Full Changelog: 1.1.4...1.2.0

Write fully to shm

Write(2) to shared mem can return with a partial write. A loop is added to ensure that all bytes are written.

Pre-release for shm validation

Includes PR #13

More ref-counter corrections

Fix issue #12

Replaces 1.1.2 which should not be used.

Static ipu

Very small update to make a static build of the ipu utility.

Add fwmark debug command

Added;

> ./nfqlb fwmark -h
fwmark [--shm=] [--proto=tcp|udp|sctp] --src=addr:port --dst=addr:port
  Print hash and fwmark for the specified addresses for debug
  --shm= Shared memory. Required for fwmark printout 
  --proto= Protocol, tcp|udp|sctp. NOT specified -> address-only hash 
  --src= Source addr:port, e.g "[1000::80]:80" (required)
  --dst= Destination addr:port (required)

Good enough

This is not a quantum leap in quality and stability (actually this is the same as 0.11.0) but in spirit of semantic versioning setting a major version different from zero is a commitment not to make Non Backwards Compatible Changes (NBCs) without stepping the major release number. This include;

• Parameters to the nfqlb program (except trace, see below)
• The included library
• The format of shared memory data

NOT included;

• The trace interfaces
• The ipu program

These may change without stepping the major release number, but most likely not.

Add the ipu utility

The "ipu" utility is not really a load-balanacer program but comes in handy when setting up segmented test networks.

# ipu man
  NAME
    ipu - IP address format utility

  DESCRIPTION
    Interpretes a segmented ip-range in a 'double-dash' form, for example;
    '192.168.0.0/20/24' or '2000:2::/112/120' and prints a defined address.
    The first 'slot' holds the net and the second the host.

    makeip:

    --cidr=segmented-ip-range

    --net=number

    --host=number

    --subnet=1|2
        Append the subnet to the address printout. 1-net 2-host subnet number.

    --ipv6template=ipv6-address
        Print an IPv6 address from an IPv4 cidr by applying the mask and
        insert the IPv4 address in the last 32-bits.

  EXAMPLES

    # ipu makeip --cidr=10.0.0.0/16/24 --net=1 --host=2
    10.0.1.2

    # ipu makeip --cidr=10.0.0.0/16/24 --net=1 --host=2 --subnet=2
    10.0.1.2/24

    # ipu makeip --cidr=10.0.0.0/16/24 --net=1 --host=2 --subnet=2 --ipv6template=2000:1::0.0.0.0
    2000:1::a00:102/120

Trace flows

Trace flows can select par-packet traces with the same mechanism as normal traffic flows.

Fix memory leak in flow config

Also a "version" command is added. This version is updated for Ubuntu 22.04. There is a problem with static libmnl which enforces a local build.
