Subject: [PATCH] Use new socket if uid, pid, or gid changes
|
||||
|
||||
The gssproxy daemon uses SO_PEERCRED to determine credentials of the
|
||||
connecting process. However, these credentials are set only at the time
|
||||
connect has called. Therefore they must be reset every time uid or pid
|
||||
changes. For completeness, we check gid as well.

Closes #27
