2019-06-14i40e: remove duplicate stat calculation for tx_errorsJacob Keller
The tx_errors statistic was being calculated twice in i40e_update_eth_stats. This appears to be as of commit 201db2898f2c ("i40e: add missing VSI statistics", 2014-03-25). Remove the extra i40e_stat_update32 call for GLV_TEPC.

2019-06-14i40e: Check if the BAR size is large enough before writing to registersAdam Ludkiewicz
This patch fixes the problem with a kernel panic occurring when trying to bind the i40e driver to a non-i40e port. The problem is fixed by checking if the BAR size in the device is large enough by reading the highest register.

2019-06-14i40e: add input validation for virtchnl handlersSergey Nemov
Change some data to unsigned int instead of integer when we compare. Check LUT values in VIRTCHNL_OP_CONFIG_RSS_LUT handler. Also enhance error/warning messages to print the real values of I40E_MAX_VF_QUEUES, I40E_MAX_VF_VSI and I40E_DEFAULT_QUEUES_PER_VF instead of plain text. Refactor code to comply with 'check first then assign' policy. Remove duplicate checks for VIRTCHNL_OP_CONFIG_RSS_KEY and VIRTCHNL_OP_CONFIG_RSS_LUT opcodes in i40e_vc_process_vf_msg(). We have the very same checks inside the handlers already.

2019-06-14i40e: Improve AQ log granularityDoug Dziggel
This patch makes it possible to log only AQ descriptors, without the entire AQ message buffers being dumped too. It should greatly reduce kernel log size in cases where a full AQ dump is not needed. Selection is made by setting flags in hw->debug_mask. Additionally, some debug messages that preceded an AQ dump have been moved to I40E_DEBUG_AQ_COMMAND class, which seems more appropriate.

2019-05-04i40e: Use struct_size() in kzalloc()Gustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL) Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL) Notice that, in this case, variable size is not necessary, hence it is removed.

2019-05-03i40e: Introduce recovery mode supportAlice Michael
This patch introduces "recovery mode" to the i40e driver. It is part of a new Any2Any idea of upgrading the firmware. In this approach, it is required for the driver to have support for "transition firmware", that is used for migrating from structured to flat firmware image. In this new, very basic mode, i40e driver must be able to handle particular IOCTL calls from the NVM Update Tool and run a small set of AQ commands. These additional AQ commands are part of the interface used by the NVMUpdate tool. The NVMUpdate tool contains all of the necessary logic to reference these new AQ commands.

2019-05-03i40e: fix misleading message about promisc setting on un-trusted VFHarshitha Ramamurthy
A refactor of the i40e_vc_config_promiscuous_mode_msg function moved the check for un-trusted VF into another function. We have to lie to an un-trusted VF that its request to set promiscuous mode is successful even when it is not because we don't want the VF to find out its trust status this way. With the refactor, we were running into a case where even though we were not setting promiscuous mode for an un-trusted VF, we still printed a misleading message that it was successful.

2019-05-03i40e: remove out-of-range comparisons in i40e_validate_cloud_filterJacob Keller
The function i40e_validate_cloud_filter checks that the destination and source port numbers are valid by attempting to ensure that the number is non-zero and no larger than 0xFFFF. However, the types for the dst_port and src_port variable are __be16 which by definition cannot be larger than 0xFFFF Since these values cannot be larger than 2 bytes, the check to see if they exceed 0xFFFF is meaningless. One might consider these checks as some sort of defensive coding, in case the type was later changed. However, these checks also byte-swap the value before comparison using be16_to_cpu, which will truncate the values to 16bits anyways. Additionally, changing the type would require updating the opcodes to support new data layout of these virtchnl commands. Remove the check to silence the -Wtype-limits warning that was added to GCC 8.

2019-04-16i40e: Able to add up to 16 MAC filters on an untrusted VFAdam Ludkiewicz
This patch fixes the problem with the driver being able to add only 7 multicast MAC address filters instead of 16. The problem is fixed by changing the maximum number of MAC address filters to 16+1+1 (two extra are needed because the driver uses 1 for unicast MAC address and 1 for broadcast).

2019-04-16i40e: Fix for 10G ports LED not blinkingPiotr Marczak
On some hardware LEDs would not blink after command 'ethtool -p {eth-port}' in certain circumstances. Now, function does not care about the activity of the LED (though still preserves its state) but forcibly executes identification blinking and then restores the LED state.

2019-04-16i40e: save PTP time before a device resetJacob Keller
In the case where PTP is running on the hardware clock, but the kernel system time is not being synced, a device reset can mess up the clock time. This occurs because we reset the clock time based on the kernel time every reset. This causes us to potentially completely reset the PTP time, and can cause unexpected behavior in programs like ptp4l. Avoid this by saving the PTP time prior to device reset, and then restoring using that time after the reset. Directly restoring the PTP time we saved isn't perfect, because time should have continued running, but the clock will essentially be stopped during the reset. This is still better than the current solution of assuming that the PTP HW clock is synced to the CLOCK_REALTIME. We can do even better, by saving the ktime and calculating a differential, using ktime_get(). This is based on CLOCK_MONOTONIC, and allows us to get a fairly precise measure of the time difference between saving and restoring the time. Using this, we can update the saved PTP time, and use that as the value to write to the hardware clock registers. This, of course is not perfect. However, it does help ensure that the PTP time is restored as close as feasible to the time it should have been if the reset had not occurred. During device initialization, continue using the system time as the source for the creation of the PTP clock, since this is the best known current time source at driver load.

2019-04-16i40e: Implement DDP support in i40e driverAleksandr Loktionov
This patch introduces DDP (Dynamic Device Personalization) which allows loading profiles that change the way internal parser interprets processed frames. To load DDP profiles it utilizes ethtool flash feature. The files with recipes must be located in /var/lib/firmware directory. Afterwards the recipe can be loaded by invoking: ethtool -f <if_name> <file_name> 100 ethtool -f <if_name> - 100 See further details of this feature in the i40e documentation, or visit https://www.intel.com/content/www/us/en/architecture-and-technology/ethernet/dynamic-device-personalization-brief.html The driver shall verify DDP profile can be loaded in accordance with the rules: * Package with Group ID 0 are exclusive and can only be loaded the first. * Packages with Group ID 0x01-0xFE can only be loaded simultaneously with the packages from the same group. * Packages with Group ID 0xFF are compatible with all other packages.
