From: Rafał Miłecki Date: Tue, 8 Jan 2019 09:01:08 +0000 (+0100) Subject: mac80211: brcmfmac: backport firmware loading changes & fix memory bugs X-Git-Tag: v18.06.2~38 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a8cc06c5371eca2ae8ab4511c7136d0ebd9ee3bc;p=openwrt%2Fstaging%2Fchunkeey.git mac80211: brcmfmac: backport firmware loading changes & fix memory bugs This pick most of brcmfmac changes backported into the master in commits 5932eb690f24 ("mac80211: brcmfmac: backport firmware loading cleanup") 3eab6b8275b2 ("mac80211: brcmfmac: backport NVRAM loading improvements") 529c95cc15dc ("mac80211: brcmfmac: fix use-after-free & possible NULL pointer dereference") It's more than would be normally backported into a stable branch but it seems required. Firmware loading cleanups are needed to allow fix memory bugs in a reliable way. Memory fixes are really important to avoid corrupting memory and risking a NULL pointer dereference. Hopefully this stuff has received enough testing in the master.
