Hi!
The Netfilter project presents:
nftables 0.3
This release contains bug fixes, syntax cleanups, new features, support
for all new features contained in the recent 3.15 kernel release.
Syntax changes
==============
* More compact syntax for the queue action, eg.
nft add rule test input queue num 1
You can also express the multiqueue as a range, followed by options.
nft add rule test input queue num 1-3 bypass fanout
Or just simply the options:
nft add rule test input queue bypass
New features
============
* Match input and output bridge interface name through 'meta ibriport'
and 'meta obriport', e.g.
nft add rule bridge filter input meta ibriport br0 counter
* netlink event monitor, to monitor ruleset events, set changes, etc.
The most simple way to monitor updates is to run:
nft monitor
* New transaction infrastructure - fully atomic updates for all
object available in the upcoming 3.16.
Bug fixes
=========
* Fix crash when nftables / nfnetlink support is not present in the kernel.
* Fix crash when using multi-line command in interative mode, eg.
nft -i
nft> list \
.... table filter
* Fix wrong packet and bytes counters when the rule-set is reloaded.
* Fix wrong output in chain priorities
type route hook output priority -1
^^
* Fix assertion when using non-equal comparison, eg.
nft add rule filter input ip protocol != icmp counter
^^
* Range inversions, eg.
nft add rule filter input != 192.168.0.1-192.168.0.10
^^
* Fix 'meta iiftype ether'.
* Fix the udplite selector, due to missing code in the tokenizer.
Ongoing works
=============
There are several open fronts in terms of development:
* Full logging support for all the supported families (ip, ip6, arp,
bridge and inet).
* Masquerading support.
* Better reject support, which allows you to indicate the explicit reject
reason.
* JSON/XML import.
* reverse set lookups, eg.
ip saddr != { 192.168.0.1, 192.168.0.10, 192.168.0.11 }
^^
* more new meta selectors, packet type (unicast, multicast and broadcast),
cpu, physical interface, realm, etc.
* support for concatenations - multidimensional exact matches in O(1) types
* set selection - automatic selection of the optimal set
implementation.
Resources
