Description Sebastian Pipping gentoo-dev 2023-04-14 19:13:53 UTC
Patches not yet available to my best knowledge, see URL above for latest developments.  Mostly opening this ticket so you know what's coming.
Comment 1 Sebastian Pipping gentoo-dev 2023-04-14 20:41:30 UTC
PS: Given the state of net-misc/ntp upstream and downstream, I wonder if we should hard mask it for future removal and recommend use of net-misc/ntpsec instead.  Based on what https://packages.debian.org/bookworm/ntp says about "dummy transitional package to transition to NTPsec", the upcoming Debian stable seems to have gone that very route.

Ping, maintainers? Shall we last rite?
Comment 3 Mike Gilbert gentoo-dev 2023-05-01 00:28:40 UTC
No, I don't think we will last rite over a bug in the rarely used ntpq utility.
Comment 4 Sebastian Pipping gentoo-dev 2023-05-01 00:51:03 UTC
Hi Mike, what do you suggest how to deal best with absence of patches to vulnerabilities and no upstream release for near three years?
Wouldn't it be great if users migrated to something less zombie like ntpsec or chrony, instead?

It's been ~3 weeks since the references CVEs were published. What's the rush?

There is nothing stopping users from migrating.
Comment 6 Mike Gilbert gentoo-dev 2023-05-01 01:19:33 UTC
Eh, I guess ntpsec is basically a drop-in replacement, so there's no strong reason to keep ntp around. Objection withdrawn.
Comment 7 Sebastian Pipping gentoo-dev 2023-05-01 01:28:28 UTC
Thank you!
Comment 8 Patrick McLean gentoo-dev 2023-05-15 20:28:30 UTC
I have a minor concern. ntpsec took quite a bit longer than other packages to add openssl-3.0 compatibility. If they are going to be this slow to library updates in the future, then it may be worth keeping ntp around so users have an option.
Comment 9 Mike Gilbert gentoo-dev 2023-05-15 20:36:21 UTC
(In reply to Patrick McLean from comment #8)

Slow updates from ntpsec are better than no updates from ntp.

The handbook recommends net-misc/chrony anyway.

    net-misc/ntp: add 4.2.8_p16
    
    We don't need to generate our own man pages, see:
    ```
     * CMP: =net-misc/ntp-4.2.8_p15-r6 with net-misc/ntp-4.2.8_p16/image
     *  FILES:-usr/share/man/man8/keygen.8.xz
     *  FILES:-usr/share/man/man8/ntpd.8.xz
     *  FILES:-usr/share/man/man8/ntpdate.8.xz
     *  FILES:-usr/share/man/man8/ntpdc.8.xz

     * ------> FILES(-9) SIZE(+0.16%)
    ```
    
    ... but man pages remain in man1.
