[$] Indirect calls in BPF

Date:
Mon, 21 Apr 2025 20:27:59 +0000

Description:
Anton Protopopov kicked off the BPF track on
the second day of the 2025 Linux Storage, Filesystem,
Memory-Management, and BPF Summit with a discussion about permitting
indirect calls in BPF. He also spoke about his continuing work on static keys 
, a topic which is related because the implementation of indirect
jumps and static keys in the verifier use some of the same mechanisms for
tracking indirect control-flow.
Although some design work remains to be done, it may soon be
possible to make indirect calls in BPF without any extra work compared to 
normal
C.
