60dbcce1567f6502215b36ba4066e8fd1f86d706 - selftests/fuse: test post-EOF page zeroing when a file is extended

Fri, 31 Jul 2026 22:38:42 +0200

selftests/fuse: test post-EOF page zeroing when a file is extendedAdd a regression test for the bug where extending a file left the tail ofthe old partial EOF page exposing stale mmap-dirtied data instead of zeros.The test is a self-contained raw /dev/fuse server (no libfuse dependency)that runs without writeback_cache and returns FOPEN_KEEP_CACHE, theconfiguration in which the bug is visible. Its backing data is always zeroin the hole, so any non-zero byte a read sees is stale page-cache data.All offsets are relative to the runtime page size. Four cases: - write_extend: pollute the post-EOF tail, extend past it by writing into a later page, and verify the tail reads back as zero; - ftruncate_extend: same, but extend via ftruncate(); - fallocate_extend: same, but extend via fallocate() at the old EOF; - extend_into_eof_page_preserves_data: an extending write landing inside the old EOF page must not be clobbered by the zeroing.Each case fails without the fix and passes with it.Signed-off-by: Jimmy Zuber Signed-off-by: Miklos Szeredi List of files: /linux/tools/testing/selftests/filesystems/fuse/write_extend_eof_test.c
