+    BUG/MEDIUM: servers: check the queues once enabling a server
+    
+    Commit 64cc49c ("MAJOR: servers: propagate server status changes
+    asynchronously.") heavily changed the way the server states are
+    updated since they became asynchronous. During this change, some
+    code was lost, which is used to shut down some sessions from a
+    backup server and to pick pending connections from a proxy once
+    a server is turned back from maintenance to ready state. The
+    effect is that when temporarily disabling a server, connections
+    stay in the backend's queue, and when re-enabling it, they are
+    not picked and they expire in the backend's queue. Now they're
+    properly picked again.
+    
+    This fix must be backported to 1.8.

+    BUG/MEDIUM: queue: prevent a backup server from draining the proxy's connections
+    
+    When switching back from a backup to an active server, the backup server
+    currently continues to drain the proxy's connections, which is a problem
+    because it's not expected to be able to pick them.
+    
+    This patch ensures that a backup server will only pick backend connections
+    if there is no active server and it is the selected backup server or all
+    backup servers are supposed to be used.
+    
+    This issue seems to have existed forever, so this fix should be backported
+    to all stable versions.

+    MINOR: dns: fix wrong score computation in dns_get_ip_from_response
+    
+    dns_get_ip_from_response() is used to compare the caller current IP to
+    the IP available in the records returned by the DNS server.
+    A scoring system is in place to get the best IP address available.
+    That said, in the current implementation, there are a couple of issues:
+    1. a comment does not match what the code does
+    2. the code does not match what the commet says (score value is not
+       incremented with '2')
+    
+    This patch fixes both issues.
+    
+    Backport status: 1.8

+    MINOR: dns: new DNS options to allow/prevent IP address duplication
+    
+    By default, HAProxy's DNS resolution at runtime ensure that there is no
+    IP address duplication in a backend (for servers being resolved by the
+    same hostname).
+    There are a few cases where people want, on purpose, to disable this
+    feature.
+    
+    This patch introduces a couple of new server side options for this purpose:
+    "resolve-opts allow-dup-ip" or "resolve-opts prevent-dup-ip".
+    
+    (cherry picked from commit 8e2d9430c0562ed74276d7f58e92706c384c0a36)
+    
+    [wt: this is backported to 1.8 upon request from Baptiste because it offers
+     the option to revert to 1.7 behaviour, which some people depend on. The

++    For such case, simply enable this option.
++    This is the opposite of prevent-dup-ip.
++
++  * prevent-dup-ip
++    Ensure HAProxy's default behavior is enforced on a server: prevent re-using
++    an IP address already set to a server in the same backend and sharing the
++    same fqdn.
++    This is the opposite of allow-dup-ip.

++  * If the nameserver returns 2 IP addresses, then each server will pick up a

+
+    BUG/MEDIUM: lua: possible CLOSE-WAIT state with '\n' headers
+    
+    The Lua parser doesn't takes in account end-of-headers containing
+    only '\n'. It expects always '\r\n'. If a '\n' is processes the Lua
+    parser considers it miss 1 byte, and wait indefinitely for new data.
+    
+    When the client reaches their timeout, it closes the connection.
+    This close is not detected and the connection keep in CLOSE-WAIT
+    state.
+    
+    I guess that this patch fix only a visible part of the problem.
+    If the Lua HTTP parser wait for data, the timeout server or the
+    connectio closed by the client may stop the applet.
+    
+    How reproduce the problem:
+    
+    HAProxy conf:
+    
+       global
+          lua-load bug38.lua
+       frontend frt
+          timeout client 2s
+          timeout server 2s
+          mode http
+          bind *:8080
+          http-request use-service lua.donothing
+    
+    Lua conf
+    
+       core.register_service("donothing", "http", function(applet) end)
+    
+    Client request:
+    
+       echo -ne 'GET / HTTP/1.1\n\n' | nc 127.0.0.1 8080
+    
+    Look for CLOSE-WAIT in the connection with "netstat" or "ss". I
+    use this script:
+    
+       while sleep 1; do ss | grep CLOSE-WAIT; done
+    
+    This patch must be backported in 1.6, 1.7 and 1.8
+    
+    Workaround: enable the "hard-stop-after" directive, and perform
+    periodic reload.

+    BUG/MEDIUM: threads: fix the double CAS implementation for ARMv7
+    
+    Commit f61f0cb ("MINOR: threads: Introduce double-width CAS on x86_64
+    and arm.") introduced the double CAS. But the ARMv7 version is bogus,
+    it uses the value of the pointers instead of dereferencing them. When
+    lucky, it simply doesn't build due to impossible registers combinations.
+    Otherwise it will immediately crash at run time when facing traffic.
+    
+    No backport is needed, this bug was introduced in 1.9-dev.

+
+    MINOR: threads: add more consistency between certain variables in no-thread case
+    
+    When threads are disabled, some variables such as tid and tid_bit are
+    still checked everywhere, the MAX_THREADS_MASK macro is ~0UL while
+    MAX_THREADS is 1, and the all_threads_mask variable is replaced with a
+    macro forced to zero. The compiler cannot optimize away all this code
+    involving checks on tid and tid_bit, and we end up in special cases
+    where all_threads_mask has to be specifically tested for being zero or
+    not. It is not even certain the code paths are always equivalent when
+    testing without threads and with nbthread 1.
+    
+    Let's change this to make sure we always present a single thread when
+    threads are disabled, and have the relevant values declared as constants
+    so that the compiler can optimize all the tests away. Now we have
+    MAX_THREADS_MASK set to 1, all_threads_mask set to 1, tid set to zero
+    and tid_bit set to 1. Doing just this has removed 4 kB of code in the
+    no-thread case.
+    
+    A few checks for all_threads_mask==0 have been removed since it never
+    happens anymore.
+    
+    (cherry picked from commit 0c026f49e7348bce5b3c74be896ae208ae6e26a4)
+    [wt: the thread code feels safer with this, especially with the small updates
+         needed for the rdv point; missed one occurrence fixed by next patch]

+    BUG/MEDIUM: threads: fix the no-thread case after the change to the sync point
+    
+    In commit 0c026f4 ("MINOR: threads: add more consistency between certain
+    variables in no-thread case"), we ensured that we don't have all_threads_mask
+    zeroed anymore. But one test was missed for the write() to the sync pipe.
+    This results in a situation where when running single-threaded, once a
+    server status changes, a wake-up message is written to the pipe and never
+    consumed, showing a 100% CPU usage.
+    
+    No backport is needed.

+
+    MEDIUM: hathreads: implement a more flexible rendez-vous point
+    
+    The current synchronization point enforces certain restrictions which
+    are hard to workaround in certain areas of the code. The fact that the
+    critical code can only be called from the sync point itself is a problem
+    for some callback-driven parts. The "show fd" command for example is
+    fragile regarding this.
+    
+    Also it is expensive in terms of CPU usage because it wakes every other
+    thread just to be sure all of them join to the rendez-vous point. It's a
+    problem because the sleeping threads would not need to be woken up just
+    to know they're doing nothing.
+    
+    Here we implement a different approach. We keep track of harmless threads,
+    which are defined as those either doing nothing, or doing harmless things.
+    The rendez-vous is used "for others" as a way for a thread to isolate itself.
+    A thread then requests to be alone using thread_isolate() when approaching
+    the dangerous area, and then waits until all other threads are either doing
+    the same or are doing something harmless (typically polling). The function
+    only returns once the thread is guaranteed to be alone, and the critical
+    section is terminated using thread_release().
+    
+    (cherry picked from commit 60b639ccbe919b86790267d7e45a39b75434acbe)

+
+    BUG/MEDIUM: cli: make "show fd" thread-safe
+    
+    The "show fd" command was implemented as a debugging aid but it's not
+    thread safe. Its features have grown, it can now dump some mux-specific
+    parts and is being used in production to capture some useful debugging
+    traces. But it will quickly crash the process when used during an H2 load
+    test for example, especially when haproxy is built with the DEBUG_UAF
+    option. It cannot afford not to be thread safe anymore. Let's make use
+    of the new rendez-vous point using thread_isolate() / thread_release()
+    to ensure that the data being dumped are not changing under us. The dump
+    becomes slightly slower under load but now it's safe.
+    
+    This should be backported to 1.8 along with the rendez-vous point code
+    once considered stable enough.

+    DOC: ssl: Use consistent naming for TLS protocols
+    
+    In most cases, "TLSv1.x" naming is used across and documentation, lazy
+    people tend to grep too much and may not find what they are looking for.
+    
+    Fixing people is hard.

+    BUG/MEDIUM: lua: socket timeouts are not applied
+    
+    Sachin Shetty reported that socket timeouts set in LUA code have no effect.
+    Indeed, connect timeout is never modified and is always set to its default,
+    set to 5 seconds. Currently, this patch will apply the specified timeout
+    value to the connect timeout.
+    For the read and write timeouts, the issue is that the timeout is updated but
+    the expiration dates were not updated.
+    
+    This patch should be backported up to the 1.6 branch.

+    
+    The proxy-related commands like "{enable|disable|shutdown} frontend",
+    "{enable|disable} dynamic-cookie", "set dynamic-cookie-key" were not
+    protected against concurrent accesses making their use dangerous with
+    threads.

+    BUG/MEDIUM: cli/threads: protect some server commands against concurrent operations
+    
+    The server-specific CLI commands "set weight", "set maxconn",
+    "disable agent", "enable agent", "disable health", "enable health",

+    BUG/MEDIUM: unix: provide a ->drain() function
+    
+    Right now conn_sock_drain() calls the protocol's ->drain() function if
+    it exists, otherwise it simply tries to disable polling for receiving
+    on the connection. This doesn't work well anymore since we've implemented
+    the muxes in 1.8, and it has a side effect with keep-alive backend
+    connections established over unix sockets. What happens is that if
+    during the idle time after a request, a connection reports some data,
+    si_idle_conn_null_cb() is called, which will call conn_sock_drain().
+    This one sees there's no drain() on unix sockets and will simply disable
+    polling for data on the connection. But it doesn't do anything on the
+    conn_stream. Thus while leaving the conn_fd_handler, the mux's polling
+    is updated and recomputed based on the conn_stream's polling state,
+    which is still enabled, and nothing changes, so we see the process
+    use 100% CPU in this case because the FD remains active in the cache.
+    
+    There are several issues that need to be addressed here. The first and
+    most important is that we cannot expect some protocols to simply stop
+    reading data when asked to drain pending data. So this patch make the
+    unix sockets rely on tcp_drain() since the functions are the same. This
+    solution is appropriate for backporting, but a better one is desired for
+    the long term. The second issue is that si_idle_conn_null_cb() shouldn't
+    drain the connection but the conn_stream.
+    
+    At the moment we don't have any way to drain a conn_stream, though a flag
+    on rcv_buf() will do it well. Until we support muxes on the server side
+    it is not a problem so this part can be addressed later.
+    
+    This fix must be backported to 1.8.

+
+    BUG/MINOR: lua: Bad HTTP client request duration.
+    
+    HTTP LUA applet callback should not update the date on which the HTTP client requests
+    arrive. This was done just after the LUA applet has completed its job.
+    
+    This patch simply removes the affected statement. The same fixe has been applied
+    to TCP LUA applet callback.
+    
+    To reproduce this issue, as reported by Patrick Hemmer, implement an HTTP LUA applet
+    which sleeps a bit before replying:
+    
+      core.register_service("foo", "http", function(applet)
+          core.msleep(100)
+          applet:set_status(200)
+          applet:start_response()
+      end)
+    
+    This had as a consequence to log %TR field with approximatively the same value as
+    the LUA sleep time.
+    
+    Thank you to Patrick Hemmer for having reported this issue.
+    
+    Must be backported to 1.8, 1.7 and 1.6.

+
+    BUG/MEDIUM: mux_pt: dereference the connection with care in mux_pt_wake()
+    
+    mux_pt_wake() calls data->wake() which can return -1 indicating that the
+    connection was just destroyed. We need to check for this condition and
+    immediately exit in this case otherwise we dereference a just freed
+    connection. Note that this mainly happens on idle connections between
+    two HTTP requests. It can have random implications between requests as
+    it may lead a wrong connection's polling to be re-enabled or disabled
+    for example, especially with threads.
+    
+    This patch must be backported to 1.8.
