[Qemu-devel] [PATCH] qemu-user: Translate getsockopt level option |
Date: |
Wed, 17 Nov 2010 12:30:48 +0000 (GMT) |
User-agent: |
Alpine 2.00 (DEB 1167 2008-08-23) |
In 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
