2019-08-05Add CLONE_PIDFD from Linux 5.2 to bits/sched.h.Joseph Myers
This patch adds the CLONE_PIDFD constant from Linux 5.2 to glibc's bits/sched.h. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/sched.h [__USE_GNU] (CLONE_PIDFD): New macro.

2019-07-24Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]Florian Weimer
The kernel changes for a 64-bit time_t on 32-bit architectures resulted in <asm/socket.h> indirectly including <linux/posix_types.h>. The latter is not namespace-clean for the POSIX version of <sys/socket.h>. This issue has persisted across several Linux releases, so this commit creates our own copy of the SO_* definitions for !__USE_MISC mode. The new test socket/tst-socket-consts ensures that the copy is consistent with the kernel definitions (which vary across architectures). The test is tricky to get right because CPPFLAGS includes include/libc-symbols.h, which in turn defines _GNU_SOURCE unconditionally. Tested with build-many-glibcs.py. I verified that a discrepancy in the definitions actually results in a failure of the socket/tst-socket-consts test.
2019-06-14Linux: Fix __glibc_has_include use for <sys/stat.h> and statxFlorian Weimer
The identifier linux is used as a predefined macro, so the actually used path is 1/stat.h or 1/stat64.h. Using the quote-based version triggers a file lookup for /usr/include/bits/linux/stat.h (or whatever directory is used to store bits/statx.h), but since bits/ is pretty much reserved by glibc, this appears to be acceptable. This is related to GCC PR 80005: incorrect macro expansion of the argument of __has_include. Suggested by Zack Weinberg. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2019-06-13Add IPV6_ROUTER_ALERT_ISOLATE from Linux 5.1 to bits/in.h.Joseph Myers

2019-06-12<sys/stat.h>: Use Linux UAPI header for statx if available and usefulFlorian Weimer
This will automatically import new STATX_* constants. It also avoids a conflict between <sys/stat.h> and <linux/stat.h>.
2019-06-07Linux: Add getdents64 system callFlorian Weimer
No 32-bit system call wrapper is added because the interface is problematic because it cannot deal with 64-bit inode numbers and 64-bit directory hashes. A future commit will deprecate the undocumented getdirentries and getdirentries64 functions. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
2019-05-23Add F_SEAL_FUTURE_WRITE from Linux 5.1 to bits/fcntl-linux.h.Joseph Myers

2019-05-14Linux: Add the tgkill functionFlorian Weimer
The tgkill function is sometimes used in crash handlers. <bits/signal_ext.h> follows the same approach as <bits/unistd_ext.h> (which was added for the gettid system call wrapper). Reviewed-by: Carlos O'Donell <carlos@redhat.com>

2018-10-24 Y2038: provide size of default time_t for target architectureAlbert ARIBAUD (3ADEV)
To determine whether the default time_t interfaces are 32-bit and so need conversions, or are 64-bit and so are compatible with the internal 64-bit type without conversions, a macro giving the size of the default time_t is also required. This macro is called __TIMESIZE. This macro can then be used instead of __WORDSIZE in msq-pad.h and shm-pad.h files, which in turn allows removing their x86 variants, and in sem-pad.h files but keeping the x86 variant.

2018-10-17Use single bits/shm.h for all architectures.Joseph Myers
After my patch to move SHMLBA to its own header, the bits/shm.h headers for architectures using the Linux kernel still vary in a few ways: the use of __syscall_ulong_t; whether padding for 32-bit systems is present before or after time fields, or missing altogether (mips, x32); whether shm_segsz is before or after the time fields; whether, if after time fields, there is extra padding before shm_segsz. This patch arranges for a single header to be used. __syscall_ulong_t is safe to use everywhere, while bits/shm-pad.h is added with new macros __SHM_PAD_AFTER_TIME, __SHM_PAD_BEFORE_TIME, __SHM_SEGSZ_AFTER_TIME and __SHM_PAD_BETWEEN_TIME_AND_SEGSZ to describe the differences.

2018-10-17Move SHMLBA to its own header.Joseph Myers
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).

2018-10-15Use single bits/sem.h for all architectures.Joseph Myers
The bits/sem.h headers for architectures using the Linux kernel vary in a few ways: * x32 uses __syscall_ulong_t instead of unsigned long int. * The x86 header uses padding after time fields unconditionally (including for both x86_64 ABIs), not just for 32-bit time (unlike in msqid_ds where there is only padding for 32-bit time). Because this padding is present for x32, and is __syscall_ulong_t there, it does have to be __syscall_ulong_t, not unsigned long int. * The MIPS header never uses padding around time fields, even when 32-bit (unlike in msqid_ds where it has endian-dependent padding for 32-bit time). * Some older 32-bit big-endian architectures have padding before rather than after time fields, although the preferred generic approach is padding after the time fields independent of endianness. (There are also insubstantial differences such as use of unsigned int for padding instead of unsigned long int, which makes no difference to layout since the padding fields using unsigned int are only present on 32-bit architectures.) For the first, __syscall_ulong_t can be used in the generic version as it's the same as unsigned long int everywhere except x32. For the other differences, this patch adds macros __SEM_PAD_BEFORE_TIME and __SEM_PAD_AFTER_TIME in a new bits/sem-pad.h header, so that header is the only one needing to be provided on architectures with differences in this area, and everything else can go in a single common bits/sem.h header.

2018-10-11Use single bits/msq.h for all architectures.Joseph Myers
The bits/msq.h headers for architectures using the Linux kernel vary in a few ways: * x32 uses __syscall_ulong_t instead of unsigned long int. * x32 has 64-bit time_t, so no padding around time fields despite __WORDSIZE == 32. * Some older 32-bit big-endian architectures have padding before rather than after time fields, although the preferred generic approach is padding after the time fields independent of endianness. (There are also insubstantial differences such as use of unsigned int for padding instead of unsigned long int, which makes no difference to layout since the padding fields using unsigned int are only present on 32-bit architectures.) For the first, __syscall_ulong_t can be used in the generic version as it's the same as unsigned long int everywhere except x32. For the other two differences, this patch adds macros __MSQ_PAD_BEFORE_TIME and __MSQ_PAD_AFTER_TIME in a new bits/msq-pad.h header, so that header is the only one needing to be provided on architectures with differences in this area, and everything else can go in a single common bits/msq.h header. Once we have __TIMESIZE, the generic bits/msq-pad.h can change to use that instead of __WORDSIZE, at which point the x86 version of bits/msq-pad.h won't be needed either. Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Add bits/msq-pad.h. * sysdeps/unix/sysv/linux/bits/msq.h: Include <bits/msq-pad.h> instead of <bits/wordsize.h>.

2018-10-10Use common bits/shm.h for more architectures.Joseph Myers
sysdeps/unix/sysv/linux/bits/shm.h has padding after time fields in struct shmid_ds unconditionally, and thus is only suitable for 32-bit architectures (no 64-bit configurations use this file); sysdeps/unix/sysv/linux/generic/bits/shm.h is substantively the same, except that the padding is conditioned on __WORDSIZE == 32, and so it can be used for 64-bit architectures as well. This patch adds the conditionals to sysdeps/unix/sysv/linux/bits/shm.h. The linux/generic/ version is then no longer needed and so is removed, as are the alpha and s390 versions which are also no longer needed. The other architecture-specific versions have different padding, layout, types or SHMLBA definitions and so are still needed after this change. This is essentially the same change for bits/shm.h as the bits/msq.h patch and the bits/sem.h patch. However, the details of the padding variations for the architectures that aren't changed are not all the same between msqid_ds, shmid_ds and semid_ds.

2018-09-26Share MAP_* flags between more architectures.Joseph Myers
Continuing bits/mman.h unification between architectures using the Linux kernel, this patch arranges for the common set of MAP_* flags to be used by two more architectures. That common set is moved to bits/mman-map-flags-generic.h, which is included by bits/mman.h, to allow architectures to use that common set even if they also have architecture-specific additions to it. As well as the generic bits/mman.h, the versions for x86 and ia64 are also then made to include bits/mman-map-flags-generic.h, so while they still need architecture-specific bits/mman.h (for MAP_32BIT and MAP_GROWSUP respectively), they do not need to duplicate the generic flag definitions in there.

2018-09-25Complete sys/procfs.h unification.Joseph Myers
This patch completes the process of unifying sys/procfs.h headers for architectures using the Linux kernel by making alpha use the generic version. That was previously deferred because alpha has different definitions of prgregset_t and prfpregset_t from other architectures, so changing to the common definitions would change C++ name mangling. To avoid such a change, a header bits/procfs-prregset.h is added, and alpha gets its own version of that header.

2018-09-25Unify more sys/procfs.h headers.Joseph Myers
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>.

2018-09-25Unify some sys/procfs.h headers.Joseph Myers
As per recent discussions, this patch unifies some of the sys/procfs.h headers for architectures using the Linux kernel, producing a generic version that can hopefully be used by all new architectures as well. The new generic version is based on the AArch64 one. The register definitions, the only part that generally needs to vary by architecture, go in a new bits/procfs.h header (which each architecture using the generic version needs to provide); that header also has any #includes that were in the architecture-specific sys/procfs.h, where those includes went beyond the generic set. The generic version is used for eight architectures where the generic definitions were the same as the architecture-specific ones. (Some of those architectures had #if 0 fields, now removed; some defined types or fields using different type names which were typedefs for the same underlying types.) Six of the remaining architectures with their own sys/procfs.h use unsigned short for pr_uid / pr_gid in some cases; moving those to the generic header will require a bits/ header to define a typedef for the type of those fields. In the case of alpha, the generic sys/procfs.h uses elf_gregset_t (= unsigned long int[33]) to define prgregset_t and elf_fpregset_t (= double[32]) to define prfpregset_t, but the alpha version uses gregset_t (= long int[33]) and fpregset_t (= long int[32]), so avoiding unnecessarily changing the underlying types (and thus C++ name mangling) again means a bits/ header will need to be able to define a different choice for those typedefs. bits/procfs.h is included outside the __BEGIN_DECLS / __END_DECLS pair (whereas the definitions it contains were previously inside that pair in various sys/procfs.h headers), because it sometimes includes other headers and putting those other #includes inside that pair seems risky. Because none of the declarations in bits/procfs.h are of functions or variables or involve function types, I don't think it makes any difference whether they are inside or outside an extern "C" context.

2018-09-18Unify many bits/mman.h headers.Joseph Myers
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). Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/bits/mman.h: New file. * sysdeps/unix/sysv/linux/aarch64/bits/mman.h: Remove. * sysdeps/unix/sysv/linux/arm/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/nios2/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/mman.h: Likewise.
2018-09-17Update siginfo constants from Linux kernel (bug 21286).Joseph Myers
As of Linux 4.17, siginfo headers in the Linux kernel have been largely unified across architectures (so various constants are defined with common values in include/uapi/asm-generic/siginfo.h even if not all architectures can generate those particular constants). This patch makes glibc reflect that unification and the current set of constants in that header as of Linux 4.18. Various constants are added to bits/siginfo-consts.h (under the same feature test macro conditions as the other constants with the same prefix), and removed from the ia64 bits/siginfo-consts-arch.h where they were previously there - this is not limited to constants added by the unification. Nothing is done about macros that are defined in include/uapi/asm-generic/siginfo.h with names with leading '__' (some of those are ia64-specific ones that remain in the ia64 bits/siginfo-consts-arch.h without the leading '__' there). A consequence of these changes is that TRAP_HWBKPT becomes available on AArch64 and all other architectures as requested in bug 21286. Tested for x86_64; tested with build-many-glibcs.py for ia64.
