mips: always link byteswap helpers into decompressor

2021-07-20T14:05:58+00:00

[ Upstream commit cddc40f5617e53f97ef019d5b29c1bd6cbb031ec ] My series to clean up the unaligned access implementation across architectures caused some mips randconfig builds to fail with: mips64-linux-ld: arch/mips/boot/compressed/decompress.o: in function `decompress_kernel': decompress.c:(.text.decompress_kernel+0x54): undefined reference to `__bswapsi2' It turns out that this problem has already been fixed for the XZ decompressor but now it also shows up in (at least) LZO and LZ4. From my analysis I concluded that the compiler could always have emitted those calls, but the different implementation allowed it to make otherwise better decisions about not inlining the byteswap, which results in the link error when the out-of-line code is missing. While it could be addressed by adding it to the two decompressor implementations that are known to be affected, but as this only adds 112 bytes to the kernel, the safer choice is to always add them.

MIPS: compressed: fix build with enabled UBSAN

2021-03-25T08:04:12+00:00

[ Upstream commit fc4cac4cfc437659ce445c3c47b807e1cc625b66 ] Commit 1e35918ad9d1 ("MIPS: Enable Undefined Behavior Sanitizer UBSAN") added a possibility to build the entire kernel with UBSAN instrumentation for MIPS, with the exception for VDSO. However, self-extracting head wasn't been added to exceptions, so this occurs: mips-alpine-linux-musl-ld: arch/mips/boot/compressed/decompress.o: in function `FSE_buildDTable_wksp': decompress.c:(.text.FSE_buildDTable_wksp+0x278): undefined reference to `__ubsan_handle_shift_out_of_bounds' mips-alpine-linux-musl-ld: decompress.c:(.text.FSE_buildDTable_wksp+0x2a8): undefined reference to `__ubsan_handle_shift_out_of_bounds' mips-alpine-linux-musl-ld: decompress.c:(.text.FSE_buildDTable_wksp+0x2c4): undefined reference to `__ubsan_handle_shift_out_of_bounds' mips-alpine-linux-musl-ld: arch/mips/boot/compressed/decompress.o: decompress.c:(.text.FSE_buildDTable_raw+0x9c): more undefined references to `__ubsan_handle_shift_out_of_bounds' follow Add UBSAN_SANITIZE := n to mips/boot/compressed/Makefile to exclude it from instrumentation scope and fix this issue.
