[Qemu-devel] [PATCH 21/21] linux-user: remove duplicate tswap32() from do_getsockopt() |

From: Laurent Vivier <address@hidden>
This issue has been detected with tests/linux-tests.c:
linux-test.c:330: getsockopt
327 len = sizeof(val);
328 chk_error(getsockopt(server_fd, SOL_SOCKET, SO_TYPE, &val, &len));
329 if (val != SOCK_STREAM)
330 error("getsockopt");
In linux-user/syscall.c:do_getsockopt(), we have:
...
val = tswap32(val);
...
if (put_user_u32(val, optval_addr))
...
whereas "put_user_u32" calls in the end "__put_user" which uses "tswap32".
So the "val = tswap32(val);" is useless and wrong.
This patch removes it.
