2011-12-01Fix offset calculation for darwinLukas Larsson
2011-12-01Fix cleanup for sendfileLukas Larsson
2011-12-01Fix 32 bit parametersLukas Larsson
2011-12-01Make socket blocking if there are async threadsLukas Larsson
2011-12-01Implement sendfile when there are no async threadsLukas Larsson
When there are no async threads sendfile will use the ready_output select on the socket fd to know when to send data. The file_desc will also be put in the sending sendfile_state which buffers all other commands to that file until the sendfile is done.
2011-12-01Implement blocking calls for sendfileLukas Larsson
Move sendfile data to invoke data instead of file_descr. Remove usage of ready_output when doing a send. If told to send 0 bytes, file_sendfile now sends the entire file for linux.
2011-12-01Remove output from driver entryLukas Larsson
outputv will always be used so removed output to decrease confusion.
2011-12-01Implement sendfile using blocking io in asynch threadsLukas Larsson
Move the command handling to outputv in preparation for header and trailer inclusion in the sendfile api. Use the standard efile communication functions for sendfile.
2011-11-29Implement file:sendfileTuncer Ayaz
Allow Erlang code to use sendfile() where available by wrapping it as file:sendfile/4 and file:sendfile/2. sendfile(2) - Linux man page: "sendfile() copies data between one file descriptor and another. Because this copying is done within the kernel, sendfile() is more efficient than the combination of read(2) and write(2), which would require transferring data to and from user space."

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().

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!
