[PATCH bpf-next v10 00/23] Introduce eBPF support for HID devices

by Benjamin Tissoires

Hi, here comes the v10 of the HID-BPF series. Again, for a full explanation of HID-BPF, please refer to the last patch in this series (23/23). Hopefully we are getting closer to merging the bpf-core changes that are pre-requesite of the HID work. This revision of the series focused on those bpf-core changes with a hopefully proper way of fixing access to ctx pointers, and a few more selftests to cover those changes. Once those bpf changes are in, the HID changes are pretty much self consistent, which is a good thing, but I still wonder how we are going to merge the selftests. I'd rather have the selftests in the bpf tree to prevent any regression on bpf-core changes, but that might require some coordination between the HID and bpf trees. Anyway, let's hope we are getting closer to the end of those revisions :) Cheers, Benjamin Benjamin Tissoires (23): selftests/bpf: regroup and declare similar kfuncs selftests in an array bpf: split btf_check_subprog_arg_match in two bpf/verifier: allow all functions to read user provided context selftests/bpf: add test for accessing ctx from syscall program type bpf/btf: bump BTF_KFUNC_SET_MAX_CNT bpf/verifier: allow kfunc to return an allocated mem selftests/bpf: Add tests for kfunc returning a memory pointer HID: core: store the unique system identifier in hid_device HID: export hid_report_type to uapi HID: convert defines of HID class requests into a proper enum HID: Kconfig: split HID support and hid-core compilation HID: initial BPF implementation selftests/bpf: add tests for the HID-bpf initial implementation HID: bpf: allocate data memory for device_event BPF programs selftests/bpf/hid: add test to change the report size HID: bpf: introduce hid_hw_request() selftests/bpf: add tests for bpf_hid_hw_request HID: bpf: allow to change the report descriptor selftests/bpf: add report descriptor fixup tests selftests/bpf: Add a test for BPF_F_INSERT_HEAD samples/bpf: HID: add new hid_mouse example samples/bpf: HID: add Surface Dial example Documentation: add HID-BPF docs Documentation/hid/hid-bpf.rst | 513 +++++++++ Documentation/hid/index.rst | 1 + drivers/Makefile | 2 +- drivers/hid/Kconfig | 20 +- drivers/hid/Makefile | 2 + drivers/hid/bpf/Kconfig | 17 + drivers/hid/bpf/Makefile | 11 + drivers/hid/bpf/entrypoints/Makefile | 93 ++ drivers/hid/bpf/entrypoints/README | 4 + drivers/hid/bpf/entrypoints/entrypoints.bpf.c | 66 ++ .../hid/bpf/entrypoints/entrypoints.lskel.h | 682 ++++++++++++ drivers/hid/bpf/hid_bpf_dispatch.c | 526 ++++++++++ drivers/hid/bpf/hid_bpf_dispatch.h | 28 + drivers/hid/bpf/hid_bpf_jmp_table.c | 577 ++++++++++ drivers/hid/hid-core.c | 49 +- include/linux/bpf.h | 11 +- include/linux/bpf_verifier.h | 2 + include/linux/btf.h | 10 + include/linux/hid.h | 38 +- include/linux/hid_bpf.h | 148 +++ include/uapi/linux/hid.h | 26 +- include/uapi/linux/hid_bpf.h | 25 + kernel/bpf/btf.c | 149 ++- kernel/bpf/verifier.c | 66 +- net/bpf/test_run.c | 37 + samples/bpf/.gitignore | 2 + samples/bpf/Makefile | 27 + samples/bpf/hid_mouse.bpf.c | 134 +++ samples/bpf/hid_mouse.c | 161 +++ samples/bpf/hid_surface_dial.bpf.c | 161 +++ samples/bpf/hid_surface_dial.c | 232 ++++ tools/include/uapi/linux/hid.h | 62 ++ tools/include/uapi/linux/hid_bpf.h | 25 + tools/testing/selftests/bpf/Makefile | 2 +- tools/testing/selftests/bpf/config | 3 + tools/testing/selftests/bpf/prog_tests/hid.c | 990 ++++++++++++++++++ .../selftests/bpf/prog_tests/kfunc_call.c | 182 +++- tools/testing/selftests/bpf/progs/hid.c | 206 ++++ .../selftests/bpf/progs/kfunc_call_fail.c | 160 +++ .../selftests/bpf/progs/kfunc_call_test.c | 71 ++ 40 files changed, 5416 insertions(+), 105 deletions(-) create mode 100644 Documentation/hid/hid-bpf.rst create mode 100644 drivers/hid/bpf/Kconfig create mode 100644 drivers/hid/bpf/Makefile create mode 100644 drivers/hid/bpf/entrypoints/Makefile create mode 100644 drivers/hid/bpf/entrypoints/README create mode 100644 drivers/hid/bpf/entrypoints/entrypoints.bpf.c create mode 100644 drivers/hid/bpf/entrypoints/entrypoints.lskel.h create mode 100644 drivers/hid/bpf/hid_bpf_dispatch.c create mode 100644 drivers/hid/bpf/hid_bpf_dispatch.h create mode 100644 drivers/hid/bpf/hid_bpf_jmp_table.c create mode 100644 include/linux/hid_bpf.h create mode 100644 include/uapi/linux/hid_bpf.h create mode 100644 samples/bpf/hid_mouse.bpf.c create mode 100644 samples/bpf/hid_mouse.c create mode 100644 samples/bpf/hid_surface_dial.bpf.c create mode 100644 samples/bpf/hid_surface_dial.c create mode 100644 tools/include/uapi/linux/hid.h create mode 100644 tools/include/uapi/linux/hid_bpf.h create mode 100644 tools/testing/selftests/bpf/prog_tests/hid.c create mode 100644 tools/testing/selftests/bpf/progs/hid.c create mode 100644 tools/testing/selftests/bpf/progs/kfunc_call_fail.c -- 2.36.1

[net-next v2 0/3] seg6: add NEXT-C-SID support for SRv6 End behavior

by Andrea Mayer

The Segment Routing (SR) architecture is based on loose source routing. A list of instructions, called segments, can be added to the packet headers to influence the forwarding and processing of the packets in an SR enabled network. In SRv6 (Segment Routing over IPv6 data plane) [1], the segment identifiers (SIDs) are IPv6 addresses (128 bits) and the segment list (SID List) is carried in the Segment Routing Header (SRH). A segment may correspond to a "behavior" that is executed by a node when the packet is received. The Linux kernel currently supports a large subset of the behaviors described in [2] (e.g., End, End.X, End.T and so on). Some SRv6 scenarios (i.e.: traffic-engineering, fast-rerouting, VPN, mobile network backhaul, etc.) may require a large number of segments (i.e. up to 15). Therefore, reducing the size of the SID List is useful to minimize the impact on MTU (Maximum Transfer Unit) and to enable SRv6 on legacy hardware devices with limited processing power that can suffer from long IPv6 headers. Draft-ietf-spring-srv6-srh-compression [3] extends the SRv6 architecture by providing different mechanisms for the efficient representation (i.e. compression) of the SID List. The NEXT-C-SID mechanism described in [3] offers the possibility of encoding several SRv6 segments within a single 128 bit SID address. Such a SID address is called a Compressed SID Container. In this way, the length of the SID List can be drastically reduced. In some cases, the SRH can be omitted, as the IPv6 Destination Address can carry the whole Segment List, using its compressed representation. The NEXT-C-SID mechanism relies on the "flavors" framework defined in [2]. The flavors represent additional operations that can modify or extend a subset of the existing behaviors. In this patchset we extend the SRv6 Subsystem in order to support the NEXT-C-SID mechanism. In details the patchset is made of: - patch 1/3: add netlink_ext_ack support in parsing SRv6 behavior attributes; - patch 2/3: add NEXT-C-SID support for SRv6 End behavior; - patch 3/3: add selftest for NEXT-C-SID in SRv6 End behavior. The corresponding iproute2 patch for supporting the NEXT-C-SID in SRv6 End behavior is provided in a separated patchset. Comments, improvements and suggestions are always appreciated. Thank you all, Andrea [1] - https://datatracker.ietf.org/doc/html/rfc8754 [2] - https://datatracker.ietf.org/doc/html/rfc8986 [3] - https://datatracker.ietf.org/doc/html/draft-ietf-spring-srv6-srh-compression v1 -> v2: - rename misleading variable names and macros, using the suffix '_bits' instead of '_len', e.g. 'lcblock_len'->'lcblock_bits'; - remove unnecessary cast operations; - get rid of the 'yoda-style' syntax; - fix check for default C-SID configuration at compilation time; - add selftest for NEXT-C-SID in SRv6 End behavior.

[PATCH net-next,v2 00/18] refactor duplicate codes in the qdisc class walk function

by Zhengchao Shao

The walk implementation of most qdisc class modules is basically the same. That is, the values of count and skip are checked first. If count is greater than or equal to skip, the registered fn function is executed. Otherwise, increase the value of count. So the code can be refactored. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Last, thanks to Victor for his review. Add test cases locally and perform the test.

[PATCH v2 0/5] KVM: arm64: Enable ring-based dirty memory tracking

by Gavin Shan

This series enables the ring-based dirty memory tracking for ARM64. The feature has been available and enabled on x86 for a while. It is beneficial when the number of dirty pages is small in a checkpointing system or live migration scenario. More details can be found from fb04a1eddb1a ("KVM: X86: Implement ring-based dirty memory tracking"). The generic part has been comprehensive, meaning there isn't too much work, needed to extend it to ARM64. - PATCH[1] introduces KVM_REQ_RING_SOFT_FULL for x86 - PATCH[2] enables the feature on ARM64 - PATCH[3-5] improves kvm/selftests/dirty_log_test v1: https://lore.kernel.org/lkml/20220819005601.198436-1-gshan@redhat.com Testing ======= (1) kvm/selftests/dirty_log_test (2) Live migration by QEMU Changelog ========= v2: * Introduce KVM_REQ_RING_SOFT_FULL (Marc) * Changelog improvement (Marc) * Fix dirty_log_test without knowing host page size (Drew) Gavin Shan (5): KVM: x86: Introduce KVM_REQ_RING_SOFT_FULL KVM: arm64: Enable ring-based dirty memory tracking KVM: selftests: Use host page size to map ring buffer in dirty_log_test KVM: selftests: Clear dirty ring states between two modes in dirty_log_test KVM: selftests: Automate choosing dirty ring size in dirty_log_test Documentation/virt/kvm/api.rst | 2 +- arch/arm64/include/uapi/asm/kvm.h | 1 + arch/arm64/kvm/Kconfig | 1 + arch/arm64/kvm/arm.c | 8 +++ arch/x86/kvm/x86.c | 5 +- include/linux/kvm_host.h | 1 + tools/testing/selftests/kvm/dirty_log_test.c | 53 ++++++++++++++------ tools/testing/selftests/kvm/lib/kvm_util.c | 2 +- virt/kvm/dirty_ring.c | 4 ++ 9 files changed, 59 insertions(+), 18 deletions(-) -- 2.23.0

[PATCH -v2] lib/notifier-error-inject: fix error when writing errno to debugfs file

by Akinobu Mita

The simple attribute files do not accept a negative value since the commit 488dac0c9237 ("libfs: fix error cast of negative value in simple_attr_write()"), so we can no longer use DEFINE_SIMPLE_ATTRIBUTE() to define a file operations for errno value.
