2020-01-11Merge tag 'clone3-tls-v5.5-rc6' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull thread fixes from Christian Brauner: "This contains a series of patches to fix CLONE_SETTLS when used with clone3(). The clone3() syscall passes the tls argument through struct clone_args instead of a register. This means, all architectures that do not implement copy_thread_tls() but still support CLONE_SETTLS via copy_thread() expecting the tls to be located in a register argument based on clone() are currently unfortunately broken. Their tls value will be garbage. The patch series fixes this on all architectures that currently define __ARCH_WANT_SYS_CLONE3. It also adds a compile-time check to ensure that any architecture that enables clone3() in the future is forced to also implement copy_thread_tls(). My ultimate goal is to get rid of the copy_thread()/copy_thread_tls() split and just have copy_thread_tls() at some point in the not too distant future (Maybe even renaming copy_thread_tls() back to simply copy_thread() once the old function is ripped from all arches). This is dependent now on all arches supporting clone3(). While all relevant arches do that now there are still four missing: ia64, m68k, sh and sparc. They have the system call reserved, but not implemented. Once they all implement clone3() we can get rid of ARCH_WANT_SYS_CLONE3 and HAVE_COPY_THREAD_TLS. This series also includes a minor fix for the arm64 uapi headers which caused __NR_clone3 to be missing from the exported user headers. Unfortunately the series came in a little late especially given that it touches a range of architectures. Due to the holidays not all arch maintainers responded in time probably due to their backlog. Will and Arnd have thankfully acked the arm specific changes. Given that the changes are straightforward and rather minimal combined with the fact the that clone3() with CLONE_SETTLS is broken I decided to send them post rc3 nonetheless" * tag 'clone3-tls-v5.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: um: Implement copy_thread_tls clone3: ensure copy_thread_tls is implemented xtensa: Implement copy_thread_tls riscv: Implement copy_thread_tls parisc: Implement copy_thread_tls arm: Implement copy_thread_tls arm64: Implement copy_thread_tls arm64: Move __ARCH_WANT_SYS_CLONE3 definition to uapi headers

2020-01-06arm64: Revert support for execute-only user mappingsCatalin Marinas
The ARMv8 64-bit architecture supports execute-only user permissions by clearing the PTE_USER and PTE_UXN bits, practically making it a mostly privileged mapping but from which user running at EL0 can still execute. The downside, however, is that the kernel at EL1 inadvertently reading such mapping would not trip over the PAN (privileged access never) protection. Revert the relevant bits from commit cab15ce604e5 ("arm64: Introduce execute-only page access permissions") so that PROT_EXEC implies PROT_READ (and therefore PTE_USER) until the architecture gains proper support for execute-only user mappings.

2019-12-12KVM: arm64: Ensure 'params' is initialised when looking up sys registerWill Deacon
Commit 4b927b94d5df ("KVM: arm/arm64: vgic: Introduce find_reg_by_id()") introduced 'find_reg_by_id()', which looks up a system register only if the 'id' index parameter identifies a valid system register. As part of the patch, existing callers of 'find_reg()' were ported over to the new interface, but this breaks 'index_to_sys_reg_desc()' in the case that the initial lookup in the vCPU target table fails because we will then call into 'find_reg()' for the system register table with an uninitialised 'param' as the key to the lookup. GCC 10 is bright enough to spot this (amongst a tonne of false positives, but hey!): | arch/arm64/kvm/sys_regs.c: In function ‘index_to_sys_reg_desc.part.0.isra’: | arch/arm64/kvm/sys_regs.c:983:33: warning: ‘params.Op2’ may be used uninitialized in this function [-Wmaybe-uninitialized] | 983 | (u32)(x)->CRn, (u32)(x)->CRm, (u32)(x)->Op2); | [...] Revert the hunk of 4b927b94d5df which breaks 'index_to_sys_reg_desc()' so that the old behaviour of checking the index upfront is restored.

A64-OLinuXino-eMMC uses 1.8V for eMMC supply. This is done via a triple jumper, which sets VCC-PL to either 1.8V or 3.3V. This setting is different for boards with and without eMMC. This is not a big issue for DDR52 mode, however the eMMC will not work in HS200/HS400, since these modes explicitly requires 1.8V.

2019-12-06arm64: ftrace: fix ifdefferyMark Rutland
When I tweaked the ftrace entry assembly in commit: 3b23e4991fb66f6d ("arm64: implement ftrace with regs") ... my ifdeffery tweaks left ftrace_graph_caller undefined for CONFIG_DYNAMIC_FTRACE && CONFIG_FUNCTION_GRAPH_TRACER when ftrace is based on mcount. The kbuild test robot reported that this issue is detected at link time: | arch/arm64/kernel/entry-ftrace.o: In function `skip_ftrace_call': | arch/arm64/kernel/entry-ftrace.S:238: undefined reference to `ftrace_graph_caller' | arch/arm64/kernel/entry-ftrace.S:238:(.text+0x3c): relocation truncated to fit: R_AARCH64_CONDBR19 against undefined symbol | `ftrace_graph_caller' | arch/arm64/kernel/entry-ftrace.S:243: undefined reference to `ftrace_graph_caller' | arch/arm64/kernel/entry-ftrace.S:243:(.text+0x54): relocation truncated to fit: R_AARCH64_CONDBR19 against undefined symbol | `ftrace_graph_caller' This patch fixes the ifdeffery so that the mcount version of ftrace_graph_caller doesn't depend on CONFIG_DYNAMIC_FTRACE. At the same time, a redundant #else is removed from the ifdeffery for the patchable-function-entry version of ftrace_graph_caller.

2019-12-06arm64: KVM: Invoke compute_layout() before alternatives are appliedSebastian Andrzej Siewior
compute_layout() is invoked as part of an alternative fixup under stop_machine(). This function invokes get_random_long() which acquires a sleeping lock on -RT which can not be acquired in this context. Rename compute_layout() to kvm_compute_layout() and invoke it before stop_machine() applies the alternatives. Add a __init prefix to kvm_compute_layout() because the caller has it, too (and so the code can be discarded after boot).

2019-12-06arm64: Validate tagged addresses in access_ok() called from kernel threadsCatalin Marinas
__range_ok(), invoked from access_ok(), clears the tag of the user address only if CONFIG_ARM64_TAGGED_ADDR_ABI is enabled and the thread opted in to the relaxed ABI. The latter sets the TIF_TAGGED_ADDR thread flag. In the case of asynchronous I/O (e.g. io_submit()), the access_ok() may be called from a kernel thread. Since kernel threads don't have TIF_TAGGED_ADDR set, access_ok() will fail for valid tagged user addresses. Example from the ffs_user_copy_worker() thread: use_mm(io_data->mm); ret = ffs_copy_to_iter(io_data->buf, ret, &io_data->data); unuse_mm(io_data->mm); Relax the __range_ok() check to always untag the user address if called in the context of a kernel thread. The user pointers would have already been checked via aio_setup_rw() -> import_{single_range,iovec}() at the time of the asynchronous I/O request.

Currently kvm_pr_unimpl() is ratelimited, so print_sys_reg_instr() won't spam the console. However, someof its callers try to print some contextual information with kvm_err(), which is not ratelimited. This means that in some cases the context may be printed without the sysreg encoding, which isn't all that useful. Let's ensure that both are consistently printed together and ratelimited, by refactoring print_sys_reg_instr() so that some callers can provide it with an arbitrary format string.

Building with KASAN results in the compiler generating anonymous functions to register/unregister global variables against the shadow memory. These functions are placed in .text.startup/.text.exit, and given mangled names like _GLOBAL__sub_{I,D}_65535_0_$OTHER_SYMBOL. The kernel linker script places these in .init.text and .exit.text respectively, which are both discarded at runtime as part of initmem. Building with FTRACE_WITH_REGS uses -fpatchable-function-entry=2, which also instruments KASAN's anonymous functions. When these are discarded with the rest of initmem, ftrace removes dangling references to these call sites. Building without MODULES implicitly disables STRICT_MODULE_RWX, and causes arm64's patch_map() function to treat any !core_kernel_text() symbol as something that can be modified in-place. As core_kernel_text() is only true for .text and .init.text, with the latter depending on system_state < SYSTEM_RUNNING, we'll treat .exit.text as something that can be patched in-place. However, .exit.text is mapped read-only. Hence in this configuration the ftrace init code blows up while trying to patch one of the functions generated by KASAN. We could try to filter out the call sites in .exit.text rather than initializing them, but this would be inconsistent with how we handle .init.text, and requires hooking into core bits of ftrace. The behaviour of patch_map() is also inconsistent today, so instead let's clean that up and have it consistently handle .exit.text. This patch teaches patch_map() to handle .exit.text at init time, preventing the boot-time splat above. The flow of patch_map() is reworked to make the logic clearer and minimize redundant conditionality.

Total pages: -188245 | Kernel command line: earlycon | firmware_class.path=/vendor/firmware/ androidboot.hardware=db845c | init=/init androidboot.boot_devices=soc/1d84000.ufshc | printk.devkmsg=on buildvariant=userdebug root=/dev/sda2 | androidboot.bootdevice=1d84000.ufshc androidboot.serialno=c4e1189c | androidboot.baseband=sda | msm_drm.dsi_display0=dsi_lt9611_1080_video_display: | androidboot.slot_suffix=_a skip_initramfs rootwait ro init=/init | | <hangs indefinitely here> This is because, when CONFIG_NUMA=n, zone_sizes_init() fails to handle memblocks that fall entirely within the ZONE_DMA region and erroneously ends up trying to add a negatively-sized region into the following ZONE_DMA32, which is later interpreted as a large unsigned region by the core MM code. Rework the non-NUMA implementation of zone_sizes_init() so that the start address of the memblock being processed is adjusted according to the end of the previous zone, which is then range-checked before updating the hole information of subsequent zones.
