2017-10-08socketcall: fix compile issue with older Linux kernelWaldemar Brodkorb
2017-10-01recvmmsg/sendmmsg: add recvmmsg sendmmsg support.Guo Ren
The recvmmsg and sendmmsg is very important for UDP stream application. If we only use recvmsg for UDP stream, it will only copy one mtu size of data in a syscall. And recvmmsg copy as many as you want in a syscall. So recvmmsg is more efficient,and some applications will depends on the recvmmsg and sendmmsg, eg: UDP media stream player.

2015-11-13i386: use socketcall even if newer linux exposes direct syscallsWaldemar Brodkorb
The changeset 9dea5dc921b5f4045a18c63eb92e84dc274d17eb in the Linux kernel expose the direct syscalls for sockets. For example udhcpc then will use sendto syscall directly and get an EINVAL error. Disable direct syscalls as it was done for SPARC in the past. Musl and GNU libc are not affected, as they already disable direct socket syscalls on i386.

2014-08-18unbreak networking code for sparcWaldemar Brodkorb
This commit 1e2e4ac6193ffe0900bd392fa3c596883771eb34 breaks networking on sparc systems. In Linux the socket functions are declared, but not implemented and must be routed through socketcall(). Tested via Qemu 2.0.0. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2010-09-17libc: Handle cancellation in non multiplexed socket callsCarmelo Amoroso
For those archs that provide non multiplexed socket calls it possible to implement the lib C wrappers without calling the multi-purpose __socketcall. For a subset of these functions that are cancellation point, it needs to correctly handle cancellation.
