| 1e474b2 | Paul E. McKenney | 05 February 2020, 14:34:09 UTC | smp/up: Make smp_call_function_single() match SMP semantics In CONFIG_SMP=y kernels, smp_call_function_single() returns -ENXIO when invoked for a non-existent CPU. In contrast, in CONFIG_SMP=n kernels, a splat is emitted and smp_call_function_single() otherwise silently ignores its "cpu" argument, instead pretending that the caller intended to have something happen on CPU 0. Given that there is now code that expects smp_call_function_single() to return an error if a bad CPU was specified, this difference in semantics needs to be addressed. Bring the semantics of the CONFIG_SMP=n version of smp_call_function_single() into alignment with its CONFIG_SMP=y counterpart. Signed-off-by: Paul E.

The reason is that the automatically assigned affinity correlates to the multi-queue CPU handling of block devices. If the generated affinity mask spaws both housekeeping and isolated CPUs the interrupt could be routed to an isolated CPU which would then be disturbed by I/O submitted by a housekeeping CPU. The new mechamism ensures that as long as one housekeeping CPU is online in the assigned affinity mask the interrupt is routed to a housekeeping CPU. If there is no online housekeeping CPU in the affinity mask, then the interrupt is routed to an isolated CPU to keep the device queue intact, but unless the isolated CPU submits I/O by itself these interrupts are not raised. - A small addon to the device tree irqdomain core code to avoid duplication in irq chip drivers - Conversion of the SiFive PLIC to hierarchical domains - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP INTMUX, Meson A1 GPIO - The first cut of support for the new ARM GICv4.1 - The usual pile of fixes and improvements in core and driver code" * tag 'irq-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) genirq, sched/isolation: Isolate from handling managed interrupts irqchip/gic-v4.1: Allow direct invalidation of VLPIs irqchip/gic-v4.1: Suppress per-VLPI doorbell irqchip/gic-v4.1: Add VPE INVALL callback irqchip/gic-v4.1: Add VPE eviction callback irqchip/gic-v4.1: Add VPE residency callback irqchip/gic-v4.1: Add mask/unmask doorbell callbacks irqchip/gic-v4.1: Plumb skeletal VPE irqchip irqchip/gic-v4.1: Implement the v4.1 flavour of VMOVP irqchip/gic-v4.1: Don't use the VPE proxy if RVPEID is set irqchip/gic-v4.1: Implement the v4.1 flavour of VMAPP irqchip/gic-v4.1: VPE table (aka GICR_VPROPBASER) allocation irqchip/gic-v3: Add GICv4.1 VPEID size discovery irqchip/gic-v3: Detect GICv4.1 supporting RVPEID irqchip/gic-v3-its: Fix get_vlpi_map() breakage with doorbells irqdomain: Fix a memory leak in irq_domain_push_irq() irqchip: Add NXP INTMUX interrupt multiplexer support dt-bindings: interrupt-controller: Add binding for NXP INTMUX interrupt multiplexer irqchip: Define EXYNOS_IRQ_COMBINER irqchip/meson-gpio: Add support for meson a1 SoCs ... | 28 January 2020, 01:22:21 UTC |

Due to different boot time and non-suspended runtime these clocks can differ significantly on two hosts, in the worst case time goes backwards which is a violation of the POSIX requirements. The time namespace addresses this problem. It allows to set offsets for clock MONOTONIC and BOOTTIME once after creation and before tasks are associated with the namespace. These offsets are taken into account by timers and timekeeping including the VDSO. Offsets for wall clock based clocks (REALTIME/TAI) are not provided by this mechanism. While in theory possible, the overhead and code complexity would be immense and not justified by the esoteric potential use cases which were discussed at Plumbers '18. The overhead for tasks in the root namespace (ie where host time offsets = 0) is in the noise and great effort was made to ensure that especially in the VDSO. If time namespace is disabled in the kernel configuration the code is compiled out.

We're some time away from actually attempting to remove this in the kernel, but the only distro we know that still uses it (Fedora) is working on moving away from this so we want to at least let people know we are planning to remove it. - Reorder the SELinux hooks to help prevent bad things when SELinux is disabled at runtime. The proper fix is to remove the CONFIG_SECURITY_SELINUX_DISABLE functionality (see above) and just take care of it at boot time (e.g. "selinux=0"). - Add SELinux controls for the kernel lockdown functionality, introducing a new SELinux class/permissions: "lockdown { integrity confidentiality }". - Add a SELinux control for move_mount(2) that reuses the "file { mounton }" permission. - Improvements to the SELinux security label data store lookup functions to speed up translations between our internal label representations and the visible string labels (both directions). - Revisit a previous fix related to SELinux inode auditing and permission caching and do it correctly this time. - Fix the SELinux access decision cache to cleanup properly on error. In some extreme cases this could limit the cache size and result in a decrease in performance. - Enable SELinux per-file labeling for binderfs. - The SELinux initialized and disabled flags were wrapped with accessors to ensure they are accessed correctly. - Mark several key SELinux structures with __randomize_layout. - Changes to the LSM build configuration to only build security/lsm_audit.c when needed. - Changes to the SELinux build configuration to only build the IB object cache when CONFIG_SECURITY_INFINIBAND is enabled. - Move a number of single-caller functions into their callers. - Documentation fixes (/selinux -> /sys/fs/selinux). - A handful of cleanup patches that aren't worth mentioning on their own, the individual descriptions have plenty of detail" * tag 'selinux-pr-20200127' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: (28 commits) selinux: fix regression introduced by move_mount(2) syscall selinux: do not allocate ancillary buffer on first load selinux: remove redundant allocation and helper functions selinux: remove redundant selinux_nlmsg_perm selinux: fix wrong buffer types in policydb.c selinux: reorder hooks to make runtime disable less broken selinux: treat atomic flags more carefully selinux: make default_noexec read-only after init selinux: move ibpkeys code under CONFIG_SECURITY_INFINIBAND. selinux: remove redundant msg_msg_alloc_security Documentation,selinux: fix references to old selinuxfs mount point selinux: deprecate disabling SELinux and runtime selinux: allow per-file labelling for binderfs selinuxfs: use scnprintf to get real length for inode selinux: remove set but not used variable 'sidtab' selinux: ensure the policy has been loaded before reading the sidtab stats selinux: ensure we cleanup the internal AVC counters on error in avc_update() selinux: randomize layout of key structures selinux: clean up selinux_enabled/disabled/enforcing_boot selinux: remove unnecessary selinux cred request ... | 27 January 2020, 23:38:15 UTC |

The only scary looking one from the diffstat is the uapi change to asm-generic/mman-common.h, but this has been acked by Arnd and is actually just adding a pair of comments in an attempt to prevent allocation of some PROT values which tend to get used for arch-specific purposes. We'll be using them for Branch Target Identification (a CFI-like hardening feature), which is currently under review on the mailing list. New architecture features: - Support for Armv8.5 E0PD, which benefits KASLR in the same way as KPTI but without the overhead. This allows KPTI to be disabled on CPUs that are not affected by Meltdown, even is KASLR is enabled. - Initial support for the Armv8.5 RNG instructions, which claim to provide access to a high bandwidth, cryptographically secure hardware random number generator. As well as exposing these to userspace, we also use them as part of the KASLR seed and to seed the crng once all CPUs have come online. - Advertise a bunch of new instructions to userspace, including support for Data Gathering Hint, Matrix Multiply and 16-bit floating point. Kexec: - Cleanups in preparation for relocating with the MMU enabled - Support for loading crash dump kernels with kexec_file_load() Perf and PMU drivers: - Cleanups and non-critical fixes for a couple of system PMU drivers FPU-less (aka broken) CPU support: - Considerable fixes to support CPUs without the FP/SIMD extensions, including their presence in heterogeneous systems. Good luck finding a 64-bit userspace that handles this. Modern assembly function annotations: - Start migrating our use of ENTRY() and ENDPROC() over to the new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended to aid debuggers Kbuild: - Cleanup detection of LSE support in the assembler by introducing 'as-instr' - Remove compressed Image files when building clean targets IP checksumming: - Implement optimised IPv4 checksumming routine when hardware offload is not in use. An IPv6 version is in the works, pending testing. Hardware errata: - Work around Cortex-A55 erratum #1530923 Shadow call stack: - Work around some issues with Clang's integrated assembler not liking our perfectly reasonable assembly code - Avoid allocating the X18 register, so that it can be used to hold the shadow call stack pointer in future ACPI: - Fix ID count checking in IORT code. This may regress broken firmware that happened to work with the old implementation, in which case we'll have to revert it and try something else - Fix DAIF corruption on return from GHES handler with pseudo-NMIs Miscellaneous: - Whitelist some CPUs that are unaffected by Spectre-v2 - Reduce frequency of ASID rollover when KPTI is compiled in but inactive - Reserve a couple of arch-specific PROT flags that are already used by Sparc and PowerPC and are planned for later use with BTI on arm64 - Preparatory cleanup of our entry assembly code in preparation for moving more of it into C later on - Refactoring and cleanup" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (73 commits) arm64: acpi: fix DAIF manipulation with pNMI arm64: kconfig: Fix alignment of E0PD help text arm64: Use v8.5-RNG entropy for KASLR seed arm64: Implement archrandom.h for ARMv8.5-RNG arm64: kbuild: remove compressed images on 'make ARCH=arm64 (dist)clean' arm64: entry: Avoid empty alternatives entries arm64: Kconfig: select HAVE_FUTEX_CMPXCHG arm64: csum: Fix pathological zero-length calls arm64: entry: cleanup sp_el0 manipulation arm64: entry: cleanup el0 svc handler naming arm64: entry: mark all entry code as notrace arm64: assembler: remove smp_dmb macro arm64: assembler: remove inherit_daif macro ACPI/IORT: Fix 'Number of IDs' handling in iort_id_map() mm: Reserve asm-generic prot flags 0x10 and 0x20 for arch use arm64: Use macros instead of hard-coded constants for MAIR_EL1 arm64: Add KRYO{3,4}XX CPU cores to spectre-v2 safe list arm64: kernel: avoid x18 in __cpu_soft_restart arm64: kvm: stop treating register x18 as caller save arm64/lib: copy_page: avoid x18 register in assembler code ... | 27 January 2020, 16:58:19 UTC |

| b720530 | Christoph Hellwig | 26 January 2020, 13:05:43 UTC | block: allow partitions on host aware zone devices Host-aware SMR drives can be used with the commands to explicitly manage zone state, but they can also be used as normal disks. In the former case it makes perfect sense to allow partitions on them, in the latter it does not, just like for host managed devices. Add a check to add_partition to allow partitions on host aware devices, but give up any zone management capabilities in that case, which also catches the previously missed case of adding a partition vs just scanning it. Because sd can rescan the attribute at runtime it needs to check if a disk has partitions, for which a new helper is added to genhd.h.

In the following execution, if an error occurs, e.g., there is no more free channel, an error code EBUSY or ENOMEM will be returned. However, 'vcc' is not deallocated, leading to memory leaks. Note that, in normal cases where fs_open() returns 0, 'vcc' will be deallocated in fs_close(). But, if fs_open() fails, there is no guarantee that fs_close() will be invoked.

| 3546d8f | Michael Ellerman | 24 January 2020, 09:41:44 UTC | net: cxgb3_main: Add CAP_NET_ADMIN check to CHELSIO_GET_MEM The cxgb3 driver for "Chelsio T3-based gigabit and 10Gb Ethernet adapters" implements a custom ioctl as SIOCCHIOCTL/SIOCDEVPRIVATE in cxgb_extension_ioctl(). One of the subcommands of the ioctl is CHELSIO_GET_MEM, which appears to read memory directly out of the adapter and return it to userspace. It's not entirely clear what the contents of the adapter memory contains, but the assumption is that it shouldn't be accessible to all users. So add a CAP_NET_ADMIN check to the CHELSIO_GET_MEM case. Put it after the is_offload() check, which matches two of the other subcommands in the same function which also check for is_offload() and CAP_NET_ADMIN.

Drop that while touching this area.

| c79108b | Stephen Boyd | 24 January 2020, 05:58:46 UTC | alarmtimer: Make alarmtimer platform device child of RTC device The alarmtimer_suspend() function will fail if an RTC device is on a bus such as SPI or i2c and that RTC device registers and probes after alarmtimer_init() registers and probes the 'alarmtimer' platform device. This is because system wide suspend suspends devices in the reverse order of their probe. When alarmtimer_suspend() attempts to program the RTC for a wakeup it will try to program an RTC device on a bus that has already been suspended. Move the alarmtimer device registration to happen when the RTC which is used for wakeup is registered. Register the 'alarmtimer' platform device as a child of the RTC device too, so that it can be guaranteed that the RTC device won't be suspended when alarmtimer_suspend() is called.

Fix: There is no need to update skb->csum in inet_proto_csum_replace16(), because update in two fields a.) IPv6 src/dst address and b.) L4 header checksum cancels each other for skb->csum calculation. Whereas inet_proto_csum_replace4 function needs to update skb->csum, because update in 3 fields a.) IPv4 src/dst address, b.) IPv4 Header checksum and c.) L4 header checksum results in same diff as L4 Header checksum for skb->csum calculation.

| eb014de | Pablo Neira Ayuso | 21 January 2020, 15:48:03 UTC | netfilter: nf_tables: autoload modules from the abort path This patch introduces a list of pending module requests. This new module list is composed of nft_module_request objects that contain the module name and one status field that tells if the module has been already loaded (the 'done' field). In the first pass, from the preparation phase, the netlink command finds that a module is missing on this list. Then, a module request is allocated and added to this list and nft_request_module() returns -EAGAIN. This triggers the abort path with the autoload parameter set on from nfnetlink, request_module() is called and the module request enters the 'done' state. Since the mutex is released when loading modules from the abort phase, the module list is zapped so this is iteration occurs over a local list. Therefore, the request_module() calls happen when object lists are in consistent state (after fulling aborting the transaction) and the commit list is empty. On the second pass, the netlink command will find that it already tried to load the module, so it does not request it again and nft_request_module() returns 0. Then, there is a look up to find the object that the command was missing. If the module was successfully loaded, the command proceeds normally since it finds the missing object in place, otherwise -ENOENT is reported to userspace. This patch also updates nfnetlink to include the reason to enter the abort phase, which is required for this new autoload module rationale.
