From: Alban Crequy Date: Mon, 4 Oct 2010 08:48:28 +0000 (+0000) Subject: AF_UNIX: Implement SO_TIMESTAMP and SO_TIMETAMPNS on Unix sockets X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f66116e89521ef71ab0d63dc07a639def88a577;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git AF_UNIX: Implement SO_TIMESTAMP and SO_TIMETAMPNS on Unix sockets Userspace applications can already request to receive timestamps with: setsockopt(sockfd, SOL_SOCKET, SO_TIMESTAMP, ...) Although setsockopt() returns zero (success), timestamps are not added to the ancillary data. This patch fixes that on SOCK_DGRAM and SOCK_SEQPACKET Unix sockets.
