0MQ version 4.3.5 stable, released on 2023/10/09
* Relicensing from LGPL-3.0+ (with custom exceptions) to MPL-2.0 is now complete.
libzmq is now distributed under the Mozilla Public License 2.0. Relicensing
grants have been collected from all relevant authors, and some functionality
has been clean-room reimplemented where that was not possible. In layman terms,
the new license provides the same rights and obligations as before. Source
files are now tagged using the SPDX license identifier format.
Details of the relicensing process can be seen at:
#2376
Relicensing grants have been archived at:
https://github.com/rlenferink/libzmq-relicense
A special thanks to everybody who helped with this long and difficult task,
with the process, the reimplementations, the collections and everything else.
* New DRAFT (see NEWS for 4.2.0) socket options:
+ ZMQ_BUSY_POLL will set the SO_BUSY_POLL socket option on the underlying
sockets, if it is supported.
+ ZMQ_HICCUP_MSG will send a message when the peer has been disconnected.
+ ZMQ_XSUB_VERBOSE_UNSUBSCRIBE will configure a socket to pass all
unsubscription messages, including duplicated ones.
+ ZMQ_TOPICS_COUNT will return the number of subscribed topics on a
PUB/SUB socket.
+ ZMQ_NORM_MODE, ZMQ_NORM_UNICAST_NACK, ZMQ_NORM_BUFFER_SIZE,
ZMQ_NORM_SEGMENT_SIZE, ZMQ_NORM_BLOCK_SIZE, ZMQ_NORM_NUM_PARITY,
ZMQ_NORM_NUM_AUTOPARITY and ZMQ_NORM_PUSH to control various aspect of
NORM sockets.
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New DRAFT (see NEWS for 4.2.0) zmq_ppoll APIs was added that differs from
zmq_poll in the same way that ppoll differs from poll.
See doc/zmq_ppoll.txt for details.
* Various bug fixes and performance improvements.

0MQ version 4.3.3 stable, released on 2020/09/07
* Security advisories:
+ CVE-2020-15166: Denial-of-Service on CURVE/ZAP-protected servers by
unauthenticated clients.
If a raw TCP socket is opened and connected to an endpoint that is fully
configured with CURVE/ZAP, legitimate clients will not be able to exchange
any message. Handshakes complete successfully, and messages are delivered to
the library, but the server application never receives them.
For more information see the security advisory:
GHSA-25wp-cf8g-938m
+ Stack overflow on server running PUB/XPUB socket (CURVE disabled).
The PUB/XPUB subscription store (mtrie) is traversed using recursive
function calls. In the remove (unsubscription) case, the recursive calls are
NOT tail calls, so even with optimizations the stack grows linearly with the
length of a subscription topic. Topics are under the control of remote
clients - they can send a subscription to arbitrary length topics. An
attacker can thus cause a server to create an mtrie sufficiently large such
that, when unsubscribing, traversal will cause a stack overflow.
For more information see the security advisory:
GHSA-qq65-x72m-9wr8
+ Memory leak in PUB server induced by malicious client(s) without CURVE/ZAP.
Messages with metadata are never processed by PUB sockets, but the metadata
is kept referenced in the PUB object and never freed.
For more information see the security advisory:
GHSA-4p5v-h92w-6wxw
+ Memory leak in client induced by malicious server(s) without CURVE/ZAP.
When a pipe processes a delimiter and is already not in active state but
still has an unfinished message, the message is leaked.
For more information see the security advisory:
GHSA-wfr2-29gj-5w87
+ Heap overflow when receiving malformed ZMTP v1 packets (CURVE disabled).
By crafting a packet which is not valid ZMTP v2/v3, and which has two
messages larger than 8192 bytes, the decoder can be tricked into changing
the recorded size of the 8192 bytes static buffer, which then gets overflown
by the next message. The content that gets written in the overflown memory
is entirely decided by the sender.
For more information see the security advisory:
GHSA-fc3w-qxf5-7hp6
* Note for packagers: an external, self-contained sha1 library is now
included in the source tree under external/sha1/ - it is licensed
under BSD-3-Clause and thus it is fully compatible with libzmq's
license.
It is only used if WebSockets support is enabled, and if neither GnuTLS nor
NSS are available.
* Note for packagers: an internal reimplementation of strlcpy is now included,
for wider platform compatibility.
libbsd can be used and is enabled by default if available instead of the
internal implementation, for better security maintenance in distros.
* Note for packagers: ZeroMQConfig.cmake is now installed in the arch-dependent
subdirectory - eg: /usr/lib/x86_64-linux-gnu/cmake/
* New DRAFT (see NEWS for 4.2.0) socket type:
+ ZMQ_CHANNEL is a thread-safe alternative to ZMQ_PAIR.
See doc/zmq_socket.txt for details.
* New DRAFT (see NEWS for 4.2.0) socket option:
+ ZMQ_ONLY_FIRST_SUBSCRIBE will cause only the first part of a multipart
message to be processed as a subscribe/unsubscribe message, and the rest
will be forwarded as user data to the application.
+ ZMQ_RECONNECT_STOP will cause a connecting socket to stop trying to
reconnect in specific circumstances. See the manpage for details.
+ ZMQ_HELLO_MSG to set a message that will be automatically sent to a new
connection.
+ ZMQ_DISCONNECT_MSG to set a message that will be automatically received when
a peer disconnects.
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New DRAFT (see NEWS for 4.2.0) zmq_ctx_get_ext/zmq_ctx_set_ext APIs were added
to allow enhancing the context options with variable data inputs.
See doc/zmq_ctx_get_ext.txt and doc/zmq_ctx_set_ext.txt for details.
* New DRAFT (see NEWS for 4.2.0) transport options WS and WSS added for support
of WebSockets (and secure WebSockets via TLS) via the ZWS 2.0 protocol.
WSS requires the GnuTLS library for TLS support. ZMQ_WSS_ specific socket
options were added to support TLS.
WebSockets support is disabled by default if DRAFT APIs are disabled.
* New DRAFT (see NEWS for 4.2.0) socket type, PEER, which is thread safe and a
related zmq_connect_peer function which atomically and thread-safely connects
and returns a routing-id.
* New DRAFT (see NEWS for 4.2.0) zmq_msg_init_buffer API was added to allow
the construction of a message by copying from an existing buffer.
* New DRAFT (see NEWS for 4.2.0) zmq_poller_size API was added to allow querying
the number of sockets/fds registered in a zmq_poller.
* ZMTP 3.1 peers will receive subscribe/cancel on PUB/SUB via commands rather
than using the first byte of the payload.
* zmq_z85_decode now checks that the input string's length is at least 5 characters
and always a multiple of 5 as per API specification.
* Fixed #3566 - malformed CURVE message can cause memory leak
* Fixed #3567 - missing ZeroMQ_INCLUDE_DIR in ZeroMQConfig.cmake when only
static lib is built
* Fixed #3576 - CURVE plaintext secrets now stored in libsodium's secure memory

0MQ version 4.3.2 stable, released on 2019/07/08
* CVE-2019-13132: a remote, unauthenticated client connecting to a
libzmq application, running with a socket listening with CURVE
encryption/authentication enabled, may cause a stack overflow and
overwrite the stack with arbitrary data, due to a buffer overflow in
the library. Users running public servers with the above configuration
are highly encouraged to upgrade as soon as possible, as there are no
known mitigations. All versions from 4.0.0 and upwards are affected.
Thank you Fang-Pen Lin for finding the issue and reporting it!
* New DRAFT (see NEWS for 4.2.0) zmq_socket_monitor_versioned API that supports
a versioned monitoring events protocol as a parameter. Passing 1 results in
the same behaviour as zmq_socket_monitor.
Version 2 of the events protocol allows new events, new metadata, different
socket types for the monitors and more. It is described in details in
doc/zmq_socket_monitor_versioned.txt
* New DRAFT (see NEWS for 4.2.0) zmq_socket_monitor_pipes_stats that triggers
a new ZMQ_EVENT_PIPES_STATS to be delivered via zmq_socket_monitor_versioned
v2 API, which contains the current status of all the queues owned by the
monitored socket. See doc/zmq_socket_monitor_versioned.txt for details.
* New DRAFT (see NEWS for 4.2.0) zmq_poller_fd that returns the FD of a thread
safe socket. See doc/zmq_poller.txt for details.
* New DRAFT (see NEWS for 4.2.0) socket options:
+ ZMQ_XPUB_MANUAL_LAST_VALUE is similar to ZMQ_XPUB_MANUAL but allows to avoid
duplicates when using last value caching.
+ ZMQ_SOCKS_USERNAME and ZMQ_SOCKS_PASSWORD that implement SOCKS5 proxy
authentication.
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* Implemented background thread names for Windows, when the Visual Studio
debugger is being used.
* Fixed #3358 - test_security_zap failing due to SIGBUS on SPARC64, hard-coded
IPC socket binds in tests cause race conditions
* Fixed #3361 - enabling GSSAPI support (when using autools) does not work due
to regression introduced in 4.2.3
* Fixed #3362 - remove documentation for ZMQ_THREAD_PRIORITY context option
getter, it's not implemented
* Fixed #3363 - tests fail to build due to stricter compiler printf validation
in new versions of GCC
* Fixed #3367 - try to infer cacheline size at build time, first with
getconf LEVEL1_DCACHE_LINESIZE, and then by reading
/sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size
(autoconf only), and only then falling back to the previous
default of 64 bytes. Avoids false sharing on POWER and s390x.
Import ax_func_posix_memalign.m4 as a more reliable check for
posix_memalign presence on some unix platforms.
Prefer c++11 atomic primitives to compiler intrinsics, when
both are available, as the former is more reliable.
Set test_pair_ipc and test_rebind_ipc to XFAIL on GNU/Hurd due
to non-functioning getsockname on AF_UNIX.
* Fixed #3370 - Make queue length and HWM state observable
* Fixed #3373 - performance regression in zmq_poll on CentOS 6/7
* Fixed #3375 - assign names to all pthreads created by the library to ease
debugging
* Fixed #3376 - assigned random TIPC port is not returned by ZMQ_LAST_ENDPOINT
* Fixed #3385 - TCP port in ZMQ_LAST_ENDPOINT depends on global locale
* Fixed #3404 - use std::condition_variable_any when possible
* Fixed #3436 - reconnect interval exponential backoff and may lead to integer
overflows
* Fixed #3440 - improve zmq_proxy performance by batching of up to 1000
consecutive messages (if any) and add perf/proxy_thr tool
* Fixed #3451 - fix support of /dev/poll on Solaris
* Fixed #3452 - strnlen may not be available
* Fixed #1462 - test failure in test_filter_ipc due to invalid system groups
* Fixed #3269 - Boost.ASIO integration stopped working with v4.3.0
* Fixed #3479 - ZeroMQ does not build for QNX 6.6 with CMake
* Fixed #3481 - add include to fix uClibc++ compilation
* Fixed #3491 - build broken on Fedora 30
* Fixed #3494 - ZeroMQConfig.cmake fails if shared libraries are not built
* Fixed #3498 - syntax error on Windows related to socket descriptor type
* Fixed #3500 - PLAIN HELLO message incorrectly uses WELCOME literal, regression
introduced in 4.3.0
* Fixed #3517 - configure errors because of syntax errors in the use of test
shell command
* Fixed #3521 - document how to achieve high performance with the PGM transport
* Fixed #3526 - failure case behavior unclear in zmq_msg_send documentation
* Fixed #3537 - fix build on z/OS by using pthread_equal instead of comparing
variables directly
* Fixed #3546 - CMake links with librt on MinGW which is not available
* Many coding style, duplication, testing and static analysis improvements.

0MQ version 4.3.1 stable, released on 2019/01/12
* CVE-2019-6250: A vulnerability has been found that would allow attackers to direct a peer to
jump to and execute from an address indicated by the attacker.
This issue has been present since v4.2.0. Older releases are not affected.
NOTE: The attacker needs to know in advance valid addresses in the peer's
memory to jump to, so measures like ASLR are effective mitigations.
NOTE: this attack can only take place after authentication, so peers behind
CURVE/GSSAPI are not vulnerable to unauthenticated attackers.
See #3351 for more details.
Thanks to Guido Vranken for uncovering the issue and providing the fix!
* Note for packagers: as pkg-config's Requires.private is now used to properly
propagate dependencies for static builds, the libzmq*-dev or zeromq-devel or
equivalent package should now depend on the libfoo-dev or foo-devel packages
of all the libraries that zmq is linked against, or pkg-config --libs libzmq
will fail due to missing dependencies on end users machines.
* Fixed #3351 - remote code execution vulnerability.
* Fixed #3343 - race condition in ZMQ_PUSH when quickly disconnecting and
reconnecting causes last part of multi-part message to get
"stuck" and resent by mistake to the new socket.
* Fixed #3336 - set Requires.private in generate pkg-config file.
* Fixed #3334 - set TCP_NODELAY after connect() on Windows for the I/O socket.
* Fixed #3326 - assert on Android when opening a socket and disabling WiFi.
* Fixed #3320 - build failure on OpenBSD with GCC.

0MQ version 4.3.0 stable, released on 2018/11/28
* The following DRAFT APIs have been marked as STABLE and will not change
anymore:
+ ZMQ_MSG_T_SIZE context option (see doc/zmq_ctx_get.txt)
+ ZMQ_THREAD_AFFINITY_CPU_ADD and ZMQ_THREAD_AFFINITY_CPU_REMOVE (Posix only)
context options, to add/remove CPUs to the affinity set of the I/O threads.
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
+ ZMQ_THREAD_NAME_PREFIX (Posix only) context option, to add a specific
integer prefix to the background threads names, to easily identify them.
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
+ ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE
socket options, for the corresponding GSSAPI features. Additional
definitions for principal name types:
o ZMQ_GSSAPI_NT_HOSTBASED
o ZMQ_GSSAPI_NT_USER_NAME
o ZMQ_GSSAPI_NT_KRB5_PRINCIPAL
See doc/zmq_gssapi.txt for details.
+ ZMQ_BINDTODEVICE socket option (Linux only), which will bind the
socket(s) to the specified interface. Allows to use Linux VRF, see:
https://www.kernel.org/doc/Documentation/networking/vrf.txt
NOTE: requires the program to be ran as root OR with CAP_NET_RAW
+ zmq_timers_* APIs. These functions can be used for cross-platforms timed
callbacks. See doc/zmq_timers.txt for details.
+ The following socket monitor events:
o ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL: unknown errors during handshake.
o ZMQ_EVENT_HANDSHAKE_SUCCEEDED: Handshake completed with authentication.
o ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL: Protocol errors with peers or ZAP.
o ZMQ_EVENT_HANDSHAKE_FAILED_AUTH: Failed authentication requests.
See doc/zmq_socket_monitor.txt for more details and error codes.
+ zmq_stopwatch_intermediate which returns the time elapsed without stopping
the stopwatch.
+ zmq_proxy_steerable command 'STATISTICS' to retrieve stats about the amount
of messages and bytes sent and received by the proxy.
See doc/zmq_proxy_steerable.txt for more information.
* The build-time configuration option to select the poller has been split, and
new API_POLLER (CMake) and --with-api-poller (autoconf) options will now
determine what system call is used to implement the zmq_poll/zmq_poller APIs.
The previous POLLER and --with-poller options now only affects the
internal I/O thread. In case API_POLLER is not specified, the behaviour keeps
backward compatibility intact and will be the same as with previous releases.
* The non-default "poll" poller for the internal I/O thread (note: NOT for the
zmq_poll/zmq_poller user APIs!) has been disabled on Windows as WSAPoll does
not report connection failures. For more information see:
+ https://daniel.haxx.se/blog/2012/10/10/wsapoll-is-broken/
+ https://curl.haxx.se/mail/lib-2012-10/0038.html
+ https://bugs.python.org/issue16507
* New epoll implementation for Windows, using the following implementation:
https://github.com/piscisaureus/wepoll/tree/v1.5.4
To use this, select "epoll" as the poller option in the build system.
Note for distributors: the wepoll source code is embedded and distributed.
It is licensed under the BSD-2-Clause and thus it is compatible with LGPL-3.0.
Note that, if selected at build time, the license text must be distributed
with the binary in accordance to the license terms. A copy can be found at:
external/wepoll/license.txt
* The pre-made Visual Studio solutions file are deprecated, and users are
encouraged to use the CMake solution generation feature instead.
* New DRAFT (see NEWS for 4.2.0) socket options:
+ ZMQ_ROUTER_NOTIFY to deliver a notification when a peer connects and/or
disconnects in the form of a routing id plus a zero-length frame.
+ ZMQ_MULTICAST_LOOP to control whether the data sent should be looped back
on local listening sockets for UDP multicast sockets (ZMQ_RADIO).
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New perf tool, perf/benchmark_radix_tree, to measure the performance of the
different internal implementations of the trie algorithm used to track
subscriptions. Requires a compiler that supports C++11.
* New autoconf flag "--enable-force-CXX98-compat" which will force -std=gnu++98
and, if the compiler supports them (clang++ at the moment), it will also add
-Wc++98-compat -Wc++98-compat-pedantic so that compatibility with C++98 can
be tested.
* Many, many coding style, duplication and static analysis improvements.
* Many, many improvements to the CMake build system, especially on Windows.

* Fixed #3085 - autoconf/CMake getrandom test does not check if it's working but
only for its presence.
* Fixed #3090 - compilation broken with Solaris Studio.
* Fixed #3094 - UDP: pass interface via IP[V6]_MULTICAST_IF if provided.

0MQ version 4.2.3 stable, released on 2017/12/13
* API change: previously ZMQ_POLLOUT on a ZMQ_ROUTER socket returned always
true due to how the type works. When ZMQ_ROUTER_MANDATORY is set, sending
fails when the peer is not available, but ZMQ_POLLOUT always returns true
anyway, which does not make sense. Now when ZMQ_ROUTER_MANDATORY is set,
ZMQ_POLLOUT on a ZMQ_ROUTER will return true only if at least one peer is
available.
Given ZMQ_POLLOUT with ZMQ_ROUTER was not usable at all previously, we do
not consider this a breakage warranting a major or minor version increase.
* ZMQ_IDENTITY has been renamed to ZMQ_ROUTING_ID and ZMQ_CONNECT_RID has been
renamed to ZMQ_CONNTECT_ROUTING_ID to disambiguate. ZMQ_IDENTITY and
ZMQ_CONNECT_RID are still available to keep backward compatibility, and will
be removed in a future release after further advance notice.
* DRAFT API change: zmq_poller_wait, zmq_poller_wait_all and zmq_poller_poll
have been changed to be inline with other existing APIs that have a timeout
to return EAGAIN instead of ETIMEDOUT as the errno value.
See #2713 for details.
* Existing non-DRAFT socket types ZMQ_REP/REQ, ZMQ_ROUTER/DEALER and
ZMQPUB/SUB, that were previously declared deprecated, have been reinstated
as stable and supported. See #2699 for details.
* Tweetnacl: add support for, and use preferably if available, getrandom() as
a simpler and less error-prone alternative to /dev/urandom on OSes where it
is available (eg: Linux 3.18 with glibc 2.25).
* Curve: all remaining traces of debug output to console are now removed, and
new DRAFT events are available to properly debug CURVE, PLAIN, GSSAPI and
ZAP events and failures. See below for details on the new events.
* New DRAFT (see NEWS for 4.2.0) socket options:
+ ZMQ_GSSAPI_PRINCIPAL_NAMETYPE and ZMQ_GSSAPI_SERVICE_PRINCIPAL_NAMETYPE, for
the corresponding GSSAPI features. Additional definitions for principal
name types:
o ZMQ_GSSAPI_NT_HOSTBASED
o ZMQ_GSSAPI_NT_USER_NAME
o ZMQ_GSSAPI_NT_KRB5_PRINCIPAL
See doc/zmq_gssapi.txt for details.
+ ZMQ_BINDTODEVICE (Linux only), which will bind the socket(s) to the
specified interface. Allows to use Linux VRF, see:
https://www.kernel.org/doc/Documentation/networking/vrf.txt
NOTE: requires the program to be ran as root OR with CAP_NET_RAW
+ ZMQ_ZAP_ENFORCE_DOMAIN, enables strict RFC 27 compatibility mode and makes
the ZAP Domain mandatory when using security. See:
https://rfc.zeromq.org/spec:27/ZAP
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
* New DRAFT (see NEWS for 4.2.0) context options:
+ ZMQ_THREAD_AFFINITY_CPU_ADD and ZMQ_THREAD_AFFINITY_CPU_REMOVE (Posix only),
to add and remove CPUs to the affinity set of the I/O threads. Useful to pin
the background threads to specific CPUs.
+ ZMQ_THREAD_NAME_PREFIX (Posix only), to add a specific integer prefix to the
background threads names, to easily identify them for debugging purposes.
See doc/zmq_ctx_set.txt and doc/zmq_ctx_get.txt for details.
* New DRAFT (see NEWS for 4.2.0) message property name definitions to facilitate
the use of zmq_msg_gets:
+ ZMQ_MSG_PROPERTY_ROUTING_ID
+ ZMQ_MSG_PROPERTY_SOCKET_TYPE
+ ZMQ_MSG_PROPERTY_USER_ID
+ ZMQ_MSG_PROPERTY_PEER_ADDRESS
See doc/zmq_msg_gets.txt for details.
* New DRAFT (see NEWS for 4.2.0) API zmq_socket_get_peer_state, to be used to
query the state of a specific peer (via routing-id) of a ZMQ_ROUTER socket.
* New DRAFT (see NEWS for 4.2.0) Socket Monitor events:
+ ZMQ_EVENT_HANDSHAKE_FAILED_NO_DETAIL, unknown system error and returns errno
+ ZMQ_EVENT_HANDSHAKE_SUCCEEDED, handshake was successful
+ ZMQ_EVENT_HANDSHAKE_FAILED_PROTOCOL, protocol errors between peers or server
and ZAP handler. Returns one of ZMQ_PROTOCOL_ERROR_* - see manpage for list
+ ZMQ_EVENT_HANDSHAKE_FAILED_AUTH, failed authentication, returns ZAP status
These events trigger when the ZMTP security mechanism handshake is
completed or failed. See doc/zmq_socket_monitor.txt for more information.
* New DRAFT (see NEWS for 4.2.0) zmq_proxy_steerable command 'STATISTICS' to
retrieve stats about the amount of messages and bytes sent and received by
the proxy. See doc/zmq_proxy_steerable.txt for more information.
* Add new autoconf --disable-libunwind option to stop building with libunwind
even if it is available.
* Add new autoconf --disable-Werror option to avoid building with the Werror
flag.
* Use pkg-config as the first method for finding and building with external
optional dependencies such as libnorm, libpgm and gssapi.
* On Posix platform where the feature is available, name the ZMQ background
threads to simplify debugging: "ZMQbg/<num_thread>"
* Improve performance of zmq_poller_* (and zmq_poll and zmq_proxy when building
with DRAFT APIs enabled).
* The TCP unit tests have been refactored to bind and connect to random ports
rather than hard-coded ones, to allow running tests in parallel.
There are 6 exceptions where it is necessary to use an hard-coded port to
test specific code paths that would not be exercised when binding to a
wildcard port. These are listed in tests/testutil.hpp so that distributions
can easily patch them if they wish to and so that they can be unique across
all the tests, allowing parallel runs.
The IPC unit tests have been changed as well to use unique socket file names
per test, where before there were some clashes.
* Fixed #2349 - fix building with libsodium when using CMake
* Fixed #2334 - do not assert when tuning socket options fails due to network
errors, but simply retry again when connecting or send a socket monitor

implementation) instead of Libsodium, and fix race condition when using
multiple ZMQ contexts with Tweetnacl
