SSLsplit develop

• Generically support STARTTLS through the new autossl proxyspec type that upgrades a TCP connection to SSL/TLS when a ClientHello message is seen (based on contribution by @RichardPoole42, pull req #87).
• Fix a rare segmentation fault upon receiving EOF on the inbound connection while the outbound connection has not been established yet (patch by @eunsoopark, issue #124).
• Enable full-strength DHE and ECDHE by default, even for non-RSA leaf keys, in order to avoid weak cipher warnings from browsers (issue #119).
• Fix SSL sessions to actually time out (patch by @eunsoopark, issue #115).
• Add XNU headers for OS X 10.11 El Capitan (issue #116).
• Fix EV_READ event re-enable bug that could lead to stalled connections after throttling one direction (issue #109).
• Add contributed -L log parsing scripts to extra/, including conversion to PCAP using emulated IP and TCP headers (contributed by @mak, issue #27).
• Only initialize DNS subsystems when DNS lookups are actually needed by the loaded proxy specifications (related to issue #104).
• Fix build with LibreSSL that lacks recent OpenSSL API additions.
• Fix build with OpenSSL versions that had SSLv3 support removed.
• Warn when an OpenSSL version mismatch is detected (issue #88).
• Added separate src/dst host and port format specifiers %S, %p, %D and %q to -F (pull req #74 by @AdamJacobMuller).
• Filenames generated by -S and -F %d and %s changed from [host]:port to host,port format and using underscore instead of colon in IPv6 addresses in order to be NTFS clean (issue #69).
• Connect log format: host and port are now separate fields (issues #69 #74).
• Removed the non-standard word "unmodified" from the 2-clause BSD license.
• Add options -w and -W to write generated leaf key, original and forged certificates to disk (issue #67 by @psychomario).
• Add signal SIGUSR1 to re-open long-living -l/-L log files (issue #52).
• Introduce privilege separation architecture with privileged parent process and unprivileged child process; all files are now opened with the privileges of the user running SSLsplit; arguments to -S/-F are no longer relative to the chroot() if used with the -j option.
• Use the same hash algorithm in signatures on forged certificates as the original certificates use, instead of always using SHA-1.
• Removed all references to SHA-1 and small key RSA root CA keys from documentation, examples and unit testing (issue #83).
• Fix passthrough mode with -t and an empty directory (issue #92).
• Minor bugfixes and improvements.

SSLsplit 0.4.11 2015-03-16

• Fix loading of certificate chains with OpenSSL 1.0.2 (issue #79).
• Fix build on Mac OS X 10.10.2 by improving XNU header selection.

SSLsplit 0.4.10 2014-11-28

• Add option -F to log to separate files with printf-style % directives, including process information for connections originating on the same system when also using -i (pull reqs #36, #53, #54, #55 by @landonf).
• Add option -i to look up local process owning a connection for logging to connection log; initial support on Mac OS X (by @landonf) and FreeBSD.
• Add option -r to force a specific SSL/TLS protocol version (issue #30).
• Add option -R to disable specific SSL/TLS protocol versions (issue #30).
• Disallow -u with pf proxyspecs on Mac OS X because Apple restricts ioctl(/dev/pf) to root even on an fd initially opened by root (issue #65).
• Extend the certificate loading workaround for OpenSSL 1.0.0k and 1.0.1e also to OpenSSL 0.9.8y; fixes cert loading crash due to bug in in OpenSSL.
• Extend Mac OS X pf support to Yosemite 10.10.1.
• Fix startup memory leaks in key/cert loader (pull req #56 by @wjjensen).
• Replace WANT_SSLV2_CLIENT and WANT_SSLV2_SERVER build knobs with a single WITH_SSLV2 build knob.
• Minor bugfixes and improvements.

SSLsplit 0.4.9 2014-11-03

• Filter out HSTS response header to allow users to accept untrusted certs.
• Build without SSLv2 support by default (issue #26).
• Add primary group override (-m) when dropping privileges to an unprivileged user (pull req #35 by @landonf).
• Support pf on Mac OS X 10.10 Yosemite and fix segmentation fault if no NAT engine is available (pull req #32 by @landonf).
• Support DESTDIR and MANDIR in the build (pull req #34 by @swills).
• No longer chroot() to /var/empty by default if run by root, in order to prevent breaking -S and sni proxyspecs (issue #21).
• Load -t certificates before dropping privileges (issues #19 and #20).
• Fix segmentation fault when using -t without a CA.
• Minor bugfixes and improvements.

SSLsplit 0.4.8 2014-01-15

• Filter out Alternate-Protocol response header to suppress SPDY/QUIC.
• Add experimental support for pf on Mac OS X 10.7+ (issue #15).
• Also build ipfw NAT engine if pf is detected to support pf divert-to.
• Unit tests (make test) no longer require Internet connectivity.
• Always use SSL_MODE_RELEASE_BUFFERS when available, which lowers the per connection memory footprint significantly when using OpenSSL 1.0.0+.
• Fix memory corruption after the certificate in the cache had to be updated during connection setup (issue #16).
• Fix file descriptor leak in passthrough mode (-P) after SSL errors.
• Fix OpenSSL data structures memory leak on certificate forgery.
• Fix segmentation fault on connections without SNI hostname, caused by compilers optimizing away a NULL pointer check (issue #14).
• Fix thread manager startup failure under some circumstances (issue #17).
• Fix segmentation faults if thread manager fails to start (issue #10).

SSLsplit 0.4.7 2013-07-02

• Fix remaining threading issues in daemon mode.
• Filter HPKP header lines from HTTP(S) response headers in order to prevent public key pinning based on draft-ietf-websec-key-pinning-06.
• Add HTTP status code and content-length to connection log.

SSLsplit 0.4.6 2013-06-03

• Fix fallback to passthrough (-P) when no matching certificate is found for a connection (issue #9).
• Work around segmentation fault when loading certificates caused by a bug in OpenSSL 1.0.0k and 1.0.1e.
• Fix binding to ports < 1024 with default settings (issue #8).

SSLsplit 0.4.5 2012-11-07

• Fix build on recent glibc systems (issue #2).
• Minor code and build process improvements.

• Default elliptic curve is now 'secp160r2' for better ECDH performance.
• More user-friendly handling of -c, -k and friends.
• Unit test source code renamed from *.t to *.t.c to prevent them from being misdetected as perl instead of c by Github et al.
• Minor bugfixes.
