Package: src:linux
Severity: wishlist

In the past, admins could get dmesg output without running it as root,
but this is no longer possible:

  * security,printk: Enable SECURITY_DMESG_RESTRICT, preventing non-root users
    reading the kernel log by default (sysctl: kernel.dmesg_restrict)

(in changelog.linux.gz). It is good that normal users cannot read
the kernel log, but for admins (typically users in the adm group,
who can already read /var/log/kern.log, thus have access to the same
information), this is a regression.

Note: "journalctl -b" also gives kernel logs (among other logs).

Since it is easy to change back to the old behaviour, this isn't a
significant regression.

Changing to a more sophisticated access policy could be done through
LSMs, perhaps.  But this is a feature request which would need to be
pursued upstream.
