Some scanning is done properly, though. >How-To-Repeat: I just used the same setup with Exim and exiscan to scan mail through clamd that I have used previously with clamav 0.74, which did not show the problem. >Fix: The problem appears to be is_fd_connected(), which is falsely indicating the socket is disconnected, causing clamd to emit the "client disconnected" message, and it closes the socket, causing Exim to complain about reading the response back. I stuck a "return 1;" in is_fd_connected() so it ALWAYS returns 1. This fixed the problem. Obviously it is not a very clean fix. Note: clamav-config.h has HAVE_POLL defined as 1 and HAVE_POLL_H undefined, so is_fd_connected() is using the select() version of the code. Gordon L.
