This is incorrect for case-insensitive filesystems\nand ext4 directories with casefold enabled.\n\nQuery the underlying filesystem's actual case sensitivity via\nnfsd_get_case_info() and return accurate values to clients. This\nsupports per-directory settings for filesystems that allow mixing\ncase-sensitive and case-insensitive directories within an export.\n\nThe helper queries the parent dentry for non-directory filehandles\nbecause case-folding is a per-directory property. That resolution\nhas the same corner cases here as for NFSv3 PATHCONF: single-file\nexports query an unexported parent, disconnected dentries report\ndefaults until reconnected, and hardlinked files track whichever\nalias the dcache currently holds.\n\nReviewed-by: Roland Mainz <roland.mainz@nrubsig.org>\nSigned-off-by: Chuck Lever <chuck.lever@oracle.com>\n---\n fs/nfsd/nfs4xdr.c | 52 +++++++++++++++++++++++++++++++++++++++++++++++++---\n 1 file changed, 49 insertions(+), 3 deletions(-)", "diff": "diff --git a/fs/nfsd/nfs4xdr.c b/fs/nfsd/nfs4xdr.c\nindex 2a0946c630e1..d77304692e11 100644\n--- a/fs/nfsd/nfs4xdr.c\n+++ b/fs/nfsd/nfs4xdr.c\n@@ -3158,6 +3158,8 @@ struct nfsd4_fattr_args {\n \tu32\t\t\trdattr_err;\n \tbool\t\t\tcontextsupport;\n \tbool\t\t\tignore_crossmnt;\n+\tbool\t\t\tcase_insensitive;\n+\tbool\t\t\tcase_preserving;\n };\n \n typedef __be32(*nfsd4_enc_attr)(struct xdr_stream *xdr,\n@@ -3356,6 +3358,33 @@ static __be32 nfsd4_encode_fattr4_acl(struct xdr_stream *xdr,\n \treturn nfs_ok;\n }\n \n+static __be32 nfsd4_encode_fattr4_case_insensitive(struct xdr_stream *xdr,\n+\t\t\t\t\tconst struct nfsd4_fattr_args *args)\n+{\n+\treturn nfsd4_encode_bool(xdr, args->case_insensitive);\n+}\n+\n+static __be32 nfsd4_encode_fattr4_case_preserving(struct xdr_stream *xdr,\n+\t\t\t\t\tconst struct nfsd4_fattr_args *args)\n+{\n+\treturn nfsd4_encode_bool(xdr, args->case_preserving);\n+}\n+\n+static __be32 nfsd4_encode_fattr4_homogeneous(struct xdr_stream *xdr,\n+\t\t\t\t\tconst struct nfsd4_fattr_args *args)\n+{\n+\t/*\n+\t * Casefold-capable filesystems (e.g. ext4 or f2fs with the\n+\t * casefold feature) attach a Unicode encoding at mount time\n+\t * but apply case folding per directory.
