Hello Fedora devels and users,
more than three years ago, the same topic started discussion if we

mostly in flames and in the removal of the dependency on tcp_wrappers
from systemd. But it was quite agreed that it is considered as a
security layer for some users, if they use it correctly, or something
that is or should be replaced by firewalls.
So can we discuss it now once more without the affiliation to
The fact is that we still do not have any other replacement except
firewalls. But do we need one?
The complete removal of the package is probably not a wise step, even
though we can not find tcp_wrappers in recent SuSE anymore . It is
still available in Arch  without other tools depending on it. To
fair, Debian  is still building tools (for example openssh) with a
build-time support for it.
My primary concern is OpenSSH, which upstream dropped support for
tcp_wrappers three years ago (late 2014)  and since then we are
maintaining one more downstream patch. But this effort should be
coordinated among other components to simplify the transition for
who insist on using it (using tcpd).
Removing the dependency will also allow us to trim the default
install for few more Kb.
If there will be no significant drawbacks, I will progress with
a system wide change for Fedora 28 and I will pull the maintainers of
other tolls using libwrap into the round and discussion.
In Fedora 26, there is over 50 packages using tcp_wrappers as a build-
Since I'm listed twice in there...
With my packages and the situation with build time options I take the
position of enable as much as possible since our users don't get to pick
their compilation options.
However tcp_wrappers is a legacy thing that no longer belongs in today's
I have no objection to a flag day in F28 development and dropping the build
option at some point, preferably before the thing that is no longer an
alpha ;) ... ie way before beta.
As for downstream ... well we're Fedora. If Red Hat want it still in RHEL8
that's up to them and they can maintain the downstream patches in their
