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 2 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 be failed).
. 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.
