According to Stevens UNIX Network Programming and various other sources, the correct handling for non-blocking connect() is: - when the initial connect() return -1/EINPROGRESS polling the socket for *writeability* - in the poll handler call getsocktopt() with SO_ERROR to get the finished connect() return value Simply calling connect() a second time without error checking is probably wrong and not portable. For a successfull connect() Linux returns 0, but Solaris will return EISCONN: 24254: 0.0336 0.0002 connect(4, 0xFEFFECAC, 16, SOV_DEFAULT) Err#150 EINPROGRESS 24254: AF_INET name = 10.10.10.143 port = 1024 24254: 0.0349 0.0001 port_associate(3, 4, 0x00000004, 0x0000001D,0x080648A8) = 0 24254: 0.0495 0.0146 port_getn(3, 0xFEFFEB50, 1, 1, 0xFEFFEB60) = 1 [0] 24254: 0.0497 0.0002 connect(4, 0x080646E4, 16, SOV_DEFAULT) Err#133 EISCONN 24254: AF_INET name = 10.10.10.143 port = 1024 Bug: https://bugzilla.samba.org/show_bug.cgi?id=11564 Signed-off-by: Ralph Boehme <slow@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
