I'm currently working on the following (may be outdated):
* [http://bugzilla.gnome.org/show_bug.cgi?id=683173 New platform interaction framework]
* NetworkManager upstream QA, bug triaging (component general) and bits of documentation
* Virtual device support (bridging, bonding, etc)
* Fixes and improvements for getaddrinfo() in glibc
* Configuration formats
* [http://bugzilla.gnome.org/show_bug.cgi?id=663602 Building NetworkManager on any distribution without unnecessary hassle]
* IPv4 and IPv6 automatic configuration improvements (NDP and DHCP)
* Various NetworkManager fixups and cleanups (like anyone else in the team)
* Various linux networking improvements
When working with linux networking, the following projects cause me headache:
* NetworkManager itself: I need to test NM in a virtual environment with bridges. These are not supported in the current release. I hope to make the next release mature enough to support its own development.
* Kernel: The kernel IPv6 networking layer is somewhat unmanagable. The rtnetlink interface doesn't provide enough funcionality to support IPv6 networking.
* GLIBC: The <code>getaddrinfo()</code> function doesn't work properly and is not supported in nsswitch.conf. It breaks whenever my development machine happens to be on an IPv4-only network.
* nss-mdns (Avahi nsswitch plugin): Can't implement link-local name resolution because of the above problem in GLIBC.
* IETF networking standards: For some reasons many IPv6-related standards have serious design flaws that prevent them from working properly.

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 2012 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.

    • 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.
