[PATCH net-next 8/8] selftests: net: fdb_notify: Add a test for FDB notifications

by Petr Machata

Check that only one notification is produced for various FDB edit operations. Regarding the ip_link_add() and ip_link_master() helpers. This pattern of action plus corresponding defer is bound to come up often, and a dedicated vocabulary to capture it will be handy. tunnel_create() and vlan_create() from forwarding/lib.sh are somewhat opaque and perhaps too kitchen-sinky, so I tried to go in the opposite direction with these ones, and wrapped only the bare minimum to schedule a corresponding cleanup.

[PATCH net-next 7/8] selftests: net: lib: Add kill_process

by Petr Machata

A number of selftests run processes in the background and need to kill them afterwards. Instead for everyone to open-code the kill / wait / redirect mantra, add a helper in net/lib.sh. Convert existing open-code sites.

[PATCH net-next 6/8] selftests: net: lib: Move checks from forwarding/lib.sh here

by Petr Machata

For logging to be useful, something has to set RET and retmsg by calling ret_set_ksft_status(). There is a suite of functions to that end in forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so that every net test can use them. Existing lib.sh users might be using these same names for their functions. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

[PATCH net-next 5/8] selftests: net: lib: Move tests_run from forwarding/lib.sh here

by Petr Machata

It would be good to use the same mechanism for scheduling and dispatching general net tests as the many forwarding tests already use. To that end, move the logging helpers to net/lib.sh so that every net test can use them. Existing lib.sh users might be using the name themselves. However lib.sh is always sourced near the top of the file (checked), and whatever new definition will simply override the one provided by lib.sh.

[PATCH 0/5] Improve arm64 pkeys handling in signal delivery

by Kevin Brodsky

This series is a follow-up to Joey's Permission Overlay Extension (POE) series [1] that recently landed on mainline. The goal is to improve the way we handle the register that governs which pkeys/POIndex are accessible (POR_EL0) during signal delivery. As things stand, we may unexpectedly fail to write the signal frame on the stack because POR_EL0 is not reset before the uaccess operations. See patch 3 for more details and the main changes this series brings. A similar series landed recently for x86/MPK [2]; the present series aims at aligning arm64 with x86. Worth noting: once the signal frame is written, POR_EL0 is still set to POR_EL0_INIT, granting access to pkey 0 only. This means that a program that sets up an alternate signal stack with a non-zero pkey will need some assembly trampoline to set POR_EL0 before invoking the real signal handler, as discussed here [3]. The x86 series also added kselftests to ensure that no spurious SIGSEGV occurs during signal delivery regardless of which pkey is accessible at the point where the signal is delivered. This series adapts those kselftests to allow running them on arm64 (patch 4-5). Finally patch 2 is a clean-up following feedback on Joey's series [4]. I have tested this series on arm64 and x86_64 (booting and running the protection_keys and pkey_sighandler_tests mm kselftests). - Kevin [1] https://lore.kernel.org/linux-arm-kernel/20240822151113.1479789-1-joey.goul… [2] https://lore.kernel.org/lkml/20240802061318.2140081-1-aruna.ramakrishna@ora… [3] https://lore.kernel.org/lkml/CABi2SkWxNkP2O7ipkP67WKz0-LV33e5brReevTTtba6oK… [4] https://lore.kernel.org/linux-arm-kernel/20241015114116.GA19334@willie-the-… Cc: akpm(a)linux-foundation.org Cc: anshuman.khandual(a)arm.com Cc: aruna.ramakrishna(a)oracle.com Cc: broonie(a)kernel.org Cc: catalin.marinas(a)arm.com Cc: dave.hansen(a)linux.intel.com Cc: dave.martin(a)arm.com Cc: jeffxu(a)chromium.org Cc: joey.gouly(a)arm.com Cc: shuah(a)kernel.org Cc: will(a)kernel.org Cc: linux-kselftest(a)vger.kernel.org Cc: x86(a)kernel.org Kevin Brodsky (5): arm64: signal: Remove unused macro arm64: signal: Remove unnecessary check when saving POE state arm64: signal: Improve POR_EL0 handling to avoid uaccess failures selftests/mm: Use generic pkey register manipulation selftests/mm: Enable pkey_sighandler_tests on arm64 arch/arm64/kernel/signal.c | 92 +++++++++++++--- tools/testing/selftests/mm/Makefile | 8 +- tools/testing/selftests/mm/pkey-arm64.h | 1 + tools/testing/selftests/mm/pkey-x86.h | 2 + .../selftests/mm/pkey_sighandler_tests.c | 101 +++++++++++++----- 5 files changed, 159 insertions(+), 45 deletions(-) -- 2.43.0

[PATCH net-next v2 00/10] selftests: net: Introduce deferred commands

by Petr Machata

Recently, a defer helper was added to Python selftests. The idea is to keep cleanup commands close to their dirtying counterparts, thereby making it more transparent what is cleaning up what, making it harder to miss a cleanup, and make the whole cleanup business exception safe. All these benefits are applicable to bash as well, exception safety can be interpreted in terms of safety vs. a SIGINT. This patchset therefore introduces a framework of several helpers that serve to schedule cleanups in bash selftests. - Patch #1 has more details about the primitives being introduced. Patch #2 adds a fallback cleanup() function to lib.sh, because ideally selftests wouldn't need to introduce a dedicated cleanup function at all. - Patch #3 adds a parameter to stop_traffic(), which makes it possible to start other background processes after the traffic is started without confusing the cleanup. - Patches #4 to #10 convert a number of selftests. The goal was to convert all tests that use start_traffic / stop_traffic to the defer framework. Leftover traffic generators are a particularly painful sort of a missed cleanup. Normal unfinished cleanups can usually be cleaned up simply by rerunning the test and interrupting it early to let the cleanups run again / in full. This does not work with stop_traffic, because it is only issued at the end of the test case that starts the traffic. At the same time, leftover traffic generators influence follow-up test runs, and are hard to notice. The tests were however converted whole-sale, not just their traffic bits. Thus they form a proof of concept of the defer framework. v2: - Patch #1: - In __defer__schedule(), use ndefers in place of ${__DEFER__NJOBS[$ndefers_key]} - Patch #4: - Defer stop_traffic including the sleep. The sleep is actually necessary and v1 was wrong in that it had the sleep prior to the stop_traffic invocation. v1 (from the RFC): - Patch #1: - Added the priority defer track - Dropped defer_scoped_fn, added in_defer_scope - Extracted to a separate independent module - Patch #2: - Moved this bit to a separate patch - Patch #3: - New patch - Patch #4 (RED): - Squashed the individual RED-related patches into one - Converted the SW datapath RED selftest as well - Patch #5 (TBF): - Fully converted the selftest, not just stop_traffic - Patches #6, #7, #8, #9, #10: - New patch Petr Machata (10): selftests: net: lib: Introduce deferred commands selftests: forwarding: Add a fallback cleanup() selftests: forwarding: lib: Allow passing PID to stop_traffic() selftests: RED: Use defer for test cleanup selftests: TBF: Use defer for test cleanup selftests: ETS: Use defer for test cleanup selftests: mlxsw: qos_mc_aware: Use defer for test cleanup selftests: mlxsw: qos_ets_strict: Use defer for test cleanup selftests: mlxsw: qos_max_descriptors: Use defer for test cleanup selftests: mlxsw: devlink_trap_police: Use defer for test cleanup .../drivers/net/mlxsw/devlink_trap_policer.sh | 85 ++++---- .../drivers/net/mlxsw/qos_ets_strict.sh | 167 ++++++++-------- .../drivers/net/mlxsw/qos_max_descriptors.sh | 118 ++++------- .../drivers/net/mlxsw/qos_mc_aware.sh | 146 +++++++------- .../selftests/drivers/net/mlxsw/sch_ets.sh | 26 ++- .../drivers/net/mlxsw/sch_red_core.sh | 185 +++++++++--------- .../drivers/net/mlxsw/sch_red_ets.sh | 24 +-- .../drivers/net/mlxsw/sch_red_root.sh | 18 +- tools/testing/selftests/net/forwarding/lib.sh | 13 +- .../selftests/net/forwarding/sch_ets.sh | 7 +- .../selftests/net/forwarding/sch_ets_core.sh | 81 +++----- .../selftests/net/forwarding/sch_ets_tests.sh | 14 +- .../selftests/net/forwarding/sch_red.sh | 103 ++++------ .../selftests/net/forwarding/sch_tbf_core.sh | 91 +++------ .../net/forwarding/sch_tbf_etsprio.sh | 7 +- .../selftests/net/forwarding/sch_tbf_root.sh | 3 +- tools/testing/selftests/net/lib.sh | 3 + tools/testing/selftests/net/lib/Makefile | 2 +- tools/testing/selftests/net/lib/sh/defer.sh | 115 +++++++++++ 19 files changed, 595 insertions(+), 613 deletions(-) create mode 100644 tools/testing/selftests/net/lib/sh/defer.sh -- 2.45.0

[PATCH v3 0/5] Add support for the Idle HLT intercept feature

by Manali Shukla

The upcoming new Idle HLT Intercept feature allows for the HLT instruction execution by a vCPU to be intercepted by the hypervisor only if there are no pending V_INTR and V_NMI events for the vCPU. When the vCPU is expected to service the pending V_INTR and V_NMI events, the Idle HLT intercept won’t trigger. The feature allows the hypervisor to determine if the vCPU is actually idle and reduces wasteful VMEXITs. Presence of the Idle HLT Intercept feature is indicated via CPUID function Fn8000_000A_EDX[30]. Document for the Idle HLT intercept feature is available at [1]. [1]: AMD64 Architecture Programmer's Manual Pub. 24593, April 2024, Vol 2, 15.9 Instruction Intercepts (Table 15-7: IDLE_HLT). https://bugzilla.kernel.org/attachment.cgi?id=306250 Testing Done: - Added a selftest to test the Idle HLT intercept functionality. - Compile and functionality testing for the Idle HLT intercept selftest are only done for x86_64. - Tested SEV and SEV-ES guest for the Idle HLT intercept functionality. v2 -> v3 - Incorporated Andrew's suggestion to structure vcpu_stat_types in a way that each architecture can share the generic types and also provide its own. v1 -> v2 - Done changes in svm_idle_hlt_test based on the review comments from Sean. - Added an enum based approach to get binary stats in vcpu_get_stat() which doesn't use string to get stat data based on the comments from Sean. - Added self_halt() and cli() helpers based on the comments from Sean.

[PATCH v3 00/11] cover-letter: iommufd: Add vIOMMU infrastructure (Part-1)

by Nicolin Chen

This series introduces a new vIOMMU infrastructure and related ioctls. IOMMUFD has been using the HWPT infrastructure for all cases, including a nested IO page table support. Yet, there're limitations for an HWPT-based structure to support some advanced HW-accelerated features, such as CMDQV on NVIDIA Grace, and HW-accelerated vIOMMU on AMD. Even for a multi-IOMMU environment, it is not straightforward for nested HWPTs to share the same parent HWPT (stage-2 IO pagetable), with the HWPT infrastructure alone: a parent HWPT typically hold one stage-2 IO pagetable and tag it with only one ID in the cache entries. When sharing one large stage-2 IO pagetable across physical IOMMU instances, that one ID may not always be available across all the IOMMU instances. In other word, it's ideal for SW to have a different container for the stage-2 IO pagetable so it can hold another ID that's available. For this "different container", add vIOMMU, an additional layer to hold extra virtualization information: _______________________________________________________________________ | iommufd (with vIOMMU) | | | | [5] | | _____________ | | | | | | [1] | vIOMMU | [4] [2] | | ________________ | | _____________ ________ | | | | | [3] | | | | | | | | IOAS |<---|(HWPT_PAGING)|<---| HWPT_NESTED |<--| DEVICE | | | |________________| |_____________| |_____________| |________| | | | | | | | |_________|____________________|__________________|_______________|_____| | | | | | ______v_____ ______v_____ ___v__ | PFN storage | (paging) | | (nested) | |struct| |------------>|iommu_domain|<----|iommu_domain|<----|device| |____________| |____________| |______| The vIOMMU object should be seen as a slice of a physical IOMMU instance that is passed to or shared with a VM. That can be some HW/SW resources: - Security namespace for guest owned ID, e.g. guest-controlled cache tags - Access to a sharable nesting parent pagetable across physical IOMMUs - Virtualization of various platforms IDs, e.g. RIDs and others - Delivery of paravirtualized invalidation - Direct assigned invalidation queues - Direct assigned interrupts - Non-affiliated event reporting On a multi-IOMMU system, the vIOMMU object must be instanced to the number of the physical IOMMUs that are passed to (via devices) a guest VM, while being able to hold the shareable parent HWPT. Each vIOMMU then just needs to allocate its own individual ID to tag its own cache: ---------------------------- ---------------- | | paging_hwpt0 | | hwpt_nested0 |--->| viommu0 ------------------ ---------------- | | IDx | ---------------------------- ---------------------------- ---------------- | | paging_hwpt0 | | hwpt_nested1 |--->| viommu1 ------------------ ---------------- | | IDy | ---------------------------- As an initial part-1, add IOMMUFD_CMD_VIOMMU_ALLOC ioctl for an allocation only. Later series will add more data structures and their ioctls. As for the implementation of the series, add an IOMMU_VIOMMU_TYPE_DEFAULT type for a core-allocated-core-managed vIOMMU object, allowing drivers to simply hook a default viommu ops for viommu-based invalidation alone. And add support for driver-specific type of vIOMMU allocation, and implement that in the ARM SMMUv3 driver for a real world use case. More vIOMMU-based structs and ioctls will be introduced in the follow-up series to support vDEVICE, vIRQ (vEVENT) and VQUEUE objects.
