Subject: [PATCH] brcmfmac: fix pmksa->bssid usage
|
|
|
|
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.
|
|
