* sysv: linux: Add 64-bit time_t variant for shmctlAdhemerval Zanella2020-07-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To provide a y2038 safe interface a new symbol __shmctl64 is added and __shmctl is change to call it instead (it adds some extra buffer copying for the 32 bit time_t implementation). Two new structures are added: 1. kernel_shmid64_ds: used internally only on 32-bit architectures to issue the syscall. A handful of architectures (hppa, i386, mips, powerpc32, and sparc32) require specific implementations due to their kernel ABI. 2. shmid_ds64: this is only for __TIMESIZE != 64 to use along with the 64-bit shmctl. It is different than the kernel struct because the exported 64-bit time_t might require different alignment depending on the architecture ABI. So the resulting implementation does: 1. For 64-bit architectures it assumes shmid_ds already contains 64-bit time_t fields and will result in just the __shmctl symbol using the __shmctl64 code. The shmid_ds argument is passed as-is to the syscall. 2. For 32-bit architectures with default 64-bit time_t (newer ABIs such riscv32 or arc), it will also result in only one exported symbol but with the required high/low time handling. 3. Finally for 32-bit architecture with both 32-bit and 64-bit time_t support we follow the already set way to provide one symbol with 64-bit time_t support and implement the 32-bit time_t support using of the 64-bit one. The default 32-bit symbol will allocate and copy the shmid_ds over multiple buffers, but this should be deprecated in favor of the __shmctl64 anyway. Checked on i686-linux-gnu and x86_64-linux-gnu. I also did some sniff tests on powerpc, powerpc64, mips, mips64, armhf, sparcv9, and sparc64.

* sysv: linux: Add 64-bit time_t variant for semctlAdhemerval Zanella2020-07-091-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Different than others 64-bit time_t syscalls, the SysIPC interface does not provide a new set of syscall for y2038 safeness. Instead it uses unused fields in semid_ds structure to return the high bits for the timestamps. To provide a y2038 safe interface a new symbol __semctl64 is added and __semctl is change to call it instead (it adds some extra buffer copying for the 32 bit time_t implementation). Two new structures are added: 1. kernel_semid64_ds: used internally only on 32-bit architectures to issue the syscall.

It is different than the kernel struct because the exported 64-bit time_t might require different alignment depending on the architecture ABI. So the resulting implementation does: 1. For 64-bit architectures it assumes semid_ds already contains 64-bit time_t fields and will result in just the __semctl symbol using the __semctl64 code.

For 32-bit architectures with default 64-bit time_t (newer ABIs such riscv32 or arc), it will also result in only one exported symbol but with the required high/low handling. It might be possible to optimize it further to avoid the kernel_semid64_ds to semun transformation if the exported ABI for the architectures matches the expected kernel ABI, but the implementation is already complex enough and don't think this should be a hotspot in any case. 3. Finally for 32-bit architecture with both 32-bit and 64-bit time_t support we follow the already set way to provide one symbol with 64-bit time_t support and implement the 32-bit time_t support using the 64-bit one.

* signal: Add signum-{generic,arch}.hAdhemerval Zanella2020-07-072-75/+69
| | | | | | | | | | | | | | | | | | | | It refactor how signals are defined by each architecture. Instead of include a generic header (bits/signum-generic.h) and undef non-default values in an arch specific header (bits/signum.h) the new scheme uses a common definition (bits/signum-generic.h) and each architectures add its specific definitions on a new header (bits/signum-arch.h). For Linux it requires copy some system default definitions to alpha, hppa, and sparc. They are historical values and newer ports uses the generic Linux signum-arch.h. For Hurd the BSD signum is removed and moved to a new header (it is used currently only on Hurd). Checked on a build against all affected ABIs.

* sysvipc: Set ipc_perm mode as mode_t (BZ#18231)Adhemerval Zanella2019-10-102-62/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sets the mode field in ipc_perm as mode_t for all architectures, as POSIX specification [1]. The changes required are as follow: 1. It moves the ipc_perm definition out of ipc.h to its own header ipc_perm.h. It also allows consolidate the IPC_* definition on only one header. 2. The generic implementation follow the kernel ipc64_perm size so the syscall can be made directly without temporary buffer copy. However, since glibc defines the MODE field as mode_t, it omits the __PAD1 field (since glibc does not export mode_t as 16-bit for any architecture). It is a two-fold improvement: 2.1. New implementation which follow Linux UAPI will not need to provide an arch-specific ipc-perm.h header neither wrongly use the wrong 16-bit definition from previous default ipc.h (as csky did). 2.1. It allows consolidate ipc_perm definition for architectures that already provide mode_t as 32-bit. 3. All kernel ABIs for the supported architectures already provides the expected padding for mode type extension to 32-bit. However, some architectures the padding has the wrong placement, so it requires the ipc control routines (msgctl, semctl, and shmctl) to adjust the mode field accordingly. Currently they are armeb, microblaze, m68k, s390, and sheb. A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the required ABIs define. 4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also require compat symbols that do not adjust the mode field. Checked on arm-linux-gnueabihf, aarch64-linux-gnu, powerpc64le-linux-gnu, and x86_64-linux-gnu. I also checked the sysvipc tests on hppa-linux-gnu, sh4-linux-gnu, s390x-linux-gnu, and s390-linux-gnu.

* Linux: Use in-tree copy of SO_ constants for !__USE_MISC [BZ #24532]Florian Weimer2019-07-241-0/+38
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. This patch was tested by running 'make check' on branch master then applying this patch and running 'make check' again, and checking that both 'make check' yield identical results.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move SHMLBA to its own header.Joseph Myers2018-10-172-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 some sys/procfs.h headers.Joseph Myers2018-09-251-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Tested with build-many-glibcs.py (again, that does not provide much validation for the correctness of this patch). * sysdeps/unix/sysv/linux/sys/procfs.h: Replace with file based on AArch64 version.

This patch fixes the various bits/sigaction.h headers accordingly. All the fixes are essentially the same, except those for SPARC and Tile. For SPARC, the header (a) spuriously defined various nonstandard macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some standard macros as aliases of nonstandard ones instead of the other way round. This patch fixes the SPARC header to handle these macros the same way and with the same conditions as those for other architectures, so the standard macros are the primary ones and the other ones are defined only for __USE_MISC and are aliases of the standard ones where applicable. For Tile, the header spuriously defined the nonstandard macro SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved to __USE_MISC. (Those nonstandard macros are in a reserved namespace, but it seems desirable to be consistent between architectures as far as possible, and so not define them in standard modes anywhere.)

* Factor out shared definitions from bits/signum.h.Zack Weinberg2017-06-201-62/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the things defined by bits/signum.h are invariant across all supported operating systems. This patch factors out all of them to a new header bits/signum-generic.h, which each bits/signum.h will include and then override whichever things need adjustment. Normally that will mean, at most, adding or changing a few signal numbers. A user-visible side effect is that the obsolete signal constant SIGUNUSED (which is an alias for SIGSYS on all platforms that define it) is no longer exposed by any version of bits/signum.h. A side effect only relevant to glibc hackers is that _NSIG is now defined in terms of __SIGRTMAX, instead of the other way around. This is because __SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is true universally. If your platform doesn't support realtime signals, leave __SIGRTMAX equal to __SIGRTMIN. I also added a Linux-specific test to make sure that our signal constants match the ones in <asm/signal.h>, since we can't use that header (it's not even vaguely namespace-clean). * bits/signum-generic.h: Renamed from bits/signum.h. Add proper multiple include guard and misuse check. Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1. Move definition of SIGIO to "archaic names for compatibility" section. * bits/signum.h: New file which just includes bits/signum-generic.h. * sysdeps/unix/bsd/bits/signum.h * sysdeps/unix/sysv/linux/bits/signum.h * sysdeps/unix/sysv/linux/alpha/bits/signum.h * sysdeps/unix/sysv/linux/hppa/bits/signum.h * sysdeps/unix/sysv/linux/mips/bits/signum.h * sysdeps/unix/sysv/linux/sparc/bits/signum.h Just include <bits/signum-generic.h> and then add or adjust signal constants. Do not define SIGUNUSED, SIGRTMIN, or SIGRTMAX. * signal/Makefile: Install bits/signum-generic.h. * signal/signal.h: Define SIGRTMIN and SIGRTMAX here. * sysdeps/generic/siglist.h: SIGSYS and SIGWINCH are universal. Prefer SIGPOLL to SIGIO. Simplify #ifdeffage. * sysdeps/unix/sysv/linux/tst-signal-numbers.sh: New test. * sysdeps/unix/sysv/linux/Makefile: Run it.
* Remove __need macros from errno.h (__need_Emath, __need_error_t).Zack Weinberg2017-06-141-26/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic. Reorganize file. Declare errno here. When __ASSEMBLER__ is defined, don't declare anything other than the E-constants. * include/errno.h: Change conditional for exposing internal declarations to (not _ISOMAC and not __ASSEMBLER__). * bits/errno.h: Remove logic for __need_Emath. Document requirements for a port-specific bits/errno.h. * sysdeps/unix/sysv/linux/bits/errno.h * sysdeps/unix/sysv/linux/alpha/bits/errno.h * sysdeps/unix/sysv/linux/hppa/bits/errno.h * sysdeps/unix/sysv/linux/mips/bits/errno.h * sysdeps/unix/sysv/linux/sparc/bits/errno.h: Add multiple-include guard and check against improper inclusion. Remove __need_Emath logic. Don't declare errno here. Ensure all constants are defined as simple integer literals. Consistent formatting. * sysdeps/mach/hurd/errnos.awk: Likewise. Only define error_t and enum __error_t_codes if __ASSEMBLER__ is not defined. * sysdeps/mach/hurd/bits/errno.h: Regenerate. * argp/argp.h, string/argz.h: Don't define __need_error_t before including errno.h. * sysdeps/i386/i686/fpu/multiarch/s_cosf-sse2.S * sysdeps/i386/i686/fpu/multiarch/s_sincosf-sse2.S * sysdeps/i386/i686/fpu/multiarch/s_sinf-sse2.S * sysdeps/x86_64/fpu/s_cosf.S * sysdeps/x86_64/fpu/s_sincosf.S * sysdeps/x86_64/fpu/s_sinf.S: Just include errno.h; don't define __need_Emath or include bits/errno.h directly.
* Define SIG_HOLD for XPG4 (bug 21538).Joseph Myers2017-06-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Various bits/signum.h headers define SIG_HOLD if __USE_UNIX98. That should be __USE_XOPEN, as this macro is in XPG4. This patch fixes the conditionals accordingly. Because of other header bugs, this does not allow any XFAILs to be removed (however, the XPG4/signal.h/conform XFAIL only depends on a few such straightforward header bugs, not on the more complicated to fix ucontext_t issues, as ucontext_t isn't included in signal.h in XPG4).

* hppa: Add MAP_HUGETLB and MAP_STACK defines [BZ #19285]Helge Deller2016-01-021-13/+8
| | | | | | | | | The attached patch adds some upstream defines like MAP_HUGETLB and MAP_STACK in mman.h for the hppa architecture. The existing MADV_xxK_PAGES defines were dropped upstream, because they were originally added many years ago based on a proposed patch for the Linux kernel which was never applied. So, this patch drops those unneeded defines.
* Move bits/atomic.h to atomic-machine.h (bug 14912).Joseph Myers2015-09-111-103/+0

This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present).
