let us use SSL_CTRL_GET_RAW_CIPHERLIST for feature detection instead
of versions
[wla: SSL_CTRL_GET_RAW_CIPHERLIST was introduced by OpenSSL commit
94a209 along with SSL_CIPHER_find. It was removed in boringSSL.]

smp_fetch_ssl_x_chain_der() uses the SSL_get_peer_cert_chain() which
does not increment the refcount of the chain, so it should not be free'd.
The bug was introduced by a598b50 ("MINOR: ssl: add ssl_{c,s}_chain_der
fetch methods"). No backport needed.
Following work from Arjen and Mathilde, it adds ssl_{c,s}_chain_der
methods; it returns DER encoded certs from SSL_get_peer_cert_chain
Also update existing vtc tests to add random intermediate certificates
When getting the result through this header:
http-response add-header x-ssl-chain-der %[ssl_c_chain_der,hex]
One can parse it with any lib accepting ASN.1 DER data, such as in go:
bin, err := encoding/hex.DecodeString(cert)
certs_parsed, err := x509.ParseCertificates(bin)

Add a check on the conn pointer to avoid a NULL dereference in
smp_fetch_ssl_x_keylog().
The problem is not suppose to happen because the function is only used
for the frontend at the moment.
Introduced by 7d42ef5, 2.2 only.
Fix issue #733.
OpenSSL 1.1.1 provides a callback registering function
SSL_CTX_set_keylog_callback, which allows one to receive a string
containing the keys to deciphers TLSv1.3.
Unfortunately it is not possible to store this data in binary form and
we can only get this information using the callback. Which means that we
need to store it until the connection is closed.
This patches add 2 pools, the first one, pool_head_ssl_keylog is used to
store a struct ssl_keylog which will be inserted as a ex_data in a SSL *.
The second one is pool_head_ssl_keylog_str which will be used to store
the hexadecimal strings.
To enable the capture of the keys, you need to set "tune.ssl.keylog on"
in your configuration.
The following fetches were implemented:
ssl_fc_client_early_traffic_secret,
ssl_fc_client_handshake_traffic_secret,
ssl_fc_server_handshake_traffic_secret,
ssl_fc_client_traffic_secret_0,
ssl_fc_server_traffic_secret_0,
ssl_fc_exporter_secret,
ssl_fc_early_exporter_secret
This commit adds some sample fetches that were lacking on the server
side:
ssl_s_key_alg, ssl_s_notafter, ssl_s_notbefore, ssl_s_sig_alg,
ssl_s_i_dn, ssl_s_s_dn, ssl_s_serial, ssl_s_sha1, ssl_s_der,
ssl_s_version
This patch fixes all the leftovers from the include cleanup campaign. There
were not that many (~400 entries in ~150 files) but it was definitely worth
doing it as it revealed a few duplicates.
The files were moved almost as-is, just dropping arg-t and auth-t from
acl-t but keeping arg-t in acl.h. It was useful to revisit the call places
since a handful of files used to continue to include acl.h while they did
not need it at all. Struct stream was only made a forward declaration
since not otherwise needed.
This one is particularly tricky to move because everyone uses it
and it depends on a lot of other types. For example it cannot include
arg-t.h and must absolutely only rely on forward declarations to avoid
dependency loops between vars -> sample_data -> arg. In order to address
this one, it would be nice to split the sample_data part out of sample.h.
And also rename standard.c to tools.c. The original split between
tools.h and standard.h dates from version 1.3-dev and was mostly an
accident. This patch moves the files back to what they were expected
to be, and takes care of not changing anything else. However this
time tools.h was split between functions and types, because it contains
a small number of commonly used macros and structures (e.g. name_desc)
which in turn cause the massive list of includes of tools.h to conflict
with the callers.
They remain the ugliest files of the whole project and definitely need
to be cleaned and split apart. A few types are defined there only for
functions provided there, and some parts are even OS-specific and should
move somewhere else, such as the symbol resolution code.
The pretty confusing "buffer.h" was in fact not the place to look for
the definition of "struct buffer" but the one responsible for dynamic
buffer allocation. As such it defines the struct buffer_wait and the
few functions to allocate a buffer or wait for one.
This patch moves it renaming it to dynbuf.h. The type definition was
moved to its own file since it's included in a number of other structs.
Doing this cleanup revealed that a significant number of files used to
rely on this one to inherit struct buffer through it but didn't need
anything from this file at all.
This file is to openssl what compat.h is to the libc, so it makes sense
to move it to haproxy/. It could almost be part of api.h but given the
amount of openssl stuff that gets loaded I fear it could increase the
build time.
Note that this file contains lots of inlined functions. But since it
does not depend on anything else in haproxy, it remains safe to keep
all that together.
All files that were including one of the following include files have
been updated to only include haproxy/api.h or haproxy/api-t.h once instead:
- common/config.h
- common/compat.h
- common/compiler.h
- common/defaults.h
- common/initcall.h
- common/tools.h
The choice is simple: if the file only requires type definitions, it includes
api-t.h, otherwise it includes the full api.h.
In addition, in these files, explicit includes for inttypes.h and limits.h
were dropped since these are now covered by api.h and api-t.h.
No other change was performed, given that this patch is large and
affects 201 files. At least one (tools.h) was already freestanding and
didn't get the new one added.
