Subject: GPSD time will jump back 1024 weeks at after week=2180
(23-October-2021)
Hi,
the following mail is from the gpsd-users list, forwarding it as this will
most likely affect a lot of ntp servers and various self driving/navigating
vehicles/submarines/.... Please note that I did not check how chrony/ntpd
handle sudden jumps back in time from gps.
I know that upstream does not care about CVEs, but due to the widespread use
of gpsd assigning a CVE might be warranted.

Yo All!
Fair warning. Issue 144: https://gitlab.com/gpsd/gpsd/-/issues/144
"GPSD time will jump back 1024 weeks at after week=2180 (23-October-2021)"
The offending commit was after 3.19, so only 3.20, 3.21 and 3.22 are
affected:
commit cb7367496f6dd5f90c6b067c031b327921a857b2

The commit 7f30d88d fixes the problem for those that want to try to back port
the fix. You'll just be without all the other bug fixes..
This is a real good reason to get 3.23 out very soon. Please test!

Cheers,
Bernd
