Changes:
1.7.4.0
-------
Security:
Buffer size option (-b) is internally doubled for CR-CRLF conversion,
but not checked for integer overflow. This could lead to heap based
buffer overflow, assuming the attacker could provide this parameter.
Test: BLKSIZE_INT_OVERFL
Thanks to Lê Hiếu Bùi for reporting this issue and sending an
example exploit.
Corrections:
Socats address parser read over end of string when there were unbalanced
quotes
Test: UNBALANCED_QUOTE
Removed unused usleep() call from sycls.c
Unsetenv() was conditional in sysutils.c but not in xio-openssl.c thus
building failed on Solaris 9.
Thanks to Greg Earle for reporting this issue and providing a patch.
Mitigated race condition of quickly terminating SYSTEM or EXEC child
processes.
Option o-direct might require alignment of read/write buffer to, e.g.,
512 bytes, Socat now takes care of this when allocating the buffer.
With this fix read() succeeds, however, write() still might fail when
not writing complete pages.
Test: O_DIRECT
There was a race condition in the way Socat UDP-RECVFROM and similar
addresses with option fork prevents one packet from triggering
multiple processes. The symptom was that Socat master process seemed to
hang and did not process further packets. The fix makes use of
pselect() system call.
Thanks to Fulvio Scapin for reporting this issue.
UNIX domain client addresses applied file system entry options (group
NAMED) to the server socket instead of the client (bind) socket entry.
Tests: UNIX_SENDTO_UNLINK UNIX_CONNECT_UNLINK
Thanks to Nico Williams for reporting this major issue.
Length of single address options was limited to 511 bytes. This value
is now increased to 2047 bytes.
Change suggested by Mario Camou.
Addresses of type RECVFROM with option fork looped with an error
message in case that the second address failed before consuming the
packet. The fix makes RECVFROM drop the packet when the second address
failed before reading it. Use retry or forever option with the second
address if you want to avoid data loss.
Thanks to Chunmei Xu for reporting this issue and proving the patch.
Socats DTLS implementation has been reworked and appears to work now
reasonably over UDP.
New addresses: OPENSSL-DTLS-SERVER (DTLS-L),
OPENSSL-DTLS-CLIENT (DTLS)
Tests: OPENSSL_DTLS_CLIENT OPENSSL_DTLS_SERVER
OPENSSL_METHOD_DTLS1 OPENSSL_METHOD_DTLS1.2
Thanks to Brandon Carpenter, Qing Wan, and Pavel Nakonechnyi for
sending patches.
filan did not output the socket protocol.
filan -s assumed each stream socket to be TCP and each datagram socket
to be UDP. Now it uses SO_PROTOCOL and getprotoent() for correct output.
Help text showed two parameters for UDP4-RECVFROM address, but only
<port> is allowed.
Thanks to John the Scott for reporting this issue.
Error messages from SSL_read() and SSL_write() sometimes stated
SSL_connect instead of originating function name.
Fixed some more non functional minor issues.
Porting:
In gcc version 10 the default changed from -fcommon to -fno-common.
Consequently, linking filan and procan failed with error
"multiple definition of `deny_severity'" and `allow_severity'
Fixed by removing definitions in filan.c and procan.c
Debian issue 957823
Thanks to László Böszörményi and others for reporting this issue.
Solaris 9 does not provide strndup(); added substitute code.
Thanks to Greg Earle for providing a patch.
Added configure option --enable-openssl-base to specify the location of
a non-OS OpenSSL installation
There are systems whose kernel understands SCTP but getaddrinfo does
not. As workaround after EIA_SOCKTYPE on name and service resolution
fall back to ai_socktype=0; if it fails with EAI_SERVICE, set
ai_protocol=0 and try again
Test: SCTP_SERVICENAME
Per file filesystem options were still name ext2-* and depended on
<linux/ext2_fs.h>. Now they are called fs-* and depend on <linux/fs.h>.
These fs-* options are also available on old systems with ext2_fs.h
New options openssl-min-proto-version (min-version) and
openssl-max-proto-version (max-version) give access to the related
OpenSSL set-macros and substitute deprecated version-specific methods.
Test: OPENSSL_MIN_VERSION
With OpenSSL use OPENSSL_init_SSL when available, instead of deprecated
SSL_library_init.
With OPENSSL_API_COMPAT=0x10000000L the files openssl/dh.h, openssl/bn.h
must explicitely be included.
Thanks to Rosen Penev for reporting and sending a patch.
Testing:
test.sh now produces a list of tests that could not be performed for
any reason. This helps to analyse these cases.
OpenSSL s_server appearently started to neglect TCPs half close feature.
Test OPENSSL_TCP4 has been changed to tolerate this.
OpenSSL changed its behaviour when connection is rejected. Tests
OPENSSLCERTSERVER, OPENSSL_CN_CLIENT_SECURITY, and
OPENSSL_CN_SERVER_SECURITY now tolerate this.
OpenSSL no longer allows explicit renegotiation with TLSv1.3, thus the
appropriate tests failed.
Fix: use TLSv1.2 for renegotiation tests
Tests: OPENSSLRENEG1 OPENSSLRENEG2
Ubuntu 20.04 requires 2048 bit certificates with OpenSSL
Archlinux 2020 has not which command; its ip,ss commands have modified
version strings
More testing issues solved:
* ss to pipe might omit column separator
* UDP6MULTICAST_UNIDIR fails on newer Linux kernels
* do not use sort -V
* renamed testaddrs() to testfeats(), and introduced new testaddrs()
New features:
GOPEN and UNIX-CLIENT addresses now support sockets of type SEQPACKET.
Test: GOPENUNIXSEQPACKET
Feature suggested by vi0oss.
The generic setsockopt-int and related options are, in case of
listening/accepting addresses, applied to the connected socket(s). To enable
setting options on the listening socket, a new option setsockopt-listen
has been implemented. See the documentation for info on data types.
Tests: SETSOCKOPT SETSOCKOPT_LISTEN
Thanks to Steven Danna and Korian Edeline for reporting this issue.
Filan option -S gives short description like -s but with improved
format
Socat OpenSSL client, when server was specified using IP address, did
not verify connection on certificates SubjectAltName IP entries.
Tests: OPENSSL_SERVERALTAUTH OPENSSL_SERVERALTIP4AUTH OPENSSL_SERVERALTIP6AUTH
Fixes Red Hat bug 1805132
Added options -r and -R for raw dump of transferred data to files.
Test: OPTION_RAW_DUMP
Added option ip-transparent (socket option IP_TRANSPARENT)
Thanks to Wang Shanker for sending a patch.
OPENSSL-CONNECT now automatically uses the SNI feature, option
openssl-no-sni turns it off. Option openssl-snihost overrides the value
of option openssl-commonname or the server name.
Tests: OPENSSL_SNI OPENSSL_NO_SNI
Thanks to Travis Burtrum for providing the initial patch
New option accept-timeout (listen-timeout)
Test: ACCEPTTIMEOUT
Proposed by Roland
New option ip-add-source-membership
Feature inspired by Brian (b f31415)
INCOMPATIBLE CHANGE: Address UDP-DATAGRAM now does not check peerport
of replies, as it did up to version 1.7.3.4. Use option sourceport when
you need the old behaviour.
Test: UDP_DATAGRAM_SOURCEPORT
Feature inspired by Hans Bueckler for SSDP inquiry (for UPnP)
New option proxy-authorization-file reads PROXY-CONNECT credentials
from file and makes it possible to hide this data from the process
table.
Test: PROXYAUTHFILE
Thanks to Charles Stephens for sending an initial patch.
Added AF_VSOCK support with VSOCK-CONNECT and VSOCK-LISTEN addresses.
Developed by Stefano Garzarella.
Coding:
Added printf formats for uint16_t etc.
Documentation:
Address UDP-RECV does not support option fork.
Thanks to Fulvio Scapin for reporting that mistake in docu.
TUN address documentation showed TCP for backend which may merge
consecutive packets which causes data loss.
Thanks to Tomasz Lakota for reporting this issue.

####################### V 1.7.3.4:
Corrections:
Header of xiotermios_speed() declared parameter unsigned int instead of
speed_t, thus compiling failed on MacOS
Thanks to Joe Strout and others for reporting this bug.
Thanks to Andrew Childs and others for sending a patch.
Under certain circumstances, termios options of the first address were
applied to the second address, resulting in error
"Inappropriate ioctl for device"
This affected version 1.7.3.3 only.
Test: TERMIOS_PH_ALL
Thanks to Ivan J. for reporting this issue.
Socat failed to compile when no poll() system call was found by
configure.
Thanks to Jason White for sending a patch.
Due to use of SSL_CTX_clear_mode() Socat failed to compile on old
systems with, e.g., OpenSSL-0.9.8. Thanks to Simon Matter and Moritz B.
for reporting this problem and sending initial patches.
getaddrinfo() in IP4-SENDTO and IP6-SENDTO addresses failed with
"ai_socktype not supported" when protocol 6 was addressed.
The fix removes the possibility to use service names with SCTP.
Test: IP_SENDTO_6
Thanks to Sören for sending an initial patch.
Under certain circumstances, Socat printed the "socket ... is at EOF"
multiple times.
Test: MULTIPLE_EOF
Newer parts of test.sh used substitutions ${x,,*} or ${x^^*} that are
not implemented in older bash versions.

pkgsrc changes:
- Adjust test related definition
- Remove no longer needed patches
Changes:
1.7.3.3:
--------
Corrections:
Makefile.in did not specify dependencies of filan on vsnprintf_r.o
and snprinterr.o
Added definition of FILAN_OBJS
Thanks to Craig Leres, Clayton Shotwell, and Chris Packham for
providing patches.
configure option --enable-msglevel did not work with numbers
The autoconf mechanism for determining SHIFT_OFFSET did not work when
cross compiling.
Thanks to Max Freisinger from Gentoo for sending a patch.
Socat still depended on obsolete gethostbyname() function, thus
compiling with MUSL libc failed.
Problem reported by Kennedy33.
The async signal safe diagnostic system used FDs 3 and 4 internally, so
use of appropriate fdin or fdout led to failures.
Test: DIAG_FDIN
Problem reported by Onur Sentürk.
The socket based mechanism for passing messages and signal information
from signal handler to process could reach and kill the wrong process.
Introduces functions diag_sock_pair(), diag_fork()
Thanks to Darren Zhao for analysing and reporting this problem.
Option ipv6-join-group did not work because it was applied in the wrong
phase
Test: UDP6MULTICAST_UNIDIR
Thanks to Angus Gratton for sending a patch.
Setting ispeed and ospeed failed for some serial devices because the
two settings were applied with two different get/set cycles, Thanks to
Alexandre Fenyo for providing an initial patch.
However, the actual fix is part of a conceptual change of the termios
module that aims for applying all changes in a single tcsetaddr call.
Fixes FreeBSD Bug 198441
Termios options TAB0,TAB1,TAB2,TAB3, and XTABS did not have an effect.
Thanks to Alan Walters for reporting this bug.
Substituted cumbersom ISPEED_OFFSET mechanism for cfsetispeed() calls
With TCP6-LISTEN and the other passive IPv6 addresses the range option
just failed: due to a bug in the syntax parser and two more bugs in
the xiocheckrange_ip6() function.
The syntax has now been changed from "[::1/128]" to "[::1]/128"!
Thanks Leah Neukirchen for sending an initial fix.
For name resolution Socat only checked the first character of the host
name to decide if it is an IPv4 address. This was not RFC conform. This
fix removes the possibility for use of IPv4 addresses with IPv6, e.g.
TCP6:127.0.0.1:80
Thanks to Nicolas Fournil for reporting this issue.
Print a useful error message when single character options appear to be
merged in Socat invocation
Test: SOCCAT_OPT_HINT
Fixed some docu typos.
Thanks to Travis Wellman, Thomas <tjps636>, Dan Kenigsberg,
Julian Zinn, and Simon Matter
Porting:
OpenSSL functions TLS1_client_method() and similar are
deprecated. Socat now uses recommended TLS_client_method(). The old
functions and dependend option openssl-method can still be
used when configuring socat with --enable-openssl-method
Shell scripts in socat distribution are now headed with:
#! /usr/bin/env bash
to make them better portable to systems without /bin/bash
Thanks to Maya Rashish for sending a patch
RES_AAONLY, RES_PRIMARY are deprecated. You can still enable them with
configure option --enable-res-deprecated.
New versions of OpenSSL preset SSL_MODE_AUTO_RETRY which may hang socat.
Solution: clear SSL_MODE_AUTO_RETRY when it is set.
Renamed configure.in to configure.ac and set an appropriate symlink for
older environments.
Related Gentoo bug 426262: Warning on configure.in
Thanks to Francesco Turco for reporting that warning.
Fixed new IPv6 range code for platforms without s6_addr32 component.
Testing:
test.sh: Show a warning when phase-1 (insecure phase) of a security
test fails
OpenSSL tests failed on actual Linux distributions. Measures:
Increased key lengths from 768 to 1024 bits
Added test.sh option -C to delete temp certs from prevsious runs
Provide DH-parameter in certificate in PEM
OpenSSL s_server option -verify 0 must be omitted
OpenSSL authentication method aNULL no longer works
Failure of cipher aNULL is not a failure
Failure of methods SSL3 and SSL23 is desired
test.sh depended on ifconfig and netstat utilities which are no longer
available in some distributions. test.sh now checks for and prefers
ip and ss.
Thanks to Ruediger Meier for reporting this problem.
More corrections to test.sh:
Language settings could still influence test results
netstat was still required
Suppress usleep deprecated messag
Force use of IPv4 with some certificates
Set timeout for UDPxMAXCHILDREN tests
Git:
Added missing Config/Makefile.DragonFly-2-8-2,
Config/config.DragonFly-2-8-2.h
Removed testcert.conf (to be generated by test.sh)
Cosmetics:
Simplified handling of missing termios defines.
New features:
Permit combined -d options as -dd etc.
|
|
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

pkgsrc changes:
- Take MAINTAINERship
Changes:
1.7.3.2
-------
corrections:
- SIGSEGV and other signals could lead to a 100% CPU loop
- Failing name resolution could lead to SIGSEGV
Thanks to Max for reporting this issue.
- Include <stddef.h> for ptrdiff_t
Thanks to Jeroen Roovers for reporting this issue.
- Building with --disable-sycls failed due to missing sslcls.h defines
Socat hung when configured with --disable-sycls.
- Some minor corrections with includes etc.
- Option so-reuseport did not work. Thanks to Some Raghavendra Prabhu
for sending a patch.
- Programs invoked with EXEC, nofork, and -u or -U had stdin and stdout
incorrectly assigned
Test: EXEC_NOFORK_UNIDIR
Thanks to David Reiss for reporting this problem.
- Socat exited with status 0 even when a program invoked with SYSTEM or
EXEC failed.
Tests: SYSTEM_RC EXEC_RC
Issue reported by Felix Winkelmann.
- AddressSanitizer reported a few buffer overflows (false positives).
Nevertheless fixed Socat source.
Issue reported by Hanno Böck.
- Socat did not use option ipv6-join-group.
Test: USE_IPV6_JOIN_GROUP
Thanks to Linux Lüssing for sending a patch.
- UDP-LISTEN did not honor the max-children option.
Test: UDP4MAXCHILDREN UDP6MAXCHILDREN
Thanks to Leander Berwers for reporting this issue.
- Options so-rcvtimeo and so-sndtimeo do not work with poll()/select()
and therefore were useless.
Thanks to Steve Borenstein for reporting this issue.
- Option dhparam was documented as dhparams. Added the alias name
dhparams to fix this.
Thanks to Alexander Neumann for sending a patch.
- Options shut-down and shut-close did not work.
Thanks to Stefan Schimanski for providing a patch.
- There was a bug in printing readline log message caused by a misleading
indentation.
Thanks to Paul Wouters for reporting.
- The internal vsnprintf_r function looped or crashed on size parameter
with hexadecimal output.
- Ignore exit code of child process when it was killed by master due to
EOF
- Corrected byte order on read of IPV6_TCLASS value from ancillary
message
- Fixed type of the bool element in options. This had bug caused failures
e.g. of ignoreeof on big-endian systems when bool was not based on int.
- On systems with predefined bool type whose size differs from int some
IPv6 and TCP options (per setsockopt()) failed.
- Length of integral data in ancillary messages varies (TOS: 1 byte,
TTL: 4 bytes), the old implementation failed for TTL on big-endian
hosts.
- Fixed an issue in options processing: TUN and DNS flags had failed on
big-endian systems and the NO- forms had probable never worked.
porting:
- Type conflict between int and sig_atomic_t between declaration and
definition of diag_immediate_type and diag_immediate_exit broke
compilation on FreeBSD 10.1 with clang. Thanks to Emanuel Haupt for
reporting this bug.
- Socat failed to compile on platforms with OpenSSL without
DTLSv1_client_method or DTLSv1_server_method.
Thanks to Simon Matter for sending a patch.
- NuttX OS headers do not provide struct ip, thus socat did not compile.
Made struct ip subject to configure.
Thanks to SP for reporting this issue.
- Socat failed to compile with OpenSSL version 1.0.2d where
SSLv3_server_method and SSLv3_client_method are no longer defined.
Thanks to Mischa ter Smitten for reporting this issue and providing
a patch.
- configure checked for OpenSSL EC_KEY assuming it is a define but it
is a type, thus OpenSSL ECDHE ciphers failed even on Linux.
Thanks to Andrey Arapov for reporting this bug.
- Changes to make socat compile with OpenSSL 1.1.
Thanks to Sebastian Andrzej Siewior e.a. from the Debian team for
providing the base patch.

requirements. Thanks to Garrick Trowsdale for providing a patch
- LibreSSL support: check for OPENSSL_NO_COMP
Thanks to Bernard Spil for providing a patch
testing:
- socks4echo.sh and socks4a-echo.sh hung with new bash with read -n
- test.sh: stderr; option -v (verbose); FDOUT_ERROR description
- improved proxy.sh - it now also takes hostnames
- A few corrections in test.sh
- DTLS1 test hangs on some distributions. Test is now only performed
with OpenSSL 1.0.2 or higher.
- More corrections to test.sh that reveal a mistake with IPV6_TCLASS
docu:
- Corrected source of socat man page to correctly show man references
like socket(2); removed obseolete entries from See Also
- Docu and some comments mentioned addresses SSL-LISTEN and SSL-CONNECT
that do not exist (OPENSSL-LISTEN, SSL-L; and OPENNSSL-CONNECT, SSL
are correct).
Thanks to Zhigang Wang for reporting this issue.
- Fixed a couple of English spelling and grammar mistakes.
Thanks to Jakub Wild for sending the patches.
- NOEXPAND() was not resolved 2 times.
- More minor docu corrections
legal:

####################### V 1.7.3.1:
security:
Socat security advisory 8
A stack overflow in vulnerability was found that can be triggered when
command line arguments (complete address specifications, host names,
file names) are longer than 512 bytes.
Successful exploitation might allow an attacker to execute arbitrary
code with the privileges of the socat process.
This vulnerability can only be exploited when an attacker is able to
inject data into socat's command line.
A vulnerable scenario would be a CGI script that reads data from clients
and uses (parts of) this data as hostname for a Socat invocation.
Test: NESTEDOVFL
Credits to Takumi Akiyama for finding and reporting this issue.
Socat security advisory 7
MSVR-1499
In the OpenSSL address implementation the hard coded 1024 bit DH p
parameter was not prime. The effective cryptographic strength of a key
exchange using these parameters was weaker than the one one could get by
using a prime p. Moreover, since there is no indication of how these
parameters were chosen, the existence of a trapdoor that makes possible
for an eavesdropper to recover the shared secret from a key exchange
that uses them cannot be ruled out.
Futhermore, 1024bit is not considered sufficiently secure.
Fix: generated a new 2048bit prime.
Thanks to Santiago Zanella-Beguelin and Microsoft Vulnerability
Research (MSVR) for finding and reporting this issue.

####################### V 1.7.3.0:
security:
(CVE Id pending)
Fixed problems with signal handling caused by use of not async signal
safe functions in signal handlers that could freeze socat, allowing
denial of service attacks.
Many changes in signal handling and the diagnostic messages system were
applied to make the code async signal safe but still provide detailled
logging from signal handlers:
Coded function vsnprintf_r() as async signal safe incomplete substitute
of libc vsnprintf()
Coded function snprinterr() to replace %m in strings with a system error
message
Instead of gettimeofday() use clock_gettime() when available
Pass Diagnostic messages from signal handler per unix socket to the main
program flow
Use sigaction() instead of signal() for better control
Turn off nested signal handler invocations
Thanks to Peter Lobsinger for reporting and explaining this issue.
Red Hat issue 1019975: add TLS host name checks
OpenSSL client checks if the server certificates names in
extensions/subjectAltName/DNS or in subject/commonName match the name
used to connect or the value of the openssl-commonname option.
Test: OPENSSL_CN_CLIENT_SECURITY
OpenSSL server checks if the client certificates names in
extensions/subjectAltNames/DNS or subject/commonName match the value of
the openssl-commonname option when it is used.
Test: OPENSSL_CN_SERVER_SECURITY
Red Hat issue 1019964: socat now uses the system certificate store with
OPENSSL when neither options cafile nor capath are used
Red Hat issue 1019972: needs to specify OpenSSL cipher suites
Default cipherlist is now "HIGH:-NULL:-PSK:-aNULL" instead of empty to
prevent downgrade attacks
new features:
OpenSSL addresses set couple of environment variables from values in
peer certificate, e.g.:
SOCAT_OPENSSL_X509_SUBJECT, SOCAT_OPENSSL_X509_ISSUER,
SOCAT_OPENSSL_X509_COMMONNAME,
SOCAT_OPENSSL_X509V3_SUBJECTALTNAME_DNS
Tests: ENV_OPENSSL_{CLIENT,SERVER}_X509_*
Added support for methods TLSv1, TLSv1.1, TLSv1.2, and DTLS1
Tests: OPENSSL_METHOD_*
Enabled OpenSSL server side use of ECDHE ciphers. Feature suggested
by Andrey Arapov.
Added a new option termios-rawer for ptys.
Thanks to Christian Vogelgsang for pointing me to this requirement
corrections:
Bind with ABSTRACT commands used non-abstract namespace (Linux).
Test: ABSTRACT_BIND
Thanks to Denis Shatov for reporting this bug.
Fixed return value of nestlex()
Option ignoreeof on the right address hung.
Test: IGNOREEOF_REV
Thanks to Franz Fasching for reporting this bug.
Address SYSTEM, when terminating, shut down its parent addresses,
e.g. an SSL connection which the parent assumed to still be active.
Test: SYSTEM_SHUTDOWN
Passive (listening or receiving) addresses with empty port field bound
to a random port instead of terminating with error.
Test: TCP4_NOPORT
configure with some combination of disable options produced config
files that failed to compile due to missing IPPROTO_TCP.
Thanks to Thierry Fournier for report and patch.
fixed a few minor bugs with OpenSSL in configure and with messages
Socat did not work in FIPS mode because 1024 instead of 512 bit DH prime
is required. Thanks to Zhigang Wang for reporting and sending a patch.
Christophe Leroy provided a patch that fixes memory leaks reported by
valgrind
Help for filan -L was bad, is now corrected to:
"follow symbolic links instead of showing their properties"
Address options fdin and fdout were silently ignored when not applicable
due to -u or -U option. Now these combinations are caught as errors.
Test: FDOUT_ERROR
Issue reported by Hendrik.
Added option termios-cfmakeraw that calls cfmakeraw() and is preferred
over option raw which is now obsolote. On SysV systems this call is
simulated by appropriate setting.
Thanks to Youfu Zhang for reporting issue with option raw.
porting:
Socat included <sys/poll.h> instead of POSIX <poll.h>
Thanks to John Spencer for reporting this issue.
Version 1.7.2.4 changed the check for gcc in configure.ac; this
broke cross compiling. The particular check gets reverted.
Thanks to Ross Burton and Danomi Manchego for reporting this issue.
Debian Bug#764251: Set the build timestamp to a deterministic time:
support external BUILD_DATE env var to allow to build reproducable
binaries
Joachim Fenkes provided an new adapted spec file.
Type bool and macros Min and Max are defined by socat which led to
compile errors when they were already provided by build framework.
Thanks to Liyu Liu for providing a patch.

_POSIX_PTHREAD_SEMANTICS; and minor changes
Red Hat issue 1182005: socat 1.7.2.4 build failure missing
linux/errqueue.h
Socat failed to compile on on PPC due to new requirements for
including <linux/errqueue.h> and a weakness in the conditional code.
Thanks to Michel Normand for reporting this issue.
doc:
In the man page the PTY example was badly formatted. Thanks to
J.F.Sebastian for sending a patch.
Added missing CVE ids to security issues in CHANGES
testing:
Do not distribute testcert.conf with socat source but generate it
(and new testcert6.conf) during test.sh run.
####################### V 1.7.2.4:
corrections:
LISTEN based addresses applied some address options, e.g. so-keepalive,
to the listening file descriptor instead of the connected file
descriptor
Thanks to Ulises Alonso for reporting this bug
make failed after configure with non gcc compiler due to missing
include. Thanks to Horacio Mijail for reporting this problem
configure checked for --disable-rawsocket but printed
--disable-genericsocket in the help text. Thanks to Ben Gardiner for
reporting and patching this bug
In xioshutdown() a wrong branch was chosen after RECVFROM type addresses.
Probably no impact.
Thanks to David Binderman for reproting this issue.
procan could not cleanly format ulimit values longer than 16 decimal
digits. Thanks to Frank Dana for providing a patch that increases field
width to 24 digits.
OPENSSL-CONNECT with bind option failed on some systems, eg.FreeBSD, with
"Invalid argument"
Thanks to Emile den Tex for reporting this bug.
Changed some variable definitions to make gcc -O2 aliasing checker happy

patches/patch-aa seems to have been committed upstream. Passing readline
location to configure and fixing CCOPTS in Makefile.in seems to not be
necessary anymore. From CHANGES:
####################### V 1.7.2.4:
corrections:
LISTEN based addresses applied some address options, e.g. so-keepalive,
to the listening file descriptor instead of the connected file
descriptor
make failed after configure with non gcc compiler due to missing
include.
configure checked for --disable-rawsocket but printed
--disable-genericsocket in the help text.
In xioshutdown() a wrong branch was chosen after RECVFROM type addresses.
Probably no impact.
procan could not cleanly format ulimit values longer than 16 decimal
digits. Thanks to Frank Dana for providing a patch that increases field
width to 24 digits.
OPENSSL-CONNECT with bind option failed on some systems, eg.FreeBSD, with
"Invalid argument"
Changed some variable definitions to make gcc -O2 aliasing checker happy
On big endian platforms with type long >32bit the range option applied a
bad base address.

USE_GNU_READLINE are removed,
* .include "../../devel/readline/buildlink3.mk" without USE_GNU_READLINE
are replaced with .include "../../mk/readline.buildlink3.mk".

The right fix is to thwap socat over the head for worrying about the
values of these constants at compile-time, but that's inexpedient...
ok agc

Security update:
"A heap based buffer overflow vulnerability has been found with data that happens to be output on the READLINE address." (CVE-2012-0219)
Tested according to the official advisory at http://www.dest-unreach.org/socat/contrib/socat-secadv3.html
XXX pull-up to 2013Q1

Changelog:
security:
fixed a stack overflow vulnerability that occurred when command
line arguments (whole addresses, host names, file names) were longer
than 512 bytes.
Note that this could only be exploited when an attacker was able to
inject data into socat's command line.
Full credits to Felix Grobert, Google Security Team, for finding and
reporting this issue

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
* range option supports form address:mask with IPv4
* changed behaviour of SSL-LISTEN to require and verify client
certificate per default
* filan (and socat -D) could hang when a socket was involved
See: http://www.dest-unreach.org/socat/doc/CHANGES for all the details
