Message-ID: <cover.1750787928.git.nicolinc@nvidia.com> Date: Tue, 24 Jun 2025 11:00:44 -0700 From: Nicolin Chen <nicolinc@...dia.com> To: <jgg@...dia.com>, <kevin.tian@...el.com> CC: <shuah@...nel.org>, <joao.m.martins@...cle.com>, <steven.sistare@...cle.com>, <iommu@...ts.linux.dev>, <linux-kselftest@...r.kernel.org>, <linux-kernel@...r.kernel.org>, <thomas.weissschuh@...utronix.de> Subject: [PATCH rc v2 0/4] Fix iommufd selftest FAIL and warnings with v6.16 A few selftest harness changes being merged to v6.16, which exposed some bugs and vulnerabilities in the iommufd selftest code. Fix them properly. Note that the patch fixing the build warnings at mfd is not ideal, as it has possibly hit some corner case in the gcc: https://lore.kernel.org/all/aEi8DV+ReF3v3Rlf@nvidia.com/ This is on github: https://github.com/nicolinc/iommufd/commits/iommufd_selftest_fixes-v6.16 Changelog: v2 * Add "Reviewed-by" from Jason * Only use kfree() in the teardown() * Add an mmap_buffer_size for readability v1 https://lore.kernel.org/all/cover.1750049883.git.nicolinc@nvidia.com/ Thanks Nicolin Nicolin Chen (4): iommufd/selftest: Fix iommufd_dirty_tracking with large hugepage sizes iommufd/selftest: Add missing close(mfd) in memfd_mmap() iommufd/selftest: Add asserts testing global mfd iommufd/selftest: Fix build warnings due to uninitialized mfd tools/testing/selftests/iommu/iommufd_utils.h | 9 ++++- tools/testing/selftests/iommu/iommufd.c | 40 ++++++++++++++----- 2 files changed, 36 insertions(+), 13 deletions(-) -- 2.43.0
