90f091abf3 Problem: IPV6_TCLASS setsockopt fails on IPv4 socket 
Solution: if setsockopt errors out and errno is set to ENOPROTOOPT
(or EINVAL on OSX) ignore it and carry on.

Make ZMQ_TOS work with IPv6 sockets
 2016-11-14 11:37:24 +01:00
Saif Hasan
fc8007e896 Make ZMQ_TOS work with IPv6 sockets 
Summary:
To set `Type Of Service` for IP layer packets ZMQ provides `ZMQ_TOS` socket
option. However this only works for v4 sockets. Considering things are moving to
IPv6 heavily (especially within enterprise networks), ZMQ should support setting
`traffic class` for v6 based on `ZMQ_TOS`.

There is a subtle difference between v4 and v6 in terms of the positioning of
field but TOS has same meaning in both v4 and v6. Linux provides following APIs
for v4/v6 to set TOS field value.
```
// For v4
setsockopt(fd, IPPROTO_IP, IP_TOS, tos, sizeof(tos));

// For v6
setsockopt(fd, IPPROTO_IPV6, IPV6_TCLASS, tos, sizeof(tos));
```

Test Plan:
Make sure Cmake works fine and all tests passes.
Imported this change to `OpenR` project and tested on our local testbed.
Captured some packets exchanged between PUB/SUB and ROUTER/ROUTER sockets
pairs. Verify that `TCLASS` value is set as per expectation.

Tasks: #2208

1b3fcbd3ee Problem: linker fails looking for dladdr 
Solution: search and add it via AC_CHECK_LIB when building with
libunwind, as the backtrace function uses dladdr. This problem
only appears on some distributions and with some compiler/toolchain
versions.

213a7efe86 Problem: curve_keygen not build unless --enable-curve is passed 
Solution: test ENABLE_CURVE_KEYGEN and enable it only if
zmq_enable_curve_keygen=yes nad enable_curve=yes. Additionally set
enable_curve=yes for libsodium and tweetnacl, so it is enabled
implicitly and fixes the problem.

This block of code will either return -1 or fall through.
The while (true) does nothing.

Solution: try to detect architecture if building with VC++ and
hardcode pointer size accordingly.
Expressions are not allowed inside declspec intrinsics, which
includes other intrinsics.

df367a6682 Problem: pointer union for zmq_msg_t is a hack 
Solution: use compiler's alignment attributes instead which is
clearer and less of a hack.
Pointer alignment violations causing crashes on architectures
such as sparc64 and aarch64.
This also avoid triggering ABI checkers as the change is compatible
even though applications that suffer from the bug should rebuild to
take advantage of the fix.

clock_gettime is now defined in macOS 10.12 SDK
 2016-10-28 11:29:58 +01:00
Robert Castle
0dfb32a259 Problem: clock_gettime is now defined in macOS 10.12 SDK 
Solution: Rename the custom implementation of clock_gettime for macOS to
alt_clock_gettime and wrap all usage in preprocessor macros to only enable the
alternative version when using macOS <= 10.11.

This issue occurs when targeting macOS 10.11 or earlier but using the 10.12
or newer SDK.
