2024-02-25Add support for using time64 on big-endian machines.Dmitry Chestnykh
For BE architectures there is one significant difference in comparison with time64 support for little-endian architectures like ARMv7. The difference is that we strictly need to pass two 64bit values to system calls because Linux Kernel internally uses `struct __kernel_timespec` and similar, which consists of two 64bit fields. For this reason many files have been changed to convert pointers to timespec-family structures (mixed of 64bit and 32bit values) to the pointer of the similar but 64bit-only structures for using as system calls args. This is general prerequisite for any BE architecture. Signed-off-by: Dmitry Chestnykh <dm.chestnykh@gmail.com>
2024-02-22Introduce time64 support.Dmitry Chestnykh
This patch introduces *time64 syscalls support for uClibc-ng. Currently the redirection of syscalls to their *time64 analogs is fully supported for 32bit ARM (ARMv5, ARMv6, ARMv7). The main changes that take effect when time64 feature is enabled are: - sizeof(time_t) is 8. - There is a possibility os setting date beyond year 2038. - some syscalls are redirected: clock_adjtime -> clock_adjtime64 clock_getres -> clock_getres_time64 clock_gettime -> clock_gettime64 clock_nanosleep -> clock_nanosleep_time64 clock_settime -> clock_settime64 futex -> futex_time64 mq_timedreceive -> mq_timedreceive_time64 mq_timedsend -> mq_timedsend_time64 ppoll -> ppoll_time64 pselect6 -> pselect6_time64 recvmmsg -> recvmmsg_time64 rt_sigtimedwait -> rt_sigtimedwait_time64 sched_rr_get_interval -> sched_rr_get_interval_time64 semtimedop -> semtimedop_time64 timer_gettime -> timer_gettime64 timer_settime -> timer_settime64 timerfd_gettime -> timerfd_gettime64 timerfd_settime -> timerfd_settime64 utimensat -> utimensat_time64. - settimeofday uses clock_settime (like in glibc/musl). - gettimeofday uses clock_gettime (like in glibc/musl). - nanosleep uses clock_nanosleep (like in glibc/musl). - There are some fixes in data structures used by libc and kernel for correct data handling both with and without enabled time64 support.

2017-10-01recvmmsg/sendmmsg: add recvmmsg sendmmsg support.Guo Ren
The recvmmsg and sendmmsg is very important for UDP stream application. If we only use recvmsg for UDP stream, it will only copy one mtu size of data in a syscall. And recvmmsg copy as many as you want in a syscall. So recvmmsg is more efficient,and some applications will depends on the recvmmsg and sendmmsg, eg: UDP media stream player.

2015-11-13i386: use socketcall even if newer linux exposes direct syscallsWaldemar Brodkorb
The changeset 9dea5dc921b5f4045a18c63eb92e84dc274d17eb in the Linux kernel expose the direct syscalls for sockets. For example udhcpc then will use sendto syscall directly and get an EINVAL error. Disable direct syscalls as it was done for SPARC in the past. Musl and GNU libc are not affected, as they already disable direct socket syscalls on i386.

2014-08-18unbreak networking code for sparcWaldemar Brodkorb
This commit 1e2e4ac6193ffe0900bd392fa3c596883771eb34 breaks networking on sparc systems. In Linux the socket functions are declared, but not implemented and must be routed through socketcall().
