[PATCH 2/4] selftests/x86/mxcsr: Test the MXCSR state write via ptrace

by Chang S. Bae

The ptrace buffer is in the non-compacted format. The MXCSR state should be written to the target thread when either SSE or AVX component is enabled. Write an MXCSR value to the target and read back. Then it is validated with the XRSTOR/XSAVE result on the current. Signed-off-by: Chang S.

[PATCH v1 0/3] kselftest/arm64: Updates to the hwcaps test

by Mark Brown

This series fixes an output formatting issue then adds a bunch more hwcaps to the hwcaps test. This includes the recently added SVE EBF16 hwcap so this requires both for-next/kselftest and for-next/sve.

[PATCH net v3 0/4] Unsync addresses from ports when stopping aggregated devices

by Benjamin Poirier

This series fixes similar problems in the bonding and team drivers. Because of missing dev_{uc,mc}_unsync() calls, addresses added to underlying devices may be leftover after the aggregated device is deleted. Add the missing calls and a few related tests. v2: * fix selftest installation, see patch 3 v3: * Split lacpdu_multicast changes to their own patch, #1 * In ndo_{add,del}_slave methods, only perform address list changes when the aggregated device is up (patches 2 & 3) * Add selftest function related to the above change (patch 4) Benjamin Poirier (4): net: bonding: Share lacpdu_mcast_addr definition net: bonding: Unsync device addresses on ndo_stop net: team: Unsync device addresses on ndo_stop net: Add tests for bonding and team address list management MAINTAINERS | 1 + drivers/net/bonding/bond_3ad.c | 5 +- drivers/net/bonding/bond_main.c | 57 +++++---- drivers/net/team/team.c | 24 +++- include/net/bond_3ad.h | 2 - include/net/bonding.h | 3 + tools/testing/selftests/Makefile | 1 + .../selftests/drivers/net/bonding/Makefile | 5 +- .../selftests/drivers/net/bonding/config | 1 + .../drivers/net/bonding/dev_addr_lists.sh | 109 ++++++++++++++++++ .../selftests/drivers/net/bonding/lag_lib.sh | 61 ++++++++++ .../selftests/drivers/net/team/Makefile | 6 + .../testing/selftests/drivers/net/team/config | 3 + .../drivers/net/team/dev_addr_lists.sh | 51 ++++++++ 14 files changed, 297 insertions(+), 32 deletions(-) create mode 100755 tools/testing/selftests/drivers/net/bonding/dev_addr_lists.sh create mode 100644 tools/testing/selftests/drivers/net/bonding/lag_lib.sh create mode 100644 tools/testing/selftests/drivers/net/team/Makefile create mode 100644 tools/testing/selftests/drivers/net/team/config create mode 100755 tools/testing/selftests/drivers/net/team/dev_addr_lists.sh -- 2.37.2

[PATCH net-next 0/8] add tc-testing test cases

by Zhengchao Shao

For this patchset, test cases of the ctinfo, gate, and xt action modules are added to the tc-testing test suite. Also add deleting test for connmark, ife, nat, sample and tunnel_key action modules.

[PATCH v13 0/3] Add TDX Guest Attestation support

by Kuppuswamy Sathyanarayanan

Hi All, Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious hosts and some physical attacks. VM guest with TDX support is called as a TDX Guest. In TDX guest, attestation process is used to verify the TDX guest trustworthiness to other entities before provisioning secrets to the guest. For example, a key server may request for attestation before releasing the encryption keys to mount the encrypted rootfs or secondary drive. This patch set adds attestation support for the TDX guest. Details about the TDX attestation process and the steps involved are explained in the commit log of Patch 1/3 or in Documentation/x86/tdx.rst (added by patch 3/3). Following are the details of the patch set: Patch 1/3 -> Adds TDREPORT support. Patch 2/3 -> Adds selftest support for TDREPORT feature. Patch 3/3 -> Add attestation related documentation. Commit log history is maintained in the individual patches.

[PATCH net-next,v3 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 and Victor 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 net-next 0/5] mptcp: allow privileged operations from user ns & cleanup

by Matthieu Baerts

This series allows privileged Netlink operations from user namespaces. When a non-root user configures MPTCP endpoints, the memory allocation is now accounted to this user. See patches 4 and 5. Apart from that, there are some cleanup: - Patch 1 adds a macro to improve code readability - Patch 2 regroups similar checks all together - Patch 3 uses an explicit boolean instead of a counter to do one more check Geliang Tang (2): selftests: mptcp: move prefix tests of addr_nr_ns2 together mptcp: add do_check_data_fin to replace copied Matthieu Baerts (1): mptcp: add mptcp_for_each_subflow_safe helper Thomas Haller (2): mptcp: allow privileged operations from user namespaces mptcp: account memory allocation in mptcp_nl_cmd_add_addr() to user net/mptcp/pm_netlink.c | 22 +++++++++---------- net/mptcp/protocol.c | 13 ++++++----- net/mptcp/protocol.h | 2 ++ .../testing/selftests/net/mptcp/mptcp_join.sh | 10 ++++----- 4 files changed, 24 insertions(+), 23 deletions(-) base-commit: 03fdb11da92fde0bdc0b6e9c1c642b7414d49e8d -- 2.37.2

[PATCH net-next 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. 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 filters bpf ok 13 23c3 -
