ld: vmlinux.o: in function `patch_retpoline': alternative.c:(.text+0x3b6f1): undefined reference to `module_alloc' make[2]: *** [scripts/Makefile.vmlinux:37: vmlinux] Error 1
We see this build error in 6.6.91-rc2 tag.
What is odd about your .config? Have a link to it? I can't duplicate it here on my builds.
So this is a config where CONFIG_MODULES is unset(!=y) -- with that we could reproduce it on defconfig + disabling CONFIG_MODULES as well.
Key is the combination of CONFIG_MODULES=n with CONFIG_MITIGATION_ITS=y.
Ah, this is due to the change in its_alloc() for 6.6.y and 6.1.y by the call to module_alloc() instead of execmem_alloc() in the backport of 872df34d7c51 ("x86/its: Use dynamic thunks for indirect branches").
Pawan, any hints on what should be done here instead?
thanks,
