Hi, Christian has reported that one can make a TCG guest stuck by running PRNO TRNG with a huge buffer. This series fixes this by making PRNO TRNG always end after generating 16KB.
Patch 1 is the fix, patch 2 is the test. Cc: Harald, because this may conflict with the CPACF series. Best regards, Ilya Ilya Leoshkevich (2): target/s390x: Make PRNO TRNG interruptible tests/tcg/s390x: Test PRNO TRNG interruptibility target/s390x/tcg/crypto_helper.c | 25 +++++++++--- tests/tcg/s390x/Makefile.target | 1 + tests/tcg/s390x/prno-trng.c | 67 ++++++++++++++++++++++++++++++++ 3 files changed, 87 insertions(+), 6 deletions(-) create mode 100644 tests/tcg/s390x/prno-trng.c -- 2.55.0
