Havard Eidnes c68f5a7a8d Fix various build warnings uncovered on NetBSD w/pkgsrc. 
The isxxxx() and toxxxx() functions have a limited well-defined
input value range, namely that of "unsigned char" plus EOF.  Cast
args accordingly.

Bring strncasecmp() into scope by including <strings.h>.

Jim Hague 3fe0c94357 Merge branch 'develop' into feature/abstract-tls 2019-01-14 19:09:20 +00:00
Jim Hague b0c057e8ae Update dependencies for GnuTLS. 
In practice a 'make depend' is required before building with either OpenSSL or GnuTLS.
 2018-12-06 16:35:43 +00:00
Jim Hague 46c49cbcfe Modify getdns_server_mon to use GnuTLS or OpenSSL. 
Untested.

Jim Hague 088d775117 In Keepalive test, send the maximum possible timeout value to the server. 
The response will then show the server's value.

Jim Hague 13d7a730ee Further mitigate cache effects for OOOR by adding random label to delay lookup. 
It turns out that delay.getdnsapi.net only pays attention to the left-most label.
 2018-02-07 12:41:24 +00:00
Jim Hague a25f832d8a Remove timeout argument from keepalive test. 
The client doesn't send a timeout value to the server, so there's no point having this argument.
 2018-02-01 16:04:22 +00:00
Jim Hague 3b5657e580 Reduce delay on OOOR delayed lookup. 
A delay of 1000ms was causing frequent lookup timeouts e.g. on 9.9.9.9. We hypothesise that the delay causes an internal timeout in the server to fire. So reduce the delay to a smaller value that seems to leave the test working but reduces the incidence of timeouts.

We observe this still leaves timeouts on TLS connections to 9.9.9.9. These seem to occur only on TLS connections, and reducing the delay much further does not alter the observed behaviour. We guess there is something else going on there.

Jim Hague 037f6039c8 Improve AsciiDoc table formatting. 2018-01-23 13:53:08 +00:00
Jim Hague 01ea1d6a22 Note TLS 1.3 is experimental. At least until we find a stable test server. 2018-01-23 13:47:31 +00:00
Jim Hague b0661b9d9f Add a tool README. 
Use AsciiDoc for this, as the GitHub table support in Markdown is woeful. But AsciiDoc is always better than Markdown anyway.
 2018-01-23 13:45:55 +00:00
Jim Hague 8ba53f10b6 Correct RTT warning and critical default thresholds. 2018-01-23 13:45:09 +00:00
Jim Hague fcaa4f9845 Reflow usage message entry. 2018-01-23 12:37:14 +00:00
Jim Hague f3b2f83879 More output tittivating. Make verbose by default in non-monitoring mode. 2018-01-23 12:14:40 +00:00
Jim Hague a4f17760ab Revise rcode_text() to get text from getdns, and add rrtype_text(). 2018-01-23 12:13:59 +00:00
Jim Hague 7e884e2cd0 Rename concurrent to OOOR (Out Of Order Responses). 2018-01-23 11:30:12 +00:00
Jim Hague bedd3a02cf Revise concurrency test to use <n>.delay.getdnsapi.net. 
This gives more secure results than the previous method.
 2018-01-22 17:39:25 +00:00
Jim Hague 1e774a95f5 Don't rely on GCC extensions. 2018-01-22 16:49:53 +00:00
Jim Hague 8c3047dbe0 Add 'concurrent' test 
The concurrent test works by sending a known good query synchronously,
and then sending asynchronous queries for three random TLDs followed by
the known good query. The latter should be answerable from cache, and so
give a result before at least one of the random TLDs.
 2018-01-22 16:49:53 +00:00
Jim Hague f9e4c9f853 Revise output. 
If in monitoring mode, make output conform to Nagios norms. This starts with the probe type and result, so we need to save output generated during the operation and print it at the end.

If not in monitoring mode, make the formatting more expansive.
 2018-01-22 14:36:54 +00:00
Jim Hague 0291e205fd Add TLS 1.3 test. 
Add a new item tls_version to call_reporting, containing the OpenSSL version string for the name of the protocol used for the connection.

The test does a normal lookup, but first sets the cipher list to TLS1.3 only ciphers. This will cause a Bad Context error at search time, so we can tell if the underlying OpenSSL library lacks TLS 1.3. The check the call reporting for a TLS version of "TLSv1.3".
 2018-01-19 15:56:40 +00:00
Jim Hague 62ad159f15 Update dnssec-validate. Check we can retrieve info for bogus domain, and remove must use TCP flag. 
Run a second query with the CD bit set and check that succeeds.
 2018-01-19 14:51:46 +00:00
Jim Hague 3fd4f7f240 Add 'dnssec-validate' test. 
This test checks whether the server does DNSSEC validation. If it manages to find an A record for dnssec-failed.org, it doesn't.
 2018-01-19 14:51:46 +00:00
Jim Hague 1a3025a405 If server does not return expected TXT in qname-min, return UNKNOWN not WARNING. 2018-01-18 17:17:16 +00:00
Jim Hague ea035fa82e Correct some code formatting. 2018-01-18 17:16:28 +00:00
Jim Hague add818fea2 Remove dependency on timegm() when using OpenSSL < 1.0.2. 
Convert dates to Julian and diff. This is basically what ASN1_TIME_diff() does internally.

And that's quite enough near-pointless polishing here.
 2018-01-18 10:55:44 +00:00
Jim Hague 00c17dca14 Add to certificate time conversion to cope with pre-1.0.2 OpenSSL. Also tag printed time with UTC. 
The time parse with pre-1.0.2 is a best effort, and relies on timegm() to convert struct tm in UTC to time_t. There being attractive alternative. Isn't C time handling grotty?
 2018-01-17 18:38:28 +00:00
Jim Hague 760269acbd Make internal types POSIX-compliant by not naming them *_t. 
See: http://pubs.opengroup.org/onlinepubs/9699919799/xrat/V4_xsh_chap02.html#tag_22_02_12_01

The change tacitly ignores the colossal number of coach and horses the entire world, including getdns, has stampeded through this POSIX hope for decades, but simply hopes for some small recognition when the Recording Angel tots up the damages.
 2018-01-17 15:35:56 +00:00
Jim Hague 6bd0f8b980 Encode exit status words in () to make it clear that it's not part of the sentence. 
'Server validates OK' -> 'Server validates (OK)'
 2018-01-17 15:24:17 +00:00
Jim Hague 3666d994a7 Add 'keepalive' test and supporting changes to getdns library. 
Checking for server support for keepalive means we need to know if the server did send a keepalive option to the client. This information is not currently exposed in getdns, so add a flag 'server_keepalive_received' to call_reporting. This is 0 if not received, 1 if received. If received, the actual timeout is in 'idle timeout in ms', though watch out for the overflow alternative.
