Draft: module: Sync with upstream to v6.0-rc1
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2124824 Build: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=48122021 Tested: Compile and boot only
This series is based on tag modules-6.0-rc1 [1] which is similar to Linus' v6.0-rc1 yet excludes kunit related work. Please note, I plan to prepare a RHEL-only patch/or deviation from upstream: enabled Kconfig option CONFIG_MODULE_UNLOAD_TAINT_TRACKING to allow us to maintain a permanent record of each unloaded module that taints the kernel (see Linus' commit 99bd9956 "module: Introduce module unload taint tracking").

Aaron Tomlin (59): MAINTAINERS: Add Luis Chamberlain as modules maintainer module: fix clang CFI with MODULE_UNLOAD=n module: fix validate_section_offset() overflow bug on 64-bit module: change to print useful messages from elf_validity_check() livepatch: Avoid CPU hogging with cond_resched module: Remove outdated comment MAINTAINERS: Remove myself as modules maintainer module: add in-kernel support for decompressing MAINTAINERS: add mailing lists for kmod and modules kernel: Fix spelling mistake "compresser" -> "compressor" module: fix signature check failures when using in-kernel decompression Revert "module, async: async_synchronize_full() on module init iff async is used" module: fix building with sysfs disabled module: Move all into module/ module: Simple refactor in preparation for split module: Make internal.h and decompress.c more compliant module: Move livepatch support to a separate file module: Move latched RB-tree support to a separate file module: Move strict rwx support to a separate file module: Move extra signature support out of core code module: Move kmemleak support to a separate file module: Move kallsyms support into a separate file module: kallsyms: Fix suspicious rcu usage module: Move procfs support into a separate file module: Move sysfs support into a separate file module: Move kdb module related code out of main kdb code module: Move version support into a separate file module: Make module_enable_x() independent of CONFIG_ARCH_HAS_STRICT_MODULE_RWX module: Move module_enable_x() and frob_text() in strict_rwx.c module: Rework layout alignment to avoid BUG_ON()s module: Rename debug_align() as strict_align() module: Always have struct mod_tree_root module: Prepare for handling several RB trees module: Introduce data_layout module: Add CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC module: Remove module_addr_min and module_addr_max module: Make module_flags_taint() accept a module's taints bitmap and usable outside core code module: Move module_assert_mutex_or_preempt() to internal.h module: Introduce module unload taint tracking module: fix [e_shstrndx].sh_size=0 OOB access module: show disallowed symbol name for inherit_taint() module: do not pass opaque pointer for symbol search module: do not binary-search in __ksymtab_gpl if fsa->gplok is false module: merge check_exported_symbol() into find_exported_symbol_in_section() module: Fix prefix for module.sig_enforce module param modules: Fix corruption of /proc/kallsyms module: Fix selfAssignment cppcheck warning module: Fix "warning: variable 'exit' set but not used" module: kallsyms: Ensure preemption in add_kallsyms() with PREEMPT_RT module: Add support for default value for module async_probe module: Fix ERRORs reported by checkpatch.pl module: Increase readability of module_kallsyms_lookup_name() module: Use vzalloc() instead of vmalloc()/memset(0) module: Move module's Kconfig items in kernel/module/ module: Modify module_flags() to accept show_state argument module: Use strscpy() for last_unloaded_module module: Show the last unloaded module's taint flag(s) module: Replace kmap() with kmap_local_page() module: tracking: Keep a record of tainted unloaded modules only
