* Noteworthy changes in release 4.5 (released 2015-04-29) [stable]
- Corrected an invalid memory access in octet string decoding.
Reported by Hanno Böck.
- Added sanity checks in the decoding of time when
ASN1_DECODE_FLAG_STRICT_DER is used.
- Fixes in the decoding of OCTET STRING when close to the end
of the structure.
- Corrected an off-by-one error in ASN.1 DER tag decoding.
- Several improvements and new safety checks on DER decoding;
issues found using Codenomicon TLS test suite.

- Code improvements
* Noteworthy changes in release 3.1 (released 2012-11-24) [stable]
- Completed rename of types:
ASN1_ARRAY_TYPE -> asn1_static_node (was asn1_static_node_t)
- Added new types: VisibleString, NumericString, IA5String, TeletexString,
PrintableString, UniversalString, BMPString, UTF8String. When re-defined
a warning is being print instead of failing.
- Parser outputs more detailed syntax error messages.
- Added asn1_decode_simple_der() and asn1_encode_simple_der().
- Added asn1_read_value_type() to return value and type.
- Introduced ASN1_ETYPE_UTC_TIME and ASN1_ETYPE_GENERALIZED_TIME
* Noteworthy changes in release 3.0 (2012-10-28) [stable]
- Added tool in tests/ to benchmark X.509 structure decoding.
- Added asn1_read_node_value() to obtain a node's value.
- Optimizations in internal tree allocation.
- Optimizations in tree search.
- libtasn1.h no longer exports internal structures.
- Types were renamed for consistency:
ASN1_DATA_NODE -> asn1_data_node_st
ASN1_ARRAY_TYPE -> asn1_static_node
ASN1_TYPE -> asn1_node
ASN1_TYPE_EMPTY -> NULL
static_struct_asn -> asn1_static_node_st
node_asn_struct -> asn1_node_st
node_asn -> asn1_node_st
(the old types are still available as definitions)
* Noteworthy changes in release 2.14 (2012-09-24) [stable]
- Added asn1_read_node_value() to obtain a node's value.
This is to deprecate the export of the node_asn internal structure
for the upcoming 3.x release. The ASN1_DATA_NODE type and the
ASN1_ETYPE_* constants were added to support the new function.
* Noteworthy changes in release 2.13 (2012-05-31) [stable]
- Updated fix for DER decoding issue to not depend on specific compilers.
- Updated DER decoding check to apply to short form integers as well.
* Noteworthy changes in release 2.12 (2012-03-19) [stable]
- Cleanup license headers.
- build: Update gnulib files.
- Corrected DER decoding issue (reported by Matthew Hall).
Added self check to detect the problem, see tests/Test_overflow.c.
This problem can lead to at least remotely triggered crashes, see
further analysis on the libtasn1 mailing list.
* Noteworthy changes in release 2.11 (2011-11-25) [stable]
- qa: Now builds without compiler warnings with Solaris CC.
- qa: Added clang analysis. Fixed cyclomatic complexity output.
- tests: Added self-test of bit string functions.
- build: Added windows/libtasn14win.mk rules to produce Windows binaries.
- build: Don't hard code path to perl in doc/gdoc.
- Various minor fixes.
* Noteworthy changes in release 2.9 (2010-12-06) [stable]
- tests: Link to gnulib to avoid build error related to 'rpl_ftello' on Solaris.
Reported by Dagobert Michelsen.
- doc: Fix bug reporting address to point at help-libtasn1@gnu.org.
- doc: Fix Returns: documentation in Texinfo. Reported by Jeffrey Walton.
- build: Update gnulib files.
The patch looks wrong to me, though, because stdint.h should be
generated in lib/gllib/ if the system does not have it (or if it is not
correct), and the -I's should make the code find the local file instead.
Thus, the code should be able to unconditionally include the header
file.
* Noteworthy changes in release 2.7 (2010-05-20) [stable]
- Doc: Build a PDF manual using GTK-PDC.
- Doc: Fix of asn1_check_version, documentation was missing from last release.
- Build: Avoid warnings about ignored visibility attributes on Windows.

- tests: Improved self-checks.
- Update gnulib files, fix many syntax-check nits, indent code,
fix license templates.

- Libtasn1 is now an official GNU project.
- Solve build problem on Tru64 related to TRUE/FALSE.
- More careful decoding of OIDs.
- Fixed warning in ASN1.y.

<http://article.gmane.org/gmane.comp.lib.gnulib.bugs/17791> for more
details.
Version 2.2 (released 2009-05-20)
- Change how the ASN1_API decorator is used in libtasn1.h, for GTK-DOC.
- Changed license of libtasn1.pc from GPLv3+ to LGPLv2.1+.
Reported by Jeff Cai <Jeff.Cai@Sun.COM>.
- Building with many warning flags now requires --enable-gcc-warnings.
- Some warnings fixed.
Version 2.1 (released 2009-04-17)
- Fix compilation failure on platforms that can't generate empty archives,
e.g., Mac OS X. Reported by David Reiser <dbreiser@gmail.com>.
Version 2.0 (released 2009-04-13)
- Optimized tree generation.
- ASN1 parser code re-generated using Bison 2.4.1.
- Build with more warning flags. Many compiler warnings fixed.
- Compiled with -fvisibility=hidden by default if supported.
See http://gcc.gnu.org/wiki/Visibility
- The libtasn1-config tool has been removed.
For application developers, please stop using libtasn1-config for
finding libtasn1, use proper autoconf checks or pkg-config instead.
For users that need a libtasn1 that provides a libtasn1-config
script (for use with older applications), use libtasn1 v1.x instead.
Version 1.x is still supported.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
- Add libtasn1-config for compatibility.
Please stop use it as it will disappear in v2.0!
Use standard AC_CHECK_FUNCS autoconf tests or pkg-config instead.
- Read PKCS-12 blob as binary file, fixes self-tests under Mingw.
- Fix use of __attribute__ ((deprecated)) to work on non-GCC.
Changes 1.6:
- Fixed namespace violation for MAX_NAME_SIZE and MAX_ERROR_DESCRIPTION_SIZE.
The new names are ASN1_MAX_NAME_SIZE and ASN1_MAX_ERROR_DESCRIPTION_SIZE.
- Fixed namespace violation for libtasn1_perror and libtasn1_strerror.
The new names are asn1_perror and asn1_strerror.
- Fix namespace violation for LIBASN1_VERSION.
The new name is ASN1_VERSION.
- Decoder can now decode BER encoded octet strings.
- doc: Change license on the manual to GFDLv1.3+.
- doc: Sync gdoc script with GnuTLS, changes license on man-pages to GAP.
- doc: Improve gtk-doc manual.
- Assumes system has strdup and string.h.
- Remove libtasn1-config and libtasn1.m4,
use standard AC_CHECK_FUNCS autoconf tests or pkg-config instead.
- Change detection of when to use a linker version script,
use --enable-ld-version-script or --disable-ld-version-script to
override auto-detection logic.
Version 1.3 (released 2008-02-01)
- Handle 'INTEGER { ... } (a..b)' regression.
Revert parts of earlier fix. asn1Parser can now again parse src/pkix.asn1.
The ASN1.c file was generated using Bison 2.3.
- Move examples from src/ to new directory examples/.
- Duplicate copy of divergated pkix.asn removed.
- Merge unnecessary lib/defines.h into lib/int.h.
- Configure no longer tries to use gcc -pipe.
- Update gnulib files.
- Fix mem leak in self-test.
Version 1.2 (released 2007-12-10)
- Update gnulib files.
Version 1.1 (released 2007-08-31)
- Fix bug that made asn1_check_version believe that 1.0 is older than 0.3.10.
Version 1.0 (released 2007-08-31)
- The self-tests, command line tools and build infrastructure have
been re-licensed from GPLv2 to GPLv3.
- Doc fixes.
- Update gnulib files.
Version 0.3.10 (released 2007-05-25)
- Update gnulib files.
Version 0.3.9 (released 2007-03-02)
- In generated code, config.h is pulled in if HAVE_CONFIG_H.
- Development changes: changed from CVS to GIT as an experiment.
I push my changes to <http://repo.or.cz/w/libtasn1.git>.
- Autoconf 2.61 and automake 1.10 is required.
Version 0.3.8 (released 2006-11-16)
- Fix reading of binary files in asn1Decoding, for Windows.
Version 0.3.7 (released 2006-10-19)
- When asn1_der_coding encoded a TYPE_NULL and the output buffer is
NULL, it would not increment the counter properly, so the size of
the required buffer would be off by one. Fixed. Reported by
Stephen Wrobleski <steve@localtoast.org>.
- Fix configure to respect user-definable flags. Reported by "Diego
'Flameeyes' Pettenò" <flameeyes@gentoo.org>.
- The --help and --version outputs from the tools have been improved.
Version 0.3.6 (released 2006-08-13)
- Fix man pages to use \- instead of - for negative signs (as in "-1").
- Add -I's when building in src/, so that unistd.h etc is found on
systems that doesn't have them.
- Valgrind isn't used for cross-compilation by default, and there is
also --disable-valgrind-tests to unconditionally disable it.
- Valgrind is invoked without parameters, put things you like into
~/.valgrindrc instead.
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
changes:
- Fix asn1_octet_der to handle writes of zero-length buffers, before
it did not write the ASN.1 length for a zero-length buffer. This caused
ASN.1 encodings to be incorrect on 64-bit platforms.
- Add self test that attempt to trigger the above bug.
- Fix test of -Wno-pointer-sign.
- Improve cross-compilation to MinGW by using AC_LIBTOOL_WIN32_DLL.
Version 0.3.4 (released 2006-05-10)
- Really fix encodings.
- Add new self test, tests/Test_encoding.c.
- Self tests are ran under valgrind, if it is available.
- We test for the -Wno-pointer-sign parameter before using it.
Version 0.3.3 (released 2006-05-07)
- Add some 'const' to prototypes.
- Remove some 'unsigned' keywords.
- Corrected asn1_der_coding() bug introduced when it became reentrant.
Now it produces correct encodings.
RECOMMENDED is removed. It becomes ABI_DEPENDS.
BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.
BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.
BUILDLINK_DEPENDS does not change.
IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".
Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
Version 0.3.2
- Corrected bug in asn1_der_coding() which overwrited some
data in the original structure.
- The asn1Parser, asn1Coding and asn1Decoding programs are now installed.
- Support constant size bit strings, as in 'BIT STRING (SIZE(42))'.
Reported by Cyril Holweck <cyril.holweck@q-free.com>.
- Add two more APIs required by GnuTLS.
- New public APIs:
asn1_find_node function
asn1_copy_node
makeinfo if no native makeinfo executable exists. Honor TEXINFO_REQD
when determining whether the native makeinfo can be used.
* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.
* Get rid of all the "split" argument deduction for makeinfo since
the PLIST module already handles varying numbers of split info files
correctly.
NOTE: Platforms that have "makeinfo" in the base system should check
that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
correct.
developer is officially maintaining the package.
The rationale for changing this from "tech-pkg" to "pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list). Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.
