Adhemerval Zanella 948ce73b31 Linux: Only generate 64 bit timestamps for 64 bit time_t recvmsg/recvmmsg ... The timestamps created by __convert_scm_timestamps only make sense for 64 bit time_t programs, 32 bit time_t programs will ignore 64 bit time_t timestamps since SO_TIMESTAMP will be defined to old values (either by glibc or kernel headers). Worse, if the buffer is not suffice MSG_CTRUNC is set to indicate it (which breaks some programs [1]). This patch makes only 64 bit time_t recvmsg and recvmmsg to call __convert_scm_timestamps. Also, the assumption to called it is changed from __ASSUME_TIME64_SYSCALLS to __TIMESIZE != 64 since the setsockopt might be called by libraries built without __TIME_BITS=64. The MSG_CTRUNC is only set for the 64 bit symbols, it should happen only if 64 bit time_t programs run older kernels. Checked on x86_64-linux-gnu and i686-linux-gnu.
