Guile Netlink 1.0 released

[Julien Lepiller]

Hi!

I'm proud to announce the first release of Guile Netlink!

  git clone https://git.lepiller.eu/git/guile-netlink
  cd guile-netlink
  git checkout 1.0 # or 29ff43368f1cc2d10a7e5f09dc9f80f85582d6ee
  git tag -v 1.0

The 'git tag -v' command check the authenticity of your checkout. You
may need to retrieve the signing key first:

  gpg --keyserver pool.sks-keyservers.net \
      --recv-keys 1EFB09091F17D28CCBF9B13A53D457B2D636EE82

Guile Netlink provides three components:

- A helper library for implementing netlink protocols
- An implementation of rtnetlink, one of the netlink protocols. It is
  used to query and alter the state of the network stack in Linux.
- A high-level API implemented on top of rtnetlink and inspired by
  iproute2's commands

Here are a few examples (most of which will only work as root and will
really modify your network), extracted from the manual:

  ;; same as "ip l add v0p0 type veth peer v0p1"
  (link-add "v0p0" "veth" #:type-args '((peer . "v0p1")))

  ;; same as "ip a add 192.0.2.15/24 dev enp1s0
  (addr-add "enp1s0" "192.0.2.15/24")
  (addr-add "enp1s0" "2001:db8::1a4c/64" #:ipv6? #t)

  ;; removing the previous addresses, as in "ip a del 192.0.2.15/24 dev
  ;; enp1s0"
  (addr-del "enp1s0" "192.0.2.15/24")
  (addr-del "enp1s0" "2001:db8::1a4c/64" #:ipv6? #t)

  ;; same as "ip a" or "ip addr show"
  (addr-show)

  ;; same as "ip r add default via 192.0.2.1 dev enp1s0"
  (route-add "default" #:device "enp1s0" #:via "192.0.2.1")
  ;; same as "ip r add 192.0.2.0/24 dev enp1s0 src 192.0.2.15"
  (route-add "192.0.2.0/24" #:device "enp1s0" #:src "192.0.2.15")

Hopefully, the high-level API can be used on Linux to replace our
current implementation of container networking and static networking
service type.

You will find the complete documentation online at
https://git.lepiller.eu/guile-netlink/manual, the code is available at
https://git.lepiller.eu/guile-netlink (note that the clone URL is
different, see above) and you can report any issue, patch and ideas to
me, by email.

Hope you'll enjoy!

Julien
