Changelog:
corrections:
user-late and group-late, when applied to a pty, affected the system
device /dev/ptmx instead of the pty (thanks to Matthew Cloke for
pointing me to this bug)
socats openssl addresses failed with "nonblocking operation did not
complete" when the peer performed a renegotiation. Thanks to Benjamin
Delpy for reporting this bug.
info message during socks connect showed bad port number on little
endian systems due to wrong byte order (thanks to Peter M. Galbavy for
bug report and patch)
Debian bug 531078: socat execs children with SIGCHLD ignored; corrected
to default. Thanks to Martin Dorey for reporting this bug.
porting:
building socat on systems that predefined the CFLAGS environment to
contain -Wall failed (esp.RedHat). Thanks to Paul Wouters for reporting
this problem and to Simon Matter for providing the patch
support for Solaris 8 and Sun Studio support (thanks to Sebastian
Kayser for providing the patches)
on some 64bit systems a compiler warning "cast from pointer to integer
of different size" was issued on some option definitions
added struct sockaddr_ll to union sockaddr_union to avoid "strict
aliasing" warnings (problem reported by Paul Wouters)

ChangeLog:
V 1.7.1.1:
corrections:
corrected the "fixed possible SIGSEGV" fix because SIGSEGV still might
occur under those conditions. Thanks to Toni Mattila for first
reporting this problem.
ftruncate64 cut its argument to 32 bits on systems with 32 bit long type
socat crashed on systems without setenv() (esp. SunOS up to Solaris 9);
thanks to Todd Stansell for reporting this bug
with unidirectional EXEC and SYSTEM a close() operation was performed
on a random number which could result in hanging e.a.
fixed a compile problem caused by size_t/socklen_t mismatch on 64bit
systems
docu mentioned option so-bindtodev but correct name is so-bindtodevice.
Thanks to Jim Zimmerman for reporting.
docu changes:
added environment variables example to doc/socat-multicast.html
V 1.7.1.0:
new features:
address options shut-none, shut-down, and shut-close allow to control
socat's half close behaviour
with address option shut-null socat sends an empty packet to the peer
to indicate EOF
option null-eof changes the behaviour of sockets that receive an empty
packet to see EOF instead of ignoring it
introduced option names substuser-early and su-e, currently equivalent
to option substuser (thanks to Mike Perry for providing the patch)
corrections:
fixed some typos and improved some comments
V 1.7.0.1:
corrections:
fixed possible SIGSEGV in listening addresses when a new connection was
reset by peer before the socket addresses could be retrieved. Thanks to
Mike Perry for sending a patch.
fixed a bug, introduced with version 1.7.0.0, that let client
connections with option connect-timeout fail when the connections
succeeded. Thanks to Bruno De Fraine for reporting this bug.
option end-close "did not apply" to addresses PTY, SOCKET-CONNECT,
and most UNIX-* and ABSTRACT-*
half close of EXEC and SYSTEM addresses did not work for pipes and
sometimes socketpair
help displayed for some option a wrong type
under some circumstances shutdown was called multiple times for the
same fd

2008/10/15: socat version 1.7.0.0 brings support for SCTP stream, raw
interface, and generic sockets. New option escape allows to interrupt raw
terminal connections. Listening and receiving sockets can set a couple of
environment variables. Added base control of System V STREAMS. Lots of
corrections were performed. socat compiles on Mac OS X again.

Some new features/corrections include:
* new addresses IP-DATAGRAM and UDP-DATAGRAM allow versatile broadcast
and multicast modes

some minor corrections

and slightly modified by me.
socat is a relay for bidirectional data transfer between two
independent data channels. Each of these data channels may be a file,
pipe, device (serial line etc. or a pseudo terminal), a socket (UNIX,
IP4, IP6 - raw, UDP, TCP), an SSL socket, proxy CONNECT connection, a
file descriptor (stdin etc.), the GNU line editor, a program, or a
combination of two of these. These modes include generation of
"listening" sockets, pipes and pseudo terminals.
