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. -----BEGIN PGP SIGNATURE----- iQFPBAABCgA5FiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmaWYxwbHG1hc2FtaS5o aXJhbWF0c3VAZ21haWwuY29tAAoJENv7B78FKz8bsUgH/3JcSzDZujQWCZ1f4fJn QecvTFSYcCl6ck8+/3wm4EsgeCXIFOyPnoPc7k2Gm+l6Dlk1DKGV6wV4tuKFUq9X 9mplcwoVA0Ln+EX9zv9v4s99yUGxcU9xjgC9XT7J52SvqYncPIi6dR0Z9wlJBmyd Bx3cZk+wSzCYaoqYngI2fKlzsEcYgDIP999fQPRi0HGzNZujc4xeJyjCTC/48yWO 9kreRQq6wFdgRQTwMcR/fKPDKIGZQCU8jkXv5crVV5K3rNaBcwBmCJJMP8PzPU0V UQ0+8RZK+Qk8SBwXcMNVRqm/efTderob4IYxP8OBe5wjAIE7+vu8r6sqwxRIS54M Cyg= =DRSr -----END PGP SIGNATURE----- Merge tag 'probes-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace 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.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
