** Summary changed: - [SRU] Failed to build against linux-6.15 + [SRU] Failed to build against linux >= 6.15
** Description changed: [SRU Justification] [ Impact ] Failed to build against kernel v6.15-rc1. [ Test Plan ] - 0. Install mainline v6.15-rcX kernels from https://kernel.ubuntu.com/mainline + 0. Install kernels >= v6.15 + - mainline v6.15-rcX kernels from https://kernel.ubuntu.com/mainline, or + - linux-oem-6.17/noble 1. Install broadcom-sta-dkms from noble -proposed pocket 2. The dkms should rebuild itself against the running kernel automatically; if not rebuild them manually with: $ sudo dkms install --force broadcom-sta/6.30.223.271 -k $(uname -r) 3. Reboot to load the kernel module 4. The wl module should be loaded automatically and wireless lan should be usable as before. [ Where problems could occur ] This doesn't affect the rest part of the system, and it doesn't introduce functional changes. [ Other Info ] This affects series with kernels >= 6.15. Nominate Noble. - Kernels >= 6.15 will not be introduced in Plucky. - + Kernels >= 6.15 will not be introduced in Plucky. ========== original bug report ========== 1. EXTRA_*FLAGS has been deprecated for a while and is then removed in v6.15-rc1 commit e966ad0edd005 ("kbuild: remove EXTRA_*FLAGS support")， which results in following errors: # CC [M] src/wl/sys/wl_linux.o src/shared/linux_osl.c:23:10: fatal error: typedefs.h: No such file or directory 23 | #include <typedefs.h> | ^~~~~~~~~~~~ compilation terminated. make[4]: *** [/usr/src/linux-headers-6.15.0-9002-generic/scripts/Makefile.build:203: src/shared/linux_osl.o] Error 1 ＃ LD [M] wl.o CFG80211 API is prefered for this kernel version Using CFG80211 API Kernel architecture is X86_64 MODPOST Module.symvers ERROR: modpost: "wlc_get" [wl.ko] undefined!
