Subject: [PATCH 4.8 27/57] brcmfmac: fix pmksa->bssid usage
Date: Fri, 21 Oct 2016 11:17:50 +0200 [thread overview]
Message-ID: <20161021091436.706486923@linuxfoundation.org> (raw)
In-Reply-To: <20161021091435.435647262@linuxfoundation.org>
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicolas Iooss <nicolas.iooss_linux@m4x.org>
commit 7703773ef1d85b40433902a8da20167331597e4a upstream.
The struct cfg80211_pmksa defines its bssid field as:
const u8 *bssid;
contrary to struct brcmf_pmksa, which uses:
u8 bssid[ETH_ALEN];
Therefore in brcmf_cfg80211_del_pmksa(), &pmksa->bssid takes the address
of this field (of type u8**), not the one of its content (which would be
u8*). Remove the & operator to make brcmf_dbg("%pM") and memcmp()
behave as expected.
This bug have been found using a custom static checker (which checks the
usage of %p... attributes at build time). It has been introduced in
commit 6c404f34f2bd ("brcmfmac: Cleanup pmksa cache handling code"),
which replaced pmksa->bssid by &pmksa->bssid while refactoring the code,
without modifying struct cfg80211_pmksa definition.
Replace &pmk[i].bssid with pmk[i].bssid too to make the code clearer,
this change does not affect the semantic.
Fixes: 6c404f34f2bd ("brcmfmac: Cleanup pmksa cache handling code")
