Python-GSSAPI provides both low-level and high level wrappers around
the GSSAPI C libraries. While it focuses on the Kerberos mechanism,
it should also be useable with other GSSAPI mechanisms.
Python-GSSAPI is composed of two parts: a low-level C-style API which
thinly wraps the underlying RFC 2744 methods, and a high-level,
Pythonic API (which is itself a wrapper around the low-level API).
Examples may be found in the examples directory.
The low-level API lives in gssapi.raw. The methods contained therein
are designed to match closely with the original GSSAPI C methods. All
relevant methods and classes may be imported directly from gssapi.raw.
Extension methods will only be imported if they are present.
The high-level API lives directly under gssapi. The classes contained
in each file are designed to provide a more Pythonic, Object-Oriented
view of GSSAPI. The exceptions from the low-level API, plus several
additional exceptions, live in gssapi.exceptions. The rest of the
classes may be imported directly from gssapi. Only classes are
exported by gssapi - all functions are methods of classes in the
high-level API.
2.033 2016/07/15
- support for session ticket reuse over multiple contexts and processes
(if supported by Net::SSLeay)
- small optimizations, like saving various Net::SSLeay constants into variables
and access variables instead of calling the constant sub all the time
- make t/dhe.t work with openssl 1.1.0
2.032 2016/07/12
- Set session id context only on the server side. Even if the documentation for
SSL_CTX_set_session_id_context makes clear that this function is server side
only it actually affects hndling of session reuse on the client side too and
can result in error "SSL3_GET_SERVER_HELLO:attempt to reuse session in
different context" at the client.
2.031 2016/07/08
- fix for bug in session handling introduced in 2.031, RT#115975
Thanks to paul[AT]city-fan[DOT]org for reporting
2.030 2016/07/08
- Utils::CERT_create - don't add given extensions again if they were already
added. Firefox croaks with sec_error_extension_value_invalid if (specific?)
extensions are given twice.
- assume that Net::SSLeay::P_PKCS12_load_file will return the CA certificates
with the reverse order as in the PKCS12 file, because that's what it does.
- support for creating ECC keys in Utils once supported by Net::SSLeay
- remove internal sub session_cache and access cache directly (faster)
Patches have been applied upstream.
Release notes:

libssh2 would not return any user authentication methods
* implemented an automatic disconnection when timeouts occur to avoid
dead connections
* fixed crashing bugs in the SFTPClient class handling disconnect events
when an sftp handle was open; the handle must be closed before the
socket connection is closed or a crash will result

methods
* ported the SFTPClient class tests to QUnit and added tests for the
new methods

- PERL5_MODULE_TYPE= Module::Build::Tiny
- Following package added on BUILD_DEPENDS for make test
p5-Moo>=1.001:../../devel/p5-Moo
(upstream)
- Updated security/p5-Data-SimplePassword to 0.11
-----------------------------------------------
0.10 Tue Dec 3 07:10:44 UTC 2013

installation:
* Log the zone before triggering the "part->soamin" assert.
We've seen this fire with older versions, but it's a while
since I saw it happen. This is to provide more debugging info
should it fire.
* If an .ixfr journal file is detected as "corrupted", rename it
to <zone>.ixfr-bad instead of unlinking it, which would leave
no trace of OpenDNSSEC's own wrongdoing.
* If the signer is exposed, avoid a potential DoS vector with a
crafted message.
Bump PKGREVISION.
Noteworthy changes in version 1.7.2 (2016-07-14) [C21/A1/R2]

unusual build errors shown by old gcc versions (works fine for
gcc-5.2.1 on ubuntu and gcc-5.3.0 on NetBSD 7.99.32)
+ use ULL suffix on unsigned 64bit constants, not UL
+ don't typedef the public structs twice - second time just define it
without the typedef
Fixes PR pkg/51327
+ 20160705 introduced a bug whereby a key subid would match and verify
fine, but, if formatted, would not display the correct subkey
information. Fix to show the correct information in this case.
External API changes
====================
+ add a pgpv_cursor_close() function to free resources associated with
a cursor
Better memory management
========================
+ restructure the way dynamic arrays are used, to avoid memory
corruption issues and memory leaks - keep all dynamic arrays in the global
data structure, and use indices in the other data structures to index them.
Means lack of data localisation, but avoids stale pointers, and leaks.
+ make signer field of signature a uint8_t array, rather than a pointer
+ use our own version of strdup(3) - don't depend on it being
available in standard library
+ keep track of whether litdata filenames and userid were allocated or not,
and free memory in pgpv_close() if it was allocated
+ free up allocated resources which were allocated in pgpv_close()
+ get rid of redundant PGPV_ARRAY definition in libverify.c, brought in when
the definitions moved from verify.h
+ fix obuf_add_mem() to use a const void *, as any struct can be
dumped using it
+ remove redundant NO_SUBKEYS definition - unused
+ add an (unused as yet) ARRAY_FREE() macro
+ make the pgpv_t and pgpv_cursor_t structures opaque
+ add new accessor functions for fields in the pgpv_cursor_t struct
+ add new creation functions for the pgpv_t and pgpv_cursor_t structs
2.3.6 - Security fix

OPENSSL_VERSION_NUMBER, see:
https://wiki.openssl.org/index.php/Manual:OPENSSL_VERSION_NUMBER(3)
* Added EVP_aead_chacha20_poly1305_ietf() which matches the AEAD
construction introduced in RFC 7539, which is different than that
already used in TLS with EVP_aead_chacha20_poly1305()
* Avoid a potential undefined C99+ behavior due to shift overflow in
AES_decrypt, reported by Pascal Cuoq <cuoq at trust-in-soft.com>
* More man pages converted from pod to mdoc format
* Added COMODO RSA Certification Authority and QuoVadis
root certificates to cert.pem
* Removed Remove "C=US, O=VeriSign, Inc., OU=Class 3 Public Primary Certification
Authority" (serial 3c:91:31:cb:1f:f6:d0:1b:0e:9a:b8:d0:44:bf:12:be) root
certificate from cert.pem
* Added support for building nc(1) on Solaris
* Fixed GCC 5.x+ preprocessor checks, reported by Ruslan Babayev
* Improved console handling with openssl(1) on Windows

squaring procedure.
- CVE-2015-3196 - Double free race condition of the identify hint
data.
See https://marc.info/?l=openbsd-announce&m=144925068504102
2.3.1 - ASN.1 and time handling cleanups
* ASN.1 cleanups and RFC5280 compliance fixes.
* Time representations switched from 'unsigned long' to 'time_t'. LibreSSL
now checks if the host OS supports 64-bit time_t.
* Fixed a leak in SSL_new in the error path.
* Support always extracting the peer cipher and version with libtls.
* Added ability to check certificate validity times with libtls,
tls_peer_cert_notbefore and tls_peer_cert_notafter.
* Changed tls_connect_servername to use the first address that resolves with
getaddrinfo().
* Remove broken conditional EVP_CHECK_DES_KEY code (non-functional since
initial commit in 2004).
* Fixed a memory leak and out-of-bounds access in OBJ_obj2txt, reported
by Qualys Security.
* Fixed an up-to 7 byte overflow in RC4 when len is not a multiple of
sizeof(RC4_CHUNK), reported by Pascal Cuoq <cuoq at trust-in-soft.com>.
* Reject too small bits value in BN_generate_prime_ex(), so that it does
not risk becoming negative in probable_prime_dh_safe(), reported by
Franck Denis.
* Enable nc(1) builds on more platforms.
2.3.0 - SSLv3 removed, libtls API changes, portability improvements
* SSLv3 is now permanently removed from the tree.
* The libtls API is changed from the 2.2.x series.
The read/write functions work correctly with external event
libraries. See the tls_init man page for examples of using libtls
correctly in asynchronous mode.
Client-side verification is now supported, with the client supplying
the certificate to the server.
Also, when using tls_connect_fds, tls_connect_socket or
tls_accept_fds, libtls no longer implicitly closes the passed in
sockets. The caller is responsible for closing them in this case.
* When loading a DSA key from an raw (without DH parameters) ASN.1
serialization, perform some consistency checks on its `p' and `q'
values, and return an error if the checks failed.
Thanks for Georgi Guninski (guninski at guninski dot com) for
mentioning the possibility of a weak (non prime) q value and
providing a test case.
See
https://cpunks.org/pipermail/cypherpunks/2015-September/009007.html
for a longer discussion.
* Fixed a bug in ECDH_compute_key that can lead to silent truncation
of the result key without error. A coding error could cause software
to use much shorter keys than intended.
* Removed support for DTLS_BAD_VER. Pre-DTLSv1 implementations are no
longer supported.
* The engine command and parameters are removed from the openssl(1).
Previous releases removed dynamic and builtin engine support
already.
* SHA-0 is removed, which was withdrawn shortly after publication 20
years ago.
* Added Certplus CA root certificate to the default cert.pem file.
* New interface OPENSSL_cpu_caps is provided that does not allow
software to inadvertently modify cpu capability flags.
OPENSSL_ia32cap and OPENSSL_ia32cap_loc are removed.
* The out_len argument of AEAD changed from ssize_t to size_t.
* Deduplicated DTLS code, sharing bugfixes and improvements with
TLS.
* Converted 'nc' to use libtls for client and server operations; it is
included in the libressl-portable distribution as an example of how
to use the library.
+ Perform digest on correctly dash-escaped text, per RFC 4880.
Problem pointed out by Dimitri John Ledkov, fixed in a different way
(in case the last line is itself dash-escaped).
+ add test case
+ remove use of asprintf and vasprintf from libverify. Inspired
by work from Dimitri John Ledkov. Should allow building on Linux
without superfluous definitions.
+ also free the BIGNUM struct in PGPV_BN_clear() - from Dimitri
John Ledkov
2.029 2016/07/26

Upstream changelog since 1.3.11 follows.
= mbed TLS 2.2.1 released 2016-01-05
Security
- Fix potential double free when mbedtls_asn1_store_named_data() fails
to allocate memory. Only used for certificate generation, not
triggerable remotely in SSL/TLS.
- Disable MD5 handshake signatures in TLS 1.2 by default
Bugfix
- Fix over-restrictive length limit in GCM.
- Fix bug in certificate validation that caused valid chains to be
rejected when the first intermediate certificate has
pathLenConstraint=0.
- Removed potential leak in mbedtls_rsa_rsassa_pkcs1_v15_sign()
- Fix suboptimal handling of unexpected records that caused interop
issues with some peers over unreliable links. Avoid dropping an
entire DTLS datagram if a single record in a datagram is unexpected,
instead only drop the record and look at subsequent records (if any
are present) in the same datagram.
= mbed TLS 2.2.0 released 2015-11-04
Security
- Fix potential double free if mbedtls_ssl_conf_psk() is called more
than once and some allocation fails. Cannot be forced remotely.
- Fix potential heap corruption on Windows when
mbedtls_x509_crt_parse_path() is passed a path longer than 2GB.
Cannot be triggered remotely.
- Fix potential buffer overflow in some asn1_write_xxx() functions.
Cannot be triggered remotely unless you create X.509 certificates
based on untrusted input or write keys of untrusted origin.
- The X509 max_pathlen constraint was not enforced on intermediate
certificates.
Features
- Experimental support for EC J-PAKE as defined in Thread 1.0.0.
Disabled by default as the specification might still change.
- Added a key extraction callback to accees the master secret and key
block. (Potential uses include EAP-TLS and Thread.)
Bugfix
- Self-signed certificates were not excluded from pathlen counting,
resulting in some valid X.509 being incorrectly rejected.
- Fix build error with configurations where ECDHE-PSK is the only key
exchange.
- Fix build error with configurations where RSA, RSA-PSK, ECDH-RSA or
ECHD-ECDSA if the only key exchange. Multiple reports.
- Fixed a bug causing some handshakes to fail due to some non-fatal
alerts not being properly ignored.
- mbedtls_x509_crt_verify(_with_profile)() now also checks the key
type and size/curve against the profile. Before that, there was no
way to set a minimum key size for end-entity certificates with
RSA keys.
- Fix failures in MPI on Sparc(64) due to use of bad assembly code.
- Fix typo in name of the extKeyUsage OID.
- Fix bug in ASN.1 encoding of booleans that caused generated CA
certificates to be rejected by some applications, including OS X
Keychain.
Changes
- Improved performance of mbedtls_ecp_muladd() when one of the scalars
is or -1.
= mbed TLS 2.1.2 released 2015-10-06
Security
- Added fix for CVE-2015-5291 to prevent heap corruption due to buffer
overflow of the hostname or session ticket.
- Fix potential double-free if mbedtls_ssl_set_hs_psk() is called more
than once in the same handhake and mbedtls_ssl_conf_psk() was used.
- Fix stack buffer overflow in pkcs12 decryption (used by
mbedtls_pk_parse_key(file)() when the password is > 129 bytes.
- Fix potential buffer overflow in mbedtls_mpi_read_string().
- Fix potential random memory allocation in mbedtls_pem_read_buffer()
on crafted PEM input data.
- Fix possible heap buffer overflow in base64_encoded() when the input
buffer is 512MB or larger on 32-bit platforms.
- Fix potential double-free if mbedtls_conf_psk() is called repeatedly
on the same mbedtls_ssl_config object and memory allocation fails.
- Fix potential heap buffer overflow in servers that perform client
authentication against a crafted CA cert. Cannot be triggered
remotely unless you allow third parties to pick trust CAs for
client auth.
Bugfix
- Fix compile error in net.c with musl libc.
- Fix macroization of 'inline' keyword when building as C++.
Changes
- Added checking of hostname length in mbedtls_ssl_set_hostname() to
ensure domain names are compliant with RFC 1035.
- Fixed paths for check_config.h in example config files.
= mbed TLS 2.1.1 released 2015-09-17
Security
- Add countermeasure against Lenstra's RSA-CRT attack for PKCS#1 v1.5
signatures.
- Fix possible client-side NULL pointer dereference (read) when the
client tries to continue the handshake after it failed (a misuse
of the API).
Bugfix
- Fix warning when using a 64bit platform.
- Fix off-by-one error in parsing Supported Point Format extension
that caused some handshakes to fail.
Changes
- Made X509 profile pointer const in mbedtls_ssl_conf_cert_profile()
to allow use of mbedtls_x509_crt_profile_next.
- When a client initiates a reconnect from the same port as a live
connection, if cookie verification is available
(MBEDTLS_SSL_DTLS_HELLO_VERIFY defined in config.h, and usable
cookie callbacks set with mbedtls_ssl_conf_dtls_cookies()), this
will be detected and mbedtls_ssl_read() will return
MBEDTLS_ERR_SSL_CLIENT_RECONNECT - it is then possible to start a
new handshake with the same context. (See RFC 6347 section 4.2.8.)
= mbed TLS 2.1.0 released 2015-09-04

complementing the ability to override the whole module.
- New server-side implementation of session tickets that rotate keys
to preserve forward secrecy, and allows sharing across multiple
contexts.
- Added a concept of X.509 cerificate verification profile that
controls which algorithms and key sizes (curves for ECDSA) are
acceptable.
- Expanded configurability of security parameters in the SSL module
with mbedtls_ssl_conf_dhm_min_bitlen() and mbedtls_ssl_conf_sig_hashes().
- Introduced a concept of presets for SSL security-relevant
configuration parameters.
API Changes
- The library has been split into libmbedcrypto, libmbedx509,
libmbedtls. You now need to link to all of them if you use TLS
for example.
- All public identifiers moved to the mbedtls_* or MBEDTLS_*
namespace. Some names have been further changed to make them more
consistent. Migration helpers scripts/rename.pl and
include/mbedlts/compat-1.3.h are provided. Full list of renamings
in scripts/data_files/rename-1.3-2.0.txt
- Renamings of fields inside structures, not covered by the previous
list:
mbedtls_cipher_info_t.key_length -> key_bitlen
mbedtls_cipher_context_t.key_length -> key_bitlen
mbedtls_ecp_curve_info.size -> bit_size
- Headers are now found in the 'mbedtls' directory (previously
'polarssl').
- The following _init() functions that could return errors have
been split into an _init() that returns void and another function
that should generally be the first function called on this context after
init:
mbedtls_ssl_init() -> mbedtls_ssl_setup()
mbedtls_ccm_init() -> mbedtls_ccm_setkey()
mbedtls_gcm_init() -> mbedtls_gcm_setkey()
mbedtls_hmac_drbg_init() -> mbedtls_hmac_drbg_seed(_buf)()
mbedtls_ctr_drbg_init() -> mbedtls_ctr_drbg_seed()
Note that for mbedtls_ssl_setup(), you need to be done setting up
the ssl_config structure before calling it.
- Most ssl_set_xxx() functions (all except ssl_set_bio(),
ssl_set_hostname(),
ssl_set_session() and ssl_set_client_transport_id(), plus
ssl_legacy_renegotiation()) have been renamed to
mbedtls_ssl_conf_xxx() (see rename.pl and compat-1.3.h above) and
their first argument's type changed from ssl_context to ssl_config.
- ssl_set_bio() changed signature (contexts merged, order switched,
one additional callback for read-with-timeout).
- The following functions have been introduced and must be used in
callback implementations (SNI, PSK) instead of their *conf
counterparts:
mbedtls_ssl_set_hs_own_cert()
mbedtls_ssl_set_hs_ca_chain()
mbedtls_ssl_set_hs_psk()
- mbedtls_ssl_conf_ca_chain() lost its last argument (peer_cn), now
set using mbedtls_ssl_set_hostname().
- mbedtls_ssl_conf_session_cache() changed prototype (only one context
pointer, parameters reordered).
- On server, mbedtls_ssl_conf_session_tickets_cb() must now be used in
place of mbedtls_ssl_conf_session_tickets() to enable session
tickets.
- The SSL debug callback gained two new arguments (file name, line
number).
- Debug modes were removed.
- mbedtls_ssl_conf_truncated_hmac() now returns void.
- mbedtls_memory_buffer_alloc_init() now returns void.
- X.509 verification flags are now an uint32_t. Affect the signature
of:
mbedtls_ssl_get_verify_result()
mbedtls_x509_ctr_verify_info()
mbedtls_x509_crt_verify() (flags, f_vrfy -> needs to be updated)
mbedtls_ssl_conf_verify() (f_vrfy -> needs to be updated)
- The following functions changed prototype to avoid an in-out length
parameter:
mbedtls_base64_encode()
mbedtls_base64_decode()
mbedtls_mpi_write_string()
mbedtls_dhm_calc_secret()
- In the NET module, all "int" and "int *" arguments for file
descriptors changed type to "mbedtls_net_context *".
- net_accept() gained new arguments for the size of the client_ip
buffer.
- In the threading layer, mbedtls_mutex_init() and
mbedtls_mutex_free() now return void.
- ecdsa_write_signature() gained an addtional md_alg argument and
ecdsa_write_signature_det() was deprecated.
- pk_sign() no longer accepts md_alg == POLARSSL_MD_NONE with ECDSA.
- Last argument of x509_crt_check_key_usage() and
mbedtls_x509write_crt_set_key_usage() changed from int to unsigned.
- test_ca_list (from certs.h) is renamed to test_cas_pem and is only
available if POLARSSL_PEM_PARSE_C is defined (it never worked
without).
- Test certificates in certs.c are no longer guaranteed to be
nul-terminated strings; use the new *_len variables instead of strlen().
- Functions mbedtls_x509_xxx_parse(), mbedtls_pk_parse_key(),
mbedtls_pk_parse_public_key() and mbedtls_dhm_parse_dhm() now expect
the length parameter to include the terminating null byte for PEM input.
- Signature of mpi_mul_mpi() changed to make the last argument
unsigned
- calloc() is now used instead of malloc() everywhere. API of platform
layer and the memory_buffer_alloc module changed accordingly.
- Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
(support for renegotiation now needs explicit enabling in config.h).
- Split MBEDTLS_HAVE_TIME into MBEDTLS_HAVE_TIME and
MBEDTLS_HAVE_TIME_DATE in config.h
- net_connect() and net_bind() have a new 'proto' argument to choose
between TCP and UDP, using the macros NET_PROTO_TCP or
NET_PROTO_UDP. Their 'port' argument type is changed to a string.
- Some constness fixes
Removals
- Removed mbedtls_ecp_group_read_string(). Only named groups are
supported.
- Removed mbedtls_ecp_sub() and mbedtls_ecp_add(), use
mbedtls_ecp_muladd().
- Removed individual mdX_hmac, shaX_hmac, mdX_file and shaX_file
functions (use generic functions from md.h)
- Removed mbedtls_timing_msleep(). Use mbedtls_net_usleep() or a
custom waiting function.
- Removed test DHM parameters from the test certs module.
- Removed the PBKDF2 module (use PKCS5).
- Removed POLARSSL_ERROR_STRERROR_BC (use mbedtls_strerror()).
- Removed compat-1.2.h (helper for migrating from 1.2 to 1.3).
- Removed openssl.h (very partial OpenSSL compatibility layer).
- Configuration options POLARSSL_HAVE_LONGLONG was removed (now always
on).
- Configuration options POLARSSL_HAVE_INT8 and POLARSSL_HAVE_INT16
have been removed (compiler is required to support 32-bit operations).
- Configuration option POLARSSL_HAVE_IPV6 was removed (always
enabled).
- Removed test program o_p_test, the script compat.sh does more.
- Removed test program ssl_test, superseded by ssl-opt.sh.
- Removed helper script active-config.pl
New deprecations
- md_init_ctx() is deprecated in favour of md_setup(), that adds a
third argument (allowing memory savings if HMAC is not used)
Semi-API changes (technically public, morally private)
- Renamed a few headers to include _internal in the name. Those
headers are not supposed to be included by users.
- Changed md_info_t into an opaque structure (use md_get_xxx()
accessors).
- Changed pk_info_t into an opaque structure.
- Changed cipher_base_t into an opaque structure.
- Removed sig_oid2 and rename sig_oid1 to sig_oid in x509_crt and
x509_crl.
- x509_crt.key_usage changed from unsigned char to unsigned int.
- Removed r and s from ecdsa_context
- Removed mode from des_context and des3_context
Default behavior changes
- The default minimum TLS version is now TLS 1.0.
- RC4 is now blacklisted by default in the SSL/TLS layer, and excluded
from the default ciphersuite list returned by ssl_list_ciphersuites()
- Support for receiving SSLv2 ClientHello is now disabled by default
at compile time.
- The default authmode for SSL/TLS clients is now REQUIRED.
- Support for RSA_ALT contexts in the PK layer is now optional. Since
is is enabled in the default configuration, this is only noticeable
if using a custom config.h
- Default DHM parameters server-side upgraded from 1024 to 2048 bits.
- A minimum RSA key size of 2048 bits is now enforced during
ceritificate chain verification.
- Negotiation of truncated HMAC is now disabled by default on server
too.
- The following functions are now case-sensitive:
mbedtls_cipher_info_from_string()
mbedtls_ecp_curve_info_from_name()
mbedtls_md_info_from_string()
mbedtls_ssl_ciphersuite_from_string()
mbedtls_version_check_feature()
Requirement changes
- The minimum MSVC version required is now 2010 (better C99 support).
- The NET layer now unconditionnaly relies on getaddrinfo() and
select().
- Compiler is required to support C99 types such as long long and
uint32_t.
API changes from the 1.4 preview branch
- ssl_set_bio_timeout() was removed, split into mbedtls_ssl_set_bio()
with new prototype, and mbedtls_ssl_set_read_timeout().
- The following functions now return void:
mbedtls_ssl_conf_transport()
mbedtls_ssl_conf_max_version()
mbedtls_ssl_conf_min_version()
- DTLS no longer hard-depends on TIMING_C, but uses a callback
interface instead, see mbedtls_ssl_set_timer_cb(), with the Timing
module providing an example implementation, see
mbedtls_timing_delay_context and mbedtls_timing_set/get_delay().
- With UDP sockets, it is no longer necessary to call net_bind() again
after a successful net_accept().
Changes
- mbedtls_ctr_drbg_random() and mbedtls_hmac_drbg_random() are now
thread-safe if MBEDTLS_THREADING_C is enabled.
- Reduced ROM fooprint of SHA-256 and added an option to reduce it
even more (at the expense of performance) MBEDTLS_SHA256_SMALLER.
This is based on security/mbedtls and only meant for compatibility
with software that doesn't support mbedtls>=2 yet (mainly requires
the PolarSSL compatibility layer).

- Install/compile fails of letsencrypt-auto on Smartos/Illumos
+ bring over joerg's printflike change from the netpgpverify
version in src/crypto
+ add a test for cleartext signatures with version information
to complement the one with no version information
Simplify the method of finding the end of the versioning information
in the signature - back up to the "\n" character at the end of the
signature start:
"-----BEGIN PGP SIGNATURE-----\n"
and then find the "\n\n" character sequence to denote the start of the
signature itself. The previous version worked, but this is more efficient.
+ handle signatures created by gpg with "--no-emit-version", don't assume
there will always be a version string.
+ add a test for above
Fixes security PR/51240.

on pkgsrc-users.
Changes from 0.99.1 to 0.99.2 are available only with ChangeLog and it
is too many to write here. Please refer ChangeLog file.
0.99.1
------
ClamAV 0.99.1 contains a new feature for parsing Hancom Office files
including extracting and scanning embedded objects. ClamAV 0.99.1
also contains important bug fixes. Please see ChangeLog for details.
Make a temporary hack for non-SunOS, not yet fully verified;
this somehow needs to mirror what the package's configure.py
figures out, and expressing that properly and portably in
pkgsrc seems hard.
This Python package is a high-level wrapper for Kerberos (GSSAPI)
operations. The goal is to avoid having to build a module that
wraps the entire Kerberos.framework, and instead offer a limited
set of functions that do what is needed for client/server Kerberos
authentication based on RFC 4559.
News:
This release fix targets stability issues which have had a history
and had been hard to reproduce. Stability should be improved,
running OpenDNSSEC as a long term service.
Changes in TTL in the input zone that seem not to be propagated,
notifies to slaves under load that where not handled properly and
could lead to assertions. NSEC3PARAM that would appear duplicate
in the resulting zone, and crashes in the signer daemon in seldom
race conditions or re-opening due to a HSM reset.
No migration steps needed when upgrading from OpenDNSSEC 1.4.9.
Also have a look at our OpenDNSSEC 2.0 beta release, its impending
release will help us forward with new development and signal phasing
out historic releases.
Fixes:
* SUPPORT-156 OPENDNSSEC-771: Multiple NSEC3PARAM records in signed
zone. After a resalt the signer would fail to remove the old
NSEC3PARAM RR until a manual resign or incoming transfer. Old
NSEC3PARAMS are removed when inserting a new record, even if
they look the same.
* OPENDNSSEC-725: Signer did not properly handle new update while
still distributing notifies to slaves. An AXFR disconnect looked
not to be handled gracefully.
* SUPPORT-171: Signer would sometimes hit an assertion using DNS
output adapter when .ixfr was missing or corrupt but .backup file
available. Above two issues also in part addresses problems
with seemingly corrected backup files (SOA serial). Also an
crash on badly configured DNS output adapters is averted.
* The signer daemon will now refuse to start when failed to open
a listen socket for DNS handling.
* OPENDNSSEC-478 OPENDNSSEC-750 OPENDNSSEC-581 OPENDNSSEC-582
SUPPORT-88: Segmentation fault in signer daemon when opening and
closing hsm multiple times. Also addresses other concurrency
access by avoiding a common context to the HSM (a.k.a. NULL
context).
* OPENDNSSEC-798: Improper use of key handles across hsm reopen,
causing keys not to be available after a re-open.
* SUPPORT-186: IXFR disregards TTL changes, when only TTL of an
RR is changed. TTL changes should be treated like any other
changes to records. When OpenDNSSEC now overrides a TTL value,
this is now reported in the log files.
the PLIST.x86* entries. The sse2 entries are however gone, but a few
new ones have appeared (md4_x86_32.h etc.) Installs cleanly now on
NetBSD/i386 6.1.5.
1.1.2 (2016-06-01)
------------------
* (Fix) Query strings should be able to include colons.
* (Fix) Cast body to a string to ensure that we can perform a regex substitution on it.
1.4 - 2016-06-04
~~~~~~~~~~~~~~~~
* Support for OpenSSL 0.9.8 has been removed. Users on older versions of
OpenSSL will need to upgrade.
* Added :class:`~cryptography.hazmat.primitives.kdf.kbkdf.KBKDFHMAC`.
* Added support for ``OpenSSH`` public key serialization.
* Added support for SHA-2 in RSA
:class:`~cryptography.hazmat.primitives.asymmetric.padding.OAEP` when using
OpenSSL 1.0.2 or greater.
* Added "one shot"
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey.sign`
and
:meth:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.verify`
methods to RSA keys.
