* linux: Only use 64-bit syscall if required for sigtimedwaitAdhemerval Zanella2021-06-223-9/+36
| | | | | | | | | | | For !__ASSUME_TIME64_SYSCALLS there is no need to issue a 64-bit syscall if the provided timeout fits in a 32-bit one.

The 64 bit time support is only enabled if LFS (_FILE_OFFSET_BITS=64) is also used. Different than LFS support, the y2038 symbols are added only for the required ABIs (armhf, csky, hppa, i386, m68k, microblaze, mips32, mips64-n32, nios2, powerpc32, sparc32, s390-32, and sh). The ABIs with 64-bit time support are unchanged, both for symbol and types redirection. On Linux the full 64-bit time support requires a minimum of kernel version v5.1. Otherwise, the 32-bit fallbacks are used and might results in error with overflow return code (EOVERFLOW). The i686-gnu does not yet support 64-bit time.

| | | | | | | | | | | | | Instead of replicate the same definitions from struct_stat_time64.h on the multiple struct_stat.h, use a common header which is included when required (struct_stat_time64_helper.h). The 64-bit time support is added only for LFS support. The __USE_TIME_BITS64 is not defined internally yet, although the internal header is used when building the 64-bit stat implementations.

* linux: Add recvvmsg fallback for 64-bit time_t SO_TIMESTAMP{NS}Adhemerval Zanella2021-06-151-2/+15
| | | | | | | | | | | | | | | | | | | | | | Handle the SO_TIMESTAMP{NS} similar to recvmsg: for !__ASSUME_TIME64_SYSCALLS it converts the first 32-bit time SO_TIMESTAMP or SO_TIMESTAMPNS and appends it to the control buffer if has extra space or returns MSG_CTRUNC otherwise. The 32-bit time field is kept as-is. Also for !__ASSUME_TIME64_SYSCALLS it limits the maximum number of 'struct mmsghdr *' to IOV_MAX (and also increases the stack size requirement to IOV_MAX times sizeof (socklen_t)). The Linux imposes a similar limit to sendmmsg, so bound the array size on recvmmsg is not unreasonable. And this will be used only on older when building with 32-bit time support. Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15 kernel).

| | | | | | | | | | | | | | | | | | | | | | The recvmsg handling is more complicated because it requires check the returned kernel control message and make some convertions. For !__ASSUME_TIME64_SYSCALLS it converts the first 32-bit time SO_TIMESTAMP or SO_TIMESTAMPNS and appends it to the control buffer if has extra space or returns MSG_CTRUNC otherwise. The 32-bit time field is kept as-is. Calls with __TIMESIZE=32 will see the converted 64-bit time control messages as spurious control message of unknown type. Calls with __TIMESIZE=64 running on pre-time64 kernels will see the original message as a spurious control ones of unknown typ while running on kernel with native 64-bit time support will only see the time64 version of the control message.

* linux: Add fallback for 64-bit time_t SO_{RCV,SND}TIMEOAdhemerval Zanella2021-06-147-15/+276
| | | | | | | | | | | | | | | | | | | The constant values will be changed for __TIMESIZE=64, so binaries built with 64-bit time support might fail to work properly on old kernels. Both {get,set}sockopt will retry the syscall with the old constant values and the timeout value adjusted when kernel returns ENOTPROTOPT. It also adds an internal only SO_{RCV,SND}TIMEO where COMPAT_SO_{RCV,SND}TIMEO_OLD indicates pre 32-bit time support and COMPAT_SO_{RCV,SND}TIMEO_NEW indicates time64 support. It allows to refer to constant independently of the time_t ABI and kernel version used. Checked on x86_64-linux-gnu and i686-linux-gnu (on 5.4 and on 4.15 kernel).
