On non-aligned platforms, properly cast argument before left-shifting it in ngx_http_v2_parse_uint32 that is used with u_char. Otherwise it propagates to int to hold the value and can step over the sign bit. Usually, on known compilers, this results in negation. Furthermore, a subsequent store into a wider type, that is ngx_uint_t on 64-bit platforms, results in sign-extension. In practice, this can be observed in debug log as a very large exclusive bit value, when client sent PRIORITY frame with exclusive bit set: : *14 http2 PRIORITY frame sid:5 on 1 excl:8589934591 weight:17 Found with UndefinedBehaviorSanitizer. |
