply undo commit ed160e839d2e ("[NET]: Cleanup pernet operation without CONFIG_NET_NS") and use the same implementations for __register_pernet_operations() and __unregister_pernet_operations(), because many pernet ops are marked as __net_initdata and will be discarded, which wreaks havoc on our ops lists. Here we rely on the fact that we only use lists until init_net is fully initialized, which happens much earlier than discarding __net_initdata sections.

| * | net: thunderx: Add RGMII interface type supportSunil Goutham2016-08-136-33/+332
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds RGX/RGMII interface type support to BGX driver. This type of interface is supported by 81xx SOC. CN81XX VNIC has 8 VFs and max possible LMAC interfaces are 9, hence RGMII interface will not work if all DLMs are in BGX mode and all 8 LMACs are enabled Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for BGX module on 81xx where a BGX can be split and have different LMACs configured in different modes. Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | net: thunderx: Support for different LMAC types within BGXSunil Goutham2016-08-132-136/+98Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 88xx all LMACs in a BGX will be in same mode but on 81xx BGX can be split as two and there can be LMACs configured in different modes. These changes move lmac_type, lane2serdes fields into per lmac struct from BGX struct. Got rid of qlm_mode field which has become redundant with these changes. And now no of valid LMACs is read from CSRs configured by low level firmware and figuring out the same based on QLM mode is discarded Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: David S.

| * | net: thunderx: Enable mailbox interrupts on 81xx/83xxSunil Goutham2016-08-131-38/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 88xx has 128 VFs, 81xx has 8 VFs and 83xx will have 32VFs. Made changes to PF driver such that mailbox interrupt enable registers are configuired based on number of VFs HW supports. Also cleanedup mailbox irq handler registration code.
