Release notes are available at https://www.openssh.com/txt/release-7.5.
Mostly a bugfix release, no major backwards-incompatible changes.
Remove deprecated `UsePrivilegeSeparation` option,
which is now mandatory.
AFAICT, this issue only occurs when sshd is socket-activated. It turns
out that the preStart script's stdout and stderr are connected to the
socket, not just the main command's. So explicitly connect stderr to
the journal and redirect stdout to stderr.
This reverts commit 1a74eedd07. It
breaks NixOps, which expects that
rm -f /etc/ssh/ssh_host_ed25519_key*
systemctl restart sshd
cat /etc/ssh/ssh_host_ed25519_key.pub
works.
This option was initially added to make it easier to use an
up-to-date list, but now that we always use an up-to-date list
from upstream, there's no point to the option.
From now on, you can either use a resolver listed by dnscrypt
upstream or a custom resolver.
Removes tcpOnly and ephemeralKeys: reifying them as nixos
options adds little beyond improved discoverability. Until
17.09 we'll automatically translate these options into extraArgs
for convenience.
Unless reifying an option is necessary for conditional
computation or greatly simplifies configuration/reduces risk of
misconfiguration, it should go into extraArgs instead.
Newer versions of DNSCrypt proxy *can* cache lookups (via
plugin); make the wording more neutral wrt. why one might want
to run the proxy in a forwarding setup.
It'd be better to do the update as an unprivileged user; for
now, we do our best to minimize the surface available. We
filter mount syscalls to prevent the process from undoing the fs
isolation.
Resolve download.dnscrypt.org using hostip with a bootstrap
resolver (hard-coded to Google Public DNS for now), to ensure
that we can get an up-to-date resolver list without working name
service lookups. This makes us more robust to the upstream
resolver list getting out of date and other DNS configuration
problems.
We use the curl --resolver switch to allow https cert validation
(we'd need to do --insecure if using just the ip addr). Note
that we don't rely on https for security but it's nice to have
it ...
Use mkMerge to make the code a little more ergonomic and easier
to follow (to my eyes, anyway ...). Also take the opportunity
to do some minor cleanups & tweaks, but no functional changes.
Set `networking.networkmanager.wifi.macAddress` or `networking.networkmanager.ethernet.macAddress`
to one of these values to change your macAddress.
* "XX:XX:XX:XX:XX:XX": set the MAC address of the interface.
* "permanent": use the permanent MAC address of the device.
* "preserve": don’t change the MAC address of the device upon activation.
* "random": generate a randomized value upon each connect.
* "stable": generate a stable, hashed MAC address.
See https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/ for more information
reason:
- We currently have an open discussion regarding a more modular
firewall (https://github.com/NixOS/nixpkgs/issues/23181) and
leaving null makes future extension easier.
- the current default might not cover all use cases (different ssh port)
and might break setups, if applied blindly
When dhcpcd instead of networkd is used, the network-online.target behaved
the same as network.target, resulting in broken services that need a working
network connectivity when being started.
This commit makes dhcpcd wait for a lease and makes it wanted by
network-online.target. In turn, network-online.target is now wanted by
multi-user.target, so it will be activated at every boot.
