Subject: [PATCH 2/3] socket: Rename SO_RCVTIMEO/ SO_SNDTIMEO with _OLD suffixes
Date: Mon, 7 Jan 2019 21:22:54 -0800 [thread overview]
Message-ID: <20190108052255.10699-3-deepa.kernel@gmail.com> (raw)
In-Reply-To: <20190108052255.10699-1-deepa.kernel@gmail.com>
SO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval
as the time format. struct timeval is not y2038 safe.
The subsequent patches in the series add support for new socket
timeout options with _NEW suffix that are y2038 safe.
Rename the existing options with _OLD suffix forms so that the
right option is enabled for userspace applications according
to the architecture and time_t definition of libc.
