Description

From bruen...@google.com on May 05, 2011 12:13:27

on win7 net_unittests: /* FIXME i#TOFILE: I'm seeing 0 (AF_UNSPEC) a lot, e.g., with IOCTL_AFD_SET_CONTEXT * where the entire sockaddrs are just zero. Not sure whether to require * that anything beyond sa_family be defined. Sometimes there is further * data and the family is set later. For now ignoring beyond sa_family. */

Original issue: http://code.google.com/p/drmemory/issues/detail?id=386

Contributor guide

Research direction
Investigate the handling of AF UNSPEC sockaddr in Dr. Memory's codebase, particularly in IOCTL AFD SET CONTEXT. Determine if additional data beyond sa family should be defined and update the FIXME accordingly.
