2023-11-20selftests: mptcp: fix wait_rm_addr/sf parametersGeliang Tang
commit 9168ea02b898d3dde98b51e4bd3fb082bd438dab upstream. The second input parameter of 'wait_rm_addr/sf $1 1' is misused. If it's 1, wait_rm_addr/sf will never break, and will loop ten times, then 'wait_rm_addr/sf' equals to 'sleep 1'. This delay time is too long, which can sometimes make the tests fail. A better way to use wait_rm_addr/sf is to use rm_addr/sf_count to obtain the current value, and then pass into wait_rm_addr/sf.

2023-11-20selftests: mptcp: run userspace pm tests slowerGeliang Tang
commit f4a75e9d11001481dca005541b6dc861e1472f03 upstream.

2023-11-20selftests: pmtu.sh: fix result checkingHangbin Liu
[ Upstream commit 63e201916b27260218e528a2f8758be47f99bbf4 ] In the PMTU test, when all previous tests are skipped and the new test passes, the exit code is set to 0. However, the current check mistakenly treats this as an assignment, causing the check to pass every time. Consequently, regardless of how many tests have failed, if the latest test passes, the PMTU test will report a pass.

2023-11-20cxl/pci: Clarify devm host for memdev relative setupDan Williams
[ Upstream commit f29a824b0b6710328a78b018de3c2cfa9db65876 ] It is all too easy to get confused about @dev usage in the CXL driver stack. Before adding a new cxl_pci_probe() setup operation that has a devm lifetime dependent on @cxlds->dev binding, but also references @cxlmd->dev, and prints messages, rework the devm_cxl_add_memdev() and cxl_memdev_setup_fw_upload() function signatures to make this distinction explicit. I.e. pass in the devm context as an @host argument rather than infer it from other objects. This is in preparation for adding a devm_cxl_sanitize_setup_notifier(). Note the whitespace fixup near the change of the devm_cxl_add_memdev() signature. That uncaught typo originated in the patch that added cxl_memdev_security_init().

2023-11-20kselftest: vm: fix mdwe's mmap_FIXED test caseFlorent Revest
[ Upstream commit a27e2e2d465e4ed73371974040689ac3e78fe3ee ] I checked with the original author, the mmap_FIXED test case wasn't properly tested and fails. Currently, it maps two consecutive (non overlapping) pages and expects the second mapping to be denied by MDWE but these two pages have nothing to do with each other so MDWE is actually out of the picture here. What the test actually intended to do was to remap a virtual address using MAP_FIXED. However, this operation unmaps the existing mapping and creates a new one so the va is backed by a new page and MDWE is again out of the picture, all remappings should succeed. This patch keeps the test case to make it clear that this situation is expected to work: MDWE shouldn't block a MAP_FIXED replacement.

2023-11-20selftests/bpf: Make linked_list failure test more robustKumar Kartikeya Dwivedi
[ Upstream commit da1055b673f3baac2249571c9882ce767a0aa746 ] The linked list failure test 'pop_front_off' and 'pop_back_off' currently rely on matching exact instruction and register values. The purpose of the test is to ensure the offset is correctly incremented for the returned pointers from list pop helpers, which can then be used with container_of to obtain the real object. Hence, somehow obtaining the information that the offset is 48 will work for us. Make the test more robust by relying on verifier error string of bpf_spin_lock and remove dependence on fragile instruction index or register number, which can be affected by different clang versions used to build the selftests.

[ Upstream commit c4eee56e14fe001e1cff54f0b438a5e2d0dd7454 ] Assume that caller's 'to' offset really represents an upper boundary for the pattern search, so patterns extending past this offset are to be rejected. The old behaviour also was kind of inconsistent when it comes to fragmentation (or otherwise non-linear skbs): If the pattern started in between 'to' and 'from' offsets but extended to the next fragment, it was not found if 'to' offset was still within the current fragment. Test the new behaviour in a kselftest using iptables' string match.

The abi_test currently uses a long sized test value for enablement checks. On LE this works fine, however, on BE this results in inaccurate assert checks due to a bit being used and assuming it's value is the same on both LE and BE. Use int type for 32-bit values and long type for 64-bit values to ensure appropriate behavior on both LE and BE.

The 0.6.1 version was released in May of 2021, so should be propagated to most installations at this point. The alternative that Paolo proposed was to only skip when the add-flow is being run. This would be okay for most cases, except if a future test case is added that needs to do flow dump without an associated add (just guessing). In that case, it could also be broken and we would need additional skip logic anyway. Just draw a line in the sand now.

Except for off-by-default features, i.e. AMX, KVM's ABI for KVM_SET_XSAVE is that userspace is allowed to load xfeatures so long as they are supported by the host. This is a regression test for a combination of KVM bugs where the state saved by KVM_GET_XSAVE{2} could not be loaded via KVM_SET_XSAVE if the saved xstate_bv would load guest-unsupported xfeatures.

2023-10-06selftests/bpf: Make seen_tc* variable tests more robustDaniel Borkmann
Martin reported that on his local dev machine the test_tc_chain_mixed() fails as "test_tc_chain_mixed:FAIL:seen_tc5 unexpected seen_tc5: actual 1 != expected 0" and others occasionally, too. However, when running in a more isolated setup (qemu in particular), it works fine for him. The reason is that there is a small race-window where seen_tc* could turn into true for various test cases when there is background traffic, e.g. after the asserts they often get reset. In such case when subsequent detach takes place, unrelated background traffic could have already flipped the bool to true beforehand. Add a small helper tc_skel_reset_all_seen() to reset all bools before we do the ping test. At this point, everything is set up as expected and therefore no race can occur. All tc_{opts,links} tests continue to pass after this change.

Zero-initialize the entire test_result structure used by memslot_perf_test instead of zeroing only the fields used to guard the pr_info() calls. gcc 13.2.0 is a bit overzealous and incorrectly thinks that rbestslottime's slot_runtime may be used uninitialized.

The cost to do so is negligible, both in terms of code and runtime overhead. The only downside is that the compiler won't warn about legitimate usage of "uninitialized" data, e.g. the test could end up consuming zeros instead of useful data. However, given that the test is quite mature and unlikely to see substantial changes, the odds of introducing such bugs are relatively low, whereas being able to compile KVM selftests with -Werror detects issues on a regular basis.

2023-10-04KVM: selftests: Treat %llx like %lx when formatting guest printfSean Christopherson
Treat %ll* formats the same as %l* formats when processing printfs from the guest so that using e.g. %llx instead of %lx generates the expected output. Ideally, unexpected formats would generate compile-time warnings or errors, but it's not at all obvious how to actually accomplish that. Alternatively, guest_vsnprintf() could assert on an unexpected format, but since the vast majority of printfs are for failed guest asserts, getting *something* printed is better than nothing. E.g. before ==== Test Assertion Failure ==== x86_64/private_mem_conversions_test.c:265: mem[i] == 0 pid=4286 tid=4290 errno=4 - Interrupted system call 1 0x0000000000401c74: __test_mem_conversions at private_mem_conversions_test.c:336 2 0x00007f3aae6076da: ?? ??:0 3 0x00007f3aae32161e: ?? ??:0 Expected 0x0 at offset 0 (gpa 0x%lx), got 0x0 and after ==== Test Assertion Failure ==== x86_64/private_mem_conversions_test.c:265: mem[i] == 0 pid=5664 tid=5668 errno=4 - Interrupted system call 1 0x0000000000401c74: __test_mem_conversions at private_mem_conversions_test.c:336 2 0x00007fbe180076da: ?? ??:0 3 0x00007fbe17d2161e: ?? ??:0 Expected 0x0 at offset 0 (gpa 0x100000000), got 0xcc Fixes: e5119382499c ("KVM: selftests: Add guest_snprintf() to KVM selftests") Cc: Aaron Lewis <aaronlewis@google.com> Link: https://lore.kernel.org/r/20230921171641.3641776-1-seanjc@google.com Signed-off-by: Sean Christopherson <seanjc@google.com>
