From 89caa2d17785a63f30c297067e0e136a1a56c5cb Mon Sep 17 00:00:00 2001 From: Ralph Boehme Date: Fri, 17 Feb 2017 08:10:53 +0100 Subject: [PATCH] vfs_streams_xattr: use fsp, not base_fsp The base_fsp's fd is always -1 as it's closed after being openend in create_file_unixpath(). Additionally in streams_xattr_open force using of SMB_VFS_FSETXATTR() by sticking the just created fd into the fsp (and removing it afterwards). --- source3/modules/vfs_streams_xattr.c | 41 +++++++++++++++---------------------- 1 file changed, 17 insertions(+), 24 deletions(-) diff --git a/source3/modules/vfs_streams_xattr.c b/source3/modules/vfs_streams_xattr.c index 5a484fa..6692636 100644 --- a/source3/modules/vfs_streams_xattr.c +++ b/source3/modules/vfs_streams_xattr.c @@ -264,7 +264,7 @@ static int streams_xattr_fstat(vfs_handle_struct *handle, files_struct *fsp, return -1; } - sbuf->st_ex_size = get_xattr_size(handle->conn, fsp->base_fsp, + sbuf->st_ex_size = get_xattr_size(handle->conn, fsp, io->base, io->xattr_name); if (sbuf->st_ex_size == -1) { return -1; @@ -399,6 +399,7 @@ static int streams_xattr_open(vfs_handle_struct *handle, char *xattr_name = NULL; int baseflags; int hostfd = -1; + int ret; DEBUG(10, ("streams_xattr_open called for %s with flags 0x%x\n", smb_fname_str_dbg(smb_fname), flags)); @@ -410,7 +411,6 @@ static int streams_xattr_open(vfs_handle_struct *handle, /* If the default stream is requested, just open the base file. */ if (is_ntfs_default_stream_smb_fname(smb_fname)) { char *tmp_stream_name; - int ret; tmp_stream_name = smb_fname->stream_name; smb_fname->stream_name = NULL; @@ -500,20 +500,13 @@ static int streams_xattr_open(vfs_handle_struct *handle, DEBUG(10, ("creating or truncating attribute %s on file %s\n", xattr_name, smb_fname->base_name)); - if (fsp->base_fsp->fh->fd != -1) { - if (SMB_VFS_FSETXATTR( - fsp->base_fsp, xattr_name, + fsp->fh->fd = hostfd; + ret = SMB_VFS_FSETXATTR(fsp, xattr_name, &null, sizeof(null), - flags & O_EXCL ?
