2023-07-08bootmem: remove the vmemmap pages from kmemleak in free_bootmem_pageLiu Shixin
commit dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem") fix an overlaps existing problem of kmemleak. But the problem still existed when HAVE_BOOTMEM_INFO_NODE is disabled, because in this case, free_bootmem_page() will call free_reserved_page() directly. Fix the problem by adding kmemleak_free_part() in free_bootmem_page() when HAVE_BOOTMEM_INFO_NODE is disabled.

2023-07-04net: dsa: sja1105: always enable the send_meta optionsVladimir Oltean
incl_srcpt has the limitation, mentioned in commit b4638af8885a ("net: dsa: sja1105: always enable the INCL_SRCPT option"), that frames with a MAC DA of 01:80:c2:xx:yy:zz will be received as 01:80:c2:00:00:zz unless PTP RX timestamping is enabled. The incl_srcpt option was initially unconditionally enabled, then that changed with commit 42824463d38d ("net: dsa: sja1105: Limit use of incl_srcpt to bridge+vlan mode"), then again with b4638af8885a ("net: dsa: sja1105: always enable the INCL_SRCPT option"). Bottom line is that it now needs to be always enabled, otherwise the driver does not have a reliable source of information regarding source_port and switch_id for link-local traffic (tag_8021q VLANs may be imprecise since now they identify an entire bridging domain when ports are not standalone). If we accept that PTP RX timestamping (and therefore, meta frame generation) is always enabled in hardware, then that limitation could be avoided and packets with any MAC DA can be properly received, because meta frames do contain the original bytes from the MAC DA of their associated link-local packet. This change enables meta frame generation unconditionally, which also has the nice side effects of simplifying the switch control path (a switch reset is no longer required on hwtstamping settings change) and the tagger data path (it no longer needs to be informed whether to expect meta frames or not - it always does).

2023-07-04net: Replace strlcpy with strscpyAzeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

Firstly, the 1394 OHCI specification defines method to retrieve hardware time stamps for asynchronous communication, which was previously unavailable in user space. This adds new events to the UAPI, allowing applications to retrieve the time when asynchronous packet are received and sent. The new events are tested in the bleeding edge of libhinawa and look to work well.

2023-07-03rdma: fix INFINIBAND_USER_ACCESS dependencyArnd Bergmann
After a change to the bnxt_re driver, it fails to link when CONFIG_INFINIBAND_USER_ACCESS is disabled: aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o: in function `bnxt_re_handler_BNXT_RE_METHOD_ALLOC_PAGE': ib_verbs.c:(.text+0xd64): undefined reference to `ib_uverbs_get_ucontext_file' aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x168): undefined reference to `uverbs_idr_class' aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x1a8): undefined reference to `uverbs_destroy_def_handler' The problem is that the 'bnxt_re_uapi_defs' structure is built unconditionally and references a couple of functions that are never really called in this configuration but instead require other functions that are left out. Adding an #ifdef around the new code, or a Kconfig dependency would address this problem, but adding the compile-time check inside of the UAPI_DEF_CHAIN_OBJ_TREE_NAMED() macro seems best because that also addresses the problem in other drivers that may run into the same dependency.

Pull kvm updates from Paolo Bonzini: "ARM64: - Eager page splitting optimization for dirty logging, optionally allowing for a VM to avoid the cost of hugepage splitting in the stage-2 fault path. - Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with services that live in the Secure world. pKVM intervenes on FF-A calls to guarantee the host doesn't misuse memory donated to the hyp or a pKVM guest. - Support for running the split hypervisor with VHE enabled, known as 'hVHE' mode. This is extremely useful for testing the split hypervisor on VHE-only systems, and paves the way for new use cases that depend on having two TTBRs available at EL2. - Generalized framework for configurable ID registers from userspace. KVM/arm64 currently prevents arbitrary CPU feature set configuration from userspace, but the intent is to relax this limitation and allow userspace to select a feature set consistent with the CPU. - Enable the use of Branch Target Identification (FEAT_BTI) in the hypervisor. - Use a separate set of pointer authentication keys for the hypervisor when running in protected mode, as the host is untrusted at runtime. - Ensure timer IRQs are consistently released in the init failure paths. - Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps (FEAT_EVT), as it is a register commonly read from userspace. - Erratum workaround for the upcoming AmpereOne part, which has broken hardware A/D state management.

2023-07-03execve: always mark stack as growing down during early stack setupLinus Torvalds
While our user stacks can grow either down (all common architectures) or up (parisc and the ia64 register stack), the initial stack setup when we copy the argument and environment strings to the new stack at execve() time is always done by extending the stack downwards. But it turns out that in commit 8d7071af8907 ("mm: always expand the stack with the mmap write lock held"), as part of making the stack growing code more robust, 'expand_downwards()' was now made to actually check the vma flags: if (!(vma->vm_flags & VM_GROWSDOWN)) return -EFAULT; and that meant that this execve-time stack expansion started failing on parisc, because on that architecture, the stack flags do not contain the VM_GROWSDOWN bit. At the same time the new check in expand_downwards() is clearly correct, and simplified the callers, so let's not remove it. The solution is instead to just codify the fact that yes, during execve(), the stack grows down. This not only matches reality, it ends up being particularly simple: we already have special execve-time flags for the stack (VM_STACK_INCOMPLETE_SETUP) and use those flags to avoid page migration during this setup time (see vma_is_temporary_stack() and invalid_migration_vma()). So just add VM_GROWSDOWN to that set of temporary flags, and now our stack flags automatically match reality, and the parisc stack expansion works again. Note that the VM_STACK_INCOMPLETE_SETUP bits will be cleared when the stack is finalized, so we only add the extra VM_GROWSDOWN bit on CONFIG_STACK_GROWSUP architectures (ie parisc) rather than adding it in general.

2023-07-03vhost: Allow worker switching while work is queueingMike Christie
This patch drops the requirement that we can only switch workers if work has not been queued by using RCU for the vq based queueing paths and a mutex for the device wide flush. We can also use this to support SIGKILL properly in the future where we should exit almost immediately after getting that signal. With this patch, when get_signal returns true, we can set the vq->worker to NULL and do a synchronize_rcu to prevent new work from being queued to the vhost_task that has been killed.

2023-07-03vhost: allow userspace to create workersMike Christie
For vhost-scsi with 3 vqs or more and a workload that tries to use them in parallel like: fio --filename=/dev/sdb --direct=1 --rw=randrw --bs=4k \ --ioengine=libaio --iodepth=128 --numjobs=3 the single vhost worker thread will become a bottlneck and we are stuck at around 500K IOPs no matter how many jobs, virtqueues, and CPUs are used. To better utilize virtqueues and available CPUs, this patch allows userspace to create workers and bind them to vqs. You can have N workers per dev and also share N workers with M vqs on that dev. This patch adds the interface related code and the next patch will hook vhost-scsi into it. The patches do not try to hook net and vsock into the interface because: 1. multiple workers don't seem to help vsock. The problem is that with only 2 virtqueues we never fully use the existing worker when doing bidirectional tests. This seems to match vhost-scsi where we don't see the worker as a bottleneck until 3 virtqueues are used. 2. net already has a way to use multiple workers.

Pull CXL updates from Dan Williams: "The highlights in terms of new functionality are support for the standard CXL Performance Monitor definition that appeared in CXL 3.0, support for device sanitization (wiping all data from a device), secure-erase (re-keying encryption of user data), and support for firmware update. The firmware update support is notable as it reuses the simple sysfs_upload interface to just cat(1) a blob to a sysfs file and pipe that to the device. Additionally there are a substantial number of cleanups and reorganizations to get ready for RCH error handling (RCH == Restricted CXL Host == current shipping hardware generation / pre CXL-2.0 topologies) and type-2 (accelerator / vendor specific) devices. For vendor specific devices they implement a subset of what the generic type-3 (generic memory expander) driver expects. As a result the rework decouples optional infrastructure from the core driver context. For RCH topologies, where the specification working group did not want to confuse pre-CXL-aware operating systems, many of the standard registers are hidden which makes support standard bus features like AER (PCIe Advanced Error Reporting) difficult. The rework arranges for the driver to help the PCI-AER core. Bjorn is on board with this direction but a late regression disocvery means the completion of this functionality needs to cook a bit longer, so it is code reorganizations only for now. Summary: - Add infrastructure for supporting background commands along with support for device sanitization and firmware update - Introduce a CXL performance monitoring unit driver based on the common definition in the specification. - Land some preparatory cleanup and refactoring for the anticipated arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1 topology) error handling. - Rework CPU cache management with respect to region configuration (device hotplug or other dynamic changes to memory interleaving) - Fix region reconfiguration vs CXL decoder ordering rules" * tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (51 commits) cxl: Fix one kernel-doc comment cxl/pci: Use correct flag for sanitize polling docs: perf: Minimal introduction the the CXL PMU device and driver perf: CXL Performance Monitoring Unit driver tools/testing/cxl: add firmware update emulation to CXL memdevs tools/testing/cxl: Use named effects for the Command Effect Log tools/testing/cxl: Fix command effects for inject/clear poison cxl: add a firmware update mechanism using the sysfs firmware loader cxl/test: Add Secure Erase opcode support cxl/mem: Support Secure Erase cxl/test: Add Sanitize opcode support cxl/mem: Wire up Sanitization support cxl/mbox: Add sanitization handling machinery cxl/mem: Introduce security state sysfs file cxl/mbox: Allow for IRQ_NONE case in the isr Revert "cxl/port: Enable the HDM decoder capability for switch ports" cxl/memdev: Formalize endpoint port linkage cxl/pci: Unconditionally unmask 256B Flit errors cxl/region: Manage decoder target_type at decoder-attach time cxl/hdm: Default CXL_DEVTYPE_DEVMEM decoders to CXL_DECODER_DEVMEM ...

2023-07-01mm: Update do_vmi_align_munmap() return semanticsLiam R. Howlett
Since do_vmi_align_munmap() will always honor the downgrade request on the success, the callers no longer have to deal with confusing return codes. Since all callers that request downgrade actually want the lock to be dropped, change the downgrade to an unlock request. Note that the lock still needs to be held in read mode during the page table clean up to avoid races with a map request. Update do_vmi_align_munmap() to return 0 for success. Clean up the callers and comments to always expect the unlock to be honored on the success path. The error path will always leave the lock untouched. As part of the cleanup, the wrapper function do_vmi_munmap() and callers to the wrapper are also updated.

2023-07-01Merge patch series "riscv: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION"Palmer Dabbelt
Jisheng Zhang <jszhang@kernel.org> says: When trying to run linux with various opensource riscv core on resource limited FPGA platforms, for example, those FPGAs with less than 16MB SDRAM, I want to save mem as much as possible. One of the major technologies is kernel size optimizations, I found that riscv does not currently support HAVE_LD_DEAD_CODE_DATA_ELIMINATION, which passes -fdata-sections, -ffunction-sections to CFLAGS and passes the --gc-sections flag to the linker. This not only benefits my case on FPGA but also benefits defconfigs. Here are some notable improvements from enabling this with defconfigs: nommu_k210_defconfig: text data bss dec hex 1112009 410288 59837 1582134 182436 before 962838 376656 51285 1390779 1538bb after rv32_defconfig: text data bss dec hex 8804455 2816544 290577 11911576 b5c198 before 8692295 2779872 288977 11761144 b375f8 after defconfig: text data bss dec hex 9438267 3391332 485333 13314932 cb2b74 before 9285914 3350052 483349 13119315 c82f53 after patch1 and patch2 are clean ups. patch3 fixes a typo. patch4 finally enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for riscv. * b4-shazam-merge: riscv: disable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for LLD riscv: enable HAVE_LD_DEAD_CODE_DATA_ELIMINATION vmlinux.lds.h: use correct .init.data.* section name riscv: vmlinux-xip.lds.S: remove .alternative section riscv: move options to keep entries sorted riscv: Fix orphan section warnings caused by kernel/pi Link: https://lore.kernel.org/r/20230523165502.2592-1-jszhang@kernel.org Signed-off-by: Palmer Dabbelt <palmer@rivosinc.com>
