Subject: [PATCH v2 0/2] selftests/bpf: Fix d_path check_mem_access and drop CHECK()
Date: Fri, 06 Nov 2026 10:37:07 +0700 [thread overview]
Message-ID: <20261106-dpath-memfd-v2-0-1dc0799b4aa6@gmail.com> (raw)
Patch 1 replaces the deprecated CHECK() calls with ASSERT_*().
Patch 2 fixes check_mem_access, which creates a temp file in
/dev/shm that isn't mounted under vmtest.sh in local runs. This
causes mkstemp() to fail with ENOENT. mkstemp() is replaced with
memfd_create() as it gives a shmem-backed file with no mount
needed while still reaching vfs_fallocate.
Changes in v2:
- Added patch 1 converting CHECK() to ASSERT_*() (Andrii)
- Link to v1: https://lore.kernel.org/bpf/20261102-d-path-memfd-v1-1-692a5664b36d@gmail.com/
