# n-acd - IPv4 Address Conflict Detection
|
|
|
|
## CHANGES WITH 2:
|
|
|
|
* All public destructors now include a variant that returns `void`.
|
|
This was requested for easier integration with `glib` and friends.
|
|
Similar to the `cleanup` variants, these variants are denoted by a
|
|
single-character function-name suffix. E.g., `n_acd_freev()`
|
|
|
|
* A fallback to `CLOCK_MONOTONIC` is now provided in case
|
|
`CLOCK_BOOTTIME` is not supported by the kernel. Note that this is in
|
|
no way signalled through the API, so if timers should follow the
|
|
`BOOTTIME` rather than monotonic clock, a kernel with this clock is
|
|
required.
|
|
|
|
* The `c-sundry` dependency is no longer needed.
|
|
|
|
* The `transport` configuration property is now mandatory for
|
|
`n_acd_new()`. It defaulted to `ETHERNET` before, by mistake.
|
|
|
|
* In-source documentation for the public API is now provided.

## CHANGES WITH 1:
|
|
|
|
* Initial release of n-acd. This project implements the IPv4 Address
|
|
Conflict Detection standard as defined in RFC-5227. The state machine
|
|
is implemented in a shared library and provides a stable ISO-C11 API.
|
|
The implementation is linux-only and relies heavily on the API
|
|
behavior of recent linux kernel releases.
|
|
|
|
* Compared to the pre-releases, this release supports many parallel
|
|
probes on a single n-acd context. This reduces the number of
|
|
allocated network resources to O(1), based on the number of running
|
|
parallel probes.
|
|
|
|
* The n-acd project is now dual-licensed: ASL-2.0 and LGPL-2.1+
