Subject: s3:libsmb: normalize leading slashes in cli_resolve_path()
X-Git-Tag: tevent-0.9.32~20
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=07eb10b7457adc9a994284d7e7ea12bbb3f5d2f5;p=thirdparty%2Fsamba.git

s3:libsmb: normalize leading slashes in cli_resolve_path()

As we try to pass the path to an SMB2 server, we should have
just one leading backslash (which then gets ignored in
cli_smb2_create_fnum_send()).
