Merge tag 'modules-6.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux
Pull modules updates from Luis Chamberlain:
"Nothing exciting at all for modules for v6.3.
The biggest change is just the change of INSTALL_MOD_DIR from "extra"
to "updates" which I found lingered for ages for no good reason while
testing the CXL mock driver [0].
The CXL mock driver has no kconfig integration and requires building
an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash.
All this can obviously be fixed by integrating kconfig semantics into
such test module, however that's not desirable by the maintainer, and
so sensible defaults must be used to ensure a default "make
modules_install" will suffice for most distros which do not have a
file like /etc/depmod.d/dist.conf with something like `search updates
extra built-in`.
Since most distros rely on kmod and since its inception the "updates"
directory is always in the search path it makes more sense to use that
than the "extra" which only *some* RH based systems rely on.
All this stuff has been on linux-next for a while"

Since apply_relocate_add() requires access to a module's section headers, symbol table, and relocation section indices, Elf information is preserved for livepatch modules and is made accessible by the module loader through -module->klp_info, which is a klp_modinfo struct. When a livepatch module loads, -this struct is filled in by the module loader. Its fields are documented below:: - - struct klp_modinfo { - Elf_Ehdr hdr; /* Elf header */ - Elf_Shdr *sechdrs; /* Section header table */ - char *secstrings; /* String table for the section headers */ - unsigned int symndx; /* The symbol table section index */ - }; +module->klp_info, which is a :c:type:`klp_modinfo` struct.
