2011-10-06erts: Fix write-after-free bug in inet driverSverker Eriksson
Bug caught by valgrind but never confirmed as cause of a real problem. Triggered by emulator_test/distribution_SUITE:bad_dist_structure when bad data is received to a distribution port. Port is closed by erts_net_message() and the freed port data is then later used when returning to inet_drv. Everything happens in the same call to tcp_inet_input(). ==32592== Invalid read of size 8 ==32592== at 0x5B6D8C: tcp_deliver (inet_drv.c:8536) ==32592== by 0x5B720E: tcp_recv (inet_drv.c:8652) ==32592== by 0x5B7753: tcp_inet_input (inet_drv.c:8990) ==32592== by 0x5B7FA5: tcp_inet_drv_input (inet_drv.c:9257) ==32592== by 0x4B900C: erts_port_task_execute (erl_port_task.c:856) ==32592== by 0x4AC873: schedule (erl_process.c:5511) ==32592== by 0x5527CA: process_main (beam_emu.c:1225) ==32592== by 0x4A9958: sched_thread_func (erl_process.c:3789) ==32592== by 0x5E2971: thr_wrapper (ethread.c:106) ==32592== by 0x4FEA142: start_thread (in /lib64/libpthread-2.4.so) ==32592== by 0x52C374C: clone (in /lib64/libc-2.4.so) ==32592== Address 0x9b13ea8 is 440 bytes inside a block of size 488 free'd ==32592== at 0x4A1FE94: free (vg_replace_malloc.c:366) ==32592== by 0x58AE69: erts_sys_free (sys.c:2588) ==32592== by 0x48E54F: erts_free (erl_alloc.h:218) ==32592== by 0x497390: driver_free (io.c:3527) ==32592== by 0x5B2E77: inet_stop (inet_drv.c:7152) ==32592== by 0x5B502F: tcp_inet_stop (inet_drv.c:7855) ==32592== by 0x492E60: terminate_port (io.c:1849) ==32592== by 0x493971: erts_do_exit_port (io.c:2059) ==32592== by 0x4CEE01: erts_net_message (dist.c:1508) ==32592== by 0x496AC1: driver_output2 (io.c:3294) ==32592== by 0x5AAA69: inet_port_data (inet_drv.c:1894) ==32592== by 0x5AD57E: tcp_reply_data (inet_drv.c:3181) ==32592== by 0x5B6D84: tcp_deliver (inet_drv.c:8533) ==32592== by 0x5B720E: tcp_recv (inet_drv.c:8652) ==32592== by 0x5B7753: tcp_inet_input (inet_drv.c:8990) Fixed by checking the negative return code earlier in tcp_deliver().

2011-06-08Teach prim_file:list_dir/1,2 to use fname chunksBjörn-Egil Dahlberg
The efile driver will now use chunked data on list_dir. This will lessen the number of sends to prim_file and hence improve performance. This method is utilized in both direct and async cases.
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!

2011-02-21Add patch from Per HedelandPatrik Nyblom
Per H @ Tail-f: The original code here had problems that possibly only occur if you abuse it for non-INET sockets, but anyway: a) If the getsockopt for SO_PRIORITY or IP_TOS failed, the actual requested setsockopt was never even attempted. b) If {get,set}sockopt for one of IP_TOS and SO_PRIORITY failed, but ditto for the other worked and that was actually the requested option, failure was still reported to erlang.

The AI_V4MAPPED flag is falling out of grace in modern IPv6 stacks, for security reasons, e.g. FreeBSD do not document it any longer. The AI_ADDRCONFIG flag have got unclear semantics on the same OS.
