Wed, 19 Jun 2024 14:15:03 +0000

Description:
Andrii Nakryiko led a session at
the 2024 Linux Storage,
Filesystem, Memory Management, and BPF Summit giving
a look into the APIs for capturing stack traces
using BPF, and how the APIs could be made more useful. BPF programs can capture the
current stack trace of a running process, including the portion in the kernel during execution of a system call, which can be useful for diagnosing performance problems, among other things. But there are substantial problems with
the existing API.
