Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2018-03-23 This series contains updates to ixgbe and ixgbevf only. Paul adds status register reads to reduce a potential race condition where registers can read 0xFFFFFFFF during a PCI reset, which in turn causes the driver to remove the adapter. Then fixes an assignment operation with an "OR" operation. Shannon Nelson provides several IPsec offload cleanups to ixgbe, as well as a patch to enable TSO with IPsec offload. Tony provides the much anticipated XDP support for ixgbevf. Currently, pass, drop and XDP_TX actions are supported, as well as meta data and stats reporting. Björn Töpel tweaks the page counting for XDP_REDIRECT, since a page can have its reference count decreased via the xdp_do_redirect() call. ==================== Signed-off-by:David S.

In net commit 8175f7c4736f ("mlxsw: spectrum: Prevent duplicate mirrors") we prevented the user from mirroring more than once from a single binding point (port-direction pair). The fix was essentially reverted in a merge conflict resolution when net was merged into net-next. Restore it.

The current page counting scheme assumes that the reference count cannot decrease until the received frame is sent to the upper layers of the networking stack. This assumption does not hold for the XDP_REDIRECT action, since a page (pointed out by xdp_buff) can have its reference count decreased via the xdp_do_redirect call. To work around that, we now start off by a large page count and then don't allow a refcount less than two. Signed-off-by:

XDP stats are included in TX stats, however, they are not reported in TX queue stats since they are setup on different queues. Add reporting for XDP queue stats to provide consistency between the total stats and per queue stats. Signed-off-by:

This implements the XDP_TX action which is modeled on the ixgbe implementation. However instead of using CPU id to determine which XDP queue to use, this uses the received RX queue index, which is similar to i40e. Doing this eliminates the restriction that number of CPUs not exceed number of XDP queues that ixgbe has. Also, based on the number of queues available, the number of TX queues may be reduced when an XDP program is loaded in order to accommodate the XDP queues.

Replaced an assignment operation with an OR operation. The variable assignment was overwriting the value read from the PHY register. The OR operation sets only the intended register bits. The bits that were being overwritten are reserved, so the assignment had no functional impact. Reported by: Shannon Nelson <shannon.nelson@oracle.com> Signed-off-by:

Add status register reads and delay between reads to ixgbe_check_remove. Registers can read 0xFFFFFFFF during PCI reset, which causes the driver to remove the adapter. The additional status register reads can reduce the chance of this race condition. If the status register is not 0xFFFFFFFF, then ixgbe_check_remove returns the value of the register being read.

Jon Maloy says: ==================== tipc: introduce 128-bit auto-configurable node id We introduce a 128-bit free-format node identity as an alternative to the legacy <Zone.Cluster.Node> structured 32-bit node address. We also make configuration of this identity optional; if a bearer is enabled without a pre-configured node id it will be set automatically based on the used interface's MAC or IP address. ==================== Signed-off-by: -
Jon Maloy authored
Selecting and explicitly configuring a TIPC node identity may be unwanted in some cases. In this commit we introduce a default setting if the identity has not been set at the moment the first bearer is enabled. We do this by using a raw copy of a unique identifier from the used interface: MAC address in the case of an L2 bearer, IPv4/IPv6 address in the case of a UDP bearer. Acked-by:

When a 32-bit node address is generated from a 128-bit identifier, there is a risk of collisions which must be discovered and handled. We do this as follows: - We don't apply the generated address immediately to the node, but do instead initiate a 1 sec trial period to allow other cluster members to discover and handle such collisions. - During the trial period the node periodically sends out a new type of message, DSC_TRIAL_MSG, using broadcast or emulated broadcast, to all the other nodes in the cluster. - When a node is receiving such a message, it must check that the presented 32-bit identifier either is unused, or was used by the very same peer in a previous session. In both cases it accepts the request by not responding to it. - If it finds that the same node has been up before using a different address, it responds with a DSC_TRIAL_FAIL_MSG containing that address. - If it finds that the address has already been taken by some other node, it generates a new, unused address and returns it to the requester. - During the trial period the requesting node must always be prepared to accept a failure message, i.e., a message where a peer suggests a different (or equal) address to the one tried. In those cases it must apply the suggested value as trial address and restart the trial period. This algorithm ensures that in the vast majority of cases a node will have the same address before and after a reboot. If a legacy user configures the address explicitly, there will be no trial period and messages, so this protocol addition is completely backwards compatible. Acked-by:

We add a 128-bit node identity, as an alternative to the currently used 32-bit node address. For the sake of compatibility and to minimize message header changes we retain the existing 32-bit address field. When not set explicitly by the user, this field will be filled with a hash value generated from the much longer node identity, and be used as a shorthand value for the latter. We permit either the address or the identity to be set by configuration, but not both, so when the address value is set by a legacy user the corresponding 128-bit node identity is generated based on the that value.
