S390: Call direct system calls for socket operations.
|
|
|
|
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.
|
|
|
|
|
|
The removal is required due to the kernel change because otherwise,
|
|
these system calls will be used unconditionally with new kernel
|
|
headers.
