2025-03-15selftests/bpf: test_tunnel: Add ping helpersBastien Curutchet (eBPF Foundation)
All tests use more or less the same ping commands as final validation. Also test_ping()'s return value is checked with ASSERT_OK() while this check is already done by the SYS() macro inside test_ping(). Create helpers around test_ping() and use them in the tests to avoid code duplication. Remove the unnecessary ASSERT_OK() from the tests.

2025-03-15selftests/bpf: test_tunnel: Add generic_attach* helpersBastien Curutchet (eBPF Foundation)
A fair amount of code duplication is present among tests to attach BPF programs. Create generic_attach* helpers that attach BPF programs to a given interface. Use ASSERT_OK_FD() instead of ASSERT_GE() to check fd's validity. Use these helpers in all the available tests.

2025-03-14cxl/pmem: debug invalid serial number dataYuquan Wang
In a nvdimm interleave-set each device with an invalid or zero serial number may cause pmem region initialization to fail, but in cxl case such device could still set cookies of nd_interleave_set and create a nvdimm pmem region. This adds the validation of serial number in cxl pmem region creation. The event of no serial number would cause to fail to set the cookie and pmem region. For cxl-test to work properly, always +1 on mock device's serial number.

2025-03-14acpi/ghes, cxl/pci: Process CXL CPER Protocol ErrorsSmita Koralahalli
When PCIe AER is in FW-First, OS should process CXL Protocol errors from CPER records. Introduce support for handling and logging CXL Protocol errors. The defined trace events cxl_aer_uncorrectable_error and cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them to trace FW-First Protocol errors. Since the CXL code is required to be called from process context and GHES is in interrupt context, use workqueues for processing. Similar to CXL CPER event handling, use kfifo to handle errors as it simplifies queue processing by providing lock free fifo operations. Add the ability for the CXL sub-system to register a workqueue to process CXL CPER protocol errors.

2025-03-14selftests: drv-net: fix merge conflicts resolutionMatthieu Baerts (NGI0)
After the recent merge between net-next and net, I got some conflicts on my side because the merge resolution was different from Stephen's one [1] I applied on my side in the MPTCP tree. It looks like the code that is now in net-next is using the old way to retrieve the local and remote addresses. This patch is now using the new way, like what was in Stephen's email [1]. Also, in get_interface_info(), there were no conflicts in this area, because that was new code from 'net', but a small adaptation was needed there as well to get the remote address.

2025-03-12rseq/selftests: Ensure the rseq ABI TLS is actually 1024 bytesMichael Jeanson
Adding the aligned(1024) attribute to the definition of __rseq_abi did not increase its size to 1024, for this attribute to impact the size of __rseq_abi it would need to be added to the declaration of 'struct rseq_abi'. We only want to increase the size of the TLS allocation to ensure registration will succeed with future extended ABI. Use a union with a dummy member to ensure we allocate 1024 bytes.

2025-03-10selftests: drv-net: add xdp cases for ping.pyTaehee Yoo
ping.py has 3 cases, test_v4, test_v6 and test_tcp. But these cases are not executed on the XDP environment. So, it adds XDP environment, existing tests(test_v4, test_v6, and test_tcp) are executed too on the below XDP environment. So, it adds XDP cases. 1. xdp-generic + single-buffer 2. xdp-generic + multi-buffer 3. xdp-native + single-buffer 4. xdp-native + multi-buffer 5. xdp-offload It also makes test_{v4 | v6 | tcp} sending large size packets. this may help to check whether multi-buffer is working or not. Note that the physical interface may be down and then up when xdp is attached or detached. This takes some period to activate traffic. So sleep(10) is added if the test interface is the physical interface. netdevsim and veth type interfaces skip sleep.
