* | | ice: Check for actual link state of port after resetDave Ertman2018-10-023-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are currently replaying the link state of a port after a reset, but it is possible that the link state of a port can change during the reset process. So check for the current link state of a port during the rebuild process of a reset.

* | | ice: Implement VSI replay frameworkAnirudh Venkataramanan2018-10-026-51/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, switch filters get replayed after reset. In addition to filters, other VSI attributes (like RSS configuration, Tx scheduler configuration, etc.) also need to be replayed after reset. Thus, instead of replaying based on functional blocks (i.e. replay all filters for all VSIs, followed by RSS configuration replay for all VSIs, and so on), it makes more sense to have the replay centered around a VSI. In other words, replay all configurations for a VSI before moving on to rebuilding the next VSI. To that effect, this patch introduces a VSI replay framework in a new function ice_vsi_replay_all. Currently it only replays switch filters, but it will be expanded in the future to replay additional VSI attributes.

* | | ice: Expand use of VSI handles part 1/2Anirudh Venkataramanan2018-10-024-200/+328
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A VSI handle is just a number the driver maintains to uniquely identify a VSI. A VSI handle is backed by a VSI number in the hardware. When interacting when the hardware, VSI handles are converted into VSI numbers. In commit 0f9d5027a749 ("ice: Refactor VSI allocation, deletion and rebuild flow"), VSI handles were introduced but it was used only when creating and deleting VSIs. This patch is part one of two patches that expands the use of VSI handles across the rest of the driver. Also in this patch, certain parts of the code had to be refactored to correctly use VSI handles.

* | | ice: Change pf state behavior to protect reset pathDave Ertman2018-10-014-30/+31

If the reset is originated by the driver, then the relevant one of the following bits will be set when the reset is scheduled: __ICE_PFR_REQ __ICE_CORER_REQ __ICE_GLOBR_REQ This bit will not be cleared until after the rebuild has completed. If the reset is originated by the FW, then the first the driver knows of it will be the reception of the OICR interrupt. The __ICE_RESET_OICR_RECV bit will be set in the interrupt handler. This will also be the indicator in a SW originated reset that we have completed the pre-OICR tasks and have informed the FW that a reset was requested. To utilize these bits, change the function: ice_is_reset_recovery_pending() to be: ice_is_reset_in_progress() The new function will check all of the above bits in the pf->state and will return a true if one or more of these bits are set.

* | | ice: fix changing of ring descriptor size (ethtool -G)Bruce Allan2018-09-282-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rx_mini_pending was set to an incorrect value. This was causing EINVAL to always be returned to 'ethtool -G'. The driver does not support mini or jumbo rings so the respective settings should be zero. Also, change the valid range of the number of descriptors in the rings to make the code simpler and easier for users to understand (this removes the valid settings of 8 and 16). Add a system log message indicating when the number is rounded-up from what the user specifies with the 'ethtool -G' command (i.e. when it is not a multiple of 32), and update the log message when a user-provided value is out of range to also indicate the stride.

* | | ice: update fw version check logicJacob Keller2018-09-281-11/+19

This is currently tested by comparing each field separately. Thus, we compare the branch field against the MAX_FW_API_VER_BRANCH, and so forth. This means that currently, if we suppose that the max firmware version is defined as 0.2.1, i.e. Then firmware 0.1.3 will fail to load. This is because the minor version 3 is greater than the max minor version 1. This is not intuitive, because of the notion that increasing the major firmware version to 2 should mean any firmware version with a major version is less than 2 should be considered older than 2... In order to allow both 0.2.1 and 0.1.3 to load, you would have to define the "max" firmware version as 0.2.3.. It is possible that such a firmware version doesn't even exist yet! Fix this by replacing the current logic with an updated check that behaves as follows: First, we check the major version. If it is greater than the expected version, then we prevent driver load. Additionally, a warning message is logged to indicate to the system administrator that they need to update their driver. This is now the only case where the driver will refuse to load. Second, if the major version is less than the expected version, we log an information message indicating the NVM should be updated. Third, if the major version is exact, we'll then check the minor version. If the minor version is more than two versions less than expected, we log an information message indicating the NVM should be updated. If it is more than two versions greater than the expected version, we log an information message that the driver should be updated. To support this, the ice_aq_ver_check function needs its signature updated to pass the HW structure. Since we now pass this structure, there is no need to pass the firmware API versions separately.

This is important, as it prevents attempts to access the lock of an already shutdown queue. Unfortunately, we checked rq.head and sq.head as the value to determine if the queue was initialized. This doesn't work, because head is not reset when the queue is shutdown. In some flows, the adminq will have already been shut down prior to calling ice_shutdown_all_ctrlqs. This can result in a crash due to attempting to access the already destroyed mutex. Fix this by using rq.count and sq.count instead. Indeed, ice_shutdown_sq and ice_shutdown_rq already indicate that this is the value we should be using to determine of the queue was initialized.

Mariusz fixes an issue where the VF link state was not being updated properly when the PF is down or up. Also cleaned up the promiscuous configuration during a VF reset. Patryk simplifies the code a bit to use the variables for PF and HW that are declared, rather than using the VSI pointers. Cleaned up the message length parameter to several virtchnl functions, since it was not being used (or needed). Harshitha fixes two potential race conditions when trying to change VF settings by creating a helper function to validate that the VF is enabled and that the VSI is set up. Sergey corrects a double "link down" message by putting in a check for whether or not the link is up or going down. Björn addresses an AF_XDP zero-copy issue that buffers passed from userspace to the kernel was leaked when the hardware descriptor ring was torn down. A zero-copy capable driver picks buffers off the fill ring and places them on the hardware receive ring to be completed at a later point when DMA is complete. Similar on the transmit side; The driver picks buffers off the transmit ring and places them on the transmit hardware ring. In the typical flow, the receive buffer will be placed onto an receive ring (completed to the user), and the transmit buffer will be placed on the completion ring to notify the user that the transfer is done. However, if the driver needs to tear down the hardware rings for some reason (interface goes down, reconfiguration and such), the userspace buffers cannot be leaked. They have to be reused or completed back to userspace. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up promiscuous configuration when a VF reset occurs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As diagnosed by Song Liu, ndo_poll_controller() can be very dangerous on loaded hosts, since the cpu calling ndo_poll_controller() might steal all NAPI contexts (for all RX/TX queues of the NIC). This capture can last for unlimited amount of time, since one cpu is generally not able to drain all the queues under load. i40evf uses NAPI for TX completions, so we better let core networking stack call the napi->poll() to avoid the capture.
