It's important for the H2 to H1 gateway that the response parser properly
clears the H1 message's body_len when seeing these status codes so that we
don't hang waiting to transfer data that will not come.
A bind_conf does contain a ssl_bind_conf, which already has a flag to know
if early data are activated, so use that, instead of adding a new flag in
the ssl_options field.
Add a new sample fetch, "ssl_fc_has_early", a boolean that will be true
if early data were sent, and a new action, "wait-for-handshake", if used,
the request won't be forwarded until the SSL handshake is done.
It's becoming extremely tricky not to make gcc warn about unused labels
with support for openssl 1.1 and 1.1.1, because some error paths only exist
for certain versions. Latest patch causes a warning for me on 1.0.2. There
is no real point it warning about an unused error label so let's disable
this warning.
When compiled with Openssl >= 1.1.1, before attempting to do the handshake,
try to read any early data. If any early data is present, then we'll create
the session, read the data, and handle the request before we're doing the
handshake.
For this, we add a new connection flag, CO_FL_EARLY_SSL_HS, which is not
part of the CO_FL_HANDSHAKE set, allowing to proceed with a session even
before an SSL handshake is completed.
As early data do have security implication, we let the origin server know
the request comes from early data by adding the "Early-Data" header, as
specified in this draft from the HTTP working group :
https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-replay
Use Openssl-1.1.1 SSL_CTX_set_client_hello_cb to mimic BoringSSL early callback.
Native multi certificate and SSL/TLS method per certificate is now supported by
Openssl >= 1.1.1.
switchctx early callback is only supported for BoringSSL. To prepare
the support of openssl 1.1.1 early callback, convert CBS api to neutral
code to work with any ssl libs.
This patch simply brings HAProxy internal regex system to the Lua API.
Lua doesn't embed regexes, now it inherits from the regexes compiled
with haproxy.
Allow to register a function which will be called after the
configuration file parsing, at the end of the check_config_validity().
It's useful fo checking dependencies between sections or for resolving
keywords, pointers or values.
This commit implements a post section callback. This callback will be
used at the end of a section parsing.
Every call to cfg_register_section must be modified to use the new
prototype:
int cfg_register_section(char *section_name,
int (*section_parser)(const char *, int, char **, int),
int (*post_section_parser)());
Calls to build_logline() are audited in order to use dynamic trash buffers
allocated by alloc_trash_chunk() instead of global trash buffers.
This is similar to commits 07a0fec ("BUG/MEDIUM: http: Prevent
replace-header from overwriting a buffer") and 0d94576 ("BUG/MEDIUM: http:
prevent redirect from overwriting a buffer").
This patch should be backported in 1.7, 1.6 and 1.5. It relies on commit
b686afd ("MINOR: chunks: implement a simple dynamic allocator for trash
buffers") for the trash allocator, which has to be backported as well.
We used to have bo_{get,put}_{chr,blk,str} to retrieve/send data to
the output area of a buffer, but not the equivalent ones for the input
area. This will be needed to copy uploaded data frames in HTTP/2.
When switching the check code to a non-permanent connection, the new code
forgot to free the connection if an error happened and was returned by
connect_conn_chk(), leading to the check never be ran again.
Now when ssl_sock_{to,from}_buf are called, if the connection doesn't
feature CO_FL_WILL_UPDATE, they will first retrieve the updated flags
using conn_refresh_polling_flags() before changing any flag, then call
conn_cond_update_sock_polling() before leaving, to commit such changes.
Now when raw_sock_{to,from}_{pipe,buf} are called, if the connection
doesn't feature CO_FL_WILL_UPDATE, they will first retrieve the updated
flags using conn_refresh_polling_flags() before changing any flag, then
call conn_cond_update_sock_polling() before leaving, to commit such
changes. Note that the only real call to one of the __conn_* functions
is in fact in conn_sock_read0() which is called from here.
This one may be called by upper layers (eg: si_shutw()) or lower layers
(si_shutw() as well during stream_int_notify()) so we want it to take
care of updating the connection's flags if it's not going to be done
by the caller.
In transport-layer functions (snd_buf/rcv_buf), it's very problematic
never to know if polling changes made to the connection will be propagated
or not. This has led to some conn_cond_update_polling() calls being placed
at a few places to cover both the cases where the function is called from
the upper layer and when it's called from the lower layer. With the arrival
of the MUX, this becomes even more complicated, as the upper layer will not
have to manipulate anything from the connection layer directly and will not
have to push such updates directly either. But the snd_buf functions will
need to see their updates committed when called from upper layers.
The solution here is to introduce a connection flag set by the connection
handler (and possibly any other similar place) indicating that the caller
is committed to applying such changes on return. This way, the called
functions will be able to apply such changes by themselves before leaving
when the flag is not set, and the upper layer will not have to care about
that anymore.
This flag is only used when reading using splicing for now, and is only
set when a pipe full condition is met, so we can simplify its reset
condition in conn_refresh_polling_flags so that it's cleared at the
same time as the other ones, only when the control layer is ready.
This flag could be used more, to mark that a buffer full condition was
met with any receive method in order to simplify polling management.
This should probably be revisited after 1.8.
SSL records are 16kB max. When trying to send larger data chunks at once,
SSL_read() only processes 16kB and ssl_sock_from_buf() believes it means
the system buffers are full, which is not the case, contrary to raw_sock.
This is particularly noticeable with HTTP/2 when using a 64kB buffer with
multiple streams, as the mux buffer can start to fill up pretty quickly
in this situation, slowing down the data delivery.
We've been keep this test for a connection being established since 1.5-dev14
when the stream-interface was still accessing the FD directly. The test on
CO_FL_HANDSHAKE and L{4,6}_CONN is totally useless here, and can even be
counter-productive on pure TCP where it could prevent a request from being
sent on a connection still attempting to complete its establishment. And it
creates an abnormal dependency between the layers that will complicate the
implementation of the mux, so let's get rid of it now.
This is based on the git SHA1 implementation and optimized to do word
accesses rather than byte accesses, and to avoid unnecessary copies into
the context array.
in 32af203b75 ("REORG: cli: move ssl CLI functions to ssl_sock.c")
"set ssl tls-key" was accidentally replaced with "set ssl tls-keys"
(keys instead of key). This is undocumented and breaks upgrades from
1.6 to 1.7.
This patch restores "set ssl tls-key" and also registers a helptext.
This should be backported to 1.7.
Commit 872085ce "BUG/MINOR: ssl: ocsp response with 'revoked' status is correct"
introduce a regression. OCSP_single_get0_status can return -1 and haproxy must
generate an error in this case.
Thanks to Sander Hoentjen who have spotted the regression.
This patch should be backported in 1.7, 1.6 and 1.5 if the patch above is
backported.
BoringSSL switch OPENSSL_VERSION_NUMBER to 1.1.0 for compatibility.
Fix BoringSSL call and openssl-compat.h/#define occordingly.
This will not break openssl/libressl compat.
On x86_64, when gcc instruments functions and compiles at -O0, it saves
the function's return value in register rbx before calling the trace
callback. It provides a nice opportunity to display certain useful
values (flags, booleans etc) during trace sessions. It's absolutely
not guaranteed that it will always work but it provides a considerable
help when it does so it's worth activating it. When building on a
different architecture, the value 0 is always reported as the return
value. On x86_64 with optimizations (-O), the RBX register will not
necessarily match and random values will be reported, but since it's
not the primary target it's not a problem.
Now any call to trace() in the code will automatically appear interleaved
with the call sequence and timestamped in the trace file. They appear with
a '#' on the 3rd argument (caller's pointer) in order to make them easy to
spot. If the trace functionality is not used, a dmumy weak function is used
instead so that it doesn't require to recompile every time traces are
enabled/disabled.
The trace decoder knows how to deal with these messages, detects them and
indents them similarly to the currently traced function. This can be used
to print function arguments for example.
Note that we systematically flush the log when calling trace() to ensure we
never miss important events, so this may impact performance.
The trace() function uses the same format as printf() so it should be easy
to setup during debugging sessions.
Don't forget to allocate tmptrash before using it, and free it once we're
done.

- BUG/MINOR: ssl: ocsp response with 'revoked' status is correct
ocsp_status can be 'good', 'revoked', or 'unknown'. 'revoked' status
is a correct status and should not be dropped.
In case of certificate with OCSP must-stapling extension, response with
'revoked' status must be provided as well as 'good' status.
This patch can be backported in 1.7, 1.6 and 1.5.
Now only conn_full_close() will be used. It will become more obvious
when the tracking is in place or not and will make it easier to
convert remaining call places to conn_streams.
