* Remove unused extern variable in openssl(1) s_timeinoguchi2018-01-071-2/+1
| | | | | | | | | This extern variable appears not to be used. And it is overridden by local variable in doConnection(). This causes MSVC warning C4459 "declaration of 'verify_error' hides global declaration". OK millert@
* Seperate real and user timer interfacesjca2017-12-054-17/+15
| | | | | | | | | Use more descriptive names, and make it clearer that real and user timers work on different static storage. The end goal is to be able to reuse those timer functions, instead of inlining other timer implementations subject to clock jumps. Discussed with Scott Cheloha
* Mixing -url with any of -host, -port, or -path should be a usage errorguenther2017-11-291-7/+8

* Allow TLS ciphers and protocols to be specified for nc(1).jsing2017-11-282-41/+65
| | | | | | | | | | | Replace the "tlscompat" and "tlsall" options with "cipher" and "protocol" options that are key/value pairs. This allows the user to specify ciphers and protocols in a form that are accepted by tls_config_set_ciphers() and tls_config_set_protocols() respectively. ok beck@ (also ok jmc@ for a previous revision of the man page).
* Use clock_gettime and getrusage to compute real and user time.jca2017-11-241-16/+33

* If -P and -c were given, a second pledge call tried to add "rpath" to thetb2017-06-101-8/+5
| | | | | | | | | | | | first pledge promises, so nc exited with EPERM. To fix this, merge the pledge of the Pflag && usetls case into the first pledge block. This allows us to get rid of the second pledge block and thus to simplify the logic a bit. While there, add a missing blank to an error string. Joint effort by the #openbsd-daily code reading group, problem found and initial patch by <rain1 openmailbox org>. ok awolk
