TODO items. These are interesting todo items.
|
|
o understand synthesized DNAMEs, so those TTL=0 packets are cached properly.
|
|
o NSEC/NSEC3 aggressive negative caching, so that updates to NSEC/NSEC3
|
|
will result in proper negative responses.
|
|
o (option) where port 53 is used for send and receive, no other ports are used.
|
|
o (option) to not send replies to clients after a timeout of (say 5 secs) has
|
|
passed, but keep task active for later retries by client.
|
|
o (option) private TTL feature (always report TTL x in answers).
|
|
o (option) pretend-dnssec-unaware, and pretend-edns-unaware modes for workshops.
|
|
o delegpt use rbtree for ns-list, to avoid slowdown for very large NS sets.
|
|
o (option) reprime and refresh oft used data before timeout.
|
|
o (option) retain prime results in a overlaid roothints file.
|
|
o (option) store primed key data in a overlaid keyhints file (sort of like drafttimers).
|
|
o windows version, auto update feature, a query to check for the version.
|
|
o command the server with TSIG inband. get-config, clearcache,
|
|
get stats, get memstats, get ..., reload, clear one zone from cache
|
|
o NSID rfc 5001 support.
|
|
o timers rfc 5011 support.
|
|
o Treat YXDOMAIN from a DNAME properly, in iterator (not throwaway), validator.
|
|
o make timeout backoffs randomized (a couple percent random) to spread traffic.
|
|
o inspect date on executable, then warn user in log if its more than 1 year.
|
|
o (option) proactively prime root, stubs and trust anchors, feature.
|
|
early failure, faster on first query, but more traffic.
|
|
o library add convenience functions for A, AAAA, PTR, getaddrinfo, libresolve.
|
|
o library add function to validate input from app that is signed.
|
|
o add dynamic-update requests (making a dynupd request) to libunbound api.
|
|
o SIG(0) and TSIG.
|
|
o support OPT record placement on recv anywhere in the additional section.
|
|
o add local-file: config with authority features.
|
|
o (option) to make local-data answers be secure for libunbound (default=no)
|
|
o (option) to make chroot: copy all needed files into jail (or make jail)
|
|
perhaps also print reminder to link /dev/random and sysloghack.
|
|
o overhaul outside-network servicedquery to merge with udpwait and tcpwait,
|
|
to make timers in servicedquery independent of udpwait queues.
|
|
o check into rebinding ports for efficiency, configure time test.
|
|
o EVP hardware crypto support.
|
|
o option to ignore all inception and expiration dates for rrsigs.
|
|
o cleaner code; return and func statements on newline.
|
|
o memcached module that sits before validator module; checks for memcached
|
|
data (on local lan), stores recursion lookup. Provides one cache for multiple resolver machines, coherent reply content in anycast setup.
|
|
o no openssl_add_all_algorithms, but only the ones necessary, less space.
|
|
o listen to NOTIFY messages for zones and flush the cache for that zone
|
|
if received. Useful when also having a stub to that auth server.
|
|
Needs proper protection, TSIG, in place.
|
|
o winevent - do not go more than 64 fds (by polling with select one by
|
|
one), win95/98 have 100fd limit in the kernel, so this ruins w9x portability.
|
|
|
|
*** Features features, for later
|
|
* dTLS, TLS, look to need special port numbers, cert storage, recent libssl.
|
|
* aggressive negative caching for NSEC, NSEC3.
|
|
* multiple queries per question, server exploration, server selection.
|
|
* support TSIG on queries, for validating resolver deployment.
|
|
* retry-mode, where a bogus result triggers a retry-mode query, where a list
|
|
of responses over a time interval is collected, and each is validated.
|
|
or try in TCP mode. Do not 'try all servers several times', since we must
|
|
not create packet storms with operator errors.
|
|
o on windows version, implement that OS ancillary data capabilities for
|
|
interface-automatic. IPPKTINFO, IP6PKTINFO for WSARecvMsg, WSASendMsg.
|
|
o local-zone directive with authority service, full authority server
|
|
is a non-goal.
|
|
o infra and lame cache: easier size config (in Mb), show usage in graphs.
|
|
- store time of dump in cachedumps, so that on a load the ttls can be
|
|
compared to the absolute time, and now-expired items can be dealt with.
|
|
|
|
later
|
|
- selective verbosity; ubcontrol trace example.com
|
|
- cache fork-dump, pre-load
|
|
- for fwds, send queries to N servers in fwd-list, use first reply.
|
|
document high scalable, high available unbound setup onepager.
|
|
- prefetch DNSKEY when DS in delegation seen (nonCD, underTA).
|
|
- use libevent if available on system by default(?), default outgoing 256to1024
|
|
|
|
[1] BIND-like query logging to see who's looking up what and when
|
|
[2] more logging about stuff like SERVFAIL and REFUSED responses
|
|
[3] a Makefile that works without gnumake
