  1. Fix compilation on Solaris

    authored
    So errno is not thread local on Solaris and is set to 0 by default on
    error. Really Solaris?
    
    On Solaris, compile using POSIX mode which requires c99 mode which fixes
    errno, uses void* instead of c_addr_t* for iovec and various other errors.
    
    Add solaris constants for dgram, stream and raw which differ from other
    unix platforms. Make the send/recvmsg example work on Solaris.
    
    Platform dependent constants need to be fixed in the future. This could
    be done either by adding a lookup table to the NIF or writing a small
    program in C to generate an erlang module at compile time.
    
    Bump version to 0.6.1.

  1. Add sendmsg/4,5 and recvmsg/4,5

    authored
    Some small fixes and interface changes to sendmsg/5 and recvmsg/4 based
    on the pull request by Andrew Thompson:
    
    #18
    
    * recvmsg: the msg_namelen field is value-result. Resize the source
      address binary to this length. Fixes einval on FreeBSD when passing
      in an overlong socket address as noted in the sendmsg/recvmsg echo
      example
    
    * recvmsg: account for padding in cmsghdr structure when calculating the
      cmsg data length.
    
    * recvmsg: reverse the list of cmsg tuples so the order is the same as
      returned using the CMSG_NXTHDR() macro
    
    * recvmsg: if bufsize or ctrlsize are 0, set the iov_base or msg_name
      to NULL instead of a 0 byte binary
    
    * sendmsg: if buf or sa are empty binaries, set iov_base or msg_name to
      NULL
    
    * cleanup: fix pasto in arg order, memory leaks, change recvmsg to return
      msg_flags as a signed int
    
    The following alterations were made to the interface:
    
    * recvmsg/5: add an extra argument to recvmsg to specify the size
      of sockaddr
    
      recvmsg() with a connected socket and a non-NULL msg_name field
      in the msghdr structure will return EISCONN.
    
      Allow the caller to specify the length of the sockaddr structure (for
      example, 128 bytes is the size of sockaddr_storage which is large enough
      to hold any socket address).
    
      Add recvmsg/4, a version of recvmsg for connected sockets that defaults
      to setting msg_name to NULL.
    
    * recvmsg/sendmsg: make the arg order consistent
    
      Change the order of arguments so the input and output values are in the
      same order and position, recvmsg and sendmsg provide the same order and
      the order reflects sendto()/recvfrom().
    
      The order for arguments and return values is:
    
      * buffer
      * flags
      * control data
      * socket address
    
    TODO: Solaris support
    
    Thanks @Vagabond!

    Fix sendmsg/recvmsg on FreeBSD/NetBSD/OpenBSD

    Vagabond authored
    Some padding/length issues needed to be fixed, but now the
    sendmsg/recvmsg echo test works on all 3 BSDs and on Linux.
  2. @Vagabond

    Make sendmsg and recvmsg actually usable

    Vagabond authored
    Instead of passing in a binary that is treated as the 'msghdr' struct,
    pass in data needed to construct an appropriate msghdr struct and also
    return useful result data, including the control data.
    
    Documentation and an example are also included.

  1. sendmsg/recvmsg; return the number of bytes

    authored
    Return the number of bytes sent/received. The msghdr structure contains
    a pointer to an iovec which may consist of several buffers. The sendmsg
    and recvmsg NIFs are not aware of the size and number of the buffers.

  1. Add support for sendmsg/recvmsg

    authored
    In preparation for support of socket ancillary data (RFC3542, Unix
    sockets, ...), add support for sendmsg(2) and recvmsg(2).
    
    recvmsg/3 and sendmsg/3 require a struct msghdr to be prepared
    containing pointers to allocated memory (to be read into and to be
    read from respectively). This buffer will have to be allocated using
    procket:alloc/1.

  2. Figure out how to run procket setuid helper

    authored
    Modify the way the procket external setuid helper binary is called based
    on:
    
    * whether a progname has explicitly been passed in (run the command
      immediately)
    
    * if the procket helper is setuid/setgid (run the command immediately)
    
    * if a device is requested to be opened, check the access rights of the
      process (if read/write, run command immediately)
    
    * otherwise, use sudo

  1. Add support for getsockname(2)

    authored
    Support getsockname(2) for netlink. When a netlink socket is opened,
    it uses getsockname to find it's address.
    
    The inet module has sockname/1 which would be the usual way of get the
    address. In this case, the inet module rejects the netlink socket.

  1. libancillary: fix alignment of control message

    authored
    Transferring fd's between processes was failing. Disabling compiler
    optimizations resulted in a segfault when ancil_send_fd was called and
    on one occasion, a kernel panic (after playing with the cmsg lengths).
    
    Align the buffer using a union as suggested in UNP. Don't use the
    libancillary structure for holding the fd's; use a union allocated on the
    stack and calculate lengths using the macros. This change only supports
    passing a single fd between processes so it isn't a proper fix.

  1. writev: fix compile error

    authored
    Include header file for writev. Also remove duplicate include.
  2. ioctl: allow integer values for argp

    authored
    The third argument to ioctl is usually a pointer but the FreeBSD man
    page clarifies:
    
        Most uses of ioctl(), however, require the third argument to be a
        caddr_t or an int.
    
    (The size and signedness of the int is not specified.)
    
    For example, tun/tap devices on Linux set persist mode using the integer
    value 0 or non-zero.
    
    Unfortunately, allowing integer values allows the caller to mistakenly
    pass in an integer where a pointer is required. While this will probably
    result in EFAULT or EINVAL, there's a chance the memory of the process
    could be corrupted.
    
    Whitelisting ioctl requests with integer values wouldn't be practical
    since procket would need to know about every driver.

  1. Mac OS X: ensure tun/tap device is non-blocking

    authored
    On OS X, reads from a tun dev block even with the O_NONBLOCK flag set
    on open. Work around this by setting non-blocking mode after open.
