HAVE_SSL_CTX_SET_CIPHERSUITES is newly defined macro set in openssl-compat.h,
which helps to identify ssl libs (currently OpenSSL-1.1.1 only) that supports
TLS13 cipersuites manipulation on TLS13 context
in the context of a progressive backend migration, we want to be able to
activate SSL on outgoing connections to the server at runtime without
reloading.
This patch adds a `set server ssl` command; in order to allow that:
- add `srv_use_ssl` to `show servers state` command for compatibility,
also update associated parsing
- when using default-server ssl setting, and `no-ssl` on server line,
init SSL ctx without activating it
- when triggering ssl API, de/activate SSL connections as requested
- clean ongoing connections as it is done for addr/port changes, without
checking prior server state
example config:
backend be_foo
default-server ssl
server srv0 127.0.0.1:6011 weight 1 no-ssl
show servers state:
5 be_foo 1 srv0 127.0.0.1 2 0 1 1 15 1 0 4 0 0 0 0 - 6011 - -1
where srv0 can switch to ssl later during the runtime:
set server be_foo/srv0 ssl on
5 be_foo 1 srv0 127.0.0.1 2 0 1 1 15 1 0 4 0 0 0 0 - 6011 - 1
Also update existing tests and create a new one.

a common init for ssl_ctx will be later usable in other functions in
order to support hot enable of ssl during runtime.

Let us use SSL_CTX_set1_curves_list, defined by OpenSSL, as well as in
openssl-compat when SSL_CTRL_SET_CURVES_LIST is present (BoringSSL),
for feature detection instead of versions.
In issue #785, users are reporting that it's not convenient to load a
".crt.key" when the configuration contains a ".crt".
This option allows to remove the extension of the certificate before
trying to load any extra SSL file (.key, .ocsp, .sctl, .issuer etc.)
The patch changes a little bit the way ssl_sock_load_files_into_ckch()
looks for the file.
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
There's no point splitting the file in two since only cfgparse uses the
types defined there. A few call places were updated and cleaned up. All
of them were in C files which register keywords.
There is nothing left in common/ now so this directory must not be used
anymore.
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.
In the CLI command 'show ssl crt-list', the ssl-min-ver and the
ssl-min-max arguments were always displayed because the dumped versions
were the actual version computed and used by haproxy, instead of the
version found in the configuration.
To fix the problem, this patch separates the variables to have one with
the configured version, and one with the actual version used. The dump
only shows the configured version.
The CI revealed that the boringssl build is still broken because of some
ifdef misplacement.
Bug introduced by dad3105 ("REORG: ssl: move ssl configuration to
cfgparse-ssl.c").
No backport needed.
Fix issue #633.
