Replace dns_fixedname_init() calls followed by dns_fixedname_name()
calls with calls to dns_fixedname_initname() where it is possible
without affecting current behavior and/or performance.
This patch was mostly prepared using Coccinelle and the following
semantic patch:
@@
expression fixedname, name;
@@
- dns_fixedname_init(&fixedname);
...
- name = dns_fixedname_name(&fixedname);
+ name = dns_fixedname_initname(&fixedname);
The resulting set of changes was then manually reviewed to exclude false
positives and apply minor tweaks.
It is likely that more occurrences of this pattern can be refactored in
an identical way. This commit only takes care of the low-hanging fruit.
4307. [bug] "dig +subnet" and "mdig +subnet" could send
incorrectly-formatted Client Subnet options
if the prefix length was not divisble by 8.
Also fixed a memory leak in "mdig". [RT #45178]
4303. [bug] "dig +subnet" was unable to send a prefix length of
zero, as it was incorrectly changed to 32 for v4
prefixes or 128 for v6 prefixes. In addition to
fixing this, "dig +subnet=0" has been added as a
short form for 0.0.0.0/0. The same changes have
also been made in "mdig". [RT #41553]
response when there is a malformed EDNS option.
[RT #39647]
4153. [bug] Dig should zero non significant +subnet bits. Check
that non significant ECS bits are zero on receipt.
[RT #39647]
experimental SIT option of BIND 9.10. The following
named.conf directives are avaliable: send-cookie,
cookie-secret, cookie-algorithm and nocookie-udp-size.
The following dig options are available:
+[no]cookie[=value] and +[no]badcookie. [RT #39928]
