[PATCH bpf-next v2 0/3] selftests/bpf: benchmark all symbols for kprobe-multi

by Menglong Dong

Add the benchmark testcase "kprobe-multi-all", which will hook all the kernel functions during the testing. This series is separated out from [1]. Changes since V1: * introduce trace_blacklist instead of copy-pasting strcmp in the 2nd patch * use fprintf() instead of printf() in 3rd patch Link: https://lore.kernel.org/bpf/20250817024607.296117-1-dongml2@chinatelecom.cn/ [1] Menglong Dong (3): selftests/bpf: move get_ksyms and get_addrs to trace_helpers.c selftests/bpf: skip recursive functions for kprobe_multi selftests/bpf: add benchmark testing for kprobe-multi-all tools/testing/selftests/bpf/bench.c | 4 + .../selftests/bpf/benchs/bench_trigger.c | 53 ++++ .../selftests/bpf/benchs/run_bench_trigger.sh | 4 +- .../bpf/prog_tests/kprobe_multi_test.c | 220 +--------------- .../selftests/bpf/progs/trigger_bench.c | 12 + tools/testing/selftests/bpf/trace_helpers.c | 234 ++++++++++++++++++ tools/testing/selftests/bpf/trace_helpers.h | 3 + 7 files changed, 311 insertions(+), 219 deletions(-) -- 2.51.0

[PATCH net] selftests: net: sort configs

by Jakub Kicinski

Sort config files for networking selftests. This should help us avoid merge conflicts between net and net-next. patchwork check will be added to prevent new issues.

[PATCH v 2/2] selftests: riscv: Add test for the Vector ptrace interface

by Yong-Xuan Wang

Add a test case that does some basic verification of the Vector ptrace interface. This forks a child process then using ptrace to inspect and manipulate the v31 register of the child.

[PATCHv3 net 1/2] bonding: fix xfrm offload feature setup on active-backup mode

by Hangbin Liu

The active-backup bonding mode supports XFRM ESP offload. However, when a bond is added using command like `ip link add bond0 type bond mode 1 miimon 100`, the `ethtool -k` command shows that the XFRM ESP offload is disabled. This occurs because, in bond_newlink(), we change bond link first and register bond device later. So the XFRM feature update in bond_option_mode_set() is not called as the bond device is not yet registered, leading to the offload feature not being set successfully. To resolve this issue, we can modify the code order in bond_newlink() to ensure that the bond device is registered first before changing the bond link parameters. This change will allow the XFRM ESP offload feature to be correctly enabled.

[PATCH 1/1] selftest/sched: skip the test if smt is not enabled

by Yifei Liu

The core scheduling is for smt enabled cpus. It is not returns failure and gives plenty of error messages and not clearly points to the smt issue if the smt is disabled. It just mention "not a core sched system" and many other messages. For example: Not a core sched system tid=210574, / tgid=210574 / pgid=210574: ffffffffffffffff Not a core sched system tid=210575, / tgid=210575 / pgid=210574: ffffffffffffffff Not a core sched system tid=210577, / tgid=210575 / pgid=210574: ffffffffffffffff (similar things many other times) In this patch, the test will first read /sys/devices/system/cpu/smt/active, if the file cannot be opened or its value is 0, the test is skipped with an explanatory message. This helps developers understand why it is skipped and avoids unnecessary attention when running the full selftest suite.

[PATCH v4 0/7] platform/chrome: Fix a possible UAF via revocable

by Tzung-Bi Shih

This is a follow-up series of [1]. It tries to fix a possible UAF in the fops of cros_ec_chardev after the underlying protocol device has gone by using revocable. The 1st patch introduces the revocable which is an implementation of ideas from the talk [2]. The 2nd and 3rd patches add test cases for revocable in Kunit and selftest. The 4th patch converts existing protocol devices to resource providers of cros_ec_device. The 5th - 7th are PoC patches for moving most revocable code to subsystem level. Miscdevice is used as it would be simpler for PoC. Note that the device driver (e.g., cros_ec_chardev) still needs to be revocable-aware. The driver needs to specify where to save the pointer and thus the resource is available in fops. - The 5th patch adds a helper for using revocable API with fops. - The 6th patch leverages the helper in miscdevice. - The 7th patch converts cros_ec_chardev to a resource consumer of cros_ec_device to fix the UAF. [1] https://lore.kernel.org/chrome-platform/20250721044456.2736300-6-tzungbi@ke… [2] https://lpc.events/event/17/contributions/1627/ v4: - Rebase onto next-20250922. - Remove the 5th patch from v3. - Add fops replacement PoC in 5th - 7th patches. v3: https://lore.kernel.org/chrome-platform/20250912081718.3827390-1-tzungbi@ke… - Rebase onto https://lore.kernel.org/chrome-platform/20250828083601.856083-1-tzungbi@ker… and next-20250912. - The 4th patch changed accordingly. v2: https://lore.kernel.org/chrome-platform/20250820081645.847919-1-tzungbi@ker… - Rename "ref_proxy" -> "revocable". - Add test cases in Kunit and selftest. v1: https://lore.kernel.org/chrome-platform/20250814091020.1302888-1-tzungbi@ke… Tzung-Bi Shih (7): revocable: Revocable resource management revocable: Add Kunit test cases selftests: revocable: Add kselftest cases platform/chrome: Protect cros_ec_device lifecycle with revocable revocable: Add fops replacement char: misc: Leverage revocable fops replacement platform/chrome: cros_ec_chardev: Secure cros_ec_device via revocable .../driver-api/driver-model/index.rst | 1 + .../driver-api/driver-model/revocable.rst | 87 ++++ MAINTAINERS | 9 + drivers/base/Kconfig | 8 + drivers/base/Makefile | 5 +- drivers/base/revocable.c | 374 ++++++++++++++++++ drivers/base/revocable_test.c | 110 ++++++ drivers/char/misc.c | 7 + drivers/platform/chrome/cros_ec.c | 5 + drivers/platform/chrome/cros_ec_chardev.c | 15 +- include/linux/miscdevice.h | 3 + include/linux/platform_data/cros_ec_proto.h | 4 + include/linux/revocable.h | 60 +++ tools/testing/selftests/Makefile | 1 + .../selftests/drivers/base/revocable/Makefile | 7 + .../drivers/base/revocable/revocable_test.c | 116 ++++++ .../drivers/base/revocable/test-revocable.sh | 39 ++ .../base/revocable/test_modules/Makefile | 10 + .../revocable/test_modules/revocable_test.c | 188 +++++++++ 19 files changed, 1047 insertions(+), 2 deletions(-) create mode 100644 Documentation/driver-api/driver-model/revocable.rst create mode 100644 drivers/base/revocable.c create mode 100644 drivers/base/revocable_test.c create mode 100644 include/linux/revocable.h create mode 100644 tools/testing/selftests/drivers/base/revocable/Makefile create mode 100644 tools/testing/selftests/drivers/base/revocable/revocable_test.c create mode 100755 tools/testing/selftests/drivers/base/revocable/test-revocable.sh create mode 100644 tools/testing/selftests/drivers/base/revocable/test_modules/Makefile create mode 100644 tools/testing/selftests/drivers/base/revocable/test_modules/revocable_test.c -- 2.51.0.534.gc79095c0ca-goog
