The branch, master has been updated
via f1aa4c3... tsocket_bsd: Always use a real length for the sa_socklen, and keep it around
via 0922c5a... Revert "socket-wrapper: not all systems have FIONREAD defined"
from 3413cf7... Start to plumb smb2 into the oplock system. Calls dummy functions for now.

tsocket_bsd: Always use a real length for the sa_socklen, and keep it around
The previous code assumed the OS would happily accept sizeof(struct
sockaddr_storage). It seems some versions of Solaris do not like
this.

commit 0922c5ab2da1106fdb9a750c2d71d0cd04146394
Author: Stefan Metzmacher <metze at samba.org>

Revert "socket-wrapper: not all systems have FIONREAD defined"
This reverts commit 710aa773d54509de34404f9992c5058ddfa45f3b.
We rely on FIONREAD in a lot of other parts in the code,
so there's no need to have an ifdef for it in the socket_wrapper code.
On tru64 FIONREAD is defined in <sys/ioctl.h>
and we include <sys/ioctl.h> via "system/network.h".
Tridge: maybe a HAVE_SYS_IOCTL_H was missing at the time you tried
it on tru64?
If we find a platform that doesn't support it,
we need to bail out at configure time or
provide a replacement in libreplace.
