2019-08-26ice: Fix VF configuration issues due to resetAkeem G Abodunrin
This patch fixes a critical reset issue that resulting to the server reboot when an Admin changes VF configuration on the host, for example changing VF to Trusted/non_Trusted mode, the PF driver send reset notification to AVF driver while also continue with reset flow. However, AVF driver schedule another reset due to notification, which causes two concurrent reset going on, and trigger lock up in the FW, with AQ call to delete VSI.

2019-08-26ice: Alloc queue management bitmaps and arrays dynamicallyAnirudh Venkataramanan
The total number of queues available on the device is divided between multiple physical functions (PF) in the firmware and provided to the driver when it gets function capabilities from the firmware. Thus each PF knows how many Tx/Rx queues it has. These queues are then doled out to different VSIs (for LAN traffic, SR-IOV VF traffic, etc.) To track usage of these queues at the PF level, the driver uses two bitmaps avail_txqs and avail_rxqs. At the VSI level (i.e. struct ice_vsi instances) the driver uses two arrays txq_map and rxq_map, to track ownership of VSIs' queues in avail_txqs and avail_rxqs respectively. The aforementioned bitmaps and arrays should be allocated dynamically, because the number of queues supported by a PF is only available once function capabilities have been queried. The current static allocation consumes way more memory than required. This patch removes the DECLARE_BITMAP for avail_txqs and avail_rxqs and instead uses bitmap_zalloc to allocate the bitmaps during init. Similarly txq_map and rxq_map are now allocated in ice_vsi_alloc_arrays. As a result ICE_MAX_TXQS and ICE_MAX_RXQS defines are no longer needed. Also as txq_map and rxq_map are now allocated and freed, some code reordering was required in ice_vsi_rebuild for correct functioning.

2019-08-26ice: add support for enabling/disabling single queuesMaciej Fijalkowski
Refactor the queue handling functions that are going through queue arrays in a way that the logic done for a single queue is pulled out and it will be called for each ring when traversing ring array. This implies that when disabling Tx rings we won't fill up q_ids, q_teids and q_handles arrays. Drop also 'offset' parameter; the value from vsi's txq_map is stored in ring->reg_idx and that drops the need for mentioned parameter. Introduce the ice_vsi_cfg_txq, ice_vsi_stop_tx_ring and ice_vsi_ctrl_rx_ring that are the functions with pulled out logic. There's several Tx queue meta data (q_id, q_handle, q_teid and other) that need to be set up during Tx queue disablement, so let's as well add a helper structure that wraps it up and a function that will be filling it up.

Without this validation we can set vsi->alloc_txq/vsi->alloc_rxq to value smaller than ICE_MAX_BASE_QS_PER_VF and send this command with num_queue_pairs greater than vsi->alloc_txq/vsi->alloc_rxq.

2019-08-26nfp: bpf: fix latency bug when updating stack index registerJiong Wang
NFP is using Local Memory to model stack. LM_addr could be used as base of a 16 32-bit word region of Local Memory. Then, if the stack offset is beyond the current region, the local index needs to be updated. The update needs at least three cycles to take effect, therefore the sequence normally looks like: local_csr_wr[ActLMAddr3, gprB_5] nop nop nop If the local index switch happens on a narrow loads, then the instruction preparing value to zero high 32-bit of the destination register could be counted as one cycle, the sequence then could be something like: local_csr_wr[ActLMAddr3, gprB_5] nop nop immed[gprB_5, 0] However, we have zero extension optimization that zeroing high 32-bit could be eliminated, therefore above IMMED insn won't be available for which case the first sequence needs to be generated.

2019-08-25r8152: Set memory to all 0xFFs on failed reg readsPrashant Malani
get_registers() blindly copies the memory written to by the usb_control_msg() call even if the underlying urb failed. This could lead to junk register values being read by the driver, since some indirect callers of get_registers() ignore the return values. One example is: ocp_read_dword() ignores the return value of generic_ocp_read(), which calls get_registers(). So, emulate PCI "Master Abort" behavior by setting the buffer to all 0xFFs when usb_control_msg() fails. This patch is copied from the r8152 driver (v2.12.0) published by Realtek (www.realtek.com).

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-08-23 This series contains updates to ice driver only. Dave adds logic for the necessary bits to be set in the VSI context for the PF_VSI and the TX_descriptors for control packets egressing the PF_VSI. Updated the logic to detect both DCBx and LLDP states in the firmware engine to account for situations where DCBx is enabled and LLDP is disabled. Fixed the driver to treat the DCBx state of "NOT_STARTED" as a valid state and should not assume "is_fw_lldp" true automatically. Since "enable-fw-lldp" flag was confusing and cumbersome, change the flag to "fw-lldp-agent" with a value of on or off to help clarify whether the LLDP agent is running or not. Brett fixes an issue where synchronize_irq() was being called from the host of VF's, which should not be done. Michal fixed an issue when rebuilding the DCBx configuration while in IEEE mode versus CEE mode, so add a check before copying the configuration value to ensure we are only in CEE mode. Jake fixes the PF to reject any VF request to setup head writeback since the support has been deprecated. Mitch adds an additional check to ensure the VF is active before sending out an error message that a message was unable to be sent to a particular VF. Chinh updates the driver to use "topology" mode when checking the PHY for status, since this mode provides us the current module type that is available. Fixes the driver from clearing the auto_fec_enable bit which was blocking a user from forcing non-spec compliant FEC configurations. Amruth does a refactor on the code to first check, then assign in the virtual channel space. Bruce updates the driver to actually update the stats when a user runs the ethtool command 'ethtool -S <iface>' instead of providing a snapshot of the stats that maybe from a second ago. Akeem fixes up the adding/removing of VSI MAC filters for VFs, so that VFs cannot add/remove a filter from another VSI. We now track the number of filters added right from when the VF resources get allocated and won't get into MAC filter mis-match issue in the switch. ==================== Signed-off-by: David S.

2019-08-23ice: Fix issues updating VSI MAC filtersAkeem G Abodunrin
VSI, especially VF could request to add or remove filter for another VSI, driver should really guide such request and disallow it. However, instead of returning error for such malicious request, driver can simply return success. In addition, we are not tracking number of MAC filters configured per VF correctly - and this leads to issue updating VF MAC filters whenever they were removed and re-configured via bringing VF interface down and up. Also, since VF could send request to update multiple MAC filters at once, driver should program those filters individually in the switch, in order to determine which action resulted to error, and communicate accordingly to the VF. So, with this changes, we now track number of filters added right from when VF resources allocation is done, and could properly add filters for both trusted and non_trusted VFs, without MAC filters mis-match issue in the switch... Also refactor code, so that driver can use new function to add or remove MAC filters.

2019-08-23ice: update ethtool stats on-demandBruce Allan
Users expect ethtool statistics to be updated on-demand when invoking 'ethtool -S <iface>' instead of providing a snapshot of statistics taken once a second (the frequency of the watchdog task where stats are currently updated). Update stats every time 'ethtool -S <iface>' is run. Also, fix an indentation style issue and an unnecessary local variable initialization in ice_get_ethtool_stats() discovered while investigating the subject issue.

2019-08-23ice: reject VF attempts to enable head writebackJacob Keller
The virtchnl interface provides a mechanism for a VF driver to request head writeback support. This feature is deprecated as of AVF 1.0, but older versions of a VF driver may still attempt to request the mode. Since the ice hardware does not support head writeback, we should not accept Tx queue configuration which attempts to enable it. Currently, the driver simply assumes that the headwb_enabled bit will never be set. If a VF driver does request head writeback, the configuration will return successfully, even though head writeback is not enabled. This leaves the VF driver in a non functional state since it is assuming to be operating in head writeback mode. Fix the PF driver to reject any attempt to setup headwb_enabled.

In rebuild DCB desired_dcbx_cfg was copy to local_dcbx_cfg, but if DCBX mode is IEEE desired_dcbx_cfg is not initialized by DCBX config from FW. Change logic to copy config value only if mode is set to CEE. If driver copy desired_dcbx_cfg to local_dcbx_cfg in IEEE mode there is problem with globr. System is frozen after two or more globr.

2019-08-23ice: Account for all states of FW DCBx and LLDPDave Ertman
Currently, only the DCBx status is taken into account to determine if FW LLDP is possible. But there are NVM version coming out with DCBx enabled, and FW LLDP disabled. This is causing errors where the driver sees that DCBx is not disabled, and then tries to register for LLDP MIB change events, and fails.
