2019-02-19brcmfmac: support firmware reporting 160 MHz channelsRafał Miłecki
So far 160 MHz channels were treated as 20 MHz ones which was breaking support for 40/80 MHz due to the brcmf_construct_chaninfo() logic and its assumptions. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-19brcmfmac: improve code handling bandwidth of firmware reported channelsRafał Miłecki
1) Use switch to simplify/improve the code & avoid some duplication 2) Add warning for unsupported values Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-19brcmfmac: print firmware reported ring status errorsRafał Miłecki
Firmware is capable of reporting ring status. It's used e.g. to signal some problem with a specific ring setup. This patch adds support for printing ring & error number which may be useful for debugging setup issues.

2019-02-19brcmfmac: use chipname in brcmf_fw_alloc_request() for error path as wellArend van Spriel
The local variable chipname is string representation of chip id and revision which is printed in the good flow of brcmf_fw_alloc_request(). Also use it for the error path, ie. for unknown/unsupported devices.

2019-02-19brcmfmac: check and dump trap info during sdio probeArend van Spriel
When the firmware crashes during the probe sequence we provide little information on what really failed. This patch checks the sdpcm shared location and show the trap information if a firmware trap has happened.

2019-02-19brcmfmac: disable MBSS feature for bcm4330 deviceArend van Spriel
The MBSS feature was already disabled for bcm43362 as it resulted in a beacon with BRCM_TEST_SSID regardless user configuration in hostapd. Now the same has been reported for bcm4330 so disable the feature for this device as well.

2019-02-19brcmfmac: create debugfs files for bus-specific layerArend van Spriel
Since we moved the drivers debugfs directory under ieee80211 debugfs the debugfs entries need to be added after wiphy_register() has been called. For most part that has been done accordingly, but for the debugfs entries added by SDIO it was not and failed silently. This patch fixes that by adding a bus-layer callback for it.

2019-02-19brcmfmac: add subtype check for event handling in data pathArend van Spriel
For USB there is no separate channel being used to pass events from firmware to the host driver and as such are passed over the data path. In order to detect mock event messages an additional check is needed on event subtype. This check is added conditionally using unlikely() keyword.

2019-02-19ARM: dts: armada-xp: fix Armada XP boards NAND descriptionThomas Petazzoni
Commit 3b79919946cd2cf4dac47842afc9a893acec4ed7 ("ARM: dts: armada-370-xp: update NAND node with new bindings") updated some Marvell Armada DT description to use the new NAND controller bindings, but did it incorrectly for a number of boards: armada-xp-gp, armada-xp-db and armada-xp-lenovo-ix4-300d. Due to this, the NAND is no longer detected on those platforms. This commit fixes that by properly using the new NAND DT binding. This commit was runtime-tested on Armada XP GP, the two other platforms are only compile-tested.

2019-02-19powerpc/powernv/sriov: Register IOMMU groups for VFsAlexey Kardashevskiy
The compound IOMMU group rework moved iommu_register_group() together in pnv_pci_ioda_setup_iommu_api() (which is a part of ppc_md.pcibios_fixup). As the result, pnv_ioda_setup_bus_iommu_group() does not create groups any more, it only adds devices to groups. This works fine for boot time devices. However IOMMU groups for SRIOV's VFs were added by pnv_ioda_setup_bus_iommu_group() so this got broken: pnv_tce_iommu_bus_notifier() expects a group to be registered for VF and it is not. This adds missing group registration and adds a NULL pointer check into the bus notifier so we won't crash if there is no group, although it is not expected to happen now because of the change above.

2019-02-18exec: load_script: Do not exec truncated interpreter pathKees Cook
Commit 8099b047ecc4 ("exec: load_script: don't blindly truncate shebang string") was trying to protect against a confused exec of a truncated interpreter path. However, it was overeager and also refused to truncate arguments as well, which broke userspace, and it was reverted. This attempts the protection again, but allows arguments to remain truncated. In an effort to improve readability, helper functions and comments have been added.

2019-02-18Merge branch 'net-phy-add-helpers-for-handling-C45-10GBT-AN-register-values'David S. Miller
Heiner Kallweit says: ==================== net: phy: add helpers for handling C45 10GBT AN register values Similar to the existing helpers for the Clause 22 registers add helpers to deal with converting Clause 45 advertisement registers to / from link mode bitmaps. Note that these helpers are defined in linux/mdio.h, not like the Clause 22 helpers in linux/mii.h. Reason is that the Clause 45 register constants are defined in uapi/linux/mdio.h. And uapi/linux/mdio.h includes linux/mii.h before defining the C45 register constants. v2: - Remove few helpers which aren't used by this series. They will follow together with the users. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
