2019-05-02powerpc/mm/radix: Make Radix require HUGETLB_PAGEMichael Ellerman
commit 8adddf349fda0d3de2f6bb41ddf838cbf36a8ad2 upstream. Joel reported weird crashes using skiroot_defconfig, in his case we jumped into an NX page: kernel tried to execute exec-protected page (c000000002bff4f0) - exploit attempt? (uid: 0) BUG: Unable to handle kernel instruction fetch Faulting instruction address: 0xc000000002bff4f0 Looking at the disassembly, we had simply branched to that address: c000000000c001bc 49fff335 bl c000000002bff4f0 But that didn't match the original kernel image: c000000000c001bc 4bfff335 bl c000000000bff4f0 <kobject_get+0x8> When STRICT_KERNEL_RWX is enabled, and we're using the radix MMU, we call radix__change_memory_range() late in boot to change page protections. We do that both to mark rodata read only and also to mark init text no-execute. That involves walking the kernel page tables, and clearing _PAGE_WRITE or _PAGE_EXEC respectively. With radix we may use hugepages for the linear mapping, so the code in radix__change_memory_range() uses eg. pmd_huge() to test if it has found a huge mapping, and if so it stops the page table walk and changes the PMD permissions. However if the kernel is built without HUGETLBFS support, pmd_huge() is just a #define that always returns 0. That causes the code in radix__change_memory_range() to incorrectly interpret the PMD value as a pointer to a PTE page rather than as a PTE at the PMD level. We can see this using `dv` in xmon which also uses pmd_huge(): 0:mon> dv c000000000000000 pgd @ 0xc000000001740000 pgdp @ 0xc000000001740000 = 0x80000000ffffb009 pudp @ 0xc0000000ffffb000 = 0x80000000ffffa009 pmdp @ 0xc0000000ffffa000 = 0xc00000000000018f <- this is a PTE ptep @ 0xc000000000000100 = 0xa64bb17da64ab07d <- kernel text The end result is we treat the value at 0xc000000000000100 as a PTE and clear _PAGE_WRITE or _PAGE_EXEC, potentially corrupting the code at that address. In Joel's specific case we cleared the sign bit in the offset of the branch, causing a backward branch to turn into a forward branch which caused us to branch into a non-executable page. However the exact nature of the crash depends on kernel version, compiler version, and other factors. We need to fix radix__change_memory_range() to not use accessors that depend on HUGETLBFS, but we also have radix memory hotplug code that uses pmd_huge() etc that will also need fixing. So for now just disallow the broken combination of Radix with HUGETLBFS disabled. The only defconfig we have that is affected is skiroot_defconfig, so turn on HUGETLBFS there so that it still gets Radix.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Notable changes: - A fix for a bug in our page table fragment allocator, where a page table page could be freed and reallocated for something else while still in use, leading to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for a powerpc only refcount. - Fixes to our pkey support. Several are user-visible changes, but bring us in to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer for reporting many of these. - A series to improve the hvc driver & related OPAL console code, which have been seen to cause hardlockups at times. The hvc driver changes in particular have been in linux-next for ~month. - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y. - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use anywhere other than as a paper weight. - An optimised memcmp implementation using Power7-or-later VMX instructions - Support for barrier_nospec on some NXP CPUs. - Support for flushing the count cache on context switch on some IBM CPUs (controlled by firmware), as a Spectre v2 mitigation. - A series to enhance the information we print on unhandled signals to bring it into line with other arches, including showing the offending VMA and dumping the instructions around the fault.

2018-07-24powerpc: Add ppc32_allmodconfig defconfig targetMichael Ellerman
Because the allmodconfig logic just sets every symbol to M or Y, it has the effect of always generating a 64-bit config, because CONFIG_PPC64 becomes Y. So to make it easier for folks to test 32-bit code, provide a phony defconfig target that generates a 32-bit allmodconfig. The 32-bit port has several mutually exclusive CPU types, we choose the Book3S variants as that's what the help text in Kconfig says is most common.

2017-08-28powerpc/configs: Update for CONFIG_INPUT_MOUSEDEV=nMichael Ellerman
In commit 73d8ef76006b ("Input: mousedev - stop offering PS/2 to userspace by default") the symbol INPUT_MOUSEDEV went from being 'default y' to 'default n' (implied). That means we no longer need to explicitly disable it in our defconfigs. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2017-08-28powerpc/configs: Drop removed CONFIG_LOGFSMichael Ellerman
In commit 1d0fd57a50aa ("logfs: remove from tree"), logfs was removed from the tree, so we can drop it from our defconfigs. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
2017-08-28powerpc/configs: Turn CONFIG_R128 back in pmac32_defconfigMichael Ellerman
In commit d92d9c3a1448 ("drm: hide legacy drivers with CONFIG_DRM_LEGACY") CONFIG_R128 was moved behind CONFIG_DRM_LEGACY meaning it stopped being enabled by pmac32_defconfig. Although no one has noticed, given this is basically a legacy platform, it seems anyone who is using it probably still wants this driver. So turn it back on for now.

2017-08-28powerpc/configs: Add CONFIG_RAS now required for CONFIG_EDACMichael Ellerman
In commit e3c4ff6d8c94 ("EDAC: Remove EDAC_MM_EDAC") CONFIG_EDAC grew a dependency on CONFIG_RAS. Some of our defconfigs don't have the latter, which means we lose CONFIG_EDAC, so add CONFIG_RAS to fix that. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

In commit bf4981a00636 ("powerpc: Remove the celleb support") we dropped the celleb support, which made these symbols unselectable because we no longer select HAS_TX99_SERIAL. So drop them from the defconfigs. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
