[PATCH] KVM: selftests: Add coverage of MTE system registers

by Mark Brown

Verify that a guest with MTE has access to the MTE registers. Since MTE is enabled as a VM wide capability we need to add support for doing that in the process.

[PATCH net v2 0/8] mptcp: fixes for 6.3

by Matthieu Baerts

Patch 1 fixes a possible deadlock in subflow_error_report() reported by lockdep. The report was in fact a false positive but the modification makes sense and silences lockdep to allow syzkaller to find real issues. The regression has been introduced in v5.12. Patch 2 is a refactoring needed to be able to fix the two next issues. It improves the situation and can be backported up to v6.0. Patches 3 and 4 fix UaF reported by KASAN. It fixes issues potentially visible since v5.7 and v5.19 but only reproducible until recently (v6.0). These two patches depend on patch 2/7. Patch 5 fixes the order of the printed values: expected vs seen values. The regression has been introduced recently: v6.3-rc1. Patch 6 adds missing ro_after_init flags. A previous patch added them for other functions but these two have been missed. This previous patch has been backported to stable versions (up to v5.12) so probably better to do the same here. Patch 7 fixes tcp_set_state() being called twice in a row since v5.10. Patch 8 fixes another lockdep false positive issue but this time in MPTCP PM code. Same here, some modifications in the code has been made to silence this issue and help finding real ones later. This issue can be seen since v6.2. Note that checkpatch.pl is now complaining about the "Closes" tag but discussions are ongoing to add an exception: https://lore.kernel.org/all/a27480c5-c3d4-b302-285e-323df0349b8f@tessares.n… Signed-off-by: Matthieu Baerts <matthieu.baerts(a)tessares.net> --- Changes in v2: - Patches 3 and 4 have been modified to fix the issue reported on netdev - Patch 8 has been added - Rebased - Link to v1: https://lore.kernel.org/r/20230227-upstream-net-20230227-mptcp-fixes-v1-0-0… --- Geliang Tang (1): mptcp: add ro_after_init for tcp{,v6}_prot_override Matthieu Baerts (2): selftests: mptcp: userspace pm: fix printed values mptcp: avoid setting TCP_CLOSE state twice Paolo Abeni (5): mptcp: fix possible deadlock in subflow_error_report mptcp: refactor passive socket initialization mptcp: use the workqueue to destroy unaccepted sockets mptcp: fix UaF in listener shutdown mptcp: fix lockdep false positive in mptcp_pm_nl_create_listen_socket() net/mptcp/pm_netlink.c | 16 +++ net/mptcp/protocol.c | 64 +++++------ net/mptcp/protocol.h | 6 +- net/mptcp/subflow.c | 128 +++++++--------------- tools/testing/selftests/net/mptcp/userspace_pm.sh | 2 +- 5 files changed, 95 insertions(+), 121 deletions(-) --- base-commit: 67eeadf2f95326f6344adacb70c880bf2ccff57b change-id: 20230227-upstream-net-20230227-mptcp-fixes-cc78f3a2f5b2 Best regards, -- Matthieu Baerts <matthieu.baerts(a)tessares.net>

[PATCH v2 00/17] Add iommufd physical device operations for replace and alloc hwpt

by Jason Gunthorpe

This is the basic functionality for iommufd to support iommufd_device_replace() and IOMMU_HWPT_ALLOC for physical devices. iommufd_device_replace() allows changing the HWPT associated with the device to a new IOAS or HWPT. Replace does this in way that failure leaves things unchanged, and utilizes the iommu iommu_group_replace_domain() API to allow the iommu driver to perform an optional non-disruptive change. IOMMU_HWPT_ALLOC allows HWPTs to be explicitly allocated by the user and used by attach or replace. At this point it isn't very useful since the HWPT is the same as the automatically managed HWPT from the IOAS. However a following series will allow userspace to customize the created HWPT. The implementation is complicated because we have to introduce some per-iommu_group memory in iommufd and redo how we think about multi-device groups to be more explicit. This solves all the locking problems in the prior attempts. This series is infrastructure work for the following series which: - Add replace for attach - Expose replace through VFIO APIs - Implement driver parameters for HWPT creation (nesting) Once review of this is complete I will keep it on a side branch and accumulate the following series when they are ready so we can have a stable base and make more incremental progress. When we have all the parts together to get a full implementation it can go to Linus. I have this on github: https://github.com/jgunthorpe/linux/commits/iommufd_hwpt v2: - Use WARN_ON for the igroup->group test and move that logic to a function iommufd_group_try_get() - Change igroup->devices to igroup->device list Replace will need to iterate over all attached idevs - Rename to iommufd_group_setup_msi() - New patch to export iommu_get_resv_regions() - New patch to use per-device reserved regions instead of per-group regions - Split out the reorganizing of iommufd_device_change_pt() from the replace patch - Replace uses the per-dev reserved regions - Use stdev_id in a few more places in the selftest - Fix error handling in IOMMU_HWPT_ALLOC - Clarify comments - Rebase on v6.3-rc1 v1: https://lore.kernel.org/all/0-v1-7612f88c19f5+2f21-iommufd_alloc_jgg@nvidia… Cc: Nicolin Chen <nicolinc(a)nvidia.com> Cc: Yi Liu <yi.l.liu(a)intel.com> Cc: kvm(a)vger.kernel.org Signed-off-by: Jason Gunthorpe <jgg(a)nvidia.com> Jason Gunthorpe (15): iommufd: Move isolated msi enforcement to iommufd_device_bind() iommufd: Add iommufd_group iommufd: Replace the hwpt->devices list with iommufd_group iommu: Export iommu_get_resv_regions() iommufd: Keep track of each device's reserved regions instead of groups iommufd: Use the iommufd_group to avoid duplicate MSI setup iommufd: Make sw_msi_start a group global iommufd: Move putting a hwpt to a helper function iommufd: Add enforced_cache_coherency to iommufd_hw_pagetable_alloc() iommufd: Reorganize iommufd_device_attach into iommufd_device_change_pt iommufd: Add iommufd_device_replace() iommufd: Make destroy_rwsem use a lock class per object type iommufd: Add IOMMU_HWPT_ALLOC iommufd/selftest: Return the real idev id from selftest mock_domain iommufd/selftest: Add a selftest for IOMMU_HWPT_ALLOC Nicolin Chen (2): iommu: Introduce a new iommu_group_replace_domain() API iommufd/selftest: Test iommufd_device_replace() drivers/iommu/iommu-priv.h | 10 + drivers/iommu/iommu.c | 41 +- drivers/iommu/iommufd/device.c | 498 +++++++++++++----- drivers/iommu/iommufd/hw_pagetable.c | 96 +++- drivers/iommu/iommufd/io_pagetable.c | 25 +- drivers/iommu/iommufd/iommufd_private.h | 51 +- drivers/iommu/iommufd/iommufd_test.h | 6 + drivers/iommu/iommufd/main.c | 17 +- drivers/iommu/iommufd/selftest.c | 40 ++ include/linux/iommufd.h | 1 + include/uapi/linux/iommufd.h | 26 + tools/testing/selftests/iommu/iommufd.c | 64 ++- .../selftests/iommu/iommufd_fail_nth.c | 52 +- tools/testing/selftests/iommu/iommufd_utils.h | 61 ++- 14 files changed, 789 insertions(+), 199 deletions(-) create mode 100644 drivers/iommu/iommu-priv.h base-commit: 4ed4791afb34c61650b17407846174a72e4034f4 -- 2.39.2
