About

After learning a bit of programming, I was attracted by the networking world. I got from petty Pascal/C++ projects through web development using ugly PHP and later Python, to a freelancing work with most of the projects in server administration, network equipment configuration and a bit of programming. Most people in the business know me from my conference talks and articles.

One of my conference talk brought me an offer from Red Hat, which I joined in May 2012 to work on NetworkManager. I was already a Fedora user and package maintainer at that time. Since August 2013 I'm no longer working as a regular NetworkManager developer (staying an upstream contributor, though). Even before that I tried to put my hands on a number of other projects via bug reports, tests and code. I'm also interested in various network-related standards and especially bugs and bad assumptions in IETF documents.

Upstream contributions

• NetworkManager
  • Building on any distribution
  • Virtual device support (bridging/bonding, with others)
  • Valgrind and code coverage support for tests
  • Separate platform interaction module (nm-platform, with Dan Winship)
    • Refactored NetworkManager's bridging/bonding/vlan configuration
    • Refactored NetworkManager's IPv4/IPv6 configuration
  • Userspace IPv6 autoconfiguration (nm-rdisc/libndp, with Jiří Pírko)
    • Getting IPv6 autoconf features on par with IPv4
    • Avoiding loads of kernel IPv6 bugs and design flaws
  • Runtime (non-persistent) configuration support (with Dan Winship and Dan Williams)
  • A lot of bug triaging

Bug tracking/reporting

• avahi
  • Missing for IPv6 link-local addresses.
  • IPv6 disabled by default.
  • Problems with duplicates in discovery.
• glibc
  • The getaddrinfo() support is very complicated while not giving correct results in many cases.
• kernel
  • Network configuration is a real pain.
  • Kernel IPv6 autoconfiguration is only designed for trivial use cases and is very buggy.
• libnl
  • Most of the advanced stuff is very buggy.
