Subject: [PATCH 1/2] Move closing standard FDs after listen()
|
||
|
|
|
||
|
|
The vsf_sysutil_close() calls need to be moved a bit further so that
|
||
|
|
die() works properly in case listen() fails.
|
||
|
|
|
||
|
|
I see no reason the calls should be placed before listen()
|
||
|
|
specifically, as they are now. My guess is that the author who added
|
||
|
|
the calls thought that listen() is a blocking call, which is not the
|
||
|
|
case. The only thing we need to satisfy is that close() is called
|
||
|
|
before accept, because that is a blocking call. That's all that is
|
||
|
|
needed to fix the bug that was fixed by adding the close() calls.
|
||
|
|
|
||
|
|
