Subject: [PATCH] brcmfmac: Fix out of bounds memory access during fw load
I ended up tracking down some rather nasty issues with f2fs (and other
filesystem modules) constantly crashing on my kernel down to a
combination of out of bounds memory accesses, one of which was coming
from brcmfmac during module load:

[ 31.096533] Disabling lock debugging due to kernel taint
It appears that when trying to determine the length of the string in the
alternate firmware path, we make the mistake of not handling the case
where the firmware path is empty correctly. 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.

Subject: [PATCH] brcmfmac: fix roamoff=1 modparam
When the update_connect_param callback is set, nl80211 expects the flag
WIPHY_FLAG_SUPPORTS_FW_ROAM to be set as well. However, this flag is
only set when modparam roamoff=0, while the callback is set
unconditionally. Since commit 7f9a3e150ec7 this causes a warning in
wiphy_register, which breaks brcmfmac.
Disable the update_connect_param callback when roamoff=0 to fix this.

Since commit 1204aa17f3b4 ("brcmfmac: set WIPHY_FLAG_HAVE_AP_SME flag")

hostapd (device_ap_sme=1 use_monitor=0):

Subject: [PATCH] brcmfmac: modify __brcmf_err() to take bus as a parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far __brcmf_err() was using pr_err() which didn't allow identifying
device that was affected by an error. It's crucial for systems with more
than 1 device supported by brcmfmac (a common case for home routers).
This change allows passing struct brcmf_bus to the __brcmf_err(). That
struct has been agreed to be the most common one. It allows accessing
struct device easily & using dev_err() printing helper.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
It makes error messages more meaningful and is important for debugging
errors/bugs on systems with multiple brcmfmac supported devices.
All bus files should follow & get updated similarly (soon).
