[$] LLVM improvements for BPF verification

Date:
Mon, 27 May 2024 17:04:36 +0000

Description:
Alan Jowett gave a remote presentation at the 2024 Linux Storage,
Filesystem, Memory Management, and BPF Summit about what features could be
added to LLVM to make writing BPF programs easier. While there is nothing 
specific
to LLVM about BPF code (and the next session in the track was led by GCC
developer Jos Marchesi about better support for that compiler), LLVM is 
currently the most
common way to turn C code into BPF bytecode. That translation, however, runs
into problems when the BPF verifier cannot understand the code LLVM's
optimizations produce.
