[PATCH v4 0/4] arm64/sme: ptrace support for TPIDR2_EL0

by Mark Brown

When SME was initially merged we did not add support for TPIDR2_EL0 to the ptrace interface, creating difficulties for debuggers in accessing lazy save state for ZA. This series implements that support, extending the existing NT_ARM_TLS regset to support the register when available, and adds kselftest coverage for the existing and new NT_ARM_TLS functionality. Existing programs that query the size of the register set will be able to observe the increased size of the register set. Programs that assume the register set is single register will see no change. On systems that do not support SME TPIDR2_EL0 will read as 0 and writes will be ignored, support for SME should be queried via hwcaps as normal. v4: - Rebase onto v6.0-rc3. v3: - Fix copyright date on test program. v2: - Rebase onto v6.0-rc1.

[PATCH v17 00/12] bpf: Add kfuncs for PKCS#7 signature verification

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> One of the desirable features in security is the ability to restrict import of data to a given system based on data authenticity. If data import can be restricted, it would be possible to enforce a system-wide policy based on the signing keys the system owner trusts. This feature is widely used in the kernel. For example, if the restriction is enabled, kernel modules can be plugged in only if they are signed with a key whose public part is in the primary or secondary keyring. For eBPF, it can be useful as well. For example, it might be useful to authenticate data an eBPF program makes security decisions on. After a discussion in the eBPF mailing list, it was decided that the stated goal should be accomplished by introducing four new kfuncs: bpf_lookup_user_key() and bpf_lookup_system_key(), for retrieving a keyring with keys trusted for signature verification, respectively from its serial and from a pre-determined ID; bpf_key_put(), to release the reference obtained with the former two kfuncs, bpf_verify_pkcs7_signature(), for verifying PKCS#7 signatures. Other than the key serial, bpf_lookup_user_key() also accepts key lookup flags, that influence the behavior of the lookup. bpf_lookup_system_key() accepts pre-determined IDs defined in include/linux/verification.h. bpf_key_put() accepts the new bpf_key structure, introduced to tell whether the other structure member, a key pointer, is valid or not. The reason is that verify_pkcs7_signature() also accepts invalid pointers, set with the pre-determined ID, to select a system-defined keyring. key_put() must be called only for valid key pointers. Since the two key lookup functions allocate memory and one increments a key reference count, they must be used in conjunction with bpf_key_put(). The latter must be called only if the lookup functions returned a non-NULL pointer. The verifier denies the execution of eBPF programs that don't respect this rule. The two key lookup functions should be used in alternative, depending on the use case. While bpf_lookup_user_key() provides great flexibility, it seems suboptimal in terms of security guarantees, as even if the eBPF program is assumed to be trusted, the serial used to obtain the key pointer might come from untrusted user space not choosing one that the system administrator approves to enforce a mandatory policy. bpf_lookup_system_key() instead provides much stronger guarantees, especially if the pre-determined ID is not passed by user space but is hardcoded in the eBPF program, and that program is signed. In this case, bpf_verify_pkcs7_signature() will always perform signature verification with a key that the system administrator approves, i.e. the primary, secondary or platform keyring. Nevertheless, key permission checks need to be done accurately. Since bpf_lookup_user_key() cannot determine how a key will be used by other kfuncs, it has to defer the permission check to the actual kfunc using the key. It does it by calling lookup_user_key() with KEY_DEFER_PERM_CHECK as needed permission. Later, bpf_verify_pkcs7_signature(), if called, completes the permission check by calling key_validate(). It does not need to call key_task_permission() with permission KEY_NEED_SEARCH, as it is already done elsewhere by the key subsystem. Future kfuncs using the bpf_key structure need to implement the proper checks as well. Finally, the last kfunc, bpf_verify_pkcs7_signature(), accepts the data and signature to verify as eBPF dynamic pointers, to minimize the number of kfunc parameters, and the keyring with keys for signature verification as a bpf_key structure, returned by one of the two key lookup functions. bpf_lookup_user_key() and bpf_verify_pkcs7_signature() can be called only from sleepable programs, because of memory allocation and crypto operations. For example, the lsm.s/bpf attach point is suitable, fexit/array_map_update_elem is not. The correctness of implementation of the new kfuncs and of their usage is checked with the introduced tests. The patch set includes a patch from another author (dependency) for sake of completeness. It is organized as follows. Patch 1 from KP Singh allows kfuncs to be used by LSM programs. Patch 2 splits is_dynptr_reg_valid_init() and introduces is_dynptr_type_expected(), to know more precisely the cause of a negative result of a dynamic pointer check. Patch 3 allows dynamic pointers to be used as kfunc parameters. Patch 4 exports bpf_dynptr_get_size(), to obtain the real size of data carried by a dynamic pointer. Patch 5 makes available for new eBPF kfuncs and programs some key-related definitions. Patch 6 introduces the bpf_lookup_*_key() and bpf_key_put() kfuncs. Patch 7 introduces the bpf_verify_pkcs7_signature() kfunc. Patch 8 changes the testing kernel configuration to compile everything as built-in. Finally, patches 9-12 introduce the tests. Changelog v16: - Remove comments in include/linux/key.h for KEY_LOOKUP_* - Change kmalloc() flag from GFP_ATOMIC to GFP_KERNEL in bpf_lookup_user_key(), as the kfunc needs anyway to be sleepable (suggested by Kumar) - Test passing a dynamic pointer with NULL data to bpf_verify_pkcs7_signature() (suggested by Kumar) v15: - Add kfunc_dynptr_param test to deny list for s390x v14: - Explain that is_dynptr_type_expected() will be useful also for BTF (suggested by Joanne) -

Parse kernel module in user space and pass raw PKCS#7 signature to the eBPF program for signature verification v3: - Rename bpf_verify_signature() back to bpf_verify_pkcs7_signature() to avoid managing different parameters for each signature verification function in one helper (suggested by Daniel) - Use dynamic pointers and export bpf_dynptr_get_size() (suggested by Alexei) - Introduce bpf_request_key_by_id() to give more flexibility to the caller of bpf_verify_pkcs7_signature() to retrieve the appropriate keyring (suggested by Alexei) - Fix test by reordering the gcc command line, always compile sign-file - Improve helper support check mechanism in the test v2: - Rename bpf_verify_pkcs7_signature() to a more generic bpf_verify_signature() and pass the signature type (suggested by KP) - Move the helper and prototype declaration under #ifdef so that user space can probe for support for the helper (suggested by Daniel) - Describe better the keyring types (suggested by Daniel) - Include linux/bpf.h instead of vmlinux.h to avoid implicit or redeclaration - Make the test selfcontained (suggested by Alexei) v1: - Don't define new map flag but introduce simple wrapper of verify_pkcs7_signature() (suggested by Alexei and KP) KP Singh (1): bpf: Allow kfuncs to be used in LSM programs Roberto Sassu (12): btf: Export bpf_dynptr definition bpf: Move dynptr type check to is_dynptr_type_expected() btf: Allow dynamic pointer parameters in kfuncs bpf: Export bpf_dynptr_get_size() KEYS: Move KEY_LOOKUP_ to include/linux/key.h and define KEY_LOOKUP_ALL bpf: Add bpf_lookup_*_key() and bpf_key_put() kfuncs bpf: Add bpf_verify_pkcs7_signature() kfunc selftests/bpf: Compile kernel with everything as built-in selftests/bpf: Add verifier tests for bpf_lookup_*_key() and bpf_key_put() selftests/bpf: Add additional tests for bpf_lookup_*_key() selftests/bpf: Add test for bpf_verify_pkcs7_signature() kfunc selftests/bpf: Add tests for dynamic pointers parameters in kfuncs include/linux/bpf.h | 9 + include/linux/bpf_verifier.h | 5 + include/linux/btf.h | 9 + include/linux/key.h | 6 + include/linux/verification.h | 8 + kernel/bpf/btf.c | 34 ++ kernel/bpf/helpers.c | 4 +- kernel/bpf/verifier.c | 35 +- kernel/trace/bpf_trace.c | 180 ++++++++ security/keys/internal.h | 2 -

[PATCH net-next,v3 01/18] net/sched: sch_api: add helper for tc qdisc walker stats dump

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 we can reconstruct them.

[PATCH v5 0/3] Introduce KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ macros

by Maíra Canal

Currently, in order to compare memory blocks in KUnit, the KUNIT_EXPECT_EQ or KUNIT_EXPECT_FALSE macros are used in conjunction with the memcmp function, such as: KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); Although this usage produces correct results for the test cases, if the expectation fails the error message is not very helpful, indicating only the return of the memcmp function. Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a determined size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. The v5 doesn't have any new change, just rebasing on top of drm-misc-next. The first patch of the series introduces the KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ. The second patch adds an example of memory block expectations on the kunit-example-test.c. And the last patch replaces the KUNIT_EXPECT_EQ for KUNIT_EXPECT_MEMEQ on the existing occurrences.

[PATCH net-next,v4 0/9] refactor duplicate codes in the tc cls walk function

by Zhengchao Shao

The walk implementation of most tc cls 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. Then use helper function to replace the code of each cls module in alphabetical order. The walk function is invoked during dump. Therefore, test cases related to the tdc filter need to be added. Last, thanks to Jamal, Victor and Wang for their review. Add test cases locally and perform the test. The test results are listed below: ./tdc.py -e 0811 ok 1 0811 - Add multiple basic filter with cmp ematch u8/link layer and default action and dump them ./tdc.py -e 5129 ok 1 5129 - List basic filters ./tdc.py -c bpf-filter ok 1 23c3 -

[PATCH] selftests/kvm: Use num_vcpus when testing ICR in the xapic_state_test

by Gautam Menghani

A TODO in xapic_state_test asks to use number of vCPUs instead of vcpu.id + 1 in test_icr(). This patch adds support to get the number of vCPUs from the VM created and use it.

[PATCH net-next,v2 01/18] net/sched: sch_api: add helper for tc qdisc walker stats dump

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 we can reconstruct them.

[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 v2 0/2] selftests/Make: Recursively build TARGETS list

by Dmitry Safonov

Version 2 changes: - fix `make install` in sub-directories with TARGETS, but with no TEST_LIST defined, i.e. selftests/net directory (reported-by: kernel test robot <yujie.liu(a)intel.com>) - vfork_exec selftest is about to be reverted, don't add .gitignore entry From [1]: > Please look into a wayto invoke all of them instead of adding individual > net/* to the main Makefile. This list seems to be growing. :) I might have misunderstood what was suggested... Here is an attempt to let sub-selftests define their own $(TARGETS) directories.

[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. The test results are listed below: ./tdc.py -c cake ok 1 1212 - Create CAKE with default setting ok 2 3281 - Create CAKE with bandwidth limit ok 3 c940 - Create CAKE with autorate-ingress flag ok 4 2310 -

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").
