2023-01-26x86/boot/compressed: prefer cc-option for CFLAGS additionsNick Desaulniers
as-option tests new options using KBUILD_CFLAGS, which causes problems when using as-option to update KBUILD_AFLAGS because many compiler options are not valid assembler options. This will be fixed in a follow up patch. Before doing so, move the assembler test for -Wa,-mrelax-relocations=no from using as-option to cc-option.

2023-01-22fixdep: do not parse *.rlib, *.rmeta, *.soMasahiro Yamada
fixdep is designed only for parsing text files. read_file() appends a terminating null byte ('\0') and parse_config_file() calls strstr() to search for CONFIG options. rustc outputs *.rlib, *.rmeta, *.so to dep-info. fixdep needs them in the dependency, but there is no point in parsing such binary files.

2023-01-22fixdep: avoid parsing the same file over againMasahiro Yamada
The dep files (*.d files) emitted by C compilers usually contain the deduplicated list of included files. One exceptional case is when a header is included by the -include command line option, and also by #include directive. For example, the top Makefile adds the command line option, "-include $(srctree)/include/linux/kconfig.h". You do not need to include <linux/kconfig.h> in every source file. In fact, include/linux/kconfig.h is listed twice in many .*.cmd files due to include/linux/xarray.h having "#include <linux/kconfig.h>". I did not fix that since it is a small redundancy. However, this is more annoying for rustc. rustc emits the dependency for each emission type. For example, cmd_rustc_library emits dep-info, obj, and metadata. So, the emitted *.d file contains the dependency for those 3 targets, which makes fixdep parse the same file 3 times. $ grep rust/alloc/raw_vec.rs rust/.alloc.o.cmd rust/alloc/raw_vec.rs \ rust/alloc/raw_vec.rs \ rust/alloc/raw_vec.rs \ To skip the second parsing, this commit adds a hash table for parsed files, just like we did for CONFIG options.

2023-01-22fixdep: parse Makefile more correctly to handle comments etc.Masahiro Yamada
fixdep parses dependency files (*.d) emitted by the compiler. *.d files are Makefiles describing the dependencies of the main source file. fixdep understands minimal Makefile syntax. It works well enough for GCC and Clang, but not for rustc. This commit improves the parser a little more for better processing comments, escape sequences, etc. My main motivation is to drop comments. rustc may output comments (e.g. env-dep). Currentyly, rustc build rules invoke sed to remove comments, but it is more efficient to do it in fixdep.

2023-01-22kbuild: specify output names separately for each emission type from rustcMasahiro Yamada
In Kbuild, two different rules must not write to the same file, but it happens when compiling rust source files. For example, set CONFIG_SAMPLE_RUST_MINIMAL=m and run the following: $ make -j$(nproc) samples/rust/rust_minimal.o samples/rust/rust_minimal.rsi \ samples/rust/rust_minimal.s samples/rust/rust_minimal.ll [snip] RUSTC [M] samples/rust/rust_minimal.o RUSTC [M] samples/rust/rust_minimal.rsi RUSTC [M] samples/rust/rust_minimal.s RUSTC [M] samples/rust/rust_minimal.ll mv: cannot stat 'samples/rust/rust_minimal.d': No such file or directory make[3]: *** [scripts/Makefile.build:334: samples/rust/rust_minimal.ll] Error 1 make[3]: *** Waiting for unfinished jobs.... mv: cannot stat 'samples/rust/rust_minimal.d': No such file or directory make[3]: *** [scripts/Makefile.build:309: samples/rust/rust_minimal.o] Error 1 mv: cannot stat 'samples/rust/rust_minimal.d': No such file or directory make[3]: *** [scripts/Makefile.build:326: samples/rust/rust_minimal.s] Error 1 make[2]: *** [scripts/Makefile.build:504: samples/rust] Error 2 make[1]: *** [scripts/Makefile.build:504: samples] Error 2 make: *** [Makefile:2008: .] Error 2 The reason for the error is that 4 threads running in parallel renames the same file, samples/rust/rust_minimal.d. This does not happen when compiling C or assembly files because -Wp,-MMD,$(depfile) explicitly specifies the dependency filepath. $(depfile) is a unique path for each target. Currently, rustc is only given --out-dir and --emit=<list-of-types> So, all the rust build rules output the dep-info into the default <CRATE_NAME>.d, which causes the path conflict. Fortunately, the --emit option is able to specify the output path individually, with the form --emit=<type>=<path>. Add --emit=dep-info=$(depfile) to the common part. Also, remove the redundant --out-dir because the output path is specified for each type. The code gets much cleaner because we do not need to rename *.d files.

The cmd-check macro compares $(cmd_$@) and $(cmd_$1), but a pitfall is that you cannot use cmd_<target> as the variable name for the command. For example, the following code will not work in the top Makefile or ./Kbuild. quiet_cmd_foo = GEN $@ cmd_foo = touch $@ targets += foo foo: FORCE $(call if_changed,foo) In this case, both $@ and $1 are expanded to 'foo', so $(cmd_check) is always empty.

2023-01-22kbuild: print short log in addition to the whole command with V=1Masahiro Yamada
"make V=1" prints the whole command instead of the short log, but I think it is nicer to print both so that you can easily spot the build rule of your interest. This commit changes V=1 to print the short log (the line starts with '#'), followed by the full log. In parallel builds, the short/full logs from the same build rule may be interspersed. If you want to avoid it, please add -Otarget option. Kbuild will never set it by default because Make would buffer the logs and lose the escape sequences. (Modern compilers print warnings and errors in color, but only when they write to a terminal.) This is also a preparation for supporting V=12 because V=2 appends the reason for rebuilding to the short log.

2023-01-21ext4: deal with legacy signed xattr name hash valuesLinus Torvalds
We potentially have old hashes of the xattr names generated on systems with signed 'char' types. Now that everybody uses '-funsigned-char', those hashes will no longer match. This only happens if you use xattrs names that have the high bit set, which probably doesn't happen in practice, but the xfstest generic/454 shows it. Instead of adding a new "signed xattr hash filesystem" bit and having to deal with all the possible combinations, just calculate the hash both ways if the first one fails, and always generate new hashes with the proper unsigned char version.

2023-01-21prlimit: do_prlimit needs to have a speculation checkGreg Kroah-Hartman
do_prlimit() adds the user-controlled resource value to a pointer that will subsequently be dereferenced. In order to help prevent this codepath from being used as a spectre "gadget" a barrier needs to be added after checking the range.

2023-01-20io_uring/poll: don't reissue in case of poll race on multishot requestJens Axboe
A previous commit fixed a poll race that can occur, but it's only applicable for multishot requests. For a multishot request, we can safely ignore a spurious wakeup, as we never leave the waitqueue to begin with. A blunt reissue of a multishot armed request can cause us to leak a buffer, if they are ring provided. While this seems like a bug in itself, it's not really defined behavior to reissue a multishot request directly. It's less efficient to do so as well, and not required to rearm anything like it is for singleshot poll requests.
