Well actually there has been a patchset, no? I think it's just that
noone really pushed hard enough for it (or long enough for that matter).

Thanks to both.

Done; will watch for results :-)

Hi,

Yes, this is normal and as pointed out already, can be tweaked with
dmesg_restrict.

There was some interest a while back in implementing a logging
namespace, which would solve this cleanly, but it's never been enough
of a priority for anyone to actually do the kernel work for it.

I'd say it's a "normal, bad default".

You can fix it by adding this to your sysctl config file:

kernel.dmesg_restrict = 1

[lxc-users] kernel messages appear in containers?

2019-02-02 Thread Richard Hector
Hi all,

I've noticed that some log messages that really belong to the host (like
those from monthly RAID checks, for example) can appear in arbitrary
containers instead - so they're spread all over the place.

Is that normal/fixable?

Cheers,
Richard
