After commit 5c1768b67250 ("f2fs: fix to do sanity check correctly on

correctly, let's add this regression testcase to check that.Cc: Jaegeuk Kim <[email protected]> Signed-off-by: Chao Yu <[email protected]> --- tests/f2fs/023 | 44 ++++++++++++++++++++++++++++++++++++++++++++ tests/f2fs/023.out | 2 ++ 2 files changed, 46 insertions(+) create mode 100755 tests/f2fs/023 create mode 100644 tests/f2fs/023.out diff --git a/tests/f2fs/023 b/tests/f2fs/023 new file mode 100755 index 00000000..d1b7df32 --- /dev/null +++ b/tests/f2fs/023 @@ -0,0 +1,44 @@ +#! /bin/bash +# SPDX-License-Identifier: GPL-2.0 +# Copyright (c) 2025 Chao Yu <[email protected]> +# +# FS QA Test No. f2fs/023 +# +# This testcase tries to inject fault into inode.i_inline_xattr_size, +# and check whether sanity check of f2fs can handle fault correctly. +# + +. ./common/preamble +_begin_fstest auto quick rw + +_fixed_by_kernel_commit 5c1768b67250 \ + "f2fs: fix to do sanity check correctly on i_inline_xattr_size" + +_require_scratch_nocheck +_require_inject_f2fs_command node i_inline +_require_inject_f2fs_command node i_inline_xattr_size + +testfile=$SCRATCH_MNT/testfile + +# remove all mkfs options to avoid layout change of on-disk inode +export MKFS_OPTIONS="" + +_scratch_mkfs "-O extra_attr,flexible_inline_xattr" >> $seqres.full +_scratch_mount "-o inline_xattr_size=512" >>$seqres.full 2>&1 +touch $testfile +_scratch_unmount + +# inject .i_inline field: clear F2FS_EXTRA_ATTR bit +$F2FS_INJECT_PROG --node --mb i_inline --nid 4 --val 0x1 $SCRATCH_DEV \ + >>$seqres.full || _fail "failed to inject i_inline" + +# inject .i_inline_xattr_size field from 512 to 2048 +$F2FS_INJECT_PROG --node --mb i_inline_xattr_size --nid 4 --val 2048 $SCRATCH_DEV \ + >>$seqres.full || _fail "failed to inject i_inline_xattr_size" + +_scratch_mount + +getfattr -n user.test "$testfile" 2>&1 | awk -F ': ' '/Structure needs cleaning/ { print $NF }' + +status=0 +exit diff --git a/tests/f2fs/023.out b/tests/f2fs/023.out new file mode 100644 index 00000000..7f16f33f --- /dev/null +++ b/tests/f2fs/023.out @@ -0,0 +1,2 @@ +QA output created by 023 +Structure needs cleaning -- 2.49.0 _______________________________________________ Linux-f2fs-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/linux-f2fs-devel
