The rewrite of BIND 9 build system is a large work and cannot be reasonable
split into separate merge requests. Addition of the automake has a positive
effect on the readability and maintainability of the build system as it is more
declarative, it allows conditional and we are able to drop all of the custom
make code that BIND 9 developed over the years to overcome the deficiencies of
autoconf + custom Makefile.in files.
This squashed commit contains following changes:
- conversion (or rather fresh rewrite) of all Makefile.in files to Makefile.am
by using automake
- the libtool is now properly integrated with automake (the way we used it
was rather hackish as the only official way how to use libtool is via
automake
- the dynamic module loading was rewritten from a custom patchwork to libtool's
libltdl (which includes the patchwork to support module loading on different
systems internally)
- conversion of the unit test executor from kyua to automake parallel driver
- conversion of the system test executor from custom make/shell to automake
parallel driver
- The GSSAPI has been refactored, the custom SPNEGO on the basis that
all major KRB5/GSSAPI (mit-krb5, heimdal and Windows) implementations
support SPNEGO mechanism.
- The various defunct tests from bin/tests have been removed:
bin/tests/optional and bin/tests/pkcs11
- The text files generated from the MD files have been removed, the
MarkDown has been designed to be readable by both humans and computers
- The xsl header is now generated by a simple sed command instead of
perl helper
- The <irs/platform.h> header has been removed
- cleanups of configure.ac script to make it more simpler, addition of multiple
macros (there's still work to be done though)
- the tarball can now be prepared with `make dist`
- the system tests are partially able to run in oot build
Here's a list of unfinished work that needs to be completed in subsequent merge
requests:
- `make distcheck` doesn't yet work (because of system tests oot run is not yet
finished)
- documentation is not yet built, there's a different merge request with docbook
to sphinx-build rst conversion that needs to be rebased and adapted on top of
the automake
- msvc build is non functional yet and we need to decide whether we will just
cross-compile bind9 using mingw-w64 or fix the msvc build
- contributed dlz modules are not included neither in the autoconf nor automake
Previously, the dns_name API used isc_thread_key API for TLS, which is
fairly complicated and requires initialization of memory contexts, etc.
This part of code was refactored to use a ISC_THREAD_LOCAL pointer which
greatly simplifies the whole code related to storing TLS variables.
'isc_commandline_index' is a global variable so it can theoretically
change result between if expressions. Save 'argv[isc_commandline_index]'
to local variable 'arg1' and use 'arg1 == NULL' in if expressions
instead of 'argc < isc_commandline_index + 1'. This allows clang
to correctly determine what code is reachable.
This second commit uses second semantic patch to replace the calls to
dns_name_copy() with NULL as third argument where the result was stored in a
isc_result_t variable. As the dns_name_copy(..., NULL) cannot fail gracefully
when the third argument is NULL, it was just a bunch of dead code.
Couple of manual tweaks (removing dead labels and unused variables) were
manually applied on top of the semantic patch.
This makes the `-12a` options to `dnssec-dsfromkey` work more like
`dnssec-cds`, in that you can specify more than one digest and you
will get multiple records. (Previously you could only get one
non-default digest type at a time.)
The default is now `-2`. You can get the old behaviour with `-12`.
Tests and tools that use `dnssec-dsfromkey` have been updated to use
`-12` where necessary.
This is for conformance with the DS/CDS algorithm requirements in
https://tools.ietf.org/html/draft-ietf-dnsop-algorithm-update
Use them in structs for various rdata types where they are missing.
This doesn't change the structs since we are replacing explicit
uint8_t field types with aliases for uint8_t.
Use dns_dsdigest_t in library function arguments.
Improve dnssec-cds with these more specific types.
* Alphabetize the option lists in the man page and help text
* Make the synopses more consistent between the man page and help
text, in particular the number of different modes
* Group mutually exclusive options in the man page synopses, and order
options so that it is more clear which are available in every mode
* Expand the DESCRIPTION to provide an overview of the output modes
and input modes
* Improve cross-references between options
* Leave RFC citations to the SEE ALSO section, and clarify which RFC
specifies what
* Clarify list of digest algorithms in dnssec-dsfromkey and dnssec-cds
man pages
We can remove this, because it is used in `strtodsdigest` but that
already no longer covers the algorithm name "GOST".
There is one more GOST reference in `bin/python/isc/checkds.py.in`
but that is used for presentation format and probably should stay.
(cherry picked from commit 57d44fbc628d3c7dafdd545f6b83dbdcdc39a986)
- Replace external -DOPENSSL/-DPKCS11CRYPTO with properly AC_DEFINEd
HAVE_OPENSSL/HAVE_PKCS11
- Don't enforce the crypto provider from platform.h, just from dst_api.c
and configure scripts
The three functions has been modeled after the arc4random family of
functions, and they will always return random bytes.
The isc_random family of functions internally use these CSPRNG (if available):
1. getrandom() libc call (might be available on Linux and Solaris)
2. SYS_getrandom syscall (might be available on Linux, detected at runtime)
3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X)
4. crypto library function:
4a. RAND_bytes in case OpenSSL
4b. pkcs_C_GenerateRandom() in case PKCS#11 library
Replace dns_fixedname_init() calls followed by dns_fixedname_name()
calls with calls to dns_fixedname_initname() where it is possible
without affecting current behavior and/or performance.
This patch was mostly prepared using Coccinelle and the following
semantic patch:
@@
expression fixedname, name;
@@
- dns_fixedname_init(&fixedname);
...
- name = dns_fixedname_name(&fixedname);
+ name = dns_fixedname_initname(&fixedname);
The resulting set of changes was then manually reviewed to exclude false
positives and apply minor tweaks.
It is likely that more occurrences of this pattern can be refactored in
an identical way. This commit only takes care of the low-hanging fruit.
4757. [func] New "dnssec-cds" command creates a new parent DS
RRset based on CDS or CDNSKEY RRsets found in
a child zone, and generates either a dsset file
or stream of nsupdate commands to update the
parent. Thanks to Tony Finch. [RT #46090]
3786. [func] Provide more detailed error codes when using
native PKCS#11. "pkcs11-tokens" now fails robustly
rather than asserting when run against an HSM with
an incomplete PCKS#11 API implementation. [RT #35479]
3705. [func] "configure --enable-native-pkcs11" enables BIND
to use the PKCS#11 API for all cryptographic
functions, so that it can drive a hardware service
module directly without the need to use a modified
OpenSSL as intermediary (so long as the HSM's vendor
provides a complete-enough implementation of the
PKCS#11 interface). This has been tested successfully
with the Thales nShield HSM and with SoftHSMv2 from
the OpenDNSSEC project. [RT #29031]
