[opensuse-factory] Cronie as default cron in Factory
Hi all! Next week I will move cronie[1] package to Factory, so it will replace old cron. If someone is against this step, please just write what's wrong. As I announced earlier, you could find Cronie in Base:System repo [2] there is also prepared wiki about known changes after switch to cronie [3] [1]https://fedorahosted.org/cronie/ [2]https://build.opensuse.org/package/show?package=cronie&project=Base%3ASystem [3]http://en.opensuse.org/Cron_replace#Differences_between_old_openSUSE.27s_cro... -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org
The crontab in there is basically a new setuid root program and the daemon too, so we need to audit it before 11.3 release.
I have opened an AUDIT-0 bug for it.
Is there any history to the daemon and tools? Where they forked from vixie cron?
Ciao, Marcus
Version 3 of Vixie cron was released in late 1993. Version 4.1 was renamed to ISC Cron and was released in January 2004 Fedora continue with own release 4.2 and 4.3 then they reorganize sources and clean up the package add anacron 2.3 and switch name to cronie v 1.0 ( this started sometime around Fedora 9) but upstart with planned features will probably replace cron,at and anacron at the end ... -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Thanks, Roman.
* fixes from Fedora comes to our distro * versioning, clean package (without old patches) currently we have ~20 patches, often in terrible state - it's the result of non existing upstream * cronie includes also anacron project and libaudit support -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

I found a mis-feature of cronie: If a user has a crontab entry that starts with a dash (meaning: don't log) the entire line is skipped. Existing crontab entries like that fail silently. If a user tries to create a crontab with a line like that, he gets an error: File /tmp/crontab.hA3Nld saved crontab: installing new crontab "/tmp/crontab.hA3Nld":5: bad option errors in crontab file, can't install. that doesn't explain anything.

That's because it is a system crontab. Disabling logging is permitted only for system crontabs and for the user with uid 0 (root). The old cron manual said: "If the uid of the owner is 0 (root), he can put a "-" as first character of a crontab entry. This will prevent cron from writing a syslog message about this command getting executed." But as you say, it worked even for unprivileged users' crontabs. (Probably a bug in old cron). As I see it, The current cronie behaviour is correct. Well, the manual page should mention the logging disabling ability as the old manual did. -- Vita Cizek

Didn't know it was a bug, as I found it useful.

It would be better if the feature could be disabled for certain users, with a list, such as the one allowed users. Linux machines are not always big multiuser installations, but also home, personal systems. No reason why a plain user should not be able to disable logging, if the root (same person) so wishes. - -- Cheers / Saludos, Carlos E. R.

Well. I would argue that "correct" in this case would be to not disable logging, but to still execute the command. Principle of least surprise. Maybe additionally log a warning that this is going to no longer work in after dec 31 2020 or something like that.

I meant "correct" as "cron was intended to behave like that". Submitted a fixed cron package: crontab.5 now includes: "If the uid of the owner is 0 (root), he can put a "-" as first character of a crontab entry. This will prevent cron from writing a syslog message about this command getting executed." Also, when an unprivileged user uses the dash, cron complains about incorrect minute, instead of an invalid option.

You're right. But as this behaviour was caused by a bug, I think it should be fixed. -- Vita Cizek

Then we should probably fix the crontabs during the update. The user hit by a regression will not care if this worked due to a bug before. it will probably be something like for i in /var/spool/cron/tabs/*; do case $i in */\*) continue ;; # no crontabs present */root) continue ;; # root is allowed *) sed -i 's/^-//' $i ;; esac done in %postin You'll have to do this for the next SLES anyway as such a regression will probably not be tolerated there ;) -- Stefan Seyfried "Dispatch war rocket Ajax to bring back his body!" -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

Yes, it should be fixed that cronie fails silently when it finds an entry with a dash. It should complain in the log and/or the email that the plain users can not use the dash; and ignore the dash and execute the entry, and log it. The current behavior of silently ignoring the entry is a bug. - -- Cheers / Saludos, Carlos E. R.

It doesn't fail silently, it complains to syslog with: "(CRON) ERROR (Only privileged user can disable logging)" I prefer Stefan's approach, cron will strip leading dashes from unprivileged users' crontabs during an update.

It fails silently. The syslog entry existed already, machine was using cron. Then machine is upgraded to oS 11.4, cron changed to cronie (not my decision), entry is no longer valid, it is not executed, nothing in syslog. Silence. It complains to syslog when the user edits the entry; but then remember that a plain user is not authorized to see what is in syslog (-rw-r----- root root), so to all purposes the failure is also silent.
I prefer Stefan's approach, cron will strip leading dashes from unprivileged users' crontabs during an update.
Too late. 11.4 was released.
The only case when a dash can slip to a user's crontab remains, when someone copies a crontab between different systems, but this is the user's fault and he should handle it himself.
You forget supported scenario of openSUSE upgrade. Not the user fault, but the packager fault. - -- Cheers / Saludos, Carlos E. R.

But 11.4 was released with a faulty cronie. That is how I found out.
Ugh. This is gonna need an update. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org/ iEYEARECAAYFAk3uLKYACgkQLPWxlyuTD7LKeACgpkoz3wbCxaj+2oBVCEMCBRHV SpgAoJpehhpYPuznEy81V2m0SMWpI7ml =o3Bl -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

I found a mis-feature of cronie:
If a user has a crontab entry that starts with a dash (meaning: don't log) the entire line is skipped. Existing crontab entries like that fail silently.
and the other is:
The old cron manual said: "If the uid of the owner is 0 (root), he can put a "-" as first character of a crontab entry. This will prevent cron from writing a syslog message about this command getting executed."
But as you say, it worked even for unprivileged users' crontabs. (Probably a bug in old cron).
