- New upstream release 1.993
- Major rewrite of documentation, now in separate file
- Rework error handling to distinguish between SSL errors and internal errors
(like missing capabilities)
- Fix handling of default_ca if given during the run of the program
(Debian #750646)
- util/analyze-ssl.pl - fix hostname check if SNI does not work
- New upstream release 1.992
- Set $! to undef before doing IO (accept, read...); on Windows a connection
reset could cause an SSL read error without setting $!, so make sure we
don't keep the old value and maybe thus run into an endless loop
- New upstream release 1.991
- New option SSL_OCSP_TRY_STAPLE to enforce staple request even if
VERIFY_NONE
- Work around for CPAN RT#96013 in peer_certificates
- New upstream release 1.990
- Added option SSL_ocsp_staple_callback to get the stapled OCSP response and
verify it somewhere else
- Try to fix warnings on Windows again (CPAN RT#95967)
- Work around temporary OCSP error in t/external/ocsp.t
- New upstream release 1.988
- Allow IPv4 in common name, because browsers allow this too; only for scheme
www/http though, not for rfc2818 (because RC2818 does not allow this; in
default scheme IPv6 and IPv4 are allowed in CN)
- Fix handling of public suffix; add exemption for *.googleapis.com
wildcard, which should not be allowed according to public suffix list but
actually is used
- Add hostname verification test based on older test of chromium, but change
some of the test expectations because we don't want to support IP as SAN
DNS and because we enforce a public suffix list (and thus *.co.uk should
not be allowed)
- Fix t/verify_hostname_standalone.t on systems without usable IDNA or IPv6
(CPAN RT#95719)
- Enable IPv6 support only if we have a usable inet_pton
- Remove stale entries from MANIFEST
- Add transparent support for DER and PKCS#12 files to specify cert and key,
e.g. it will autodetect the format
- If SSL_cert_file is PEM and no SSL_key_file is given it will check if the
key is in SSL_cert_file too
- New upstream release 1.985
- Make OCSP callback return 1 even if it was called on the server side
because of bad setup of the socket; otherwise we get an endless calling of
the OCSP callback
- Consider an OCSP response that is not yet or no longer valid a soft error
instead of an hard error
- Fix skip in t/external/ocsp.t in case fingerprint does not match
- Call EVP_PKEY_free not EVP_KEY_free in IO::Socket::SSL::Utils::KEY_free
(CPAN RT#95633)
- util/analyze.pl - with --show-chain check if chain with SNI is different
from chain w/o SNI
- Drop ExtUtils::MakeMaker version requirement
- New upstream release 1.984
- Added OCSP support:
- Needs Net::SSLeay ≥ 1.59
- For usage see documentation of IO::Socket::SSL (examples and anything
with OCSP in the name)
- New tool util/analyze-ssl.pl, which is intended to help in debugging of SSL
problems and to get information about capabilities of server; it works also
as an example of how to use various features (like OCSP, SNI...)
- Fix peer_certificates (returns leaf certificate only once on client side)
- Added timeout for stop_SSL (either with Timeout or with the default timeout
for IO::Socket)
- Fix IO::Socket::SSL::Utils mapping between ASN1_TIME and time_t when local
time is not GMT; use Net::SSLeay::ASN1_TIME_timet if available
- Fix t/external/usable_ca.t for system with junk in CA files
- New upstream release 1.983
- Fix public suffix handling: ajax.googleapis.com should be ok even if
googleapis.com is in public suffix list (e.g. check one level less)
(CPAN RT#95317)
- usable_ca.t - update fingerprints after heartbleed attack
- usable_ca.t - make sure we have usable CA for tested hosts in CA store
- New upstream release 1.981
- Fix ecdhe test for openssl 1.0.1d (CPAN RT#95432)
- Fix detection of openssl 1.0.1d (detected 1.0.1e instead)
- New function can_ecdh in IO::Socket::SSL
- New upstream release 1.980
- Disable elliptic curve support for openssl 1.0.1d on 64-bit
(http://rt.openssl.org/Ticket/Display.html?id=2975)
- Fix fingerprint calculation
- Add patch to skip elliptic curve test for openssl 1.0.1d on 64-bit
- Add patch to fix openssl version test
- New upstream release 1.979
- Hostname checking:
- Configuration of 'leftmost' is renamed to 'full_label', but the old
version is kept for compatibility reasons
- Documentation of predefined schemes fixed to match reality
- New upstream release 1.978
- Added public prefix checking to verification of wildcard certificates, e.g.
accept *.foo.com but not *.co.uk; see documentation of
SSL_verifycn_publicsuffix and IO::Socket::SSL::PublicSuffix
- Fix publicsuffix for IDNA, more tests with various IDNA libs
(CPAN RT#94424)
- Reuse result of IDN lib detection from PublicSuffix.pm in SSL.pm
- Add more checks to external/usable_ca.t; now it is enough that at least one
of the hosts verifies against the built-in CA store
- Add openssl and Net::SSLeay version to diagnostics in load test
- Switch preferred IDN back-end from Net::LibIDN to URI::_idna as per upstream,
falling back to Net::IDN::Encode on older distributions
- Add fix from upstream git to support building with Test::More < 0.88
- New upstream release 1.975
- BEHAVIOR CHANGE: work around TEA misfeature on OS X built-in openssl, e.g.
guarantee that only the explicitly-given CA or the openssl default CA will
be used; this means that certificates inside the OS X keyring will no
longer be used, because there is no way to control the use by openssl
(e.g. certificate pinning etc.)
- Make external tests run by default to make sure default CA works on all
platforms; it skips automatically on network problems like timeouts or SSL
interception, and can also use http(s)_proxy environment variables
- New upstream release 1.974
- New function peer_certificates to get the whole certificate chain; needs
Net::SSLeay ≥ 1.58
- Extended IO::Socket::Utils::CERT_asHash to provide way more information,
like issuer information, cert and pubkey digests, all extensions, CRL
distribution points and OCSP uri
- New upstream release 1.973
- With SSL_ca, certificate handles can now be used in addition to
SSL_ca_file and SSL_ca_path
- No longer complain if SSL_ca_file and SSL_ca_path are both given;
instead, add both as options to the CA store
- Shortcut 'issuer' to give both issuer_cert and issuer_key in CERT_create
- New upstream release 1.971
- Try to use SSL_hostname for hostname verification if no SSL_verifycn_name
is given; this way, hostname for SNI and verification can be specified in
one step
- New test program example/simulate_proxy.pl
- New upstream release 1.969
- Fix set_defaults to match documentation regarding short names
- New function set_args_filter_hack to make it possible to override bad SSL
settings from other code at the last moment
- Determine default_ca on module load (and not on first use in each thread)
- Don't try default hostname verification if verify_mode 0
- Fix hostname verification when reusing context
- New upstream release 1.968
- BEHAVIOR CHANGE: removed implicit defaults of certs/server-{cert,key}.pem
for SSL_{cert,key}_file and ca/,certs/my-ca.pem for SSL_ca_file; these
defaults were deprecated since 1.951 (July 2013)
- Usable CA verification path on Windows etc.:
- Do not use Net::SSLeay::CTX_set_default_verify_paths any longer to set
system/build dependent default verification path, because there was no
way to retrieve these default values and check if they contained usable
CA
- Instead, re-implement the same algorithm and export the results with
public function default_ca() and make it possible to overwrite it
- Also check for usable verification path during build; if no usable path
is detected, require Mozilla::CA at build and try to use it at runtime
- New upstream release 1.967
- Verify the hostname inside a certificate by default with a superset of
common verification schemes instead of not verifying identity at all; for
now it will only complain if name verification failed but in the future it
will fail certificate verification, forcing you to set the expected
SSL_verifycn_name if you want to accept the certificate
- New option SSL_fingerprint and new methods get_fingerprint and
get_fingerprint_bin; together they can be used to selectively accept
specific certificates that would otherwise fail verification, like
self-signed, outdated or from unknown CAs
- Utils:
- Default RSA key length 2048
- Digest algorithm to sign certificate in CERT_create can be given;
defaults to SHA-256
- CERT_create can now issue non-CA self-signed certificate
- CERT_create add some more useful constraints to certificate
- Spelling fixes
- New upstream release 1.966
- Fixed bug introduced in 1.964 - disabling TLSv1_2 no longer worked by
specifying !TLSv12; only !TLSv1_2 worked
- Fixed leak of session objects in SessionCache, if another session
replaced an existing session (introduced in 1.965)
- New upstream release 1.965
- New key SSL_session_key to influence how sessions are inserted and looked
up in the client's session cache, which makes it possible to share sessions
over different ip:host (as is required with some FTPS servers)
- t/core.t - handle case where default loopback source is not 127.0.0.1, like
in FreeBSD jails
- New upstream release 1.964
- Disabling TLSv1_1 did not work, because the constant was wrong; now it gets
the constants from calling Net::SSLeay::SSL_OP_NO_TLSv1_1 etc.
- The new syntax for the protocols is TLSv1_1 instead of TLSv11, which matches
the syntax from OpenSSL (the old syntax continues to work in SSL_version)
- New functions get_sslversion and get_sslversion_int, which get the SSL
version of the established session as string or int
- Disable t/io-socket-inet6.t if Acme::Override::INET is installed
- New upstream release 1.963
- Fix behavior of stop_SSL: for blocking sockets it now enough to call it
once, for non-blocking it should be called again as long as EAGAIN and
SSL_ERROR is set to SSL_WANT_(READ|WRITE)
- Don't call blocking if start_SSL failed and downgraded socket has no
blocking method
- Documentation enhancements:
- Special section for differences to IO::Socket
- Describe problem with blocking accept on non-blocking socket
- Describe arguments to new_from_fd and make clear that for upgrading an
existing IO::Socket, start_SSL should be used directly
- New upstream release 1.962
- Work around problems with older F5 BIG-IP by offering fewer ciphers on the
client side by default, so that the client hello stays below 255 bytes
- New upstream release 1.960
- Only documentation enhancements:
- Clarify with text and example code, that within event loops not only
select/poll should be used, but also pending has to be called
- Better introduction into SSL; at least mention anonymous authentication as
something you don't want and should take care with the right cipher
- Make it more clear that it's better not to change the cipher list unless
you really know what you're doing
- Adopt upstream's versioning scheme
- New upstream release 1.958
Lots of behavior changes for more secure defaults:
- BEHAVIOR CHANGE: make default cipher list more secure, especially:
- No longer support MD5 by default (broken)
- No longer support anonymous authentication by default (vulnerable to
man in the middle attacks)
- Prefer ECDHE/DHE ciphers and add necessary ECDH curve and DH keys, so
that it uses by default forward secrecy, if underlying
Net::SSLeay/openssl supports it
- Move RC4 to the end, i.e. 3DES is preferred (BEAST attack should
hopefully have been fixed and now RC4 is considered less safe than 3DES)
- Default SSL_honor_cipher_order to 1, e.g. when used as server it tries
to get the best cipher even if the client prefers other ciphers; PLEASE
NOTE that this might break connections with older, less secure
implementations, in which case revert to 'ALL:!LOW:!EXP:!aNULL' or so
- BEHAVIOR CHANGE: SSL_cipher_list now gets set on context, not SSL object,
and thus gets reused if context gets reused; PLEASE NOTE that using
SSL_cipher_list together with SSL_reuse_ctx no longer has any effect on
the ciphers of the context
- Rework hostname verification schemes:
- Add RFC names as scheme (e.g. 'rfc2818', ...)
- Add SIP, SNMP, syslog, netconf, GIST
- BEHAVIOR CHANGE: fix SMTP - now accept wildcards in CN and subjectAltName
- BEHAVIOR CHANGE: fix IMAP, POP3, ACAP, NNTP - now accept wildcards in CN
- BEHAVIOR CHANGE: anywhere wildcards like www* now match only 'www1',
'www2' etc. but not 'www'
- Anywhere wildcards like x* are no longer applied to IDNA names (which start
with 'xn--')
- Fix crash of Utils::CERT_free
- Support TLSv11, TLSv12 as handshake protocols
- Fixed t/core.t: test used cipher_list of HIGH, which includes anonymous
authorization; with the DH param given by default since 1.956, old versions
of openssl (like 0.9.8k) used cipher ADH-AES256-SHA (e.g. anonymous
authorization) instead of AES256-SHA and thus the check for the peer
certificate failed (because ADH does not exchange certificates) - fixed by
explicitly specifying HIGH:!aNULL as cipher (CPAN RT#90221)
- Cleaned up tests:
- Remove ssl_settings.req and 02settings.t, because all tests now create a
simple socket at 127.0.0.1 and thus global settings are no longer needed
- Some tests did not have use strict(!); fixed it
- Removed special handling for older Net::SSLeay versions that are less
than our minimum requirement
- Some syntax enhancements: removed some SSL_version and SSL_cipher_list
options where they were not really needed
- Cleanup: remove workaround for old IO::Socket::INET6 but instead require at
least version 2.55 which is now 5 years old
- Fix t/session.t to work with older openssl versions (CPAN RT#90240)
- New upstream release 1.951
(1.950)
- MAJOR BEHAVIOR CHANGE:
- ssl_verify_mode now defaults to verify_peer for client
- Previously it used verify_none, but loudly complained since 1.79 about it
- It will not complain any longer, but the connection will probably fail
- Please don't simply disable ssl verification; instead, set SSL_ca_file
etc. so that verification succeeds!
- MAJOR BEHAVIOR CHANGE:
- It will now complain if the built-in defaults of certs/my-ca.pem or ca/
for CA and certs/{server,client}-{key,cert}.pem for cert and key are
used, i.e. no certificates are specified explicitly
- In the future these insecure (relative path!) defaults will be removed
and the CA replaced with the system defaults
(1.951)
- Use Net::SSLeay::SSL_CTX_set_default_verify_paths to use openssl's built-in
defaults for CA unless CA path/file was given (or IO::Socket::SSL built-ins
used)
- New upstream release 1.94
- Makefile.PL reported wrong version of openssl if Net::SSLeay was not
installed, instead of reporting a missing dependency of Net::SSLeay
- New upstream release 1.93
- Need at least OpenSSL version 0.9.8 now, since last 0.9.7 was released 6
years ago; remove code to work around older releases
- Changed AUTHOR in Makefile.PL from array back to string, because the array
feature is not available in MakeMaker shipped with 5.8.9 (CPAN RT#85739)
- Set openssl version requirement to 0.9.8
- Drop ExtUtils::MakeMaker version requirement back to 6.46
- New upstream release 1.92
- Intercept: use sha1-fingerprint of original cert for id into cache unless
otherwise given
- Fix pod error in IO::Socket::SSL::Utils (CPAN RT#85733)
- New upstream release 1.91
- Added IO::Socket::SSL::Utils for easier manipulation of certificates and
keys
- Moved SSL interception into IO::Socket::SSL::Intercept and simplified it
using IO::Socket::SSL::Utils
- Enhance meta information in Makefile.PL
- Bump openssl version requirement to 0.9.8a
- Need at least version 6.58 of ExtUtils::MakeMaker (CPAN RT#85739)
- New upstream release 1.90
- Support more digests, especially SHA-2 (CPAN RT#85290)
- Added support for easy SSL interception (man in the middle) based on ideas
found in mojo-mitm proxy
- Make 1.46 the minimal required version for Net::SSLeay, because it
introduced lots of useful functions
- BR:/R: openssl ≥ 0.9.7e for P_ASN1_TIME_(get,set)_isotime in Net::SSLeay
- New upstream release 1.89
- If IO::Socket::IP is used it should be at least version 0.20; otherwise we
get problems with HTTP::Daemon::SSL and maybe others (CPAN RT#81932)
- Spelling corrections
- New upstream release 1.88
- Consider a value of '' the same as undef for SSL_ca_(path|file), SSL_key*
and SSL_cert* - some apps like Net::LDAP use it that way
- New upstream release 1.87
- Complain if given SSL_(key|cert|ca)_(file|path) do not exist or if they are
not readable (CPAN RT#84829)
- Fix use of SSL_key|SSL_file objects instead of files, broken with 1.83
- New upstream release 1.85
- Probe for available modules with local __DIE__ and __WARN__handlers
(CPAN RT#84574)
- Fix warning, when IO::Socket::IP is installed and inet6 support gets explictly
requested (CPAN RT#84619)
- New upstream release 1.84
- Disabled client side SNI for openssl version < 1.0.0 because of
CPAN RT#83289
- Added functions can_client_sni, can_server_sni and can_npn to check
availability of SNI and NPN features
- Added more documentation for SNI and NPN
- New upstream release 1.831
- Separated documention of non-blocking I/O from error handling
- Changed and documented behavior of readline to return the read data on
EAGAIN/EWOULDBLOCK in case of non-blocking socket
(see https://github.com/noxxi/p5-io-socket-ssl/issues/1)
- Bumped release rather than version number to preserve likely upgrade path
and avoid need for epoch or version number ugliness; may revisit this in
light of upstream's future version numbering decisions
- New upstream release 1.83
- Server Name Indication (SNI) support on the server side (CPAN RT#82761)
- Reworked part of the documentation, like providing better examples
- New upstream release 1.82
- sub error sets $SSL_ERROR etc. only if there really is an error; otherwise
it will keep the latest error, which allows IO::Socket::SSL->new to report
the correct problem, even if the problem is deeper in the code (like in
connect)
- Correct spelling (CPAN RT#82790)
- New upstream release 1.81
- Deprecated set_ctx_defaults; new name is set_defaults (the old name is
still available)
- Changed handling of default path for SSL_(ca|cert|key)* keys: if one of
these keys is user defined, don't add defaults for the others, i.e.
don't mix user settings and defaults
- Cleaner handling of module defaults vs. global settings vs. socket
specific settings; global and socket specific settings are both provided
by the user, while module defaults are not
- Make IO::Socket::INET6 and IO::Socket::IP specific tests both run, even
if both modules are installed, by faking a failed load of the other module
- BR: perl(IO::Socket::INET6) and perl(Socket6) unconditionally
- New upstream release 1.79
- Use getnameinfo instead of unpack_sockaddr_in6 to get PeerAddr and PeerPort
from sockaddr in _update_peer, because this provides scope too
- Work around systems that don't define AF_INET6 (CPAN RT#81216)
- Prepare transition to a more secure default for SSL_verify_mode; the use of
the current default SSL_VERIFY_NONE will cause a big warning for clients,
unless SSL_verify_mode was explicitly set inside the application to this
insecure value (in the near future the default will be SSL_VERIFY_PEER, and
thus causing verification failures in unchanged applications)
- New upstream release 1.76
- Add support for IO::Socket::IP, which supports inet6 and inet4
(CPAN RT#75218)
- Fix documentation errors (CPAN RT#77690)
- Made it possible to explicitly disable TLSv11 and TLSv12 in SSL_version
- Use inet_pton from either Socket.pm 1.95 or Socket6.pm
- Use IO::Socket::IP for IPv6 support where available, else IO::Socket::INET6
- Add runtime dependency for appropriate IPv6 support module so that we can
ensure that we run at runtime what we tested with at build time
- New upstream release 1.73
- Set DEFAULT_CIPHER_LIST to ALL:!LOW instead of HIGH:!LOW
- Make test t/dhe.t hopefully work with more versions of openssl
- New upstream release 1.71
- 1.70 done right: don't disable SSLv2 ciphers; SSLv2 support is better
disabled by the default SSL_version of 'SSLv23:!SSLv2'
- New upstream release 1.69 (changes for CPAN RT#76929)
- If no explicit cipher list is given, default to ALL:!LOW instead of the
openssl default, which usually includes weak ciphers like DES
- New config key SSL_honor_cipher_order and document how to use it to fight
BEAST attack
- Fix behavior for empty cipher list (use default)
- Re-added workaround in t/dhe.t
- New upstream release 1.64
- Ignore die from within eval to make tests more stable on Win32
(CPAN RT#76147)
- Clarify some behavior regarding hostname verfication
- Drop patch for t/dhe.t, no longer needed
- New upstream release 1.60
- Don't make blocking readline if socket was set nonblocking, but return as
soon no more data are available (CPAN RT#75910)
- Fix BUG section about threading so that it shows package as thread safe
as long as Net::SSLeay ≥ 1.43 is used (CPAN RT#75749)
- BR: perl(constant), perl(Exporter) and perl(IO::Socket)
- New upstream release 1.59
- If SSLv2 is not supported by Net::SSLeay set SSL_ERROR with useful message
when attempting to use it
- Modify constant declarations so that 5.6.1 should work again
- Drop %defattr, redundant since rpm 4.4
- New upstream release 1.58
- Fix t/dhe.t for openssl 1.0.1 beta by forcing TLSv1, so that it does not
complain about the too small RSA key, which it should not use anyway; this
workaround is not applied for older openssl versions, where it would cause
failures (CPAN RT#75165)
- Add patch to fiddle the openssl version number in the t/dhe.t workaround
because the OPENSSL_VERSION_NUMBER cannot be trusted in Fedora
- One buildreq per line for readability
- Drop redundant buildreq perl(Test::Simple)
- Always run full test suite
- New upstream release 1.56
- Add automatic or explicit (via SSL_hostname) SNI support, needed for
multiple SSL hostnames with the same IP (currently only supported for the
client)
- Use DESTDIR rather than PERL_INSTALL_ROOT
- No need to delete empty directories from buildroot
- New upstream release 1.55:
- Work around IO::Socket's work around for systems returning EISCONN etc. on
connect retry for non-blocking sockets by clearing $! if SUPER::connect
returned true (CPAN RT#75101)
- New upstream release 1.52:
- Fix for t/nonblock.t hangs on AIX (CPAN RT#72305)
- Disable t/memleak_bad_handshake.t on AIX, because it might hang
(CPAN RT#72170)
- Fix syntax error in t/memleak_bad_handshake.t
- New upstream release 1.49:
- Another regression for readline fix: this time it failed to return lines
at EOF that don't end with newline - extended t/readline.t to catch this
case and the fix for 1.48
- New upstream release 1.48:
- Further fix for readline fix in 1.45: if the pending data were false (like
'0'), it failed to read the rest of the line (CPAN RT#71953)
- New upstream release 1.44:
- Fix invalid call to inet_pton in verify_hostname_of_cert when identity
should be verified as ipv6 address because it contains a colon
- New upstream release 1.43:
- Add SSL_create_ctx_callback to have a way to adjust context on creation
(CPAN RT#67799)
- Describe problem of fake memory leak because of big session cache and how
to fix it (CPAN RT#68073)
- Fix t/nonblock.t
- Stability improvements for t/inet6.t
- New upstream release 1.41:
- Fix issue in stop_SSL where it did not issue a shutdown of the SSL
connection if it first received the shutdown from the other side
- Try to make t/nonblock.t more reliable, at least report the real cause of
SSL connection errors
- No longer need to re-code docs to UTF-8
- New upstream release 1.37:
- don't complain about invalid certificate locations if user explicitly set
SSL_ca_path and SSL_ca_file to undef: assume that user knows what they are
doing and will work around the problems themselves (CPAN RT#63741)
- New upstream release 1.35:
- if verify_mode is not VERIFY_NONE and the ca_file/ca_path cannot be
verified as valid, it will no longer fall back to VERIFY_NONE but throw an
error (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=606058)
- New upstream release 1.34:
- schema http for certificate verification changed to wildcards_in_cn=1
- if upgrading socket from inet to ssl fails due to handshake problems, the
socket gets downgraded back again but is still open (CPAN RT#61466)
- deprecate kill_socket: just use close()
verify_hostname_of_cert matched only the prefix for the hostname when no
wildcard was given, e.g. www.example.org matched against a certificate
with name www.exam in it
