There's a kernel bug that causes cookies to be misplaced and the reason we did not catch this with this test is that we provide bpf_fentry_test* functions already sorted by name. Shuffling function bpf_fentry_test2 deeper in the list and keeping the current cookie values as before will trigger the bug. The kernel fix is coming in following changes.

We want to store the resolved address on the same index as the symbol string, because that's the user (bpf kprobe link) code assumption. Also making sure we don't store duplicates that might be present in kallsyms. Acked-by: Song Liu <[email protected]> Acked-by: Steven Rostedt (Google) <[email protected]> Fixes: bed0d9a ("ftrace: Add ftrace_lookup_symbols function") Signed-off-by: Jiri Olsa <[email protected]>
When user specifies symbols and cookies for kprobe_multi link interface it's very likely the cookies will be misplaced and returned to wrong functions (via get_attach_cookie helper). The reason is that to resolve the provided functions we sort them before passing them to ftrace_lookup_symbols, but we do not do the same sort on the cookie values. Fixing this by using sort_r function with custom swap callback that swaps cookie values as well.

Add JIT support for the load_acquire and store_release instructions. The
implementation is similar to the kernel where:
load_acquire => plain load -> lwsync
store_release => lwsync -> plain store
