2019-09-10Merge branch 'nfp-implement-firmware-loading-policy'David S. Miller
Simon Horman says: ==================== nfp: implement firmware loading policy Dirk says: This series adds configuration capabilities to the firmware loading policy of the NFP driver. NFP firmware loading is controlled via three HWinfo keys which can be set per device: 'abi_drv_reset', 'abi_drv_load_ifc' and 'app_fw_from_flash'. Refer to patch #11 for more detail on how these control the firmware loading. In order to configure the full extend of FW loading policy, a new devlink parameter has been introduced, 'reset_dev_on_drv_probe', which controls if the driver should reset the device when it's probed. This, in conjunction with the existing 'fw_load_policy' (extended to include a 'disk' option) provides the means to tweak the NFP HWinfo keys as required by users. Patches 1 and 2 adds the devlink modifications and patches 3 through 9 adds the support into the NFP driver. Furthermore, the last 2 patches are documentation only. v2: Renamed all 'reset_dev_on_drv_probe' defines the same as the devlink parameter name (Jiri) ==================== Signed-off-by: David S.

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.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-09-09 This series contains a variety of cold and hot savoury changes to Intel drivers. Some of the fixes could be considered for stable even though the author did not request it. Hulk Robert cleans up (i.e. removes) a function that has no caller for the iavf driver. Radoslaw fixes an issue when there is no link in the VM after the hypervisor is restored from a low-power state due to the driver not properly restoring features in the device that had been disabled during the suspension for ixgbevf. Kai-Heng Feng modified e1000e to use mod_delayed_work() to help resolve a hot plug speed detection issue by adding a deterministic 1 second delay before running watchdog task after an interrupt. Sasha moves functions around to avoid forward declarations, since the forward declarations are not necessary for these static functions in igc. Also added a check for igc during driver probe to validate the NVM checksum. Cleaned up code defines that were not being used in the igc driver. Adds support for IP generic transmit checksum offload in the igc driver. Updated the iavf kernel documentation by a developer with no life. Jake provides another fm10k update to a local variable for ease of code readability. Mitch fixes the iavf driver to allow the VF to override the MAC address set by the host, if the VF is in "trusted" mode. Mauro S. M. Rodrigues provides several changes for i40e driver, first with resolving hw_dbg usage and referencing a i40e_hw attribute. Also implemented a debug macro using pr_debug, since the use of netdev_dbg could cause a NULL pointer dereference during probe. Finally cleaned up code that is no longer used or needed. Firo Yang provides a change in the ixgbe driver to ensure we sync the first fragment unconditionally to help resolve an issue seen in the XEN environment when the upper network stack could receive an incomplete network packet. Mariusz adds a missing device to the i40e PCI table in the driver. v2: Mauro S. M. Rodrigues updated patches 10 & 11 of the series based on feedback from Jakub Kicinski. Also updated patch 13 description so that the "Fixes:" tag was no wrapped. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

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.

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.

2019-09-07net/tls: remove the record tail optimizationJakub Kicinski
For TLS device offload the tag/message authentication code are filled in by the device. The kernel merely reserves space for them. Because device overwrites it, the contents of the tag make do no matter. Current code tries to save space by reusing the header as the tag. This, however, leads to an additional frag being created and defeats buffer coalescing (which trickles all the way down to the drivers). Remove this optimization, and try to allocate the space for the tag in the usual way, leave the memory uninitialized. If memory allocation fails rewind the record pointer so that we use the already copied user data as tag. Note that the optimization was actually buggy, as the tag for TLS 1.2 is 16 bytes, but header is just 13, so the reuse may had looked past the end of the page..

2019-09-07ipmr: remove hard code cache_resolve_queue_len limitHangbin Liu
This is a re-post of previous patch wrote by David Miller[1]. Phil Karn reported[2] that on busy networks with lots of unresolved multicast routing entries, the creation of new multicast group routes can be extremely slow and unreliable. The reason is we hard-coded multicast route entries with unresolved source addresses(cache_resolve_queue_len) to 10. If some multicast route never resolves and the unresolved source addresses increased, there will be no ability to create new multicast route cache. To resolve this issue, we need either add a sysctl entry to make the cache_resolve_queue_len configurable, or just remove cache_resolve_queue_len limit directly, as we already have the socket receive queue limits of mrouted socket, pointed by David. >From my side, I'd perfer to remove the cache_resolve_queue_len limit instead of creating two more(IPv4 and IPv6 version) sysctl entry. [1] https://lkml.org/lkml/2018/7/22/11 [2] https://lkml.org/lkml/2018/7/21/343 v3: instead of remove cache_resolve_queue_len totally, let's only remove the hard code limit when allocate the unresolved cache, as Eric Dumazet suggested, so we don't need to re-count it in other places. v2: hold the mfc_unres_lock while walking the unresolved list in queue_count(), as Nikolay Aleksandrov remind.
