vfio: selftests: Add allocation assert helpers

2026-07-17T14:39:35Z

Add {malloc,calloc}_assert() helpers alongside the existing *_assert() helpers. Use them for VFIO selftest allocations that immediately assert a non-NULL result.

vfio: selftests: Introduce snprintf_assert()

2026-05-20T17:54:10Z

Introduce snprintf_assert() to protect the users of snprintf() to fail if the requested operation was truncated due to buffer limits. VFIO tests and libraries, including a new sysfs library that will be introduced by an upcoming patch, rely quite heavily on snprintf()s to build PCI sysfs paths. Having a protection against this will be helpful to prevent false test failures.

vfio: selftests: Split libvfio.h into separate header files

2025-11-28T17:58:07Z

Split out the contents of libvfio.h into separate header files, but keep libvfio.h as the top-level include that all tests can use. Put all new header files into a libvfio/ subdirectory to avoid future name conflicts in include paths when libvfio is used by other selftests like KVM. No functional change intended.
