In that case, it erroneously drops the NUL which should be part of the following packet. The bug was caused by using 0 as a sentinel value in a variable that could legitimately hold 0. Fix it by switching the sentinel value to -1. PR: 178055 Reported by: Richard <rsitze@gmail.com> Reviewed by: cem Differential Revision: https://reviews.freebsd.org/D16853 |
