2019-11-04	fix failure to build time32 compat shims with out-of-tree builds	Rich Felker	1	-1/+1
	commit de90f38e3b105802655d19d965d66335d25d59ef omitted $(srcdir) from the makefile include pathname it added. since the include directive was prefixed with - to make it optional (for archs that don't use it), the failure to find arch/$(ARCH)/arch.mak was silent.
2019-11-03	fix time64 link regression of dlsym stub for static-linked programs	Rich Felker	1	-0/+4
	in commit 22daaea39f1cc5f7391f0a5cd84576ffb58c2860, the __dlsym_redir_time64 function providing the backend for __dlsym_time64 was defined only in the dynamic linker, and thus was undefined when static linking a program referencing dlsym. use the same stub_dlsym definition that provides __dlsym (the non-redirecting backend) for static linked programs to provide it, conditional on _REDIR_TIME64.
2019-11-02	move time_t and suseconds_t definitions to common alltypes.h.in	Rich Felker	17	-48/+2
	now that all 32-bit archs have 64-bit time_t (and suseconds_t), the arch-provided _Int64 macro (long or long long, as appropriate) can be used to define them, and arch-specific definitions are no longer needed.
2019-11-02	move time64 ioctl numbers to generic bits/ioctl.h	Rich Felker	6	-21/+5
	now that all 32-bit archs have 64-bit time types, the values for the time-related ioctls can be shared. the mechanism for this is an arch/generic version of the bits header. archs which don't use the generic header still need to duplicate the definitions. x32, which does not use the new time64 values of the macros, already has its own overrides, so this commit does not affect it.
2019-11-02	move time64 socket options from arch bits to top-level sys/socket.h	Rich Felker	10	-45/+11
	now that all 32-bit archs have 64-bit time types, the values for the time-related socket option macros can be treated as universal for 32-bit archs. the sys/socket.h mechanism for this predates arch/generic and is instead in the top-level header. x32, which does not use the new time64 values of the macros, already has its own overrides, so this commit does not affect it.
2019-11-02	switch all existing 32-bit archs to 64-bit time_t	Rich Felker	85	-217/+420
	this commit preserves ABI fully for existing interface boundaries between libc and libc consumers (applications or libraries), by retaining existing symbol names for the legacy 32-bit interfaces and redirecting sources compiled against the new headers to alternate symbol names. this does not necessarily, however, preserve the pairwise ABI of libc consumers with one another; where they use time_t-derived types in their interfaces with one another, it may be necessary to synchronize updates with each other. the intent is that ABI resulting from this commit already be stable and permanent, but it will not be officially so until a release is made. changes to some header-defined types that do not play any role in the ABI between libc and its consumers may still be subject to change. mechanically, the changes made by this commit for each 32-bit arch are as follows: - _REDIR_TIME64 is defined to activate the symbol redirections in public headers - COMPAT_SRC_DIRS is defined in arch.mak to activate build of ABI compat shims to serve as definitions for the original symbol names - time_t and suseconds_t definitions are changed to long long (64-bit) - IPC_STAT definition is changed to add the IPC_TIME64 bit (0x100), triggering conversion of semid_ds, shmid_ds, and msqid_ds split low/high time bits into new time_t members - structs semid_ds, shmid_ds, msqid_ds, and stat are modified to add new 64-bit time_t/timespec members at the end, maintaining existing layout of other members. - socket options (SO_*) and ioctl (sockios) command macros are redefined to use the kernel's "_NEW" values. in addition, on archs where vdso clock_gettime is used, the VDSO_CGT_SYM macro definition in syscall_arch.h is changed to use a new time64 vdso function if available, and a new VDSO_CGT32_SYM macro is added for use as fallback on kernels lacking time64.
