Section 7.2 7.3 says:
Kseq = HMAC(Kss, "fortybits", (int32)0); // len includes terminating null memset(Kseq+7, 0xab, 7)
It should say:
Kseq = HMAC(Kss, "fortybits", (int32)0); // len includes terminating null memset(Kseq+7, 0xab, 9)
Notes:
applies both to section 7.2 and 7.3, confirmed by Larry Zhu
