Как один баг чуть не убил марсоход за $400 млн, и почему везде важна конфигурация

3 января 2004 года марсоход «Спирит» коснулся поверхности Марса в кратере Гусева. Двадцать один день спустя он перестал отвечать на команды, ушёл в бутлуп и чуть не погиб от своей же операционки. О том, почему инженерам JPL этот инцидент до сих пор снится в кошмарах, как NASA дважды чуть не потеряло марсоходы из-за одной и той же ОС и почему везде важна правильная конфигурация — в статье.

@voided I'm intrigued - I did real-time multicast on #vxWorks using Ethernet MAC directly years ago.

@estherschindler I worked on the MIPS, PowerPC, and ARM architecture layers and BSPs for #VxWorks at #WindRiverSystems back from 1999‐2004, and then moved on to their embedded Linux kernel and BSPs, so if it is a general question, I might be able to help a little.... haven't kept up with it since then though.

Are there any active #VxWorks online communities? Where do those developers hang out? I have questions for them.

Anyone here knowledgeable about #VxWorks and #VxWin?

Please boost.

#VxWorks, a real-time operating system (RTOS) by Wind River, has been in development since 1980s. It is used in deterministic, real-time and safety-critical applications. Many well-known modern aircraft are running VxWorks on board. VxWorks has been heavily influenced by #Unix

@leonerd Spirit and Opportunity ran #VxWorks, and I don't think there's a perl port. I'd not be surprised if the follow-ups also run VxWorks. There's almost certainly perl code running on the control room side of things, of course, just because so many system maintenance tools are written in it.

@kenshirriff The first microprocessor I worked with that had a barrel shifter was at my first job at #Tektronix - port the #Magnolia #workstation (#Motorola 68000) V7 #UNIX first to 68010 but a few years later to 68EC040. The '40 had the barrel shifter. Man rotations were zippy. Later for #WindRiver I ported #VxWorks RTOS to #MIPS and #PowerPC chips. PPC bitfield ops were efficiently done with a bunch of rotate with mask instructions - IMO the pinnacle, the kitchen sink of embedded instructions.

We analysed the security of a #WindRiver #VxWorks (the operating system running also on NASA's Curiosity mars rover) embedded device and found a critical vulnerability in the #tarExtract function: https://www.pentagrid.ch/en/blog/wind-river-vxworks-tarextract-directory-traversal-vulnerability/ #itsecurity #infosec #pentesting #cisa #vxworks

As goes radation-hardened SoCs, so goes a segment the #embedded computer industry. I worked on the #VxWorks #RTOS port for PPC750+7400, the basis of #RAD750, and that was a major performance bump. The #SiFive X280 should enable a huge bump in smart on board processing for spacecraft. #riscv #powerpc
