2024-09-05docs: rust: include other expressions in conditional compilation sectionMiguel Ojeda
Expand the conditional compilation section to explain how to support other expressions, such as testing whether `RUSTC_VERSION` is at least a given version, which requires a numerical comparison that Rust's `cfg` predicates do not support (yet?).

2024-09-05kbuild: rust: replace proc macros dependency on `core.o` with the version textMiguel Ojeda
With the `RUSTC_VERSION_TEXT` rebuild support in place, now proc macros can depend on that instead of `core.o`. This means that both the `core` and `macros` crates can be built in parallel, and that touching `core.o` does not trigger a rebuild of the proc macros. This could be accomplished using the same approach as for `core` (i.e. depending directly on `include/config/RUSTC_VERSION_TEXT`). However, that is considered an implementation detail [1], and thus it is best to avoid it. Instead, let fixdep find a string that we explicitly write down in the source code for this purpose (like it is done for `include/linux/compiler-version.h`), which we can easily do (unlike for `core`) since this is our own source code.

2024-09-05kbuild: rust: rebuild if the version text changesMiguel Ojeda
Now that `RUSTC_VERSION_TEXT` exists, use it to rebuild `core` when the version text changes (which in turn will trigger a rebuild of all the kernel Rust code). This also applies to proc macros (which only work with the `rustc` that compiled them), via the already existing dependency on `core.o`. That is cleaned up in the next commit. However, this does not cover host programs written in Rust, which is the same case in the C side. This is accomplished by referencing directly the generated file, instead of using the `fixdep` header trick, since we cannot change the Rust standard library sources. This is not too much of a burden, since it only needs to be done for `core`.

2024-09-05kbuild: rust: re-run Kconfig if the version text changesMiguel Ojeda
Re-run Kconfig if we detect the Rust compiler has changed via the version text, like it is done for C. Unlike C, and unlike `RUSTC_VERSION`, the `RUSTC_VERSION_TEXT` is kept under `depends on RUST`, since it should not be needed unless `RUST` is enabled.

2024-09-05kbuild: rust: add `CONFIG_RUSTC_VERSION`Miguel Ojeda
Now that we support several Rust versions, introduce `CONFIG_RUSTC_VERSION` so that it can be used in Kconfig to enable and disable configuration options based on the `rustc` version. The approach taken resembles `pahole`'s -- see commit 613fe1692377 ("kbuild: Add CONFIG_PAHOLE_VERSION"), i.e. a simple version parsing without trying to identify several kinds of compilers, since so far there is only one (`rustc`). However, unlike `pahole`'s, we also print a zero if executing failed for any reason, rather than checking if the command is found and executable (which still leaves things like a file that exists and is executable, but e.g. is built for another platform [1]). An equivalent approach to the one here was also submitted for `pahole` [2].

In zh_CN part of translations.pdf, there are several ASCII-art diagrams whose vertical lines look sometimes jagged. This is due to the interference between default settings of xeCJK and fancyvrb (employed in sphinxVerbatim env), where extra space is inserted between a latin char and a non-latin char when they are next to each other (i.e., no explicit white space). This issue can be suppressed by invoking \CJKsetecglue{} at the beginning of every sphinxVerbatim enviornment. \AtBeginEnvironment, provided by the etoolbox package, is useful in this case.

2024-09-05selftests/bpf: Rename fallback in bpf_dctcp to avoid naming conflictPu Lehui
Recently, when compiling bpf selftests on RV64, the following compilation failure occurred: progs/bpf_dctcp.c:29:21: error: redefinition of 'fallback' as different kind of symbol 29 | volatile const char fallback[TCP_CA_NAME_MAX]; | ^ /workspace/tools/testing/selftests/bpf/tools/include/vmlinux.h:86812:15: note: previous definition is here 86812 | typedef u32 (*fallback)(u32, const unsigned char *, size_t); The reason is that the `fallback` symbol has been defined in arch/riscv/lib/crc32.c, which will cause symbol conflicts when vmlinux.h is included in bpf_dctcp. Let we rename `fallback` string to `fallback_cc` in bpf_dctcp to fix this compilation failure.

The $(let ...) function is only supported by GNU Make version 4.4 [0] and above, otherwise the following exception file or directory will be generated: tools/testing/selftests/bpfFEATURE-DUMP.selftests tools/testing/selftests/bpffeature/ Considering that the GNU Make version of most Linux distributions is lower than 4.4, let us adapt the corresponding logic to it.

2024-09-05bpf: Fix uprobe multi pid filter checkJiri Olsa
Uprobe multi link does its own process (thread leader) filtering before running the bpf program by comparing task's vm pointers. But as Oleg pointed out there can be processes sharing the vm (CLONE_VM), so we can't just compare task->vm pointers, but instead we need to use same_thread_group call.
