linux-user: Translate getsockopt level option
n setsockopt, the socket level options are translated to the hosts' architecture before the real syscall is called, e.g. TARGET_SO_TYPE -> SO_TYPE. This patch does the same with getsockopt. Tested on a x86 host emulating MIPS. Without it:- $ grep getsockopt host.strace 31311 getsockopt(3, SOL_SOCKET, 0x1007 /* SO_??? */, 0xbff17208, 0xbff17204) = -1 ENOPROTOOPT (Protocol not available) With:- $ grep getsockopt host.strace 25706 getsockopt(3, SOL_SOCKET, SO_ERROR, [0], [4]) = 0 Whitespace cleanup: Riku Voipio Signed-off-by: Jamie Lentin <jm@lentin.co.uk> Signed-off-by: Riku Voipio <riku.voipio@iki.fi>
