[PATCH] selftests/seccomp: Add test for SECCOMP_RET_LOG semantics

by Jiwoo Ahn

Add a selftest to verify that SECCOMP_RET_LOG actually emits a kernel log entry when a system call is triggered under a seccomp filter. The test installs a minimal seccomp BPF program returning SECCOMP_RET_LOG and checks that a corresponding seccomp message including the process PID appears in /dev/kmsg. If /dev/kmsg is inaccessible or logging is disabled, the test is skipped.

[PATCH net-next v12 00/12] vsock: add namespace support to vhost-vsock and loopback

by Bobby Eshleman

This series adds namespace support to vhost-vsock and loopback. It does not add namespaces to any of the other guest transports (virtio-vsock, hyperv, or vmci). The current revision supports two modes: local and global. Local mode is complete isolation of namespaces, while global mode is complete sharing between namespaces of CIDs (the original behavior). The mode is set using /proc/sys/net/vsock/ns_mode. Modes are per-netns and write-once. This allows a system to configure namespaces independently (some may share CIDs, others are completely isolated). This also supports future possible mixed use cases, where there may be namespaces in global mode spinning up VMs while there are mixed mode namespaces that provide services to the VMs, but are not allowed to allocate from the global CID pool (this mode is not implemented in this series). If a socket or VM is created when a namespace is global but the namespace changes to local, the socket or VM will continue working normally. That is, the socket or VM assumes the mode behavior of the namespace at the time the socket/VM was created. The original mode is captured in vsock_create() and so occurs at the time of socket(2) and accept(2) for sockets and open(2) on /dev/vhost-vsock for VMs. This prevents a socket/VM connection from suddenly breaking due to a namespace mode change. Any new sockets/VMs created after the mode change will adopt the new mode's behavior. Additionally, added tests for the new namespace features: tools/testing/selftests/vsock/vmtest.sh 1..28 ok 1 vm_server_host_client ok 2 vm_client_host_server ok 3 vm_loopback ok 4 ns_host_vsock_ns_mode_ok ok 5 ns_host_vsock_ns_mode_write_once_ok ok 6 ns_global_same_cid_fails ok 7 ns_local_same_cid_ok ok 8 ns_global_local_same_cid_ok ok 9 ns_local_global_same_cid_ok ok 10 ns_diff_global_host_connect_to_global_vm_ok ok 11 ns_diff_global_host_connect_to_local_vm_fails ok 12 ns_diff_global_vm_connect_to_global_host_ok ok 13 ns_diff_global_vm_connect_to_local_host_fails ok 14 ns_diff_local_host_connect_to_local_vm_fails ok 15 ns_diff_local_vm_connect_to_local_host_fails ok 16 ns_diff_global_to_local_loopback_local_fails ok 17 ns_diff_local_to_global_loopback_fails ok 18 ns_diff_local_to_local_loopback_fails ok 19 ns_diff_global_to_global_loopback_ok ok 20 ns_same_local_loopback_ok ok 21 ns_same_local_host_connect_to_local_vm_ok ok 22 ns_same_local_vm_connect_to_local_host_ok ok 23 ns_mode_change_connection_continue_vm_ok ok 24 ns_mode_change_connection_continue_host_ok ok 25 ns_mode_change_connection_continue_both_ok ok 26 ns_delete_vm_ok ok 27 ns_delete_host_ok ok 28 ns_delete_both_ok SUMMARY: PASS=28 SKIP=0 FAIL=0 Dependent on series: https://lore.kernel.org/all/20251108-vsock-selftests-fixes-and-improvements… Thanks again for everyone's help and reviews!

This series adds namespace support to vhost-vsock and loopback. It does not add namespaces to any of the other guest transports (virtio-vsock, hyperv, or vmci). The current revision supports two modes: local and global. Local mode is complete isolation of namespaces, while global mode is complete sharing between namespaces of CIDs (the original behavior). The mode is set using the parent namespace's /proc/sys/net/vsock/child_ns_mode and inherited when a new namespace is created. The mode of the current namespace can be queried by reading /proc/sys/net/vsock/ns_mode. The mode can not change after the namespace has been created. Modes are per-netns. This allows a system to configure namespaces independently (some may share CIDs, others are completely isolated). This also supports future possible mixed use cases, where there may be namespaces in global mode spinning up VMs while there are mixed mode namespaces that provide services to the VMs, but are not allowed to allocate from the global CID pool (this mode is not implemented in this series).

[PATCH] selftests/mm: ksm_tests: skip when not run as root

by Sun Jian

ksm_tests writes KSM sysfs knobs under /sys/kernel/mm/ksm, which requires root privileges. When run unprivileged, it fails with permission errors and reports FAIL, which is misleading. Skip the test early when not run as root to avoid false failures.

[PATCH net-next v2 0/6] selftests: drv-net: gro: enable HW GRO and LRO testing

by Jakub Kicinski

Add support for running our existing GRO test against HW GRO and LRO implementation. The first 3 patches are just ksft lib nice-to-haves, and patch 4 cleans up the existing gro Python. Patches 5 and 6 are of most practical interest. The support reconfiguring the NIC to disable SW GRO and enable HW GRO and LRO. Additionally last patch breaks up the existing GRO cases to track HW compliance at finer granularity. v2: - fix restoring all features - apply the generic XDP hack selectively (print a msg when it happens) - a lot of small tweaks and 4 extra patches v1: https://lore.kernel.org/20251128005242.2604732-1-kuba@kernel.org Jakub Kicinski (6): selftests: net: py: teach ksft_pr() multi-line safety selftests: net: py: teach cmd() how to print itself selftests: drv-net: gro: use cmd print selftests: drv-net: gro: improve feature config selftests: drv-net: gro: run the test against HW GRO and LRO selftests: drv-net: gro: break out all individual test cases tools/testing/selftests/drivers/net/gro.c | 399 +++++++++++--------- tools/testing/selftests/drivers/net/gro.py | 158 ++++++-- tools/testing/selftests/net/lib/py/ksft.py | 29 +- tools/testing/selftests/net/lib/py/utils.py | 23 ++ 4 files changed, 406 insertions(+), 203 deletions(-) -- 2.52.0

[PATCH 0/2] selftests: Centralize kselftest headers to avoid relative includes

by Bala-Vignesh-Reddy

This series centralize the handling of kselftest.h and kselftest_harness.h includes in selftests, replacing relative paths with a non-relative approach using shared -I path. Patch-1 updates the build files (Makefile and lib.mk) and include CFLAGS in sync/Makefile to resolve not found error Patch-2 applies bulk source change (Patch 2 is large but it is replaced automatically) Checked the changes with gcc-13.32 and clang 18.1 Suggested-by: Andrew Morton <akpm(a)linux-foundation.org> Link:
