+Subject: [PATCH 1/4] BUG/MAJOR: fix listening IP address storage for frontends
+
+When compiled with GCC 6, the IP address specified for a frontend was
+ignored and HAProxy was listening on all addresses instead. This is
+caused by an incomplete copy of a "struct sockaddr_storage".
+
+With the GNU Libc, "struct sockaddr_storage" is defined as this:
+
+ struct sockaddr_storage
+ {
+ sa_family_t ss_family;
+ unsigned long int __ss_align;
+ char __ss_padding[(128 - (2 * sizeof (unsigned long int)))];
+ };
+
+Doing an aggregate copy (ss1 = ss2) is different than using memcpy():
+only members of the aggregate have to be copied. Notably, padding can be
+or not be copied. In GCC 6, some optimizations use this fact and if a
+"struct sockaddr_storage" contains a "struct sockaddr_in", the port and
+the address are part of the padding (between sa_family and __ss_align)
+and can be not copied over.
+
+Therefore, we replace any aggregate copy by a memcpy(). There is another
+place using the same pattern. We also fix a function receiving a "struct
+sockaddr_storage" by copy instead of by reference. Since it only needs a
+read-only copy, the function is converted to request a reference.
+
+This is a backport for 1.5 of 6e6158 and 6e46ff1.

-Subject: [PATCH 06/26] MEDIUM: make SO_REUSEPORT configurable
-
-With Linux officially introducing SO_REUSEPORT support in 3.9 and
-its mainstream adoption we have seen more people running into strange
-SO_REUSEPORT related issues (a process management issue turning into
-hard to diagnose problems because the kernel load-balances between the
-new and an obsolete haproxy instance).
-
-Also some people simply want the guarantee that the bind fails when
-the old process is still bound.
-
-This change makes SO_REUSEPORT configurable, introducing the command
-line argument "-dR" and the noreuseport configuration directive.
-
-A backport to 1.6 should be considered.

-Subject: [PATCH 16/26] BUG/MEDIUM: systemd: let the wrapper know that haproxy
- has completed or failed
-
-Pierre Cheynier found that there's a persistent issue with the systemd
-wrapper. Too fast reloads can lead to certain old processes not being
-signaled at all and continuing to run. The problem was tracked down as
-a race between the startup and the signal processing : nothing prevents
-the wrapper from starting new processes while others are still starting,
-and the resulting pid file will only contain the latest pids in this
-case. This can happen with large configs and/or when a lot of SSL
-certificates are involved.
-
-In order to solve this we want the wrapper to wait for the new processes
-to complete their startup. But we also want to ensure it doesn't wait for
-nothing in case of error.
-
-The solution found here is to create a pipe between the wrapper and the
-sub-processes. The wrapper waits on the pipe and the sub-processes are
-expected to close this pipe once they completed their startup. That way
-we don't queue up new processes until the previous ones have registered
-their pids to the pid file. And if anything goes wrong, the wrapper is
-immediately released. The only thing is that we need the sub-processes
-to know the pipe's file descriptor. We pass it in an environment variable
-called HAPROXY_WRAPPER_FD.
-
-It was confirmed both by Pierre and myself that this completely solves
-the "zombie" process issue so that only the new processes continue to
-listen on the sockets.
-
-It seems that in the future this stuff could be moved to the haproxy
-master process, also getting rid of an environment variable.
-
-This fix needs to be backported to 1.6 and 1.5.

-Subject: [PATCH 25/26] BUG/MEDIUM: peers: on shutdown, wake up the appctx, not
- the stream
-
-This part was missed when peers were ported to the new applet
-infrastructure in 1.6, the main stream is woken up instead of the
-appctx. This creates a race condition by which it is possible to
-wake the stream at the wrong moment and miss an event. This bug
-might be at least partially responsible for some of the CLOSE_WAIT
-that were reported on peers session upon reload in version 1.6.
-
-This fix must be backported to 1.6.

-Subject: [PATCH 26/26] BUG/MEDIUM: peers: fix use after free in
- peer_session_create()
-
-In case of resource allocation error, peer_session_create() frees
-everything allocated and returns a pointer to the stream/session that
-was put back into the free pool. This stream/session is then assigned
-to ps->{stream,session} with no error control. This means that it is
-perfectly possible to have a new stream or session being both used for
-a regular communication and for a peer at the same time.
-
-In fact it is the only way (for now) to explain a CLOSE_WAIT on peers
-connections that was caught in this dump with the stream interface in
-SI_ST_CON state while the error field proves the state ought to have
-been SI_ST_DIS, very likely indicating two concurrent accesses on the
-same area :

-This fix must be backported to 1.6 and 1.5. Note that in 1.5 the
-session is not assigned from within the function so some extra checks
-may be needed in the callers.
