2019-06-26arm64: kaslr: keep modules inside module region when KASAN is enabledArd Biesheuvel1-2/+6
When KASLR and KASAN are both enabled, we keep the modules where they are, and randomize the placement of the kernel so it is within 2 GB of the module region. The reason for this is that putting modules in the vmalloc region (like we normally do when KASLR is enabled) is not possible in this case, given that the entire vmalloc region is already backed by KASAN zero shadow pages, and so allocating dedicated KASAN shadow space as required by loaded modules is not possible. The default module allocation window is set to [_etext - 128MB, _etext] in kaslr.c, which is appropriate for KASLR kernels booted without a seed or with 'nokaslr' on the command line. However, as it turns out, it is not quite correct for the KASAN case, since it still intersects the vmalloc region at the top, where attempts to allocate shadow pages will collide with the KASAN zero shadow pages, causing a WARN() and all kinds of other trouble. So cap the top end to MODULES_END explicitly when running with KASAN.

2019-06-26arm64/mm: Drop [PTE|PMD]_TYPE_FAULTAnshuman Khandual1-2/+0
This was added part of the original commit which added MMU definitions. commit 4f04d8f00545 ("arm64: MMU definitions"). These symbols never got used as confirmed from a git log search. git log -p arch/arm64/ | grep PTE_TYPE_FAULT git log -p arch/arm64/ | grep PMD_TYPE_FAULT These probably meant to identify non present entries which can now be achieved with PMD_SECT_VALID or PTE_VALID bits. Hence just drop these unused symbols which are not required anymore.

2019-06-25arm64: Implement panic_smp_self_stop()Aaro Koskinen1-6/+13
Currently arm64 uses the default implementation of panic_smp_self_stop() where the CPU runs in a cpu_relax() loop unable to receive IPIs anymore. As a result, when two CPUs panic() simultaneously we get "SMP: failed to stop secondary CPUs" warnings and extra delays before a reset, because smp_send_stop() still tries to stop the other paniced CPU. Provide an implementation of panic_smp_self_stop() that is identical to the IPI CPU stop handler, so that the online status of stopped CPUs gets properly updated.

2019-06-24arm64: bpf: do not allocate executable memoryArd Biesheuvel1-1/+1

In order to avoid transient inconsistencies where freed code pages are remapped writable while stale TLB entries still exist on other cores, mark the kprobes text pages with the VM_FLUSH_RESET_PERMS attribute. This instructs the core vmalloc code not to defer the TLB flush when this region is unmapped and returned to the page allocator.

Some Qualcomm Snapdragon based laptops built to run Microsoft Windows are clearly ACPI 5.1 based, given that that is the first ACPI revision that supports ARM, and introduced the FADT 'arm_boot_flags' field, which has a non-zero field on those systems. So in these cases, infer from the ARM boot flags that the FADT must be 5.1 or later, and treat it as 5.1.
