Introduce ixgbe_link_operations struct with the following changes: read_i2c_combined => read_link read_i2c_combined_unlocked => read_link_unlocked write_i2c_combined => write_link write_i2c_combined_unlocked => write_link_unlocked This will allow X550EM_a to override these methods for MDIO access while X550EM_x provides methods to use I2C combined access. This also adds a new structure, ixgbe_link_info, to hold information about the link. Initially this is just method pointers and a bus address. The functions involved in combined I2C accesses were moved from ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry out the combined I2C accesses were left in ixgbe_phy.c because they share some functions with other I2C methods. v2 - set hw->link.ops in probe. v3 - check ii->link_ops before setting it since we don't have it for all devices.

Jakub Kicinski says: ==================== ring reconfiguration and XDP support This set adds support for ethtool channel API and XDP. I kick off with ethtool get_channels() implementation. set_channels() needs some preparations to get right. I follow the prepare/commit paradigm and allocate all resources before stopping the device. It has already been done for ndo_change_mtu and ethtool set_ringparam(), it makes sense now to consolidate all the required logic in one place. XDP support requires splitting TX rings into two classes - for the stack and for XDP. The ring structures are identical. The differences are in how they are connected to IRQ vector structs and how the completion/cleanup works. When XDP is enabled I switch from the frag allocator to page-per-packet and map buffers BIDIRECTIONALly. Last but not least XDP offload is added (the patch just takes care of the small formal differences between cls_bpf and XDP). There is a tiny & trivial DebugFS patch in the mix, I hope it can be taken via net-next provided we have the right Acks. Resending with improved commit message and CCing more people on patch 10. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Lendacky, Thomas authored
Currently, the Rx and Tx fifos are evenly allocated between the hardware queues of the device. As more queues are instantiated, the fifo memory needs to be able to be allocated based on queue priority. This allows for higher priority queues to have more fifo memory than lower priority queues. Prepare for this by modifying the current fifo calculation to assign the fifo queue allocation in an array that is then used to program the hardware. Signed-off-by:

Lorenzo Colitti says: ==================== net: inet: Support UID-based routing This patchset adds support for per-UID routing. It allows the administrator to configure rules such as: ip rule add uidrange 100-200 lookup 123 This functionality has been in use by all Android devices since 5.0. It is primarily used to impose per-app routing policies (on Android, every app has its own UID) without having to resort to rerouting packets in iptables, which breaks getsockname() and MTU/MSS calculation, and generally disrupts end-to-end connectivity. This patch series is similar to the code currently used on Android, but has better correctness and performance because it stores the UID in the socket instead of calling sock_i_uid. This avoids contention on sk->sk_callback_lock, and makes it possible to correctly route a socket on which userspace has called close(), for which sock_i_uid will return 0. Changes from v1: - Don't set the UID in sk_clone_lock, it's already set by sock_copy. - For packets originated by kernel sockets, don't use the socket UID. This is the UID that created the namespace, but it might not be mapped in the namespace at all. Instead, use UID 0 in the namespace, which is less surprising and consistent with what happens in the root namespace. - Fix UID routing of IPv4 and IPv6 SYN_RECV sockets. - Fix UID routing of received IPv6 redirects. ==================== Signed-off-by: -

- Use the UID in routing lookups made by protocol connect() and sendmsg() functions. - Make sure that routing lookups triggered by incoming packets (e.g., Path MTU discovery) take the UID of the socket into account. - For packets not associated with a userspace socket, (e.g., ping replies) use UID 0 inside the user namespace corresponding to the network namespace the socket belongs to. This allows all namespaces to apply routing and iptables rules to kernel-originated traffic in that namespaces by matching UID 0. This is better than using the UID of the kernel socket that is sending the traffic, because the UID of kernel sockets created at namespace creation time (e.g., the per-processor ICMP and TCP sockets) is the UID of the user that created the socket, which might not be mapped in the namespace.

Protocol sockets (struct sock) don't have UIDs, but most of the time, they map 1:1 to userspace sockets (struct socket) which do. Various operations such as the iptables xt_owner match need access to the "UID of a socket", and do so by following the backpointer to the struct socket. This involves taking sk_callback_lock and doesn't work when there is no socket because userspace has already called close(). Simplify this by adding a sk_uid field to struct sock whose value matches the UID of the corresponding struct socket. The semantics are as follows: 1. Whenever sk_socket is non-null: sk_uid is the same as the UID in sk_socket, i.e., matches the return value of sock_i_uid. Specifically, the UID is set when userspace calls socket(), fchown(), or accept(). 2. When sk_socket is NULL, sk_uid is defined as follows: - For a socket that no longer has a sk_socket because userspace has called close(): the previous UID. - For a cloned socket (e.g., an incoming connection that is established but on which userspace has not yet called accept): the UID of the socket it was cloned from. - For a socket that has never had an sk_socket: UID 0 inside the user namespace corresponding to the network namespace the socket belongs to. Kernel sockets created by sock_create_kern are a special case of #1 and sk_uid is the user that created them. For kernel sockets created at network namespace creation time, such as the per-processor ICMP and TCP sockets, this is the user that created the network namespace. Signed-off-by: -

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: refine port operations The Marvell chips have one internal SMI device per port, containing a set of registers used to configure a port's link, STP state, default VLAN or addresses database, etc. This patchset creates port files to implement the port operations as described in datasheets, and extend the chip ops structure with them. Patches 1 to 6 implement accessors for port's STP state, port based VLAN map, default FID, default VID, and 802.1Q mode. Patches 7 to 11 implement the port's MAC setup of link state, duplex mode, RGMII delay and speed, all accessed through port's register 0x01. The new port's MAC setup code is used to re-implement the adjust_link code and correctly force the link down before changing any of the MAC settings, as requested by the datasheets. The port's MAC accessors use values compatible with struct phy_device (e.g. DUPLEX_FULL) and extend them when needed (e.g. SPEED_MAX). Changes in v2: - Strictly use new _UNFORCED values instead of re-using _UNKNOWN ones. ==================== Signed-off-by: -

Now that we have setters to configure the port's MAC, use them to refactor the port setup and adjust_link code. Note that port's MAC speed, duplex or RGMII delay must not be changed unless the port's link is forced down. So wrap all that in a mv88e6xxx_port_setup_mac function. Signed-off-by:
