Updated 010-configure-uname.patch as source changed.
Removed 100-example-conf-in.patch as not needed any more.
Release message:
This release has a fix for the DNSBomb issue CVE-2024-33655. This has a
low severity for Unbound, since it makes Unbound complicit in targeting
others, but does not affect Unbound so much.
To mitigate the issue new configuration options are introduced.
The options discard-timeout: 1900, wait-limit: 1000
and wait-limit-cookie: 10000 are enabled by default. They limit the
number of outstanding queries that a querier can have. This limits
the reply pulse, and make Unbound less favorable for the issue.
With the config wait-limit-netblock and wait-limit-cookie-netblock
the parameters can be fine tuned for specific destinations.
More information on the attack and Unbound's mitigations are
presented further down.
Other fixes in this release are that Unbound no longer follows symlinks
when truncating the pidfile. Unbound also does not chown the pidfile,
this is for safety reasons. There are also a number of fixes for RPZ, in
handling CNAMEs. There is a memory leak fix for the edns client subnet
cache. For DNSSEC validation a case is fixed when the query is of type
DNAME. The unbound-anchor program is fixed to first write to a temporary
file, before replacing the original. This handles disk full situations,
and because of it unbound-anchor needs permission to create that file,
in the same directory as the original file. There is also a fix for
IP_DONTFRAG, to disable fragmentation instead of the opposite.
The option cache-min-negative-ttl can be used to set the minimum TTL
for negative responses in the cache. It complements existing options to
set the maximum ttl for negative responses and to set the minimum and
maximum ttl but not specifically for negative responses.
The option cachedb-check-when-serve-expired option makes Unbound use
cachedb to check for expired responses, when serve-expired is enabled,
and cachedb is used. It is enabled by default.
The -q option for unbound-checkconf can be added to silence it when
there are no errors.

Currently there is a problem with log spam when ipv6 network
is dropped. Fix this by backporting a patch to silence these errors
when verbose logging is not enabled.

ssl_set1_host() is not available without openssl-1.1.0. Unbound can not do
host cert verification. DNS over TLS connects, but hosts are unverified. A
patch for log err is added with a noitce in README.md.
(see: https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=658)
Also, squash some minor robustness and TLS usability fixes.

A vulnerability was discovered in the processing of wildcard synthesized
NSEC records. While synthesis of NSEC records is allowed by RFC4592,
these synthesized owner names should not be used in the NSEC processing.
This does, however, happen in Unbound 1.6.7 and earlier versions.

Unbound 1.6.1 has a few bug fixes for resource leaks,
configuration robustness, compile environment interaction,
and maintaining the trust anchor. The 2017 trust anchor
(DS) is built into unbound and unbound-anchor.
File /etc/unbound/root.key holds 2010/2017 DS record until 2018

Until now unbound was always running as root by default. A DNS resolver can
easily run under a non-privileged user.

The custom list of DNS root servers provided with the package is not necessary.
Unbound ships with a built-in list.

This is an import of the net/unbound package from Subversion
revision 40658 (May 2, 2014). The only change is the addition of
PKG_LICENSE, PKG_LICENSE_FILE and PKG_MAINTAINER to Makefile.
Unbound 1.4.22 is the current upstream release.
