Subject: smbd: use openat_pathref_fsp() in reply_search()
X-Git-Tag: samba-4.14.0rc1~347
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=14b0cc6b9a1027b4d6d95be58d05f72e375d9f56;p=thirdparty%2Fsamba.git

smbd: use openat_pathref_fsp() in reply_search()

Ensures we have a pathref handle in the smb_fname we pass to
SMB_VFS_CREATE_FILE().

As the create_disposition is FILE_OPEN we just return the error if
openat_pathref_fsp() fails
