Bug #: 29164
Summary: Swap buffers in GetAcceptExSockaddrs
(WS2_async_accept).
Product: Wine
Version: 1.3.33
Platform: All
OS/Version: All
Status: UNCONFIRMED
Severity: blocker
Priority: P2
Component: winsock
AssignedTo: wine-bugs at winehq.org
ReportedBy: admin at myac.msk.ru
Classification: Unclassified
Bug occurs since version 1.3.12.
The functions of WS2_async_accept used the wrong procedure for filling the
buffer. Should be reversed and local_addr remote_addr!!!
Should be as follows:
/* WS2 Spec says size param is extra 16 bytes long...what do we put in it?
*/
addr = ((char *)wsa->buf) + wsa->data_len;
len = wsa->local_len - sizeof(int);
- WS_getpeername(HANDLE2SOCKET(wsa->accept_socket),
+ WS_getsockname(HANDLE2SOCKET(wsa->accept_socket),
(struct WS_sockaddr *)(addr + sizeof(int)), &len);
*(int *)addr = len;
addr += wsa->local_len;
len = wsa->remote_len - sizeof(int);
- WS_getsockname(HANDLE2SOCKET(wsa->accept_socket),
+ WS_getpeername(HANDLE2SOCKET(wsa->accept_socket),
(struct WS_sockaddr *)(addr + sizeof(int)), &len);
*(int *)addr = len;
