When running the test suite on 32-bit architectures that use 64-bit time_t (e.g., modern armhf/i386 for Y2038 compliance), test_server_simple_timeouts fails with OSError: [Errno 22] Invalid argument. Steps to Reproduce Run autopkgtest or pytest on a 32-bit system with a 64-bit time_t kernel. Run tests/test_ssl.py::MiscSSLClientTestCase::test_server_simple_timeouts. Actual Result (logs -> https://objectstorage.prodstack5.canonical.com/swift/v1/AUTH_0f9aae918d5b4744bf7b827671c86842/autopkgtest-resolute/resolute/armhf/m/m2crypto/20260113_215730_4a505@/log.gz) E OSError: [Errno 22] Invalid argument /usr/lib/python3/dist-packages/M2Crypto/SSL/Connection.py:689: OSError The M2Crypto.SSL.timeout.timeout.pack() method uses struct.pack("ll", ...) when m2.time_t_bits() == 64. On standard 64-bit systems (x86_64), l is 8 bytes. ll = 16 bytes. (Correct) On 32-bit systems, l is 4 bytes. ll = 8 bytes. (Incorrect) The kernel expects a 16-byte struct timeval (two 64-bit integers) because of the Y2038-compliant 64-bit time_t. Passing an 8-byte structure causes setsockopt to reject the call with EINVAL. Proposed Fix: Change the packing format from "ll" to "qq" (long long). This forces 8-byte integers on all platforms, ensuring the structure is always 16 bytes when time_t is 64-bit. -- System Information: Debian Release: forky/sid APT prefers questing-updates APT policy: (500, 'questing-updates'), (500, 'questing-security'), (500, 'questing'), (100, 'questing-backports') Architecture: amd64 (x86_64) Kernel: Linux 6.17.0-8-generic (SMP w/16 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_WARN, TAINT_OOT_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
