This raises the log level of messages treated as FORMERR to NOTICE
when transfering in a zone. This also adds a missing log message
for TYPE0 and meta types received during a zone transfer.
7a78a85b moved the destruction of the validator from near the start
validated to the end. This reversed the order of dns_validator_destroy
and fetchctx_detach. Restore the order so that val->name remains
valid for the lifetime of the validator.
There are libraries which are reported in printversion(), but not
reported in setup(). Synchronize the functions, so that the log
file could have the same information as reported by the 'named -V'
command execution.
The autoconf and named -V now prints used version of jemalloc. This
doesn't work with system supplied jemalloc, so in it prints `system`
instead in the autoconf and nothing in named -V output.
We now depend on explicitly creating memory arenas and disabling tcache
on those, and these features are not available with jemalloc < 4.
Instead of working around these issues, make the jemalloc >= 4.0.0 hard
requirement by looking for sdallocx() symbol that's only available from
that version.
The jemalloc < 4 was only used by RHEL 7 which is not supported since
BIND 9.19+.
This commit extends the internal memory management middleware code in
BIND so that memory contexts backed by dedicated jemalloc arenas can
be created. A new function (isc_mem_create_arena()) is added for that.
Moreover, it extends the existing code so that specialised memory
contexts can be created easily, should we need that functionality for
other future purposes. We have achieved that by passing the flags to
the underlying jemalloc-related calls. See the above
isc_mem_create_arena(), which can serve as an example of this.
Having this opens up possibilities for creating memory contexts tuned
for specific needs.
The dnssec-must-be-secure feature was added in the early days of BIND 9
and DNSSEC and it makes sense only as a debugging feature.
Remove the feature to simplify the code.
To follow current best practices, create a short SECURITY.md file in the
root of the repository that contains information about the project's
security policy and guidelines for reporting potential security issues.
Replace the relevant bits of text in other files with references to the
new SECURITY.md file, so that the relevant information only needs to be
maintained in one place.
Replace all occurrences of the generic security-officer@isc.org email
with a dedicated address for reporting BIND 9 security issues,
bind-security@isc.org.
instead of allowing a NULL nametree in dns_nametree_covered(),
require nametree to exist, and ensure that the nametrees defined
for view and resolver objects are always created.
name trees can now also hold trees of counters. each time a name
dns_nametree_add() is called with a given name, the counter for that
name is incremented; the name is not deleted until dns_nametree_delete()
is called the same number of times.
this is meant to be used for synth-from-dnssec, which is incremented for
each key defined at a name, and decremented when a key is removed, the
name must continue to exist until the number of keys has reached zero.
