Handle EMSGSIZE on UNIX domain sockets.
On some systems (eg, FreeBSD) the default SO_SNDBUF for UNIX domain sockets is to small, and EMSGSIZE is returned. Other systems provide a larger default send buffer, but there is still no guarantee that the buffer will be sized appropriately. This patch modifies the sendto() path to attempt to resize the SO_SNDBUF dynamically upon an EMSGSIZE failure, and then retry the send. This fixes local DCE/RPC errors on FreeBSD, eg: https://lists.samba.org/archive/samba-technical/2013-January/089881.html Signed-Off-By: Landon Fuller <landonf@bikemonkey.org> Reviewed-by: Andrew Bartlett <abartlet@samba.org> Autobuild-User(master): Andrew Bartlett <abartlet@samba.org> Autobuild-Date(master): Sat Mar 2 23:34:03 CET 2013 on sn-devel-104
