Commit db3bdcb9c3ff -("mac80211: allow AP_VLAN operation on crypto controlled devices") -has introduced this change. - -Since 4addr AP operation also uses AP/VLAN iftype, this conditional -way of advertising AP/VLAN support has broken 4addr AP mode operation on -crypto controlled devices which do not support VLAN functionality. - -In the case of ath10k driver, not all firmwares have support for VLAN -functionality but all can support 4addr AP operation. Because AP/VLAN -support is not advertised for these devices, 4addr AP operations are -also blocked. - -Fix this by allowing 4addr operation on devices which do not support -AP/VLAN iftype but can support 4addr AP operation (decision is based on -the wiphy flag WIPHY_FLAG_4ADDR_AP). - -Cc: stable@vger.kernel.org -Fixes: db3bdcb9c3ff ("mac80211: allow AP_VLAN operation on crypto controlled devices") -Signed-off-by: Manikanta Pubbisetty <mpubbise@codeaurora.org> -Signed-off-by: Johannes Berg <johannes.berg@intel.com> ---- - include/net/cfg80211.h | 3 ++- - net/mac80211/util.c | 4 +++- - net/wireless/core.c | 6 +++++- - net/wireless/nl80211.c | 8 ++++++-- - 4 files changed, 16 insertions(+), 5 deletions(-) - ---- a/include/net/cfg80211.h -+++ b/include/net/cfg80211.h -@@ -3457,7 +3457,8 @@ struct cfg80211_ops { - * on wiphy_new(), but can be changed by the driver if it has a good - * reason to override the default - * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station -- * on a VLAN interface) -+ * on a VLAN interface).
