ixgbevf: Mailbox improvements Improve reliability of the mailbox communication and remove its potential flaws that may lead to the undefined or faulty behavior. Recently some users reported issues on ESX with 10G Intel NICs which were found to be caused by incorrect implementation of the PF-VF mailbox communication. Technical investigation highlighted areas to improve in the communication between PF or VF that wants to send the message (sender) and the other part which receives the message (receiver): - Locking the mailbox when the sender wants to send a message - Releasing the mailbox when the communication ends - Returning the result of the mailbox message execution Signed-off-by: Radoslaw Tyl <radoslawx.tyl@intel.com> Tested-by: Tony Brelinski <tony.brelinski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

locking/atomics: COCCINELLE/treewide: Convert trivial ACCESS_ONCE() patterns to READ_ONCE()/WRITE_ONCE() Please do not apply this to mainline directly, instead please re-run the coccinelle script shown below and apply its output. For several reasons, it is desirable to use {READ,WRITE}_ONCE() in preference to ACCESS_ONCE(), and new code is expected to use one of the former. So far, there's been no reason to change most existing uses of ACCESS_ONCE(), as these aren't harmful, and changing them results in churn. However, for some features, the read/write distinction is critical to correct operation. To distinguish these cases, separate read/write accessors must be used. This patch migrates (most) remaining ACCESS_ONCE() instances to {READ,WRITE}_ONCE(), using the following coccinelle script: ---- // Convert trivial ACCESS_ONCE() uses to equivalent READ_ONCE() and // WRITE_ONCE() // $ make coccicheck COCCI=/home/mark/once.cocci SPFLAGS="--include-headers" MODE=patch virtual patch @ depends on patch @ expression E1, E2; @@ - ACCESS_ONCE(E1) = E2 + WRITE_ONCE(E1, E2) @ depends on patch @ expression E; @@ - ACCESS_ONCE(E) + READ_ONCE(E) ---- Signed-off-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Paul E.

ixgbevf: Add range checking for setting MTU Currently when setting the VF's MTU, the PF can return a NACK but this isn't passed on to the VF. Propagate the results from the PF to the VF so errors can be reported. In ixgbevf_change_mtu, return an error and reject the change. For ixgbevf_configure_rx, log the error for debugging purposes since the function is buried in a series of Rx config routines that are void.

By doing this we can avoid having to pull too much information out of the lower layers and can instead just make use of the mac_ops pointers since they should differ between the two types of VFs anyway.

ixgbe, ixgbevf: Add new mbox API xcast mode The limitation of the number of multicast address for VF is not enough for the large scale server with SR-IOV feature. IPv6 requires the multicast MAC address for each IP address to handle the Neighbor Solicitation message. We couldn't assign over 30 IPv6 addresses to a single VF. This patch introduces the new mailbox API, IXGBE_VF_UPDATE_XCAST_MODE, to update multicast mode of VF. This adds 3 modes; - NONE only L2 exact match addresses or Flow Director enabled - MULTI BAM and ROMPE set - ALLMULTI BAM, ROMPE and MPE set If a guest VF user wants over 30 MAC multicast addresses, set IFF_ALLMULTI to request PF to update xcast mode to enable VF multicast promiscuous mode. On the other hand, enabling VF multicast promiscuous mode may affect security and performance in the network of the NIC. Only trusted VF can enable multicast promiscuous mode. The behavior of untrusted VF is the same as previous version.
