Solution: detect cacheline size for aligment purposes at build time
instead of hard-coding it, so that PPC and S390 can align to a value
greater than the 64 bytes default.
Uses libc getconf program, and falls back to the previous value of 64
if not found.
Solution: use requires.private, which pkg-config expands recursively
so that dependencies of dependencies can be linked against when
using pkg-config --static
Solution: go back to using -Wl,--version-script.
Use ax_check_vscript.m4 from the autoconf-archive to detect support on
multiple platforms (eg Solaris ld(1) -M).
libtool -export-symbols-regexp used ld(1) --retain-symbols-file under
the hood, the latter lets some C++ weak symbols make their way into the
dynamic symbols table, along with the zmq_* interface. The reason for
such behavior is unknown to me.
Solution: if the compiler supports it, pass C++98-compat flags.
Currently Clang supports this flag but GCC does not.
Add a new flag to enable it, as building with C++98-compat but also
with -std=gnu++11 will cause a lot of warnings due to the backward
compat ifdefs.
Add a CI job to run it and ensure we don't break compatibility.
Solution: ignore tautological-constant-compare warnings, as they
might be useless on 64 bit but they are not on 32 bit where sizeof
size_t != sizeof uint64_t
The original configure.ac tries to check for dladdr, but it actually needs
it only in case we have libunwind (which has a another section and checks for it
too).
This can fail the build on systems without dynamic linking support.
Therefore, the dladdr check has to be preformed only when checking libunwind.

Solution: revert DRAFT -> STABLE API transition so that we can do a
bugfix-only 4.2.5 release.
Will be re-reverted once tagged.
Revert "Problem: ZMQ_BINDTODEVICE has met STABLE conditions"
This reverts commit 3cb79f5042.
Revert "Problem: ZMQ_MSG_GSSAPI_* have met STABLE conditions"
This reverts commit 374da4207b.
Revert "Problem: ZMQ_MSG_T_SIZE has met STABLE conditions"
This reverts commit 6411c4a247.
Revert "Problem: docs say STABLE API still in DRAFT"
This reverts commit 9f2f30b7ff.
Solution: move it from DRAFT to STABLE since it's been in a public
release, committed for 6+ months and has not changed.
Given a new STABLE symbol has been added, bump minor version number.
* Problem: TIPC availability check is too strict
Solution: at build time only check if the API is available. In the tests
do a first check and a skip if the functionality is not available.
TIPC needs an in-tree but not loaded by default kernel module, tipc.ko
to be loaded, which requires root, so it is unlikely to be available on
any build system by default.
This will allow most distributions to ship with TIPC support built in,
and to avoid tests failure if the module is not there.
* Problem: no Travis tests for TIPC
Solution: mark one job with sudo: required and load the kernel module
* Problem: CMake fails when test returns 77 (skip)
Solution: set property to let it mark the test as skipped as intended
* Background thread scheduling
- add ZMQ_THREAD_AFFINITY ctx option; set all thread scheduling options
from the context of the secondary thread instead of using the main
process thread context!
- change ZMQ_THREAD_PRIORITY to support setting NICE of the background
thread when using SCHED_OTHER
* Extracted connect_vanilla_socket function
* Problem: no tests for ZMTP-CURVE protocol errors
Solution: added two test cases with erroneous HELLO commands
* Problem: insufficient tests for ZMTP-CURVE protocol errors
Solution: added two test cases with erroneous HELLO command version
* Problem: test HELLO message is invalid apart from deliberate errors
Solution: create cryptographically correct HELLO message
add tweetnacl.c to test_security_curve
* Problem: nonce is incorrect, build fails with GCC
Solution: use correct non prefix
* Problem: make builds are failing
Solution: transfer CMake changes to (auto)make files
* Problem: nonce is incorrect, build fails with GCC
Solution: use correct non prefix
* Problem: make builds are failing
Solution: transfer CMake changes to (auto)make files
* Problem: no test with INITIATE command with invalid length
Solution: added test case
* Problem: code duplication between test_security_curve.cpp and curve_client.cpp
Solution: extracted parts of zmq::curve_client_t::produce_hello into reusable function
* Problem: code duplication between test_security_curve.cpp and curve_client.cpp
Solution: extracted further parts of zmq::curve_client_t into reusable functions
added missing file
* Problem: mechanism_t::add_property can be declared static
Solution: declare mechanism_t::add_property static
* Problem: intermediate crypto data needs to be passed between static function calls to curve_client_tools_t
Solution: add non-static member functions
* Problem: msg_t instance may be closed twice
Solution: remove offending close
* Problem: prepare_hello uses static curve_client_tools_t::produce_hello
Solution: Use non-static curve_client_tools_t::produce_hello
* Problem: no test with invalid command name where INITIATE command is expected
Solution: added test case
* Problem: make builds are failing due to curve_client_tools.hpp not being found
Solution: add curve_client_tools.hpp to list of source files
* Problem: wrong initializer order in zmq::curve_client_t
Solution: reorder
* Problem: under non-Windows systems, test fails because random_open was not called
Solution: call random_open/random_close within test
* Problem: conflict between custom function htonll and macro definition on Darwin
Solution: define htonll function only if not defined as a macro
* Problem: nullptr not defined on all platforms
Solution: replace nullptr by NULL
* Problem: libsodium builds not working
Solution: adapt compile and link file sets for libsodium builds
* Problem: Makefile.am broken
Solution: Fix syntax
* Problem: no tests for garbage encrypted cookie or content in INITIATE
Solution: added test cases
* Problem: test cases accidentally excluded from build
Solution: remove #if/#endif
* Solution: some error cases are unreachable
Problem: for the time being, added some comments without changing the code
* Added comments on hard-to-test cases
Linux now supports Virtual Routing and Forwarding (VRF) as per:
https://www.kernel.org/doc/Documentation/networking/vrf.txt
In order for an application to bind or connect to a socket with an
address in a VRF, they need to first bind the socket to the VRF device:
setsockopt(sd, SOL_SOCKET, SO_BINDTODEVICE, dev, strlen(dev)+1);
Note "dev" is the VRF device, eg. VRF "blue", rather than an interface
enslaved to the VRF.
Add a new socket option, ZMQ_BINDTODEVICE, to bind a socket to a device.
In general, if a socket is bound to a device, eg. an interface, only
packets received from that particular device are processed by the socket.
If device is a VRF device, then subsequent binds/connects to that socket
use addresses in the VRF routing table.
on ia64 architecture libunwind comes with gcc. Unfortunately
libunwind is not directly usable as-is and fails at link time:
```
ia64-unknown-linux-gnu-g++ -o perf/.libs/local_lat perf/local_lat.o src/.libs/libzmq.so -lsodium -lrt -lpthread -ldl
src/.libs/libzmq.so: undefined reference to `_ULia64_step'
```
The change adds --{enable,disable}-libunwind flag to control
automatic dependency. The default is unchanged: use if available.
