From: Sven Eckelmann <seckelmann@xxxxxxxxx> The the mask for PPE threshold present in the HE phy capability byte 6 is 0x80 and not 0x6. The latter breaks the length calculation and the acceptance of the HE capabilities for STAs which either: * don't have PPE threshold present AND the highest bit of the sounding dimension <= 80 Mhz or lowest bit of the sounding dimension > 80Mhz set * do have PPE threshold present AND not the highest bit of the sounding dimension <= 80 Mhz and not lowest bit of the sounding dimension > 80Mhz set Fixes: 8f5fc369e263 ("HE: Fix HE Capabilities element variable length encoding") Signed-off-by: Sven Eckelmann <seckelmann@xxxxxxxxx> --- Cc: John Crispin <john@xxxxxxxxxxx> Cc: Shashidhar Lakkavalli <slakkavalli@xxxxxxxxx> --- src/ap/ieee802_11_he.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/ap/ieee802_11_he.c b/src/ap/ieee802_11_he.c index ba22a174a..d3d3c1db3 100644 --- a/src/ap/ieee802_11_he.c +++ b/src/ap/ieee802_11_he.c @@ -23,7 +23,7 @@ static u8 ieee80211_he_ppet_size(u8 ppe_thres_hdr, const u8 *phy_cap_info) u8 sz = 0, ru; if ((phy_cap_info[HE_PHYCAP_PPE_THRESHOLD_PRESENT_IDX] & - HE_PHYCAP_PPE_THRESHOLD_PRESENT_IDX) == 0) + HE_PHYCAP_PPE_THRESHOLD_PRESENT) == 0) return 0; ru = (ppe_thres_hdr >> HE_PPE_THRES_RU_INDEX_BITMASK_SHIFT) & -- 2.20.1 _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
