Instead of the explicit struct initializer with all member, rely on the fact
that static variables are explicitly initialized to 0 if not explicitly
initialized.
The MSVS C compiler requires every struct to have at least one member.
The dns_geoip_databases_t structure had one set of members for
HAVE_GEOIP and a different set for HAVE_GEOIP2, and none when neither
API is in use.
This commit silences the compiler error by moving the declaration of
dns_geoip_databases_t to types.h as an opaque reference, and commenting
out the contents of geoip.h when neither version of GeoIP is enabled.
Commit b104a9bc50 introduced unconditional
use of the ATOMIC_VAR_INIT() macro in bin/dnssec/dnssec-signzone.c even
though that macro is only defined on Unix platforms. Define it on
Windows systems as well in order to prevent build failures.
The ThreadSanitizer found several possible data races in our rwlock
implementation. This commit changes all the unprotected variables to atomic and
also changes the explicit memory ordering (atomic_<foo>_explicit(..., <order>)
functions to use our convenience macros (atomic_<foo>_<order>).
The SO_BSDCOMPAT socket option is no-op since Linux 2.4, see the manpage:
SO_BSDCOMPAT
Enable BSD bug-to-bug compatibility. This is used by the UDP protocol
module in Linux 2.0 and 2.2. If enabled, ICMP errors received for a UDP
socket will not be passed to the user program. In later kernel
versions, support for this option has been phased out: Linux 2.4
silently ignores it, and Linux 2.6 generates a kernel warning (printk())
if a program uses this option. Linux 2.0 also enabled BSD bug-to-bug
compatibility options (random header changing, skipping of the broadcast
flag) for raw sockets with this option, but that was removed in Linux
2.2.
The 'managed-keys' (and 'trusted-keys') options have been deprecated
by 'dnssec-keys'. Some documentation references to 'managed-keys'
had not yet been marked or noted as such.
Adds a new option to named-checkconf, -i. If set, named-checkconf
will not warn you about deprecated options. This allows people
to use named-checkconf in automated deployment precoesses where an
operator only cares if their conf is valid, even if it is not optimal.
This was added as a request as part of introducing a policy on
removing named.conf options.
- revise mapping of search terms to database types to match the
GeoIP2 schemas.
- open GeoIP2 databases when starting up; close when shutting down.
- clarify the logged error message when an unknown database type
is configured.
- add new geoip ACL subtypes to support searching for continent in
country databases.
- map geoip ACL subtypes to specific MMDB database queries.
- perform MMDB lookups based on subtype, saving state between
queries so repeated lookups for the same address aren't necessary.
- "--with-geoip" is used to enable the legacy GeoIP library.
- "--with-geoip2" is used to enable the new GeoIP2 library
(libmaxminddb), and is on by default if the library is found.
- using both "--with-geoip" and "--with-geoip2" at the same time
is an error.
- an attempt is made to determine the default GeoIP2 database path at
compile time if pkg-config is able to report the module prefix. if
this fails, it will be necessary to set the path in named.conf with
geoip-directory
- Makefiles have been updated, and a stub lib/dns/geoip2.c has been
added for the eventual GeoIP2 search implementation.
- when processing authoritative queries for ./NS, set 'gluedb' so
that glue will be included in the response, regardless of how
'minimal-responses' has been configured.
if "rndc reload" fails, the result code is supposed to be passed to
zone_postload, but for inline-signing zones, the result can be
overwritten first by a call to the ZONE_TRYLOCK macro. this can lead
to the partially-loaded unsigned zone being synced over to the signed
zone instead of being rejected.
Since commit 0771dd3be8, <isc/mem.h> no
longer includes <isc/xml.h>. On some systems (e.g. FreeBSD), this means
that no header included by lib/dns/dnsrps.c (and no header included by
those headers) contains a definition of free() any more, which triggers
a compiler warning as lib/dns/dnsrps.c calls that function. Add the
missing #include directive to prevent that warning from being triggered.
No function called dns_dnssecsignstats_decrement() actually exists.
Putting it into lib/dns/win32/libdns.def.in breaks at least some Windows
builds. Remove the nonexistent function from that file.
The ax_check_openssl m4 macro used OPENSSL_INCLUDES. Rename the
subst variable to OPENSSL_CFLAGS and wrap AX_CHECK_OPENSSL() in
action-if-not-found part of PKG_CHECK_MODULE check for libcrypto.
The json-c have previously leaked into the global namespace leading
to forced -I<include_path> for every compilation unit using isc/xml.h
header. This MR fixes the usage making the caller object opaque.
The libxml2 have previously leaked into the global namespace leading
to forced -I<include_path> for every compilation unit using isc/xml.h
header. This MR fixes the usage making the caller object opaque.
In addition to gather how many times signatures are created per
key in a zone, also count how many of those signature creations are
because of DNSSEC maintenance. These maintenance counters are
incremented if a signature is refreshed (but the RRset did not
changed), when the DNSKEY RRset is changed, and when that leads
to additional RRset / RRSIG updates (for example SOA, NSEC).
