* Always define __USE_TIME_BITS64 when 64 bit time_t is usedAdhemerval Zanella2024-04-021-4/+4
| | | | | | | | | | | | | | | | | | | | It was raised on libc-help [1] that some Linux kernel interfaces expect the libc to define __USE_TIME_BITS64 to indicate the time_t size for the kABI. Different than defined by the initial y2038 design document [2], the __USE_TIME_BITS64 is only defined for ABIs that support more than one time_t size (by defining the _TIME_BITS for each module). The 64 bit time_t redirects are now enabled using a different internal define (__USE_TIME64_REDIRECTS). There is no expected change in semantic or code generation. Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, and arm-linux-gnueabi [1] https://sourceware.org/pipermail/libc-help/2024-January/006557.html [2] https://sourceware.org/glibc/wiki/Y2038ProofnessDesign Reviewed-by: DJ Delorie <dj@redhat.com>

* Linux: Consolidate typesizes.hAdhemerval Zanella Netto2022-12-071-0/+74
| | | | | | | | | | | | | | | The generic (sysdeps/unix/sysv/linux/generic/bits/typesizes.h) and default (bits/typesizes.h) differs in two fields: bits/typesizes.h Linux generic __NLINK_T_TYPE __UWORD_TYPE __U32_TYPE __BLKSIZE_T_TYPE __SLONGWORD_TYPE __S32_TYPE Sinceit leads to different C++ mangling names, the default typesize.h is copied for the requires archtiectures and the generic is make the default Linux one.

* linux: Fix generic struct_stat for 64 bit time (BZ# 29657)Adhemerval Zanella2022-10-251-0/+139
| | | | | | | | | | | | | | | | | The generic Linux struct_stat misses the conditionals to use bits/struct_stat_time64_helper.h in the __USE_TIME_BITS64 for architecture that uses __TIMESIZE == 32 (currently csky and nios2). Since newer ports should not support 32 bit time_t, the generic implementation should be used as default. For arm, hppa, and sh a copy of default struct_stat is added, while for csky and nios a new one based on generic is used, along with conditionals to use bits/struct_stat_time64_helper.h. The default struct_stat is also replaced with the generic one. Checked on aarch64-linux-gnu and arm-linux-gnueabihf.

* Move SHMLBA to its own header.Joseph Myers2018-10-172-102/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One difference between bits/shm.h headers for architectures using the Linux kernel is the definition of SHMLBA. This was noted in <https://sourceware.org/ml/libc-alpha/2018-09/msg00175.html> as a reason why even a new architecture (C-SKY) might need its own bits/shm.h; thus, splitting it out of bits/shm.h can allow less duplication of headers for new architectures. This patch moves that definition to its own header, bits/shmlba.h, to allow more sharing of headers between architectures. That move allows the arm, ia64 and sh variants of bits/shm.h to be removed, as they had no other significant differences from the generic bits/shm.h; powerpc and x86 have their own bits/shm.h but do not need to get their own bits/shmlba.h because they use the same SHMLBA as the generic header. Other architectures with their own bits/shm.h get their own bits/shmlba.h without being able to remove their own bits/shm.h until the generic one has been adapted to be able to handle more architectures (where, in addition to the differences seen for bits/msq.h and bits/sem.h, the position of shm_segsz in struct shmid_ds also depends on the architecture).

* Unify more sys/procfs.h headers.Joseph Myers2018-09-252-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues the process of unifying sys/procfs.h headers for architectures using the Linux kernel. A bits/procfs-id.h header is added to define __pr_uid_t and __pr_gid_t for the types of pr_uid and pr_gid; the default version of this header uses unsigned int. On some architectures, sys/procfs.h has copies of 32-bit structures for 64-bit builds; those move into a bits/procfs-extra.h header (they can't go in bits/procfs.h because they have to come *after* other declarations from sys/procfs.h). Given appropriate versions of these headers, six more architectures can then move to providing only bits/procfs*.h without duplicating the rest of the contents of sys/procfs.h. Only alpha needs a further bits/ header to be added before it can stop having its own sys/procfs.h. Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/sys/procfs.h: Include <bits/procfs-id.h> and <bits/procfs-extra.h>.

* Unify many bits/mman.h headers.Joseph Myers2018-09-181-44/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many bits/mman.h headers for Linux architectures have exactly the same contents, up to whitespace, comments and the number of leading 0s on constants. Specifically, this applies to architectures that, in the Linux kernel, either have no uapi/asm/mman.h, or have one that includes asm-generic/mman.h without any changes or additions relevant to glibc (this last case is the one that applies to Arm). It's not useful to have to duplicate the set of MAP_* constants in glibc for all such architectures and any new architectures with that property. Thus, this patch creates a generic sysdeps/unix/sysv/linux/bits/mman.h and removes all the architecture-specific versions that become unnecessary. Further unification remains possible after this patch. For example, the new bits/mman.h could become bits/mman-map-flags-generic.h so that it could also be used by architecture-specific bits/mman.h headers on architectures that use the generic flags but add architecture-specific ones to them. That would allow this common set of MAP_* definitions to be used on ia64 and x86 as well (architectures that include asm-generic/mman.h from their own uapi/asm/mman.h but define additional MAP_* values of their own).

* Add arch-specific configuration for C11 atomics support.Torvald Riegel2014-11-201-0/+3
| | | | | | | | This sets __HAVE_64B_ATOMICS if provided. It also sets USE_ATOMIC_COMPILER_BUILTINS to true if the existing atomic ops use the __atomic* builtins (aarch64, mips partially) or if this has been tested (x86_64); otherwise, this is set to false so that C11 atomics will be based on the existing atomic operations.

| | | | | | | | As reported in http://bugzilla.redhat.com/533063 , preadv/pwritev prototypes are wrong on 32-bit arches with -D_FILE_OFFSET_BITS=64 and as I've just found, fallocate is wrong too. The problem is that only off_t is remapped to the 64-bit type transparently, __off_t is not.
