-    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
-     address deduplication used on 1.8 apparently is not suited to everyone]

-+  * 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)

-         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.

-    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 server-specific CLI commands "set weight", "set maxconn",
-    "disable agent", "enable agent", "disable health", "enable health",
-    "disable server" and "enable server" were not protected against
-    concurrent accesses. Now they take the server lock around the
-    sensitive part.
-    
-    This patch must be backported to 1.8.

-    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.
