Hi Mark, I want to ask you a question regarding elf internals. How to calculate a symbol's file offset (which is kernel uprobe expects) in an elf (executable or shared object)?
Some real world use case use either section header like libbpf: https://github.com/libbpf/libbpf/blob/374036c9f1cdfe2a8df98d9d6a53c34fd02de14b/src/elf.c#L259-L270 Or use program header like BCC: https://github.com/iovisor/bcc/blob/82f9d1cb633aa3b4ebcbbc5d8b809f48d3dfa222/src/cc/bcc_syms.cc#L767-L775 Which is correct ? Is there a unified way to get the file offset of a symbol ? Thanks. -- Hengqi
