I'm Abdul Wasey. I work on networks and firmware, which in practice means I spend my time somewhere between a bootloader and a routing daemon.
At Quantum Networks I work on secure boot for OpenWrt-based access points on Qualcomm platforms: verified boot in U-Boot, the signing pipeline behind it, and the recovery work for when a board no longer boots. Before that I was at Tata Communications bonding WAN links with Multipath TCP on OpenMPTCProuter, and I spent three years running infrastructure for IRIS at NITK, where I'm finishing a B.Tech in Metallurgical and Materials Engineering, which is not what I ended up doing.
Lately I've been working in the Linux data path. xdp-bfd moves BFD failure detection into XDP so it keeps its timing under load that makes userspace daemons flap. Building it meant reading a lot of FRR's BFD daemon, which turned into sixteen merged fixes. Running Multipath TCP over real links has also turned up a couple of fixes in the Linux kernel's MPTCP code.
Most of what I use, I host. Mail, DNS, passwords, chat, media, and this site all run on a two-node cluster in my flat, and a lot of what I know about networking came from breaking it. I write things up when they seem useful, moderate r/dockerCE, and speak at FOSS United meetups now and then.
What I like working on
- Packet processing in the kernel, and measuring whether it actually works.
- Boot chains and signing, so a device only runs what it's supposed to.
- Bugs that only show up in a packet capture.
- Running my own stuff, and fixing it when I break it.
