2020-03-05ice: let core reject the unsupported coalescing parametersJakub Kicinski1-56/+3
Set ethtool_ops->supported_coalesce_params to let the core reject unsupported coalescing parameters. This driver correctly rejects all unsupported parameters. As a side effect of these changes the info message about the bad parameter will no longer be printed. We also always reject the tx_coalesce_usecs_high param, even if the target queue pair does not have a TX queue.

2020-02-26iavf: use tc_cls_can_offload_and_chain0() instead of chain checkJiri Pirko1-3/+5
Looks like the iavf code actually experienced a race condition, when a developer took code before the check for chain 0 was put to helper. So use tc_cls_can_offload_and_chain0() helper instead of direct check and move the check to _cb() so this is similar to i40e code.

2020-02-24intel: Replace zero-length array with flexible-array memberGustavo A. R. Silva5-8/+8
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Ben Dooks adds a missing cpu_to_le64() in the e1000e transmit ring flush function. Jia-Ju Bai replaces a couple of udelay() with usleep_range() where we could sleep while holding a spinlock in e1000e. Chen Zhou make 2 functions static in igc, Sasha finishes the legacy power management support in igc by adding resume and schedule suspend requests. Also added register dump functionality in the igc driver. Added device id support for the next generation of i219 devices in e1000e. Fixed a typo in the igc driver that referenced a device that is not support in the driver. Added the missing PTP support when suspending now that igc has legacy power management support. Added PCIe error detection, slot reset and resume capability in igc. Added WoL support for igc as well. Lastly, added a code comment to distinguish between interrupt and flag definitions. Vitaly adds device id support for Tiger Lake platforms, which has another next generation of i219 device in e1000e. ==================== Signed-off-by: David S. Miller <[email protected]>

Avinash adds input validation for software DCB configurations received via lldptool or pcap to ensure bad bandwidth inputs are not inputted which could cause the loss of link. Paul update the malicious driver detection event messages to rate limit once per second and to include the total number of receive|transmit MDD event count.

Brett ensures we clear the relevant values in the QRXFLXP_CNTXT register for VF queues to ensure the receive queue data is not stale. Avinash adds required DCBNL operations for configuring ETS in software DCB CEE mode. Also added code to detect if DCB is in IEEE or CEE mode to properly report what mode we are in. Dave fixes the driver to properly report the current maximum TC, not the maximum allowed number of TCs. Krzysztof adds support for AF_XDP feature in the ice driver. Jake increases the maximum time that the driver will wait for a PR reset to account for possibility of a slightly longer than expected PD reset. Jesse fixes a number of strings which did not have line feeds, so add line feeds so that messages do not rum together, creating a jumbled mess.

Since VF RX MDD events disable the queue, add ethtool private flag mdd-auto-reset-vf to configure VF reset to re-enable the queue.

Fix this by waiting for the VF remove/reset process to happen before checking if the VF is disabled. Also, since many functions for VF administration on the PF were more or less calling the same 3 functions (ice_wait_on_vf_reset(), ice_is_vf_disabled(), and ice_check_vf_init()) move these into the helper function ice_check_vf_ready_for_cfg(). Then call this function in any flow that attempts to configure/query a VF from the PF. Lastly, increase the maximum wait time in ice_wait_on_vf_reset() to 800ms, and modify/add the #define(s) that determine the wait time. This was done for robustness because in rare/stress cases VF removal can take a max of ~800ms and previously the wait was a max of ~300ms.

Remove code that tell the OS that link is going down when user change flow control via ethtool. When link is up it isn't certain that link goes down after 0x0605 aq command. If link doesn't go down, OS thinks that link is down, but physical link is up. To reset this state user have to take interface down and up. If link goes down after 0x0605 command, FW send information about that and after that driver tells the OS that the link goes down. So this code in ethtool is unnecessary.

2020-02-15ice: replace "fallthrough" comments with fallthrough reserved wordBruce Allan5-9/+9
"fallthrough" comments are used in switch case statements to explicitly indicate the code is intended to fall through to the following statement. Different variants of "fallthough" are acceptable, e.g. "fall through", "fallthrough", "Fall-through". The GCC compiler has an optional warning (-Wimplicit-fallthrough[=n]) to warn when such a comment is not present; the default version of which is enabled when compiling the Linux kernel. There have been recent discussions in kernel mailing lists regarding replacing non-standardized "fallthrough" comments with the pseudo-reserved word 'fallthrough' which will be defined as __attribute__ ((fallthrough)) for versions of gcc that support it (i.e. gcc 7 and newer) or as a nop for versions that do not.

2020-02-15ice: Fix virtchnl_queue_select bitmap validationBrett Creeley1-8/+18
Currently in ice_vc_ena_qs_msg() we are incorrectly validating the virtchnl queue select bitmaps. The virtchnl_queue_select rx_queues and tx_queue bitmap is being compared against ICE_MAX_BASE_QS_PER_VF, but the problem is that these bitmaps can have a value greater than ICE_MAX_BASE_QS_PER_VF. Fix this by comparing the bitmaps against BIT(ICE_MAX_BASE_QS_PER_VF). Also, add the function ice_vc_validate_vqs_bitmaps() that checks to see if both virtchnl_queue_select bitmaps are empty along with checking that the bitmaps only have valid bits set. This function can then be used in both the queue enable and disable flows.

This is causing issues where the Rx queue disable times out with LFC enabled. This can be improved by detecting when the VF is trying to disable all of its queues. Also remove the variable num_qs_ena from the ice_vf structure as it was only used to see if there were no Rx and no Tx queues active. Instead add a function that checks if both the vf->rxq_ena and vf->txq_ena bitmaps are empty.

2020-02-15ice: Handle LAN overflow event for VF queuesBrett Creeley5-0/+86
Currently we are not handling LAN overflow events. There can be cases where LAN overflow events occur on VF queues, especially with Link Flow Control (LFC) enabled on the controlling PF. In order to recover from the LAN overflow event caused by a VF we need to determine if the queue belongs to a VF and reset that VF accordingly. The struct ice_aqc_event_lan_overflow returns a copy of the GLDCB_RTCTQ register, which tells us what the queue index is in the global/device space. The global queue index needs to first be converted to a PF space queue index and then it can be used to find if a VF owns it.

2020-02-15ice: Fix implicit queue mapping mode in ice_vsi_get_qsBrett Creeley1-9/+12
Currently in ice_vsi_get_qs() we set the mapping_mode for Tx and Rx to vsi->[tx|rx]_mapping_mode, but the problem is vsi->[tx|rx]_mapping_mode have not been set yet. This was working because ICE_VSI_MAP_CONTIG is defined to 0. Fix this by being explicit with our mapping mode by initializing the Tx and Rx structure's mapping_mode to ICE_VSI_MAP_CONTIG and then setting the vsi->[tx|rx]_mapping_mode to the [tx|rx]_qs_cfg.mapping_mode values. Also, only assign the vsi->[tx|rx]_mapping_mode when the queues are successfully mapped to the VSI. With this change there was no longer a need to initialize the ret variable to 0 so remove that.

2020-02-15ice: Add support to enable/disable all Rx queues before waitingBrett Creeley8-34/+67
Currently when we enable/disable all Rx queues we do the following sequence for each Rx queue and then move to the next queue. 1. Enable/Disable the Rx queue via register write. 2. Read the configuration register to determine if the Rx queue was enabled/disabled successfully. In some cases enabling/disabling queue 0 fails because of step 2 above. Fix this by doing step 1 for all of the Rx queues and then step 2 for all of the Rx queues. Also, there are cases where we enable/disable a single queue (i.e. SR-IOV and XDP) so add a new function that does step 1 and 2 above with a read flush in between. This change also required a single Rx queue to be enabled/disabled with and without waiting for the change to propagate through hardware. Fix this by adding a boolean wait flag to the necessary functions. Also, add the keywords "one" and "all" to distinguish between enabling/disabling a single Rx queue and all Rx queues respectively.

2020-02-15ice: Only allow tagged bcast/mcast traffic for VF in port VLANBrett Creeley1-18/+31
Currently the VF can see other's broadcast and multicast traffic because it always has a VLAN filter for VLAN 0. Fix this by removing/adding the VF's VLAN 0 filter when a port VLAN is added/removed respectively. This required a few changes. 1. Move where we add VLAN 0 by default for the VF into ice_alloc_vsi_res() because this is when we determine if a port VLAN is present for load and reset. 2. Moved where we kill the old port VLAN filter in ice_set_vf_port_vlan() to the very end of the function because it allows us to save the old port VLAN configuration upon any failure case. 3. During adding/removing of a port VLAN via ice_set_vf_port_vlan() we also need to remove/add the VLAN 0 filter rule respectively. 4. Improve log messages.

2020-02-15ice: Fix Port VLAN priority bitsBrett Creeley2-19/+13
Currently when configuring a port VLAN for a VF we are only shifting the QoS bits by 12. This is incorrect. Fix this by getting rid of the ICE specific VLAN defines and use the kernel VLAN defines instead. Also, don't assign a value to vlanprio until the VLAN ID and QoS parameters have been validated. Also, there are many places we do (le16_to_cpu(vsi->info.pvid) & VLAN_VID_MASK). Instead do (vf->port_vlan_info & VLAN_VID_MASK) because we always save what's stored in vsi->info.pvid to vf->port_vlan_info in the CPU's endianness.

2020-02-15ice: Refactor port vlan configuration for the VFBrett Creeley2-51/+37
Currently ice_vsi_manage_pvid() calls ice_vsi_[set|kill]_pvid_fill_ctxt() when enabling/disabling a port VLAN on a VSI respectively. These two functions have some duplication so just move their unique pieces inline in ice_vsi_manage_pvid() and then the duplicate code can be reused for both the enabling/disabling paths. Before this patch the info.pvid field was not being written correctly via ice_vsi_kill_pvid_fill_ctxt() so it was being hard coded to 0 in ice_set_vf_port_vlan(). Fix this by setting the info.pvid field to 0 before calling ice_vsi_update() in ice_vsi_manage_pvid(). We currently use vf->port_vlan_id to keep track of the port VLAN ID and QoS, which is a bit misleading. Fix this by renaming it to vf->port_vlan_info. Also change the name of the argument for ice_vsi_manage_pvid() from vid to pvid_info. In ice_vsi_manage_pvid() only save the fields that were modified in the VSI properties structure on success instead of the entire thing.
