5d4e30eb13 Replace console output by monitoring events for curve security issues (#2645)
* Fixing #2002 one way of doing it

 * Mechanisms can implement a new method `error_detail()`
 * This error detail have three values for the moment: no_detail
 (default), protocol, encryption.
    + generic enough to make sense for all mechanisms.
    - low granularity level on information.

* Fixing #2002: implementation of the error details

The ZMQ_EVENT_HANDSHAKE_FAILED event carries the error details
as value.

* Removed Microsoft extenstion for enum member access

This was leading to compilation error under linux.

* Adaptation of CURVE test cases

* Monitoring event: changed API for detailed events

Removed ZMQ_EVENT_HANDSHAKE_FAILED and replaced it by:
- ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL,
- ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL,
- ZMQ_EVENT_HANDSHAKE_FAILED_ENCRYPTION

Adaptation of text case `security_curve`

* Removed event value comparison

This was introduced for the previous API model adaptation

* Removed the prints in std output and added missing details

`current_error_detail` was not set in every protocol error cases

* Fixed initialization of current_error_detail

* Fixed error in greeting test case

The handshake failure due to mechanism mismatch in greeting is actually
a protocol error. The error handling method consider it like so and
send a protocol handshake failure monitoring event instead of no_detail.

Fixed the test_security_curve expectation as well.

* Upgraded tests of monitoring events

The tests check the number of monitoring events received

* Problem: does not build under Linux or without ZMQ_DRAFT_API

Solution:
- properly use ZMQ_DRAFT_API conditional compilation
- use receive timeouts instead of Sleep

* Problem: duplicate definition of variable 'timeout'

Solution: merged definitions

* Problem: inconsistent timing dependencies

Solution: reduce timing dependency by using timeouts at more places

* Problem: assertion failure under Linux due to unexpected monitor event

Solution: output event type to aid debugging

* Problem: erroneous assertion code

* Problem: assertion failure with a garbage server key due to an extra third event

Solution: changed assertion to expect three events (needs to be checked)

* Problem: extra include directive to non-existent file

Solution: removed include directive

* Problem: assertion failure on appveyor for unknown reason

Solution: improve debug output

* Problem: no build with libsodium and draft api

Solution: add build configurations with libsodium and draft api

* Problem: assertion failure on CI

Solution: change assertion to reflect actual behaviour on CI (at least temporarily)

* Problem: error in condition in assertion code

* Problem: assertion failure on CI

Solution: generalize assertion to match behavior on CI

* Problem: assertion failures on CI

Solution: removed inconsistent assertion on no monitor events before flushing
improved debuggability by converting function into macro

* Problem: diverging test code for three analogous test cases with garbage key

Solution: extract common code into function

* Problem: does not build without ZMQ_BUILD_DRAFT_API

Solution: introduce dummy variable

* Attempt to remove workaround regarding ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL again

* Problem: EAGAIN error after handshake complete if there is no more data in inbuffer

Solution: Skip tcp_read attempt in that case

* Problem: handshaking event emitted after handshaking failed

Solution: use stream_engine_t::handshaking instead of mechanism_t::status() to determine whether still handshaking

* Include error code in debug output

* Improve debugging output: output flushed events

* Split up ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL into ZMQ_EVENT_HANDSHAKE_FAILED_ZMTP and ZMQ_EVENT_HANDSHAKE_FAILED_ZAP

* Fixed compilation without ZMQ_BUILD_DRAFT_API

* Renamed ZMQ_EVENT_HANDSHAKE_SUCCEED to ZMQ_EVENT_HANDSHAKE_SUCCEEDED for language consistency

* Renamed ZMQ_EVENT_HANDSHAKE_SUCCEED to ZMQ_EVENT_HANDSHAKE_SUCCEEDED for language consistency

* Renamed ZMQ_EVENT_HANDSHAKE_SUCCEED to ZMQ_EVENT_HANDSHAKE_SUCCEEDED for language consistency

* Fixed assert_monitor_event (require event instead of allowing no event)
Reverted erroneous change to handshaking condition
Renamed test_wrong_key to test_garbage_key
Generalized assumption in test_garbage_key to allow for ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL with error == EPIPE

* Better isolate test cases from each other by providing a fresh context & server for each

* Added diagnostic output

* Changed assertion to reflect actual behavior on CI

* Fixed formatting, observe maximum line length

* Fixed formatting, observe maximum line length

* Increase timeout to check if this fixes valgrind run

* Close server with close_zero_linger

* Increase timeout to check if this fixes valgrind run

* Increase timeout to check if this fixes valgrind run

* Generalize assertion to also work with valgrind

* Fixed formatting

* Add more diagnostic output

* Generalize assertion to also work with valgrind

5934919f3e Problem: tests bind to hardcoded TCP ports
Solution: use ZMQ_LAST_ENDPOINT in most places. This alllows running
tests in paralle, and on over-booked shared machines where many of
the ports would be already in use.
Keep 3 tests with an hardcoded port, as there are some code paths that
require it (eg: connect before bind), but list those ports in
tests/testutil.hpp as macros so that they do not overlap and still
allow parallel runs.

These changes were inspired by a patch uploaded to Ubuntu by the
package maintainer, Steve Langasek <steve.langasek@ubuntu.com>.
Thank you Steve!

c0e2bc4ef9 Problem: new DRAFT monitor events returned even without --enable-draft
Solution: wrap the event triggering in the DRAFT ifdef as well as the
defines. This ensures that the event are returned only if the
library was built with DRAFTs enabled.

Also update the test case to expect the new events since it uses
the catch-all mask. Although the sequence of event is different and
this might be considered as an API breakage, using the catch-all
ZMQ_EVENT_ALL mask implies that, well, all events are monitored so
it's normal that new ones will be added.
Users that don't want this kind of behaviour to change can simply
monitor only the event that they care about.

e449d7bfbd Fix test flakiness.
I'm pretty sure this is an issue with the test being too picky and not a
bug, but the behavior in this situation is not well documented.

8620c3e032 Problem: source file headers are somewhat confusing about LGPLv3
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.

Solution: specify these grants in the header of each source file.

9753de8566 Problem: zmq_socket_monitor code is dirty
Specifically:

* zmq_event_t should not be used internally in libzmq, it was
  meant to be an outward facing structure.

* In 4.x, zmq_event_t does not correspond to monitor events, so
  I removed the structure entirely.

* man page for zmq_socket_monitor is incomplete and the example
  code was particularly nasty.

* test_monitor.cpp needed rewriting, it was not clean.

cf20932df0 Add "#undef NDEBUG" to all tests.
This change makes sure that even if the tests are built in a
"release" configuration (with optimizations and NDEBUG turned on),
the assertions won't get compiled out of the tests themselves.

The C standard guarantees that the most recent inclusion of
<assert.h> is the one that counts, so it's important that the
"#undef NDEBUG/#include <assert.h>" come as the last thing in
the block of header files.

"testutil.hpp" includes <assert.h>, so I've left <assert.h> out
of any test that #includes "testutil.hpp", just for the sake of
brevity.

c29aef4dd8 Verify the value of the "void *s" passed to the monitor function.
This formerly unused parameter actually represents the socket
on which the event was received. As such, we should check that
its value makes sense: it must be either "rep" or "req", and in
the case of some kinds of events, it must be specifically one
or the other.

After this change, "s" is no longer unused.

f718d2bead Fix a bug reported on the mailing list.
Both memcmp and strcmp return zero on equal, nonzero on nonequal;
so all of these tests were backwards.

The original committer fixed the failure by comparing 22 bytes instead
of the correct 21, so that the assertions would trigger only if the
22nd byte happened to match exactly --- which was rare.

The correct fix is to compare the right number of bytes with the
right sense.  (I think all of the ".addr" fields are null-terminated,
in which case it's more appropriate to use strcmp throughout.)

c995de6584 Allow the ZMQ_MONITOR code compilable on gcc 4.7 on Linux.
The current ZMQ_MONITOR code does not compile in gcc 4.7, as -pedantic
and -Werror are enabled, and ISO C++ doesn't allow casting between
normal pointers (void*) and function pointers, as pedantically their
size could be different. This caused the library not compilable. This
commit workaround the problem by introducing one more indirection, i.e.
instead of calling

    (void *)listener

which is an error, we have to use

    *(void **)&listener

which is an undefined behavior :) but works on most platforms

Also, `optval_ = monitor` will not set the parameter in getsockopt(),
and the extra casting caused the LHS to be an rvalue which again makes
the code not compilable. The proper way is to pass a pointer of function
pointer and assign with indirection, i.e. `*optval_ = monitor`.

Also, fixed an asciidoc error in zmq_getsockopt.txt because the `~~~~`
is too long.
