2011-07-07Fix bug in ets:delete for write_concurrency that could lead to deadlockSverker Eriksson
Relocking in ets_delete_1() and remove_named_tab() was done by unlocking the table without clearing the is_thread_safe flag. A racing thread could then read-lock the table and then incorrectly write-unlock the table as db_unlock() looked at is_thread_safe to determine which kind of lock to unlock. Several fixes: 1. Make db_unlock() use argument 'kind' instead of is_thread_safe to determine lock type. 2. Make relock logic use db_lock() and db_unlock() instead of directly accessing lock primitives. 3. Do ownership transfer earlier in ets_delete_1 to avoid racing owner process to also start deleting the same table.
2011-06-30Fix halfword bug in enif_make_int64Sverker Eriksson
The bug was creating an invalid bignum instead of a small integer, causing strange comparing behavior (=:= failed but == succeeded).

2011-06-08Replace atom in DRV macro in prim_file with stringStavros Aronis
An experimental version of Dialyzer discovered that the atom that replaced the DRV macro in prim_file ends up in calls to erlang:open_port({spawn, Driver}, Portopts) as the Driver argument. The documentation states that this call requires a string there. This change is also consistent with the one introduced in commit 0f03b1e9d2bef3bc830c31a369261af4c5234727 by Kostis Sagonas.

2011-05-24inet: error if fd does not match socket domainMichael Santos
If an IPv4 fd is opened as an IPv6 socket, unexpected behaviour can occur. For example, if an IPv4 UDP socket is opened and passed into Erlang as an IPv6 socket, the first 3 bytes (corresponding to 1 byte representing the protocol family, 2 bytes set to the port) are stripped from the payload. The cause of the UDP payload truncation happens in inet_drv.c:packet_inet_input when a call to inet_get_address fails silently because the family is set to PF_INET6 but the buffer len is the size of an IPv4 struct sockaddr_in. Prevent this behaviour by checking that the protocol family of the file descriptor matches the family of the requested Erlang socket. {ok, S1} = gen_udp:open(0, [binary, inet]), {ok, FD} = inet:getfd(S1), {ok, Port} = inet:port(S1), {ok, S} = gen_udp:open(Port, [binary, {fd, FD}, inet6]), {ok, C} = gen_udp:open(0, [binary]), Msg = <<1,2,3,4,5>>, gen_udp:send(C, "127.0.0.1", Port, Msg), receive {udp, S, _, _, Msg} -> ok; {udp, S, _, _, NewMsg} -> {error, Msg, NewMsg} end. This test results in: {error,<<1,2,3,4,5>>,<<4,5>>} Thanks to Andrew Tunnell-Jones for finding the bug and the test case!
