modpost: Add '.ltext' and '.ltext.*' to TEXT_SECTIONS

2024-02-23T08:51:39Z

commit 397586506c3da005b9333ce5947ad01e8018a3be upstream. After the linked LLVM change, building ARCH=um defconfig results in a segmentation fault in modpost. Prior to commit a23e7584ecf3 ("modpost: unify 'sym' and 'to' in default_mismatch_handler()"), there was a warning: WARNING: modpost: vmlinux.o(__ex_table+0x88): Section mismatch in reference to the .ltext:(unknown) WARNING: modpost: The relocation at __ex_table+0x88 references section ".ltext" which is not in the list of authorized sections. If you're adding a new section and/or if this reference is valid, add ".ltext" to the list of authorized sections to jump to on fault. This can be achieved by adding ".ltext" to OTHER_TEXT_SECTIONS in scripts/mod/modpost.c. The linked LLVM change moves global objects to the '.ltext' (and '.ltext.*' with '-ffunction-sections') sections with '-mcmodel=large', which ARCH=um uses. These sections should be handled just as '.text' and '.text.*' are, so add them to TEXT_SECTIONS.

modpost: trim leading spaces when processing source files list

2024-02-23T08:51:34Z

[ Upstream commit 5d9a16b2a4d9e8fa028892ded43f6501bc2969e5 ] get_line() does not trim the leading spaces, but the parse_source_files() expects to get lines with source files paths where the first space occurs after the file path.

modpost: fix section mismatch message for RELA

2023-11-16T11:14:44Z

The section mismatch check prints a bogus symbol name on some architectures. [test code] #include int __initdata foo; int get_foo(void) { return foo; } If you compile it with GCC for riscv or loongarch, modpost will show an incorrect symbol name: WARNING: modpost: vmlinux: section mismatch in reference: get_foo+0x8 (section: .text) -> done (section: .init.data) To get the correct symbol address, the st_value must be added. This issue has never been noticed since commit 93684d3b8062 ("kbuild: include symbol names in section mismatch warnings") presumably because st_value becomes zero on most architectures when the referenced symbol is looked up. It is not true for riscv or loongarch, at least. With this fix, modpost will show the correct symbol name: WARNING: modpost: vmlinux: section mismatch in reference: get_foo+0x8 (section: .text) -> foo (section: .init.data) Signed-off-by: Masahiro Yamada Reviewed-by: Nick Desaulniers

Pull staging driver updates from Greg KH: "Here is the big set of staging driver updates for 6.7-rc1. A bit bigger than 6.6 this time around, as it coincided with the Outreachy and mentorship application process, so we got a bunch of new developers sending in their first changes, which is nice to see. Also in here is a removal of the qlge ethernet driver, and the rtl8192u wireless driver. Both of these were very old and no one was maintaining them, the wireless driver removal was due to no one using it anymore, and no hardware to be found, and is part of a larger effort to remove unused and old wifi drivers from the system. The qlge ethernet driver did have one user pop up after it was dropped, and we are working with the network mainainers to figure out what tree it will come back in from and who will be responsible for it, and if it really is being used or not. Odds are it will show up in a network subsystem pull request after -rc1 is out, but we aren't sure yet. Other smaller changes in here are: - Lots of vc04_services work by Umang to clean up the mess created by the rpi developers long ago, bringing it almost into good enough shape to get out of staging, hopefully next major release, it's getting close. - rtl8192e variable cleanups and removal of unused code and structures - vme_user coding style cleanups - other small coding style cleanups to lots of the staging drivers - octeon typedef removals, and then last-minute revert when it was found to break the build in some configurations (it's a hard driver to build properly, none of the normal automated testing catches it.)
