This makes it possible to only start IPFS when needed. So a user’s
IPFS daemon only starts when they actually use it.
A few important warnings though:
- This probably shouldn’t be mixed with services.ipfs.autoMount
since you want /ipfs and /ipns aren’t activated like this
- ipfs.socket assumes that you are using ports 5001 and 8080 for the
API and gateway respectively. We could do some parsing to figure
out what is in apiAddress and gatewayAddress, but that’s kind of
difficult given the nonstandard address format.
- Apparently? this doesn’t work with the --api commands used in the tests.
Of course you can always start automatically with startWhenNeeded =
false, or just running ‘systemctl start ipfs.service’.
Tested with the following test (modified from tests/ipfs.nix):
import ./make-test-python.nix ({ pkgs, ...} : {
name = "ipfs";
nodes.machine = { ... }: {
services.ipfs = {
enable = true;
startWhenNeeded = true;
};
};
testScript = ''
start_all()
machine.wait_until_succeeds("ipfs id")
ipfs_hash = machine.succeed("echo fnord | ipfs add | awk '{ print $2 }'")
machine.succeed(f"ipfs cat /ipfs/{ipfs_hash.strip()} | grep fnord")
'';
})

Update nixos/modules/services/network-filesystems/ipfs.nix

Previously we had three services for different config flavors. This is
confusing because only one instance of IPFS can run on a host / port
combination at once. So move all into ipfs.service, which contains the
configuration specified in services.ipfs.
Also remove the env wrapper and just use systemd env configuration.
The default `undervolt` package does not accept floating point numbers for any of its numeric
arguments. This also mentions in what units are the values expressed.
The setgid is currently required for offline enqueuing, and
unfortunately smtpctl is currently not split from sendmail so there's
little running around it.
The OC_PASS environment variable can be used to create a user with
`occ user:add --password-from-env`. It is currently not possible to
use the `nextcloud-occ` to "non-interactively" create a user since
this variable is ignored by sudo.
This switches the unit to Restart=on-failure and switches the CPU policy
to fifo (the daemon tries to do that itself, but is denied permission).
Also add the package to $PATH to be able to use fs_cli easily.
It's pbPort, and it's also a connection string, meaning
listen-on-localhost is also possible. Provide an alias for the old
option name, so old configs still work.
This patch was done by curro:
The generated /etc/pam.d/* service files invoke the pam_systemd.so
session module before pam_mount.so, if both are enabled (e.g. via
security.pam.services.foo.startSession and
security.pam.services.foo.pamMount respectively).
This doesn't work in the most common scenario where the user's home
directory is stored in a pam-mounted encrypted volume (because systemd
will fail to access the user's systemd configuration).
This fixes a regression from 993baa587c which requires
networking.hostName to be a valid DNS label [0].
Unfortunately we missed the fact that the hostnames may also be empty,
if the user wants to obtain it from a DHCP server. This is even required
by a few modules/images (e.g. Amazon EC2, Azure, and Google Compute).

xchg is advertised as a bidirectional exchange dir, but file content
transfer from host to VM fails due to caching:
If a file is read in the VM and then modified on the host, subsequent
re-reads in the VM can yield old, cached data.
This is caused by the use of 9p's cache=loose mode that is explicitly
meant for read-only mounts.
9p doesn't provide any suitable cache modes, so fix this by disabling
caching.
Also, remove a now unnecessary sync in the test driver.
This effectively disables nscd's built-in hosts cache, which turns out
to be erratic in some cases.
We only use nscd these days as a more ABI-neutral NSS dispatcher
mechanism.
Local caching should still be possible with local resolvers in
/etc/resolv.conf (via the `dns` NSS module), or without local resolvers
via systemd-networkd (via the `resolve` nss module)
We don't set enable-cache to no due to
https://github.com/NixOS/nixpkgs/pull/50316#discussion_r241035226.
Refactor the systemd service definition for the haproxy reverse proxy,
using the upstream systemd service definition. This allows the service
to be reloaded on changes, preserving existing server state, and adds
some hardening options.
These syncs have the goal to transfer host filesystem changes to the VM,
but they have no effect because 1) syncing in the VM can't possibly pull
in host data and 2) 9p is accessing the host filesystem on the cached
layer anyways, so even syncing on the host would have no effect in the
VM.
The `networking.interfaces.<name?>.proxyARP` option previously mentioned it would also enable IPv6 forwarding and `proxy_ndp`.
However, the `proxy_ndp` option was never actually set (the non-existing `net.ipv6.conf.proxy_arp` sysctl was set
instead). In addition `proxy_ndp` also needs individual entries for each ip to proxy for.
Proxy ARP and Proxy NDP are two different concepts, and enabling the latter
should be a conscious decision.
This commit removes the broken NDP support, and disables explicitly
enabling IPv6 forwarding (which is the default in most cases anyways)
Fixes#62339.
NixOS currently has issues with setting the FQDN of a system in a way
where standard tools work. In order to help with experimentation and
avoid regressions, add a test that checks that the hostname is
reported as the user wanted it to be.

This fixes the output of "hostname --fqdn" (previously the domain name
was not appended). Additionally it's now possible to use the FQDN.
This works by unconditionally adding two entries to /etc/hosts:
127.0.0.1 localhost
::1 localhost
These are the first two entries and therefore gethostbyaddr() will
always resolve "127.0.0.1" and "::1" back to "localhost" [0].
This works because nscd (or rather the nss-files module) returns the
first matching row from /etc/hosts (and ignores the rest).
The FQDN and hostname entries are appended later to /etc/hosts, e.g.:
127.0.0.2 nixos-unstable.test.tld nixos-unstable
::1 nixos-unstable.test.tld nixos-unstable
Note: We use 127.0.0.2 here to follow nss-myhostname (systemd) as close
as possible. This has the advantage that 127.0.0.2 can be resolved back
to the FQDN but also the drawback that applications that only listen to
127.0.0.1 (and not additionally ::1) cannot be reached via the FQDN.
If you would like this to work you can use the following configuration:
```nix
networking.hosts."127.0.0.1" = [
"${config.networking.hostName}.${config.networking.domain}"
config.networking.hostName
];
```
Therefore gethostbyname() resolves "nixos-unstable" to the FQDN
(canonical name): "nixos-unstable.test.tld".
Advantages over the previous behaviour:
- The FQDN will now also be resolved correctly (the entry was missing).
- E.g. the command "hostname --fqdn" will now work as expected.
Drawbacks:
- Overrides entries form the DNS (an issue if e.g. $FQDN should resolve
to the public IP address instead of 127.0.0.1)
- Note: This was already partly an issue as there's an entry for
$HOSTNAME (without the domain part) that resolves to
127.0.1.1 (!= 127.0.0.1).
- Unknown (could potentially cause other unexpected issues, but special
care was taken).
[0]: Some applications do apparently depend on this behaviour (see
c578924) and this is typically the expected behaviour.
