Subject: [PATCH v4 0/2] x86: bpf unwinder fixes
Date: Thu, 27 Jun 2019 20:50:45 -0500	[thread overview]
Message-ID: <cover.1561685471.git.jpoimboe@redhat.com> (raw)

Here's the last fix along with its objtool dependency.

For testing I verified that a WARN() in ___bpf_prog_run() now gives a
clean stack trace.

v4: 
- Redesigned the jump table detection mechanism.  Instead of requiring
  the jump table to have a magic name, place it in a special section.

- The other two fixes from v3 have been merged into -tip.

Josh Poimboeuf (2):
  objtool: Add support for C jump tables
  bpf: Fix ORC unwinding in non-JIT BPF code
