2015-08-18Handle ERRNO_BLOCK in fd_driver async functionsSteve Vinoski
Several users on erlang-questions have reported problems with recent releases where output to standard_error causes standard_error_sup to die from receiving an unexpected eagain error. In the fd_driver, change the fd_async() function to handle EINTR, and change fd_ready_async() to handle ERRNO_BLOCK. Add a new test to standard_error_SUITE to generate output to standard_error and ensure that standard_error_sup does not die. Thanks to Kota Uenishi for contributing the test case.

2015-06-09Fix socket option {linger, {true, 0}} to abort TCP connectionsRory Byrne
Up until now, if {linger, {true, 0}} is set on the socket and there is data in the port driver queue, the connection is not aborted until the port queue is empty and close() is called on the underlying file descriptor. This bug allows an idle TCP client to prevent a server from terminating the connection and freeing resources. This patch fixes the problem by discarding the port queue if the socket is closed when {linger, {true, 0}} is set.
2015-06-09Apply 'show_econnreset' socket option to send errors as wellRory Byrne
Up till now all send errors have been translated into a generic {error, closed}. This patch allows {error, econnreset} to be returned on send errors when it is detected that the TCP peer has sent an RST.
2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

2015-06-05Clean up rpc_SUITE:call_benchmark/1Björn Gustavsson
The call_benchmark/1 test case is supposed to return a comment about the number of RPC calls per second, but the return value from the function that produces the comment (do_call_benchmark/4) is ignored. The test case is essentially useless except as a smoke test. Simplify the test case and correct the showing of the number of RPC calls per second, as well as eliminate the use of erlang:now/0.

All of the tests are related to gen_tcp:accept/[1,2] and each of them has the same problem: they ignore the return value of the ?EXPECT_ACCEPTS macro.

It's unnecessary to wait for timeout in some of these testcases. The tests should not check for stray messages while waiting for timeout, that is mostly covered by message order and pattern matching anyway.

2015-05-22Fix parsing of IPv6 addresses to limit leading zerosRory Byrne
The current implementations of inet:parse_ipv6_address/1 and inet:parse_ipv6strict_address/1 permit address strings which have an unlimited number of leading zeros. Addresses such as: "0000000000000000000000000000000ffff::" "::00000000000000000000000000000000000000000000000000000000" "::0000000f435:1" If we are using this facility to validate string representations of IPv6 addresses, then we would end up validating addresses which are non-conformant (with respect to RFC 4291 section 2.2) and potentially dangerous. This patch ensures that each segment of an IPv6 address has a maximum of 4 hex digits.
