kbuild: modinst: Fix build error when CONFIG_MODULE_SIG_KEY is a PKCS#11 URI

2023-02-09T10:28:11Z

[ Upstream commit 22e46f6480e83bcf49b6d5e6b66c81872c97a902 ] When CONFIG_MODULE_SIG_KEY is PKCS#11 URI (pkcs11:*), signing of modules fails: scripts/sign-file sha256 /.../linux/pkcs11:token=foo;object=bar;pin-value=1111 certs/signing_key.x509 /.../kernel/crypto/tcrypt.ko Usage: scripts/sign-file [-dp] [] scripts/sign-file -s [] First, we need to avoid adding the $(srctree)/ prefix to the URL. Second, since the kconfig string values no longer include quotes, we need to add them again when passing a PKCS#11 URI to sign-file. This avoids splitting by the shell if the URI contains semicolons.

Fix up more non-executable files marked executable

2023-02-01T07:34:49Z

[ Upstream commit c96618275234ad03d44eafe9f8844305bb44fda4 ] Joe found another DT file that shouldn't be executable, and that frustrated me enough that I went hunting with this script: git ls-files -s | grep '^100755' | cut -f2 | xargs grep -L '^#!' and that found another file that shouldn't have been marked executable either, despite being in the scripts directory. Maybe these two are the last ones at least for now. But I'm sure we'll be back in a few years, fixing things up again.

ftrace/scripts: Update the instructions for ftrace-bisect.sh

2023-02-01T07:34:37Z

commit 7ae4ba7195b1bac04a4210a499da9d8c63b0ba9c upstream. The instructions for the ftrace-bisect.sh script, which is used to find what function is being traced that is causing a kernel crash, and possibly a triple fault reboot, uses the old method. In 5.1, a new feature was added that let the user write in the index into available_filter_functions that maps to the function a user wants to set in set_ftrace_filter (or set_ftrace_notrace). This takes O(1) to set, as suppose to writing a function name, which takes O(n) (where n is the number of functions in available_filter_functions). The ftrace-bisect.sh requires setting half of the functions in available_filter_functions, which is O(n^2) using the name method to enable and can take several minutes to complete. The number method is O(n) which takes less than a second to complete. Using the number method for any kernel 5.1 and after is the proper way to do the bisect. Update the usage to reflect the new change, as well as using the /sys/kernel/tracing path instead of the obsolete debugfs path.

kbuild: Restore .version auto-increment behaviour for Debian packages

2022-11-17T08:51:45Z

Since 2df8220cc511 ("kbuild: build init/built-in.a just once"), generating Debian packages using 'make bindeb-pkg' results in packages that are stuck to the same .version, leading to unexpected behaviours (multiple packages with the same version). That's because the mkdebian script samples the build version before building the kernel, and forces the use of that version number for the actual build. Restore the previous behaviour by calling init/build-version instead of reading the .version file. This is likely to result in too many .version bumps, but this is what was happening before (although the bump was affecting builds made after the current one).

scripts/faddr2line: Fix regression in name resolution on ppc64le

2022-11-16T09:42:10Z

Commit 1d1a0e7c5100 ("scripts/faddr2line: Fix overlapping text section failures") can cause faddr2line to fail on ppc64le on some distributions, while it works fine on other distributions. The failure can be attributed to differences in the readelf output. $ ./scripts/faddr2line vmlinux find_busiest_group+0x00 no match for find_busiest_group+0x00 On ppc64le, readelf adds the localentry tag before the symbol name on some distributions, and adds the localentry tag after the symbol name on other distributions. This problem has been discussed previously: https://lore.kernel.org/bpf/20191211160133.GB4580@calabresa/ This problem can be overcome by filtering out the localentry tags in the readelf output. Similar fixes are already present in the kernel by way of the following commits: 1fd6cee127e2 ("libbpf: Fix VERSIONED_SYM_COUNT number parsing") aa915931ac3e ("libbpf: Fix readelf output parsing for Fedora") [jpoimboe: rework commit log] Fixes: 1d1a0e7c5100 ("scripts/faddr2line: Fix overlapping text section failures") Signed-off-by: Srikar Dronamraju Acked-by: Naveen N.

scripts/min-tool-version.sh: raise minimum clang version to 15.0.0 for s390

2022-11-09T17:41:16Z

Before version 15.0.0 llvm's integrated assembler may silently generate corrupted code on s390. See e.g. commit e9953b729b78 ("s390/boot: workaround llvm IAS bug") for further details. While there have been workarounds applied for all known existing locations, there is nothing that prevents that new code with problematic patterns will be added. Therefore raise the minimum clang version to 15.0.0. Note that llvm commit e547b04d5b2c ("[SystemZ] Bugfix for symbolic displacements."), which is included in 15.0.0, fixes the broken code generation.

kconfig: fix segmentation fault in menuconfig search

2022-11-02T08:32:05Z

Since commit d05377e184fc ("kconfig: Create links to main menu items in search"), menuconfig shows a jump key next to "Main menu" if the nearest visible parent is the rootmenu. If you press that jump key, menuconfig crashes with a segmentation fault. For example, do this: $ make ARCH=arm64 allnoconfig menuconfig Press '/' to search for the string "ACPI". Press '1' to choose "(1) Main menu". Then, menuconfig crashed with a segmentation fault. The following code in search_conf() conf(targets[i]->parent, targets[i]); results in NULL pointer dereference because targets[i] is the rootmenu, which does not have a parent. Commit d05377e184fc tried to fix the issue of top-level items not having a jump key, but adding the "Main menu" was not the right fix. The correct fix is to show the searched item itself. This fixes another weird behavior described in the comment block.
