3139c1b198 BUG/MINOR: ssl: Possible memleak when allowing the 0RTT data buffer.
​
As the server early data buffer is allocated in the middle of the loop
used to allocate the SSL session without being freed before retrying,
this leads to a memory leak.
​
To fix this we move the section of code responsible of this early data buffer
alloction after the one reponsible of allocating the SSL session.
​
Must be backported to 2.1 and 2.0.

fa10ffdd12 REGTESTS: make the set_ssl_cert test require version 2.2
It doesn't only use "set ssl cert" but also relies on "show ssl cert"
which is only available in 2.2.

ecffb7d841 BUG/MEDIUM: streams: Move the conn_stream allocation outside #IF USE_OPENSSL.
When commit 477902bd2e made the conn_stream
allocation unconditional, it unfortunately moved the code doing the allocation
inside #if USE_OPENSSL, which means anybody compiling haproxy without
openssl wouldn't allocate any conn_stream, and would get a segfault later.
Fix that by moving the code that does the allocation outside #if USE_OPENSSL.

99ac8a1aa4 BUG/MINOR: stream: Be sure to have a listener to increment its counters
In process_stream(), when a client or a server abort is handled, the
corresponding listener's counter is incremented. But, we must be sure to have a
listener attached to the session. This bug was introduced by the commit
cff0f739e5.

Thanks to Fred to reporting me the bug.

No need to backport this patch, except if commit cff0f739e5 is backported.

be20cf36af BUG/MINOR: http-ana: Increment the backend counters on the backend
A stupid cut-paste bug was introduced in the commit cff0f739e5. Backend
counters must of course be incremented on the stream's backend. Not the
frontend.

645c588e71 BUILD: cfgparse: silence a bogus gcc warning on 32-bit machines
A first patch was made during 2.0-dev to silence a bogus warning emitted
by gcc : dd1c8f1f72 ("MINOR: cfgparse: Add a cast to make gcc happier."),
but it happens it was not sufficient as the warning re-appeared on 32-bit
machines under gcc-8 and gcc-9 :

  src/cfgparse.c: In function 'check_config_validity':
  src/cfgparse.c:3642:33: warning: argument 1 range [2147483648, 4294967295] exceeds maximum object size 2147483647 [-Walloc-size-larger-than=]
       newsrv->idle_orphan_conns = calloc((unsigned int)global.nbthread, sizeof(*newsrv->idle_orphan_conns));
                                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This warning doesn't trigger in other locations, and it immediately
vanishes if the previous or subsequent loops do not depend on
global.nbthread anymore, or if the field ordering of the struct server
changes! As discussed in the thread at:

   https://www.mail-archive.com/haproxy@formilux.org/msg36107.html

playing with -Walloc-size-larger-than has no effect. And a minimal
reproducer could be isolated, indicating it's pointless to circle around
this one. Let's just cast nbthread to ushort so that gcc cannot make
this wrong detection. It's unlikely we'll use more than 65535 threads in
the near future anyway.

This may be backported to older releases if they are also affected, at
least to ease the job of distro maintainers.

Thanks to Ilya for testing.

bb2c4ae065 BUG/MEDIUM: mux-h2: make sure we don't emit TE headers with anything but "trailers"
While the H2 parser properly checks for the absence of anything but
"trailers" in the TE header field, we forget to check this when sending
the request to an H2 server. The problem is that an H2->H2 conversion
may keep "gzip" and fail on the next stage.

This patch makes sure that we only send "TE: trailers" if the TE header
contains the "trailers" token, otherwise it's dropped.

This fixes issue #464 and should be backported till 1.9.

Since commit 1b8e68e89a ("MEDIUM: stick-table: Stop handling stick-tables

to the following error :

  [ALERT] 023/071924 (16479) : Proxy 'px': unable to find stick-table '(null)'.
  [ALERT] 023/071914 (16479) : Fatal errors found in configuration.

f22758d12a MINOR: connection: remove some unneeded checks for CO_FL_SOCK_WR_SH
A few places in health checks and stream-int on the send path were still
checking for this flag. Now we do not and instead we rely on snd_buf()
to report the error if any.

It's worth noting that all 3 real muxes still use CO_FL_SOCK_WR_SH and
CO_FL_ERROR interchangeably at various places to decide to abort and/or
free their data. This should be clarified and fixed so that only
CO_FL_ERROR is used, and this will render the error paths simpler and
more accurate.

a8c7e8e3a8 MINOR: raw-sock: always check for CO_FL_SOCK_WR_SH before sending
The test was added before splice() and send() to make sure we never
accidently send after a shutdown, because upper layers do not all
check and it's not their job to do it. In such a case we also set
errno to EPIPE so that the error can be accurately reported, e.g.,
in health checks.

49139cb914 MINOR: connection: don't check for CO_FL_SOCK_WR_SH too early in handshakes
Just like with CO_FL_SOCK_RD_SH, we don't need to check for this flag too
early because conn_sock_send() already does it. No error was lost so it
was harmless, it was only useless code.

d838fb840c MINOR: connection: do not check for CO_FL_SOCK_RD_SH too early
The handshake functions dedicated to proxy proto, netscaler and
socks4 all check for this flag before proceeding. This is wrong,
they must not do and instead perform the call to recv() then
report the close. The reason for this is that the current
construct managed to lose the CO_ER_CIP_EMPTY error code in case
the connection was already shut, thus causing a race condition
with some errors being reported correctly or as unknown depending
on the timing.

6d015724ec MINOR: connection: remove checks for CO_FL_HANDSHAKE before I/O
There are still leftovers from the pre-xprt_handshake era with lots
of places where I/O callbacks refrain from receiving/sending if they
see that a handshake is present. This needlessly duplicates the
subscribe calls as it will automatically be done by the underlying
xprt_handshake code when attempting the operation.

The only reason for still checking CO_FL_HANDSHAKE is when we decide
to instantiate xprt_handshake. This patch removes all other ones.

911db9bd29 MEDIUM: connection: use CO_FL_WAIT_XPRT more consistently than L4/L6/HANDSHAKE
As mentioned in commit c192b0ab95 ("MEDIUM: connection: remove
CO_FL_CONNECTED and only rely on CO_FL_WAIT_*"), there is a lack of
consistency on which flags are checked among L4/L6/HANDSHAKE depending
on the code areas. A number of sample fetch functions only check for
L4L6 to report MAY_CHANGE, some places only check for HANDSHAKE and
many check both L4L6 and HANDSHAKE.

This patch starts to make all of this more consistent by introducing a
new mask CO_FL_WAIT_XPRT which is the union of L4/L6/HANDSHAKE and
reports whether the transport layer is ready or not.

All inconsistent call places were updated to rely on this one each time
the goal was to check for the readiness of the transport layer.

4450b587dd MINOR: connection: remove CO_FL_SSL_WAIT_HS from CO_FL_HANDSHAKE
Most places continue to check CO_FL_HANDSHAKE while in fact they should
check CO_FL_HANDSHAKE_NOSSL, which contains all handshakes but the one
dedicated to SSL renegotiation. In fact the SSL layer should be the
only one checking CO_FL_SSL_WAIT_HS, so as to avoid processing data
when a renegotiation is in progress, but other ones randomly include it
without knowing. And ideally it should even be an internal flag that's
not exposed in the connection.

This patch takes CO_FL_SSL_WAIT_HS out of CO_FL_HANDSHAKE, uses this flag
consistently all over the code, and gets rid of CO_FL_HANDSHAKE_NOSSL.

In order to limit the confusion that has accumulated over time, the
CO_FL_SSL_WAIT_HS flag which indicates an ongoing SSL handshake,
possibly used by a renegotiation was moved after the other ones.

As mentioned in c192b0ab95 ("MEDIUM: connection: remove CO_FL_CONNECTED
and only rely on CO_FL_WAIT_*"), si_cs_recv() currently does not propagate
CS_FL_EOS to CF_READ_NULL if CO_FL_WAIT_L4L6 is set, while this situation
doesn't exist anymore. Let's get rid of this confusing test.

220a26c316 BUG/MEDIUM: 0rtt: Only consider the SSL handshake.
We only add the Early-data header, or get ssl_fc_has_early to return 1, if
we didn't already did the SSL handshake, as otherwise, we know the early
data were fine, and there's no risk of replay attack. But to do so, we
wrongly checked CO_FL_HANDSHAKE, we have to check CO_FL_SSL_WAIT_HS instead,
as we don't care about the status of any other handshake.

This should be backported to 2.1, 2.0, and 1.9.

should return

c192b0ab95 MEDIUM: connection: remove CO_FL_CONNECTED and only rely on CO_FL_WAIT_*
Commit 477902bd2e ("MEDIUM: connections: Get ride of the xprt_done
callback.") broke the master CLI for a very obscure reason. It happens
that short requests immediately terminated by a shutdown are properly
received, CS_FL_EOS is correctly set, but in si_cs_recv(), we refrain
from setting CF_SHUTR on the channel because CO_FL_CONNECTED was not
yet set on the connection since we've not passed again through
conn_fd_handler() and it was not done in conn_complete_session(). While
commit a8a415d31a ("BUG/MEDIUM: connections: Set CO_FL_CONNECTED in
conn_complete_session()") fixed the issue, such accident may happen
again as the root cause is deeper and actually comes down to the fact
that CO_FL_CONNECTED is lazily set at various check points in the code
but not every time we drop one wait bit. It is not the first time we
face this situation.

Originally this flag was used to detect the transition between WAIT_*
and CONNECTED in order to call ->wake() from the FD handler. But since
at least 1.8-dev1 with commit 7bf3fa3c23 ("BUG/MAJOR: connection: update
CO_FL_CONNECTED before calling the data layer"), CO_FL_CONNECTED is
always synchronized against the two others before being checked. Moreover,
with the I/Os moved to tasklets, the decision to call the ->wake() function
is performed after the I/Os in si_cs_process() and equivalent, which don't
care about this transition either.

So in essence, checking for CO_FL_CONNECTED has become a lazy wait to
check for (CO_FL_WAIT_L4_CONN | CO_FL_WAIT_L6_CONN), but that always
relies on someone else having synchronized it.

This patch addresses it once for all by killing this flag and only checking
the two others (for which a composite mask CO_FL_WAIT_L4L6 was added). This
revealed a number of inconsistencies that were purposely not addressed here
for the sake of bisectability:

  - while most places do check both L4+L6 and HANDSHAKE at the same time,
    some places like assign_server() or back_handle_st_con() and a few
    sample fetches looking for proxy protocol do check for L4+L6 but
    don't care about HANDSHAKE ; these ones will probably fail on TCP
    request session rules if the handshake is not complete.

  - some handshake handlers do validate that a connection is established
    at L4 but didn't clear CO_FL_WAIT_L4_CONN

  - the ->ctl method of mux_fcgi, mux_pt and mux_h1 only checks for L4+L6
    before declaring the mux ready while the snd_buf function also checks
    for the handshake's completion. Likely the former should validate the
    handshake as well and we should get rid of these extra tests in snd_buf.

  - raw_sock_from_buf() would directly set CO_FL_CONNECTED and would only
    later clear CO_FL_WAIT_L4_CONN.

  - xprt_handshake would set CO_FL_CONNECTED itself without actually
    clearing CO_FL_WAIT_L4_CONN, which could apparently happen only if
    waiting for a pure Rx handshake.

  - most places in ssl_sock that were checking CO_FL_CONNECTED don't need
    to include the L4 check as an L6 check is enough to decide whether to
    wait for more info or not.

It also becomes obvious when reading the test in si_cs_recv() that caused
the failure mentioned above that once converted it doesn't make any sense
anymore: having CS_FL_EOS set while still waiting for L4 and L6 to complete
cannot happen since for CS_FL_EOS to be set, the other ones must have been
validated.

Some of these parts will still deserve further cleanup, and some of the
observations above may induce some backports of potential bug fixes once
totally analyzed in their context. The risk of breaking existing stuff
is too high to blindly backport everything.

d0142e7224 MINOR: cli: Report location of errors or any extra data for "show table"
When using multiple filters with "show table", it can be useful to
report which filter entry failed

  > show table MY_TABLE data.gpc0 gt 0 data.gpc0a lt 1000
  Filter entry #2: Unknown data type

  > show table MY_TABLE data.gpc0 gt 0 data.gpc0 lt 1000a
  Filter entry #2: Require a valid integer value to compare against

We now also catch garbage data after the filter

  > show table MY_TABLE data.gpc0 gt 0 data.gpc0 lt 1000 data.gpc0 gt 1\
    data.gpc0 gt 10 a
  Detected extra data in filter, 16th word of input, after '10'

Even before multi-filter feature we've also silently accepted garbage
after the input, hiding potential bugs

  > show table MY_TABLE data.gpc0 gt 0 data.gpc0
or
  > show table MY_TABLE data.gpc0 gt 0 a

In both cases, only first filter entry would be used, silently ignoring
extra filter entry or garbage data.

Last, but not the least, it is now possible to detect multi-filter
feature from cli with something like the following:

  > show table MY_TABLE data.blah
  Filter entry #1: Unknown data type

477902bd2e MEDIUM: connections: Get ride of the xprt_done callback.
The xprt_done_cb callback was used to defer some connection initialization
until we're connected and the handshake are done. As it mostly consists of
creating the mux, instead of using the callback, introduce a conn_create_mux()
function, that will just call conn_complete_session() for frontend, and
create the mux for backend.

056c629531 BUG/MINOR: ssl: fix build on development versions of openssl-1.1.x
while working on issue #429, I encountered build failures with various
non-released openssl versions, let us improve ssl defines, switch to
features, not versions, for EVP_CTRL_AEAD_SET_IVLEN and
EVP_CTRL_AEAD_SET_TAG.

No backport is needed as there is no valid reason to build a stable haproxy
version against a development version of openssl.

19a69b3740 BUG/MINOR: http_act: don't check capture id in backend
A wrong behavior was introduced by
e9544935e8, leading to preventing loading
any configuration where a capture slot id is used in a backend.
IE, the configuration below does not parse:

  frontend f
   bind *:80
   declare capture request len 32
   default_backend webserver

  backend webserver
   http-request capture req.hdr(Host) id 1

The point is that such type of configuration is valid and should run.

This patch enforces the check of capture slot id only if the action rule
is configured in a frontend.
The point is that at configuration parsing time, it is impossible to
check which frontend could point to this backend (furthermore if we use
dynamic backend name resolution at runtime).

The documentation has been updated to warn the user to ensure that
relevant frontends have required declaration when such rule has to be
used in a backend.
If no capture slot can be found, then the action will just not be
executed and HAProxy will process the next one in the list, as expected.

This should be backported to all supported branches (bug created as part
of a bug fix introduced into 1.7 and backported to 1.6).

6a0dd73390 CLEANUP: Consistently unsigned int for bitfields
Signed bitfields of size `1` hold the values `0` and `-1`, but are
usually assigned `1`, possibly leading to subtle bugs when the value
is explicitely compared against `1`.

13a9232ebc MEDIUM: dns: use Additional records from SRV responses
Most DNS servers provide A/AAAA records in the Additional section of a
response, which correspond to the SRV records from the Answer section:

  ;; QUESTION SECTION:
  ;_http._tcp.be1.domain.tld.     IN      SRV

  ;; ANSWER SECTION:

  ;; ADDITIONAL SECTION:

  A8.domain.tld.          3600    IN      A       192.168.0.8

SRV record support was introduced in HAProxy 1.8 and the first design
did not take into account the records from the Additional section.
Instead, a new resolution is associated to each server with its relevant
FQDN.
This behavior generates a lot of DNS requests (1 SRV + 1 per server
associated).

This patch aims at fixing this by:
- when a DNS response is validated, we associate A/AAAA records to
  relevant SRV ones
- set a flag on associated servers to prevent them from running a DNS
  resolution for said FADN
- update server IP address with information found in the Additional
  section

If no relevant record can be found in the Additional section, then
HAProxy will failback to running a dedicated resolution for this server,
as it used to do.
This behavior is the one described in RFC 2782.

2f5339079b MINOR: proxy/http-ana: Add support of extra attributes for the cookie directive
It is now possible to insert any attribute when a cookie is inserted by
HAProxy. Any value may be set, no check is performed except the syntax validity
(CTRL chars and ';' are forbidden). For instance, it may be used to add the
SameSite attribute:

    cookie SRV insert attr "SameSite=Strict"

The attr option may be repeated to add several attributes.

This patch should fix the issue #361.
