Also, add "set -e" to all shell scripts of the views test to exit when
any command fails or is unknown, e.g., this on OpenBSD:
tests.sh[174]: seq: not found
The seq command is not defined in the POSIX standard and is missing on
OpenBSD. Given that the system test code is meant to be POSIX-compliant
replace it with a shell construct.
This function has never been used since it was added to the source tree
by commit 686b27bfd3 back in 1999. As
the dns_zoneflg_t type is only defined in lib/dns/zone.c, no function
external to that file would be able to use dns_zone_setflag() properly
anyway - the DNS_ZONE_SETFLAG() and DNS_ZONE_CLRFLAG() macros should be
used instead. Zone options that can be set from outside zone.c are set
using dns_zone_setoption().
Add two tests to make sure named-checkconf catches key-directory issues
where a zone in multiple views uses the same directory but has
different dnssec-policies. One test sets the key-directory specifically,
the other inherits the default key-directory (NULL, aka the working
directory).
Also update the good.conf test to allow zones in different views
with the same key-directory if they use the same dnssec-policy.
Also allow zones in different views with different key-directories if
they use different dnssec-policies.
Also allow zones in different views with the same key-directories if
only one view uses a dnssec-policy (the other is set to "none").
Also allow zones in different views with the same key-directories if
no views uses a dnssec-policy (zone in both views has the dnssec-policy
set to "none").
Don't allow the same zone with different dnssec-policies in separate
views have the same key-directory.
Track zones plus key-directory in a symtab and if there is a match,
check the offending zone's dnssec-policy name. If the name is "none"
(there is no kasp for the offending zone), or if the name is the same
(the zone shares keys), it is fine, otherwise it is an error (zones
in views using different policies cannot share the same key-directory).
Resolve "Misleading diagnostic in update_soa_serial indicates BIND will use increment but it doesn't"
Closes#2696

if dns_updatemethod_date is used do that the returned method is only
set to dns_updatemethod_increment if the new serial does not encode
the current day (YYYYMMDDXX).
PyLint 2.8.2 reports the following suggestions for two Python scripts
used in the system test suite:
************* Module tests_rndc_deadlock
bin/tests/system/addzone/tests_rndc_deadlock.py:71:4: R1732: Consider using 'with' for resource-allocating operations (consider-using-with)
************* Module tests-shutdown
bin/tests/system/shutdown/tests-shutdown.py:68:4: R1732: Consider using 'with' for resource-allocating operations (consider-using-with)
bin/tests/system/shutdown/tests-shutdown.py:154:8: R1732: Consider using 'with' for resource-allocating operations (consider-using-with)
Implement the above suggestions by using
concurrent.futures.ThreadPoolExecutor() and subprocess.Popen() as
context managers.
Add an item to the CVE issue template which calls for drafting the
security advisory early in the security incident handling process. The
intention is to ensure there is enough time to review and polish ISC
security advisories before they get published.
Tweak the release checklist to make sure we carefully consider all
confidential issues before opening them up to the public. This change
is intended as a safeguard against accidentally disclosing too much
information about a security vulnerability before our users get a chance
to patch it.
Instead of using fixed quantum, this commit adds atomic counter for
number of items on each queue and uses the number of netievents
scheduled to run as the limit of maximum number of netievents for a
single process_queue() run.
This prevents the endless loops when the netievent would schedule more
netievents onto the same loop, but we don't have to pick "magic" number
for the quantum.
OpenBSD changed the name of the pytest script from py.test-3 in OpenBSD
6.8 to py.test in OpenBSD 6.9.
The py.test-3 name which was added in d5562a3e for the sake of OpenBSD
and CentOS is still required for CentOS.
This commit adds a new configuration option to set the receive and send
buffer sizes on the TCP and UDP netmgr sockets. The default is `0`
which doesn't set any value and just uses the value set by the operating
system.
There's no magic value here - set it too small and the performance will
drop, set it too large, the buffers can fill-up with queries that have
already timeouted on the client side and nobody is interested for the
answer and this would just make the server clog up even more by making
it produce useless work.
The `netstat -su` can be used on POSIX systems to monitor the receive
and send buffer errors.
