* swrap: Treat the case of fd == newfd correctly in dup2()Michael Adam2016-08-231-0/+10

* swrap: Delay addition of child socket_info_fd into socket_info listAnoop C S2016-08-121-2/+1
| | | | | | | | | | | | | | In swrap_accept() we used to add new child socket_info_fd[child_fi] into newly created child socket_info struture[child_si] without considering the fact that we may return early in case of errors from subsequent calls to libc_getsockname() and sockaddr_convert_from_un() during which we free child_fi and child_si and return. So it is better to delay the addition of child_fi into child_si->fds until child_si is completely initialized.

* swrap: Fix sendto() with connected socketsRichard Sharpe2016-05-171-9/+28
| | | | | | | | | | | | | | | | | | | | | | | Let the socket wrapper code work with the net ads dns gethostbyname etc code (lib/addn/dnssock.c) which uses connect on a UDP socket before then using sendto and recvfrom. Here, we make sure we don't error out in that case. Tested by creating a test case for this and then observing that: 1. The test case works when the socket wrapper lib is not being used ie, run the test directly after defining some SHELL variables. 2. That the test case fails when run with the un modified socket wrapper code. 3. Apply this fix and observe that it runs correctly.

| | | | | | | | | | | This worked if the unix path was bigger than sizeof(struct sockaddr_in6). With a short unix socket pathname the buffer was to small to store the address and convert_un_in() failed.
