as there is no further use of isc_task in BIND, this commit removes
it, along with isc_taskmgr, isc_event, and all other related types.
functions that accepted taskmgr as a parameter have been cleaned up.
as a result of this change, some functions can no longer fail, so
they've been changed to type void, and their callers have been
updated accordingly.
the tasks table has been removed from the statistics channel and
the stats version has been updated. dns_dyndbctx has been changed
to reference the loopmgr instead of taskmgr, and DNS_DYNDB_VERSION
has been udpated as well.
Previously:
* applications were using isc_app as the base unit for running the
application and signal handling.
* networking was handled in the netmgr layer, which would start a
number of threads, each with a uv_loop event loop.
* task/event handling was done in the isc_task unit, which used
netmgr event loops to run the isc_event calls.
In this refactoring:
* the network manager now uses isc_loop instead of maintaining its
own worker threads and event loops.
* the taskmgr that manages isc_task instances now also uses isc_loopmgr,
and every isc_task runs on a specific isc_loop bound to the specific
thread.
* applications have been updated as necessary to use the new API.
* new ISC_LOOP_TEST macros have been added to enable unit tests to
run isc_loop event loops. unit tests have been updated to use this
where needed.
this command runs dns_adb_dumpquota() to display all servers
in the ADB that are being actively fetchlimited by the
fetches-per-server controls (i.e, servers with a nonzero average
timeout ratio or with the quota having been reduced from the
default value).
the "fetchlimit" system test has been updated to use the
new command to check quota values instead of "rndc dumpdb".
Historically, the inline keyword was a strong suggestion to the compiler
that it should inline the function marked inline. As compilers became
better at optimising, this functionality has receded, and using inline
as a suggestion to inline a function is obsolete. The compiler will
happily ignore it and inline something else entirely if it finds that's
a better optimisation.
Therefore, remove all the occurences of the inline keyword with static
functions inside single compilation unit and leave the decision whether
to inline a function or not entirely on the compiler
NOTE: We keep the usage the inline keyword when the purpose is to change
the linkage behaviour.
This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
Remove the dynamic registration of result codes. Convert isc_result_t
from unsigned + #defines into 32-bit enum type in grand unified
<isc/result.h> header. Keep the existing values of the result codes
even at the expense of the description and identifier tables being
unnecessary large.
Additionally, add couple of:
switch (result) {
[...]
default:
break;
}
statements where compiler now complains about missing enum values in the
switch statement.
When `rndc stop` is received, the isc_app_shutdown() was being called
before response to the rndc client has been sent; as the
isc_app_shutdown() also tears down the netmgr, the message was never
sent and rndc would complain about connection being interrupted in the
middle of the transaction. We now postpone the shutdown after the rndc
response has been sent.
Add the code and documentation required to provide DNSSEC signing
status through rndc. This does not yet show any useful information,
just provide the command that will output some dummy string.
4708. [cleanup] Legacy Windows builds (i.e. for XP and earlier)
are no longer supported. [RT #45186]
4707. [func] The lightweight resolver daemon and library (lwresd
and liblwres) have been removed. [RT #45186]
4706. [func] Code implementing name server query processing has
been moved from bin/named to a new library "libns".
Functions remaining in bin/named are now prefixed
with "named_" rather than "ns_". This will make it
easier to write unit tests for name server code, or
link name server functionality into new tools.
[RT #45186]
allows named to provide stale cached answers when
the authoritative server is under attack.
See max-stale-ttl, stale-answer-enable,
stale-answer-ttl. [RT #44790]
4549. [func] Added support for the EDNS TCP Keepalive option
(RFC 7828). [RT #42126]
4548. [func] Added support for the EDNS Padding option (RFC 7830).
[RT #42094]
4411. [func] "rndc dnstap -roll" automatically rolls the
dnstap output file; the previous version is
saved with ".0" suffix, and earlier versions
with ".1" and so on. An optional numeric argument
indicates how many prior files to save. [RT #42830]
4056. [bug] Expanded automatic testing of trust anchor
management and fixed several small bugs including
a memory leak and a possible loss of key state
information. [RT #38458]
4055. [func] "rndc managed-keys" can be used to check status
of trust anchors or to force keys to be refreshed,
Also, the managed keys data file has easier-to-read
comments. [RT #38458]
4030. [func] "rndc delzone" is now applicable to zones that were
configured in named.conf, as well as zones that
were added via "rndc addzone". (Note, however, that
if named.conf is not also modified, the deleted zone
will return when named is reloaded.) [RT #37887]
4029. [func] "rndc showzone" displays the current configuration
of a specified zone. [RT #37887]
4005. [func] The buffer used for returning text from rndc
commands is now dynamically resizable, allowing
arbitrarily large amounts of text to be sent back
to the client. (Prior to this change, it was
possible for the output of "rndc tsig-list" to be
truncated.) [RT #37731]
3867. [func] "rndc nta" can now be used to set a temporary
negative trust anchor, which disables DNSSEC
validation below a specified name for a specified
period of time (not exceeding 24 hours). This
can be used when validation for a domain is known
to be failing due to a configuration error on
the part of the domain owner rather than a
spoofing attack. [RT #29358]
information will be automatically updated if the
OS supports routing sockets. Use
"automatic-interface-scan no;" to disable.
Add "rndc scan" to trigger a scan. [RT #23027]
report the files that were being used so they can
be cleaned up if desired. [RT #27899]
