Subject: Fix incorrect sizeof() in __rpc_getbroadifs
|
||
|
|
|
||
|
|
__rpc_getbroadifs returns bad broadcast addresses on 32bit
|
||
|
|
machines because when copying the broadcast addresses, ite
|
||
|
|
applies the sizeof() operator to a pointer to a sockaddr,
|
||
|
|
rather than the sockaddr itself.
