| * net/mlx4_en: Use affinity hintYuval Atias2014-06-113-2/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The “affinity hint” mechanism is used by the user space daemon, irqbalancer, to indicate a preferred CPU mask for irqs. Irqbalancer can use this hint to balance the irqs between the cpus indicated by the mask. We wish the HCA to preferentially map the IRQs it uses to numa cores close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that sets the affinity hint according the following policy: First it maps IRQs to “close” numa cores. If these are exhausted, the remaining IRQs are mapped to “far” numa cores. Signed-off-by: Yuval Atias <yuvala@mellanox.com> Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

| * net/mlx4_core: Keep only one driver entry release mlx4_privWei Yang2014-06-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following commit befdf89 "net/mlx4_core: Preserve pci_dev_data after __mlx4_remove_one()", there are two mlx4 pci callbacks which will attempt to release the mlx4_priv object -- .shutdown and .remove. This leads to a use-after-free access to the already freed mlx4_priv instance and trigger a "Kernel access of bad area" crash when both .shutdown and .remove are called. During reboot or kexec, .shutdown is called, with the VFs probed to the host going through shutdown first and then the PF. Later, the PF will trigger VFs' .remove since VFs still have driver attached. Fix that by keeping only one driver entry which releases mlx4_priv.

| * net/mlx4_core: Fix SRIOV free-pool management when enforcing resource quotasJack Morgenstein2014-06-111-4/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hypervisor driver tracks free slots and reserved slots at the global level and tracks allocated slots and guaranteed slots per VF. Guaranteed slots are treated as reserved by the driver, so the total reserved slots is the sum of all guaranteed slots over all the VFs. As VFs allocate resources, free (global) is decremented and allocated (per VF) is incremented for those resources. However, reserved (global) is never changed. This means that effectively, when a VF allocates a resource from its guaranteed pool, it is actually reducing that resource's free pool (since the global reserved count was not also reduced). The fix for this problem is the following: For each resource, as long as a VF's allocated count is <= its guaranteed number, when allocating for that VF, the reserved count (global) should be reduced by the allocation as well. When the global reserved count reaches zero, the remaining global free count is still accessible as the free pool for that resource. When the VF frees resources, the reverse happens: the global reserved count for a resource is incremented only once the VFs allocated number falls below its guaranteed number.

VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: David S.

It occurs due to a simultaneous access to priv->mac_hash from two contexts. The buggy scenario described below: Context 1: copy the new mac address to the dev->dev_addr field. Context 2: mlx4_en_do_uc_filter removes prev_mac entry from the mac_hash db since it is not in dev->uc and not equal to dev->dev_addr. Context 1: mlx4_en_do_set_mac() calls mlx4_en_replace_mac() to replace prev_mac with dev_addr but it fails to update the mac_hash db since it no longer contains prev_mac, therefore it returns with an error. The fix is to prevent mlx4_en_do_uc_filter from being executed by both of the context 1 calls described above, This is done by putting them both under the mdev->state_lock lock, it will solve this issue since mlx4_en_do_uc_filter is already protected by the mdev->state_lock.

Set the port down. 2. Change the MAC address - mlx4_en_set_mac() will change dev->dev_addr. 3. Set the port up - will result in mlx4_en_do_uc_filter that will remove the prev_mac entry from the mac_hash db. 4. Changing the MAC address again will eventually trigger the call to mlx4_en_replace_mac() in order to replace prev_mac with dev_addr but the prev_mac entry is already not exist in the mac_hash db therefore the operation fails. The fix is to set the prev_mac with the new MAC address so in step 3 above, after setting the port up mlx4_en_get_qp() is updating the mac_hash with the entry of dev_addr which is equal to prev_mac. Therefore in step 4, when calling mlx4_en_replace_mac, the entry related to prev_mac exist in mac_hash and the replace operation succeed.

By default, no VFs are enabled for QP0 operation. To enable QP0 operation on a VF/port, under /sys/class/infiniband/mlx4_x/iov/<b:d:f>/ports/x there are two new entries: - smi_enabled (read-only). Indicates whether smi is currently enabled for the indicated VF/port - enable_smi_admin (rw). Used by the admin to request that smi capability be enabled or disabled for the indicated VF/port. 0 = disable, 1 = enable. The requested enablement will occur at the next reset of the VF (e.g. driver restart on the VM which owns the VF).

Additionally, for these enabled VFs, their QP0 proxy and tunnel QPs are MLX QPs. As such, they operate over VL15. Therefore, they are not affected by "credit" problems or changes in the VLArb table (which may shut down VL0). Non-enabled VFs may only create UD proxy QP0 qps (which are forced by the hypervisor to send packets using the q-key it assigns and places in the qp-context). Thus, non-enabled VFs will not pose a security risk. The hypervisor discards any privileged MADs it receives from these non-enabled VFs. By default, all VFs are NOT enabled, and must explicitly be enabled by the administrator. The sysfs interface which operates the VF enablement infrastructure is provided in the next commit.

The main reason for this decision is security, since Subnet Management Datagrams (SMPs) are not restricted by network partitioning and may affect the physical network topology. Moreover, even the SM may be denied access from portions of the network by setting management keys unknown to the SM. However, it is desirable to grant SMI access to certain privileged VFs, so that certain network management activities may be conducted within virtual machines instead of the hypervisor. This commit does the following: 1. Create QP0 tunnel QPs for all VFs. 2. Discard SMI mads sent-from/received-for non-privileged VFs in the hypervisor MAD multiplex/demultiplex logic. SMI mads from/for privileged VFs are allowed to pass. 3. MAD_IFC wrapper changes/fixes. For non-privileged VFs, only host-view MAD_IFC commands are allowed, and only for SMI LID-Routed GET mads. For privileged VFs, there are no restrictions. This commit does not allow privileged VFs as yet. To determine if a VF is privileged, it calls function mlx4_vf_smi_enabled(). This function returns 0 unconditionally for now. The next two commits allow defining and activating privileged VFs.

As with the MAC and VLAN tables, we now use a mutex per port for the GID table so that modifying the driver copy and modifying the firmware copy of a port GID table becomes an atomic operation (thus avoiding driver-copy/FW-copy mismatches).
