2024-10-11ftrace/selftest: Test combination of function_graph tracer and function profilerSteven Rostedt
Masami reported a bug when running function graph tracing then the function profiler. The following commands would cause a kernel crash: # cd /sys/kernel/tracing/ # echo function_graph > current_tracer # echo 1 > function_profile_enabled In that order. Create a test to test this two to make sure this does not come back as a regression.

2024-10-10selftests/bpf: Assert link info uprobe_multi count & path_size if unsetTyrone Wu
Add assertions in `bpf_link_info.uprobe_multi` test to verify that `count` and `path_size` fields are correctly populated when the fields are unset. This tests a previous bug where the `path_size` field was not populated when `path` and `path_size` were unset.

2024-10-10selftests/bpf: Fix cross-compiling urandom_readTony Ambardar
Linking of urandom_read and liburandom_read.so prefers LLVM's 'ld.lld' but falls back to using 'ld' if unsupported. However, this fallback discards any existing makefile macro for LD and can break cross-compilation. Fix by changing the fallback to use the target linker $(LD), passed via '-fuse-ld=' using an absolute path rather than a linker "flavour".

Add three success test cases to test the flattening of array of nested struct. For these three tests, the number of special fields in map is BTF_FIELDS_MAX, but the array is defined in structs with different nested level. Add one failure test case for the flattening as well. In the test case, the number of special fields in map is BTF_FIELDS_MAX + 1. It will make btf_parse_fields() in map_create() return -E2BIG, the creation of map will succeed, but the load of program will fail because the btf_record is invalid for the map.

2024-10-09selftests/mm: fix incorrect buffer->mirror size in hmm2 double_map testDonet Tom
The hmm2 double_map test was failing due to an incorrect buffer->mirror size. The buffer->mirror size was 6, while buffer->ptr size was 6 * PAGE_SIZE. The test failed because the kernel's copy_to_user function was attempting to copy a 6 * PAGE_SIZE buffer to buffer->mirror. Since the size of buffer->mirror was incorrect, copy_to_user failed. This patch corrects the buffer->mirror size to 6 * PAGE_SIZE.

2024-10-09selftests: sched_ext: Add sched_ext as proper selftest targetBjörn Töpel
The sched_ext selftests is missing proper cross-compilation support, a proper target entry, and out-of-tree build support. When building the kselftest suite, e.g.: make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \ TARGETS=sched_ext SKIP_TARGETS="" O=/output/foo \ -C tools/testing/selftests install or: make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \ O=/output/foo -C tools/testing/selftests install The expectation is that the sched_ext is included, cross-built, the correct toolchain is picked up, and placed into /output/foo. In contrast to the BPF selftests, the sched_ext suite does not use bpftool at test run-time, so it is sufficient to build bpftool for the build host only. Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_ext selftest. Also, remove some variables that were unused by the Makefile.

2024-10-04selftests: net: no_forwarding: fix VID for $swp2 in one_bridge_two_pvids() testKacper Ludwinski
Currently, the second bridge command overwrites the first one. Fix this by adding this VID to the interface behind $swp2. The one_bridge_two_pvids() test intends to check that there is no leakage of traffic between bridge ports which have a single VLAN - the PVID VLAN. Because of a typo, port $swp1 is configured with a PVID twice (second command overwrites first), and $swp2 isn't configured at all (and since the bridge vlan_default_pvid property is set to 0, this port will not have a PVID at all, so it will drop all untagged and priority-tagged traffic). So, instead of testing the configuration that was intended, we are testing a different one, where one port has PVID 2 and the other has no PVID. This incorrect version of the test should also pass, but is ineffective for its purpose, so fix the typo. This typo has an impact on results of the test, potentially leading to wrong conclusions regarding the functionality of a network device. The tests results: TEST: Switch ports in VLAN-aware bridge with different PVIDs: Unicast non-IP untagged [ OK ] Multicast non-IP untagged [ OK ] Broadcast non-IP untagged [ OK ] Unicast IPv4 untagged [ OK ] Multicast IPv4 untagged [ OK ] Unicast IPv6 untagged [ OK ] Multicast IPv6 untagged [ OK ] Unicast non-IP VID 1 [ OK ] Multicast non-IP VID 1 [ OK ] Broadcast non-IP VID 1 [ OK ] Unicast IPv4 VID 1 [ OK ] Multicast IPv4 VID 1 [ OK ] Unicast IPv6 VID 1 [ OK ] Multicast IPv6 VID 1 [ OK ] Unicast non-IP VID 4094 [ OK ] Multicast non-IP VID 4094 [ OK ] Broadcast non-IP VID 4094 [ OK ] Unicast IPv4 VID 4094 [ OK ] Multicast IPv4 VID 4094 [ OK ] Unicast IPv6 VID 4094 [ OK ] Multicast IPv6 VID 4094 [ OK ] Fixes: 476a4f05d9b8 ("selftests: forwarding: add a no_forwarding.sh test") Reviewed-by: Hangbin Liu <liuhangbin@gmail.com> Reviewed-by: Shuah Khan <skhan@linuxfoundation.org> Signed-off-by: Kacper Ludwinski <kac.ludwinski@icloud.com> Link: https://patch.msgid.link/20241002051016.849-1-kac.ludwinski@icloud.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The timer to wake up the system is set to expire after 5 seconds and no re-arm. If the timer remaining time is 0 second and 0 nano secomd, it means the timer expired and wake the system up. Otherwise, the system could be considered to enter the suspend state failed if there is any remaining time. After appling this patch, the test would not fail for it believes the system does not go to suspend by mistake. It now could continue to the rest part of the test after suspend.

This test was added because of a bug in verifier.c:sync_linked_regs(), upon range propagation it destroyed subreg_def marks for registers. The test is written in a way to return an upper half of a register that is affected by range propagation and must have it's subreg_def preserved.

Pull x86 kvm updates from Paolo Bonzini: "x86: - KVM currently invalidates the entirety of the page tables, not just those for the memslot being touched, when a memslot is moved or deleted. This does not traditionally have particularly noticeable overhead, but Intel's TDX will require the guest to re-accept private pages if they are dropped from the secure EPT, which is a non starter. Actually, the only reason why this is not already being done is a bug which was never fully investigated and caused VM instability with assigned GeForce GPUs, so allow userspace to opt into the new behavior. - Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10 functionality that is on the horizon) - Rework common MSR handling code to suppress errors on userspace accesses to unsupported-but-advertised MSRs This will allow removing (almost?) all of KVM's exemptions for userspace access to MSRs that shouldn't exist based on the vCPU model (the actual cleanup is non-trivial future work) - Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the 64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv) stores the entire 64-bit value at the ICR offset - Fix a bug where KVM would fail to exit to userspace if one was triggered by a fastpath exit handler - Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when there's already a pending wake event at the time of the exit - Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN (the SHUTDOWN hits the VM altogether, not the nested guest) - Overhaul the "unprotect and retry" logic to more precisely identify cases where retrying is actually helpful, and to harden all retry paths against putting the guest into an infinite retry loop - Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in the shadow MMU - Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for adding multi generation LRU support in KVM - Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled, i.e. when the CPU has already flushed the RSB - Trace the per-CPU host save area as a VMCB pointer to improve readability and cleanup the retrieval of the SEV-ES host save area - Remove unnecessary accounting of temporary nested VMCB related allocations - Set FINAL/PAGE in the page fault error code for EPT violations if and only if the GVA is valid. If the GVA is NOT valid, there is no guest-side page table walk and so stuffing paging related metadata is nonsensical - Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of emulating posted interrupt delivery to L2 - Add a lockdep assertion to detect unsafe accesses of vmcs12 structures - Harden eVMCS loading against an impossible NULL pointer deref (really truly should be impossible) - Minor SGX fix and a cleanup - Misc cleanups Generic: - Register KVM's cpuhp and syscore callbacks when enabling virtualization in hardware, as the sole purpose of said callbacks is to disable and re-enable virtualization as needed - Enable virtualization when KVM is loaded, not right before the first VM is created Together with the previous change, this simplifies a lot the logic of the callbacks, because their very existence implies virtualization is enabled - Fix a bug that results in KVM prematurely exiting to userspace for coalesced MMIO/PIO in many cases, clean up the related code, and add a testcase - Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_ the gpa+len crosses a page boundary, which thankfully is guaranteed to not happen in the current code base. Add WARNs in more helpers that read/write guest memory to detect similar bugs Selftests: - Fix a goof that caused some Hyper-V tests to be skipped when run on bare metal, i.e. NOT in a VM - Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest - Explicitly include one-off assets in .gitignore.

Misc cleanups: - Convert devm_cxl_add_root() to return using ERR_CAST() - cxl_test use dev_is_platform() instead of open coding - Remove duplicate include of header core.h in core/cdat.c - use scoped resource management to drop put_device() for cxl_port - Use scoped_guard to drop device_lock() for cxl_port - Refactor __devm_cxl_add_port() to drop gotos - Rename cxl_setup_parent_dport to cxl_dport_init_aer and cxl_dport_map_regs() to cxl_dport_map_ras() - Refactor cxl_dport_init_aer() to be more concise - Remove duplicate host_bridge->native_aer checking in cxl_dport_init_ras_reporting() - Fix comment for cxl_query_cmd()" * tag 'cxl-for-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (21 commits) cxl: Add documentation to explain the shared link bandwidth calculation cxl: Calculate region bandwidth of targets with shared upstream link cxl: Preserve the CDAT access_coordinate for an endpoint cxl: Fix comment regarding cxl_query_cmd() return data cxl: Convert cxl_internal_send_cmd() to use 'struct cxl_mailbox' as input cxl: Move mailbox related bits to the same context cxl: move cxl headers to new include/cxl/ directory cxl/region: Remove lock from memory notifier callback cxl/pci: simplify the check of mem_enabled in cxl_hdm_decode_init() cxl/pci: Check Mem_info_valid bit for each applicable DVSEC cxl/pci: Remove duplicated implementation of waiting for memory_info_valid cxl/pci: Fix to record only non-zero ranges cxl/pci: Remove duplicate host_bridge->native_aer checking cxl/pci: cxl_dport_map_rch_aer() cleanup cxl/pci: Rename cxl_setup_parent_dport() and cxl_dport_map_regs() cxl/port: Refactor __devm_cxl_add_port() to drop goto pattern cxl/port: Use scoped_guard()/guard() to drop device_lock() for cxl_port cxl/port: Use __free() to drop put_device() for cxl_port cxl: Remove duplicate included header file core.h tools/testing/cxl: Use dev_is_platform() ...
2024-09-27selftests: vDSO: align stack for O2-optimized memcpyJason A. Donenfeld
When switching on -O2, gcc generates SSE2 instructions that assume a 16-byte aligned stack, which the standalone test's start point wasn't aligning. Fix this with the usual alignment sequence.
