2023-08-04selftests: mptcp: join: fix 'implicit EP' testAndrea Claudi1-2/+3

This fixes the issue trimming the whitespace in the output string and removing the double address in the expected string.

TCP might get stuck if a nonlinear skb exceeds the path MTU, icmp error contains an incorrect icmp checksum in that case. Extend the existing test for vxlan to also send at least 1MB worth of data via TCP in addition to the existing 'large icmp packet adds route exception'.

2023-08-04selftests: cgroup: fix test_kmem_basic false positivesJohannes Weiner1-0/+4
This test fails routinely in our prod testing environment, and I can reproduce it locally as well. The test allocates dcache inside a cgroup, then drops the memory limit and checks that usage drops correspondingly. The reason it fails is because dentries are freed with an RCU delay - a debugging sleep shows that usage drops as expected shortly after. Insert a 1s sleep after dropping the limit. This should be good enough, assuming that machines running those tests are otherwise not very busy.

2023-08-04kselftest/arm64: Exit streaming mode after collecting signal contextMark Brown1-1/+24
When we collect a signal context with one of the SME modes enabled we will have enabled that mode behind the compiler and libc's back so they may issue some instructions not valid in streaming mode, causing spurious failures. For the code prior to issuing the BRK to trigger signal handling we need to stay in streaming mode if we were already there since that's a part of the signal context the caller is trying to collect. Unfortunately this code includes a memset() which is likely to be heavily optimised and is likely to use FP instructions incompatible with streaming mode. We can avoid this happening by open coding the memset(), inserting a volatile assembly statement to avoid the compiler recognising what's being done and doing something in optimisation. This code is not performance critical so the inefficiency should not be an issue. After collecting the context we can simply exit streaming mode, avoiding these issues. Use a full SMSTOP for safety to prevent any issues appearing with ZA.

2023-08-02KVM: selftests: Convert x86's nested exceptions test to printf guest assertsSean Christopherson1-3/+3
Convert x86's nested exceptions test to printf-based guest asserts, and use REPORT_GUEST_ASSERT() instead of TEST_FAIL() so that output is formatted correctly. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert the MONITOR/MWAIT test to use printf guest assertsSean Christopherson1-15/+22
Convert x86's MONITOR/MWAIT test to use printf-based guest asserts. Add a macro to handle reporting failures to reduce the amount of copy+paste needed for MONITOR vs. MWAIT. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert x86's KVM paravirt test to printf style GUEST_ASSERTSean Christopherson1-4/+6
Convert x86's KVM paravirtualization test to use the printf-based GUEST_ASSERT_EQ(). Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert the Hyper-V feature test to printf style GUEST_ASSERTSean Christopherson1-10/+21
Convert x86's Hyper-V feature test to use print-based guest asserts. Opportunistically use the EQ and NE variants in a few places to capture additional information. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert the Hyper-V extended hypercalls test to printf assertsSean Christopherson1-1/+2
Convert x86's Hyper-V extended hypercalls test to use printf-based GUEST_ASSERT_EQ(). Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert x86's CPUID test to printf style GUEST_ASSERTSean Christopherson1-6/+8
Convert x86's CPUID test to use printf-based GUEST_ASSERT_EQ() so that the test prints out debug information. Note, the test previously used REPORT_GUEST_ASSERT_2(), but that was pointless because none of the guest-side code passed any parameters to the assert.

2023-08-02KVM: selftests: Convert steal_time test to printf style GUEST_ASSERTSean Christopherson1-10/+12
Convert the steal_time test to use printf-based GUEST_ASERT. Opportunistically use GUEST_ASSERT_EQ() and GUEST_ASSERT_NE() so that the test spits out debug information on failure. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert set_memory_region_test to printf-based GUEST_ASSERTSean Christopherson1-9/+14
Convert set_memory_region_test to print-based GUEST_ASSERT, using a combo of newfangled macros to report (hopefully) useful information. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert s390's tprot test to printf style GUEST_ASSERTSean Christopherson1-2/+5

2023-08-02KVM: selftests: Convert s390's memop test to printf style GUEST_ASSERTSean Christopherson1-3/+4
Convert s390's memop test to printf-based GUEST_ASSERT, and opportunistically use GUEST_FAIL() to report invalid sizes. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert the memslot performance test to printf guest assertsSean Christopherson1-2/+4
Use the printf-based GUEST_ASSERT_EQ() in the memslot perf test instead of an half-baked open code version. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sean Christopherson <[email protected]>
2023-08-02KVM: selftests: Convert ARM's vGIC IRQ test to printf style GUEST_ASSERTSean Christopherson1-1/+2
Use printf-based guest assert reporting in ARM's vGIC IRQ test. Note, this is not as innocuous as it looks! The printf-based version of GUEST_ASSERT_EQ() ensures the expressions are evaluated only once, whereas the old version did not!
