Recommend Workaround: To determine what instruction the guest was executing the hypervisor will have to decode the instruction at the instruction pointer. The recommended workaround can not be implemented for the SEV guest because guest memory is encrypted with the guest specific key, and instruction decoder will not be able to decode the instruction bytes. If we hit this errata in the SEV guest then log the message and request a guest shutdown.

The lapic_shutdown() function which is called in sys_reboot path will not disarm the flying timer, it just masks LVTT. lapic_shutdown() clears APIC state w/ LVT_MASKED and timer-mode bit is 0, this can trigger timer-mode switch between tsc-deadline and oneshot/periodic, which can result in preemption timer be cancelled in apic_update_lvtt(). However, We can't depend on this when not exposing tsc-deadline mode and oneshot/periodic modes emulated by preemption timer.

This is due to wrong BAT allocation for the KASAN area: ---[ Data Block Address Translation ]--- 0: 0xc0000000-0xcfffffff 0x00000000 256M Kernel rw m 1: 0xd0000000-0xdfffffff 0x10000000 256M Kernel rw m 2: 0xe0000000-0xefffffff 0x20000000 256M Kernel rw m 3: 0xf8000000-0xf9ffffff 0x2a000000 32M Kernel rw m 4: 0xfa000000-0xfdffffff 0x2c000000 64M Kernel rw m A BAT must have both virtual and physical addresses alignment matching the size of the BAT. This is not the case for BAT 4 above. Fix kasan_init_region() by using block_size() function that is in book3s32/mmu.c. To be able to reuse it here, make it non static and change its name to bat_block_size() in order to avoid name conflict with block_size() defined in <linux/blkdev.h> Also reuse find_free_bat() to avoid an error message from setbat() when no BAT is available. And allocate memory outside of linear memory mapping to avoid wasting that precious space. With this change we get correct alignment for BATs and KASAN shadow memory is allocated outside the linear memory space. ---[ Data Block Address Translation ]--- 0: 0xc0000000-0xcfffffff 0x00000000 256M Kernel rw 1: 0xd0000000-0xdfffffff 0x10000000 256M Kernel rw 2: 0xe0000000-0xefffffff 0x20000000 256M Kernel rw 3: 0xf8000000-0xfbffffff 0x7c000000 64M Kernel rw 4: 0xfc000000-0xfdffffff 0x7a000000 32M Kernel rw Fixes: 7974c4732642 ("powerpc/32s: Implement dedicated kasan_init_region()") Cc: stable(a)vger.kernel.org Reported-by: Maxime Bizon <mbizon(a)freebox.fr> Signed-off-by: Christophe Leroy <christophe.leroy(a)csgroup.eu> Tested-by: Maxime Bizon <mbizon(a)freebox.fr> Signed-off-by: Michael Ellerman <mpe(a)ellerman.id.au> Link: https://lore.kernel.org/r/7a50ef902494d1325227d47d33dada01e52e5518.16418187… diff --git a/arch/powerpc/include/asm/book3s/32/mmu-hash.h b/arch/powerpc/include/asm/book3s/32/mmu-hash.h index 7be27862329f..78c6a5fde1d6 100644 --- a/arch/powerpc/include/asm/book3s/32/mmu-hash.h +++ b/arch/powerpc/include/asm/book3s/32/mmu-hash.h @@ -223,6 +223,8 @@ static __always_inline void update_user_segments(u32 val) update_user_segment(15, val); } +int __init find_free_bat(void); +unsigned int bat_block_size(unsigned long base, unsigned long top); #endif /* !__ASSEMBLY__ */ /* We happily ignore the smaller BATs on 601, we don't actually use diff --git a/arch/powerpc/mm/book3s32/mmu.c b/arch/powerpc/mm/book3s32/mmu.c index 94045b265b6b..203735caf691 100644 --- a/arch/powerpc/mm/book3s32/mmu.c +++ b/arch/powerpc/mm/book3s32/mmu.c @@ -76,7 +76,7 @@ unsigned long p_block_mapped(phys_addr_t pa) return 0; } -static int __init find_free_bat(void) +int __init find_free_bat(void) { int b; int n = mmu_has_feature(MMU_FTR_USE_HIGH_BATS) ? 8 : 4; @@ -100,7 +100,7 @@ static int __init find_free_bat(void) * - block size has to be a power of two.

FAILED: patch "[PATCH] tracing: Propagate is_signed to expression" failed to apply to 5.4-stable tree
