The current codes use _IOC_TYPE(cmd) == 0x89 to check if the cmd is one socket ioctl command like SIOCGIFHWADDR. But the literal number 0x89 may confuse readers. So create one macro SOCK_IOC_TYPE to enhance the readability. Signed-off-by:

Each socket operates in a network namespace where it has been created, so if we want to dump and restore a socket, we have to know its network namespace. We have a socket_diag to get information about sockets, it doesn't report sockets which are not bound or connected. This patch introduces a new socket ioctl, which is called SIOCGSKNS and used to get a file descriptor for a socket network namespace. A task must have CAP_NET_ADMIN in a target network namespace to use this ioctl. Cc: "David S. Miller" <davem@davemloft.net> Cc: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by:

Saeed Mahameed says: ==================== Mellanox mlx5 core driver updates 2016-10-25 This series contains some updates and fixes of mlx5 core and IB drivers with the addition of two features that demand new low level commands and infrastructure updates. - SRIOV VF max rate limit support - mlx5e tc support for FWD rules with counter. Needed for both net and rdma subsystems. Updates and Fixes: From Saeed Mahameed (2): - mlx5 IB: Skip handling unknown mlx5 events - Add ConnectX-5 PCIe 4.0 VF device ID From Artemy Kovalyov (2): - Update struct mlx5_ifc_xrqc_bits - Ensure SRQ physical address structure endianness From Eugenia Emantayev (1): - Fix length of async_event_mask New Features: From Mohamad Haj Yahia (3): mlx5 SRIOV VF max rate limit support - Introduce TSAR manipulation firmware commands - Introduce E-switch QoS management - Add SRIOV VF max rate configuration support From Mark Bloch (7): mlx5e Tc support for FWD rule with counter - Don't unlock fte while still using it - Use fte status to decide on firmware command - Refactor find_flow_rule - Group similar rules under the same fte - Add multi dest support - Add option to add fwd rule with counter - mlx5e tc support for FWD rule with counter Mark here fixed two trivial issues with the flow steering core, and did some refactoring in the flow steering API to support adding mulit destination rules to the same hardware flow table entry at once. In the last two patches added the ability to populate a flow rule with a flow counter to the same flow entry. V2: Dropped some patches that added new structures without adding any usage of them. Added SRIOV VF max rate configuration support patch that introduces the usage of the TSAR infrastructure. Added flow steering fixes and refactoring in addition to mlx5 tc support for forward rule with counter. ==================== Signed-off-by: -

Jiri Pirko says: ==================== mlxsw: Add Infiniband support for Mellanox switches This patchset adds basic Infiniband support for SwitchX-2, Switch-IB and Switch-IB-2 ASIC drivers. SwitchX-2 ASIC is VPI capable, which means each port can be either Ethernet or Infiniband. When the port is configured as Infiniband, the Subnet Management Agent (SMA) is managed by the SwitchX-2 firmware and not by the host. Port configuration, MTU and more are configured remotely by the Subnet Manager (SM). Usage: $ devlink port show pci/0000:03:00.0/1: type eth netdev eth0 pci/0000:03:00.0/3: type eth netdev eth1 pci/0000:03:00.0/5: type eth netdev eth2 pci/0000:03:00.0/6: type eth netdev eth3 pci/0000:03:00.0/8: type eth netdev eth4 $ devlink port set pci/0000:03:00.0/1 type ib $ devlink port show pci/0000:03:00.0/1: type ib Switch-IB (FDR) and Switch-IB-2 (EDR 100Gbs) ASICs are Infiniband-only switches. The support provided in the mlxsw_switchib.ko driver is port initialization only. The firmware running in the Silicon implements the SMA. Please note that this patchset does only very basic port initialization. ib_device or RDMA implementations are not part of this patchset. ==================== Signed-off-by: -

SwitchX-2 is IB capable device. This patch add a support to change the port type between Ethernet and Infiniband. When the port is set to IB, the FW implements the Subnet Management Agent (SMA) manage the port. All port attributes can be control remotely by the SM.

Currently, devlink register/unregister is done directly from spectrum/switchx2 port create/remove functions. With a need to introduce a port type change, the devlink port instances have to be persistent across type changes, therefore across port create/remove function calls. So do a bit of reshuffling to achieve that. Signed-off-by:

We recently discovered a bug in the firmware in which a field's length in one of the registers was incorrectly set. This caused the firmware to access garbage data that wasn't initialized by the driver and therefore emit error messages. While the bug is already fixed and the driver usually zeros the buffers passed to the firmware, there are a handful of cases where this isn't done. Zero the buffer in these cases and prevent similar bugs from recurring, as they tend to be hard to debug. Fixes: 52581961 ("mlxsw: core: Implement fan control using hwmon") Signed-off-by:

Currently when calling mlx5_add_flow_rule we accept only one flow destination, this commit allows to pass multiple destinations. This change forces us to change the return structure to a more flexible one. We introduce a flow handle (struct mlx5_flow_handle), it holds internally the number for rules created and holds an array where each cell points the to a flow rule. From the consumers (of mlx5_add_flow_rule) point of view this change is only cosmetic and requires only to change the type of the returned value they store. From the core point of view, we now need to use a loop when allocating and deleting rules (e.g given to us a flow handler). Signed-off-by:

When adding a new rule, if we can match it with compare_match_value and flow tag we might be able to insert the rule to the same fte. In order to do that, there must be an overlap between the actions of the fte and the new rule. When updating the action of an existing fte, we must tell the firmware we are doing so. Signed-off-by:

An fte status becomes FS_FTE_STATUS_EXISTING only after it was created in HW. We can use this in order to simplify the logic on what firmware command to use. If the status isn't FS_FTE_STATUS_EXISTING we need to create the fte, otherwise we need only to update it. Signed-off-by:

TSAR (stands for Transmit Scheduling ARbiter) is a hardware component that is responsible for selecting the next entity to serve on the transmit path. The arbitration defines the QoS policy between the agents connected to the TSAR. The TSAR is a consist two main features: 1) BW Allocation between agents: The TSAR implements a defecit weighted round robin between the agents. Each agent attached to the TSAR is assigned with a weight and it is awarded transmission tokens according to this weight. 2) Rate limer per agent: Each agent attached to the TSAR is (optionally) assigned with a rate limit. TSAR will not allow scheduling for an agent exceeding its defined rate limit. In this patch we implement the API of manipulating the TSAR. Signed-off-by:
