Subject: smbd: Open file as REPARSE_POINT in rename_internals()
X-Git-Tag: talloc-2.4.2~942
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=93f0a3671256d7bb66c64e31607660611e83af59;p=thirdparty%2Fsamba.git

smbd: Open file as REPARSE_POINT in rename_internals()

In the future we'll block opening symlinks as such in
SMB_VFS_CREATE_FILE() unless we open as reparse points.
