The 850e9e59bf commit intended to recreate
the HTTPS and TLS interfaces during reconfiguration, but they are being
recreated also during regular interface re-scans.
Make sure the HTTPS and TLS interfaces are being recreated only during
reconfiguration.
Mutex profiling code (used when the ISC_MUTEX_PROFILE preprocessor macro
is set to 1) has been broken for the past 3 years (since commit
0bed9bfc28) and nobody complained, which
is a strong indication that this code is not being used these days any
more. External tools for both measuring performance and detecting
locking issues are already wired into various GitLab CI checks. Drop
all code depending on the ISC_MUTEX_PROFILE preprocessor macro being
set.
It's unclear if we are going to keep it or not, so let's mark it as
deprecated for a good measure. It's easier to un-deprecate it than the
other way around.
A number of DNS implementation produce NSEC records with bad type
maps that don't contain types that exist at the name leading to
NODATA responses being synthesize instead of the records in the
zone. NSEC records with these bad type maps often have the NSEC
NSEC field set to '\000.QNAME'. We look for the first label of
this pattern.
e.g.
example.com NSEC \000.example.com SOA NS NSEC RRSIG
example.com RRRSIG NSEC ...
example.com SOA ...
example.com RRRSIG SOA ...
example.com NS ...
example.com RRRSIG NS ...
example.com A ...
example.com RRRSIG A ...
A is missing from the type map.
This introduces a temporary option 'reject-000-label' to control
this behaviour.
This sets as many server options as possible at once to detect
cut-and-paste bugs when implementing new server options in peer.c.
Most of the accessor functions are similar and it is easy to miss
updating a macro name or structure element name when adding new
accessor functions.
checkconf/setup.sh is there to minimise the difference to branches
with optional server options where the list is updated at runtime.
'server <prefix> { broken-nsec yes; };' can now be used to stop
NSEC records from negative responses from servers in the given
prefix being cached and hence available to synth-from-dnssec.
dns_db_nodecount can now be used to get counts from the auxilary
rbt databases. The existing node count is returned by
tree=dns_dbtree_main. The nsec and nsec3 node counts by dns_dbtree_nsec
and dns_dbtree_nsec3 respectively.
construct a test zone which contains a minimal NSEC record,
emit priming queries for this record, and then check that
a respose that would be synthesised from it isn't.
The TCP connection reset test starts mock UDP and TCP server which
always returns empty DNS answer with TC bit set over UDP and resets the
TCP connection after five seconds.
When tested without the fix, the DNS query to 10.53.0.2 times out and
the ns2 server hangs at shutdown.
Add a idna that checks whether non-character letters like _ and * are
preserved when IDN is enabled. This wasn't the case when
UseSTD3ASCIIRules were enabled, f.e. _ from _tcp would get mangled to
tcp.
Disable IDN2_USE_STD3_ASCII_RULES to the libidn2 conversion because it
broke encoding some non-letter but valid domain names like _tcp or *.
This reverts commit ef8aa91740.
This change is made in particular to address the issue with 'doth'
system tests where servers are unable to iniitalise in time in CI
system under high load (that happened particularly often for Debian
Buster cross32 configuration).
The right solution, is, of course, to (re)use TLS context sparingly,
while right now we create too many of them.
This commit ensure that the 'tls' name specified in the 'primaries'
clause of a 'zone' statement is a valid one.
Prior to that such a name would be silently accepted, leading to
silent XFRs-via-TLS failures.
This commit adds support for client-side TLS parameters to XoT.
Prior to this commit all client-side TLS contexts were using default
parameters only, ignoring the options from the BIND's configuration
file.
Currently, the following 'tls' parameters are supported:
- protocols;
- ciphers;
- prefer-server-ciphers.
This commit adds a new system-test: transport-acl system test. It is
intended to test the new, extended syntax for ACLs, the one where port
or transport protocol can be specified. Currently, it includes the
tests only using allow-transfer statement, as this extended syntax is
used only there, at least for now.
This commit extends the 'doth' system test to verify that the new
extended 'allow-transfer' option syntax featuring 'port' and
'transport' parameters is supported and works as expected. That is, it
restricts the primary server to allow zone transfers only via XoT.
Additionally to that, it extends the 'checkonf' test with more
configuration file examples featuring the new syntax.
This commit extends ACL syntax handling code with 'port' and
'transport' options. Currently, the extended syntax is available only
for allow-transfer options.
This commit adds an isc_nm_socket_type() function which can be used to
obtain a handle's socket type.
This change obsoletes isc_nm_is_tlsdns_handle() and
isc_nm_is_http_handle(). However, it was decided to keep the latter as
we eventually might end up supporting multiple HTTP versions.
