https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264257 --- Comment #5 from John Baldwin <jhb@FreeBSD.org> --- Looks like it walked off the end of the mbuf chain as it tried to copy one = byte too many. You could try going up to frame 8 (tcp_output) to see if the arguments passed to m_copydata() are still around (looks like we know the m= buf chain via m@entry for frame 9, but knowing the original length and offset a= nd confirming it walked off the end would be good). You'd have to figure out = why the length was wrong though and that might need more digging in the tp or t= he like. --=20 You are receiving this mail because: You are on the CC list for the bug.
