The actual parsing for INT_RANGE is done by +wpa_config_parse_int which can only store the result as full integer. + +max_oper_chwidth is stored as u8 (a single byte) in wpa_ssid. This means +that on little endian systems, the least significant byte of the parsed +value are really stored in the max_oper_chwidth. But on big endian system, +the only most significant byte is stored as max_oper_chwidth. This means +that 0 is always stored because the provided range doesn't allow any other +value for systems with multi-byte-wide integers. + +This also means that for common systems with 4-byte-wide integers, the +remaining 3 bytes were written after the actual member of the struct. This +should not have influenced the behavior of succeeding members because these +bytes would have been part of the padding between the members on most +systems. + +Increasing its size to a full int fixes the write operations outside of the +member and allows to use the max_oper_chwidth setting on big endian +systems. + +Fixes: 0f29bc68d18e ("IBSS/mesh: Add support for VHT80P80 configuration") +Signed-off-by: Sven Eckelmann <sven.eckelmann@openmesh.com> + +Forwarded: https://patchwork.ozlabs.org/patch/909751/ +--- + wpa_supplicant/config_ssid.h | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/wpa_supplicant/config_ssid.h ++++ b/wpa_supplicant/config_ssid.h +@@ -503,7 +503,7 @@ struct wpa_ssid { + + int vht; + +- u8 max_oper_chwidth; ++ int max_oper_chwidth; + + unsigned int vht_center_freq1; + unsigned int vht_center_freq2; |
