[PATCH v3 0/5] Increase mseal test coverage

by jeffxu＠chromium.org

From: Jeff Xu <jeffxu(a)chromium.org> This series increase the test coverage of mseal_test by: Add check for vma_size, prot, and error code for existing tests. Add more testcases for madvise, munmap, mmap and mremap to cover sealing in different scenarios. The increase test coverage hopefully help to prevent future regression. It doesn't change any existing mm api's semantics, i.e. it will pass on linux main and 6.10 branch. Note: in order to pass this test in mm-unstable, mm-unstable must have Liam's fix on mmap [1] [1] https://lore.kernel.org/linux-kselftest/vyllxuh5xbqmaoyl2mselebij5ox7cseekj… History: V3: - no-functional change, incooperate feedback from Pedro Falcato V2: - https://lore.kernel.org/linux-kselftest/20240829214352.963001-1-jeffxu@chro… - remove the mmap fix (Liam R.

[PATCH] selftests: add file SLAB_TYPESAFE_BY_RCU recycling stressor

by Christian Brauner

Add a simple file stressor that lives directly in-tree. This will create a bunch of processes that each open 500 file descriptors and then use close_range() to close them all. Concurrently, other processes read /proc/<pid>/fd/ which rougly does f = fget_task_next(p, &fd); if (!f) break; data.mode = f->f_mode; fput(f); Which means that it'll try to get a reference to a file in another task's file descriptor table. Under heavy file load it is increasingly likely that the other task will manage to close @file and @file will be recycled due to SLAB_TYPEAFE_BY_RCU concurrently. This will trigger various warnings in the file reference counting code.

[PATCH v5 0/5] Add PSCI v1.3 SYSTEM_OFF2 support for hibernation

by David Woodhouse

The PSCI v1.3 spec (https://developer.arm.com/documentation/den0022) adds support for a SYSTEM_OFF2 function enabling a HIBERNATE_OFF state which is analogous to ACPI S4. This will allow hosting environments to determine that a guest is hibernated rather than just powered off, and ensure that they preserve the virtual environment appropriately to allow the guest to resume safely (or bump the hardware_signature in the FACS to trigger a clean reboot instead). This updates KVM to support advertising PSCI v1.3, and unconditionally enables the SYSTEM_OFF2 support when PSCI v1.3 is enabled. For the guest side, add a new SYS_OFF_MODE_POWER_OFF handler with higher priority than the EFI one, but which *only* triggers when there's a hibernation in progress. There are other ways to do this (see the commit message for more details) but this seemed like the simplest. Version 2 of the patch series splits out the psci.h definitions into a separate commit (a dependency for both the guest and KVM side), and adds definitions for the other new functions added in v1.3. It also moves the pKVM psci-relay support to a separate commit; although in arch/arm64/kvm that's actually about the *guest* side of SYSTEM_OFF2 (i.e. using it from the host kernel, relayed through nVHE). Version 3 dropped the KVM_CAP which allowed userspace to explicitly opt in to the new feature like with SYSTEM_SUSPEND, and makes it depend only on PSCI v1.3 being exposed to the guest. Version 4 is no longer RFC, as the PSCI v1.3 spec is finally published. Minor fixes from the last round of review, and an added KVM self test. Version 5 drops some of the changes which didn't make it to the final v1.3 spec, and cleans up a couple of places which still referred to it as 'alpha' or 'beta'. It also temporarily drops the guest-side patch to invoke SYSTEM_OFF2 for hibernation, pending confirmation that the final PSCI v1.3 spec just has a typo where it changed to saying that 0x1 should be passed to mean HIBERNATE_OFF, even though it's advertised as bit 0. That can be sent under separate cover, and perhaps should have been anyway. The change in question doesn't matter for any of the KVM patches, because we just treat SYSTEM_OFF2 like the existing SYSTEM_RESET2, setting a flag to indicate that it was a SYSTEM_OFF2 call, but not actually caring about the argument; that's for userspace to worry about.

[PATCH bpf-next 0/6] selftests/bpf: integrate test_tcp_check_syncookie.sh into test_progs

by Alexis Lothoré (eBPF Foundation)

Hello, this series aims to bring test_tcp_check_syncookie.sh scope into test_progs to make sure that the corresponding tests are also run automatically in CI. This script tests for bpf_tcp_{gen,check}_syncookie and bpf_skc_lookup_tcp, in different contexts (ipv4, v6 or dual, and with tc and xdp programs). Some other tests like btf_skc_cls_ingress have some overlapping tests with test_tcp_check_syncookie.sh, so this series moves the missing bits from test_tcp_check_syncookie.sh into btf_skc_cls_ingress, which is already integrated into test_progs. - the first three commits bring some minor improvements to btf_skc_cls_ingress without changing its testing scope - fourth and fifth commits bring test_tcp_check_syncookie.sh features into btf_skc_cls_ingress - last commit removes test_tcp_check_syncookie.sh The only topic for which I am not sure for this integration is the necessity or not to run the tests with different program types: test_tcp_check_syncookie.sh runs tests with both tc and xdp programs, but btf_skc_cls_ingress currently tests those helpers only with a tc program. Would it make sense to also make sure that btf_skc_cls_ingress is tested with all the programs types supported by those helpers ? The series has been tested both in CI and in a local x86_64 qemu environment: # ./test_progs -a btf_skc_cls_ingress #38/1 btf_skc_cls_ingress/conn_ipv4:OK #38/2 btf_skc_cls_ingress/conn_ipv6:OK #38/3 btf_skc_cls_ingress/conn_dual:OK #38/4 btf_skc_cls_ingress/syncookie_ipv4:OK #38/5 btf_skc_cls_ingress/syncookie_ipv6:OK #38/6 btf_skc_cls_ingress/syncookie_dual:OK #38 btf_skc_cls_ingress:OK Summary: 1/6 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Alexis Lothoré (eBPF Foundation) <alexis.lothore(a)bootlin.com> --- Alexis Lothoré (eBPF Foundation) (6): selftests/bpf: factorize conn and syncookies tests in a single runner selftests/bpf: add missing ns cleanups in btf_skc_cls_ingress selftests/bpf: get rid of global vars in btf_skc_cls_ingress selftests/bpf: add ipv4 and dual ipv4/ipv6 support in btf_skc_cls_ingress selftests/bpf: test MSS value returned with bpf_tcp_gen_syncookie selftests/bpf: remove test_tcp_check_syncookie tools/testing/selftests/bpf/.gitignore | 1 - tools/testing/selftests/bpf/Makefile | 9 +- .../selftests/bpf/prog_tests/btf_skc_cls_ingress.c | 265 +++++++++++++-------- .../selftests/bpf/progs/test_btf_skc_cls_ingress.c | 83 +++++-- .../bpf/progs/test_tcp_check_syncookie_kern.c | 167 ------------- .../selftests/bpf/test_tcp_check_syncookie.sh | 85 ------- .../selftests/bpf/test_tcp_check_syncookie_user.c | 213 ----------------- 7 files changed, 222 insertions(+), 601 deletions(-) --- base-commit: 030207b7fce8bad6827615cfc2c6592916e2c336 change-id: 20241015-syncookie-ea7686264586 Best regards, -- Alexis Lothoré, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
