Adds a new sample fetch method to get the curve name used in the
key agreement to enable better observability. In OpenSSLv3, the function
`SSL_get_negotiated_group` returns the NID of the curve and from the NID,
we get the curve name by passing the NID to OBJ_nid2sn. This was not
available in v1.1.1. SSL_get_curve_name(), which returns the curve name
directly was merged into OpenSSL master branch last week but will be available
only in its next release.
When a s-maxage cache-control directive is present, it overrides any
other max-age or expires value (see section 5.2.2.9 of RFC7234). So if
we have a max-age=0 alongside a strictly positive s-maxage, the response
should be cached.
This bug was raised in GitHub issue #2203.
The fix can be backported to all stable branches.
In GH #2187 it was mentioned that the ifnone-forwardfor regtest
did not cover the case where forwardfor ifnone is explicitly set in
the frontend but forwardfor option is not used in the backend.
Expected behavior in this case is that the frontend takes the precedence
because the backend did not specify the option.
Adding this missing case to prevent regressions in the future.
Depending on the timing, time to time, the log messages can be mixed. A
client can start and be fully handled by HAProxy (including its log message)
before the log message of the previous client was emitted or received. To
fix the issue, a barrier was added to be sure to eval the "expect" rule on
logs before starting the next client.
Because of the commit 5cb8d7b8f ("BUG/MINOR: peers: Improve detection of
config errors in peers sections"), 2 scripts now report errors during
startup because some variables are not set and the remote peer server is
thus malformed. To perform a peer synchro between 2 haproxys in these
scripts, the startup must be delayed to properly resolve addresses.
In addidiotn, we must wait (2s) to be sure the connection between peers is
properly established. These scripts are now flagged as slow.
As seen in commits 33a4461fa ("BUG/MINOR: stats: Fix Lua's `get_stats`
function") and a46b142e8 ("BUG/MINOR: Missing stat_field_names (since
f21d17bb)") it seems frequent to omit to update stats_fields[] when
adding a new ST_F_xxx entry. This breaks Lua's get_stats() and shows
a "(null)" in the header of "show stat", but that one is not detectable
to the naked eye anymore.
Let's add a reminder above the enum declaration about this, and a small
reg tests checking for the absence of "(null)". It was verified to fail
before the last patch above.
When a message is compressed, A "Vary" header is added with
"accept-encoding" value. However, a new header is always added, regardless
there is already a Vary header or not. In addition, if there is already a
Vary header, there is no check on values to be sure "accept-encoding" value
is not already there. So it is possible to have it twice.
To improve this part, we now test Vary header values and "accept-encoding"
is only added if it was not found. In addition, "accept-encoding" value is
appended to the last Vary header found, if any. Otherwise, a new header is
added.
It was previously reduced from 10s to 1s but it remains too high, espeically
for the CI. It may be drastically reduced to 100ms. Idea is to just be sure
we will wait for the response before evaluating the TCP rules.
Because of the previous fix, log/last_rule.vtc script is failing. The
inspect-delay is no longer shorten when the end of the message is
reached. Thus WAIT_END acl is trully respected. 10s is too high and hit the
Vtext timeout, making the script fails.
Fix the openssl build with older openssl version by disabling the new
ssl_c_r_dn fetch.
This also disable the ssl_client_samples.vtc file for OpenSSL version
older than 1.1.1
This patch addresses #1514, adds the ability to fetch DN of the root
ca that was in the chain when client certificate was verified during SSL
handshake.
Since mailers/healthcheckmail.vtc already requires lua to emulate the
SMTP server for the test, force it to use lua mailers example script
to send email-alerts so we don't rely anymore on legacy tcpcheck
mailers implementation.
This is done by simply loading examples/mailers.lua (as a symlink) from
haproxy config file.
As this feature has a dependency on resolvers being configured,
this test acts as good documentation as well.
This change also has a spelling fix for filename.
This commit makes sure that if three is no "alpn", "npn" nor "no-alpn"
setting on a "bind" line which corresponds to an HTTPS or QUIC frontend,
we automatically turn on "h2,http/1.1" as an ALPN default for an HTTP
listener, and "h3" for a QUIC listener. This simplifies the configuration
for end users since they won't have to explicitly configure the ALPN
string to enable H2, considering that at the time of writing, HTTP/1.1
represents less than 7% of the traffic on large infrastructures. The
doc and regtests were updated. For more info, refer to the following
thread:
https://www.mail-archive.com/haproxy@formilux.org/msg43410.html
Since the commit f2b02cfd9 ("MAJOR: http-ana: Review error handling during
HTTP payload forwarding"), during the payload forwarding, we are analyzing a
side, we stop to test the opposite side. It means when the HTTP request
forwarding analyzer is called, we no longer check the response side and vice
versa.
Unfortunately, since then, the HTTP tunneling is broken after a protocol
upgrade. On the response is switch in TUNNEL mode. The request remains in
DONE state. As a consequence, data received from the server are forwarded to
the client but not data received from the client.
To fix the bug, when both sides are in DONE state, both are switched in same
time in TUNNEL mode if it was requested. It is performed in the same way in
http_end_request() and http_end_response().
This patch should fix the issue #2125. It is 2.8-specific. No backport
needed.
This patch proposes to enumerate servers using internal HAProxy list.
Also, remove the flag SRV_F_NON_PURGEABLE which makes the server non
purgeable each time Lua uses the server.
Removing reg-tests/cli_delete_server_lua.vtc since this test is no
longer relevant (we don't set the SRV_F_NON_PURGEABLE flag anymore)
and we already have a more generic test:
reg-tests/server/cli_delete_server.vtc

In order to increase usability, the "show ssl ocsp-response" also takes
a frontend certificate path as parameter. In such a case, it behaves the
same way as "show ssl cert foo.pem.ocsp".
Instead of having a dedicated httpclient instance and its own code
decorrelated from the actual auto update one, the "update ssl
ocsp-response" will now use the update task in order to perform updates.
Since the cli command allows to update responses that were never
included in the auto update tree, a new flag was added to the
certificate_ocsp structure so that the said entry can be inserted into
the tree "by hand" and it won't be reinserted back into the tree after
the update process is performed. The 'update_once' flag "stole" a bit
from the 'fail_count' counter since it is the one less likely to reach
UINT_MAX among the ocsp counters of the certificate_ocsp structure.
This new logic required that every certificate_ocsp entry contained all
the ocsp-related information at all time since entries that are not
supposed to be configured automatically can still be updated through the
cli. The logic of the ssl_sock_load_ocsp was changed accordingly.
This patch adds the support for the PS algorithms when verifying JWT
signatures (rsa-pss). It was not managed during the first implementation
and previously raised an "Unmanaged algorithm" error.
The tests use the same rsa signature as the plain rsa tests (RS256 ...)
and the implementation simply adds a call to
EVP_PKEY_CTX_set_rsa_padding in the function that manages rsa and ecdsa
signatures.
The signatures in the reg-test were built thanks to the PyJWT python
library once again.
When adding a new certificate through the CLI and appending it to a
crt-list with the 'ocsp-update' option set, the new certificate would
not be added to the OCSP response update list.
The only thing that was missing was the copy of the ocsp_update mode
from the ssl_bind_conf into the ckch_store's object.
An extra wakeup of the update task also needed to happen in case the
newly inserted entry needs to be updated before the next wakeup of the
task.
This patch does not need to be backported.
Add tests for the "show ssl ocsp-updates" cli command as well as the new
'base64' parameter that can be passed to the "show ssl ocsp-response"
command.
The options were after the filters which does not work well and now
raises a warning. It did not break the regtest because the crt-lists
were not actually used by clients.
Added new testcases for all 4 branches of smp_fetch_hdr_ip():
- a plain IPv4 address
- an IPv4 address with an port number
- a plain IPv6 address
- an IPv6 address wrapped in [] brackets
304 responses contains "Content-length" or "Transfer-encoding"
headers. rxresp action expects to get a payload in this case, even if 304
reponses must not have any payload. A workaround was added to remove these
headers from the 304 responses. However, a better solution is to only get
the response headers from clients using rxresphdrs action.
If a payload is erroneously added in these reponses, the scripts will fail
the same way. So it is safe.
Since commit cc9bf2e5f "MEDIUM: cache: Change caching conditions"
responses that do not have an explicit expiration time are not cached
anymore. But this mechanism wrongly used the TX_CACHE_IGNORE flag
instead of the TX_CACHEABLE one. The effect this had is that a cacheable
response that corresponded to a request having a "Cache-Control:
no-cache" for instance would not be cached.
Contrary to what was said in the other commit message, the "checkcache"
option should not be impacted by the use of the TX_CACHEABLE flag
instead of the TX_CACHE_IGNORE one. The response is indeed considered as
not cacheable if it has no expiration time, regardless of the presence
of a cookie in the response.
This should fix GitHub issue #2048.
This patch can be backported up to branch 2.4.
In this scripts, several clients perform a requests and exit because an SSL
error is expected and thus no response is sent. However, we must explicitly
wait for the connection close, via an "expect_close" statement. Otherwise,
depending on the timing, HAProxy may detect the client abort before any
connection attempt on the server side and no SSL error is reported, making
the script to fail.
If "-dF" command line argument is passed to haproxy to execute the script,
by sepcifying HAPROXY_ARGS variable, http_splicing.vtc is now skipped.
Without this patch, the script fails when the fast-forward is disabled.
A feature command was added to detect if infinite forward is disabled to be
able to skip the script. Unfortunately, it is no supported to evaluate such
expression. Thus remove it. For now, reg-tests must not be executed with
"-dF" option.
The -dF option can now be used to disable data fast-forward. It does the
same than the global option "tune.fast-forward off". Some reg-tests may rely
on this optim. To detect the feature and skip such script, the following
vtest command must be used:
feature cmd "$HAPROXY_PROGRAM -cc '!(globa.tune & GTUNE_NO_FAST_FWD)'"
Add a new test to prevent any regression for the if-none parameter in
the "forwardfor" proxy option.
This will ensure upcoming refactors don't break reference behavior.
The wrong return value was checked, resulting in dead code and
potential bugs.
It should fix GitHub issue #2005.
This patch should be backported up to 2.5.
When the JWT token signature is using ECDSA algorithm (ES256 for
instance), the signature is a direct concatenation of the R and S
parameters instead of OpenSSL's DER format (see section
3.4 of RFC7518).
The code that verified the signatures wrongly assumed that they came in
OpenSSL's format and it did not actually work.
We now have the extra step of converting the signature into a complete
ECDSA_SIG that can be fed into OpenSSL's digest verification functions.
The ECDSA signatures in the regtest had to be recalculated and it was
made via the PyJWT python library so that we don't end up checking
signatures that we built ourselves anymore.
This patch should fix GitHub issue #2001.
It should be backported up to branch 2.5.
The error handling in the HTTP payload forwarding is far to be ideal because
both sides (request and response) are tested each time. It is espcially ugly
on the request side. To report a server error instead of a client error,
there are some workarounds to delay the error handling. The reason is that
the request analyzer is evaluated before the response one. In addition,
errors are tested before the data analysis. It means it is possible to
truncate data because errors may be handled to early.
So the error handling at this stages was totally reviewed. Aborts are now
handled after the data analysis. We also stop to finish the response on
request error or the opposite. As a side effect, the HTTP_MSG_ERROR state is
now useless. As another side effect, the termination flags are now set by
the HTTP analysers and not process_stream().
When we wait for the request body, we are still in the request analysis. So
a SF_FINST_R flag must be reported in logs. Even if some data are already
received, at this staged, nothing is sent to the server.
This patch could be backported in all stable versions.
