2019-09-10nfp: honor FW reset and loading policiesDirk van der Merwe
The firmware reset and loading policies can be controlled with the combination of three hwinfo keys, 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'. 'app_fw_from_flash' defines which firmware should take precedence, 'Disk', 'Flash' or the 'Preferred' firmware. When 'Preferred' is selected, the management firmware makes the decision on which firmware will be loaded by comparing versions of the flash firmware and the host supplied firmware. 'abi_drv_reset' defines when the driver should reset the firmware when the driver is probed, either 'Disk' if firmware was found on disk, 'Always' reset or 'Never' reset. Note that the device is always reset on driver unload if firmware was loaded when the driver was probed. 'abi_drv_load_ifc' defines a list of PF devices allowed to load FW on the device. Furthermore, we limit the cases to where the driver will unload firmware again when the driver is removed to only when firmware was loaded by the driver and only if this particular device was the only one that could have loaded firmware. This is needed to avoid firmware being removed while in use on multi-host platforms.

2019-09-10nfp: nsp: add support for optional hwinfo lookupDirk van der Merwe
There are cases where we want to read a hwinfo entry from the NFP, and if it doesn't exist, use a default value instead. To support this, we must silence warning/error messages when the hwinfo entry doesn't exist since this is a valid use case. The NSP command structure provides the ability to silence command errors, in which case the caller should log any command errors appropriately. Protocol errors are unaffected by this.

For sdio chip, if the rssi is not good, then it have some retry, firmware will indicate the msdu list of a ppdu with a hole, it means it lost the hole msdu, after the msdu retry from AP, the hole msdu will indicate from firmware later. The hole msdu's PN check will fail and the hole msdu will be dropped. PN check fail example: Sequence number PN number PN check status 3814 6101 success 3815 6102 success 3816 6103 success 3818 6105 success 3819 6106 success 3820 6107 success 3817 6104 fail The correct logic is reorder the msdu list and then do PN check. ieee80211_rx_reorder_ampdu of mac80211 will do the reorer logic and then do PN check in ieee80211_rx_h_decrypt of mac80211. example after reorder: Sequence number PN number PN check status 3814 6101 success 3815 6102 success 3816 6103 success 3817 6104 success 3818 6105 success 3819 6106 success 3820 6107 success Tested with QCA6174 SDIO with firmware WLAN.RMH.4.4.1-00017-QCARMSWP-1.

2019-09-09ixgbe: sync the first fragment unconditionallyFiro Yang
In Xen environment, if Xen-swiotlb is enabled, ixgbe driver could possibly allocate a page, DMA memory buffer, for the first fragment which is not suitable for Xen-swiotlb to do DMA operations. Xen-swiotlb have to internally allocate another page for doing DMA operations. This mechanism requires syncing the data from the internal page to the page which ixgbe sends to upper network stack. However, since commit f3213d932173 ("ixgbe: Update driver to make use of DMA attributes in Rx path"), the unmap operation is performed with DMA_ATTR_SKIP_CPU_SYNC. As a result, the sync is not performed. Since the sync isn't performed, the upper network stack could receive a incomplete network packet. By incomplete, it means the linear data on the first fragment(between skb->head and skb->end) is invalid. So we have to copy the data from the internal xen-swiotlb page to the page which ixgbe sends to upper network stack through the sync operation. More details from Alexander Duyck: Specifically since we are mapping the frame with DMA_ATTR_SKIP_CPU_SYNC we have to unmap with that as well. As a result a sync is not performed on an unmap and must be done manually as we skipped it for the first frag. As such we need to always sync before possibly performing a page unmap operation.

2019-09-09i40e: Implement debug macro hw_dbg using dev_dbgMauro S. M. Rodrigues
There are several uses of hw_dbg in the code, producing no output. This patch implements it using dev_debug. Initially the intention was to implement it using netdev_dbg, analogously to what is done in ixgbe for instance. That approach was avoided due to some early usages of hw_dbg, like i40e_pf_reset, before the VSI structure initialization causing NULL pointer dereference during the driver probe if the debug messages were turned on as soon as the module is probed. v2: - Use dev_dbg instead of pr_debug, and take advantage of dev_name instead of crafting pretty much the same device name locally as suggested by Jakub Kicinski.

After hot plugging an 1Gbps Ethernet cable with 1Gbps link partner, the MII_BMSR may report 10Mbps, renders the network rather slow. The issue has much lower fail rate after commit 59653e6497d1 ("e1000e: Make watchdog use delayed work"), which essentially introduces some delay before running the watchdog task. But there's still a chance that the hot plugging event and the queued watchdog task gets run at the same time, then the original issue can be observed once again. So let's use mod_delayed_work() to add a deterministic 1 second delay before running watchdog task, after an interrupt.

2019-09-07nfp: flower: cmsg rtnl locks can timeout reify messagesFred Lotter
Flower control message replies are handled in different locations. The truly high priority replies are handled in the BH (tasklet) context, while the remaining replies are handled in a predefined Linux work queue. The work queue handler orders replies into high and low priority groups, and always start servicing the high priority replies within the received batch first. Reply Type: Rtnl Lock: Handler: CMSG_TYPE_PORT_MOD no BH tasklet (mtu) CMSG_TYPE_TUN_NEIGH no BH tasklet CMSG_TYPE_FLOW_STATS no BH tasklet CMSG_TYPE_PORT_REIFY no WQ high CMSG_TYPE_PORT_MOD yes WQ high (link/mtu) CMSG_TYPE_MERGE_HINT yes WQ low CMSG_TYPE_NO_NEIGH no WQ low CMSG_TYPE_ACTIVE_TUNS no WQ low CMSG_TYPE_QOS_STATS no WQ low CMSG_TYPE_LAG_CONFIG no WQ low A subset of control messages can block waiting for an rtnl lock (from both work queue priority groups). The rtnl lock is heavily contended for by external processes such as systemd-udevd, systemd-network and libvirtd, especially during netdev creation, such as when flower VFs and representors are instantiated. Kernel netlink instrumentation shows that external processes (such as systemd-udevd) often use successive rtnl_trylock() sequences, which can result in an rtnl_lock() blocked control message to starve for longer periods of time during rtnl lock contention, i.e. netdev creation. In the current design a single blocked control message will block the entire work queue (both priorities), and introduce a latency which is nondeterministic and dependent on system wide rtnl lock usage. In some extreme cases, one blocked control message at exactly the wrong time, just before the maximum number of VFs are instantiated, can block the work queue for long enough to prevent VF representor REIFY replies from getting handled in time for the 40ms timeout. The firmware will deliver the total maximum number of REIFY message replies in around 300us. Only REIFY and MTU update messages require replies within a timeout period (of 40ms). The MTU-only updates are already done directly in the BH (tasklet) handler. Move the REIFY handler down into the BH (tasklet) in order to resolve timeouts caused by a blocked work queue waiting on rtnl locks.

2019-09-07net/hamradio/6pack: Fix the size of a sk_buff used in 'sp_bump()'Christophe JAILLET
We 'allocate' 'count' bytes here. In fact, 'dev_alloc_skb' already add some extra space for padding, so a bit more is allocated. However, we use 1 byte for the KISS command, then copy 'count' bytes, so count+1 bytes. Explicitly allocate and use 1 more byte to be safe.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-09-05 This series contains updates to ice driver. Brett fixes the setting of num_q_vectors by using the maximum number between the allocated transmit and receive queues. Anirudh simplifies the code to use a helper function to return the main VSI, which is the first element in the pf->vsi array. Adds a pointer check to prevent a NULL pointer dereference. Adds a check to ensure we do not initialize DCB on devices that are not DCB capable. Does some housekeeping on the code to remove unnecessary indirection and reduce the PF structure by removing elements that are not needed since the values they were storing can be readily gotten from ice_get_avail_*_count()'s. Updates the printed strings to make it easier to search the logs for driver capabilities. Jesse cleans up unnecessary function arguments. Updated the code to use prefetch() to add some efficiency to the driver to avoid a cache miss. Did some housekeeping on the code to remove the configurable transmit work limit via ethtool which ended up creating performance overhead. Made additional performance enhancements by updating the driver to start out with a reasonable number of descriptors by changing the default to 2048. Mitch fixes the reset logic for VFs by clearing VF_MBX_ARQLEN register when the source of the reset is not PFR. Lukasz updates the driver to include a similar fix for the i40e driver by reporting link down for VF's when the PF queues are not enabled. Akeem updates the driver to report the VF link status once we get VF resources so that we can reflect the link status similarly to how the PF reports link speed. Ashish updates the transmit context structure based on recent changes to the hardware specification. Dave updates the DCB logic to allow a delayed registration for MIB change events so that the driver is not accepting events before it is ready for them. ==================== Signed-off-by: David S.
