ELF Nightmares: GOTs, PLTs, and Relocations Oh My by John Baldwin

Mapping abstract symbol names in source code to concrete addresses at runtime requires cooperation between the compiler, static linker, and runtime loader. This talk will talk about some of the practices and data structures used for this task including ELF relocations, Global Offset Tables and Procedure Linkage Tables. Depending on time, it may also cover some more advanced topics such as initialization functions ("ifuncs").

$Encouraging & enabling SMEs (small to medium enterprises) to contribute to BSD development -TomSmyth - Making use of the force multiplier of many hands make light work. - Tom Smyth talks about his experience using BSD as a small business owner. - Tom further explores the positive experience of supporting developers to achieve discrete real improvements in OpenBSD and related projects. - How small business can contribute to and shape BSD development. - Ideas about aggregating the resources of multiple small businesses to achieve an outcome that each small business individually could not afford - SMEs can reap 100% of the benefit by just committing a fraction of the cost. Can many hands and many pockets contribute to sustainable code development without burdening the projects that will have to maintain the code on an ongoing basis? This talk is an AMA format and propose a 15-20 minute talk and 30 minute Q & A session afterwards.$
