I would prefer to not add another arch-specific implementation, but instead use something like __ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL and use accept4 directly in sysdeps/unix/sysv/linux/accept.c. Same for recv and send.
That sounds reasonable. Here is the updated patch. --- 2015-10-14 Stefan Liebler <stli@linux.vnet.ibm.com> * 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.
