powerpc/modules: Fix crashes by adding CONFIG_RELOCATABLE to vermagic # # If you build the kernel with CONFIG_RELOCATABLE=n, then install the # modules, rebuild the kernel with CONFIG_RELOCATABLE=y and leave the # old modules installed, we crash something like: # # Unable to handle kernel paging request for data at address 0xd000000018d66cef # Faulting instruction address: 0xc0000000021ddd08 # Oops: Kernel access of bad area, sig: 11 [#1] # Modules linked in: x_tables autofs4 # CPU: 2 PID: 1 Comm: systemd Not tainted 4.16.0-rc6-gcc_ubuntu_le-g99fec39 #1 # ... # NIP

SyS_finit_module+0x110/0x140 # system_call+0x58/0x6c # # This happens because since commit 71810db27c1c ("modversions: treat # symbol CRCs as 32 bit quantities"), a relocatable kernel encodes and # handles symbol CRCs differently from a non-relocatable kernel. # # Although it's possible we could try and detect this situation and # handle it, it's much more robust to simply make the state of # CONFIG_RELOCATABLE part of the module vermagic. # # Fixes: 71810db27c1c ("modversions: treat symbol CRCs as 32 bit quantities") # Signed-off-by: Michael Ellerman # <
