This includes a bunch of fixups for issues reported by lockdep. * ethtool routines can assume RTNL * send is done with RCU lock (and BH disable) * avoid refetching internal device struct (netvsc) instead pass it as a parameter. Signed-off-by:Stephen Hemminger <sthemmin@microsoft.com> Signed-off-by:

bnxt_en depends on MAY_USE_DEVLINK; this is used to force bnxt_en to be =m when DEVLINK is =m. Now, bnxt_re selects bnxt_en. Unless bnxt_re also explicitly calls out dependency on MAY_USE_DEVLINK, Kconfig does not force bnxt_re to be =m when DEVLINK is =m, causing the following error: drivers/net/ethernet/broadcom/bnxt/bnxt_vfr.o: In function `bnxt_dl_register': bnxt_vfr.c:(.text+0x1440): undefined reference to `devlink_alloc' bnxt_vfr.c:(.text+0x14c0): undefined reference to `devlink_register' bnxt_vfr.c:(.text+0x14e0): undefined reference to `devlink_free' drivers/net/ethernet/broadcom/bnxt/bnxt_vfr.o: In function `bnxt_dl_unregister': bnxt_vfr.c:(.text+0x1534): undefined reference to `devlink_unregister' bnxt_vfr.c:(.text+0x153c): undefined reference to `devlink_free' Fix this by adding MAY_USE_DEVLINK dependency in bnxt_re.

Apparently through one of my revisions of the initial patches series I lost the devmap test. We can add more testing later but for now lets fix the simple one we have. Fixes: 546ac1ff "bpf: add devmap, a map for storing net device references" Reported-by:

Ursula Braun says: ==================== net/smc: get rid of unsafe_global_rkey The smc code uses the unsafe_global_rkey, exposing all memory for remote reads and writes once a connection is established. Here is now a patch series to get rid of unsafe_global_rkey usage. Main idea is to switch to SG-logic and separate memory regions for RMBs. ==================== Signed-off-by: -

SMC currently uses the unsafe_global_rkey of the protection domain, which exposes all memory for remote reads and writes once a connection is established. This patch introduces separate memory regions with separate rkeys for every RMB. Now the unsafe_global_rkey of the protection domain is no longer needed. Signed-off-by:

The follow-on patch makes use of ib_map_mr_sg() when introducing separate memory regions for RMBs. This function is based on scatterlists; thus this patch introduces scatterlists for RMBs. Signed-off-by:

Ursula Braun authored
If a link group for a new server connection exists already, the mutex serializing the determination of link groups is given up early. The coming registration of memory regions benefits from the serialization as well, if the mutex is held till connection creation is finished. This patch postpones the unlocking of the link group creation mutex. Signed-off-by:

Jakub Kicinski says: ==================== nfp: extend firmware request logic We have been pondering for some time how to support loading different application firmwares onto NFP. We want to support both users selecting one of the firmware images provided by Netronome (which are optimized for different use cases each) as well as firmware images created by users themselves or other companies. In the end we decided to go with the simplest solution - depending on the right firmware image being placed in /lib/firmware. This vastly simplifies driver logic and also doesn't require any new API. Different NICs on one system may want to run different applications therefore we first try to load firmware specific to the device (by serial number of PCI slot) and if not present try the device model based name we have been using so far. ==================== Signed-off-by: -

request_firmware() will fallback to user space helper and may cause long delays when driver is loaded if udev doesn't correctly handle FW requests. Since we never really made use of the user space helper functionality switch to the simpler request_firmware_direct() call. The side effect of this change is that no warning will be printed when the FW image does not exists. To help users figure out which FW file is missing print a info message when we request each file.

We generally look up firmware by card type, but that doesn't allow users who have more than one card of the same type in their system to select firmware per adapter. Unfortunately user space firmware helper seems fraught with difficulties and to be on its way out. In particular support for handling firmware uevents have been dropped from systemd and most distributions don't enable the FW fallback by default any more. To allow users selecting firmware for a particular device look up firmware names by serial and pci_name(). Use the direct lookup to disable generating uevents when enabled in Kconfig and not print any warnings to logs if adapter-specific files are missing. Users can place in /lib/firmware/netronome files named: pci-${pci_name}.nffw serial-${serial}.nffw to target a specific card. E.g.: pci-0000:04:00.0.nffw pci-0000:82:00.0.nffw serial-00-aa-bb-11-22-33-10-ff.nffw We use the full serial number including the interface id, as it appears in lspci output (bytes separated by '-').

We use a hack to defer probe when firmware was not pre-loaded or found on disk. This helps in case users forgot to include firmware in initramfs, the driver will most likely get another shot at probing after real root is mounted. This is not for what EPROBE_DEFER is supposed to be used, and when FW is completely missing every time new device is probed NFP will reprobe spamming kernel logs. Remove this hack, users will now have to make sure the right firmware image is present in initramfs if nfp.ko is placed there or built in. Signed-off-by:
