Those have been very useful in flushing out nfs export bugs in the past and they have also flushed out a few bugs from the RFC patch I sent yesterday. Thanks, Amir. Changes since RFC: - Fix bug in ovl_verify_index() - Open code ovl_dentry_to_fh() [Al] - Zero buffer in ovl_encode_real_fh() [Al] - Support decoding old (misaligned) file handles from the wire [Al] - Add patch to simplify memory allocation in ovl_encode_real_fh() [Al] Amir Goldstein (2): ovl: make sure that real fid is 32bit aligned in memory ovl: don't use a temp buf for encoding real fh fs/overlayfs/copy_up.c | 53 +++++++++++++------------- fs/overlayfs/export.c | 80 ++++++++++++++++++++++++---------------- fs/overlayfs/namei.c | 44 +++++++++++----------- fs/overlayfs/overlayfs.h | 34 ++++++++++++++--- 4 files changed, 124 insertions(+), 87 deletions(-) -- 2.17.1
