As reported in GH issue #109 and in discourse issue https://discourse.haproxy.org/t/haproxy-returns-408-or-504-error-when-timeout-client-value-is-every-25d the time parser doesn't error on overflows nor underflows. This is a recurring problem which additionally has the bad taste of taking a long time before hitting the user. This patch makes parse_time_err() return special error codes for overflows and underflows, and adds the control in the call places to report suitable errors depending on the requested unit. In practice, underflows are almost never returned as the parsing function takes care of rounding values up, so this might possibly happen on 64-bit overflows returning exactly zero after rounding though. It is not really possible to cut the patch into pieces as it changes the function's API, hence all callers. Tests were run on about every relevant part (cookie maxlife/maxidle, server inter, stats timeout, timeout*, cli's set timeout command, tcp-request/response inspect-delay).
