When not -specified by user-space, the driver generates the MAC address for -the P2P_DEVICE interface using the MAC address of the primary -interface and setting the locally administered bit. However, the MAC -address of the primary interface may already have that bit set causing -the creation of the P2P_DEVICE interface to fail with -EBUSY. Fix this -by using a random address instead to determine the P2P_DEVICE address. - -Cc: stable@vger.kernel.org # 3.10.y -Reported-by: Hans de Goede <hdegoede@redhat.com> -Reviewed-by: Hante Meuleman <hante.meuleman@broadcom.com> -Reviewed-by: Pieter-Paul Giesberts <pieter-paul.giesberts@broadcom.com> -Reviewed-by: Franky Lin <franky.lin@broadcom.com> -Signed-off-by: Arend van Spriel <arend.vanspriel@broadcom.com> -Signed-off-by: Kalle Valo <kvalo@codeaurora.org> ---- - .../net/wireless/broadcom/brcm80211/brcmfmac/p2p.c | 24 ++++++++++------------ - 1 file changed, 11 insertions(+), 13 deletions(-) - ---- a/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c -+++ b/drivers/net/wireless/broadcom/brcm80211/brcmfmac/p2p.c -@@ -462,25 +462,23 @@ static int brcmf_p2p_set_firmware(struct - * @dev_addr: optional device address. - * - * P2P needs mac addresses for P2P device and interface.
