2022-12-14bpf: prevent leak of lsm program after failed attachMilan Landaverde
In [0], we added the ability to bpf_prog_attach LSM programs to cgroups, but in our validation to make sure the prog is meant to be attached to BPF_LSM_CGROUP, we return too early if the check fails. This results in lack of decrementing prog's refcnt (through bpf_prog_put) leaving the LSM program alive past the point of the expected lifecycle. This fix allows for the decrement to take place.

2022-12-14selftests/bpf: Select CONFIG_FUNCTION_ERROR_INJECTIONSong Liu
BPF selftests require CONFIG_FUNCTION_ERROR_INJECTION to work. However, CONFIG_FUNCTION_ERROR_INJECTION is no longer 'y' by default after recent changes. As a result, we are seeing errors like the following from BPF CI: bpf_testmod_test_read() is not modifiable __x64_sys_setdomainname is not sleepable __x64_sys_getpgid is not sleepable Fix this by explicitly selecting CONFIG_FUNCTION_ERROR_INJECTION in the selftest config.

2022-12-14selftests/bpf: Fix a selftest compilation error with CONFIG_SMP=nYonghong Song
Kernel test robot reported bpf selftest build failure when CONFIG_SMP is not set. The error message looks below: >> progs/rcu_read_lock.c:256:34: error: no member named 'last_wakee' in 'struct task_struct' last_wakee = task->real_parent->last_wakee; ~~~~~~~~~~~~~~~~~ ^ 1 error generated. When CONFIG_SMP is not set, the field 'last_wakee' is not available in struct 'task_struct'. Hence the above compilation failure. To fix the issue, let us choose another field 'group_leader' which is available regardless of CONFIG_SMP set or not.

git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd Pull iommufd implementation from Jason Gunthorpe: "iommufd is the user API to control the IOMMU subsystem as it relates to managing IO page tables that point at user space memory. It takes over from drivers/vfio/vfio_iommu_type1.c (aka the VFIO container) which is the VFIO specific interface for a similar idea. We see a broad need for extended features, some being highly IOMMU device specific: - Binding iommu_domain's to PASID/SSID - Userspace IO page tables, for ARM, x86 and S390 - Kernel bypassed invalidation of user page tables - Re-use of the KVM page table in the IOMMU - Dirty page tracking in the IOMMU - Runtime Increase/Decrease of IOPTE size - PRI support with faults resolved in userspace Many of these HW features exist to support VM use cases - for instance the combination of PASID, PRI and Userspace IO Page Tables allows an implementation of DMA Shared Virtual Addressing (vSVA) within a guest. Dirty tracking enables VM live migration with SRIOV devices and PASID support allow creating "scalable IOV" devices, among other things. As these features are fundamental to a VM platform they need to be uniformly exposed to all the driver families that do DMA into VMs, which is currently VFIO and VDPA" For more background, see the extended explanations in Jason's pull request: https://lore.kernel.org/lkml/Y5dzTU8dlmXTbzoJ@nvidia.com/ * tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd: (62 commits) iommufd: Change the order of MSI setup iommufd: Improve a few unclear bits of code iommufd: Fix comment typos vfio: Move vfio group specific code into group.c vfio: Refactor dma APIs for emulated devices vfio: Wrap vfio group module init/clean code into helpers vfio: Refactor vfio_device open and close vfio: Make vfio_device_open() truly device specific vfio: Swap order of vfio_device_container_register() and open_device() vfio: Set device->group in helper function vfio: Create wrappers for group register/unregister vfio: Move the sanity check of the group to vfio_create_group() vfio: Simplify vfio_create_group() iommufd: Allow iommufd to supply /dev/vfio/vfio vfio: Make vfio_container optionally compiled vfio: Move container related MODULE_ALIAS statements into container.c vfio-iommufd: Support iommufd for emulated VFIO devices vfio-iommufd: Support iommufd for physical VFIO devices vfio-iommufd: Allow iommufd to be used in place of a container fd vfio: Use IOMMU_CAP_ENFORCE_CACHE_COHERENCY for vfio_file_enforced_coherent() ...

2022-12-14block/blk-iocost (gcc13): keep large values in a new enumJiri Slaby (SUSE)
Since gcc13, each member of an enum has the same type as the enum [1]. And that is inherited from its members. Provided: VTIME_PER_SEC_SHIFT = 37, VTIME_PER_SEC = 1LLU << VTIME_PER_SEC_SHIFT, ... AUTOP_CYCLE_NSEC = 10LLU * NSEC_PER_SEC, the named type is unsigned long. This generates warnings with gcc-13: block/blk-iocost.c: In function 'ioc_weight_prfill': block/blk-iocost.c:3037:37: error: format '%u' expects argument of type 'unsigned int', but argument 4 has type 'long unsigned int' block/blk-iocost.c: In function 'ioc_weight_show': block/blk-iocost.c:3047:34: error: format '%u' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' So split the anonymous enum with large values to a separate enum, so that they don't affect other members.

2022-12-14tracing: Fix cpumask() example typoSteven Rostedt (Google)
The sample code for using cpumask used the wrong field for the __get_cpumask() helper. It used "cpus" which is the bitmask (but would still give a proper example) instead of the "cpum" that was there to be used. Although it produces the same output, fix it, because it's an example and is confusing in how to properly use the cpumask() macro.
