Pull clone3 fix from Christian Brauner: "This is a last-minute bugfix for clone3() that should go in before we release 5.3 with clone3(). clone3() did not verify that the exit_signal argument was set to a valid signal. This can be used to cause a crash by specifying a signal greater than NSIG. e.g. -1. The commit from Eugene adds a check to copy_clone_args_from_user() to verify that the exit signal is limited by CSIGNAL as with legacy clone() and that the signal is valid. With this we don't get the legacy clone behavior were an invalid signal could be handed down and would only be detected and then ignored in do_notify_parent(). Users of clone3() will now get a proper error right when they pass an invalid exit signal. Note, that this is not a change in user-visible behavior since no kernel with clone3() has been released yet" * tag 'for-linus-20190912' of gitolite.kernel.org:pub/scm/linux/kernel/git/brauner/linux: fork: block invalid exit signals with clone3()

Previously, higher 32 bits of exit_signal fields were lost when copied to the kernel args structure (that uses int as a type for the respective field). Moreover, as Oleg has noted, exit_signal is used unchecked, so it has to be checked for sanity before use; for the legacy syscalls, applying CSIGNAL mask guarantees that it is at least non-negative; however, there's no such thing is done in clone3() code path, and that can break at least thread_group_leader. This commit adds a check to copy_clone_args_from_user() to verify that the exit signal is limited by CSIGNAL as with legacy clone() and that the signal is valid. With this we don't get the legacy clone behavior were an invalid signal could be handed down and would only be detected and ignored in do_notify_parent(). Users of clone3() will now get a proper error when they pass an invalid exit signal. Note, that this is not user-visible behavior since no kernel with clone3() has been released yet. The following program will cause a splat on a non-fixed clone3() version and will fail correctly on a fixed version: #define _GNU_SOURCE #include <linux/sched.h> #include <linux/types.h> #include <sched.h> #include <stdio.h> #include <stdlib.h> #include <sys/syscall.h> #include <sys/wait.h> #include <unistd.h> int main(int argc, char *argv[]) { pid_t pid = -1; struct clone_args args = {0}; args.exit_signal = -1; pid = syscall(__NR_clone3, &args, sizeof(struct clone_args)); if (pid < 0) exit(EXIT_FAILURE); if (pid == 0) exit(EXIT_SUCCESS); wait(NULL); exit(EXIT_SUCCESS); } Fixes: 7f192e3c ("fork: add clone3") Reported-by:

Commit 674fa8da ("pinctrl: aspeed-g5: Delay acquisition of regmaps") was determined to be a partial fix to the problem of acquiring the LPC Host Controller and GFX regmaps: The AST2500 pin controller may need to fetch syscon regmaps during expression evaluation as well as when setting mux state. For example, this case is hit by attempting to export pins exposing the LPC Host Controller as GPIOs. An optional eval() hook is added to the Aspeed pinmux operation struct and called from aspeed_sig_expr_eval() if the pointer is set by the SoC-specific driver. This enables the AST2500 to perform the custom action of acquiring its regmap dependencies as required. John Wang tested the fix on an Inspur FP5280G2 machine (AST2500-based) where the issue was found, and I've booted the fix on Witherspoon (AST2500) and Palmetto (AST2400) machines, and poked at relevant pins under QEMU by forcing mux configurations via devmem before exporting GPIOs to exercise the driver.

The code assumes log_num < in_num everywhere, and that is true as long as in_num is incremented by descriptor iov count, and log_num by 1. However this breaks if there's a zero sized descriptor. As a result, if a malicious guest creates a vring desc with desc.len = 0, it may cause the host kernel to crash by overflowing the log array. This bug can be triggered during the VM migration. There's no need to log when desc.len = 0, so just don't increment log_num in this case. Fixes: 3a4d5c94 ("vhost_net: a kernel-level virtio server") Cc: stable@vger.kernel.org Reviewed-by:

iovec addresses coming from vhost are assumed to be pre-validated, but in fact can be speculated to a value out of range. Userspace address are later validated with array_index_nospec so we can be sure kernel info does not leak through these addresses, but vhost must also not leak userspace info outside the allowed memory table to guests. Following the defence in depth principle, make sure the address is not validated out of node range. Signed-off-by:

Another day; another DSDT bug we need to workaround... Since commit ca876c74 ("gpiolib-acpi: make sure we trigger edge events at least once on boot") we call _AEI edge handlers at boot. In some rare cases this causes problems. One example of this is the Minix Neo Z83-4 mini PC, this device has a clear DSDT bug where it has some copy and pasted code for dealing with Micro USB-B connector host/device role switching, while the mini PC does not even have a micro-USB connector. This code, which should not be there, messes with the DDC data pin from the HDMI connector (switching it to GPIO mode) breaking HDMI support. To avoid problems like this, this commit adds a new gpiolib_acpi.run_edge_events_on_boot kernel commandline option, which allows disabling the running of _AEI edge event handlers at boot. The default value is -1/auto which uses a DMI based blacklist, the initial version of this blacklist contains the Neo Z83-4 fixing the HDMI breakage.

We should only try to execute fallback quirks handling when previous call returned -ENOENT, and not when we did not get -EPROBE_DEFER. The other errors should be treated as hard errors: we did find the GPIO description, but for some reason we failed to handle it properly. The fallbacks should only be executed when previous handlers returned -ENOENT, which means the mapping/description was not found. Also let's remove the explicit deferral handling when iterating through GPIO suffixes: it is not needed anymore as we will not be calling fallbacks for anything but -ENOENT.

The function virtqueue_add_split() DMA-maps the scatterlist buffers. In case a mapping error occurs the already mapped buffers must be unmapped. This happens by jumping to the 'unmap_release' label. In case of indirect descriptors the release is wrong and may leak kernel memory. Because the implementation assumes that the head descriptor is already mapped it starts iterating over the descriptor list starting from the head descriptor. However for indirect descriptors the head descriptor is never mapped in case of an error. The fix is to initialize the start index with zero in case of indirect descriptors and use the 'desc' pointer directly for iterating over the descriptor chain. Signed-off-by:

KVM guests with commit c8c40767 ("x86/timer: Skip PIT initialization on modern chipsets") applied to guest kernel have been observed to have unusually higher CPU usage with symptoms of increase in vm exits for HLT and MSW_WRITE (MSR_IA32_TSCDEADLINE). This is caused by older QEMUs lacking support for X86_FEATURE_ARAT. lapic clock retains CLOCK_EVT_FEAT_C3STOP and nohz stays inactive. There's no usable broadcast device either. Do the PIT initialization if guest CPU lacks X86_FEATURE_ARAT. On real hardware it shouldn't matter as ARAT and DEADLINE come together.

This reverts commit 558682b5. Chris Wilson reports that it breaks his CPU hotplug test scripts. In particular, it breaks offlining and then re-onlining the boot CPU, which we treat specially (and the BIOS does too). The symptoms are that we can offline the CPU, but it then does not come back online again: smpboot: CPU 0 is now offline smpboot: Booting Node 0 Processor 0 APIC 0x0 smpboot: do_boot_cpu failed(-1) to wakeup CPU#0 Thomas says he knows why it's broken (my personal suspicion: our magic handling of the "cpu0_logical_apicid" thing), but for 5.3 the right fix is to just revert it, since we've never touched the LDR bits before, and it's not worth the risk to do anything else at this stage. [ Hotpluging of the boot CPU is special anyway, and should be off by default. See the "BOOTPARAM_HOTPLUG_CPU0" config option and the cpu0_hotplug kernel parameter. In general you should not do it, and it has various known limitations (hibernate and suspend require the boot CPU, for example). But it should work, even if the boot CPU is special and needs careful treatment - Linus ] Link: https://lore.kernel.org/lkml/156785100521.13300.14461504732265570003@skylake-alporthouse-com/Reported-by:

Matt bisected a sparc64 specific issue with semctl, shmctl and msgctl to a commit from my y2038 series in linux-5.1, as I missed the custom sys_ipc() wrapper that sparc64 uses in place of the generic version that I patched. The problem is that the sys_{sem,shm,msg}ctl() functions in the kernel now do not allow being called with the IPC_64 flag any more, resulting in a -EINVAL error when they don't recognize the command. Instead, the correct way to do this now is to call the internal ksys_old_{sem,shm,msg}ctl() functions to select the API version. As we generally move towards these functions anyway, change all of sparc_ipc() to consistently use those in place of the sys_*() versions, and move the required ksys_*() declarations into linux/syscalls.h The IS_ENABLED(CONFIG_SYSVIPC) check is required to avoid link errors when ipc is disabled.

As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1 broke when commit 00bf25d6 ("y2038: use time32 syscall names on 32-bit") changed all system calls on all architectures that take a 32-bit time_t to point to the _time32 implementation, but left out semtimedop in the asm-generic header. This affects all 32-bit architectures using asm-generic/unistd.h: h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky. The notable exception is riscv32, which has dropped support for the time32 system calls entirely. Reported-by:

Pull IOMMU fixes from Joerg Roedel: - Revert an Intel VT-d patch that caused problems for some users. - Removal of a feature in the Intel VT-d driver that was never supported in hardware. This qualifies as a fix because the code for this feature sets reserved bits in the invalidation queue descriptor, causing failed invalidations on real hardware. - Two fixes for AMD IOMMU driver to fix a race condition and to add a missing IOTLB flush when kernel is booted in kdump mode. * tag 'iommu-fixes-v5.3-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Fix race in increase_address_space() iommu/amd: Flush old domains in kdump kernel iommu/vt-d: Remove global page flush support Revert "iommu/vt-d: Avoid duplicated pci dma alias consideration"
