When the HTTP forwarder is used, it resets msg->sov so that we know that
the parsing pointer has advanced by exactly (msg->eoh + msg->eol - msg->sov)
bytes which may have to be rewound in case we want to perform an HTTP fetch
after forwarding has started (eg: upon connect).
But when the backend is in TCP mode, there may be no HTTP forwarding
analyser installed, still we may want to perform these HTTP fetches in
case we have already ensured at the TCP layer that we have a properly
parsed HTTP transaction.
In order to solve this, we reset msg->sov before doing a channel_forward()
so that we can still compute http_rewind() on the pending data. That ensures
the buffer is always rewindable even in mixed TCP+HTTP mode.
ARGC_CAP was not added to fmt_directives() which is used to format
error messages when failing to parse log format expressions. The
whole switch/case has been reorganized to match the declaration
order making it easier to spot missing values. The default is not
the "log" directive anymore but "undefined" asking to report the
bug.
Backport to 1.5 is not strictly needed but is desirable at least
for code sanity.
Clients that support ECC cipher suites SHOULD send the specified extension
within the SSL ClientHello message according to RFC4492, section 5.1. We
can use this extension to chain-proxy requests so that, on the same IP
address, a ECC compatible clients gets an EC certificate and a non-ECC
compatible client gets a regular RSA certificate. The main advantage of this
approach compared to the one presented by Dave Zhu on the mailing list
is that we can make it work with OpenSSL versions before 1.0.2.
Example:
frontend ssl-relay
mode tcp
bind 0.0.0.0:443
use_backend ssl-ecc if { req.ssl_ec_ext 1 }
default_backend ssl-rsa
backend ssl-ecc
mode tcp
server ecc unix@/var/run/haproxy_ssl_ecc.sock send-proxy-v2 check
backend ssl-rsa
mode tcp
server rsa unix@/var/run/haproxy_ssl_rsa.sock send-proxy-v2 check
listen all-ssl
bind unix@/var/run/haproxy_ssl_ecc.sock accept-proxy ssl crt /usr/local/haproxy/ecc.foo.com.pem user nobody

The current method of retrieving the incoming connection's destination
address to hash it is not compatible with IPv6 nor the proxy protocol
because it directly tries to get an IPv4 address from the socket. Instead
we must ask the connection. This is only used when no SNI is provided.
In src/51d.c, the function _51d_conv(), a final '\0' is added into
smp->data.str.str, which can cause a problem if the SMP_F_CONST flag is
set in smp->flags or if smp->data.str.size is not available.
This patch adds a check on smp->flags and smp->data.str.size, and copies
the smp->data.str.str to another buffer by using smp_dup(). If necessary,
the "const" flag is set after device detection. Also, this patch removes
the unnecessary call to chunk_reset() on temp argument.
This option enables overriding source IP address in a HTTP request. It is
useful when we want to set custom source IP (e.g. front proxy rewrites address,
but provides the correct one in headers) or we wan't to mask source IP address
for privacy or compliance.
It acts on any expression which produces correct IP address.
This modification makes possible to use sample_fetch_string() in more places,
where we might need to fetch sample values which are not plain strings. This
way we don't need to fetch string, and convert it into another type afterwards.
When using aliased types, the caller should explicitly check which exact type
was returned (e.g. SMP_T_IPV4 or SMP_T_IPV6 for SMP_T_ADDR).
All usages of sample_fetch_string() are converted to use new function.
Compression stats were not easy to read and could be confusing because
the saving ratio could be taken for global savings while it was only
relative to compressible input. Let's make that a bit clearer using
the new tooltips with a bit more details and also report the effective
ratio over all output bytes.
Commit cc87a11 ("MEDIUM: tcp: add register keyword system.") broke the
TCP ruleset by merging custom rules and accept. It was fixed a first time
by commit e91ffd0 ("BUG/MAJOR: tcp: only call registered actions when
they're registered") but the accept action still didn't work anymore
and was causing the matching rule to simply be ignored.
Since the code introduced a very fragile behaviour by not even mentionning
that accept and custom were silently merged, let's fix this once for all by
adding an explicit check for the accept action. Nevertheless, as previously
mentionned, the action should be changed so that custom is the only action
and the continue vs break indication directly comes from the callee.
No backport is needed, this bug only affects 1.6-dev.
All chapters in the configuration documentation used to follow this syntax :
<chapter number>. <title>
-------------------------
The new chapters introduced to document the dns resolution didn't provide the
dot character after the chapter number, which breaks the parsing for the HTML
converter. Instead of adding new conditions in the converter, we can align the
chapters with this syntax.
Until now, the code assumed that it can get the offset to the first TLV
header just by subtracting the length of the TLV part from the length of
the complete buffer. However, if the buffer contains actual data after
the header, this computation is flawed and leads to haproxy trying to
parse TLV headers from the proxied data.
This change fixes this by making sure that the offset to the first TLV
header is calculated based from the start of the buffer -- simply by
adding the size of the proxy protocol v2 header plus the address
family-dependent size of the address information block.
The function buffer_slow_realign() was initially designed for requests
only and did not consider pending outgoing data. This causes a problem
when called on responses where data remain in the buffer, which may
happen with pipelined requests when the client is slow to read data.
The user-visible effect is that if less than <maxrewrite> bytes are
present in the buffer from a previous response and these bytes cross
the <maxrewrite> boundary close to the end of the buffer, then a new
response will cause a realign and will destroy these pending data and
move the pointer to what's believed to contain pending output data.
Thus the client receives the crap that lies in the buffer instead of
the original output bytes.
This new implementation now properly realigns everything including the
outgoing data which are moved to the end of the buffer while the input
data are moved to the beginning.
This implementation still uses a buffer-to-buffer copy which is not
optimal in terms of performance and which should be replaced by a
buffer switch later.
Prior to this patch, the following script would return different hashes
on each round when run from a 100 Mbps-connected machine :
i=0
while usleep 100000; do
echo round $((i++))
set -- $(nc6 0 8001 < 1kreq5k.txt | grep -v '^[0-9A-Z]' | md5sum)
if [ "$1" != "3861afbb6566cd48740ce01edc426020" ]; then echo $1;break;fi
done
The file contains 1000 times this request with "Connection: close" on the
last one :
GET /?s=5k&R=1 HTTP/1.1
The config is very simple :
global
tune.bufsize 16384
tune.maxrewrite 8192
defaults
mode http
timeout client 10s
timeout server 5s
timeout connect 3s
listen px
bind :8001
option http-server-close
server s1 127.0.0.1:8000
And httpterm-1.7.2 is used as the server on port 8000.
After the fix, 1 million requests were sent and all returned the same
contents.
Many thanks to Charlie Smurthwaite of atechmedia.com for his precious
help on this issue, which would not have been diagnosed without his
very detailed traces and numerous tests.
The patch must be backported to 1.5 which is where the bug was introduced.
This is in order to avoid conflicting with NetBSD popcount* functions
since 6.x release, the final l to mentions the argument is a long like
NetBSD does.
This patch could be backported to 1.5 to fix the build issue there as well.
This cache is used by 51d converter. The input User-Agent string, the
converter args and a random seed are used as a hashing key. The cached
entries contains a pointer to the resulting string for specific
User-Agent string detection.
The cache size can be tuned using 51degrees-cache-size parameter.
Moved 51Degrees code from src/haproxy.c, src/sample.c and src/cfgparse.c
into a separate files src/51d.c and include/import/51d.h.
Added two new functions init_51degrees() and deinit_51degrees(), updated
Makefile and other code reorganizations related to 51Degrees.
Commit 4834bc7 ("MEDIUM: vars: adds support of variables") brought a bug.
Setting a variable from an expression that doesn't resolve infinitely
blocks the processing.
The internal actions API must be changed to let the caller pass the various
flags regarding the state of the analysis (SMP_OPT_FINAL).
For now we only fix the issue by making the action_store() function always
return 1 to prevent any blocking.
No backport is needed.
We'll need to move the session variables to the session. For this, the
accounting must not depend on the stream. Instead we pass the pointers
to the different lists.
Commit 7810ad7 ("BUG/MAJOR: lru: fix unconditional call to free due to
unexpected semi-colon") was not enough, it happens that the free() is
not performed at the right place because if the evicted node is recycled,
we must also release its data before it gets overwritten.
No backport is needed.
When Lua is disabled, the alternate functions must have the same
prototype as the original ones, otherwise we get such warnings :
src/stream.c:278:27: warning: too many arguments in call to 'hlua_ctx_destroy'
hlua_ctx_destroy(&s->hlua);
~~~~~~~~~~~~~~~~ ^
No backport is needed.
Dmitry Sivachenko reported the following build warning using Clang, which
is a real bug :
src/log.c:1538:22: warning: use of logical '&&' with constant operand
[-Wconstant-logical-operand]
if (tmp->options && LOG_OPT_QUOTE)
^ ~~~~~~~~~~~~~
The effect is that recent log tags related to HTTP method, path, uri,
query have a bug making them always use quotes.
This bug was introduced in 1.6-dev2 with commit 0ebc55f ("MEDIUM: logs:
Add HTTP request-line log format directives"), so no backport is needed.
Dmitry Sivachenko reported the following build warning using Clang, which
is a real bug :
src/lru.c:133:32: warning: if statement has empty body [-Wempty-body]
if (old->data && old->free);
^
It results in calling old->free(old->data) even when old->free is NULL,
hence crashing on cached patterns.
The same bug appears a few lines below in lru64_destroy() :
src/lru.c:195:33: warning: if statement has empty body [-Wempty-body]
if (elem->data && elem->free);
^
Both were introduced in 1.6-dev2 with commit f90ac55 ("MINOR: lru: Add the
possibility to free data when an item is removed"), so no backport is needed.
Dmitry Sivachenko reported the following harmless build warning using Clang :
src/dumpstats.c:5196:48: warning: address of array 'strm_li(sess)->proto->name'
will always evaluate to 'true' [-Wpointer-bool-conversion]
...strm_li(sess) && strm_li(sess)->proto->name ? strm_li(sess)->proto->nam...
~~ ~~~~~~~~~~~~~~~~~~~~~~^~~~
proto->name cannot be null here as it's the protocol name which is stored
directly in the structure.
The same case is present in 1.5 though the code changed.
Dmitry Sivachenko reported the following build warning using Clang,
though it's harmless :
src/hlua.c:1911:13: warning: variable '_socket_info_expanded_form' is not needed
and will not be emitted [-Wunneeded-internal-declaration]
static char _socket_info_expanded_form[] = SOCKET_INFO_EXPANDED_FORM;
^
Indeed, the variable is not used except to compute a sizeof which is
taken from the string it is initialized from. It probably is a leftover
after various code refactorings. Let's get rid of it now since it's not
used anymore.
No backport is needed.
Dmitry Sivachenko reported the following build warning using Clang
which is a real bug :
src/ssl_sock.c:4104:44: warning: address of 'smp->data.str.len' will always
evaluate to 'true' [-Wpointer-bool-conversion]
if (!smp->data.str.str || !&smp->data.str.len)
The impact is very low however, it will return an empty session_id
instead of no session id when none is found.
The fix should be backported to 1.5.

Commit 31af49d ("MEDIUM: ssl: Add options to forge SSL certificates")
introduced some dependencies on SSL_CTRL_SET_TLSEXT_HOSTNAME for which
a few checks were missing, breaking the build on openssl 0.9.8.
A switch case doesn't have default entry, and the compilator sends
a warning about uninitilized var.
warning: 'vars' may be used uninitialized in this function [-Wmaybe-uninitialized]
This regression was introduce by commit
9c627e84b2 (MEDIUM: sample: Add type any)
New sample type 'any' was not handled in the matrix used to cast
to stick-tables types.
It is possible to propagate entries of any data-types in stick-tables between
several haproxy instances over TCP connections in a multi-master fashion. Each
instance pushes its local updates and insertions to remote peers. The pushed
values overwrite remote ones without aggregation. Interrupted exchanges are
automatically detected and recovered from the last known point.
This patch adds two functions used for variable acces using the
variable full name. If the variable doesn't exists in the variable
pool name, it is created.
This patch adds support of variables during the processing of each stream. The
variables scope can be set as 'session', 'transaction', 'request' or 'response'.
The variable type is the type returned by the assignment expression. The type
can change while the processing.
The allocated memory can be controlled for each scope and each request, and for
the global process.
fix include dependency. The header file sample.h don't need to known
the content of the struct arg, so I remove the include, and replace
it by a simple pointer declaration.
This prevent an include dependecy issue with the next patch.
This patch permits to register a new keyword with the keyword "tcp-request content"
'tcp-request connection", tcp-response content", http-request" and "http-response"
which is identified only by matching the start of the keyword.
for example, we register the keyword "set-var" with the option "match_pfx"
and the configuration keyword "set-var(var_name)" matchs this entry.
This type is used to accept any type of sample as input, and prevent
any automatic "cast". It runs like the type "ADDR" which accept the
type "IPV4" and "IPV6".
The signed values are casted as unsigned before conversion. This patch
use the good converters according with the sample type.
Note: it depends on previous patch to parse signed ints.
