Since strlen(mp_path) can return 0, we'll end up accessing mp_path[-1] when the firmware_path isn't provided through the module arguments. So, fix this by just setting the end char to '\0' by default, and only changing it if we have a non-zero length. Additionally, use strnlen() with BRCMF_FW_ALTPATH_LEN instead of strlen() just to be extra safe.

2018-11-29brcmfmac: Call brcmf_dmi_probe before brcmf_of_probeHans de Goede1-1/+1
ARM systems with UEFI may have both devicetree (of) and DMI data in this case we end up setting brcmf_mp_device.board_type twice. In this case we should prefer the devicetree data, because: 1) The devicerree data is more reliable 2) Some ARM systems (e.g. the Raspberry Pi 3 models) support both UEFI and classic uboot booting, the devicetree data is always there, so using it makes sure we ask for the same nvram file independent of how we booted. This commit moves the brcmf_dmi_probe call to before the brcmf_of_probe call, so that the latter can override the value of the first if both are set.

2018-11-29brcmfmac: support STA info struct v7Dan Haab1-7/+33
The newest firmwares provide STA info using v7 of the struct. As v7 isn't backward compatible, a union is needed. Even though brcmfmac does not use any of the new info it's important to provide the proper struct buffer. Without this change new firmwares will fallback to the very limited v3 instead of something in between such as v4.

2018-11-23iwlwifi: fix cfg structs for 22000 with different RF modulesLuca Coelho3-4/+21
We have to choose different configuration and different firmwares depending on the external RF module that is installed. Since the external module is not represented in the PCI IDs, we need to change the configuration at runtime, after checking the RF ID of the module installed. We have a bit of a mess in the code that does this, because it applies cfg's according to the RF ID only, ignoring the integrated module that is in use. Fix that for some devices by adding correct configurations for them and not ignoring the integrated module's type when making the decision. Signed-off-by: Luca Coelho <[email protected]>

'shash' algorithms are always synchronous, so passing CRYPTO_ALG_ASYNC in the mask to crypto_alloc_shash() has no effect. Many users therefore already don't pass it, but some still do. This inconsistency can cause confusion, especially since the way the 'mask' argument works is somewhat counterintuitive. Thus, just remove the unneeded CRYPTO_ALG_ASYNC flags.
