- Authentication-results: sourceware.org; auth=none
This patch updates sysdeps/gnu/netinet/tcp.h to include new
definitions from include/uapi/linux/tcp.h in Linux 4.13.
Tested for x86_64.
2017-09-06 Joseph Myers <joseph@codesourcery.com>
* sysdeps/gnu/netinet/tcp.h (TCP_ULP): New macro.
(TCP_MD5SIG_EXT): Likewise.
(TCP_MD5SIG_FLAG_PREFIX): Likewise.
(struct tcp_md5sig): Replace __tcpm_pad1 by tcpm_flags and
tcpm_prefixlen. Rename __tcpm_pad2 to __tcpm_pad.
