Shay Agroskin says: ==================== XDP Redirect implementation for ENA driver ENA is adding XDP Redirect support for its driver and some other small tweaks. This series adds the following: - Make log messages in the driver have a uniform format using netdev_* function - Improve code readability - Add support for XDP Redirect ==================== Link: https://lore.kernel.org/r/20201208180208.26111-1-shayagr@amazon.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-12-09net: ena: introduce ndo_xdp_xmit() function for XDP_REDIRECTShay Agroskin
This patch implements the ndo_xdp_xmit() net_device function which is called when a packet is redirected to this driver using an XDP_REDIRECT directive. The function receives an array of xdp frames that it needs to xmit. The TX queues that are used to xmit these frames are the XDP queues used by the XDP_TX flow. Therefore a lock is added to synchronize both flows (XDP_TX and XDP_REDIRECT). Signed-off-by: Shay Agroskin <shayagr@amazon.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-12-09net: ena: use xdp_return_frame() to free xdp framesShay Agroskin
XDP subsystem has a function to free XDP frames and their associated pages. Using this function would help the driver's XDP implementation to adjust to new changes in the XDP subsystem in the kernel (e.g. introduction of XDP MB). Also, remove 'xdp_rx_page' field from ena_tx_buffer struct since it is no longer used. Signed-off-by: Shay Agroskin <shayagr@amazon.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2020-12-09net: ena: introduce XDP redirect implementationShay Agroskin
This patch adds a partial support for the XDP_REDIRECT directive which instructs the driver to pass the packet to an interface specified by the program. The directive is passed to the driver by calling bpf_redirect() or bpf_redirect_map() functions from the eBPF program. To lay the ground for integration with the existing XDP TX implementation the patch removes the redundant page ref count increase in ena_xdp_xmit_frame() and then decrease in ena_clean_rx_irq(). Instead it only DMA unmaps descriptors for which XDP TX or REDIRECT directive was received. The XDP Redirect support is still missing .ndo_xdp_xmit function implementation, which allows to redirect packet to an ENA interface, which would be added in a later patch.

Rename the ena_xdp_xmit_buff() function to ena_xdp_xmit_frame() and pass it an xdp_frame struct instead of xdp_buff. This change lays the ground for XDP redirect implementation which uses xdp_frames when 'xmit'ing packets.

2020-12-09net: ena: aggregate stats increase into a functionShay Agroskin
Introduce ena_increase_stat() function to increase statistics by a certain number. The function includes the - lock aquire (on 32bit machines) - stat increase - lock release (on 32bit machines) line sequence that is ubiquitous across the driver. The function increases a single stat at a time and several stats which are increased together weren't put into a function to avoid calling the function several times for each stat which looks bad and might decrease performance.

2020-12-09net: ena: add device distinct log prefix to filesShay Agroskin
ENA logs are adjusted to display the full ENA representation to distinct each ENA device in case of multiple interfaces. Using netdev_err/warn and dev_info functions for logging provides uniform printing with clear distinction of the device and interface. This patch changes all printing in ena_com files to use netev_* logging functions except for messages of info level. Log functions of that level would be printed with dev_info because of the early stage they are called in when net_device struct isn't yet registered. To allow using netdev_* functions in all ena_com functions, a pointer to the net_device was added to ena_com_dev struct. The patch also adds some log messages to make driver debugging easier.

2020-12-09net: ena: use constant value for net_device allocationShay Agroskin
The patch changes the maximum number of RX/TX queues it advertises to the kernel (via alloc_etherdev_mq()) from a value received from the device to a constant value which is the minimum between 128 and the number of CPUs in the system. By allocating the net_device struct with a constant number of queues, the driver is able to allocate it at a much earlier stage, before calling any ena_com functions. This would allow to make all log prints in ena_com to use netdev_* log functions instead or current pr_* ones. Note: netdev_* prints in ena_com functions that are called before net_device registration in ena_probe() might print messages that are a bit ugly (with strings like "(unnamed net_device) (uninitialized)"). However we decided to use netdev_* prints in these functions anyway, for the sake of getting better messages later, when ena_com functions are called after ena_probe() form other parts of the driver.

2020-12-10iwlwifi: mvm: fix a race in CSA that caused assert 0x3420Sara Sharon
When we get a channel switch with a very long quiet period, we schedule a work to disconnect after a while. This work runs in background. In the meanwhile, we keep getting beacons and sending FW modify command for each. This has a potential race, where we modify the CSA after we aborted it. Protect the flow by setting csa_failed to true in case we abort, and check it before sending the modify command. This required a modification to the way we treat csa_failed in iwl_mvm_post_channel_switch: 1. The variable isn't being reset anymore, so we can still look at it in iwl_mvm_channel_switch_rx_beacon. This is fine, since we reset it when starting a new CSA. 2. There is no more early return in case of csa_failed. This is fine, since before this patch csa_failed was set only for GO, and for GO the function is only resetting the power settings, which we want to restore even in case of failure.

2020-12-10iwlwifi: pcie: remove MSIX_HW_INT_CAUSES_REG_IML handlingJohannes Berg
This is actually wrong, the bit used here by the image loader is BIT(1), not BIT(2). The latter will be reused by the new reset flow soon. However, as we never had any complaints about not printing the IML status or not handling the IML error interrupt (and I suspect the code handling it was incorrectly anyway) just remove the code for it.

2020-12-10iwlwifi: mvm: clean up scan state on failureJohannes Berg
We keep the scan status per UID in scan_uid_status field when the iwl_mvm_build_scan_cmd() function is called. If we error out after this, e.g. due to FW restart being in progress, we're not cleaning up properly, and can run into warnings later. Clean up internal variables when starting fails after calling the iwl_mvm_build_scan_cmd() function.

2020-12-10iwlwifi: mvm: do more useful queue sync accountingJohannes Berg
We're currently doing accounting on the queue sync with an atomic variable that counts down the number of remaining notifications that we still need. As we've been hitting issues in this area, modify this to track a bitmap of queues, not just the number of queues, and print out the remaining bitmap in the warning.

2020-12-10iwlwifi: mvm: fix 22000 series driver NMIJohannes Berg
For triggering an NMI in the firmware, we should only set BIT(24) in the corresponding register, not the entire mask that's usable by the driver. This currently doesn't matter because the firmware only enables BIT(24), but we'll start using BIT(25) for other purposes with an upcoming API change.

2020-12-10iwlwifi: pcie: change 12k A-MSDU config to use 16k buffersJohannes Berg
If 12k A-MSDU size is requested, we will actually allocate 16k due to page allocation. Thus, change it to actually mean 16k, which is useful for certain sniffer use cases.

2020-12-10iwlwifi: mvm: clear up iwl_mvm_notify_rx_queue() argument typeJohannes Berg
The argument type to iwl_mvm_notify_rx_queue() is currently just a u8 *, but that's misleading because we actually need the inner data to be of type struct iwl_mvm_internal_rxq_notif, because we interpret it when we get it back from the device (to check the sync bool and possibly the cookie.) Therefore, clear up any potential confusion and require that the data passed is of type struct iwl_mvm_internal_rxq_notif *. Also, while at it, rename the "count" to "notif_size" as "count" doesn't really clearly say what it's counting.
