2017-03-09Consolidate Linux send implementationAdhemerval Zanella
This patch consolidates the send Linux syscall implementation on sysdeps/unix/sysv/linux/send{to}.c. The changes are: 1. Remove send from auto-generation syscalls.list on the architecture that uses __NR_send. 2. Define __NR_send for architectures that supports it. It was done instead of defining in default kernel-features.h because current Linux practice for new ports are to implement only __NR_sendto [1] and it will require adding new kernel-features for ports that do not require it (aarch64 for instance). 3. Remove __ASSUME_SENDTO_FOR_SEND_SYSCALL and decide to use __NR_sendto for send generation based on __ASSUME_SENDTO_SYSCALL. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Define. * sysdeps/unix/sysv/linux/aarch64/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Undefine. * sysdeps/unix/sysv/linux/nios2/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Likewise. * sysdeps/unix/sysv/linux/tile/sysdep.h (HAVE_INTERNAL_SEND_SYMBOL): Likewise. * sysdeps/unix/sysv/linux/alpha/kernel-features.h (__ASSUME_RECV_SYSCALL): Define. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/hppa/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/ia64/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h (__ASSUME_RECV_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Remove define. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_SENDTO_FOR_SEND_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Remove send from auto-generation list. * sysdeps/unix/sysv/linux/arm/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/hppa/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewike. * sysdeps/unix/sysv/linux/mips/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/send.c: Simplify includes.

2016-12-28Add __ASSUME_DIRECT_SYSVIPC_SYSCALL for LinuxAdhemerval Zanella
On current minimum supported kernels, the SysV IPC on Linux is provided by either the ipc syscalls or correspondent wire syscalls. Also, for architectures that supports wire syscalls all syscalls are supported in a set (msgct, msgrcv, msgsnd, msgget, semctl, semget, semop, semtimedop, shmctl, shmat, shmget, shmdt). The architectures that only supports ipc syscall are: - i386, m68k, microblaze, mips32, powerpc (powerpc32, powerpc64, and powerpc64le), s390 (32 and 64 bits), sh, sparc32, and sparc64. And the architectures that only supports wired syscalls are: - aarch64, alpha, hppa, ia64, mips64, mips64n32, nios2, tile (tilepro, tilegx, and tilegx64), and x86_64 Also arm is the only one that supports both wire syscalls and the ipc, although the ipc one is deprecated. This patch adds a new define, __ASSUME_DIRECT_SYSVIPC_SYSCALL, that wired syscalls are supported on the system and the general idea is to use it where possible. I also checked the syscall table for all architectures on Linux 4.9 and there is no change on described support for Linux 2.6.32/3.2. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): New define. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Undef. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/mips/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h (__ASSUME_DIRECT_SYSVIPC_SYSCALL): Likewise.
2016-05-25Adjust kernel-features.h defaults for recvmsg and sendmsgAdhemerval Zanella
This patch removes the auto-generation for recvmsg and sendmsg syscall and adjust the kernel-features.h for all architectures supported on Linux. This patch follows the idea of 'Adjust kernel-features.h defaults for socket syscalls.' (35ade9f11b9007ee9683529f2d33698ff35255c8) by define __ASSUME_SENDMSG_SYSCALL and __ASSUME_RECVMSG_SYSCALL as supported by default and undefine it for the architecture that do not support it directly. The main rationale is to make is easier add code wrapper over the syscall to fix BZ#16919 (recvmsg standard compliance).

2016-03-15Adjust kernel-features.h defaults for socket syscalls.Joseph Myers
This patch adjusts the defaults for kernel-features.h macros relating to availability of accept4, recvmmsg and sendmmsg. It is not intended to affect which macros end up getting defined in any configuration. At present, all architectures with syscalls for those functions need to define __ASSUME_*_SYSCALL macros; in particular, any new architecture needs its own kernel-features.h file for that purpose, though it may not otherwise need such a header. Those macros are then used together with __ASSUME_SOCKETCALL to define macros for whether the functions in question are available. This patch changes the defaults so that the syscalls are assumed to be available by default with recent-enough kernels, and it is the responsibility of architecture headers to undefine the macros if they are unavailable in supported kernels at least as recent as the version where the architecture-independent functionality was introduced. The __ASSUME_<function> macros are defaulted similarly instead of being defined based on other macros (defining based on other macros would no longer work because the #undefs appear after the generic header is included), so where the syscall being unavailable means the function is unavailable this means the architecture header has to undefine the __ASSUME_<function> macro; this only affects __ASSUME_ACCEPT4 for ia64, as other cases where the syscalls were added late enough to be relevant with current kernel version requirements are all on socketcall architectures. As a consequence, the AArch64 and Nios II kernel-features.h header files are removed, and others simplified. When the minimum kernel version becomes 4.3 or later on all architectures, the syscalls in question can just be assumed unconditionally, permitting further simplification. Tested for x86_64, x86 and powerpc (that installed shared libraries are unchanged by the patch, and testsuite for x86_64 and x86). * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ACCEPT4_SYSCALL): Define unconditionally.

2015-11-09S390: Call direct system calls for socket operations.Stefan Liebler
this patch calls direct system calls for socket operations in the same way as power does. The system calls were introduced in kernel commit https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=977108f89c989b1eeb5c8d938e1e71913391eb5f. There are no direct recv, send, accept syscalls available on s390. Thus recvfrom, sendto, accept4 are called instead of the socketcall by defining __ASSUME_*_FOR_*_SYSCALL macros. See recv.c, send.c, accept.c in sysdeps/unix/sysv/linux/ folder. The socketcalls in syscalls.list for s390-64 are removed. They were never used on s390x. ChangeLog: * sysdeps/unix/sysv/linux/s390/kernel-features.h: (__ASSUME_*_SYSCALL) Define new macros. * sysdeps/unix/sysv/linux/s390/s390-64/syscalls.list: Remove socketcall syscalls. * sysdeps/unix/sysv/linux/accept.c (__libc_accept): Use accept4 if defined __ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL. * sysdeps/unix/sysv/linux/recv.c (__libc_recv): Use recvfrom if defined __ASSUME_RECVFROM_FOR_RECV_SYSCALL. * sysdeps/unix/sysv/linux/send.c (__libc_send): Use sendto if defined __ASSUME_SENDTO_FOR_SEND_SYSCALL.
