wraps sendmsg(2) and recvmsg(2) into batch send and receive operation. The goal of this implementation is only to provide API compatibility with Linux. The cancellation behaviour of the functions is not quite right, but due to relative rare use of cancellation it is considered acceptable comparing with the complexity of the correct implementation. If functions are reimplemented as syscalls, the fix would come almost trivial. The direct use of the syscall trampolines instead of libc wrappers for sendmsg(2) and recvmsg(2) is to avoid data loss on cancellation. Submitted by: Boris Astardzhiev <boris.astardzhiev@gmail.com> Discussed with: jilles (cancellation behaviour) MFC after: 1 month
