Pull probes updates from Masami Hiramatsu:
"Uprobes:
- x86/shstk: Make return uprobe work with shadow stack
- Add uretprobe syscall which speeds up the uretprobe 10-30% faster.
This syscall is automatically used from user-space trampolines
which are generated by the uretprobe. If this syscall is used by
normal user program, it will cause SIGILL. Note that this is
currently only implemented on x86_64.
(This also has two fixes for adjusting the syscall number to avoid
conflict with new *attrat syscalls.)
- uprobes/perf: fix user stack traces in the presence of pending
uretprobe. This corrects the uretprobe's trampoline address in the
stacktrace with correct return address
- selftests/x86: Add a return uprobe with shadow stack test
- selftests/bpf: Add uretprobe syscall related tests.
- test case for register integrity check
- test case with register changing case
- test case for uretprobe syscall without uprobes (expected to fail)
- test case for uretprobe with shadow stack
- selftests/bpf: add test validating uprobe/uretprobe stack traces
- MAINTAINERS: Add uprobes entry. This does not specify the tree but
to clarify who maintains and reviews the uprobes
Kprobes:
- tracing/kprobes: Test case cleanups.
Replace redundant WARN_ON_ONCE() + pr_warn() with WARN_ONCE() and
remove unnecessary code from selftest
- tracing/kprobes: Add symbol counting check when module loads.
This checks the uniqueness of the probed symbol on modules. The
same check has already done for kernel symbols
(This also has a fix for build error with CONFIG_MODULES=n)
Cleanup:
- Add MODULE_DESCRIPTION() macros for fprobe and kprobe examples"
