2a77c62c18 REGTESTS: ssl: Add "show ssl ocsp-response" test
This file adds tests for the new "show ssl ocsp-response" command and
the new "show ssl cert foo.pem.ocsp" and "show ssl cert *foo.pem.ocsp"
special cases. They are all used to display information about an OCSP
response, committed or not.

6056e61ae2 MINOR: ssl: Add the "show ssl cert foo.pem.ocsp" CLI command
Add the ability to dump an OCSP response details through a call to "show
ssl cert cert.pem.ocsp". It can also be used on an ongoing transaction
by prefixing the certificate name with a '*'.
Even if the ckch structure holds an ocsp_response buffer, we still need
to look for the actual ocsp response entry in the ocsp response tree
rather than just dumping the ckch's buffer details because when updating
an ocsp response through a "set ssl ocsp-response" call, the
corresponding buffer in the ckch is not updated accordingly. So this
buffer, even if it is not empty, might hold an outdated ocsp response.

da968f69c7 MINOR: ssl: Add the OCSP entry key when displaying the details of a certificate
This patch adds an "OCSP Response Key" information in the output of a
"show ssl cert <certfile>" call. The key can then be used in a "show ssl
ocsp-response <key>" CLI command.

d92fd11c77 MINOR: ssl: Add new "show ssl ocsp-response" CLI command
This patch adds the "show ssl ocsp-response [<id>]" CLI command. This
command can be used to display the IDs of the OCSP tree entries along
with details about the entries' certificate ID (issuer's name and key
hash + serial number), or to display the details of a single
ocsp-response if an ID is given. The details displayed in this latter
case are the ones shown by a "openssl ocsp -respin <ocsp-response>
-text" call.

5aa1dce5ee MINOR: ssl: Keep the actual key length in the certificate_ocsp structure
The OCSP tree entry key is a serialized version of the OCSP_CERTID of
the entry which is stored in a buffer that can be at most 128 bytes.
Depending on the length of the serial number, the actual non-zero part
of the key can be smaller than 128 bytes and this new structure member
allows to know how many of the bytes are filled. It will be useful when
dumping the key (in a "show ssl cert <cert>" output for instance).

12554d00f6 BUG/MEDIUM: compression: Add a flag to know the filter is still processing data
Since the commit acfd71b97 ("BUG/MINOR: http-comp: Preserve
HTTP_MSGF_COMPRESSIONG flag on the response"), there is no more flag to know
when the compression ends. This means it is possible to finish the
compression several time if there are trailers.

So, we reintroduce almost the same mechanism but with a dedicated flag. So
now, there is a bits field in the compression filter context.

The commit above is marked to be backported as far as 2.0. Thus this patch
must also be backported as far as 2.0.

402740c3ad BUG/MEDIUM: compression: Properly get the next block to iterate on payload
When a DATA block is compressed, or when the compression context is finished
on a TLR/EOT block, the next block used to loop on the HTX message must be
refreshed because a defragmentation may have occurred.

This bug was introduced when the EOM block was removed in 2.4. Thus, this
patch must be backported to 2.4.

86ca0e52f7 BUG/MEDIUM: compression: Fix loop skipping unused blocks to get the next block
In comp_http_payload(), the loop skipping unused blocks is buggy and may
lead to a infinite loop if the first next block is unused. Indeed instead of
iterating on blocks, we always retrieve the same one because <blk> is used
instead of <next> to get the next block.

This bug was introduced when the EOM block was removed in 2.4. Thus, this
patch must be backported to 2.4.

9425ed488f BUG/MEDIUM: opentracing: initialization before establishing daemon and/or chroot mode
This patch solves the problem reported in github issue #1204, where the
OpenTracing filter cannot communicate with the selected tracer if HAProxy
is run in daemon mode.

This commit also solves github issue #1274, where the problem manifests
itself when using the 'chroot' keyword in the HAProxy configuration.

This is solved so that the initialization of the OpenTracing plugin is
split into two operations, first the plugin (dynamic library) is loaded
before switching the HAProxy to daemon mode (or chroot) and then the
tracer thread is started.

This means that nothing is retrieved from the file system in runtime.

After applying this commit, opentracing C wrapper version 1.1.0 should be
used because the earlier version does not have separated initialization
functions.

This resolves GitHub issues #1204 and #1274.

1642474054 Revert "BUG/MINOR: opentracing: initialization after establishing daemon mode"
This reverts commit f2263435d7.

This commit is unnecessary because although it solves the problem of using
the OpenTracing filter in daemon mode, it does not solve the same problem
if chroot is used.

The following commit related to the OpenTracing filter solves both problems
efficiently.

a3a0cce8ee BUG/MINOR: ssl: OCSP stapling does not work if expire too far in the future
The wey the "Next Update" field of the OCSP response is converted into a
timestamp relies on the use of signed integers for the year and month so
if the calculated timestamp happens to overflow INT_MAX, it ends up
being seen as negative and the OCSP response being dwignored in
ssl_sock_ocsp_stapling_cbk (because of the "ocsp->expire < now.tv_sec"
test).

It could be backported to all stable branches.

722180aca8 BUILD: make tune.ssl.keylog available again
Since commit 04a5a44 ("BUILD: ssl: use HAVE_OPENSSL_KEYLOG instead of
OpenSSL versions") the "tune.ssl.keylog" feature is broken because
HAVE_OPENSSL_KEYLOG does not exist.

Replace this by a HAVE_SSL_KEYLOG which is defined in openssl-compat.h.
Also add an error when not built with the right openssl version.

846830e47d BUG: errors: remove printf positional args for user messages context
Change the algorithm for the generation of the user messages context
prefix. Remove the dubious API relying on optional printf positional
arguments. This may be non portable, and in fact the CI glibc crashes
with the following error when some arguments are not present in the
format string :

"invalid %N$ use detected".

Now, a fixed buffer attached to the context instance is allocated once
for the program lifetime. Then call repeatedly snprintf with the
optional arguments of context if present to build the context string.
The buffer is deallocated via a per-thread free handler.

This does not need to be backported.

fc0cceb08a MINOR: haproxy: Add -cc argument
This patch adds the `-cc` (check condition) argument to evaluate conditions on
startup and return the result as the exit code.

As an example this can be used to easily check HAProxy's version in scripts:

    haproxy -cc 'version_atleast(2.4)'

This resolves GitHub issue #1246.

3b9cb60059 REGTESTS: Fix http_abortonclose.vtc to support -1 status for some client aborts
Since the commit 5e702fcad ("MINOR: http-ana: Use -1 status for client
aborts during queuing and connect"), -1 status is reported in the log
message when the client aborts during queuing and
connect. http_abortonclose.vtc script must be update accordingly.

5e702fcadc MINOR: http-ana: Use -1 status for client aborts during queuing and connect
When a client aborts while the session is in the queue or during the connect
stage, instead of reporting a 503-Service-Unavailable error in logs, -1
status is used. It means -1 status is now reported with 'CC' and 'CQ'
termination state.

Indeed, when a client aborts before the server connection is established,
there is no reason to report a 503 because nothing is sent to the
server. And in this case, because it is a client abort, it is useless to
send any response to the client. Thus -1 status is approriate. This status
is used in log messages when the connection is closed and no response is
sent.

This patch should fix the issue #1266.

It is now possible to get any variables from the cli. Concretely, only

nor session defined. But, nothing forbids anyone to try to get a variable in

session must be tested before retrieving variables in CHECK scope.

f822decfda BUG/MAJOR: stream-int: Release SI endpoint on server side ASAP on retry
When a connection attempt failed, if a retry is possible, the SI endpoint on
the server side is immediately released, instead of waiting to establish a
new connection to a server. Thus, when the backend SI is switched from
SI_ST_CER state to SI_ST_REQ, SI_ST_ASS or SI_ST_TAR, its endpoint is
released. It is expected because the SI is moved to a state prior to the
connection stage ( < SI_ST_CONN). So it seems logical to not have any server
connection.

It is especially important if the retry is delayed (SI_ST_TAR or
SI_ST_QUE). Because, if the server connection is preserved, any error at the
connection level is unexpectedly relayed to the stream, via the
stream-interface, leading to an infinite loop in process_stream(). if
SI_FL_ERR flag is set on the backend SI in another state than SI_ST_CLO, an
internal goto is performed to resync the stream-interfaces. In addtition,
some ressources are not released ASAP.

This bug is quite old and was reported 1 or 2 times per years since the 2.2
(at least) with not enough information to catch it. It must be backported as
far as 2.2 with a special care because this part has moved several times and
after some observation period and feedback from users to be sure. For info,
in 2.0 and prior, the connection is released when an error is encountered in
SI_ST_CON or SI_ST_RDY states.
