Alex Copot aacd9289af tcp: bind() use stronger condition for bind_conflict ... We must try harder to get unique (addr, port) pairs when doing port autoselection for sockets with SO_REUSEADDR option set. We achieve this by adding a relaxation parameter to inet_csk_bind_conflict. When 'relax' parameter is off we return a conflict whenever the current searched pair (addr, port) is not unique. This tries to address the problems reported in patch: 8d238b25b1 Revert "tcp: bind() fix when many ports are bound" Tests where ran for creating and binding(0) many sockets on 100 IPs. The results are, on average: * 60000 sockets, 600 ports / IP: * 0.210 s, 620 (IP, port) duplicates without patch * 0.219 s, no duplicates with patch * 100000 sockets, 1000 ports / IP: * 0.371 s, 1720 duplicates without patch * 0.373 s, no duplicates with patch * 200000 sockets, 2000 ports / IP: * 0.766 s, 6900 duplicates without patch * 0.768 s, no duplicates with patch * 500000 sockets, 5000 ports / IP: * 2.227 s, 41500 duplicates without patch * 2.284 s, no duplicates with patch Signed-off-by: Alex Copot <alex.mihai.c@gmail.com> Signed-off-by: Daniel Baluta <dbaluta@ixiacom.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
