* arm64: mm: avoid calling apply_to_page_range on empty rangeMika Penttilä2016-01-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Calling apply_to_page_range with an empty range results in a BUG_ON from the core code. This can be triggered by trying to load the st_drv module with CONFIG_DEBUG_SET_MODULE_RONX enabled: kernel BUG at mm/memory.c:1874! Internal error: Oops - BUG: 0 [#1] PREEMPT SMP Modules linked in: CPU: 3 PID: 1764 Comm: insmod Not tainted 4.5.0-rc1+ #2 Hardware name: ARM Juno development board (r0) (DT) task: ffffffc9763b8000 ti: ffffffc975af8000 task.ti: ffffffc975af8000 PC is at apply_to_page_range+0x2cc/0x2d0 LR is at change_memory_common+0x80/0x108 This patch fixes the issue by making change_memory_common (called by the set_memory_* functions) a NOP when numpages == 0, therefore avoiding the erroneous call to apply_to_page_range and bringing us into line with x86 and s390.

* arm64: errata: Add -mpc-relative-literal-loads to build flagsdann frazier2016-01-261-0/+1
| | | | | | | | | | | | | | | | | | | GCC6 (and Linaro's 2015.12 snapshot of GCC5) has a new default that uses adrp/ldr or adrp/add to address literal pools. When CONFIG_ARM64_ERRATUM_843419 is enabled, modules built with this toolchain fail to load: module libahci: unsupported RELA relocation: 275 This patch fixes the problem by passing '-mpc-relative-literal-loads' to the compiler.

* Eliminate the .eh_frame sections from the aarch64 vmlinux and kernel modulesWilliam Cohen2016-01-261-0/+1
| | | | | | | | | | | | By default the aarch64 gcc generates .eh_frame sections. Unlike .debug_frame sections, the .eh_frame sections are loaded into memory when the associated code is loaded. On an example kernel being built with this default the .eh_frame section in vmlinux used an extra 1.7MB of memory. The x86 disables the creation of the .eh_frame section. The aarch64 should probably do the same to save some memory. Signed-off-by: William Cohen <wcohen@redhat.com> Signed-off-by: Will Deacon <will.deacon@arm.com>

* arm64: Honour !PTE_WRITE in set_pte_at() for kernel mappingsCatalin Marinas2016-01-251-11/+10
| | | | | | | | | | | | | | | | | | | | | | Currently, set_pte_at() only checks the software PTE_WRITE bit for user mappings when it sets or clears the hardware PTE_RDONLY accordingly. The kernel ptes are written directly without any modification, relying solely on the protection bits in macros like PAGE_KERNEL. However, modifying kernel pte attributes via pte_wrprotect() would be ignored by set_pte_at(). Since pte_wrprotect() does not set PTE_RDONLY (it only clears PTE_WRITE), the new permission is not taken into account. This patch changes set_pte_at() to adjust the read-only permission for kernel ptes as well. As a side effect, existing PROT_* definitions used for kernel ioremap*() need to include PTE_DIRTY | PTE_WRITE. (additionally, white space fix for PTE_KERNEL_ROX) Acked-by: Andrey Ryabinin <aryabinin@virtuozzo.com> Tested-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Reported-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
* arm64: kernel: fix architected PMU registers unconditional accessLorenzo Pieralisi2016-01-253-2/+19
| | | | | | | | | | | | | | | | | | | | | | The Performance Monitors extension is an optional feature of the AArch64 architecture, therefore, in order to access Performance Monitors registers safely, the kernel should detect the architected PMU unit presence through the ID_AA64DFR0_EL1 register PMUVer field before accessing them. This patch implements a guard by reading the ID_AA64DFR0_EL1 register PMUVer field to detect the architected PMU presence and prevent accessing PMU system registers if the Performance Monitors extension is not implemented in the core.

* arm64: kasan: ensure that the KASAN zero page is mapped read-onlyArd Biesheuvel2016-01-251-0/+9
| | | | | | | | | | | | | | | | | When switching from the early KASAN shadow region, which maps the entire shadow space read-write, to the permanent KASAN shadow region, which uses a zero page to shadow regions that are not subject to instrumentation, the lowest level table kasan_zero_pte[] may be reused unmodified, which means that the mappings of the zero page that it contains will still be read-write. So update it explicitly to map the zero page read only when we activate the permanent mapping.

* arm64: hide __efistub_ aliases from kallsymsArd Biesheuvel2016-01-251-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e8f3010f7326 ("arm64/efi: isolate EFI stub from the kernel proper") isolated the EFI stub code from the kernel proper by prefixing all of its symbols with __efistub_, and selectively allowing access to core kernel symbols from the stub by emitting __efistub_ aliases for functions and variables that the stub can access legally. As an unintended side effect, these aliases are emitted into the kallsyms symbol table, which means they may turn up in backtraces, e.g., ... PC is at __efistub_memset+0x108/0x200 LR is at fixup_init+0x3c/0x48 ... [<ffffff8008328608>] __efistub_memset+0x108/0x200 [<ffffff8008094dcc>] free_initmem+0x2c/0x40 [<ffffff8008645198>] kernel_init+0x20/0xe0 [<ffffff8008085cd0>] ret_from_fork+0x10/0x40 The backtrace in question has nothing to do with the EFI stub, but simply returns one of the several aliases of memset() that have been recorded in the kallsyms table. This is undesirable, since it may suggest to people who are not aware of this that the issue they are seeing is somehow EFI related. So hide the __efistub_ aliases from kallsyms, by emitting them as absolute linker symbols explicitly. The distinction between those and section relative symbols is completely irrelevant to these definitions, and to the final link we are performing when these definitions are being taken into account (the distinction is only relevant to symbols defined inside a section definition when performing a partial link), and so the resulting values are identical to the original ones. Since absolute symbols are ignored by kallsyms, this will result in these values to be omitted from its symbol table. After this patch, the backtrace generated from the same address looks like this: ... PC is at __memset+0x108/0x200 LR is at fixup_init+0x3c/0x48 ... [<ffffff8008328608>] __memset+0x108/0x200 [<ffffff8008094dcc>] free_initmem+0x2c/0x40 [<ffffff8008645198>] kernel_init+0x20/0xe0 [<ffffff8008085cd0>] ret_from_fork+0x10/0x40 Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Will Deacon <will.deacon@arm.com>

There are tools that can generate charts of the boot time, but it's sometimes convenient to see this live and without the need to go through scripts to parse the logs first. Also, this option is enabled on a large number of configurations, not enabling it is confusing because the boot log looks very different from what one is used to.
