2019-05-04ice: Add more validation in ice_vc_cfg_irq_map_msgMichal Swiatkowski
Add few checks to validate msg from iavf driver. Test if we have got enough q_vectors allocated in VSI connected with VF. Add masks for itr_indx and msix_indx to avoid writing to reserved fieldi of QINT. Clear q_vector->num_ring_rx/tx, without it we can increment this value every time we send irq map msg from VF. So after second call this value will be incorrect. Decrement num_vectors from msg, because last vector in iavf msg is misc vector (we don't set map for it).

2019-05-04ice: Don't remove VLAN filters that were never programmedAkeem G Abodunrin
In case of non-trusted VFs, it is possible to program VLAN filter far less than what is requested by the VF originally, thereby makes number of VLAN elements being tracked by VF different from actual VLAN tags. This patch makes sure that we are not attempting to remove VLAN filter that does not exist.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-05-02 This series contains updates to the ice driver only. Anirudh introduces the framework to store queue specific information in the VSI queue contexts. This will allow future changes to update the structure to hold queue specific information. Akeem adds additional check so that if there is no queue to disable when attempting to disable a queue, return a configuration error without acquiring the lock. Fixed an issue with non-trusted VFs being able to add more than the permitted number of VLANs. Bruce removes unreachable code and updated the function to return void since it would never return anything but success. Brett provides most of the changes in the series, starting with reducing the scope of the error variable used and improved the debug message if we fail to configure the receive queue. Updates the driver to use a macro instead of using the same 'for' loop throughout the driver which helps with readability. Fixed an issue where users were led to believe they could set rx-usecs-high value, yet the changes to this value would not stick because it was not yet implemented to allow changes to this value, so implement the missing code to change the value. Found we had unnecessary wait when disabling queues, so remove it. I,proved a wasteful addition operation in our hot path by adding a member to the ice_q_vector structure and the necessary changes to use the member which stores the calculated vector hardware index. Refactored the link event flow to make it cleaner and more clear. Maciej updates the array index when stopping transmit rings, so that process every ring the VSI, not just the rings in a given transmit class. Paul adds support for setting 52 byte RSS hash keys. Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register, since the interrupt handlers will handle resetting the bit, if necessary. Tony adds a missing PHY type, which was causing warning message about an unrecognized PHY. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-05-04net: ena: gcc 8: fix compilation warningSameeh Jubran
GCC 8 contains a number of new warnings as well as enhancements to existing checkers. The warning - Wstringop-truncation - warns for calls to bounded string manipulation functions such as strncat, strncpy, and stpncpy that may either truncate the copied string or leave the destination unchanged. In our case the destination string length (32 bytes) is much shorter than the source string (64 bytes) which causes this warning to show up. In general the destination has to be at least a byte larger than the length of the source string with strncpy for this warning not to showup. This can be easily fixed by using strlcpy instead which already does the truncation to the string.

2019-05-04net: ena: fix: set freed objects to NULL to avoid failing future allocationsSameeh Jubran
In some cases when a queue related allocation fails, successful past allocations are freed but the pointer that pointed to them is not set to NULL. This is a problem for 2 reasons: 1. This is generally a bad practice since this pointer might be accidentally accessed in the future. 2. Future allocations using the same pointer check if the pointer is NULL and fail if it is not. Fixed this by setting such pointers to NULL in the allocation of queue related objects. Also refactored the code of ena_setup_tx_resources() to goto-style error handling to avoid code duplication of resource freeing.

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. The end user experience remains the same, they are using the NVMUpdate tool to update the NVM contents.

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.

Runtime change of PFINT_OICR_ENA register is unnecessary. The handlers should always clear the atomic bit for each task as they start, because it will make sure that any late interrupt will either 1) re-set the bit, or 2) be handled directly in the "already running" task handler.

2019-05-02ice: Fix issue when adding more than allowed VLANsAkeem G Abodunrin
This patch fixes issue with non trusted VFs being able to add more than permitted number of VLANs by adding a check in ice_vc_process_vlan_msg. Also don't return an error in this case as the VF does not need to know that it is not trusted. Also rework ice_vsi_kill_vlan to use the right types.

2019-05-02ice: Remove unnecessary wait when disabling/enabling Rx queuesBrett Creeley
In ice_vsi_ctrl_rx_rings() we are unnecessarily waiting for QRX_CTRL_QENA_REQ and QRX_CTRL_QENA_STAT to be the same value prior to disabling each Rx queue. There is no reason to do this so remove this wait loop as we already have a wait loop after disabling/enabling the Rx queue through the QRX_CTRL register to make sure it gets successfully disabled/enabled.

2019-05-02ice: Add ability to update rx-usecs-highBrett Creeley
Currently the driver allows rx-usecs-high values to be set, but when querying the device for rx-usecs-high the value does not stick. This is because it was not yet implemented. Add code to allow the user to change rx-usecs-high and use this to set the q_vector's intrl value.

2019-05-02ice: Use ice_for_each_q_vector macro where possibleBrett Creeley

2019-05-02ice: Validate ring existence and its q_vector per VSIMaciej Fijalkowski
When stopping Tx rings, we use 'i' as an ring array index for looking up whether the ice_ring exists and have assigned a q_vector. This checks rings only within a given TC and we need to go through every ring in VSI. Use 'q_idx' instead.

2019-05-02ice: Reduce scope of variable in ice_vsi_cfg_rxqsBrett Creeley
