# Changelog
This project follows [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [v0.12.1] - 2022-06-01
* Changed
* The list of name servers that VintageNet uses when configuring the name
resolve is now available by running `VintageNet.get(["name_servers"])`.
## [v0.12.0] - 2022-04-27
This release has two potentially breaking changes:
1. Elixir 1.11 is now the minimum supported Elixir version.
2. `VintageNet.PropertyTable` has been extracted to its own library and is now
just `PropertyTable`. Most users did not use `VintageNet.PropertyTable`
directly, but if you did, you'll need to update the references.
* Changed
* Extract `VintageNet.PropertyTable` to its own library. Note that many
improvements were made to PropertyTable including renaming functions for
consistency and changing the events. Code was added to VintageNet to hide
these changes for now. Longer term, we'll be making things more consistent,
but the hope is that the PropertyTable changes are transparent to VintageNet
users in this release.
* Support specifying absolute paths to network configuration commands. While
this is not preferred, it's useful in some scenarios.
* Redact more kinds of secrets in `VintageNet.info`
## [v0.11.5] - 2022-02-18
* Changed
* Fix a no function clause exception in the InternetChecker that could happen
if no IP addresses were assigned to an interface.
## [v0.11.4] - 2021-12-20
* Changed
* Internet connectivity checks can now take domain names. Previously only IP
addresses were supported. This change lets you add your own servers to the
list since those servers may be more reliable indicators of Internet access
in highly firewalled locations. A section on this was added to the README.md
with an example.
## [v0.11.3] - 2021-11-18
* Changed
* Don't downgrade the connection status on DHCP renewals. Previously, if there
was a DHCP renewal, the connection status could go from "Internet-connected"
"LAN-connected". The logic was that IP address and router changes may make
the Internet unreachible. The new logic is to assume that the device is
still Internet-connected and let the connectivity checker downgrade the
status should it be necessary. This not only removes a status hiccup, but
also fixes a race between the connectivity checker upgrading the connection
and the DHCP notification degrading it.
* Improve the `VintageNet.info` error when the `:vintage_net` application
stops.
## [v0.11.2] - 2021-10-25
* Added
* Added `VintageNet.RouteManager.refresh_route_metrics/0` to recompute the
routing table metrics. This is useful if you're supplying your own
`:route_metric_fun` and something has changed to make it return a different
prioritization. Thanks to @LostKobrakai for this feature.
## [v0.11.1] - 2021-10-01
* Changed
* The DNS server ordering is more deterministic now. Global DNS servers are
guaranteed to be listed first and in the order specified. VintageNet will
also try to preserve the ordering of DNS servers learned through DHCP. This
isn't always possible, though. This fixes a hard-to-find error where an
a difference in DNS server orderings between to device locations led to
different behavior.
* Use `VintageNet.ConnectivityChecker.*` in VintageNet. The connectivity
checker module change was half made in `v0.11.0`, but the old module name
was kept in a couple places to avoid breaking unit tests in other VintageNet
libraries. Now it's completely converted. This doesn't affect runtime. Code
that references the previous names will still get deprecation warnings like
in `v0.11.0`.
## [v0.11.0] - 2021-08-19
This release should be a safe update for most users. Many routing table and
internet connectivity check modules were updated, but the changes were primarily
in private APIs.
* Added
* Support for detecting Internet connectivity on an interface passively by
watching tx and rx stats on TCP sockets. For example, if you have a
long-lived TCP connection (like for MQTT), the keepalive messages will
bump tx and rx counters that will let VintageNet skip testing the connection
for connectivity. This reduces traffic on metered connections.
* Support for completely overriding route metric calculation. You can now
specify a `:route_metric_fun` instead of using the `DefaultMetric`
calculator for determining which network interface preferences.
* VintageNet property change events now come with timestamps. These are useful
for computing state durations and other time-based stats for events.
* Removed
* Support for setting route prioritization order. This feature was more
limiting that it originally looked. The new `:route_metric_fun` is more
straightforward since it lets you explicitly specify orderings and lets
decisions be made based on more input data.
* Changed
* `VintageNet.Interface.InternetConnectivityChecker` is now
`VintageNet.Connectivity.InternetChecker`. Please update any references. Old
references will continue to work, but give a deprecation message at runtime.
## [v0.10.5] - 2021-07-12
This release only contains build system and hex package update. It doesn't
change any code and is a safe update.
## [v0.10.4] - 2021-07-06
* Fixed
* DHCP renewals would bounce connection status from :internet to :lan and back
even when the IP address, subnet, and default gateway didn't change. This
could cause a network connectivity hiccup that would happen every 24 hours
(a common DHCP lease time). A fix was added to assume internet connectivity
was maintained if the DHCP renewal didn't change IP parameters.
## [v0.10.3] - 2021-06-22
* Fixed
* Fix regression with tracking udhcpd lease notifications. Leases
notifications were being ignored, so if you were monitoring leases to see
who was connected, then you wouldn't see any connections without this fix.
Thanks to Jon Thacker for reporting this issue.
* Fix crashes when the application config is invalid. While the configurations
were incorrect and needed to be fixed, it was harder to debug than it should
have been. This release logs messages on invalid configs and carries on
bringing up left that's valid. Thanks to Matt Ludwigs for this fix.
## [v0.10.2] - 2021-05-20
This release officially removes support for Elixir 1.7 and Elixir 1.8. It turns
out that those versions wouldn't have worked in v0.10.0 due to a dependency that
was added.
* Added
* Add `VintageNet.reset_to_defaults/1` so that it's easy to reset a network
interface's configuration to what it would be if `VintageNet.configure` had
never been called. The previous "easy" way of doing this was to erase the
persisted configuration file and reboot.
* Clean up interface reachability handling (disconnected vs. lan-connected vs
internet-connected). There was an issue where the status was out of sync due
a bug in a technology implementation. This is harder to do now. IMPORTANT:
if you have a custom technology implementation, calling
`VintageNet.RouteManager.set_connection_status` is sufficient. You no
longer need to update the status property for your interface. This is not a
common need.
## [v0.10.1] - 2021-05-06
* Added
* There's now an `:additional_name_servers` global configuration key so that
it's possible to force name servers to always be in the list to use. For
example, if you don't trust that you'll always get good name servers from
DHCP, you can add a few public name servers to this list.
* `/etc/resolv.conf` now has nice comments on where configuration items come
from. Thanks to Connor Rigby for this idea and implementation.
## [v0.10.0] - 2021-04-06
This release is mostly backwards compatible. If you have created your own
VintageNet technology, you may need to update your unit tests. If you are an end
user of VintageNet, your code should continue to work unmodified.
* Added
* The Internet connectivity check logic now supports a list of IP addresses
instead of just one. The default has been updated to include major public
DNS providers. The code checks them in succession until one responds. See
`:internet_host_list` config key in the README.md if you need to change it.
* Only start `udhcpc`/`udhcpd` when the network interface is up. This removes
pointless attempts to get an IP address and their associated logs. It
reduces connection time for wired Ethernet but doesn't affect WiFI.
* Fixed
* Replace Crypto API calls that are no longer included with OTP 24.
* Redact SAE passwords
## [v0.9.3] - 2021-02-03
* Fixed
* Be more robust to `PowerManager.init/1` failures. While this function
shouldn't raise, the effect of it raising was particularly destructive to
VintageNet and took down networking.
* Update `gen_state_machine` dependency to let the 3.0.0 release be used.
## [v0.9.2] - 2020-10-10
* Fixed
* Handle missing commands as errors rather than raising. This makes it
a little easier test `vintage_net` and libraries that use it.
* Fixes `@doc` tag warnings during compile time
## [v0.9.1] - 2020-07-29
* Fixed
* This fixes an issue where system networking binaries were not being resolved
according to `vintage_net`'s view of the `PATH`. `vintage_net` looks in the
standard directories by default, but it's possible to restrict or add
locations.
## [v0.9.0] - 2021-07-24
This release contains improvements that will not affect you unless you are
using a custom `VintageNet.Technology` implementation.
* Added
* Add power management support. This adds support for powering on and off
network devices and also enables `VintageNet` to restart devices that are
not working (if allowed). See `VintageNet.PowerManager` for details.
* Changed
* Paths to networking programs like `wpa_supplicant` are no longer passed as
opts during configuration. I.e., `:bin_wpa_supplicant`, `:bin_ip`, etc. This
was not a generally useful feature since it wasn't possible to include all
possible programs. A future plan is to add support for verifying that
networking programs exist before trying to configure an interface. Programs
should be passed as strings now.
* Support for the `:busybox` hex package has been removed. This was useful
when networking programs were unavailable on a system, but all official
Nerves systems have included them for the past year and `:busybox` required
maintenance to keep working and up-to-date.
## [v0.8.0] - 2020-05-29
* Added
* [Breaking change for technology implementors] Decouple the network interface
name from the one a network technology uses. For example, cellular modems
can now have `vintage_net` wait for `wwan0` to appear before setting up a
PPP interface (like `ppp0`). All network technology implementations need to
be updated to provide `RawConfigs` that list the network interfaces they
need to start. This is hard to miss since you'll get a compile error if it
affects you.
* Deterministic interface naming support - If you have a device with multiple
network interfaces of the same type (e.g., multiple WiFi adapters) it is
possible for them to switch between being assigned `wlan0` and `wlan1`
under some conditions. This feature allows you to map their hardware
location to a name of your choosing. See the `README.md` for details.
* Add the "hw_path" property - For example, `{["interface", "eth0", "hw_path"], "/devices/platform/ocp/4a100000.ethernet"}`
* Fixed
* Stop network interface management `GenServers` before running the "down"
commands. This is most noticeable in reduced log noise on network hiccups
and device removals.
## [v0.7.9] - 2020-04-07
* Fixed
* Fix IP address being reported for PPP connections. Previously, it was the
remote end of the PPP connection rather than the local end.
* Fix missing IPv6 address reports. Depending on when IPv6 addresses were set
on network interfaces, they might not have been reported. Note that IPv6
isn't officially supported by VintageNet yet.
## [v0.7.8] - 2020-04-03
* Added
* Store an interface's configuration in the `["interface", ifname, "config"]`
property. This makes it possible to subscribe to configuration changes (like
any other property).
* Print out IP addresses with `VintageNet.info/0`
* Fixed
* Fixed `VintageNet.get_configuration/1` to return the configuration that will
be applied even if it's not the configuration that's currently applied.
The previous semantics would break code that made decisions based on the
current configurations.
## [v0.7.7] - 2020-03-23
* Added
* Added time-in-state to `VintageNet.info`. This lets you see if a connection
has bounced at a glance without digging through the logs.
## [v0.7.6] - 2020-03-18
* Fixed
* Ensure that `Technology.normalize/1` is always called. Previously, this
wasn't guaranteed, and it could result in a surprise when an unnormalized
configuration got saved.
* Remove duplicate resolv.conf entries on multi-homed devices
* Fix warnings found by Elixir 1.10
## [v0.7.5] - 2020-02-10
* Fixed
* Fix routing table error when configuring multiple interfaces of the same
type.
* Fix `VintageNet.info` for when it's called before `vintage_net` is loaded.
## [v0.7.4] - 2020-01-22
* Fixed
* Fix `VintageNet.info` crash when displaying AP mode configurations
* Save configurations using the `:sync` flag to reduce the chance that they're
lost on ungraceful power offs. I.e., people pulling the power cable after
device configuration.
## [v0.7.3] - 2020-01-21
* Added
* Scrub `VintageNet.info/0` output to avoid accidental disclosure of WiFi
credentials
* Support options to `deconfigure/2` to mirror those on `configure/2`
* Prefix `udhcpc` logs with interface to more easily blame problematic
networks
* Support IPv4 /32 subnets
* Various documentation fixes and improvements
## [v0.7.2] - 2019-12-20
* Bug fix
* Remove noisy log message introduced in v0.7.1
## [v0.7.1] - 2019-12-20
This release fixes an issue where the Internet-connectivity checking code could
crash. It was automatically restarted, but that had a side effect of delaying a
report that the device was connected AND breaking `mdns_lite`. Both the crash
and the restart issue were fixed. The `mdns_lite` side effect was due to its
multicast group membership being lost so this would affect other multicast-using
code.
* Fixed
* Fix `:timeout_value` crash in the `InternetConnectivityChecker`
* Force clear IPv4 addresses when the DHCP notifies a deconfig event. This
occurs on a restart and is quickly followed by a renew. However, if
applications don't see this, bounce and don't register their multicast
listeners on affected IPv4 address again, they'll lose the subscription.
* Added
* Added check for `nerves_network` and `nerves_init_gadget`. If your project
pulls these in, it will get a moderately friendly notice to remove them.
## [v0.7.0] - 2019-12-09
This release moves network technology implementations (WiFi, wired Ethernet,
etc.) into their own projects. This means that they can evolve at their own
pace. It also means that we're finally ready to support the
`VintageNet.Technology` behaviour as part of the public API so that VintageNet
users can add support for network technologies that we haven't gotten to yet.
IMPORTANT: This change is not backwards compatible. You will need to update
existing projects to bring in a new dependency. The runtime is backwards
compatible. I.e., If you have a networking configuration saved in VintageNet, it
will be updated on load. It won't be re-saved, so if you need to revert an
update, it will still work. The next save, though, will use the new naming.
If you're using `VintageNet.Technology.Gadget`, do the following:
1. Add `{:vintage_net_direct, "~> 0.7.0"}` to your `mix.exs` dependencies.
You'll notice that references to "gadget" have been replaced with the word
"direct". We think the new naming is more accurate.
2. Replace all references to `VintageNet.Technology.Gadget` in your code to
`VintageNetDirect`. Be aware of aliases and configuration.
3. If you passed options when configuring the network, the `:gadget` key is
now `:vintage_net_direct`. Most users don't pass options.
If you're using `VintageNet.Technology.Ethernet`, do the following:
1. Add `{:vintage_net_ethernet, "~> 0.7.0"}` to your `mix.exs` dependencies.
2. Replace all references to `VintageNet.Technology.Ethernet` in your code to
`VintageNetEthernet`. Be aware of aliases and configuration.
If you're using `VintageNet.Technology.WiFi`, do the following:
1. Add `{:vintage_net_wifi, "~> 0.7.0"}` to your `mix.exs` dependencies.
2. Replace all references to `VintageNet.Technology.WiFi` in your code to
`VintageNetWiFi`. Be aware of aliases and configuration. Also, the "F" is
capital.
3. The `:wifi` key in the network configuration is now `:vintage_net_wifi`.
## [v0.6.6] - 2019-12-01
* Fixed
* Fix warning from Dialyzer when making wild card subscriptions. Code was also
added to more thoroughly validate properties paths to raise on subtle issues
that won't do what the programmer intends.
* Added
* Added `VintageNet.match/1` to support "gets" on properties using wildcards.
## [v0.6.5] - 2019-11-22
* Added
* Support wild card subscriptions to properties. This makes it possible to
subscribe to things like `["interface", :_, "addresses"]` where the `:_`
indicates that any value in the second position should match. That
particular subscription would send a message whenever an IP address anywhere
gets added, changed, or removed.
## [v0.6.4] - 2019-10-31
* Added
* Added the `["interface", ifname, "eap_status"]` property for EAP
events. EAP is currently only supported on WiFi, but is anticipated for
wired Ethernet too.
## [v0.6.3] - 2019-10-28
This release renames the WiFi mode names. The old names still work so it's a
backwards compatible update. The new names are `:ap` and `:infrastructure`
instead of `:host` and `:client`. These names match the mode names in the IEEE
specifications and usage elsewhere.
* Added
* Support static IPv4 configurations for a default gateway and list of name
resolvers. See `:gateway` and `:name_servers` parameters.
* Support ad-hoc WiFi networking (IBSS mode)
## [v0.6.2] - 2019-10-11
* Added
* Support running a simple DNS server on an interface. This was added for WiFi
AP mode configuration and could be useful for other scenarios.
* Support DHCP server response options
* Support disabling configuration persistence on a per-call basis. This is for
temporary configurations where a reboot should not preserve the setting. For
example, `VintageNet.configure("wlan0", config, persist: false)`
## [v0.6.1] - 2019-10-02
* Added
* Add a `current_ap` property for WiFi interfaces so that programs can get
information about the currently associated access point
* Support running a DHCP server on wired Ethernet interfaces
* Expose `VintageNet.WiFi.WPA2.validate_passphrase/1` so that applications can
reuse the WiFI passphrase validation logic. This logic follows IEEE Std
802.11i-2004 and validates things like proper length and character set
## [v0.6.0] - 2019-09-25
IMPORTANT: This release contains a LOT of changes. VintageNet is still pre-1.0
and we're actively making API changes as we gain real world experience with it.
Please upgrade carefully.
* Changed
* All IP addresses are represented as tuples. You can still specify IP
addresses as strings, like "192.168.1.1", but it will be converted to tuple
form. When you `get` the configuration, you'll see IP addresses as tuples.
This means that if you save your configuration and revert to a previous
version of VintageNet, the settings won't work.
* WiFi network configuration is always under the `:networks` key. This was
inconsistent. Configuration normalization will update old saved
configurations.
* Support for the IPv4 broadcast IP address has been removed. Existing support
was incomplete and slightly confusing, so we decided to remove it for now.
* All IP address subnets are represented by their prefix length. For example,
255.255.255.0 is recorded as a subnet with prefix length 24. Configuration
normalization converts subnet masks to prefix length now.
* Added
* USB gadget support - See `VintageNet.Technology.Gadget`. It is highly likely
that we'll refactor USB gadget support to its own project in the future.
* Add `:verbose` key to configs for enabling debug messages from third party
applications. Currently `:verbose` controls debug output from
`wpa_supplicant`.
* Allow users to pass additional options to `MuonTrap` so that it's possible
to run network daemons in cgroups (among other things)
* Fixed
* Networking daemons should all be supervised now. For example, `udhcpc`
previously was started by `ifup` and under many conditions, it was possible
to get numerous instances started simultaneously. Plus failures weren't
detected.
* No more `killall` calls to cleanup state. This had prevented network
technologies from being used on multiple interfaces.
* No more `ifupdown`. This was very convenient for getting started, but has
numerous flaws. Search the Internet for rants. This was replaced with direct
calls to `ip link` and `ip addr` and adding network daemons to supervision
trees.
* Known issues
* Static IP addressing is still not implemented. It's only implemented enough
for WiFi AP mode and USB gadget mode to work. We hope to fix this soon.
* It's not possible to temporarily configure network settings. At the moment,
if persistence is enabled (the default), configuration updates are always
saved.
## [v0.5.1] - 2019-09-03
* Fixed
* Add missing PSK conversion when configuring multiple WiFi networks. This
fixes a bug where backup networks wouldn't connect.
* Added
* Don't poll WiFi networks that are configured for AP mode for Internet. They
will never have it.
* Reduce the number of calls to update routing tables. Previously they were
unnecessarily updated on DHCP failures due to timeouts. This also removes
quite a bit of noise from the log.
* Filter out interfaces with "Null" technologies on them from the configured
list. They really aren't configured so it was confusing to see them.
## [v0.5.0] - 2019-08-08
Backwards incompatible change: The WiFi access point property (e.g.,
["interfaces", "wlan0", "access_points"]) is now a simple list of access point
structs. It was formerly a map and code using this property will need to be
updated.
## [v0.4.1] - 2019-07-29
* Added
* Support run-time configuration of regulatory domain
* Error message improvement if build system is missing pkg-config
## [v0.4.0] - 2019-07-22
Build note: The fix to support AP scanning when in AP-mode (see below) required
pulling in libnl-3. All official Nerves systems have it installed since it is
required by the wpa_supplicant. If you're doing host builds on Linux, you'll
need to run `apt install libnl-genl-3-dev`.
* Added
* Report IP addresses in the interface properties. It's now possible to listen
for IP address changes on interfaces. IPv4 and IPv6 addresses are reported.
* Support scanning for WiFi networks when an WiFi module is in AP mode. This
lets you make WiFi configuration wizards. See the vintage_net_wizard
project.
* Add interface MAC addresses to the interface properties
* Fixed
* Some WiFi adapters didn't work in AP mode since their drivers didn't support
the P2P interface. Raspberry Pis all support the P2P interface, but some USB
WiFi dongles do not. The wpa_supplicant interface code was updated to use
fallback to the non-P2P interface in AP mode if it wasn't available.
## [v0.3.1] - 2019-06-28
* Added
* Add null persistence implementation for devices migrating from Nerves
Network that already have a persistence strategy in place
## [v0.3.0] - 2019-06-27
* Added
* Support the `busybox` hex.pm package to bring in networking support if not
present in the Nerves system image. This enables use with the minimal
official Nerves images.
* Add Unix domain socket interface to the `wpa_supplicant`. This enables
much faster scanning of WiFi networks and other things like collecting
attached clients when in AP-mode and pinging the supplicant to make sure
it's running.
* Log output of commandline-run applications so that error messages don't get
lost.
* Provide utilities for reporting WiFi signal strength as a percent to end
users.
* Fixed
* Support scanning WiFi access points with Unicode names (emoji, etc. in their
SSIDs)
* Allow internet connectivity pings to be missed 3 times in a row before
deciding that the internet isn't reachable. This avoids transients due to
the random dropped packet.
* Reduce externally visible transients due to internal GenServers crashing and
restarting - also addressed the crashes
* Support configure while configuring - let's you cancel a configuration that
takes a long time to apply and apply a new one
## [v0.2.4] - 2019-06-03
* Added
* Listen for interface additions and physical layer notifications so that
routing and status updates can be made much more quickly
* Add `lower_up` to the interface properties
## [v0.2.3] - 2019-05-29
* Fixed
* This release fixes supervision issues so that internal VintageNet crashes
can be recovered
* `VintageNet.get_configuration/1` works now
* `"available_interfaces"` is updated again
## [v0.2.2] - 2020-05-24
* Fixed
* Fix local LAN routing
## [v0.2.1] - 2020-05-16
* Added
* Expose summary status of whether the whole device is
disconnected, LAN-connected, or Internet-connected
## [v0.2.0] - 2020-05-15
* Added
* Support WiFi AP mode - see README.md for example
* Fixed
* Alway update local routes before default routes to avoid getting errors when
Linux detects a table entry that cannot be routed
