Package: dovecot-core
Version: 1:2.4.1+dfsg1-6
Severity: important
Dear Maintainer,
* What led up to the situation?
Upgrade from 2.3.21.1+dfsg1-1+b2 to 1:2.4.1+dfsg1-6
* What was the outcome of this action?
Logs are flooded with messages "Warning: Time moved forward"
Dovecot version:
1:2.4.1+dfsg1-6 (Architecture: i386)
Operating system:
Linux lar 6.13.7-64+ #1 SMP PREEMPT Fri Mar 21 08:33:47 MEZ 2025 x86_64
GNU/Linux
OS Description: Debian GNU/Linux 13 (trixie)
Problem Description:
The function io_loop_get_wait_time in ioloop.c contains the line:
ioloop->next_max_time.tv_sec = (1ULL << (TIME_T_MAX_BITS-1)) - 1;
On 32-bit systems TIME_T_MAX_BITS is 31 such that the result of this
calculation is 1073741823. Far from the intended "infinity" and even before
"now". This leads to problems in the function io_loop_handle_timeouts_real:
the calculation of the time difference between now and next_max_time is then
something like -693628953 seconds which confuses dovecot and floods the logs
with these warnings:
Jan 02 17:43:43 lmtp(38364): Warning: Time moved forward 693630400.301863
seconds
Jan 02 17:43:43 lmtp(38364): Warning: Time moved forward 693630400.304144
seconds
Jan 02 17:45:43 lmtp(38364): Warning: Time moved forward 693630520.416053
seconds
Thanks for your consideration,
Andy
