scripts/gdb: fix lx-timerlist for Python3

2023-05-11T14:17:37Z

commit 7362042f3556528e9e9b1eb5ce8d7a3a6331476b upstream. Below incompatibilities between Python2 and Python3 made lx-timerlist fail to run under Python3. o xrange() is replaced by range() in Python3 o bytes and str are different types in Python3 o the return value of Inferior.read_memory() is memoryview object in Python3 akpm: cc stable so that older kernels are properly debuggable under newer Python.

kbuild: use proper prefix for tarballs to fix rpm-pkg build error

2023-04-23T12:23:10Z

Since commit f8d94c4e403c ("kbuild: do not create intermediate *.tar for source tarballs"), 'make rpm-pkg' fails because the prefix of the source tarball is 'linux.tar/' instead of 'linux/'. $(basename $@) strips only '.gz' from the filename linux.tar.gz. You need to strip two suffixes from compressed tarballs and one suffix from uncompressed tarballs (for example 'perf-6.3.0.tar' generated by 'make perf-tar-src-pkg'). One tricky fix might be --prefix=$(firstword $(subst .tar, ,$@))/ but I think it is better to hard-code the prefix.

rust: fix regexp in scripts/is_rust_module.sh

2023-04-19T17:28:49Z

nm can use "R" or "r" to show read-only data sections, but scripts/is_rust_module.sh can only recognize "r", so with some versions of binutils it can fail to detect if a module is a Rust module or not. Right now we're using this script only to determine if we need to skip BTF generation (that is disabled globally if CONFIG_RUST is enabled), but it's still nice to fix this script to do the proper job. Moreover, with this patch applied I can also relax the constraint of "RUST depends on !DEBUG_INFO_BTF" and build a kernel with Rust and BTF enabled at the same time (of course BTF generation is still skipped for Rust modules). [ Miguel: The actual reason is likely to be a change on the Rust compiler between 1.61.0 and 1.62.0: echo '#[used] static S: () = ();' | rustup run 1.61.0 rustc --emit=obj --crate-type=lib - && nm rust_out.o echo '#[used] static S: () = ();' | rustup run 1.62.0 rustc --emit=obj --crate-type=lib - && nm rust_out.o Gives: 0000000000000000 r _ZN8rust_out1S17h48027ce0da975467E 0000000000000000 R _ZN8rust_out1S17h58e1f3d9c0e97cefE See https://godbolt.org/z/KE6jneoo4. ] Signed-off-by: Andrea Righi Reviewed-by: Vincenzo Palazzo Reviewed-by: Eric Curtin Reviewed-by: Martin Rodriguez Reboredo Signed-off-by: Miguel Ojeda
